Accounting Policies [Abstract] |
Business and Organization | 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”). The company’s operations are carried on through our Operating Partnership and its subsidiaries, including our taxable real estate investment trust (“REIT”) subsidiary (“TRS”). Since the formation of our Operating Partnership, the company has controlled our Operating Partnership as its general partner and has consolidated its assets, liabilities and results of operations. We are a full service, vertically integrated, and self-administered REIT with approximately 231 employees providing substantial in-house expertise in asset management, property management, property development, leasing, tenant improvement construction, acquisitions, repositioning, redevelopment and financing. As of September 30, 2025, we owned or had a controlling interest in 31 office, retail, multifamily and mixed-use operating properties, the operations of which we consolidate. Additionally, as of September 30, 2025, we owned land at two of our properties that we classify as held for development and/or construction in progress.

Basis of Presentation | 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. The company follows the Financial Accounting Standards Board (the “FASB”) guidance for determining whether an entity is a variable interest entity (“VIE”), which requires the performance of a qualitative rather than a quantitative analysis to determine the primary beneficiary of a VIE. Under this guidance, an entity would be required to consolidate a VIE if it has (i) the power to direct the activities that most significantly impact the entity’s economic performance and (ii) the obligation to absorb losses of the VIE or the right to receive benefits from the VIE that could be significant to the VIE. American Assets Trust, Inc. has concluded that the Operating Partnership is a VIE, and because American Assets Trust, Inc. has both the power and the rights to control the Operating Partnership, American Assets Trust, Inc. is the primary beneficiary and is required to continue to consolidate the Operating Partnership. Substantially all of the assets and liabilities of the company are related to the Operating Partnership VIE. All intercompany transactions and balances are eliminated in consolidation.
Basis of Accounting | 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, 2024.
Use of Estimates | 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.
Segment Information | Segment Information Segment information is prepared on the same basis that our management reviews information for operational decision-making purposes. We operate in four reportable 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.
Revenue Recognition and Accounts Receivable | Revenue Recognition and Accounts Receivable Our leases with tenants are classified as operating leases. Substantially all such leases contain fixed rent escalations which occur at specified times during the term of the lease. Base rents are recognized on a straight-line basis from when the tenant controls the space through the term of the related lease, net of valuation adjustments, based on management's assessment of credit, collection and other business risks. Hotel revenue recognized at Waikiki Beach Walk Embassy Suites™ Hotel is in accordance with Accounting Standards Codification (“ASC”) 606, “Revenue from Contracts with Customers,” and is included within rental income on the statement of comprehensive income. We make estimates of the collectability of our current accounts receivable and straight-line rents receivable which require significant judgment by management. The collectability of receivables is affected by numerous different factors including current economic conditions, the impact of tenant bankruptcies, the status of collectability of current cash rents receivable, tenants' recent and historical financial and operating results, changes in our tenants' credit ratings, communications between our operating personnel and tenants, the extent of security deposits and letters of credit held with respect to tenants, and the ability of tenants to perform under the terms of their lease agreement. The provision for doubtful accounts at September 30, 2025 and December 31, 2024 was approximately $1.4 million and $2.0 million, respectively.
Other Revenue Recognition Policies | Other revenue recognition policies When we enter into a transaction to sell a property or a portion of a property, we evaluate the recognition of the sale under ASC 610-20, “Other Income - Gains and Losses from the Derecognition of Nonfinancial Assets,” to determine whether and when control transfers and how to measure the associated gain or loss. We determine the transaction price based on the consideration we expect to receive. Variable consideration is included in the transaction price to the extent it is probable that a significant reversal of a gain recognized will not occur. We analyze the risk of a significant gain reversal and if necessary limit the amount of variable consideration recognized in order to mitigate this risk. The estimation of variable consideration requires us to make assumptions and apply significant judgment.
Recent Accounting Pronouncements | Recent Accounting Pronouncements In November 2023, the FASB issued Accounting Standards Update (“ASU”) 2023-07, Improvements to Reportable Segment Disclosures, that requires the quarterly disclosure of segment expenses if they are (i) significant to the segment, (ii) regularly provided to the chief operating decision maker (“CODM”), and (iii) included in each reported measure of a segment’s profit or loss. In addition, this ASU requires an annual disclosure of the CODM’s title and a description of how the CODM uses the segment’s profit/loss measure to assess segment performance and to allocate resources. We retrospectively adopted ASU 2023-07 during the year ended December 31, 2024. While the adoption has no impact on our financial statements, it has resulted in incremental disclosures within the footnotes to our consolidated financial statements (see Note 17 Segment Reporting). In December 2023, the FASB issued ASU 2023-09, Improvements to Income Tax Disclosures. This pronouncement requires enhanced income tax disclosures, primarily through standardization and disaggregation of rate reconciliation categories and income taxes paid by jurisdiction. This pronouncement is effective for annual periods in fiscal years beginning after December 15, 2024, and should be applied either prospectively or retrospectively. We are currently evaluating the impact this pronouncement will have on our disclosures. In November 2024, the FASB issued ASU 2024-03, Income Statement-Reporting Comprehensive Income-Expense Disaggregation Disclosures. This pronouncement requires public entities to disclose additional information about specific expense categories in the notes to the financial statements on an interim and annual basis. ASU 2024-03 is effective for fiscal years beginning after December 15, 2026, and for interim periods beginning after December 15, 2027, and should be applied either prospectively or retrospectively, with early adoption permitted. The Company is currently evaluating the impact of adopting ASU 2024-03.
Fair Value Measurement | A fair value measurement is based on the assumptions that market participants would use in pricing an asset or liability. The hierarchy for inputs used in measuring fair value is as follows: 1.Level 1 Inputs—quoted prices in active markets for identical assets or liabilities 2.Level 2 Inputs—observable inputs other than quoted prices in active markets for identical assets and liabilities 3.Level 3 Inputs—unobservable inputs The carrying values of cash and cash equivalents, accounts receivable, accounts payable and accrued liabilities are reasonable estimates of fair value, using Level 1 inputs, because of the short-term nature of these instruments. In certain cases, the inputs used to measure fair value may fall into different levels of the fair value hierarchy. In such cases, for disclosure purposes, the level within which the fair value measurement is categorized is based on the lowest level input that is significant to the fair value measurement. We measure the fair value of our deferred compensation liability, which is included in other liabilities and deferred credits on the consolidated balance sheet, on a recurring basis using Level 2 inputs. We measure the fair value of this liability based on prices provided by independent market participants that are based on observable inputs using market-based valuation techniques. The fair value of the interest rate swap agreements are based on the estimated amounts we would receive or pay to terminate the contract at the reporting date and are determined using interest rate pricing models and interest rate related observable inputs. The changes in the fair value of the derivatives that are designated as cash flow hedges are being recorded in accumulated other comprehensive income (loss) and will be subsequently reclassified into earnings during the period in which the hedged forecasted transaction affects earnings. We incorporate credit valuation adjustments to appropriately reflect both our own non-performance risk and the respective counterparty’s non-performance risk in the fair value measurements. In adjusting the fair value of our derivative contracts for the effect of non-performance risk, we considered the impact of netting and any applicable credit enhancements, such as collateral postings, thresholds, mutual puts, and guarantees. Although we have determined that the majority of the inputs used to value our derivatives fall within Level 2 of the fair value hierarchy, the credit valuation adjustments associated with our derivatives utilize Level 3 inputs, such as estimates of current credit spreads to evaluate the likelihood of default by itself and its counterparties. However, as of September 30, 2025 we have assessed the significance of the impact of the credit valuation adjustments on the overall valuation of our derivative position and have determined that the credit valuation adjustments are not significant to the overall valuation of our derivative. As a result, we have determined that our derivative valuation in its entirety is classified in Level 2 of the fair value hierarchy.
