Market Measure Business Day

A “Market Measure Business Day” means a day on which:

The Basket

The Basket is designed to allow investors to participate in the percentage changes in the levels of the Basket Components from the Starting Value to the Ending Value of the Basket. The Basket Components are described in the section entitled “The Basket Components” below. Each Basket Component was assigned an initial weight on the pricing date, as set forth in the table below.

For more information on the calculation of the value of the Basket, please see the section entitled “Description of LIRNs—Basket Market Measures” beginning on page PS-20 of product supplement EQUITY INDICES LIRN-1.

On the pricing date, for each Basket Component, the Initial Component Weight, the closing level, the Component Ratio and the initial contribution to the Basket value were as follows:

On each calculation day during the Maturity Valuation Period, the calculation agent will calculate the value of the Basket on such day by summing the products of (a) the closing level for each Basket Component on such day and (b) the Component Ratio applicable to such Basket Component. The Ending Value of the Basket will be the average value of the Basket on each calculation day during the Maturity Valuation Period. If a Market Disruption Event occurs as to any Basket Component on any scheduled calculation day, the closing level of that Basket Component will be determined as more fully described in the section entitled “Description of LIRNs—The Starting Value and the Ending Value—Ending Value” beginning on page PS-17 of product supplement EQUITY INDICES LIRN-1.

While actual historical information on the Basket did not exist before the pricing date, the following graph sets forth the hypothetical historical performance of the Basket from January 1, 2008 through January 26, 2017. The graph is based upon actual daily historical levels of the Basket Components, hypothetical Component Ratios based on the closing levels of the Basket Components as of December 31, 2007, and a Basket value of 100.00 as of that date. This hypothetical historical data on the Basket is not necessarily indicative of the future performance of the Basket or what the value of the notes may be. Any hypothetical historical upward or downward trend in the value of the Basket during any period set forth below is not an indication that the value of the Basket is more or less likely to increase or decrease at any time over the term of the notes.

The S&P 500 ^® Index (“SPX”)

The S&P 500 ^® Index (Bloomberg ticker: “SPX”) is published by S&P Dow Jones Indices LLC, the index sponsor. The SPX is intended to provide an indication of the pattern of common stock price movement. The calculation of the level of the SPX is based on the relative value of the aggregate market value of the common stocks of 500 companies as of a particular time compared to the aggregate average market value of the common stocks of 500 similar companies during the base period of the years 1941 through 1943.

S&P chooses companies for inclusion in the SPX with the aim of achieving a distribution by broad industry groupings that approximates the distribution of these groupings in the common stock population of its Stock Guide Database of over 10,000 companies, which S&P uses as an assumed model for the composition of the total market. Relevant criteria employed by S&P include the viability of the particular company, the extent to which that company represents the industry group to which it is assigned, the extent to which the market price of that company’s common stock generally is responsive to changes in the affairs of the respective industry and the market value and trading activity of the common stock of that company. Eleven main groups of companies constitute the SPX, with the approximate percentage of the market capitalization of the SPX included in each group as of December 30, 2016 indicated in parentheses: Consumer Discretionary (12.0%); Consumer Staples (9.4%); Energy (7.6%); Financials (14.8%); Health Care (13.6%); Industrials (10.3%); Information Technology (20.8%); Materials (2.8%); Real Estate (2.9%); Telecommunication Services (2.7%); and Utilities (3.2%). S&P may from time to time, in its sole discretion, add companies to, or delete companies from, the SPX to achieve the objectives stated above.

S&P calculates the SPX by reference to the prices of the constituent stocks of the SPX without taking account of the value of dividends paid on those stocks. As a result, the return on the notes will not reflect the return you would realize if you actually owned the SPX constituent stocks and received the dividends paid on those stocks.

Computation of the Index

Historically, the market value of any component stock of the SPX was calculated as the product of the market price per share and the number of then outstanding shares of such component stock. In March 2005, S&P began shifting the SPX halfway from a market capitalization weighted formula to a float-adjusted formula, before moving the SPX to full float adjustment on September 16, 2005. S&P’s criteria for selecting stocks for the SPX did not change with the shift to float adjustment. However, the adjustment affects each company’s weight in the SPX.

Under float adjustment, the share counts used in calculating the SPX reflect only those shares that are available to investors, not all of a company’s outstanding shares. Float adjustment excludes shares that are closely held by control groups, other publicly traded companies or government agencies.

In September 2012, all shareholdings representing more than 5% of a stock’s outstanding shares, other than holdings by “block owners,” were removed from the float for purposes of calculating the SPX. Generally, these “control holders” will include officers and directors, private equity, venture capital and special equity firms, other publicly traded companies that hold shares for control, strategic partners, holders of restricted shares, employee stock ownership plans, employee and family trusts, foundations associated with the company, holders of unlisted share classes of stock, government entities at all levels (other than government retirement/pension funds) and any individual person who controls a 5% or greater stake in a company as reported in regulatory filings. However, holdings by block owners, such as depositary banks, pension funds, mutual funds and ETF providers, 401(k) plans of the company, government retirement/pension funds, investment funds of insurance companies, asset managers and investment funds, independent foundations and savings and investment plans, will ordinarily be considered part of the float.

Treasury stock, stock options, restricted shares, equity participation units, warrants, preferred stock, convertible stock, and rights are not part of the float. Shares held in a trust to allow investors in countries outside the country of domicile, such as depositary shares and Canadian exchangeable shares are normally part of the float unless those shares form a control block. If a company has multiple classes of stock outstanding, shares in an unlisted or non-traded class are treated as a control block.

For each stock, an investable weight factor (“IWF”) is calculated by dividing the available float shares, by the total shares outstanding. As of September 21, 2012, available float shares are defined as the total shares outstanding less shares held by control holders. This calculation is subject to a 5% minimum threshold for control blocks. For example, if a company’s officers and directors hold 3% of the company’s shares, and no other control group holds 5% of the company’s shares, S&P would assign that company an IWF of 1.00, as no control group meets the 5% threshold. However, if a company’s officers and directors hold 3% of the company’s shares and another control group holds 20% of the company’s shares, S&P would assign an IWF of 0.77, reflecting the fact that 23% of the company’s outstanding shares are considered to be held for control. For companies with multiple classes of stock, S&P calculates the weighted average IWF for each stock using the proportion of the total company market capitalization of each share class as weights.

The SPX is calculated using a base-weighted aggregate methodology. The level of the SPX reflects the total market value of all component stocks relative to the base period of the years 1941 through 1943. An indexed number is used to represent the results of this calculation in order to make the level easier to work with and track over time. The actual total market value of the component stocks during the base period of the years 1941 through 1943 has been set to an indexed level of 10. This is often indicated by the notation 1941- 43 = 10. In practice, the daily calculation of the SPX is computed by dividing the total market value of the component stocks by the “index divisor.” By itself, the index divisor is an arbitrary number. However, in the context of the calculation of the SPX, it serves as a link to the original base period level of the SPX. The index divisor keeps the SPX comparable over time and is the manipulation point for all adjustments to the SPX, which is index maintenance.

Index Maintenance

Index maintenance includes monitoring and completing the adjustments for company additions and deletions, share changes, stock splits, stock dividends and stock price adjustments due to company restructuring or spinoffs. Some corporate actions, such as stock splits and stock dividends require changes in the common shares outstanding and the stock prices of the companies in the SPX, and do not require index divisor adjustments.

To prevent the level of the SPX from changing due to corporate actions, corporate actions which affect the total market value of the SPX require an index divisor adjustment. By adjusting the index divisor for the change in market value, the level of the SPX remains constant and does not reflect the corporate actions of individual companies in the SPX. Index divisor adjustments are made after the close of trading and after the calculation of the SPX closing level.

Changes in a company’s shares outstanding of 5.00% or more due to public offerings are made as soon as reasonably possible. All other changes of 5.00% or more (due to, for example, tender offers, Dutch auctions, voluntary exchange offers, company stock repurchases, private placements, acquisitions of private companies or non-index companies that do not trade on a major exchange, redemptions, exercise of options, warrants, conversion of preferred stock, notes, debt, equity participations, at-the-market stock offerings or other recapitalizations) are made weekly, and are announced on Fridays for implementation after the close of trading on the following Friday. Changes of less than 5.00% due to a company’s acquisition of another company in the SPX are made as soon as reasonably possible. All other changes of less than 5.00% are accumulated and made quarterly on the third Friday of March, June, September, and December, and are usually announced two to five days prior.

Changes in IWFs of more than five percentage points caused by corporate actions (such as merger and acquisition activity, restructurings, or spinoffs) will be made as soon as reasonably possible. Other changes in IWFs will be made annually when IWFs are reviewed.

The MSCI EAFE ^® Index (“MXEA”) and the MSCI Emerging Markets Index (“MXEF”)

MSCI Inc. (“MSCI”) is the index sponsor of the MSCI EAFE ^® Index (Bloomberg symbol: “MXEA”) and the MSCI Emerging Markets Index (Bloomberg symbol: “MXEF”). All disclosures in this term sheet regarding the MXEA and the MXEF have been derived from publicly available sources, which we have not independently verified. The information summarizes the current index methodology as published by MSCI and may be changed by MSCI at any time. Additional information on the Index is available at the following website: http://www.msci.com. No information on that website is deemed to be included or incorporated by reference in this term sheet.

General – MSCI Indices

The MSCI indices were founded in 1969 by Capital International as the first international performance benchmarks constructed to facilitate accurate comparison of world markets. Morgan Stanley acquired the rights to license the MSCI indices in 1986. In November 1998, Morgan Stanley transferred all rights to the MSCI indices to MSCI, a Delaware corporation formed and operated jointly by Morgan Stanley and Capital International. In 2004, MSCI acquired Barra, Inc., a provider of risk analytics, and firm-wide investment risk management systems and services and merged this with MSCI. In 2007, MSCI completed an initial public offering and was listed on the New York Stock Exchange, with Morgan Stanley retaining a controlling interest. In 2009, MSCI and Morgan Stanley fully separated. The MSCI single country standard equity indices have covered the world’s developed markets since 1969, and in 1988, MSCI commenced coverage of the emerging markets.

MSCI provides global equity indices intended to measure equity performance in international markets and the MSCI indices are designed to serve as global equity performance benchmarks. In constructing these indices, MSCI applies its index construction and maintenance methodology across developed, emerging and frontier markets.

MSCI enhanced the methodology used in its international equity indices. The MSCI Standard and MSCI Small Cap Indices, along with the other MSCI equity indices based on them, transitioned to the Global Investable Market Indexes methodology described below. The transition was completed at the end of May 2008. The enhanced MSCI Standard Indices are composed of the MSCI Large Cap and Mid Cap Indices. The MSCI Global Small Cap Index transitioned to the MSCI Small Cap Index resulting from the Global Investable Market Indices methodology and contains no overlap with constituents of the transitioned MSCI Standard Indices. Together, the relevant MSCI Large Cap, Mid Cap, and Small Cap Indices will make up the MSCI investable market index for each country, composite, sector, and style index that MSCI offers.

Index Construction

MSCI undertakes an index construction process for the MSCI Global Investable Market Indexes, which involves:

Defining the Equity Universe. The equity universe is defined by:

Determining the Market Investable Equity Universes. A market investable equity universe for a market is derived by identifying eligible listings for each security in the equity universe and applying investability screens to individual companies and securities in the equity universe that are classified in that market. A market is equivalent to a single country, except in DM Europe, where all DM countries in Europe are aggregated into a single market for index construction purposes. Subsequently, individual DM Europe country indices within the MSCI Europe Index are derived from the constituents of the MSCI Europe Index under the Global Investable Market Indexes methodology.

In identifying eligible listings, a security may have a listing in the country where it is classified (i.e. “local listing”) and/or in a different country (i.e. “foreign listing”). Securities may be represented by either a local listing or a foreign listing (including a depositary receipt) in the equity universe. A security may be represented by a foreign listing only if the following conditions are met:

The investability screens used to determine the investable equity universe in each market are as follows:

Defining Market Capitalization Size Segments for Each Market. Once a market investable equity universe is defined, it is segmented into the following size–based indices:

Creating the size segment indices in each market involves the following steps:

Index Continuity Rules for the Standard Indices. In order to achieve index continuity, as well as to provide some basic level of diversification within a market index, and notwithstanding the effect of other index construction rules described in this section, a minimum number of five constituents will be maintained for a DM Standard Index and a minimum number of three constituents will be maintained for an EM Standard Index.

Creating Style Indices within Each Size Segment. All securities in the investable equity universe are classified into value or growth segments using the MSCI Global Value and Growth methodology.

Classifying Securities under the Global Industry Classification Standard . All securities in the global investable equity universe are assigned to the industry that best describes their business activities. To this end, MSCI has designed, in conjunction with Standard & Poor’s, the GICS. Under the GICS, each company is assigned to one sub-industry according to its principal business activity. Therefore, a company can belong to only one industry grouping at each of the four levels of the GICS.

Index Maintenance

The MSCI Global Investable Market Indexes are maintained with the objective of reflecting the evolution of the underlying equity markets and segments on a timely basis, while seeking to achieve index continuity, continuous investability of constituents and replicability of the indices, index stability and low index turnover. In particular, index maintenance involves:

(i)  Semi–Annual Index Reviews (“SAIRs”) in May and November of the Size Segment and Global Value and Growth Indices which include:

(ii)  Quarterly Index Reviews (“QIRs”) in February and August of the Size Segment Indices aimed at:

(iii)  Ongoing Event-Related Changes: changes of this type are generally implemented in the indices as they occur. Significantly large IPOs are included in the indices after the close of the company’s tenth day of trading.

Calculation of the Index

The MSCI equity indices are free float-adjusted market capitalization indices that are designed to measure the market performance, including price performance, of the equity securities in an index. The MSCI equity indices are calculated using the Laspeyres’ concept of a weighted arithmetic average together with the concept of chain-linking. Each index component is included at a weight that reflects the ratio of its free float-adjusted market capitalization (i.e., free public float multiplied by price) to the free float-adjusted market capitalization of all the components included in the index. MSCI defines the free float of a security as the proportion of shares outstanding that is deemed to be available for purchase in the public equity markets by international investors.

Each MSCI Global Investable Market Index is calculated in the relevant local currency as well as in U.S. dollars, with price, gross and net returns.

Neither we nor any of our affiliates, or MLPF&S, accepts any responsibility for the calculation, maintenance, or publication of, or for any error, omission, or disruption in, the MSCI indices. MSCI does not guarantee the accuracy or the completeness of the MSCI indices or any data included in the MSCI indices. MSCI assumes no liability for any errors, omissions, or disruption in the calculation and dissemination of the MSCI indices. MSCI disclaims all responsibility for any errors or omissions in the calculation and dissemination of the MSCI indices or the manner in which the MSCI indices are applied in determining the amount payable on the notes at maturity.
