DMO Western Asset Mortgage Opportunity Fund Inc

Certain Interest Rate Transactions

The Fund may enter into various interest rate transactions, such as interest rate swaps and the purchase or sale of interest rate caps and floors. Interest rate swaps involve the exchange by the Fund with a counterparty of their respective commitments to pay either a fixed or floating rate denominated in a particular currency. The Fund may enter into, among other things, fixed-for-floating rate swaps in the same currency, fixed-for-floating rate swaps in different currencies, floating-for-floating rate swaps in the same currency, floating-for-floating rate swaps in different currencies, or fixed-for-fixed rate swaps in different currencies. Fixed-for-floating rate swaps may involve the Fund agreeing with the swap counterparty to pay a fixed rate payment in exchange for the counterparty paying the Fund a variable rate payment that is intended to approximate the Fund’s variable rate payment obligation. Alternatively, fixed-for-floating rate swaps may involve the Fund agreeing with the swap counterparty to pay a floating rate payment in exchange for the counterparty paying the Fund a fixed rate payment. The payment obligation would be based on the notional amount of the swap. The Fund may enter into these transactions to hedge the value of the Fund’s portfolio to seek to increase its return, to preserve a return or spread on a particular investment or portion of its portfolio, or for investment purposes.

The Fund may purchase an interest rate cap, which would require it to pay a premium to the cap counterparty and would entitle the Fund, to the extent that a specified variable rate index exceeds a predetermined fixed rate, to receive from the counterparty payment of the difference based on the notional amount. Alternatively, the Fund may sell an interest rate cap, which would require the cap counterparty to pay a premium to the Fund and would entitle the cap counterparty, to the extent that a specified variable rate index exceeds a predetermined fixed rate, to receive from the Fund payment of the difference based on the notional amount.

The Fund may use interest rate swaps or caps for hedging or investment purposes.

Total Return Swaps

The Fund may enter into total return swaps. In a total return swap, the Fund exchanges with another party their respective commitments to pay or receive the total return of an underlying debt or equity security and a floating local short-term interest rate. The payment obligation would be based on the notional amount of the swap. The Fund may use total return swaps for hedging or investment purposes.

Repurchase Agreements

The Fund may enter into repurchase agreements, in which the Fund purchases a security from a bank or broker-dealer and the bank or broker-dealer agrees to repurchase the security at the Fund’s cost plus interest within a specified time. If the party agreeing to repurchase should default, the Fund will seek to sell the securities which it holds. This could involve transaction costs or delays in addition to a loss on the securities if their value should fall below their repurchase price. Repurchase agreements maturing in more than seven days are considered to be illiquid securities.

Reverse Repurchase Agreements

The Fund may enter into reverse repurchase agreements, under which the Fund will effectively pledge its assets as collateral to secure a short-term loan. Generally, the other party to the agreement makes the loan in an amount equal to a percentage of the market value of the pledged collateral. At the maturity of the reverse repurchase agreement, the Fund will be required to repay the loan and correspondingly receive back its collateral. While used as collateral, the assets continue to pay principal and interest which are for the benefit of the Fund.

When-Issued, Delayed Delivery and Forward Commitment Transactions

The Fund may purchase securities on a when-issued or delayed delivery basis. Securities purchased on a when-issued or delayed delivery basis are purchased for delivery beyond the normal settlement date at a stated price and yield. No income accrues to the purchaser of a security on a when-issued or delayed delivery basis prior to delivery. Such securities are recorded as an asset and are subject to changes in value based upon changes in the general level of interest rates. The Fund will make commitments to purchase securities on a when-issued or delayed delivery basis only with the intention of actually acquiring the securities but may sell them before the settlement date if it is deemed advisable. Purchasing a security on a when-issued or delayed delivery basis can involve a risk that the market price at the time of delivery may be lower than the agreed-upon purchase price, in which case there could be an unrealized loss at the time of delivery. If the Fund purchases securities on a when-issued or delayed delivery basis, it will segregate liquid assets, own positions covering its obligations or enter into offsetting transactions. To the extent the Fund covers its commitment under such portfolio management technique, such instrument will not be considered a senior security for the purposes of the 1940 Act. See “The Fund’s Investments—Investment Strategies—Segregation and Cover Requirements.”

New Securities and Other Investment Techniques

New types of securities and other investment and hedging practices are developed from time to time. Western Asset expects, consistent with the Fund’s investment objectives and policies, to invest in such new types of securities and to engage in such new types of investment practices if Western Asset believes that these investments and investment techniques may assist the Fund in achieving its investment objectives. In addition, Western Asset may use investment techniques and instruments that are not specifically described herein.

Portfolio Turnover

The Fund does not have a formal portfolio turnover policy and does not intend to adopt one. Although the Fund generally intends to hold most of its RMBS and CMBS until maturity, it may, from time to time, sell any of its RMBS and CMBS as part of its overall management of its investment portfolio. When investments are realized, Western Asset will reinvest proceeds therefrom in the Fund’s target assets. Depending on market conditions, Western Asset will also make opportunistic dispositions of the Fund’s investments in its target assets. Frequent trading also increases transaction costs, which could detract from the Fund’s performance.

Fundamental Investment Policies

The Fund’s (i) investment objectives and (ii) the investment restrictions listed in the SAI, are considered fundamental and may not be changed without the approval of the holders of a majority of the outstanding Common Stock (or Preferred Stock, if any). A “majority of the outstanding” shares means (i) 67% or more of the shares present at a meeting, if the holders of more than 50% of the shares outstanding are present or represented by proxy or (ii) more than 50% of the shares outstanding, whichever of (i) or (ii) is less. See “Investment Restrictions” in the SAI for a complete list of the fundamental and non-fundamental investment policies of the Fund.

35

LEVERAGE

The Fund may seek to enhance the level of its current distributions to Common Stockholders through the use of leverage. In an effort to mitigate the overall risk of leverage, the Fund does not intend to incur leverage that exceeds 33 ¹/₃% of the Fund’s Managed Assets immediately after Borrowings and/or issuances of Preferred Stock.

The Fund may use leverage through Borrowings, including loans from certain financial institutions, to the extent available to the Fund), the use of reverse repurchase agreements and/or the issuance of debt securities and possibly through the issuance of Preferred Stock, in an aggregate amount of up to approximately 33 ¹/₃% of the Fund’s Managed Assets immediately after such Borrowings and/or issuances of Preferred Stock. However, the Fund may borrow up to an aggregate amount of $55,000,000 ($60,000,000 prior to August 13, 2020 and $105,000,000 prior to July 10, 2020) under its revolving credit agreement. As of March 31, 2021, the Fund has $45,000,000 (or 27.53% of net assets) of borrowings outstanding under its revolving credit agreement. In addition, the Fund may enter into additional reverse repurchase agreements and use similar investment management techniques that may provide leverage, but which are not subject to the foregoing 33 ¹/₃% limitation so long as the Fund has covered its commitment with respect to such techniques by segregating liquid assets, entering into offsetting transactions or owning positions covering its obligations. The Fund may not use leverage at all times and the amount of leverage may vary depending upon a number of factors, including LMPFA’s and Western Asset’s outlook for the market and the costs that the Fund would incur as a result of such leverage.

Currently, the Fund has no intention to use leverage through the issuance of notes or debt securities or Preferred Stock, but circumstances may arise such that the Fund may choose to issue Preferred Stock. Borrowings (and any Preferred Stock) will have seniority over Common Stock. Any Borrowings and Preferred Stock (if issued) will leverage your investment in Common Stock. Holders of Common Stock will bear the costs associated with any Borrowings, and if the Fund issues Preferred Stock, Common Stockholders will bear the offering costs of the Preferred Stock issuance. The Board of Directors of the Fund may authorize the use of leverage through Borrowings and Preferred Stock without the approval of the Common Stockholders.

Changes in the value of the Fund’s portfolio securities, including costs attributable to Borrowings or Preferred Stock, will be borne entirely by the holders of the Common Stock. If there is a net decrease (or increase) in the value of the Fund’s investment portfolio, the leverage will decrease (or increase) the net asset value per Common Stock to a greater extent than if the Fund were not leveraged. During periods when the Fund is using leverage through Borrowings or the issuance of Preferred Stock the fees paid to LMPFA, Western Asset and Western Asset Limited for advisory services will be higher than if the Fund did not use leverage because the fees paid will be calculated on the basis of the Fund’s Managed Assets, which includes the principal amount of the Borrowings and any assets attributable to the issuance of Preferred Stock. This means that LMPFA, Western Asset, and Western Asset Limited may have a financial incentive to increase the Fund’s use of leverage.

Under the 1940 Act, the Fund generally is not permitted to issue commercial paper or notes or borrow unless immediately after the borrowing or commercial paper or note issuance the value of the Fund’s total assets less liabilities other than the principal amount represented by commercial paper, notes or borrowings is at least 300% of such principal amount. In addition, the Fund is not permitted to declare any cash dividend or other distribution on its Common Stock unless, at the time of such declaration, the value of the Fund’s total assets, less liabilities other than the principal amount represented by commercial paper, notes or borrowings, is at least 300% of such principal amount after deducting the amount of such dividend or distribution. If the Fund borrows, the Fund intends, to the extent possible, to prepay all or a portion of the principal amount of any outstanding commercial paper, notes or borrowing to the extent necessary to maintain the required asset coverage. Failure to maintain certain asset coverage requirements could result in an event of default and entitle the debt holders to elect a majority of the Board of Directors.

Utilization of leverage is a speculative investment technique and involves certain risks to the holders of Common Stock. These include the possibility of higher volatility of the net asset value of the Common Stock and potentially more volatility in the market value of, and distributions on, the Common Stock. So long as the Fund is able to realize a higher net return on its investment portfolio than the then-current cost of any leverage together with other related expenses, the effect of the leverage will be to cause holders of Common Stock to realize a higher rate of return than if the Fund were not so leveraged. On the other hand, to the extent that the then-current cost of any leverage, together with other related expenses, approaches the net return on the Fund’s investment portfolio, the benefit of leverage to holders of Common Stock will be reduced, and if the then-current cost of any leverage together with related expenses were to exceed the net return on the Fund’s portfolio, the Fund’s leveraged capital structure would result in a lower rate of return to holders of Common Stock than if the Fund were not so leveraged. There can be no assurance that the Fund’s leveraging strategy will be successful.

36

Under the 1940 Act, the Fund is not permitted to issue Preferred Stock unless immediately after such issuance the value of the Fund’s asset coverage is at least 200% of the liquidation value of the outstanding Preferred Stock (i.e., such liquidation value may not exceed 50% of the Fund’s asset coverage less all liabilities other than borrowings).

In addition, the Fund is not permitted to declare any cash dividend or other distribution on its Common Stock unless, at the time of such declaration, the value of the Fund’s asset coverage less liabilities other than borrowings satisfies the above-referenced 200% coverage requirement. If Preferred Stock is issued, the Fund intends, to the extent possible, to purchase or redeem Preferred Stock from time to time to the extent necessary in order to maintain coverage of at least 200%.

If Preferred Stock is outstanding, two of the Fund’s Directors will be elected by the holders of Preferred Stock, voting separately as a class. The remaining Directors of the Fund will be elected by holders of Common Stock and Preferred Stock voting together as a single class. In the unlikely event that the Fund fails to pay dividends on the Preferred Stock for two years, holders of Preferred Stock would be entitled to elect a majority of the Directors of the Fund. The failure to pay dividends or make distributions could result in the Fund ceasing to qualify as a regulated investment company under the Code, which could have a material adverse effect on the value of the Common Stock.

The Fund may be subject to certain restrictions imposed either by guidelines of a lender, if the Fund borrows from a lender, or by one or more rating agencies which may issue ratings for Preferred Stock or debt securities. These guidelines may impose asset coverage or portfolio composition requirements that are more stringent than those imposed on the Fund by the 1940 Act. It is not anticipated that these covenants or guidelines will impede LMPFA, Western Asset, and Western Asset Limited from managing the Fund’s portfolio in accordance with the Fund’s investment objectives and policies. In addition to other considerations, to the extent that the Fund believes that the covenants and guidelines required by the rating agencies would impede its ability to meet its investment objectives, or if the Fund is unable to obtain its desired rating on Preferred Stock or debt securities, the Fund will not issue Preferred Stock or debt securities.

Effects of Leverage

The Fund may borrow up to an aggregate amount of $55,000,000 ($60,000,000 prior to August 13, 2020 and $105,000,000 prior to July 10, 2020) under its revolving credit agreement. The credit agreement renews daily for a 150-day term unless notice to the contrary is given to the Fund, and has a scheduled maturity date of August 13, 2022. At March 31, 2021, the Fund had $45,000,000 of borrowings outstanding per this credit agreement.

The following table is furnished in response to requirements of the SEC. It is designed to illustrate the effect of leverage on Common Stock total return, assuming investment portfolio total returns (comprised of income and changes in the value of securities held in the Fund’s portfolio) of -10%, -5%, 0%, 5% and 10%. These assumed investment portfolio returns are hypothetical figures and are not necessarily indicative of the investment portfolio returns experienced or expected to be experienced by the Fund. See “Risks.”

The table further reflects the issuance of leverage representing 21% of the Fund’s Managed Assets, net of expenses, the Fund’s currently projected annual interest on its leverage of 1.8875%.

37

Common Stock Total Return is composed of two elements: the Common Stock dividends paid by the Fund (the amount of which is largely determined by the net investment income of the Fund after paying dividends or interest on its leverage) and gains or losses on the value of the securities the Fund owns. As required by SEC rules, the table above assumes that the Fund is more likely to suffer capital losses than to enjoy capital appreciation. For example, to assume a total return of 0% the Fund must assume that the interest it receives on its debt security investments is entirely offset by losses in the value of those investments.

38

RISKS

The Fund is a non-diversified, closed-end management investment company designed primarily as a long-term investment and not as a trading vehicle. The Fund is not intended to be a complete investment program and, due to the uncertainty inherent in all investments, there can be no assurance that the Fund will achieve its investment objectives. The Fund’s performance and the value of its investments will vary in response to changes in interest rates, inflation, the financial condition of a security’s issuer, ratings on a security and other market factors. Your securities at any point in time may be worth less than you invested, even after taking into account the reinvestment of Fund dividends and distributions. Below are the principal risks associated with an investment in the Fund.

Investment and Market Risk

An investment in the Fund is subject to investment risk, including the possible loss of the entire amount that you invest. Your investment in Common Stock represents an indirect investment in the MBS and other assets owned by the Fund. An investment in our Common Stock is not intended to constitute a complete investment program and should not be viewed as such. The value of the Fund’s portfolio securities may move up or down, sometimes rapidly and unpredictably. The Fund intends to take advantage of current market dislocations by buying MBS and other securities at depressed prices, but if such dislocations do not persist during the period when the Fund is investing the net proceeds of this offering, the Fund’s returns may be adversely affected. In addition, if the current global economic downturn continues or deteriorates further, the ability of borrowers to service their obligations could be materially and adversely affected. At any point in time, your Common Stock may be worth less than your original investment, even after taking into account the reinvestment of Fund dividends and distributions. We are primarily a long-term investment vehicle and should not be used for short-term trading.

Market Price Discount from Net Asset Value Risk

The Fund’s Common Stock has traded both at a premium and at a discount to its net asset value. The last reported sale price, as of April 28, 2021 was $15.12 per share. The Fund’s net asset value per share and percentage premium to net asset value per share of its Common Stock as of April 28, 2021 were $14.95 and 1.14%, respectively. There is no assurance that this premium will continue after the date of this Prospectus or that the Fund’s Common Stock will trade at a discount. Shares of closed-end investment companies frequently trade at a discount to their net asset value. This characteristic is a risk separate and distinct from the risk that our net asset value could decrease as a result of the Fund’s investment activities and may be greater for investors expecting to sell their shares in a relatively short period following completion of any offering under this Prospectus. Although the value of the Fund’s net assets is generally considered by market participants in determining whether to purchase or sell shares, whether investors will realize gains or losses upon the sale of the Fund’s Common Stock depends upon whether the market price of the Fund’s Common Stock at the time of sale is above or below the investor’s purchase price for the Fund’s Common Stock. Because the market price of the Fund’s Common Stock is affected by factors such as net asset value, dividend or distribution levels (which are dependent, in part, on expenses), supply of and demand for the Fund’s Common Stock, stability of distributions, trading volume of the Fund’s Common Stock, general market and economic conditions, and other factors beyond our control, the Fund cannot predict whether the Common Stock will trade at, below or above net asset value or at, below or above the offering price. The Fund’s Common Stock is designed primarily for long-term investors and you should not view the Fund as a vehicle for trading purposes.

Risks Related to Investments in MBS

Investing in MBS entails various risks: credit risks, liquidity risks, interest rate risks, market risks, operations risks, structural risks, geographical concentration risks, basis risks and legal risks. Most MBS are subject to the significant credit risks inherent in the underlying collateral and to the risk that the servicer fails to perform. MBS are subject to risks associated with their structure and execution, including the process by which principal and interest payments are allocated and distributed to investors, how credit losses affect the issuing vehicle and the return to investors in such MBS, whether the collateral represents a fixed set of specific assets or accounts, whether the underlying collateral assets are revolving or closed-end, under what terms (including maturity of the MBS) any remaining balance in the accounts may revert to the issuing entity and the extent to which the entity that is the actual source of the collateral assets is obligated to provide support to the issuing vehicle or to the investors in such MBS. In addition, concentrations of MBS of a particular type, as well as concentrations of MBS issued or guaranteed by affiliated obligors, serviced by the same servicer or backed by underlying collateral located in a specific geographic region, may subject the MBS to additional risk.

39

The risks associated with MBS include: (1) credit risk associated with the performance of the underlying mortgage properties and of the borrowers owning these properties; (2) adverse changes in economic conditions and circumstances, which are more likely to have an adverse impact on MBS secured by loans on certain types of commercial properties than on those secured by loans on residential properties; (3) prepayment risk, which can lead to significant fluctuations in value of the MBS; (4) loss of all or part of the premium, if any, paid; and (5) decline in the market value of the security, whether resulting from changes in interest rates, prepayments on the underlying mortgage collateral or perceptions of the credit risk associated with the underlying mortgage collateral.

MBS represent an interest in a pool of mortgages. When market interest rates decline, more mortgages are refinanced and the securities are paid off earlier than expected. Prepayments may also occur on a scheduled basis or due to foreclosure. When market interest rates increase, the market values of MBS decline. At the same time, however, mortgage refinancings and prepayments slow, lengthening the effective maturities of these securities. As a result, the negative effect of the rate increase on the market value of MBS is usually more pronounced than it is for other types of debt securities. In addition, due to increased instability in the credit markets, the market for some MBS has experienced reduced liquidity and greater volatility with respect to the value of such securities, making it more difficult to value such securities.

Moreover, the relationship between borrower prepayments and changes in interest rates may mean some high-yielding mortgage-related and asset-backed securities have less potential for increases in value if market interest rates were to fall than conventional bonds with comparable maturities. In addition, in periods of falling interest rates, the rate of prepayments tends to increase. During such periods, the reinvestment of prepayment proceeds by the Fund will generally be at lower rates than the rates that were carried by the obligations that have been prepaid. Because of these and other reasons, mortgage-related and asset-backed security’s total return and maturity may be difficult to predict precisely. To the extent that the Fund purchases mortgage-related securities at a premium, prepayments (which may be made without penalty) may result in loss of the Fund’s principal investment to the extent of premium paid.

The Fund’s success depends on the Western Asset’s ability to analyze the relationship of changing interest rates on prepayments of the mortgage loans that underlie the Fund’s MBS. Changes in interest rates and prepayments affect the market price of the target assets that the Fund intends to purchase and any target assets that the Fund holds at a given time. As part of the Fund’s overall portfolio risk management, Western Asset will analyze interest rate changes and prepayment trends separately and collectively to assess their effects on the Fund’s investment portfolio. In conducting its analysis, Western Asset will depend on certain assumptions based upon historical trends with respect to the relationship between interest rates and prepayments under normal market conditions. If the recent dislocations in the mortgage market or other developments change the way that prepayment trends have historically responded to interest rate changes, Western Asset’s ability to (1) assess the market value of the Fund’s investment portfolio, (2) implement any hedging strategies and (3) implement techniques to reduce prepayment rate volatility would be significantly affected, which could materially adversely affect the Fund’s financial position and results of operations.

In general, losses on a mortgaged property securing a mortgage loan included in a securitization will be borne first by the equity holder of the property, then by a cash reserve fund or letter of credit, if any, then by the holder of a mezzanine loan or B-Note, if any, then by the “first loss” subordinated security holder (generally, the “B-Piece” buyer) and then by the holder of a higher-rated security. In the event of default and the exhaustion of any equity support, reserve fund, letter of credit, mezzanine loans or B-Notes, and any classes of securities junior to those in which the Fund invests, the Fund will not be able to recover all of its investment in the MBS it purchases. MBS in which the Fund invests may not contain reserve funds, letters of credit, mezzanine loans and/or junior classes of securities. The prices of lower credit quality securities are generally less sensitive to interest rate changes than more highly rated investments, but more sensitive to adverse economic downturns or individual issuer developments.

MBS generally are classified as either CMBS or RMBS, each of which are subject to certain specific risks as further described below. See “—Non-Agency RMBS Risk” and “—CMBS Risk.”

40

Non-Agency RMBS Risk

Non-agency RMBS are securities issued by non-governmental issuers, the payments on which depend (except for rights or other assets designed to assure the servicing or timely distribution of proceeds to holders of such securities) primarily on the cash flow from residential mortgage loans made to borrowers that are secured (on a first priority basis or second priority basis, subject to permitted liens, easements and other encumbrances) by residential real estate (one- to four- family properties) the proceeds of which are used to purchase real estate and purchase or construct dwellings thereon (or to refinance indebtedness previously so used). Non-agency RMBS have no direct or indirect government guarantees of payment and are subject to various risks as described herein.

Credit-Related Risk Associated with Borrowers on Non-Agency RMBS. Credit-related risk on non-agency RMBS arises from losses due to delinquencies and defaults by the borrowers in payments on the underlying mortgage loans and breaches by originators and servicers of their obligations under the underlying documentation pursuant to which the non-agency RMBS are issued. Residential mortgage loans are obligations of the borrowers thereunder only and are not typically insured or guaranteed by any other person or entity. The rate of delinquencies and defaults on residential mortgage loans and the aggregate amount of the resulting losses will be affected by a number of factors, including general economic conditions, particularly those in the area where the related mortgaged property is located, the level of the borrower’s equity in the mortgaged property and the individual financial circumstances of the borrower. If a residential mortgage loan is in default, foreclosure on the related residential property may be a lengthy and difficult process involving significant legal and other expenses. The net proceeds obtained by the holder on a residential mortgage loan following the foreclosure on the related property may be less than the total amount that remains due on the loan. The prospect of incurring a loss upon the foreclosure of the related property may lead the holder of the residential mortgage loan to restructure the residential mortgage loan or otherwise delay the foreclosure process.

Impact of Real Estate and Mortgage Loan Markets on Non-Agency RMBS. In addition to the foregoing considerations, the market for defaulted residential mortgage loans and foreclosed real estate properties may be very limited. In particular, the economic conditions that lead to a higher rate of delinquencies and defaults on a portfolio of real estate mortgage loans may also lead to a reduction in the value of the related real estate properties, which in turn will result in greater losses upon a foreclosure of the real estate properties. At any one time, a portfolio of non-agency RMBS may be backed by residential mortgage loans that are highly concentrated in only a few states or regions. As a result, the performance of such residential mortgage loans may be more susceptible to a downturn in the economy, including in particular industries that are highly represented in such states or regions, natural calamities and other adverse conditions affecting such areas. In addition, the residential mortgage loans underlying non-agency RMBS may include so-called “jumbo” residential mortgage loans, having original principal balances that are significantly higher than is generally the case for residential mortgage loans. If the portfolio of residential mortgage loans underlying a non-agency RMBS includes a high concentration of “jumbo” residential mortgage loans, the performance of the non-agency RMBS will be more susceptible to the performance of individual borrowers and adverse economic conditions in general than would otherwise be the case.

Another factor that may contribute to, and may in the future result in, higher delinquency and default rates is the increase in monthly payments on adjustable-rate mortgage loans. Any increase in prevailing market interest rates may result in increased payments for borrowers who have adjustable-rate mortgage loans. Moreover, with respect to hybrid mortgage loans after their initial fixed-rate period or other so-called adjustable-rate mortgage loans, interest-only products or products having a lower rate, and with respect to mortgage loans with a negative amortization feature which reach their negative amortization cap, borrowers may experience a substantial increase in their monthly payment even without an increase in prevailing market interest rates. Increases in payments for borrowers may result in increased rates of delinquencies and defaults on residential mortgage loans underlying the non-agency RMBS. The past performance of the market for non-agency RMBS is not a reliable indicator of future performance because of the unprecedented and unpredictable performance of the residential mortgage loan market.

As a result of rising concerns about increases in delinquencies and defaults on residential mortgage loans (particularly on subprime and adjustable-rate mortgage loans) and as a result of increasing concerns about the financial strength of originators and servicers and their ability to perform their obligations with respect to non-agency RMBS, there may be an adverse change in the market sentiments of investors about the market values and volatility and the degree of risk of non-agency RMBS generally. Some or all of the underlying residential mortgage

41

loans in an issue of non-agency RMBS may have balloon payments due on their respective maturity dates. Balloon residential mortgage loans involve a greater risk to a lender than fully amortizing loans, because the ability of a borrower to pay such amount will normally depend on its ability to obtain refinancing of the related mortgage loan or sell the related mortgaged property at a price sufficient to permit the borrower to make the balloon payment, which will depend on a number of factors prevailing at the time such refinancing or sale is required, including, without limitation, the strength of the local or national residential real estate markets, interest rates and general economic conditions and the financial condition of the borrower. If borrowers are unable to make such balloon payments, the related issue of non-agency RMBS may experience losses.

Prepayment Risk Associated with Non-Agency RMBS. Non-agency RMBS are susceptible to prepayment risks. Except in the case of certain types of non-agency RMBS, the mortgage loans underlying non-agency RMBS generally do not contain prepayment penalties and a reduction in market interest rates will increase the likelihood of prepayments on the related non-agency RMBS, resulting in a reduction in yield to maturity for most holders of such securities. In the case of certain home equity loan securities and certain types of non-agency RMBS, even though the underlying mortgage loans often contain prepayment premiums, such prepayment premiums may not be sufficient to discourage borrowers from prepaying their mortgage loans in the event of a reduction in market interest rates, resulting in a reduction in the yield to maturity for holders of the related non-agency RMBS. In addition to reductions in the level of market interest rates and the prepayment provisions of the mortgage loans, repayments on the residential mortgage loans underlying an issue of non-agency RMBS may also be affected by a variety of economic, geographic and other factors, including the size difference between the interest rates on the underlying residential mortgage loans (giving consideration to the cost of refinancing) and prevailing mortgage rates and the availability of refinancing. In general, if prevailing interest rates fall significantly below the interest rates on the related residential mortgage loans, the rate of prepayment on the underlying residential mortgage loans would be expected to increase. Conversely, if prevailing interest rates rise to a level significantly above the interest rates on the related mortgage loans, the rate of prepayment would be expected to decrease. Prepayments could reduce the yield received on the related issue of non-agency RMBS.

Non-agency RMBS typically contain provisions that require repurchase of mortgage loans by the originator or other seller in the event of a breach of a representation or warranty regarding loan quality and characteristics of such loan. Any repurchase of a mortgage loan as a result of a breach has the same effect on the yield received on the related issue of non-agency RMBS as a prepayment of such mortgage loan. Any increase in breaches of representations and the consequent repurchases of mortgage loans that result from inadequate underwriting procedures and policies and protections against fraud will have the same effect on the yield on the related non-agency RMBS as an increase in prepayment rates. CMBS are also subject to prepayment risk, as described above. Risk of prepayment may be reduced for commercial real estate property loans containing significant prepayment penalties or prohibitions on principal payments for a period of time following origination.

The Fund may also invest in MBS which are IO securities and PO securities. An IO security receives some or all of the interest portion of the underlying collateral and little or no principal. A reference principal value called a notional value is used to calculate the amount of interest due. IO securities are sold at a deep discount to their notional principal amount. A PO security does not receive any interest, is priced at a deep discount to its redemption value and ultimately receives the redemption value. Generally speaking, when interest rates are falling and prepayment rates are increasing, the value of a PO security will rise and the value of an IO security will fall. Conversely, when interest rates are rising and prepayment rates are decreasing, generally the value of a PO security will fall and the value of an IO security will rise.

Legal Risks Associated with Non-Agency RMBS. Legal risks can arise as a result of the procedures followed in connection with the origination of the mortgage loans or the servicing thereof which may be subject to various federal and state laws (including, without limitation, predatory lending laws), public policies and principles of equity regulating interest rates and other charges, require certain disclosures, require licensing of originators, prohibit discriminatory lending practices, regulate the use of consumer credit information and debt collection practices and may limit the servicer’s ability to collect all or part of the principal of or interest on a residential mortgage loan, entitle the borrower to a refund of amounts previously paid by it or subject the servicer to damages and sanctions. Specifically, provisions of federal predatory lending laws, such as the federal Truth-in-Lending Act (as supplemented by the Home Ownership and Equity Protection Act of 1994) and Regulation Z, and various enacted state predatory lending laws provide that a purchaser or assignee of specified types of residential mortgage loans

42

(including an issuer of non-agency RMBS) may be held liable for violations by the originator of such mortgage loans. Under such assignee liability provisions, a borrower is generally given the right to assert against a purchaser of its mortgage loan any affirmative claims and defenses to payment such borrower could assert against the originator of the loan or, where applicable, the home improvement contractor that arranged the loan. Liability under such assignee liability provisions could, therefore, result in a disruption of cash flows allocated to the holders of non-agency RMBS where either the issuer of such non-agency RMBS is liable in damages or is unable to enforce payment by the borrower. In most but not all cases, the amount recoverable against a purchaser or assignee under such assignee liability provisions is limited to amounts previously paid and still owed by the borrower. Moreover, sellers of residential mortgage loans to an issuer of non-agency RMBS typically represent that the loans have been originated in accordance with all applicable laws and in the event such representation is breached, the seller typically must repurchase the offending loan.

Notwithstanding these protections, an issuer of non-agency RMBS may be exposed to an unquantifiable amount of potential assignee liability because, first, the amount of potential assignee liability under certain predatory lending laws is unclear and has yet to be litigated, and, second, in the event a predatory lending law does not prohibit class action lawsuits, it is possible that an issuer of non-agency RMBS could be liable in damages for more than the original principal amount of the offending loans held by it. In such circumstances the issuer of non-agency RMBS may be forced to seek contribution from other parties, who may no longer exist or have adequate funds available to fund such contribution.

In addition, structural and legal risks of non-agency RMBS include the possibility that, in a bankruptcy or similar proceeding involving the originator or the servicer (often the same entity or affiliates), the assets of the issuer could be treated as never having been truly sold by the originator to the issuer and could be substantively consolidated with those of the originator, or the transfer of such assets to the issuer could be voided as a fraudulent transfer. Challenges based on such doctrines could result also in cash flow delays and losses on the related issue of non-agency RMBS.

In some cases, servicers of non-agency RMBS have been the subject of legal proceedings involving the origination and/or servicing practices of such servicers. Large groups of private litigants and states attorneys general have brought such proceedings. Because of the large volume of mortgage loans originated and serviced by such servicers, such litigation can cause heightened financial strain on servicers. In other cases, origination and servicing practices may cause or contribute to such strain, because of representation and warranty repurchase liability arising in MBS and mortgage loan sale transactions. Any such financial strain could cause servicers to service below required standards, causing delinquencies and losses in any related MBS transaction to rise, and in extreme cases could cause the servicer to seek the protection of any applicable bankruptcy or insolvency law. In any such proceeding, it is unclear whether the fees that the servicer charges in such transactions would be sufficient to permit that servicer or a successor servicer to service the mortgage loans in such transaction adequately. If such fees had to be increased, it is likely that the most subordinated security holders in such transactions would be effectively required to pay such increased fees. Finally, these entities may be the subject of future laws designed to protect consumers from defaulting on their mortgage loans. Such laws may have an adverse effect on the cash flows paid under such non-agency RMBS.

In the past year, a number of lenders specializing in residential mortgages have sought bankruptcy protection, shut down or been refused further financings from their lenders. In addition, certain lenders who service and/or issue non-agency RMBS have announced that they are being investigated by or have received information requests from U.S. federal and/or state authorities, including the Securities and Exchange Commission. As a result of such investigations and other similar investigations and general concerns about the adequacy or accuracy of disclosure of risks to borrowers and their understanding of such risks, U.S. financial regulators have indicated that they may propose new guidelines for the mortgage industry. Guidelines, if introduced, together with the other factors described herein, may make it more difficult for borrowers with weaker credit to refinance, which may lead to further increases in delinquencies, extensions in duration and losses in mortgage-related assets. Furthermore, because some mortgage loans have high recoveries, and as property values decline, increasing loan-to-value ratios, recoveries on some defaulted mortgage loans are more likely to be less than the amounts owed under such mortgage loans, resulting in higher net losses than would have been the case had property values remained the same or increased.

CMBS Risk

CMBS are, generally, securities backed by obligations (including certificates of participation in obligations) that are principally secured by mortgages on real property or interests therein having a multifamily or commercial use, such as regional malls, other retail space, office buildings, industrial or warehouse properties, hotels, nursing homes and senior living centers. The market for CMBS developed more recently and, in terms of total outstanding principal amount of issues, is relatively small compared to the market for residential single-family mortgage-related securities. CMBS are subject to particular risks, including lack of standardized terms, shorter maturities than residential mortgage loans and payment of all or substantially all of the principal only at maturity rather than regular amortization of principal. Additional risks may be presented by the type and use of a particular commercial property. Special risks are presented by hospitals, nursing homes, hospitality properties and certain other property types. Commercial property values and net operating income are subject to volatility, which may result in net operating income becoming insufficient to cover debt service on the related mortgage loan. The repayment of loans secured by income-producing properties is typically dependent upon the successful operation of the related real estate project rather than upon the liquidation value of the underlying real estate. Furthermore, the net operating income from and value of any commercial property is subject to various risks, including changes in general or local economic conditions and/or specific industry segments; the solvency of the related tenants; declines in real estate values; declines in rental or occupancy rates; increases in interest rates, real estate tax rates and other operating expenses; changes in governmental rules, regulations and fiscal policies; acts of God; terrorist threats and attacks and social unrest and civil disturbances. Consequently, adverse changes in economic conditions and circumstances are more likely to have an adverse impact on mortgage-related securities secured by loans on commercial properties than on those secured by loans on residential properties. In addition, commercial lending generally is viewed as exposing the lender to a greater risk of loss than one- to four- family residential lending. Commercial lending, for example, typically involves larger loans to single borrowers or groups of related borrowers than residential one- to four- family mortgage loans. In addition, the repayment of loans secured by income producing properties typically is dependent upon the successful operation of the related real estate project and the cash flow generated therefrom.

The exercise of remedies and successful realization of liquidation proceeds relating to CMBS is also highly dependent on the performance of the servicer or special servicer. In many cases, overall control over the special servicing of related underlying mortgage loans will be held by a “directing certificateholder” or a “controlling class representative,” which is appointed by the holders of the most subordinate class of CMBS in such series. The Fund may not have the right to appoint the directing certificateholder. In connection with the servicing of the specially serviced mortgage loans, the related special servicer may, at the direction of the directing certificateholder, take actions with respect to the specially serviced mortgage loans that could adversely affect the Fund’s interests. There may be a limited number of special servicers available, particularly those that do not have conflicts of interest.

Western Asset will value the Fund’s potential CMBS investments based on loss-adjusted yields, taking into account estimated future losses on the mortgage loans included in the securitization’s pool of loans, and the estimated impact of these losses on expected future cash flows. Western Asset’s loss estimates may not prove accurate, as actual results may vary from estimates. In the event that Western Asset overestimates the pool level losses relative to the price the Fund pays for a particular CMBS investment, the Fund may experience losses with respect to such investment.

Interest Rate Risk Associated with Non-Agency RMBS and CMBS

The rate of interest payable on certain non-agency RMBS and CMBS may be set or effectively capped at the weighted average net coupon of the underlying mortgage loans themselves, often referred to as an “available funds cap.” As a result of this cap, the return to the holder of such non-agency RMBS and CMBS is dependent on the relative timing and rate of delinquencies and prepayments of mortgage loans bearing a higher rate of interest. In general, early prepayments will have a greater negative impact on the yield to the holder of such non-agency RMBS and CMBS.

The value of fixed rate debt securities can be expected to vary inversely with changes in prevailing interest rates. Fixed rate debt securities with longer maturities, which tend to produce higher yields, are subject to potentially greater capital appreciation and depreciation than securities with shorter maturities.

44

Structural Risks Associated with Non-Agency RMBS and CMBS

Because non-agency RMBS generally are ownership or participation interests in pools of mortgage loans secured by a pool of one- to four-family residential properties underlying the mortgage loan pool, the non-agency RMBS are entitled to payments provided for in the underlying agreement only when and if funds are generated by the underlying mortgage loan pool. This likelihood of the return of interest and principal may be assessed as a credit matter. However, the holders of non-agency RMBS do not have the legal status of secured creditors, and cannot accelerate a claim for payment on their securities, or force a sale of the mortgage loan pool in the event that insufficient funds exist to pay such amounts on any date designated for such payment. The holders of non-agency RMBS do not typically have any right to remove a servicer solely as a result of a failure of the mortgage pool to perform as expected. A similar risk is associated with CMBS.

Subordination Risk Associated with Non-Agency RMBS and CMBS

The non-agency RMBS and CMBS may be subordinated to one or more other senior classes of securities of the same series for purposes of, among other things, offsetting losses and other shortfalls with respect to the related underlying mortgage loans. For example, in the case of certain non-agency RMBS and CMBS, no distributions of principal will generally be made with respect to any class until the aggregate principal balances of the corresponding senior classes of securities have been reduced to zero. As a result, non-agency RMBS and CMBS may be more sensitive to risk of loss, writedowns, the non-fulfillment of repurchase obligations, overadvancing on a pool of loans and the costs of transferring servicing than senior classes of securities.

Credit Risk

Credit risk is the risk that one or more MBS or other securities in the Fund’s portfolio will decline in price, or the issuer thereof will fail to pay interest or principal when due, because the issuer experiences a decline in its financial status. Credit risk is increased when a portfolio security is downgraded or the perceived creditworthiness of the issuer deteriorates. In general, lower-rated securities carry a greater degree of risk that the issuer will lose its ability to make interest and principal payments, which could have a negative impact on the Fund’s net asset value or dividends and on the market price of the Common Stock. Ratings may not accurately reflect the actual credit risk associated with a security. If a security satisfies the rating requirements described above at the time of investment and is subsequently downgraded below that rating, the Fund will not be required to dispose of the security. If a downgrade occurs, LMPFA and Western Asset will consider what action, including the sale of the security, is in the best interests of the Fund and its stockholders. There can be no assurance that any action that may be taken by LMPFA or Western Asset will be implemented in a timely manner or that such actions will preserve the value of your investment in the Fund. Securities of below investment grade quality, commonly referred to as junk bonds, are regarded as having predominately speculative characteristics with respect to the issuer’s capacity to pay interest and repay principal when due, and are more susceptible to default or decline in market value due to adverse economic and business developments than investment grade securities. Also, to the extent that the rating assigned to a security in the Fund’s portfolio is downgraded by any NRSRO, the market price and liquidity of such security may be adversely affected. The market values for securities of below investment grade quality tend to be volatile, and these securities are less liquid than investment grade securities, potentially making them difficult to value. Issuers of below investment grade securities are more vulnerable to financial setbacks and recession than more creditworthy issuers, which may impair their ability to make interest and principal payments. It is likely that the current economic recession may severely disrupt the market for such securities and have an adverse impact on the value of such securities. In addition, it is likely that continued economic deterioration may adversely affect the ability of such issuers to repay principal and pay interest on these securities and increase the incidence of default for such securities. For these reasons, an investment in the Fund, compared with a portfolio consisting solely of investment grade securities, may experience the following:

45

Adverse changes in economic conditions are more likely to lead to a weakened capacity of a below investment grade issuer to make principal payments and interest payments compared to an investment grade issuer. The principal amount of below investment grade securities outstanding has proliferated in the past decade as an increasing number of issuers have used below investment grade securities for financing. The current economic downturn may severely affect the ability of highly leveraged issuers to service their debt obligations or to repay their obligations upon maturity. If the current economic downturn continues or worsens, or in the event interest rates rise sharply, increasing the interest cost on variable rate instruments and negatively impacting economic activity, the number of defaults by below investment grade issuers is likely to increase. Similarly, down-turns in profitability in specific industries could adversely affect private activity bonds. The market values of lower quality debt securities tend to reflect the individual circumstances of the issuer to a greater extent than do higher quality securities, which react primarily to fluctuations in the general level of interest rates. Factors having an adverse impact on the market value of lower quality securities may have an adverse impact on the Fund’s net asset value and the market value of its Common Stock. In addition, the Fund may incur additional expenses to the extent it is required to seek recovery upon a default in payment of principal or interest on its portfolio holdings. In certain circumstances, the Fund may be required to foreclose on an issuer’s assets and take possession of its property or operations. In such circumstances, the Fund would incur additional costs in disposing of such assets and potential liabilities from operating any business acquired.

The secondary market for below investment grade securities may not be as liquid as the secondary market for more highly rated securities, a factor that may have an adverse effect on the Fund’s ability to dispose of a particular security. There are fewer dealers in the market for below investment grade securities than in the market for investment grade securities. The prices quoted by different dealers for below investment grade securities may vary significantly, and the spread between the bid and ask price is generally much larger for below investment grade securities than for higher quality instruments. Under adverse market or economic conditions, the secondary market for below investment grade securities could contract further, independent of any specific adverse changes in the condition of a particular issuer, and these instruments may become illiquid. As a result, the Fund could find it more difficult to sell these securities or may be able to sell the securities only at prices lower than if such securities were widely traded. Prices realized upon the sale of such lower rated or unrated securities, under such circumstances, may be less than the prices used in calculating the Fund’s net asset value.

Issuers of below investment grade securities are highly leveraged and may not have available to them more traditional methods of financing. Therefore, the risk associated with acquiring the securities of such issuers generally is greater than is the case with higher rated securities. For example, during an economic downturn or a sustained period of rising interest rates, highly leveraged issuers of below investment grade securities may experience financial stress. During such periods, such issuers may not have sufficient revenues to meet their interest payment obligations. An issuer’s ability to service its debt obligations also may be adversely affected by adverse developments in its business or affairs, the issuer’s inability to meet specific projected forecasts or the unavailability of additional financing. The risk of loss from default by the issuer is significantly greater for the holders of below investment grade securities because such securities are generally unsecured and are often subordinated to other creditors of the issuer. Prices and yields of below investment grade securities will fluctuate over time and, during periods of economic uncertainty, volatility of below investment grade securities may adversely affect the Fund’s net asset value. In addition, investments in below investment grade zero coupon bonds rather than income-bearing below investment grade securities, may be more speculative and may be subject to greater fluctuations in value due to changes in interest rates.

Investments in lower rated or unrated securities may present special tax issues for the Fund to the extent that the issuers of these securities default on their obligations pertaining thereto, and the federal income tax consequences to the Fund as a holder of such securities may not be clear.

46

Interest Rate Risk

Interest rate risk is the risk that the debt securities in the Fund’s portfolio will decline in value because of changes in market interest rates. As interest rates decline, issuers of securities may prepay principal earlier than scheduled, forcing the Fund to reinvest in lower-yielding securities and potentially reducing the Fund’s income. As interest rates increase, slower than expected principal payments may extend the average life of securities, potentially locking in a below-market interest rate and reducing the Fund’s value. In typical market interest rate environments, the prices of longer-term debt securities generally fluctuate more than the prices of shorter-term debt securities as interest rates change. To the extent the Fund invests in debt securities that may be prepaid at the option of the obligor, the sensitivity of such securities to changes in interest rates may increase (to the detriment of the Fund) when interest rates rise. Interest rates are currently low relative to historic levels. The FOMC of the U.S. Federal Reserve has set its target federal funds rate at which depository institutions lend reserve balances to other depository institutions overnight to at or near zero percent and the U.S. Federal Reserve has expanded its balance sheet to increase its purchases of debt securities. In the future, the FOMC may increase or decrease the target federal funds rate, and the U.S. Federal Reserve may increase, decrease or eliminate its purchases of debt securities.

Moreover, because rates on certain floating rate debt securities in which the Fund may invest typically reset only periodically, changes in prevailing interest rates (and particularly sudden and significant changes) can be expected to cause some fluctuations in the Fund’s net asset value. The Fund may utilize certain strategies, including taking positions in futures or interest rate swaps, for the purpose of reducing the interest rate sensitivity of the Fund’s debt securities and decreasing the Fund’s exposure to interest rate risk. The Fund is not required to hedge its exposure to interest rate risk and may choose not to do so. In addition, there is no assurance that any attempts by the Fund to reduce interest rate risk will be successful.

An increase in the interest payments on the Fund’s borrowings relative to the interest it earns on its investment securities may adversely affect the Fund’s profitability. The Fund earns money based upon the spread between the interest payments it earns on its investment securities and the interest payments it must make on its borrowings.

The Fund relies primarily on short-term borrowings to acquire investment securities with long-term maturities. Accordingly, if short-term interest rates increase, this may adversely affect its profitability. Some of the investment securities the Fund may acquire are adjustable-rate securities. This means that their interest rates may vary over time based upon changes in an objective index, such as:

These indices generally reflect short-term interest rates.

The interest rates on the Fund’s borrowings similarly vary with changes in an objective index. Nevertheless, the interest rates on the Fund’s borrowings generally adjust more frequently than the interest rates on its adjustable-rate investment securities. In a period of rising interest rates, the Fund could experience a decrease in net income or a net loss because the interest rates on its borrowings adjust faster than the interest rates on its adjustable-rate investment securities.

In a period of rising interest rates, the Fund’s interest and dividend payments could increase while the interest it earns on its fixed-rate MBS would not change. This would adversely affect the Fund’s profitability.

Rising interest rates generally reduce the demand for mortgage loans due to the higher cost of borrowing. A reduction in the volume of mortgage loans originated may affect the volume of target assets available to the Fund, which could adversely affect the Fund’s ability to acquire assets that satisfy its investment objectives. Rising interest rates may also cause target assets that were issued prior to an interest rate increase to provide yields that are below prevailing market interest rates. If rising interest rates cause the Fund to be unable to acquire a sufficient volume of target assets with a yield that is above the Fund’s borrowing cost, its ability to satisfy its investment objectives and to generate income and make distributions may be materially and adversely affected.

47

The relationship between short-term and longer-term interest rates is often referred to as the “yield curve.” Ordinarily, short-term interest rates are lower than longer-term interest rates. If short-term interest rates rise disproportionately relative to longer-term interest rates (a flattening of the yield curve), the Fund’s borrowing costs may increase more rapidly than the interest income earned on the Fund’s assets. Because the Fund expects that its investments, on average, generally will bear interest based on longer-term rates than its borrowings, a flattening of the yield curve would tend to decrease the Fund’s net income and the market value of its net assets. Additionally, to the extent cash flows from investments that return scheduled and unscheduled principal are reinvested, the spread between the yields on the new investments and available borrowing rates may decline, which would likely decrease the Fund’s net income. It is also possible that short-term interest rates may exceed longer-term interest rates (a yield curve inversion) in which event the Fund’s borrowing costs may exceed its interest income and the Fund could incur operating losses.

Certain financial instruments in which the Fund invests may be tied to the LIBOR to determine payment obligations, financing terms, hedging strategies or investment value. LIBOR is the offered rate for short-term Eurodollar deposits between major international banks. On July 27, 2017, the head of the UK Financial Conduct Authority (“FCA”), which regulates LIBOR, announced a desire to phase out the use of LIBOR by the end of 2021. Subsequently, the FCA and the administrator of LIBOR announced a delay in the phase out of a majority of the U.S. dollar LIBOR publications (overnight and one, three, six and 12 months) until June 30, 2023, with the remainder of LIBOR publications to be phased out on schedule at the end of 2021. This delay is intended to allow most legacy U.S. dollar LIBOR contracts to mature before LIBOR experiences disruptions.

Abandonment of or modifications to LIBOR could lead to significant short-term and long-term uncertainty and market instability and the extent to which that may impact the Fund may vary depending on various factors, which include, but are not limited to, (i) existing fallback or termination provisions in individual contracts and (ii) whether, how, and when industry participants develop and adopt new successor reference rates (e.g., the Secured Overnight Financing Rate, which is intended to replace the U.S. dollar LIBOR) and/or fallbacks for both legacy and new instruments. In addition, the transition to a successor rate could potentially cause (i) increased volatility or illiquidity in markets for instruments that currently rely on LIBOR, particularly insofar as the documentation governing such instruments does not include fall back provisions addressing the transition from LIBOR, (ii) a reduction in the value of certain instruments held by the Fund, or (iii) reduced effectiveness of related Fund transactions, such as hedging. Any alternative reference rate may be an ineffective substitute resulting in prolonged adverse market conditions for the Fund. Not all existing LIBOR-based instruments may have alternative rate-setting provisions and there remains uncertainty regarding the willingness and ability of issuers to add alternative rate-setting provisions in certain existing instruments. It remains uncertain how such changes would be implemented and the effects such changes would have on the Fund, issuers of instruments in which the Fund invests and financial markets generally. Any such effects of the transition away from LIBOR, as well as other unforeseen effects, could result in losses to a Fund.

Leverage Risk

As of April 29, 2021, the Fund had a revolving credit facility with a financial institution. The Fund may seek to enhance the level of its current distributions to holders of Common Stock through the use of leverage. The Fund may use leverage directly at the Fund level. In an effort to mitigate the overall risk of leverage, the Fund does not intend to incur leverage that exceeds 33 ¹/₃% of the Fund’s Managed Assets immediately after Borrowings and/or issuances of Preferred Stock.

The Fund also may establish a standby credit facility in an amount up to 5% of Managed Assets as a temporary measure for purposes of making distributions to stockholders in order to maintain its favorable tax status as a regulated investment company. In addition, the Fund may borrow for temporary, emergency or other purposes as permitted under the 1940 Act. Any such indebtedness would be in addition to the combined direct and implicit leverage ratio of up to 33 ¹/₃% of the Fund’s Managed Assets.

The Fund will pay (and Common Stockholders will bear) any costs and expenses relating to the use of leverage by the Fund, to the extent the Fund bears such costs, which will result in a reduction in the net asset value of the Common Stock.

Leverage may result in greater volatility of the net asset value and market price of, and distributions on, the Common Stock because changes in the value of the Fund’s portfolio investments, including investments purchased with the proceeds from Borrowings or the issuance of Preferred Stock, if any, are borne entirely by Common Stockholders. Common Stock income may fall if the interest rate on Borrowings or the dividend rate on Preferred Stock rises, and may fluctuate as the interest rate on Borrowings or the dividend rate on Preferred Stock varies. So long as the Fund is able to realize a higher net return on its investment portfolio than the then-current cost of any leverage together with other related expenses, the effect of the leverage will be to cause Common Stockholders to realize higher current net investment income than if the Fund were not so leveraged. On the other hand, the Fund’s use of leverage will result in increased operating costs. Thus, to the extent that the then-current cost of any leverage, together with other related expenses, approaches the net return on the Fund’s investment portfolio, the benefit of leverage to Common Stockholders will be reduced, and if the then-current cost of any leverage together with related expenses were to exceed the net return on the Fund’s portfolio, the Fund’s leveraged capital structure would result in a lower rate of return to Common Stockholders than if the Fund were not so leveraged. There can be no assurance that the Fund’s leveraging strategy will be successful.

During periods when the Fund is using leverage through Borrowings or the issuance of Preferred Stock, the fees paid to LMPFA, Western Asset, and Western Asset Limited for advisory services will be higher than if the Fund did not use leverage because the fees paid will be calculated on the basis of the Fund’s Managed Assets, which includes the amount of Borrowings and any assets attributable to Preferred Stock. This means that LMPFA, Western Asset and Western Asset Limited may have a financial incentive to increase the Fund’s use of leverage.

Any decline in the net asset value of the Fund will be borne entirely by Common Stockholders. Therefore, if the market value of the Fund’s portfolio declines, the Fund’s use of leverage will result in a greater decrease in net asset value to Common Stockholders than if the Fund were not leveraged. Such greater net asset value decrease will also tend to cause a greater decline in the market price for the Common Stock.

48

Certain types of Borrowings may result in the Fund being subject to covenants in credit agreements relating to asset coverage or portfolio composition or otherwise. In addition, the terms of the credit agreements may also require that the Fund pledge some or all of its assets as collateral. In addition, the Fund may be subject to certain restrictions imposed by guidelines of one or more rating agencies which may issue ratings for commercial paper or notes issued by the Fund. Such restrictions may be more stringent than those imposed by the 1940 Act.

The current weakness in the financial markets, the residential and commercial mortgage markets and the economy could adversely affect one or more of the Fund’s potential lenders and could cause one or more of the Fund’s potential lenders to be unwilling or unable to provide the Fund with financing or to increase the costs of that financing. Current market conditions have affected different types of financing for mortgage-related assets to varying degrees, with some sources generally being unavailable, others being available but at a higher cost, while others are largely unaffected. For example, in the repurchase agreement market, non-agency RMBS have been more difficult to finance than agency RMBS. Repurchase agreement counterparties have generally increased haircuts, which are the percentages that represent how much the amount of the loan is less than the value of the collateral securing the loan. Repurchase agreement counterparties have taken these steps in order to compensate themselves for a perceived increased risk due to the illiquidity of the underlying collateral. In some cases, margin calls have forced borrowers to liquidate collateral in order to meet the capital requirements of these margin calls, resulting in losses.

The return on the Fund’s assets and cash available for distribution to Common Stockholders may be reduced to the extent that market conditions prevent the Fund from leveraging assets or cause the cost of the Fund’s financing to increase relative to the income that can be derived from the assets acquired. The Fund’s financing costs will reduce cash available for distributions to Common Stockholders. The Fund may not be able to meet its financing obligations and, to the extent that it cannot, it risks the loss of some or all of its assets to liquidation or sale to satisfy the obligations under its repurchase agreements. A decrease in the value of these assets may lead to margin calls which the Fund will have to satisfy. The Fund may not have the funds available to satisfy any such margin calls and may be forced to sell assets at significantly depressed prices due to market conditions or otherwise, which may result in losses. The satisfaction of such margin calls may reduce cash flow available for distribution to Common Stockholders. Any reduction in distributions to Common Stockholders may cause the value of the Fund’s Common Stock to decline.

ABS Risk

The Fund may invest up to 20% of its Managed Assets in non-mortgage related ABS. Investing in ABS entails various risks, including credit risks, liquidity risks, interest rate risks, market risks and legal risks. Credit risk is an important issue in ABS because of the significant credit risks inherent in the underlying collateral and because issuers are primarily private entities. The structure of an ABS and the terms of the investors’ interest in the collateral can vary widely depending on the type of collateral, the desires of investors and the use of credit enhancements. Although the basic elements of all ABS are similar, individual transactions can differ markedly in both structure and execution. Important determinants of the risk associated with issuing or holding the securities include the process by which principal and interest payments are allocated and distributed to investors, how credit losses affect the issuing vehicle and the return to investors in such ABS, whether collateral represents a fixed set of specific assets or accounts, whether the underlying collateral assets are revolving or closed-end, under what terms (including the maturity of the ABS itself) any remaining balance in the accounts may revert to the issuing entity and the extent to which the entity that is the actual source of the collateral assets is obligated to provide support to the issuing vehicle or to the investors in such ABS. The Fund may invest in ABS that are subordinate in right of payment and rank junior to other securities that are secured by or represent an ownership interest in the same pool of assets. In addition, many of the transactions in which such securities are issued have structural features that divert payments of interest and/or principal to more senior classes when the delinquency or loss experience of the pool exceeds certain levels. As a result, such securities have a higher risk of loss as a result of delinquencies or losses on the underlying assets.

49

Below Investment Grade (“High Yield” or “Junk”) Securities Risk

A significant portion of the Fund’s portfolio may consist of below investment grade securities. The Fund will invest a substantial portion of its assets in MBS that were originally rated AAA, but subsequently have been downgraded to below investment grade. As a result of being downgraded to below investment grade, these assets will be regarded as predominately speculative with respect to the issuer’s capacity to pay interest and repay principal. Lower grade securities may be particularly susceptible to economic downturns. It is likely that the current economic recession could further disrupt the market for such securities and may have an adverse impact on the value of such securities. In addition, it is likely that any such economic downturn could adversely affect the ability of the issuers of such securities to repay principal and pay interest thereon and increase the incidence of default for such securities.

Lower grade securities, though high yielding, are characterized by high risk. They may be subject to certain risks with respect to the issuing entity and to greater market fluctuations than certain lower yielding, higher rated securities. The retail secondary market for lower grade securities may be less liquid than that for higher rated securities. Adverse conditions could make it difficult at times to sell certain securities or could result in lower prices than those used in calculating the Fund’s net asset value. Because of the substantial risks associated with investments in lower grade securities, you could lose money on your investment in Common Stock, both in the short-term and the long-term.

Distressed Investments

The Fund will invest in distressed securities, which are securities and obligations of companies that are experiencing financial or business difficulties. Distressed investments may result in significant returns to the Fund, but also involve a substantial degree of risk. Among the risks inherent in distressed situations is the fact that it frequently may be difficult to obtain information as to the true condition of the securities being purchased. The market prices of distressed securities are also subject to abrupt and erratic market movements and above average price volatility, and the spread between the bid and asked prices of such securities may be greater than normally experienced.

The Fund intends to invest in distressed investments including non-performing and sub-performing RMBS and CMBS, many of which are not publicly traded and which may involve a substantial degree of risk. In certain periods, there may be little or no liquidity in the markets for these securities or instruments. In addition, the prices of such securities or instruments may be subject to periods of abrupt and erratic market movements and above-average price volatility. It may be more difficult to value such securities and the spread between the bid and asked prices of such securities may be greater than normally expected. If the Western Asset’s evaluation of the risks and anticipated outcome of an investment in a distressed security should prove incorrect, the Fund may lose a substantial portion or all of its investment.

Furthermore, investments in assets operating in workout modes or under Chapter 11 of the United States Bankruptcy Code, as amended, and other comparable bankruptcy laws may, in certain circumstances, be subject to certain additional potential liabilities that may exceed the value of the Fund’s original investment. For example, under certain circumstances, lenders who have inappropriately exercised control of the management and policies of a debtor may have their claims subordinated or disallowed or counterclaims may be filed and lenders may be found liable for damages suffered by various parties as a result of such actions. In addition, under certain circumstances, payments to the Fund and distributions by the Fund to its investors may be reclaimed if any such payment or distribution is later determined to have been a fraudulent conveyance or a preferential payment.

The Fund is not limited in its ability to invest in distressed investments.

Credit Risk Associated with Originators and Servicers of Residential and Commercial Mortgage Loans

A number of originators and servicers of residential and commercial mortgage loans, including some of the largest originators and servicers in the residential and commercial mortgage loan market, have experienced serious financial difficulties, including some that are now subject to federal insolvency proceedings. These difficulties have resulted from many factors, including increased competition among originators for borrowers, decreased originations by such originators of mortgage loans and increased delinquencies and defaults on such mortgage loans, as well as from increases in claims for repurchases of mortgage loans previously sold by them under agreements that

50

require repurchase in the event of breaches of representations regarding loan quality and characteristics. Such difficulties may affect the performance of non-agency RMBS and CMBS backed by mortgage loans. Furthermore, the inability of the originator to repurchase such mortgage loans in the event of loan representation breaches or the servicer to repurchase such mortgage loans upon a breach of its servicing obligations also may affect the performance of related non-agency RMBS and CMBS. Delinquencies and losses on, and, in some cases, claims for repurchase by the originator of, mortgage loans originated by some mortgage lenders have increased as a result of inadequate underwriting procedures and policies, including inadequate due diligence, failure to comply with predatory and other lending laws and, particularly in the case of any “no documentation” or “limited documentation” mortgage loans that may support non-agency RMBS, inadequate verification of income and employment history. Delinquencies and losses on, and claims for repurchase of, mortgage loans originated by some mortgage lenders have also resulted from fraudulent activities of borrowers, lenders, appraisers, and other residential mortgage industry participants such as mortgage brokers, including misstatements of income and employment history, identity theft and overstatements of the appraised value of mortgaged properties. Many of these originators and servicers are very highly leveraged. These difficulties may also increase the chances that these entities may default on their warehousing or other credit lines or become insolvent or bankrupt and thereby increase the likelihood that repurchase obligations will not be fulfilled and the potential for loss to holders of non-agency RMBS, CMBS and subordinated security holders.

The servicers of non-agency RMBS and CMBS are often the same entities as, or affiliates of, the originators of these mortgage loans. Accordingly, the financial risks relating to originators of non-agency RMBS and CMBS described immediately above also may affect the servicing of non-agency RMBS and CMBS. In the case of such servicers, and other servicers, financial difficulties may have a negative effect on the ability of servicers to pursue collection on mortgage loans that are experiencing increased delinquencies and defaults and to maximize recoveries on sale of underlying properties following foreclosure.

Non-agency RMBS and CMBS typically provide that the servicer is required to make advances in respect of delinquent mortgage loans. However, servicers experiencing financial difficulties may not be able to perform these obligations or obligations that they may have to other parties of transactions involving these securities. Like originators, these entities are typically very highly leveraged. Such difficulties may cause servicers to default under their financing arrangements. In certain cases, such entities may be forced to seek bankruptcy protection. Due to the application of the provisions of bankruptcy law, servicers who have sought bankruptcy protection may not be required to advance such amounts. Even if a servicer were able to advance amounts in respect of delinquent mortgage loans, its obligation to make such advances may be limited to the extent that it does not expect to recover such advances due to the deteriorating credit of the delinquent mortgage loans or declining value of the related mortgaged properties. Moreover, servicers may overadvance against a particular mortgage loan or charge too many costs of resolution or foreclosure of a mortgage loan to a securitization, which could increase the potential losses to holders of non-agency RMBS and CMBS. In such transactions, a servicer’s obligation to make such advances may also be limited to the amount of its servicing fee. In addition, if an issue of non-agency RMBS and CMBS provides for interest on advances made by the servicer, in the event that foreclosure proceeds or payments by borrowers are not sufficient to cover such interest, such interest will be paid to the servicer from available collections or other mortgage income, thereby reducing distributions made on the non-agency RMBS and CMBS and, in the case of senior-subordinated non-agency RMBS and CMBS described below, first from distributions that would otherwise be made on the most subordinated non-agency RMBS and CMBS of such issue. Any such financial difficulties may increase the possibility of a servicer termination and the need for a transfer of servicing and any such liabilities or inability to assess such liabilities may increase the difficulties and costs in affecting such transfer and the potential loss, through the allocation of such increased cost of such transfer, to subordinated security holders.

There can be no assurance that originators and servicers of mortgage loans will not continue to experience serious financial difficulties or experience such difficulties in the future, including becoming subject to bankruptcy or insolvency proceedings, or that underwriting procedures and policies and protections against fraud will be sufficient in the future to prevent such financial difficulties or significant levels of default or delinquency on mortgage loans. Because the recent financial difficulties experienced by such originators and services is unprecedented and unpredictable, the past performance of the residential and commercial mortgage loans originated and serviced by them (and the corresponding performance of the related non-agency RMBS and CMBS) is not a reliable indicator of the future performance of such residential mortgage loans (or the related non-agency RMBS and CMBS).

Subprime Mortgage Market Risk

The residential mortgage market in the United States has experienced difficulties that may adversely affect the performance and market value of certain mortgages and mortgage-related securities. Delinquencies and losses on residential mortgage loans (especially subprime and second-line mortgage loans) generally have increased and may continue to increase, and a decline in or flattening of housing values (as has been experienced and may continue to be experienced in many housing markets) may exacerbate such delinquencies and losses. Borrowers with adjustable rate mortgage loans are more sensitive to changes in interest rates, which affect their monthly mortgage payments, and may be unable to secure replacement mortgages at comparably low interest rates. Also, a number of residential mortgage loan originators have experienced serious financial difficulties or bankruptcy. Largely due to the foregoing, reduced investor demand for mortgage loans and mortgage-related securities and increased investor yield requirements have caused limited liquidity in the secondary market for mortgage-related securities, which can adversely affect the market value of mortgage-related securities. It is possible that such limited liquidity in such secondary markets could continue or worsen.

The Fund may acquire non-agency RMBS backed by collateral pools of mortgage loans that have been originated using underwriting standards that are less restrictive than those used in underwriting “prime mortgage loans” and “Alt-A mortgage loans.” These lower standards include mortgage loans made to borrowers having imperfect or impaired credit histories, mortgage loans where the amount of the loan at origination is 80% or more of the value of the mortgage property, mortgage loans made to borrowers with low credit scores, mortgage loans made to borrowers who have other debt that represents a large portion of their income and mortgage loans made to borrowers whose income is not required to be disclosed or verified. Due to economic conditions, including increased interest rates and lower home prices, as well as aggressive lending practices, subprime mortgage loans have in recent periods experienced increased rates of delinquency, foreclosure, bankruptcy and loss, and they are likely to continue to experience delinquency, foreclosure, bankruptcy and loss rates that are higher, and that may be substantially higher, than those experienced by mortgage loans underwritten in a more traditional manner. Thus, because of the higher delinquency rates and losses associated with subprime mortgage loans, the performance of non-agency RMBS backed by subprime mortgage loans that the Fund may acquire could be correspondingly adversely affected, which could adversely impact the Fund’s results of operations, financial condition and business.

If the economy of the United States further deteriorates, the incidence of mortgage foreclosures, especially subprime mortgages, may continue to increase, which may adversely affect the value of any MBS owned by the Fund. The U.S. Congress and various government regulatory authorities have discussed the possibility of restructuring mortgages and imposing forbearance requirements on defaulted mortgages. Neither LMPFA nor Western Asset can predict the form any such modifications, forbearance or related regulations might take, and these regulations may adversely affect the value of MBS owned by the Fund.

Risks Relating to Investments in Mortgage Whole Loans

Credit Risk Associated With Investments in Mortgage Whole Loans

The holder of residential and commercial mortgages assumes the risk that the related borrowers may default on their obligations to make full and timely payments of principal and interest. In general, these investments carry greater investment risk than agency MBS/CMBS because the former are not guaranteed as to principal or interest by the U.S. Government, any federal agency or any federally chartered corporation. As a result, a mortgage whole loan is directly exposed to losses resulting from default and foreclosure. Therefore, the value of the underlying property, the creditworthiness and financial position of the borrower, and the priority and enforceability of the lien are each of great importance. Whether or not Franklin Templeton, Western Asset or their affiliates have participated in the negotiation of the terms of any such mortgages, there can be no assurance as to the adequacy of the protection of the terms of the loan, including the validity or enforceability of the loan and the maintenance of the anticipated priority and perfection of the applicable security interests. Furthermore, claims may be asserted that might interfere with enforcement of the rights of the Fund. In the event of a foreclosure, the Fund may assume direct ownership of the underlying real estate. The liquidation proceeds upon sale of such real estate may not be sufficient to recover the Fund’s cost basis in the loan, resulting in a loss to the Fund. Any costs or delays involved in the effectuation of a foreclosure of the loan or a liquidation of the underlying property will further reduce the proceeds and thus increase the loss.

52

Higher-than-expected rates of default and/or higher-than-expected loss severities on these investments could adversely affect the value of these assets. Accordingly, defaults in the payment of principal and/or interest on the Fund’s residential and commercial whole loans would likely result in the Fund incurring losses of income from, and/or losses in market value relating to, these assets, which could materially adversely affect the Fund’s results of operations.

Holders of residential and commercial whole loans are subject to the risk that the related borrowers may default or have defaulted on their obligations to make full and timely payments of principal and interest. A number of factors impact a borrower’s ability to repay including, among other things, changes in employment status, changes in interest rates or the availability of credit, and changes in real estate values. In addition to the credit risk associated with these assets, residential and commercial whole loans are less liquid than certain of the Fund’s other credit sensitive assets, which may make them more difficult to dispose of if the need or desire arises. If actual results are different from the Fund’s assumptions in determining the prices paid to acquire such loans, particularly if the market value of the underlying properties decreases significantly subsequent to purchase, we may incur significant losses, which could materially adversely affect the Fund’s results.

Servicing-Related Risks of Mortgage Whole Loans

We rely on third-party servicers to service and manage the mortgages underlying the Fund’s loan portfolio. The ultimate returns generated by these investments may depend on the quality of the servicer. If a servicer is not vigilant in seeing that borrowers make their required monthly payments, borrowers may be less likely to make these payments, resulting in a higher frequency of default. If a servicer takes longer to liquidate non-performing mortgages, the Fund’s losses related to those loans may be higher than originally anticipated. Any failure by servicers to service these mortgages and/or to competently manage and dispose of REO properties could negatively impact the value of these investments and the Fund’s financial performance. In addition, while we have contracted with third-party servicers to carry out the actual servicing of the loans (including all direct interface with the borrowers), for loans that we purchase together with the related servicing rights, we are nevertheless ultimately responsible, vis-à-vis the borrowers and state and federal regulators, for ensuring that the loans are serviced in accordance with the terms of the related notes and mortgages and applicable law and regulation. In light of the current regulatory environment, such exposure could be significant even though we might have contractual claims against the Fund’s servicers for any failure to service the loans to the required standard.

The foreclosure process, especially in judicial foreclosure states such as New York, Florida and New Jersey, can be lengthy and expensive, and the delays and costs involved in completing a foreclosure, and then subsequently liquidating the REO property through sale, may materially increase any related loss. In addition, at such time as title is taken to a foreclosed property, it may require more extensive rehabilitation than we estimated at acquisition. Thus, a material amount of foreclosed residential mortgage loans, particularly in the states mentioned above, could result in significant losses in the Fund’s residential and commercial whole loan portfolio and could materially adversely affect the Fund’s results of operations.

Prepayment Risk Associated With Investments in Mortgage Whole Loans

The residential and commercial whole loans we acquire are backed by pools of residential and commercial mortgage loans. We receive payments, generally, from the payments that are made on these underlying residential and commercial mortgage loans. While commercial mortgages frequently include limitations on the ability of the borrower to prepay, Residential and Commercial mortgages generally do not. When borrowers prepay their residential and commercial mortgage loans at rates that are faster than expected, the net result is prepayments that are faster than expected on the residential and commercial whole loans. These faster than expected payments may adversely affect the Fund’s profitability.

We may purchase residential and commercial whole loans that have a higher interest rate than the then prevailing market interest rate. In exchange for this higher interest rate, we may pay a premium to par value to acquire the asset. In accordance with accounting rules, we amortize this premium over the expected term of the asset based on the Fund’s prepayment assumptions. If the asset is prepaid in whole or in part at a faster than expected rate, however, we must expense all or a part of the remaining unamortized portion of the premium that was paid at the time of the purchase, which will adversely affect the Fund’s profitability.

53

Prepayment rates generally increase when interest rates fall and decrease when interest rates rise, but changes in prepayment rates are difficult to predict. House price appreciation, while increasing the value of the collateral underlying the Fund’s residential and commercial whole loans, may increase prepayment rates as borrowers may be able to refinance at more favorable terms. Prepayments can also occur when borrowers default on their residential and commercial mortgages and the mortgages are prepaid from the proceeds of a foreclosure sale of the property (an involuntary prepayment), or when borrowers sell the property and use the sale proceeds to prepay the mortgage as part of a physical relocation. Prepayment rates also may be affected by conditions in the housing and financial markets, increasing defaults on Residential and Commercial mortgage loans, which could lead to an acceleration of the payment of the related principal, general economic conditions and the relative interest rates on fixed-rate mortgages and ARMs. While we seek to manage prepayment risk, in selecting residential and commercial whole loans investments we must balance prepayment risk against other risks, the potential returns of each investment and the cost of hedging the Fund’s risks. No strategy can completely insulate us from prepayment or other such risks, and we may deliberately retain exposure to prepayment or other risks.

In addition, a decrease in prepayment rates may adversely affect the Fund’s profitability. When borrowers prepay their residential and commercial mortgage loans at slower than expected rates, prepayments on the residential and commercial whole loans may be slower than expected. These slower than expected payments may adversely affect the Fund’s profitability. We may purchase residential and commercial whole loans that have a lower interest rate than the then prevailing market interest rate. In exchange for this lower interest rate, we may pay a discount to par value to acquire the asset. In accordance with accounting rules, we accrete this discount over the expected term of the asset based on the Fund’s prepayment assumptions. If the asset is prepaid at a slower than expected rate, however, we must accrete the remaining portion of the discount at a slower than expected rate. This will extend the expected life of the asset and result in a lower than expected yield on assets purchased at a discount to par.

Geographic Concentration Risk Associated With Residential and Commercial Whole Loans

The Fund’s performance depends on the economic conditions in markets in which the properties securing the mortgage loans underlying the Fund’s investments are concentrated. As of April 29, 2021, a substantial portion of the appropriate assets for this portfolio had underlying properties in California. The Fund’s financial condition, results of operations, the market price of the Fund’s common stock and the Fund’s ability to make distributions to the Fund’s stockholders could be materially and adversely affected by this geographic concentration if market conditions, such as an oversupply of space or a reduction in demand for real estate in an area, deteriorate in California. Moreover, due to the geographic concentration of properties securing the mortgages underlying the Fund’s investments, the Fund may be disproportionately affected by general risks such as natural disasters, including major wildfires, floods and earthquakes, severe or inclement weather, and acts of terrorism should such developments occur in or near the markets in California in which such properties are located.

Other Risks Associated with Mortgage Whole Loans

Mortgage whole loans have risks above and beyond those discussed above. For example, mortgage whole loans are subject to “special hazard” risk (property damage caused by hazards, such as earthquakes or environmental hazards, not covered by standard property insurance policies) and to bankruptcy risk (reduction in a borrower’s mortgage debt by a bankruptcy court). In addition, claims may be assessed against the Fund on account of its position as mortgage holder or property owner, including responsibility for tax payments, environmental hazards and other liabilities.

Tax Risks

To qualify for the favorable U.S. federal income tax treatment generally accorded to regulated investment companies, among other things, the Fund must derive in each taxable year at least 90% of its gross income from certain prescribed sources and satisfy certain distribution and asset diversification requirements. If for any taxable year the Fund does not qualify as a regulated investment company, all of its taxable income (including its net capital gain) would be subject to tax at regular corporate rates without any deduction for distributions to stockholders, and such distributions would be taxable as ordinary dividends to the extent of the Fund’s current and accumulated earnings and profits.

54

Risk of Taxable Income in Excess of Economic Income. The Fund expects to acquire debt instruments in the secondary market for less than their stated redemption price at maturity. The discount at which such debt instruments are acquired may reflect doubts about their ultimate collectability rather than current market interest rates. The amount of such discount will nevertheless generally be treated as “market discount” for U.S. federal income tax purposes. Market discount on a debt instrument accrues ratably on a daily basis, unless an election is made to accrue market discount on the basis of the constant yield to maturity of the debt instrument, based generally on the assumption that all future payments on the debt instrument will be made. Absent an election to accrue currently, accrued market discount is reported as income when, and to the extent that, any payment of principal of the debt instrument is made. Payments on residential mortgage loans are ordinarily made monthly, and include both principal and interest, and consequently accrued market discount may have to be included in income each month as if the debt instrument were assured of ultimately being collected in full.

Similarly, many of the debt instruments (including MBS) that the Fund purchases will likely have been issued with original issue discount (“OID”), which discount might reflect doubt as to whether the entire principal amount of such debt instruments will ultimately prove to be collectible. The Fund will be required to report such OID based on a constant yield method and income will be accrued and be currently taxable based on the assumption that all future projected payments due on such debt instruments will be made.

Finally, in the event that any debt instruments (including MBS) acquired by the Fund are delinquent as to mandatory principal and interest payments, or in the event payments with respect to a particular debt instrument are not made when due, the Fund may nonetheless be required to continue to recognize the unpaid interest as taxable income as it accrues, despite doubt as to its ultimate collectability. Similarly, the Fund may be required to accrue interest income with respect to subordinate MBS at the stated rate regardless of whether corresponding cash payments are received or are ultimately collectible.

Status as Regulated Investment Company. As described under the heading “Certain United States Federal Income Tax Considerations,” the Fund must satisfy, among other requirements, an asset diversification test in order to qualify as a regulated investment company under Subchapter M of the Code. Under that test, the Fund must diversify its holdings so that, at the end of each quarter of each taxable year, (i) at least 50% of the value of the Fund’s assets is represented by cash and cash items (including receivables), U.S. government securities, the securities of other regulated investment companies and other securities, with such other securities of any one issuer limited for the purposes of this calculation to an amount not greater than 5% of the value of the Fund’s total assets and not greater than 10% of the outstanding voting securities of such issuer, and (ii) not more than 25% of the value of its total assets is invested in the securities (other than U.S. government securities or the securities of other regulated investment companies) of a single issuer, or two or more issuers that the Fund controls and are engaged in the same, similar or related trades or businesses, or the securities of one or more qualified publicly traded partnerships.

If the Fund fails to satisfy as of the close of any quarter the asset diversification test referred to in the preceding paragraph, it will have 30 days to cure the failure by, for example, selling securities that are the source of the violation. Other cure provisions are available in the Code for a failure to satisfy the asset diversification test, but any such cure provision may involve the payment of a penalty excise tax. If the Fund fails to cure an asset diversification violation, it may lose its status as a regulated investment company under the Code. In that case, all of its taxable income would be subject to U.S. federal income tax at regular corporate rates without any deduction for distributions to stockholders. In addition, all distributions (including distributions of net capital gain) would be taxed to the Fund’s Common Stockholders as ordinary dividend income to the extent of the Fund’s current and accumulated earnings and profits. Accordingly, disqualification as a regulated investment company could have a material adverse effect on the value of the Fund’s Common Stock and the amount of Fund distributions.

Risks Associated with the Fund’s Ability To Satisfy Regulated Investment Company Distribution Requirements. The Fund generally must distribute annually at least 90% of its taxable income, excluding any net capital gain, in order to maintain its qualification as a regulated investment company for U.S. federal income tax purposes. To the extent that the Fund satisfies this distribution requirement, but distributes less than 100% of its taxable income and net capital gain, the Fund will be subject to U.S. federal corporate income tax on the Fund’s undistributed taxable income. In addition, the Fund will be subject to a 4% nondeductible excise tax if the actual amount that the Fund distributes to its stockholders in a calendar year is less than a minimum amount specified

55

under U.S. federal income tax laws. The Fund intends to make distributions to its stockholders to comply with the requirements of the Code and to avoid paying U.S. federal income taxes and, if practicable, excise taxes, on undistributed taxable income. However, differences in timing between the recognition of taxable income and the actual receipt of cash could require the Fund to sell assets (including (i) cash, (ii) bank deposits, (iii) Treasury securities with maturities of not more than 90 calendar days, (iv) money market mutual funds that (a) are registered with the the SEC and regulated under Rule 2a-7 promulgated under the 1940 Act and (b) invest exclusively in direct obligations of the United States or obligations the prompt payment of the principal of and interest on which is unconditionally guaranteed by the United States, (v) repurchase agreements secured by Treasury securities (if permitted by the Treasury) and (vi) any other investment approved by the Treasury in writing (collectively, “Temporary Investments”)) or borrow funds on a short-term or long-term basis or issue cash-stock dividends (described below) to meet the distribution requirements of the Code.

The Fund may find it difficult or impossible to meet distribution requirements in certain circumstances. Due to the nature of the assets in which the Fund intends to invest, the Fund’s taxable income may exceed the Fund’s net income as determined based on generally accepted accounting principles (“GAAP”) because, for example, realized capital losses will be deducted in determining the Fund’s GAAP net income but may not be deductible in computing the Fund’s taxable income required to be distributed. In addition, the Fund may invest in assets, including debt instruments requiring the Fund to accrue OID, that generate taxable income (referred to as “phantom income”) in excess of economic income or in advance of the corresponding cash flow from the assets. In addition, if the debt instruments provide for “payment-in-kind” or PIK interest, the Fund may recognize OID for federal income tax purposes. Moreover, the Fund may acquire distressed debt investments that are subsequently modified by agreement with the borrower. If the amendments to the outstanding debt are “significant modifications” under the applicable Treasury regulations, the modified debt may be considered to have been reissued to the Fund in a debt-for-debt exchange with the borrower. In that event, if the debt is considered to be “publicly traded” for federal income tax purposes, the modified debt in the hands of the Fund may be considered to have been issued with OID to the extent the fair-market value of the modified debt is less than the principal amount of the outstanding debt. Also, certain previously modified debt that the Fund acquires in the secondary market may be considered to have been issued with OID at the time it was modified. In general, the Fund will be required to accrue OID on a debt instrument as taxable income in accordance with applicable federal income tax rules even though no cash payments may be received on such debt instrument. In the event a borrower with respect to a particular debt instrument encounters financial difficulty rendering it unable to pay stated interest as due, the Fund may nonetheless be required to continue to recognize the unpaid interest as taxable income. Similarly, the Fund may be required to accrue interest income with respect to subordinate MBS at the stated rate regardless of when their corresponding cash payments are received. Further, the Fund may invest in assets that accrue market discount income, which may result in the recognition of taxable income in excess of the Fund’s economic gain in certain situations or the deferral of a portion of the Fund’s interest deduction paid on debt incurred to acquire or carry such assets.

Due to each of these potential timing differences between income recognition or expense deduction and cash receipts or disbursements, there is a significant risk that the Fund may have substantial taxable income in excess of cash available for distribution. To satisfy its distribution requirements, the Fund may borrow on unfavorable terms or distribute amounts that would otherwise be invested in future acquisitions, capital expenditures or repayment of debt. In addition, the Fund may make distributions in its Common Stock to satisfy the distribution requirements necessary to maintain the Fund’s status as a regulated investment company for U.S. federal income tax purposes and to avoid U.S. federal income and excise taxes, but no assurances can be given in this regard. Moreover, if the Fund’s only feasible alternative were to make a taxable distribution of the Fund’s Common Stock to comply with the regulated investment company distribution requirements for any taxable year and the value of the Fund’s Common Stock was not sufficient at such time to make a distribution to its Common Stockholders in an amount at least equal to the minimum amount required to comply with such regulated investment company distribution requirements, the Fund would generally fail to qualify as a regulated investment company for such taxable year.

Despite undertaking the efforts mentioned in the previous paragraph, the Fund may not be able to distribute the amounts necessary to satisfy the distribution requirements necessary to maintain its regulated investment company status for U.S. federal income taxes and to avoid U.S. federal income and excise taxes. If the Fund were unable to satisfy the 90% distribution requirement or otherwise were to fail to qualify as a regulated investment company in any year, material adverse tax consequences would result to investors. The Fund would be taxed in the same manner as an ordinary corporation and distributions to the Fund’s Common Stockholders would not be deductible by the Fund in computing its taxable income. To qualify again to be taxed as a regulated investment company in a subsequent year, the Fund would be required to distribute to its Common Stockholders its earnings and profits attributable to non-regulated investment company years reduced by an interest charge on 50% of such earnings and profits payable by the Fund to the Internal Revenue Service (“IRS”). In addition, if the Fund failed to

56

qualify as a regulated investment company for a period greater than two taxable years, then the Fund would be required to elect to recognize and pay tax on any net built-in gain (the excess of aggregate gain, including items of income, over aggregate loss that would have been realized if the Fund had been liquidated) or, alternatively, be subject to taxation on such built-in gain recognized for a period of 5 years, in order to qualify as a regulated investment company in a subsequent year.

Cash/Stock Dividend Risks. The Fund may distribute taxable dividends that are payable in cash and Common Stock at the election of each Common Stockholder. Under IRS Revenue Procedure 2017-45, up to 80% of any such taxable dividend could be payable in the Fund’s Common Stock with the 20% or greater balance paid in cash. Common Stockholders receiving such dividends will be required to include the full amount of the dividend as taxable income to the extent of the Fund’s current and accumulated earnings and profits for federal income tax purposes. As a result, Common Stockholders may be required to pay federal income taxes with respect to such dividends in excess of the cash dividends received. If a Common Stockholder sells the Common Stock that it receives as a dividend in order to pay this tax, the sales proceeds may be less than the amount included in income with respect to the dividend, depending on the market price of the Fund’s Common Stock at the time of the sale. Furthermore, with respect to non-U.S. Common Stockholders, the Fund may be required to withhold U.S. tax with respect to such dividends, including in respect of all or a portion of such dividend that is payable in Common Stock. In addition, if a significant number of the Fund’s Common Stockholders determine to sell shares of the Fund’s Common Stock in order to pay taxes owed on dividends, it may put downward pressure on the trading price of the Fund’s Common Stock. It is unclear whether and to what extent the Fund will be able to pay taxable dividends in cash and Common Stock (whether pursuant to Revenue Procedure 2017-45 or otherwise).

Government Intervention in Financial Markets Risk

United States federal and state governments and foreign governments, their regulatory agencies or self-regulatory organizations may take actions designed to support certain financial institutions and segments of the financial markets that have experienced extreme volatility, and in some cases a lack of liquidity, that affect the regulation of the securities in which the Fund invests, or the issuers of such securities, in ways that are unforeseeable issuers of corporate fixed income securities might seek protection under the bankruptcy laws. Legislation or regulation may also change the way in which the Fund itself is regulated. Such legislation or regulation could limit or preclude the Fund’s ability to achieve its investment objectives. Western Asset monitors developments and seeks to manage the Fund’s portfolio in a manner consistent with achieving the Fund’s investment objective, but there can be no assurance that it will be successful in doing so.

Currency Risks

If the Fund invests directly in foreign (non-U.S.) currencies or in securities that trade in, and receive revenues in, foreign (non-U.S.) currencies, or in derivatives that provide exposure to foreign (non-U.S.) currencies, it will be subject to the risk that those currencies will decline in value relative to the U.S. dollar, or, in the case of hedging positions intended to protect the Fund from decline in the value of foreign (non-U.S.) currencies, that the U.S. dollar will decline in value relative to the currency being hedged. Currency rates in foreign countries may fluctuate significantly over short periods of time for a number of reasons, including changes in interest rates, intervention (or the failure to intervene) by U.S. or foreign governments, central banks or supranational entities such as the International Monetary Fund, or by the imposition of currency controls or other political developments in the United States or abroad. As a result, the Fund’s investments in foreign currency denominated securities may reduce the returns of the Fund. While certain of the Fund’s non-U.S. dollar-denominated securities may be hedged into U.S. dollars, hedging may not alleviate all currency risks. See “—Derivatives Risk.”

Expedited Transactions

Investment analyses and decisions by LMPFA and Western Asset may frequently be required to be undertaken on an expedited basis to take advantage of investment opportunities. In such cases, the information available to LMPFA or Western Asset at the time of an investment decision may be limited, and LMPFA and Western Asset may not have access to detailed information regarding the investment opportunity. Therefore, no assurance can be given that LMPFA or Western Asset will have knowledge of all circumstances that may adversely affect an investment.

57

Extension Risk

Extension, or slower prepayments of the underlying mortgage loans, would extend the time it would take to receive cash flows and would generally compress the yield on non-agency RMBS and CMBS. Rising interest rates can cause the average maturity of the Fund to lengthen due to a drop in mortgage prepayments. This will increase both the sensitivity to rising interest rates and the potential for price declines of the Fund.

“Widening” Risk

The prices of non-agency RMBS or CMBS may decline substantially, for reasons that may not be attributable to any of the other risks described in this prospectus. In particular, purchasing assets at what may appear to be “undervalued” levels is no guarantee that these assets will not be trading at even more “undervalued” levels at a time of valuation or at the time of sale. It may not be possible to predict, or to protect against, such “spread widening” risk.

Management Risk and Reliance on Key Personnel

The Fund is subject to management risk because it is an actively managed investment portfolio. Western Asset and each individual portfolio manager may not be successful in selecting the best performing securities or investment techniques, and the Fund’s performance may lag behind that of similar funds. The Fund depends upon the diligence and skill of the portfolio managers, who evaluate, negotiate, structure and monitor its investments. These individuals do not have long-term employment contracts with Western Asset, although they do have equity interests and other financial incentives to remain with the Western Asset. The Fund also depends on the senior management of LMPFA, and the departure of any of the senior management of LMPFA could have a material adverse effect on the Fund’s ability to achieve its investment objectives. In addition, there is no guarantee that the Western Asset will remain our investment adviser.

Credit Crisis Liquidity and Volatility Risk

The markets for credit instruments, including MBS, have experienced periods of extreme illiquidity and volatility. General market uncertainty and consequent repricing risk have led to market imbalances of sellers and buyers, which in turn have resulted in significant valuation uncertainties in a variety of MBS. These conditions resulted, and in many cases continue to result in, greater volatility, less liquidity, widening credit spreads and a lack of price transparency, with many MBS remaining illiquid and of uncertain value. These market conditions may make valuation of some of the Fund’s MBS uncertain and/or result in sudden and significant valuation increases or declines in its holdings. A significant decline in the value of the Fund’s portfolio would likely result in a significant decline in the value of your investment in Common Stock.

The debt and equity capital markets in the United States have been negatively impacted by significant write-offs in the financial services sector relating to subprime mortgages and the re-pricing of credit risk in the broadly syndicated market, among other things. These events, along with the deterioration of the housing market and the failure of major financial institutions, have led to worsening general economic conditions, which have materially and adversely impacted the broader financial and credit markets and have reduced the availability of debt and equity capital for the market as a whole and financial firms in particular. These developments may increase the volatility of the value of securities owned by the Fund and also may make it more difficult for the Fund to accurately value securities or to sell securities on a timely basis. These developments have adversely affected the broader economy, and may continue to do so, which in turn may adversely affect the ability of issuers of securities owned by the Fund to make payments of principal and interest when due, lead to lower credit ratings and increase defaults. Such developments could, in turn, reduce the value of securities owned by the Fund and adversely affect the net asset value of the Fund. In addition, the prolonged continuation or further deterioration of current market conditions could adversely impact the Fund’s portfolio.

58

Investment Focus

The Fund invests a substantial portion of its assets in MBS and mortgage whole loans. As a result, the Fund will be affected to a greater degree by events affecting the MBS and mortgage whole loan markets, than if it invested in a broader array of securities, and such impact could be considerably greater than if it did not focus its investments to such an extent, particularly as a result of the leveraged nature of its investments. Such restrictions on the type of securities in which the Fund may invest may adversely affect the Fund’s ability to achieve its investment objectives.

The Fund employs a variety of proprietary risk analytics and risk management tools in connection with making and monitoring portfolio investments. Prospective investors should be aware that no risk management or portfolio analytics system is fail-safe, and no assurance can be given that risk frameworks employed by either LMPFA and/or Western Asset (e.g., stop-win, stop-loss, Sharpe Ratios, loss limits, value-at-risk or any other methodology now known or later developed) will achieve their objectives and prevent or otherwise limit substantial losses. No assurance can be given that the risk management systems and techniques or pricing models will accurately predict future trading patterns or the manner in which investments are priced in financial markets in the future. In addition, certain risk management tools may rely on certain assumptions (e.g., historical interest rates, anticipated rate trends) and such assumptions may prove incorrect.

Competition for Investment Opportunities

Identifying, completing and realizing attractive portfolio investments is competitive and involves a high degree of uncertainty. The Fund’s profitability depends, in large part, on its ability to acquire target assets at attractive prices. In acquiring its target assets, the Fund will compete with a variety of institutional investors, including specialty finance companies, public and private funds (including other funds managed by LMPFA or Western Asset), commercial and investment banks, commercial finance and insurance companies and other financial institutions. Many of the Fund’s competitors are substantially larger and have considerably greater financial, technical, marketing and other resources than does the Fund. Some competitors may have a lower cost of funds and access to funding sources that may not be available to the Fund, such as funding from the U.S. government, if the Fund is not eligible to participate in certain programs established by the U.S. government. In addition, some of the Fund’s competitors may have higher risk tolerances or different risk assessments, which could allow them to consider a wider variety of investments and establish more relationships than the Fund. Furthermore, competition for investments in the Fund’s target assets may lead to the price of such assets increasing, which may further limit the Fund’s ability to generate desired returns. The Fund cannot assure you that the competitive pressures it faces will not have a material adverse effect on its business, financial condition and results of operations. Also, as a result of this competition, desirable investments in the Fund’s target assets may be limited in the future and the Fund may not be able to take advantage of attractive investment opportunities from time to time, as the Fund can provide no assurance that it will be able to identify and make investments that are consistent with its investment objectives. Additional third-party managed investment funds with similar objectives may be formed in the future. Given the foregoing, it is possible that competition for appropriate portfolio investments may increase, thus reducing the number of attractive portfolio investment opportunities available to the Fund and may adversely affect the terms upon which investments can be made. There can be no assurance that the Fund will be able to locate, consummate and exit investments that satisfy its investment objective, or that it will be able to invest the net proceeds from this offering in MBS to the extent necessary to achieve its investment objectives.

Inflation/Deflation Risk

Inflation risk is the risk that the value of certain assets or income from the Fund’s investments will be worth less in the future as inflation decreases the value of money. As inflation increases, the real value of the Common Stock and distributions on the Common Stock can decline. In addition, during any periods of rising inflation, the dividend rates or borrowing costs associated with the Fund’s use of leverage would likely increase, which would tend to further reduce returns to stockholders. Deflation risk is the risk that prices throughout the economy decline over time—the opposite of inflation. Deflation may have an adverse effect on the creditworthiness of issuers and may make issuer defaults more likely, which may result in a decline in the value of the Fund’s portfolio.

59

Reinvestment Risk

Reinvestment risk is the risk that income from the Fund’s portfolio will decline if and when the Fund invests the proceeds from matured, traded or called bonds at market interest rates that are below the portfolio’s current earnings rate. A decline in income could affect the market price of Common Stock or your overall returns.

Reverse Repurchase Agreements Risk

The Fund’s use of reverse repurchase agreements involves many of the same risks involved in the Fund’s use of leverage, as the proceeds from reverse repurchase agreements generally will be invested in additional securities. There is a risk that the market value of the securities acquired in the reverse repurchase agreement may decline below the price of the securities that the Fund has sold but remains obligated to repurchase. In addition, there is a risk that the market value of the securities retained by the Fund may decline. If the buyer of securities under a reverse repurchase agreement were to file for bankruptcy or experience insolvency, the Fund may be adversely affected. Also, in entering into reverse repurchase agreements, the Fund would bear the risk of loss to the extent that the proceeds of the reverse repurchase agreement are less than the value of the underlying securities. In addition, due to the interest costs associated with reverse repurchase agreements transactions, the Fund’s net asset value will decline, and, in some cases, the Fund may be worse off than if it had not used such instruments.

Repurchase Agreements Risk

Subject to its investment objectives and policies, the Fund may invest in repurchase agreements for investment purposes. Repurchase agreements typically involve the acquisition by the Fund of debt securities from a selling financial institution such as a bank, savings and loan association or broker-dealer. The agreement provides that the Fund will sell the securities back to the institution at a fixed time in the future. The Fund does not bear the risk of a decline in the value of the underlying security unless the seller defaults under its repurchase obligation. In the event of the bankruptcy or other default of a seller of a repurchase agreement, the Fund could experience both delays in liquidating the underlying securities and losses, including (1) possible decline in the value of the underlying security during the period in which the Fund seeks to enforce its rights thereto; (2) possible lack of access to income on the underlying security during this period; and (3) expenses of enforcing its rights. While repurchase agreements involve certain risks not associated with direct investments in debt securities, the Fund follows procedures approved by the Fund’s Board of Directors that are designed to minimize such risks. These procedures include effecting repurchase transactions only with large, well-capitalized and well-established financial institutions whose financial condition will be continually monitored by Western Asset. In addition, as described above, the value of the collateral underlying the repurchase agreement will be at least equal to the repurchase price, including any accrued interest earned on the repurchase agreement. In the event of a default or bankruptcy by a selling financial institution, the Fund generally will seek to liquidate such collateral. However, the exercise of the Fund’s right to liquidate such collateral could involve certain costs or delays and, to the extent that proceeds from any sale upon a default of the obligation to repurchase were less than the repurchase price, the Fund could suffer a loss.

Variable Debt Risk

The absence of an active secondary market with respect to particular variable and floating rate instruments could make it difficult for the Fund to dispose of a variable or floating rate note if the issuer defaulted on its payment obligation or during periods that the Fund is not entitled to exercise its demand rights, and the Fund could, for these or other reasons, suffer a loss with respect to such instruments.

Credit Default Swap Risk

The Fund may invest in credit default swap transactions for hedging or investment purposes. Credit default swap agreements involve greater risks than if the Fund had invested in the reference obligation directly since, in addition to general market risks, credit default swaps are subject to illiquidity risk, counterparty risk and credit risk. The “buyer” in a credit default contract is obligated to pay the “seller” a periodic stream of payments over the term of the contract, provided that no event of default on an underlying reference obligation has occurred. If an event of default occurs, the seller must pay the buyer the full notional value, or “par value,” of the reference obligation through either physical settlement or cash settlement. The Fund may be either the buyer or seller in a credit default swap transaction. If the Fund is a buyer and no event of default occurs, the Fund will have made a series of periodic

60

payments and recover nothing of monetary value. However, if an event of default occurs, the Fund (if the buyer) will receive the full notional value of the reference obligation either through a cash payment in exchange for the asset or a cash payment in addition to owning the reference assets. As a seller, the Fund receives a fixed rate of income throughout the term of the contract, which typically is between six months and five years, provided that there is no event of default. The Fund currently intends to segregate assets on the Fund’s records in the form of cash, cash equivalents or liquid securities in an amount equal to the notional value of the credit default swaps of which it is the seller. If such assets are not fully segregated by the Fund, the use of credit default swap transactions could then be considered leverage for purposes of the 1940 Act and the Fund’s limits on leverage. Credit default swap transactions involve greater risks than if the Fund had invested in the reference obligation directly.

Structured Notes and Related Instruments Risk

The Fund may invest in “structured” notes and other related instruments, which are privately negotiated debt obligations where the principal and/or interest is determined by reference to the performance of a benchmark asset, market or interest rate (an “embedded index”), such as selected securities, an index of securities or specified interest rates, or the differential performance of two assets or markets, such as indexes reflecting bonds. Structured instruments may be issued by corporations, including banks, as well as by governmental agencies. Structured instruments frequently are assembled in the form of medium-term notes, but a variety of forms are available and may be used in particular circumstances. The terms of such structured instruments normally provide that their principal and/or interest payments are to be adjusted upwards or downwards (but ordinarily not below zero) to reflect changes in the embedded index while the structured instruments are outstanding. As a result, the interest and/or principal payments that may be made on a structured product may vary widely, depending on a variety of factors, including the volatility of the embedded index and the effect of changes in the embedded index on principal and/or interest payments. The rate of return on structured notes may be determined by applying a multiplier to the performance or differential performance of the referenced index(es) or other asset(s). Application of a multiplier involves leverage that will serve to magnify the potential for gain and the risk of loss.

Insolvency Considerations with Respect to Issuers of Indebtedness

Various laws enacted for the protection of U.S. creditors may apply to MBS in which the Fund invests. If a court in a lawsuit brought by an unpaid creditor or representative of the creditors of an issuer of MBS, such as a trustee in bankruptcy, were to find that the issuer did not receive fair consideration or reasonably equivalent value for incurring the indebtedness, and after giving effect to such indebtedness, the issuer (i) was insolvent, (ii) was engaged in a business for which the remaining assets of such issuer constituted unreasonably small capital or (iii) intended to incur, or believed that it would incur, debts beyond its ability to pay such debts as they mature, such court could determine to invalidate, in whole or in part, such indebtedness as a fraudulent conveyance, to subordinate such indebtedness to existing or future creditors of such issuer, or to recover amounts previously paid by such issuer in satisfaction of such indebtedness. The measure of insolvency for purposes of the foregoing will vary. Generally, an issuer would be considered insolvent at a particular time if the sum of its debts were then greater than all of its property at a fair valuation, or if the present fair saleable value of its assets was then less than the amount that would be required to pay its probable liabilities on its existing debts as they became absolute and matured. There can be no assurance as to what standard a court would apply in order to determine whether the issuer was “insolvent” after giving effect to the incurrence of the indebtedness in which the Fund invested or that, regardless of the method of valuation, a court would not determine that the issuer was “insolvent” upon giving effect to such incurrence. In addition, in the event of the insolvency of an issuer of indebtedness in which the Fund invests, payments made on such indebtedness could be subject to avoidance as a “preference” if made within a certain period of time (which may be as long as one year) before insolvency. In general, if payments on indebtedness are avoidable, whether as fraudulent conveyances or preferences, such payments can be recaptured from the Fund.

Portfolio Valuation for Financial Accounting and Other Reporting Purposes

Valuations of the portfolio investments may involve uncertainties and judgment determinations. Third-party pricing information can vary considerably from one dealer or pricing service to another, and may at times not be available regarding certain of the investments of the Fund. A disruption in the secondary markets for the investments of the Fund may make it difficult to obtain accurate market quotations for purposes of valuing portfolio investments for financial accounting, borrowing and other reporting purposes. Further, because of the overall size

61

and concentrations in particular markets and maturities of positions that may be held by the Fund from time to time, the liquidation values of portfolio investments may differ significantly from the valuations of such portfolio investments derived from the valuation methods described herein.

Some of the Fund’s portfolio investments will be in the form of securities that are not publicly traded. The fair value of securities and other investments that are not publicly traded may not be readily determinable. The Fund will value these investments quarterly at fair value, as determined in accordance with Statement of Financial Accounting Standards, or SFAS, No. 157, “Fair Value Measurements,” which may include unobservable inputs. Because such valuations are subjective, the fair value of certain of the Fund’s assets may fluctuate over short periods of time and the Fund’s determinations of fair value may differ materially from the values that would have been used if a ready market for these securities existed. The value of the Fund’s Common Stock could be adversely affected if the Fund’s determinations regarding the fair value of these investments were materially higher than the values that it ultimately realizes upon their disposal.

Inverse Floating Rate Securities and Tender Option Bonds Risk

Subject to certain limitations, the Fund may invest in inverse floating rate securities. Typically, inverse floating rate securities represent beneficial interests in a special purpose trust (sometimes called a “tender option bond trust”) formed by a third party sponsor for the purpose of holding MBS purchased from the Fund or from another third party. An investment in an inverse floating rate security may involve greater risk than an investment in a fixed-rate bond. Because changes in the interest rate on the underlying security or index inversely affect the residual interest paid on the inverse floating rate security, the value of an inverse floating rate security is generally more volatile than that of a fixed-rate bond.

Inverse floating rate securities have interest rate adjustment formulas which generally reduce or, in the extreme, eliminate the interest paid to the Fund when short-term interest rates rise, and increase the interest paid to the Fund when short-term interest rates fall. Inverse floating rate securities have varying degrees of liquidity, and the market for these securities is relatively volatile. These securities tend to underperform the market for fixed-rate bonds in a rising interest rate environment, but tend to outperform the market for fixed-rate bonds when interest rates decline. Shifts in long-term interest rates may, however, alter this tendency.

During times of reduced market liquidity, such as at the present, the Fund may not be able to sell MBS readily at prices reflecting the values at which the securities are carried on the Fund’s books. Sales of large blocks of MBS by market participants, such as the Fund, that are seeking liquidity can further reduce MBS prices in an illiquid market. The Fund may seek to make sales of large blocks of MBS as part of its investment strategy or it may be required to raise cash to re-collateralize, unwind or “collapse” tender option bond trusts that issued inverse floating rate securities to the Fund or to make payments to such trusts to enable them to pay for tenders of the short-term securities they have issued if the remarketing agents for those MBS are unable to sell the short-term securities in the marketplace to other buyers. The Fund’s potential exposure to losses related to or on inverse floating rate securities may increase beyond the value of the Fund’s inverse floater investments as the Fund may potentially be liable to fulfill all amounts owed to holders of the floating rate certificates.

Although volatile, inverse floating rate securities typically offer the potential for yields exceeding the yields available on fixed-rate bonds with comparable credit quality, coupon, call provisions and maturity. These securities usually permit the investor to convert the floating rate to a fixed rate (normally adjusted downward), and this optional conversion feature may provide a partial hedge against rising rates if exercised at an opportune time.

Investment in inverse floating rate securities may amplify the effects of the Fund’s use of leverage. Any economic effect of leverage through the Fund’s purchase of inverse floating rate securities will create an opportunity for increased Common Stock net income and returns, but may also result in losses if the cost of leverage exceeds the value of the securities underlying the tender option bond trust or the return on the inverse floating rate securities purchased by the Fund.

62

Other Investment Companies Risk

The Fund may invest in the securities of other investment companies. Such securities may be leveraged. As a result, the Fund may be indirectly exposed to leverage through an investment in such securities. Utilization of leverage is a speculative investment technique and involves certain risks. An investment in securities of other investment companies that are leveraged may expose the Fund to higher volatility in the market value of such securities and the possibility that the Fund’s long-term returns on such securities (and, indirectly, the long-term returns of the Common Stock) will be diminished.

Risks Related to Fund Distributions

Limited liquidity in the MBS market may affect the market price of MBS securities, thereby adversely affecting the net asset values of the Fund and its ability to make dividend distributions.

Derivatives Risk

The Fund may invest in derivative instruments, such as options contracts, futures contracts, options on futures contracts, indexed securities, credit linked notes, credit default swaps and other swap agreements for investment, hedging and risk management purposes; provided that the Fund’s use of derivative instruments, as measured by the total notional amount of all such instruments, will not exceed 20% of its Managed Assets. With respect to this limitation, the Fund may net derivatives with opposite exposure to the same underlying instrument. Notwithstanding the foregoing, the Fund may invest without limitation in Treasury futures, Eurodollar futures, interest rate swaps, swaptions or similar instruments and combinations thereof. A derivative is a financial contract whose value depends on changes in the value of one or more underlying assets or reference rates. Derivatives are subject to a number of risks described elsewhere in this prospectus, such as liquidity risk, interest rate risk, credit risk and management risk. Derivatives are also subject to counterparty risk, which is the risk that the other party in the transaction will not fulfill its contractual obligation. Changes in the credit quality of the companies that serve as the Fund’s counterparties with respect to its derivative transactions will affect the value of those instruments. By using derivatives that expose the Fund to counterparties, the Fund assumes the risk that its counterparties could experience financial hardships that could call into question their continued ability to perform their obligations. In addition, in the event of the insolvency of a counterparty to a derivative transaction, the derivative transaction would typically be terminated at its fair market value. If the Fund is owed this fair market value in the termination of the derivative transaction and its claim is unsecured, the Fund will be treated as a general creditor of such counterparty, and will not have any claim with respect to the underlying security. As a result, concentrations of such derivatives in any one counterparty would subject the Fund to an additional degree of risk with respect to defaults by such counterparty. Derivatives also involve the risk of mispricing or improper valuation and the risk that changes in the value of a derivative may not correlate perfectly with an underlying asset, interest rate or index. Suitable derivative transactions may not be available in all circumstances and there can be no assurance that the Fund will engage in these transactions to reduce exposure to other risks when that would be beneficial. If the Fund invests in a derivative instrument, it could lose more than the principal amount invested.

Derivative instruments can be illiquid, may disproportionately increase losses, and may have a potentially large impact on Fund performance.

The SEC adopted a new rule on October 28, 2020 that mandates that a fund’s derivatives risk management program provide for specific items as required by the rule, including compliance with a VaR test. Compliance with these new requirements will be required after a transition period that ends on August 19, 2022. Following the compliance date, these requirements may limit the ability of the Fund to use derivatives and reverse repurchase agreements and similar financing transactions as part of its investment strategies. These requirements may increase the cost of the Fund’s investments in derivatives, which could adversely affect shareholders.

Short Sales Risk

To the extent the Fund makes use of short sales for investment and/or risk management purposes, the Fund may be subject to risks associated with selling short. Short sales are transactions in which the Fund sells securities or other instruments that the Fund does not own. Short sales expose the Fund to the risk that it will be required to cover its short position at a time when the securities have appreciated in value, thus resulting in a loss to the Fund. The Fund may engage in short sales where it does not own or have the right to acquire the security sold short at no additional cost. The Fund’s loss on a short sale theoretically could be unlimited in a case where the Fund is unable, for whatever reason, to close out its short position. In addition, the Fund’s short selling strategies may limit its ability to benefit from increases in the markets. If the Fund engages in short sales, it will segregate liquid assets, enter into offsetting transactions or own positions covering its obligations; however, such segregation and cover requirements will not limit or offset losses on related positions. Short selling also involves a form of financial leverage that may exaggerate any losses realized by the Fund. Also, there is the risk that the counterparty to a short sale may fail to honor its contractual terms, causing a loss to the Fund. The Fund will incur transaction costs with any short sales, which will be borne by shareholders. Finally, regulations imposed by the SEC or other regulatory bodies relating to short selling may restrict the Fund’s ability to engage in short selling.

63

The Fund’s obligation to replace a borrowed security is secured by collateral deposited with the broker-dealer, usually cash, U.S. government securities or other liquid securities similar to those borrowed. The Fund is also required to segregate similar collateral to the extent, if any, necessary so that the value of both collateral amounts in the aggregate is at all times equal to at least 100% of the current market value of the security sold short. Depending on arrangements made with the broker-dealer from which the Fund borrowed the security regarding payment over of any payments received by us on such security, the Fund may not receive any payments (including interest) on the collateral deposited with such broker-dealer.

Risks of Short Economic Exposure Through Derivatives

The use by the Fund of derivatives such as options, forwards or futures contracts for investment and/or risk management purposes may subject the Fund to risks associated with short economic exposure through such derivatives. Taking a short economic position through derivatives exposes the Fund to the risk that it will be obligated to make payments to its counterparty if the underlying asset appreciates in value, thus resulting in a loss to the Fund. The Fund’s loss on a short position using derivatives theoretically could be unlimited.

Risks of Futures and Options on Futures

The use by the Fund of futures contracts and options on futures contracts to hedge interest rate risks involves special considerations and risks, as described below.

Liquidity Risk

The Fund may invest in MBS, for which there is no readily available trading market or which are otherwise illiquid. Liquidity risk exists when particular investments are difficult to sell. Securities may become illiquid after purchase by the Fund, particularly during periods of market turmoil. When the Fund holds illiquid investments, the portfolio may be harder to value, especially in changing markets, and if the Fund is forced to sell these investments in order to segregate assets or for other cash needs, the Fund may suffer a loss. The prices of securities with limited liquidity may be more volatile than prices of more liquid securities. Limited liquidity can also affect the market price of securities, thereby adversely affecting the Fund’s net asset value and its ability to make dividend distributions.

64

When-Issued and Delayed-Delivery Transactions Risk

The Fund may purchase fixed income securities on a when-issued basis, and may purchase or sell those securities for delayed delivery. When-issued and delayed-delivery transactions occur when securities are purchased or sold by the Fund with payment and delivery taking place in the future to secure an advantageous yield or price. Securities purchased on a when-issued or delayed-delivery basis may expose the Fund to counterparty risk of default as well as the risk that securities may experience fluctuations in value prior to their actual delivery. The Fund will not accrue income with respect to a when-issued or delayed-delivery security prior to its stated delivery date. Purchasing securities on a when-issued or delayed-delivery basis can involve the additional risk that the price or yield available in the market when the delivery takes place may not be as favorable as that obtained in the transaction itself.

Non-Diversification Risk

The Fund is classified as “non-diversified” under the 1940 Act. As a result, it can invest a greater portion of its assets in obligations of a single issuer than a “diversified” fund. The Fund may therefore be more susceptible than a diversified fund to being adversely affected by any single corporate, economic, political or regulatory occurrence. See “The Fund’s Investments.” The Fund intends to qualify for the special tax treatment available to “regulated investment companies” under Subchapter M of the Code, and thus intends to satisfy the diversification requirements of Subchapter M, including the less stringent diversification requirement that applies to the percent of its total assets that are represented by cash and cash items (including receivables), U.S. government securities, the securities of other regulated investment companies and certain other securities.

Risks Related to Potential Conflicts of Interest

LMPFA, Western Asset and the portfolio managers have interests which may conflict with the interests of the Fund. LMPFA and Western Asset may at some time in the future manage and/or advise other investment funds or accounts with the same or substantially similar investment objective and strategies as the Fund. As a result, LMPFA, Western Asset and the Fund’s portfolio managers may devote unequal time and attention to the management of the Fund and those other funds and accounts, and may not be able to formulate as complete a strategy or identify equally attractive investment opportunities as might be the case if they were to devote substantially more attention to the management of the Fund. LMPFA, Western Asset and the Fund’s portfolio managers may identify a limited investment opportunity that may be suitable for multiple funds and accounts, and the opportunity may be allocated among these several funds and accounts, which may limit the Fund’s ability to take full advantage of the investment opportunity. Additionally, transaction orders may be aggregated for multiple accounts for purpose of execution, which may cause the price or brokerage costs to be less favorable to the Fund than if similar transactions were not being executed concurrently for other accounts. At times, a portfolio manager may determine that an investment opportunity may be appropriate for only some of the funds and accounts for which he or she exercises investment responsibility, or may decide that certain of the funds and accounts should take differing positions with respect to a particular security. In these cases, the portfolio manager may place separate transactions for one or more funds or accounts which may affect the market price of the security or the execution of the transaction, or both, to the detriment or benefit of one or more other funds and accounts. For example, a portfolio manager may determine that it would be in the interest of another account to sell a security that the Fund holds, potentially resulting in a decrease in the market value of the security held by the Fund.

The portfolio managers may also engage in cross trades between funds and accounts, may select brokers or dealers to execute securities transactions based in part on brokerage and research services provided to LMPFA or Western Asset which may not benefit all funds and accounts equally and may receive different amounts of financial or other benefits for managing different funds and accounts. Finally, LMPFA or its affiliates may provide more services to some types of funds and accounts than others.

There is no guarantee that the policies and procedures adopted by LMPFA, Western Asset and the Fund will be able to identify or mitigate the conflicts of interest that arise between the Fund and any other investment funds or accounts that LMPFA and/or Western Asset may manage or advise from time to time.

65

Counterparty Risk

The Fund will be subject to credit risk with respect to the counterparties to the derivative contracts (whether a clearing corporation in the case of exchange-traded instruments or another party in the case of over-the-counter instruments) and other instruments entered into directly by the Fund or held by special purpose or structured vehicles in which the Fund invests. If a counterparty becomes bankrupt or otherwise fails to perform its obligations under a derivative contract due to financial difficulties or otherwise, the Fund may experience significant delays in obtaining any recovery under the derivative contract in a dissolution, assignment for the benefit of creditors, liquidation, winding-up, bankruptcy, or other analogous proceeding. In addition, in the event of the insolvency of a counterparty to a derivative transaction, the derivative transaction would typically be terminated at its fair market value. If the Fund is owed this fair market value in the termination of the derivative transaction and its claim is unsecured, the Fund will be treated as a general creditor of such counterparty, and will not have any claim with respect to the underlying reference asset or security. The Fund may obtain only a limited recovery or may obtain no recovery in such circumstances.

Counterparty risk with respect to certain exchange-traded and over-the-counter derivatives may be further complicated by U.S. financial reform legislation.

Portfolio Turnover Risk

The Fund’s annual portfolio turnover rate was 11% in 2020 and may vary greatly from year to year. Changes to the investments of the Fund may be made regardless of the length of time particular investments have been held. A high portfolio turnover rate may result in increased transaction costs for the Fund in the form of increased dealer spreads and other transactional costs, which may have an adverse impact on the Fund’s performance. In addition, high portfolio turnover may result in the realization of net short-term capital gains by the Fund which, when distributed to stockholders, will be taxable as ordinary income. A high portfolio turnover may increase the Fund’s current and accumulated earnings and profits, resulting in a greater portion of the Fund’s distributions being treated as a dividend to the Fund’s stockholders. The portfolio turnover rate of the Fund will vary from year to year, as well as within a given year.

Temporary Defensive Strategies Risk

When Western Asset anticipates unusual market or other conditions, the Fund may temporarily depart from its principal investment strategies as a defensive measure and invest all or a portion of its assets non-U.S. government securities which have received the highest investment grade credit rating and U.S. government securities, including bills, notes and bonds differing as to maturity and rates of interest that are either issued or guaranteed by the Treasury or by U.S. government agencies or instrumentalities; certificates of deposit issued against funds deposited in a bank or a savings and loan association; commercial paper; bankers’ acceptances; bank time deposits; shares of money market funds; repurchase agreements with respect to any of the foregoing; or any other fixed income securities that Western Asset considers consistent with this strategy. To the extent that the Fund invests defensively, it may not achieve its investment objectives.

Anti-Takeover Provisions Risk.

The Fund’s Charter and Bylaws include provisions that are designed to limit the ability of other entities or persons to acquire control of the Fund for short-term objectives, including by converting the Fund to open-end status or changing the composition of the Board, that may be detrimental to the Fund’s ability to achieve its primary investment objective of seeking current income. The Fund’s Bylaws also contain a provision providing that the Board of Directors has adopted a resolution to opt in the Fund to the provisions of the MCSAA. Such provisions may limit the ability of shareholders to sell their shares at a premium over prevailing market prices by discouraging a third party from seeking to obtain control of the Fund. There can be no assurance, however, that such provisions will be sufficient to deter activist investors that seek to cause the Fund to take actions that may not be aligned with the interests of long-term shareholders. See “Certain Provisions in the Charter and Bylaws” and “Certain Provisions in the Charter and Bylaws—Maryland Control Share Acquisition Act.”

Market Events Risk

The market values of securities or other assets will fluctuate, sometimes sharply and unpredictably, due to changes in general market conditions, overall economic trends or events, governmental actions or intervention, actions taken by the U.S. Federal Reserve or foreign central banks, market disruptions caused by trade disputes or other factors, political developments, investor sentiment, the global and domestic effects of a pandemic, and other factors that may or may not be related to the issuer of the security or other asset. Economies and financial markets throughout the world are increasingly interconnected. Economic, financial or political events, trading and tariff arrangements, public health events, terrorism, natural disasters and other circumstances in one country or region could have profound impacts on global economies or markets. As a result, whether or not the Fund invests in securities of issuers located in or with significant exposure to the countries directly affected, the value and liquidity of the Fund’s investments may be negatively affected. These market events also could have an acute effect on individual issuers or related groups of issuers. These risks also could adversely affect individual issuers and securities markets, interest rates, secondary trading, ratings, credit risk, inflation, deflation and other factors relating to the Fund’s investments and the market value and net asset value of the Common Stock.

More recently, the rapid and global spread of a highly contagious respiratory disease, Coronavirus/COVID-19, has resulted in restrictions on international and, in some cases, local travel, temporary shuttering of various businesses, strained healthcare systems, disruptions to supply chains, consumer demand and employee availability, and widespread panic and uncertainty regarding the duration and long-term effects of this pandemic. In addition, a pandemic or widespread public health event may result in a sustained economic downturn or a global recession, domestic and foreign political and social instability, damage to diplomatic and international trade relations and increased volatility and/or decreased liquidity in the securities markets. Economies and financial markets throughout the world are increasingly interconnected. As a result, whether or not the Fund invests in securities of issuers located in or with significant exposure to the countries directly affected, the value and liquidity of the Fund’s investments may be negatively affected. Certain risks, such as interest rate risk, credit risk, liquidity risk and counterparty risk, may be heightened as a result of such market events. The U.S. government and the Federal Reserve, as well as certain foreign governments and central banks, are taking steps to support financial markets, including by keeping interest rates at historically low levels. This and other government intervention may not work as intended, particularly if the efforts are perceived by investors as being unlikely to achieve the desired results. Specifically, increased unemployment due to these market events (including Coronavirus/COVID-19 and future pandemics) and potentially insufficient government responses to such events may cause the MBS and mortgage whole loans in which the Fund invests to decrease in value due to borrowers suspending or ceasing payments on their mortgages.

The Fund’s commercial mortgages collateralized by hotels and retail properties are disproportionately impacted by the effects of COVID-19. The Fund expects over the near- and long-term that the economic impacts of the pandemic will impact the financial stability of these borrowers. As a result, some of these borrowers may have experienced financial hardship, which would make it difficult to meet their payment obligations, leading to requests for forbearance and elevated levels of delinquency and default, which would have an adverse effect on the Fund, the value of these assets and the Fund’s results of operations and financial condition.

The Fund is subject to risks related to residential mortgages. Over the near- and long-term, the economic and market disruptions caused by the COVID-19 pandemic are likely to adversely impact the financial condition of certain borrowers underlying the Fund’s residential mortgage loan investments. As a result, the Fund anticipates that the number of borrowers who become delinquent or default on their loans may increase significantly. Such increased levels of payment delinquencies, defaults, foreclosures, or losses would adversely affect the Fund’s business, the value of these assets, results of operations and financial position. Future outbreaks involving other highly infectious or contagious diseases could have similar adverse effects.

Managed Distribution Risk

Under a managed distribution policy, the Fund would intend to make monthly distributions to stockholders at a fixed rate per share of Common Stock or a fixed percentage of net asset value that may include periodic distributions of long-term capital gains. Under a managed distribution policy, if, for any monthly distribution, ordinary income (that is, net investment income and any net short-term capital gain) and net realized capital gains were less than the amount of the distribution, the difference would be distributed from the Fund’s previously accumulated earnings and profits or cash generated from the sale of Fund assets. If, for any fiscal year, the total distributions exceeded ordinary income and net realized capital gains (the “Excess”), the Excess would decrease the Fund’s total assets and, as a result, would have the likely effect of increasing the Fund’s expense ratio. There is a risk that the Fund would not eventually realize capital gains in an amount corresponding to a distribution of the Excess. In addition, in order to make such distributions, the Fund may have to sell a portion of its investment portfolio at a time when independent investment judgment might not dictate such action. If the Fund were to issue senior securities and not be in compliance with the asset coverage requirements of the 1940 Act, the Fund would be required to suspend the managed distribution policy. Pursuant to the requirements of the 1940 Act and other applicable laws, a notice will accompany each monthly distribution disclosing the sources of the distribution.

Personnel Turnover Risk

As a result of current deteriorating market conditions or other reasons, LMPFA and Western Asset may need to implement cost reductions in the future which could make the retention of qualified and experienced personnel more difficult and could lead to personnel turnover. Loss of significant personnel, whether in terms of number or role in managing the Fund or an inability to hire qualified replacements in a timely manner, could adversely affect the operation of the Fund and its ability to achieve its investment objectives and pursue its anticipated strategies.
