SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Business and Organization

American Assets Trust, Inc. (which may be referred to in these financial statements as the “Company,” “we,” “us,” or “our”) is a Maryland corporation formed on July 16, 2010 that did not have any operating activity until the consummation of our initial public offering on January 19, 2011. The Company is the sole general partner of American Assets Trust, L.P., a Maryland limited partnership formed on July 16, 2010 (the “Operating Partnership”).

Basis of Presentation

Our consolidated financial statements include the accounts of the Company, our Operating Partnership and our subsidiaries. The equity interests of other investors in our Operating Partnership are reflected as noncontrolling interests.

All significant intercompany transactions and balances are eliminated in consolidation.

The accompanying consolidated financial statements of the Company and the Operating Partnership have been prepared in accordance with the rules applicable to Form 10-Q and include all information and footnotes required for interim financial statement presentation, but do not include all disclosures required under accounting principles generally accepted in the United States (“GAAP”) for annual financial statements. In the opinion of management, all adjustments (consisting of normal recurring adjustments, except as otherwise noted) considered necessary for a fair presentation have been included. These financial statements should be read in conjunction with the audited consolidated financial statements and notes therein included in the Company's and Operating Partnership's annual report on Form 10-K for the year ended December 31, 2015.

The preparation of financial statements in conformity with GAAP requires us to make estimates and assumptions that in certain circumstances affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities, and revenues and expenses. These estimates are prepared using our best judgment, after considering past, current and expected events and economic conditions. Actual results could differ from these estimates.

Any reference to the number of properties, square footage, employee numbers or percentages of beneficial ownership of our shares are unaudited and outside the scope of our independent registered public accounting firm’s review of our financial statements in accordance with the standards of the United States Public Company Accounting Oversight Board.

Significant Accounting Policies

We describe our significant accounting policies in Note 1 to the consolidated financial statements in Item 8 of our Annual Report on Form 10-K for the year ended December 31, 2015. Except for the adoption of the consolidation and debt issuance costs standards discussed below, there have been no changes to our significant accounting policies during the nine months ended September 30, 2016.

Segment Information

Segment information is prepared on the same basis that our chief operating decision maker reviews information for operational decision-making purposes. We operate in four business segments: the acquisition, redevelopment, ownership and management of retail real estate, office real estate, multifamily real estate and mixed-use real estate. The products for our retail segment primarily include rental of retail space and other tenant services, including tenant reimbursements, parking and storage space rental. The products for our office segment primarily include rental of office space and other tenant services, including tenant reimbursements, parking and storage space rental. The products for our multifamily segment include rental of apartments and other tenant services. The products of our mixed-use segment include rental of retail space and other tenant services, including tenant reimbursements, parking and storage space rental and operation of a 369-room all-suite hotel.

Recent Accounting Pronouncements

In May 2014, the FASB issued Update No. 2014-09, Revenue from Contracts with Customers. Update No. 2014-09 establishes that companies may recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. This pronouncement is effective for annual reporting periods beginning after December 15, 2017, including interim reporting periods within that reporting period. We are in the process of evaluating the impact this pronouncement will have on our consolidated financial statements.

In February 2015, the FASB issued an ASU that requires reporting entities to evaluate whether they should consolidate certain legal entities. The ASU modifies the evaluation of whether limited partnerships and similar legal entities are voting interest entities ("VIEs") and eliminates the presumption that a general partner should consolidate a limited partnership. This affects the consolidation analysis of reporting entities that are involved with VIEs, particularly those that have fee arrangements and related party relationships. The ASU is effective for fiscal years, and for interim periods within those fiscal years, beginning after December 15, 2015, with early adoption permitted. A reporting entity may apply the amendments in the ASU using: (i) a modified retrospective approach by recording a cumulative-effect adjustment to equity as of the beginning of the fiscal year of adoption; or (ii) by applying the amendments retrospectively. We adopted this standard during the first quarter of 2016. The guidance does not amend the existing disclosure requirements for variable interest entities (“VIEs”) or voting interest model entities. The guidance, however, modified the requirements to qualify under the voting interest model. Under the revised guidance, the Operating Partnership will be a variable interest entity of the Company and the Company is considered the primary beneficiary. As the Operating Partnership is already consolidated in the balance sheets of the Company, the identification of this entity as a variable interest entity has no impact on the consolidated financial statements of the Company. There were no other legal entities qualifying under the scope of the revised guidance that were consolidated as a result of the adoption of this guidance. In addition, there were no other voting interest entities under prior existing guidance determined to be variable interest entities under the revised guidance.

In April 2015, the FASB issued an ASU that requires reporting entities to present debt issuance cost related to a note as a direct deduction from the face amount of that note presented in the balance sheet. The ASU requires the amortization of debt issuance costs presented as interest expense. The ASU is effective for fiscal years, and for interim periods within those fiscal years, beginning after December 15, 2015, with early adoption permitted. A reporting entity may apply the amendments in the ASU retrospectively to all prior periods. We adopted this standard during the first quarter of 2016, resulting in the presentation of current period and prior period debt issuance costs associated with our secured notes payable, unsecured notes payable and unsecured line of credit as a direct reduction from the carrying amount of the related debt instrument. These costs were previously included in other assets, net in our consolidated balance sheets.

In February 2016, the FASB issued an ASU that establishes a right-of-use model that requires a lessee to record a right-of-use asset and a lease liability on the balance sheet for all leases with terms longer than twelve months. The accounting applied by lessors under this ASU is largely unchanged. Leases will be either classified as sales-type, finance or operating, with classification affecting the pattern of expense recognition in the income statement. The ASU also requires significant additional disclosures about the amount, timing and uncertainty of cash flows from leases. The ASU is effective for fiscal years, and for interim periods within those fiscal years, beginning after December 15, 2018. A modified retrospective transition approach is required for lessors for sales-type, direct financing, and operating leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements, with certain practical expedients available. We are in the process of evaluating the impact this pronouncement will have on our consolidated financial statements.
