generally will be available if our failure to meet the gross income tests was due to reasonable cause and not due to willful neglect and we file a schedule of the sources of our gross income in accordance with Treasury regulations. It is not possible to state whether we would be entitled to the benefit of these relief provisions in all circumstances. If these relief provisions are inapplicable to a particular set of circumstances, we will not qualify as a REIT. As discussed above under —Taxation of REITs in General, even where these relief provisions apply, the Code imposes a tax based upon the amount by which we fail to satisfy the particular gross income test.
Asset Tests
At the close of each calendar quarter, we must also satisfy five tests relating to the nature of our assets. First, at least 75% of the value of our total assets must be represented by some combination of real estate assets, cash, cash items, U.S. government securities, and, under some circumstances, stock or debt instruments purchased with new capital. For this purpose, real estate assets include interests in real property, such as land, buildings, and leasehold interests in real property (and certain ancillary personal property), stock of other corporations that qualify as REITs, some kinds of MBS and mortgage loans, and debt instruments (whether or not secured by real property) that are issued by a publicly offered REIT (i.e., a REIT that is required to file annual and periodic reports with the Securities and Exchange Commission under the Securities Exchange Act of 1934). Assets that do not qualify for purposes of the 75% asset test are subject to the additional asset tests described below.
Second, the value of any one issuers securities that we own may not exceed 5% of the value of our total assets.
Third, we may not own more than 10% of any one issuers outstanding securities, as measured by either voting power or value. The 5% and 10% asset tests do not apply to real estate assets, securities of TRSs, and qualified REIT subsidiaries and the value prong of the 10% asset test does not apply to straight debt having specified characteristics and to certain other securities described below. Solely for purposes of the 10% asset test, the determination of our interest in the assets of a partnership or limited liability company in which we own an interest will be based on our proportionate interest in any securities issued by the partnership or limited liability company, excluding for this purpose certain securities described in the Code.
Fourth, the aggregate value of all securities of TRSs that we hold may not exceed 25% (or, for our 2018 and subsequent taxable years, 20%) of the value of our total assets.
Fifth, no more than 25% of the total value of our assets may be represented by nonqualified publicly offered REIT debt instruments (i.e., real estate assets that would cease to be real estate assets if debt instruments issued by publicly offered REITs were not included in the definition of real estate assets).
Notwithstanding the general rule, as noted above, that for purposes of the REIT income and asset tests, we are treated as owning our proportionate share of the underlying assets of a subsidiary partnership, if we hold indebtedness issued by a partnership, the indebtedness will be subject to, and may cause a violation of, the asset tests unless the indebtedness is a qualifying mortgage asset, or other conditions are met. Similarly, although stock of another REIT is a qualifying asset for purposes of the REIT asset tests, any non-mortgage debt that is issued by a non-publicly offered REIT may not so qualify (such debt, however, will not be treated as a security for purposes of the 10% value test, as explained below).
The Code provides that certain securities will not cause a violation of the 10% value test described above. Such securities include instruments that constitute straight debt, which includes, among other things, securities having certain contingency features. A security does not qualify as straight debt where a REIT (or a controlled TRS of the REIT) owns other securities of the same issuer which do not qualify as straight debt, unless the value of those other securities constitute, in the aggregate, 1% or less of the total value of that issuers outstanding securities. In addition to straight debt, the Code provides that certain other securities will not violate the 10% value test. Such securities include (a) any loan made to an individual or an estate, (b) certain rental agreements pursuant to which one or more payments are to be made in subsequent years (other than agreements between a REIT and certain persons related to the REIT under attribution rules), (c) any obligation to pay rents from real property, (d) securities issued by governmental entities that are not dependent in whole or in part on the profits of (or payments made by) a non-governmental entity, (e) any security (including debt securities) issued by another REIT, and (f) any debt instrument issued by a partnership if the partnerships income is of a nature that it would satisfy the 75% gross income test described above under —Income Tests. The Code also provides that in applying the 10% value test, a debt security issued by a partnership is not taken into account to the extent, if any, of the REITs proportionate interest in that partnership.
