Item 8.01 Other Events

Tax Matters Update

This discussion is a supplement to, and is intended to be read together with, the discussion under the heading “Material United States Federal Income Tax Considerations” included in Excel Trust, Inc.’s and Excel Trust, L.P.’s Registration Statement on Form S-3 (File Nos. 333-189517 and 333-189517-01) and in Excel Trust, Inc.’s Registration Statements on Form S-3 (File Nos. 333-174022, 333-174023 and 333-181399), which we refer to as the Registration Statements. This summary is for general information only and is not tax advice.

The following discussion supersedes, in its entirety, the discussions under the headings “— Taxation of Non-U.S. Holders — Foreign Accounts” and “Foreign Accounts” in the Registration Statements, and any other similar discussion of foreign accounts in the Registration Statements, in the discussion under Item 8.01 included in our Current Report on Form 8-K filed with the Securities and Exchange Commission (the “SEC”) on November 9, 2012 and in the discussion under Item 8.01 included in our Current Report on Form 8-K filed with the SEC on March 1, 2013.

Withholding taxes may apply to certain types of payments made to “foreign financial institutions” (as specially defined in the Code) and certain other non-U.S. entities. Specifically, a 30% withholding tax may be imposed on dividends and interest on, and gross proceeds from the sale or other disposition of, our capital stock or debt securities paid to a foreign financial institution or to a non-financial foreign entity, unless (1) the foreign financial institution undertakes certain investigation and reporting, (2) the non-financial foreign entity either certifies it does not have any substantial United States owners or furnishes identifying information regarding each substantial United States owner, or (3) the foreign financial institution or non-financial foreign entity otherwise qualifies for an exemption from these rules. If the payee is a foreign financial institution and is subject to the diligence and reporting requirements in clause (1) above, it must enter into an agreement with the United States Treasury requiring, among other things, that it undertake to identify accounts held by certain United States persons or United States-owned foreign entities, annually report certain information about such accounts, and withhold 30% on payments to non-compliant foreign financial institutions and certain other account holders. Foreign financial institutions located in jurisdictions that have an intergovernmental agreement with the United States governing these rules may be subject to different rules.

The withholding provisions described above are currently scheduled to apply to payments of dividends or interest made on or after July 1, 2014 and to payments of gross proceeds from a sale or other disposition of capital stock or debt securities on or after January 1, 2017. Because we may not know the extent to which a distribution is a dividend for United States federal income tax purposes at the time it is made, for purposes of these withholding rules we may treat the entire distribution as a dividend. In addition, these rules currently would not apply to debt securities issued before July 1, 2014, provided that if any such debt securities are significantly modified (within the meaning of applicable Treasury Regulations) on or after July 1, 2014, payments on such debt securities could be subject to the withholding rules described above. Prospective investors should consult their tax advisors regarding these withholding provisions.
