EXPLANATORY NOTE

This report combines the quarterly reports on Form 10-Q for the quarter ended March 31, 2024 of American Assets Trust, Inc., a Maryland corporation, and American Assets Trust, L.P., a Maryland limited partnership, of which American Assets Trust, Inc. is the parent company and sole general partner. Unless otherwise indicated or unless the context requires otherwise, all references in this report to “we,” “us,” “our” or “the company” refer to American Assets Trust, Inc. together with its consolidated subsidiaries, including American Assets Trust, L.P. Unless otherwise indicated or unless the context requires otherwise, all references in this report to “our Operating Partnership” or “the Operating Partnership” refer to American Assets Trust, L.P. together with its consolidated subsidiaries.

American Assets Trust, Inc. operates as a real estate investment trust, or REIT, and is the sole general partner of the Operating Partnership. As of March 31, 2024, American Assets Trust, Inc. owned an approximate 78.8% partnership interest in the Operating Partnership. The remaining approximately 21.2% partnership interests are owned by non-affiliated investors and certain of our directors and executive officers. As the sole general partner of the Operating Partnership, American Assets Trust, Inc. has full, exclusive and complete authority and control over the Operating Partnership’s day-to-day management and business, can cause it to enter into certain major transactions, including acquisitions, dispositions and debt refinancings, and can cause changes in its line of business, capital structure and distribution policies.

American Assets Trust, Inc. believes that combining the quarterly reports on Form 10-Q of American Assets Trust, Inc. and the Operating Partnership into a single report will result in the following benefits:

•better reflects how management and the analyst community view the business as a single operating unit;

•enhance investors' understanding of American Assets Trust, Inc. and the Operating Partnership by enabling them to view the business as a whole and in the same manner as management;

•greater efficiency for American Assets Trust, Inc. and the Operating Partnership and resulting savings in time, effort and expense; and

•greater efficiency for investors by reducing duplicative disclosure by providing a single document for their review.

The management of American Assets Trust, Inc. and the Operating Partnership is the same and operates American Assets Trust, Inc. and the Operating Partnership as one enterprise.

There are certain differences between American Assets Trust, Inc. and the Operating Partnership, which are reflected in the disclosures in this report. We believe it is important to understand the differences between American Assets Trust, Inc. and the Operating Partnership in the context of how American Assets Trust, Inc. and the Operating Partnership operate as an interrelated consolidated company. American Assets Trust, Inc. is a REIT, whose only material asset is its ownership of partnership interests of the Operating Partnership. As a result, American Assets Trust, Inc. does not conduct business itself, other than acting as the sole general partner of the Operating Partnership, issuing public equity from time to time and guaranteeing certain debt of the Operating Partnership. American Assets Trust, Inc. itself does not hold any indebtedness. The Operating Partnership holds substantially all the assets of the company, directly or indirectly holds the ownership interests in the company's real estate ventures, conducts the operations of the business and is structured as a partnership with no publicly-traded equity. Except for net proceeds from public equity issuances by American Assets Trust, Inc., which are generally contributed to the Operating Partnership in exchange for partnership units, the Operating Partnership generates the capital required by American Assets Trust, Inc.'s business through the Operating Partnership’s operations, by the Operating Partnership’s direct or indirect incurrence of indebtedness or through the issuance of operating partnership units.

Noncontrolling interests and stockholders’ equity and partners’ capital are the main areas of difference between the consolidated financial statements of American Assets Trust, Inc. and those of American Assets Trust, L.P. The partnership interests in the Operating Partnership that are not owned by American Assets Trust, Inc. are accounted for as partners’ capital in the Operating Partnership’s financial statements and as noncontrolling interests in American Assets Trust, Inc.’s financial statements. To help investors understand the significant differences between American Assets Trust, Inc. and the Operating Partnership, this report presents the following separate sections for each of American Assets Trust, Inc. and the Operating Partnership:

•consolidated financial statements;

•the following notes to the consolidated financial statements:

◦Debt;

◦Equity/Partners' Capital; and

◦Earnings Per Share/Unit; and

•Liquidity and Capital Resources in Management's Discussion and Analysis of Financial Condition and Results of Operations.

This report also includes separate Item 4. Controls and Procedures sections and separate Exhibit 31 and 32 certifications for each of American Assets Trust, Inc. and the Operating Partnership in order to establish that the Chief Executive Officer and the Chief Financial Officer of American Assets Trust, Inc. have made the requisite certifications and American Assets Trust, Inc. and the Operating Partnership are compliant with Rule 13a-15 or Rule 15d-15 of the Securities Exchange Act of 1934 and 18 U.S.C. §1350.

NOTE 1. 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”). 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 230 employees providing substantial in-house expertise in asset management, property management, property development, leasing, tenant improvement construction, acquisitions, repositioning, redevelopment and financing.

As of March 31, 2024, 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 March 31, 2024, we owned land at three of our properties that we classify as held for development and/or construction in progress.

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”) and 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.

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, 2023.

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, number of units, 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, 2023. There have been no changes to our significant accounting policies during the three months ended March 31, 2024.

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 office real estate, retail real estate, multifamily real estate and mixed-use real estate. 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 retail segment primarily include rental of retail 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

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.

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 March 31, 2024 and December 31, 2023 was approximately $1.4 million and $1.4 million, respectively.

Recent Accounting Pronouncements

In November 2023, the FASB issued Accounting Standards Update (“ASU”) 2023-07, Improvements to Reportable Segment Disclosures. The pronouncement requires disclosure of significant segment expenses that are regularly provided to the chief operating decision maker and included within the segment measure of profit or loss. The pronouncement will be applied retrospectively and is effective for annual reporting periods in fiscal years beginning after December 15, 2023, and interim reporting periods in fiscal years beginning after December 31, 2024. We are currently evaluating the impact this pronouncement will have on our disclosures.

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.

NOTE 2. ACQUIRED IN-PLACE LEASES AND ABOVE/BELOW MARKET LEASES

The following summarizes our acquired lease intangibles and leasing costs, which are included in other assets and other liabilities and deferred credits, as of March 31, 2024 and December 31, 2023 (in thousands):

Acquired lease intangible liabilities, net	$	15,785	$	16,537

NOTE 3. FAIR VALUE OF FINANCIAL INSTRUMENTS

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, restricted cash, 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 March 31, 2024 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.

A summary of our financial liabilities that are measured at fair value on a recurring basis, by level within the fair value hierarchy is as follows (in thousands):

	March 31, 2024								December 31, 2023
	Level 1		Level 2		Level 3		Total		Level 1		Level 2		Level 3		Total
Deferred compensation liability	$	—	$	2,622	$	—	$	2,622	$	—	$	2,627	$	—	$	2,627
Interest rate swap asset	$	—	$	9,355	$	—	$	9,355	$	—	$	7,963	$	—	$	7,963
Interest rate swap liability	$	—	$	—	$	—	$	—	$	—	$	—	$	—	$	—

 The fair value of our secured notes payable and unsecured senior guaranteed notes are sensitive to fluctuations in interest rates. Discounted cash flow analysis using observable market interest rates (Level 2) is generally used to estimate the fair value of our secured notes payable, using rates ranging from 5.7% to 6.5%.

Considerable judgment is necessary to estimate the fair value of financial instruments. The estimates of fair value presented herein are not necessarily indicative of the amounts that could be realized upon disposition of the financial instruments. The carrying values of our term loans set forth below are deemed to be at fair value since the outstanding debt is directly tied to monthly SOFR. A summary of the carrying amount and fair value of our secured financial instruments, all of which are based on Level 2 inputs, is as follows (in thousands):  

	March 31, 2024				December 31, 2023
	Carrying Value		Fair Value		Carrying Value		Fair Value
Secured notes payable, net	$	74,691	$	74,115	$	74,669	$	74,804
Unsecured term loans, net	$	323,781	$	325,000	$	323,491	$	325,000
Unsecured senior guaranteed notes, net	$	798,875	$	769,152	$	798,772	$	770,998
Senior unsecured notes, net	$	492,952	$	406,635	$	492,694	$	405,860

NOTE 4. DERIVATIVE AND HEDGING ACTIVITIES

Our objectives in using interest rate derivatives are to add stability to interest expense and to manage our exposure to interest rate movements.  To accomplish these objectives, we primarily use interest rate swaps as part of our interest rate risk management strategy.  Interest rate swaps designated as cash flow hedges involve the receipt of variable-rate amounts from a counterparty in exchange for us making fixed-rate payments over the life of the agreements without exchange of the underlying notional amount.

The following is a summary of the terms of our outstanding interest rate swaps as of March 31, 2024 (dollars in thousands):

Swap Counterparty	Notional Amount		Effective Date	Maturity Date	Fair Value
Bank of America, N.A.	$	50,000	1/14/2022	1/5/2027	$	3,738
Wells Fargo Bank, N.A.	$	50,000	1/14/2022	1/5/2027	$	3,899
Wells Fargo Bank, N.A.	$	150,000	1/5/2023	1/5/2025	$	1,352
Mizuho Capital Markets LLC	$	75,000	1/5/2023	1/5/2025	$	366

The effective portion of changes in the fair value of the derivatives that are designated as cash flow hedges are being recorded in accumulated other comprehensive income and will be subsequently reclassified into earnings during the period in which the hedged forecasted transaction affects earnings for as long as hedged cash flows remain probable. During the next twelve months, we estimate the cash flow hedges in place will reduce interest expense by approximately $0.4 million.

The valuation of these instruments is determined using widely accepted valuation techniques including discounted cash flow analysis on the expected cash flows of the derivative.  This analysis reflects the contractual terms of the derivative, including the period to maturity, and counterparty credit risk and uses observable market-based inputs, including interest rate curves, and implied volatilities.  The fair value of the interest rate swap is determined using the market standard methodology of netting the discounted future fixed cash receipts (or payments) and the discounted expected variable cash payments (or receipts).  The variable cash payments (or receipts) are based on an expectation of future interest rates (forward curves) derived from observable market interest rate curves.

As of March 31, 2024, the Operating Partnership was in compliance with all then in-place 3.375% Senior Notes covenants.

Senior Guaranteed Notes

On October 31, 2014, the Operating Partnership entered into a note purchase agreement (the "Note Purchase Agreement") with a group of institutional purchasers that provided for the private placement of an aggregate of $350 million of senior guaranteed notes, of which (i) $150 million are designated as 4.04% Senior Guaranteed Notes, Series A, due October 31, 2021 (the “Series A Notes”), (ii) $100 million are designated as 4.45% Senior Guaranteed Notes, Series B, due February 2, 2025 (the “Series B Notes”) and (iii) $100 million are designated as 4.50% Senior Guaranteed Notes, Series C, due April 1, 2025 (the “Series C Notes”). The Series A Notes were issued on October 31, 2014, the Series B Notes were issued on February 2, 2015 and the Series C Notes were issued on April 2, 2015. The Series A Notes, the Series B Notes and the Series C Notes will pay interest quarterly on the last day of January, April, July and October until their respective maturities. On January 26, 2021, we repaid the entirety of the $150.0 million Series A Notes with a make-whole payment (as defined in the Note Purchase Agreement) of approximately $3.9 million.

On March 1, 2017, the Operating Partnership entered into a Note Purchase Agreement for the private placement of $250 million of 4.29% Senior Guaranteed Notes, Series D, due March 1, 2027 (the "Series D Notes"). The Series D Notes were issued on March 1, 2017 and pay interest quarterly on the last day of January, April, July and October until their respective maturities.

On May 23, 2017, the Operating Partnership entered into a Note Purchase Agreement for the private placement of $100 million of 4.24% Senior Guaranteed Notes, Series E, due May 23, 2029 (the "Series E Notes"). The Series E Notes were issued on May 23, 2017 and pay interest semi-annually on the 23rd of May and November until their respective maturities.

On July 19, 2017, the Operating Partnership entered into a Note Purchase Agreement for the private placement of $100 million of 3.78% Senior Guaranteed Notes, Series F, due July 19, 2024 (the "Series F Notes"). The Series F Notes were issued on July 19, 2017 and pay interest semi-annually on the 31st of January and July until their respective maturities.

On July 30, 2019, the Operating Partnership entered into a Note Purchase Agreement for the private placement of $150 million of 3.91% Senior Guaranteed Notes, Series G, due July 30, 2030 (the "Series G Notes" and collectively with the Series A Notes, Series B Notes, Series C Notes, Series D Notes, Series E Notes, and Series G Notes are referred to herein as, the “Notes".) The Series G Notes were issued on July 30, 2019 and pay interest semi-annually on the 30th of July and January until their maturity.

The Operating Partnership may prepay at any time all, or from time to time any part of, the Notes, in an amount not less than 5% of the aggregate principal amount of any series of the Notes then outstanding in the case of a partial prepayment, at 100% of the principal amount so prepaid plus a make-whole amount.

The Note Purchase Agreements contain a number of customary financial covenants, including, without limitation, tangible net worth thresholds, secured and unsecured leverage ratios and fixed charge coverage ratios. Subject to the terms of the Note Purchase Agreement and the Notes, upon certain events of default, including, but not limited to, (i) a default in the payment of any principal, Make-Whole Amount or interest under the Notes, and (ii) a default in the payment of certain other indebtedness by us or our subsidiaries, the principal, accrued and unpaid interest, and the make-whole amount on the outstanding Notes will become due and payable at the option of the purchasers.

The Operating Partnership's obligations under the Notes are fully and unconditionally guaranteed by the Operating Partnership and certain of the Operating Partnership's subsidiaries.

Certain loans require the Operating Partnership to comply with various financial covenants, including the maintenance of minimum debt coverage ratios. As of March 31, 2024, the Operating Partnership was in compliance with all loan covenants.

Third Amended and Restated Credit Facility

On January 5, 2022, the Operating Partnership entered into the third amended and restated credit facility (the “Third Amended and Restated Credit Facility”) , which amended and restated our then-existing credit facility. The Third Amended and Restated Credit Facility provides for aggregate, unsecured borrowings of up to $500 million, consisting of a revolving line of credit of $400 million (the “Revolver Loan”) and a term loan of $100 million (“Term Loan A”). The Revolver Loan initially matures on January 5, 2026, subject to two, six-month extension options. Term Loan A matures on January 5, 2027, with no further extension options. As of March 31, 2024, the entirety of the principal amount of Term Loan A was outstanding, there were no amounts outstanding under the Revolver Loan, and the Operating Partnership had incurred approximately $1.13 million of net debt issuance costs which are recorded in other assets, net on the consolidated balance sheet. For the three months ended March 31, 2024, the weighted average interest rate on the Revolver Loan was 6.54%.

Borrowings under the Third Amended and Restated Credit Agreement bear interest at floating rates equal to, at the Operating Partnership’s option, either (1) the applicable SOFR, plus the applicable SOFR Adjustment and a spread which ranges from (a) 1.05%-1.50% (with respect to the Revolver Loan) and (b) 1.20% to 1.70% (with respect to Term Loan A), in each case based on our consolidated leverage ratio, or (2) a base rate equal to the highest of (a) the prime rate, (b) the federal funds rate plus 50 bps, (c) the Term SOFR Screen Rate with a term of one month plus 100 bps and (d) 1.00%, plus a spread which ranges from (i) 0.10%-0.50% (with respect to the Revolver Loan) and (ii) 0.20% to 0.70% (with respect to Term Loan A), in each case based on our consolidated leverage ratio. On January 14, 2022, the Operating Partnership entered into an interest rate swap agreement intended to fix the interest rate associated with the Term Loan A at approximately 2.70% through January 5, 2027, subject to adjustments based on our consolidated leverage ratio.

The Third Amended and Restated Credit Facility includes a number of customary financial covenants, including:

•A maximum leverage ratio (defined as total indebtedness net of certain cash and cash equivalents to total asset

value) of 60%,

•A maximum secured leverage ratio (defined as total secured debt to secured total asset value) of 40%,

•A minimum fixed charge coverage ratio (defined as consolidated earnings before interest, taxes, depreciation and

amortization to consolidated fixed charges) of 1.50x,

•A minimum unsecured interest coverage ratio of 1.75x,

•A maximum unsecured leverage ratio of 60%, and

•Recourse indebtedness at any time cannot exceed 15% of total asset value.

The Third Amended and Restated Credit Facility also provides that our annual distributions may not exceed the greater of (1) 95% of our funds from operations (“FFO”) or (2) the amount required for us to (a) qualify and maintain our REIT status and (b) avoid the payment of federal or state income or excise tax. If certain events of default exist or would result from a distribution, we may be precluded from making distributions other than those necessary to qualify and maintain our status as a REIT.

As of March 31, 2024, the Operating Partnership was in compliance with all then in-place Third Amended and Restated Credit Facility covenants.

Amended and Restated Term Loan Agreement

On January 5, 2023, we entered into the amended and restated term loan agreement (the “Amended and Restated Term Loan Agreement”), which amended and restated our then-existing term loan agreement. The Amended and Restated Term Loan Agreement provides to the Operating Partnership a term loan of $150 million (“Term Loan B”) and a term loan of $75 million (“Term Loan C”), each maturing on January 5, 2025, with one, twelve-month extension option, subject to certain conditions. As of March 31, 2024, the entirety of the principal amounts of Term Loan B and Term Loan C were outstanding.

Borrowings under the Amended and Restated Term Loan Agreement bear interest at floating rates equal to, at the Operating Partnership’s option, either (1) the applicable SOFR, plus a SOFR adjustment and a spread (based on the Operating Partnership’s consolidated leverage ratio and applicable year of Term Loan B and Term Loan C) ranging from 1.20% to 1.90%, or (2) a base rate equal to the highest of (a) 0%, (b) the prime rate, (c) the federal funds rate plus 50 bps and (d) the one-month SOFR, plus a SOFR adjustment and 100 bps, plus, in each case, a spread (based on the Operating Partnership’s consolidated

leverage ratio and applicable year of Term Loan B and Term Loan C) ranging from 0.20% to 0.90%. Additionally, the Operating Partnership may elect for borrowings to bear interest based on a ratings-based pricing grid based on the Operating Partnership’s then-applicable investment grade debt ratings under the terms set forth in the Amended and Restated Term Loan Agreement. Prior to entering into the Amended and Restated Term Loan Agreement, the Operating Partnership entered into interest rate swap agreements that are intended to fix the interest rate associated with Term Loan B and Term Loan C at approximately (1) 5.47% for the first year of Term Loan B and Term Loan C and (2) 5.57% for the second year of Term Loan B and Term Loan C, subject to adjustments based on the company’s consolidated leverage ratio.

The Amended and Restated Term Loan Agreement contains a number of customary financial covenants, including, without limitation, tangible net worth thresholds, secured and unsecured leverage ratios and fixed charge coverage ratios. Subject to the terms of the Amended and Restated Term Loan Agreement, upon certain events of default, including, but not limited to, (i) a default in the payment of any principal or interest under Term Loan B or Term Loan C, and (ii) a default in the payment of certain other indebtedness of the Operating Partnership, the company or their subsidiaries, the principal and accrued and unpaid interest and prepayment penalties on the outstanding Term Loan B or Term Loan C will become due and payable at the option of the lenders.

NOTE 8. PARTNERS' CAPITAL OF AMERICAN ASSETS TRUST, L.P.

Noncontrolling interests in our Operating Partnership are interests in the Operating Partnership that are not owned by us. Noncontrolling interests consisted of 16,181,537 common units (the “noncontrolling common units”), and represented approximately 21.2% of the ownership interests in our Operating Partnership at March 31, 2024. Common units and shares of our common stock have essentially the same economic characteristics in that common units and shares of our common stock share equally in the total net income or loss distributions of our Operating Partnership. Investors who own common units have the right to cause our Operating Partnership to redeem any or all of their common units for cash equal to the then-current market value of one share of our common stock, or, at our election, shares of our common stock on a one-for-one basis.

During the three months ended March 31, 2024, no common units were converted into shares of our common stock.

Earnings Per Unit of the Operating Partnership

Basic earnings per unit (“EPU”) of the Operating Partnership is computed by dividing income applicable to unitholders by the weighted average Operating Partnership units outstanding, as adjusted for the effect of participating securities. Operating Partnership units granted in equity-based payment transactions that have non-forfeitable dividend equivalent rights are considered participating securities prior to vesting. The impact of unvested Operating Partnership unit awards on EPU has been calculated using the two-class method whereby earnings are allocated to the unvested Operating Partnership unit awards based on distributions and the unvested Operating Partnership units’ participation rights in undistributed earnings.

The calculation of diluted EPU for the three months ended March 31, 2024 and 2023 does not include the weighted average of 585,210 and 573,253 unvested outstanding Operating Partnership units, respectively, as these equity securities are either considered contingently issuable or the effect of including these equity securities was anti-dilutive to income from continuing operations and net income attributable to the unitholders.

NOTE 9. EQUITY OF AMERICAN ASSETS TRUST, INC.

Stockholders' Equity

On December 3, 2021, we entered into an at-the-market ("ATM") equity program with five sales agents in which we may, from time to time, offer and sell shares of our common stock having an aggregate offering price of up to $250 million. The sales of shares of our common stock made through the ATM equity program, as amended, are made in "at-the-market" offerings as defined in Rule 415 of the Securities Act of 1933, as amended. For the three months ended March 31, 2024, no shares of common stock were sold through the ATM equity program.

(Unaudited)

We intend to use the net proceeds from the ATM equity program to fund our development or redevelopment activities, repay amounts outstanding from time to time under our revolving line of credit or other debt financing obligations, fund potential acquisition opportunities and/or for general corporate purposes. As of March 31, 2024, we had the capacity to issue up to $250 million in shares of our common stock under our current ATM equity program. Actual future sales will depend on a variety of factors including, but not limited to, market conditions, the trading price of our common stock and our capital needs. As of March 31, 2024, we have no obligation to sell the remaining shares available for sale under the ATM equity program.

Dividends

The following table lists the dividends declared and paid on our shares of common stock and noncontrolling common units during the three months ended March 31, 2024:

Period	Amount per Share/Unit		Period Covered	Dividend Paid Date
First Quarter 2024	$	0.335	January 1, 2024 to March 31, 2024	March 21, 2024

Taxability of Dividends

Earnings and profits, which determine the taxability of distributions to stockholders and holders of common units, may differ from income reported for financial reporting purposes due to the differences for federal income tax purposes in the treatment of revenue recognition and compensation expense and in the basis of depreciable assets and estimated useful lives used to compute depreciation.

Stock-Based Compensation

We follow the FASB guidance related to stock-based compensation which establishes financial accounting and reporting standards for stock-based employee compensation plans, including all arrangements by which employees receive shares of stock or other equity instruments of the employer.  The guidance also defines a fair value-based method of accounting for an employee stock award or similar equity instrument.

The following table summarizes the activity of restricted stock awards during the three months ended March 31, 2024:

	Units	Weighted Average Grant Date Fair Value
Nonvested at January 1, 2024	585,865	$	17.95
Granted	—	—
Vested	—	—
Forfeited	(1,295)	17.32
Nonvested at March 31, 2024	584,570	$	17.95

We recognize noncash compensation expense ratably over the vesting period, and accordingly, we recognized $1.6 million and $2.0 million in noncash compensation expense for the three months ended March 31, 2024 and 2023, respectively, which is included in general and administrative expenses on the consolidated statements of comprehensive income. Unrecognized compensation expense was $7.1 million at March 31, 2024.

Earnings Per Share

We have calculated earnings per share (“EPS”) under the two-class method. The two-class method is an earnings allocation methodology whereby EPS for each class of common stock and participating security is calculated according to dividends declared and participation rights in undistributed earnings. The weighted average unvested shares outstanding, which are considered participating securities, were 585,210 and 573,253 for the three months ended March 31, 2024 and 2023, respectively. Therefore, we have allocated our earnings for basic and diluted EPS between common shares and unvested shares as these unvested shares have nonforfeitable dividend equivalent rights.

Diluted EPS is calculated by dividing the net income applicable to common stockholders for the period by the weighted average number of common and dilutive instruments outstanding during the period using the treasury stock method. For the three months ended March 31, 2024 and 2023, diluted shares exclude incentive restricted stock as these awards are considered contingently issuable. Additionally, the unvested restricted stock awards subject to time vesting are anti-dilutive for all periods presented, and accordingly, have been excluded from the weighted average common shares used to compute diluted EPS.

The computation of basic and diluted EPS is presented below (dollars in thousands, except share and per share amounts):

NOTE 10. INCOME TAXES

We elected to be taxed as a REIT and operate in a manner that allows us to qualify as a REIT for federal income tax purposes commencing with our initial taxable year. As a REIT, we are generally not subject to corporate level income tax on the earnings distributed currently to our stockholders that we derive from our REIT qualifying activities. Taxable income from non-REIT activities managed through our TRS is subject to federal and state income taxes.

We lease our hotel property to a wholly owned TRS that is subject to federal and state income taxes. We account for income taxes using the asset and liability method, under which deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between GAAP carrying amounts and their respective tax bases. Additionally, we classify certain state taxes as income taxes for financial reporting purposes in accordance with ASC Topic 740, Income Taxes.

A deferred tax asset is included in our consolidated balance sheets of $0.9 million and $0.9 million, and a deferred tax liability is included in our consolidated balance sheets of $0.8 million and $0.8 million as of March 31, 2024 and December 31,

Income tax expense is recorded in other income, net on our consolidated statements of comprehensive income. For the three months ended March 31, 2024, we recorded income tax expense of $0.3 million. For the three months ended March 31, 2023, we recorded income tax expense of $0.3 million.

NOTE 11. COMMITMENTS AND CONTINGENCIES

Legal

We are sometimes involved in various disputes, lawsuits, warranty claims, environmental considerations, and other matters arising in the ordinary course of business. Management makes assumptions and estimates concerning the likelihood and amount of any potential loss relating to these matters.

We are currently a party to various legal proceedings. We accrue a liability for litigation if an unfavorable outcome is probable and the amount of loss can be reasonably estimated. If an unfavorable outcome is probable and a reasonable estimate of the loss is a range, we accrue the best estimate within the range; however, if no amount within the range is a better estimate than any other amount, the minimum amount within the range is accrued. Legal fees related to litigation are expensed as incurred. We do not believe that the ultimate outcome of these matters, either individually or in the aggregate, could have a material adverse effect on our financial position or overall trends in results of operations; however, litigation is subject to inherent uncertainties. Also, under our leases, tenants are typically obligated to indemnify us from and against all liabilities, costs and expenses imposed upon or asserted against us as owner of the properties due to certain matters relating to the operation of the properties by the tenant.

Commitments

See Footnote 12 for description of our leases, as a lessee.

We have management agreements with Outrigger Hotels & Resorts or an affiliate thereof (“Outrigger”) pursuant to which Outrigger manages each of the retail and hotel portions of the Waikiki Beach Walk property. Under the management agreement with Outrigger relating to the retail portion of Waikiki Beach Walk (the “retail management agreement”), we pay Outrigger a monthly management fee of 3.0% of net revenues from the retail portion of Waikiki Beach Walk. Pursuant to the terms of the retail management agreement, if the agreement is terminated in certain instances, including our election not to repair damage or destruction at the property, a condemnation or our failure to make required working capital infusions, we would be obligated to pay Outrigger a termination fee equal to the sum of the management fees paid for the two months immediately preceding the termination date. The retail management agreement may not be terminated by us or by Outrigger without cause. Under our management agreement with Outrigger relating to the hotel portion of Waikiki Beach Walk (the “hotel management agreement”), we pay Outrigger a monthly management fee of 6.0% of the hotel's gross operating profit, as well as 3.0% of the hotel's gross revenues; provided that the aggregate management fee payable to Outrigger for any year shall not exceed 3.5% of the hotel's gross revenues for such fiscal year. The hotel management agreement may not be terminated by us or by Outrigger without cause. Additionally, we have a management agreement with Outrigger pursuant to which Outrigger manages our Waikele Center and Shops at Kalakaua. In connection with such management agreement, we pay Outrigger a fixed management fee of $12,000 per month in the aggregate plus additional amounts for any lease renewal services provided by Outrigger at our request. This management agreement can be terminated by us at any time and for any reason on 30 days' notice without any cancellation or termination fees.

A wholly owned subsidiary of our Operating Partnership, WBW Hotel Lessee LLC, entered into a franchise license agreement with Embassy Suites Franchise LLC, the franchisor of the brand “Embassy Suites™,” to obtain the non-exclusive right to operate the hotel under the Embassy SuitesTM brand for 20 years. The franchise license agreement provides that WBW Hotel Lessee LLC must comply with certain management, operational, record keeping, accounting, reporting and marketing standards and procedures. In connection with this agreement, we are also subject to the terms of a product improvement plan pursuant to which we expect to undertake certain actions to ensure that our hotel's infrastructure is maintained in compliance with the franchisor's brand standards. In addition, we must pay to Embassy Suites Franchise LLC a monthly franchise royalty fee equal to 5.0% of the hotel's gross room revenue, as well as a monthly program fee equal to 4.0% of the hotel's gross room revenue. If the franchise license is terminated due to our failure to make required improvements or to otherwise comply with its terms, we may be liable to the franchisor for a termination payment, which could be as high as $7.9 million based on operating performance through March 31, 2024.

Our Del Monte Center property has ongoing environmental remediation related to ground water contamination. The environmental issue existed at purchase and remains in remediation. The final stages of the remediation will include routine, long term ground monitoring by the appropriate regulatory agency over the next several years. The work performed is financed through an escrow account funded by the seller upon purchase of Del Monte Center. We believe the funds in the escrow account are sufficient for the remaining work to be performed. However, if further work is required that costs more than the remaining escrow funds, we may be required to pay such overage, although we may have a contractual claim for such costs against the prior owner or our environmental remediation consultant.

Concentrations of Credit Risk

Our properties are located in Southern California, Northern California, Washington, Oregon, Texas and Hawaii. The ability of the tenants to honor the terms of their respective leases is dependent upon the economic, regulatory, social, and health factors affecting the markets in which the tenants operate. Fifteen of our consolidated properties are located in Southern California, which exposes us to greater economic risks than if we owned a more geographically diverse portfolio. Tenants in the office industry accounted for 46.7% of total revenues for the three months ended March 31, 2024. This makes us susceptible to demand for office rental space and subject to the risks associated with an investment in real estate with a concentration of tenants in the office industry. Furthermore, tenants in the retail industry accounted for 23.5% of total revenues for the three months ended March 31, 2024. This makes us susceptible to demand for retail rental space and subject to the risks associated with an investment in real estate with a concentration of tenants in the retail industry. For the three months ended March 31, 2024 and 2023, no tenant accounted for more than 10% of our total rental revenue.

NOTE 12. LEASES

Lessor Operating Leases

We determine if an arrangement is a lease at inception. Our lease agreements are generally for real estate, and the determination of whether such agreements contain leases generally does not require significant estimates or judgments. We lease real estate under operating leases.

Our leases with office, retail, mixed-use and residential tenants are classified as operating leases. Leases at our office and retail properties and the retail portion of our mixed-use property generally range from three years to ten years (certain leases with anchor tenants may be longer), and in addition to minimum rents, usually provide for cost recoveries for the tenant’s share of certain operating costs. Our leases may also include variable lease payments in the form of percentage rents based on the tenant’s level of sales achieved in excess of a breakpoint threshold. Leases on apartments generally range from seven months to fifteen months, with a majority having 12-month lease terms. Rooms at the hotel portion of our mixed-use property are rented on a nightly basis.

Leases at our office and retail properties and the retail portion of our mixed-use property may contain lease extension options, at our lessee's discretion. The extension options are generally for 3 to 10 years and contain primarily rent at fixed rates or the prevailing market rent. The extension options are generally exercisable 6 to 12 months prior to the expiration of the lease and require the lessee to not be in default of the lease terms.

We attempt to maximize the amount we expect to derive from the underlying real estate property following the end of a lease, to the extent it is not extended.  We maintain a proactive leasing and capital improvement program that, combined with

the quality and locations of our properties, has made our properties attractive to tenants. However, the residual value of a real estate property is still subject to various market-specific, asset-specific, and tenant-specific risks and characteristics. 

As of March 31, 2024, minimum future rentals from noncancelable operating leases, before any reserve for uncollectible amounts and assuming no early lease terminations, at our office and retail properties and the retail portion of our mixed-use property are as follows for the years ended December 31 (in thousands):

 

2024 (nine months ending December 31, 2024)	$	187,854
2025	244,091
2026	229,790
2027	201,651
2028	158,207
Thereafter	246,380
Total	$	1,267,973

The above future minimum rentals exclude residential leases, which typically range from seven months to fifteen months, and exclude the hotel, as rooms are rented on a nightly basis.

Lessee Operating Leases

We determine if an arrangement is a lease at inception. Our lease agreements are generally for real estate, and the determination of whether such agreements contain leases generally does not require significant estimates or judgments. We lease real estate under operating leases.

At The Landmark at One Market, we lease, as lessee, a building adjacent to The Landmark at One Market under an operating lease effective through June 30, 2026, which we have the option to extend until 2031 (the "Annex Lease"). The lease payments under the extension option provided for under the Annex Lease will be equal to the fair rental value at the time the extension option is exercised. The extension option is included in the calculation of the right-of-use asset and lease liability as we are reasonably certain of exercising the extension option.

Our lease agreements do not contain any residual value guarantees or material restrictive covenants. As our leases do not provide an implicit rate, we use our incremental borrowing rate based on the information available at commencement in determining the present value of lease payments.

As of March 31, 2024, current annual payments under the operating leases are as follows for the years ended December 31 (in thousands): 

2024 (nine months ending December 31, 2024)	$	2,584

NOTE 15. RELATED PARTY TRANSACTIONS

During the third quarter of 2020, we entered into a lease with American Assets, Inc. ("AAI"), an entity owned and controlled by Ernest Rady, our Chief Executive Officer and Chairman of the Board, for office space at Torrey Point to replace a previously existing lease with AAI at Torrey Reserve Campus. Rents commenced on March 1, 2021 for an initial lease term of ten years at an average annual rental rate of $0.2 million. Rental revenue recognized on the AAI lease of $0.1 million and $0.1 million for the three months ended March 31, 2024 and 2023, respectively, is included in rental income on the statements of comprehensive income.

On occasion, the company utilizes aircraft services provided by AAI Aviation, Inc. ("AAIA"), an entity owned and controlled by Mr. Rady. For the three months ended March 31, 2024 and 2023, we incurred approximately $0.02 million and $0.1 million of expenses, respectively, related to aircraft services of AAIA or reimbursement to Mr. Rady (or his trust) for use of the aircraft owned by AAIA. These expenses are recorded as general and administrative expenses in our consolidated statements of comprehensive income.

The Waikiki Beach Walk entities have a 47.7% investment in WBW CHP LLC, an entity that was formed to, among other things, construct a chilled water plant to provide air conditioning to the property and other adjacent facilities. The operating expenses of WBW CHP LLC are recovered through reimbursements from its members, and reimbursements to WBW CHP LLC of $0.3 million and $0.3 million for the three months ended March 31, 2024 and 2023, respectively, are included in rental expenses on the consolidated statements of comprehensive income.

NOTE 16. SEGMENT REPORTING

Segment information is prepared on the same basis that our management reviews information for operational decision-making purposes. We operate in four business segments: the acquisition, redevelopment, ownership and management of office real estate, retail real estate, multifamily real estate and mixed-use real estate. 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 retail segment primarily include rental of retail 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.

We evaluate the performance of our segments based on segment profit, which is defined as property revenue less property expenses. We do not use asset information as a measure to assess performance and make decisions to allocate resources. Therefore, depreciation and amortization expense is not allocated among segments. General and administrative expenses, interest expense, depreciation and amortization expense and other income and expense are not included in segment profit as our internal reporting addresses these items on a corporate level.

Segment profit is not a measure of operating income or cash flows from operating activities as measured by GAAP, and it is not indicative of cash available to fund cash needs and should not be considered an alternative to cash flows as a measure of liquidity. Not all companies calculate segment profit in the same manner. We consider segment profit to be an appropriate supplemental measure to net income because it assists both investors and management in understanding the core operations of our properties.

that could impact our future results, performance or transactions, see the section entitled “Item 1A. Risk Factors” contained herein and in our annual report on Form 10-K for the year ended December 31, 2023.

Overview

References to “we,” “our,” “us” and “our company” refer to American Assets Trust, Inc., a Maryland corporation, together with our consolidated subsidiaries, including American Assets Trust, L.P., a Maryland limited partnership, of which we are the sole general partner and which we refer to in this report as our Operating Partnership.

We are a full service, vertically integrated and self-administered REIT that owns, operates, acquires and develops high quality retail, office, multifamily and mixed-use properties in attractive, high-barrier-to-entry markets in Southern California, Northern California, Washington, Oregon, Texas and Hawaii. As of March 31, 2024, our portfolio was comprised of twelve retail shopping centers; twelve office properties; a mixed-use property consisting of a 369-room all-suite hotel and a retail shopping center; and six multifamily properties. Additionally, as of March 31, 2024, we owned land at three of our properties that we classified as held for development and/or construction in progress. Our core markets include San Diego, California; the San Francisco Bay Area, California; Bellevue, Washington; Portland, Oregon and Oahu, Hawaii. We are a Maryland corporation formed on July 16, 2010 to acquire the entities owning various controlling and noncontrolling interests in real estate assets owned and/or managed by Ernest S. Rady or his affiliates, including the Ernest Rady Trust U/D/T March 13, 1983, or the Rady Trust, and did not have any operating activity until the consummation of our initial public offering on January 19, 2011. Our Company, as the sole general partner of our Operating Partnership, has control of our Operating Partnership and owned 78.8% of our Operating Partnership as of March 31, 2024. Accordingly, we consolidate the assets, liabilities and results of operations of our Operating Partnership.

Critical Accounting Policies

We identified certain critical accounting policies that affect certain of our more significant estimates and assumptions used in preparing our consolidated financial statements in our annual report on Form 10-K for the year ended December 31, 2023. We have not made any material changes to these policies during the periods covered by this report, other than those described in Footnote 1.

Same-store

We have provided certain information on a total portfolio, same-store and redevelopment same-store basis. Information provided on a same-store basis includes the results of properties that we owned and operated for the entirety of both periods being compared except for properties for which significant redevelopment or expansion occurred during either of the periods being compared, properties under development, properties classified as held for development and properties classified as discontinued operations. Information provided on a redevelopment same-store basis includes the results of properties undergoing significant redevelopment for the entirety or portion of both periods being compared. Same-store and redevelopment same-store are considered by management to be important measures because they assist in eliminating disparities due to the development, acquisition or disposition of properties during the particular period presented, and thus provide a more consistent performance measure for the comparison of the company's stabilized and redevelopment properties, as applicable. Additionally, redevelopment same-store is considered by management to be an important measure because it assists in evaluating the timing of the start and stabilization of our redevelopment opportunities and the impact that these redevelopments have in enhancing our operating performance.

While there is judgment surrounding changes in designations, we typically reclassify significant development, redevelopment or expansion properties into same-store properties once they are stabilized. Properties are deemed stabilized typically at the earlier of (i) reaching 90% occupancy or (ii) four quarters following a property's inclusion in operating real estate. We typically remove properties from same-store properties when the development, redevelopment or expansion has or is expected to have a significant impact on the property's annualized base rent, occupancy and operating income within the calendar year. Our evaluation of significant impact related to development, redevelopment or expansion activity is based on quantitative and qualitative measures including, but not limited to, the following: the total budgeted cost of planned construction activity compared to the property’s annualized base rent, occupancy and property operating income within the calendar year; percentage of development, redevelopment or expansion square footage to total property square footage; and the ability to maintain historic occupancy and rental rates. In consideration of these measures, we generally remove properties from same-store properties when we see a decline in a property's annualized base rent, occupancy and operating income within the calendar year as a direct result of ongoing redevelopment, development or expansion activity. Acquired properties are classified into same-store properties once we have owned such properties for the entirety of comparable period(s) and the properties are not under significant development or expansion.

30

Below is a summary of our same-store and redevelopment same-store composition for the three months ended March 31, 2024 and 2023. Bel-Spring 520 is classified as a same-store property when compared to the designation for the three months ended March 31, 2023, because the property was acquired on March 8, 2022. The 710 building at Lloyd Portfolio is classified as same-store property when compared to the designation for the three months ended March 31, 2023, because the property has been in operation for a full year since it was placed in service in November of 2022. One Beach Street continues to be identified as a same-store redevelopment property due to significant redevelopment activity.

Retail same-store net operating income decreased approximately 1.1% for the three months ended March 31, 2024 compared to the same period in 2023. Office same-store net operating income increased 1.6% for the three months ended March 31, 2024 compared to the same period in 2023.

	Three Months Ended March 31,
	2024	2023
Same-Store	30	29
Non-Same-Store	1	2
Total Properties	31	31
Redevelopment Same-Store	31	30
Total Development Properties	3	3

Outlook

We seek growth in earnings, funds from operations and cash flows primarily through a combination of the following: growth in our same-store portfolio, growth in our portfolio from property development and redevelopments and expansion of our portfolio through property acquisitions. Our properties are located in some of the nation's most dynamic, high-barrier-to-entry markets primarily in Southern California, Northern California, Washington, Oregon and Hawaii, which allow us to take advantage of redevelopment opportunities that enhance our operating performance through renovation, expansion, reconfiguration and/or retenanting. We evaluate our properties on an ongoing basis to identify these types of opportunities.

We intend to opportunistically pursue projects in our development pipeline, including future phases of La Jolla Commons and Lloyd Portfolio, as well as other redevelopments at Waikele Center and One Beach Street. The commencement of these developments is based on, among other things, market conditions and our evaluation of whether such opportunities would generate appropriate risk-adjusted financial returns. Our redevelopment and development opportunities are subject to various factors, including market conditions and may not ultimately come to fruition.

We continue to review acquisition opportunities in our primary markets that would complement our portfolio and provide long-term growth opportunities. Some of our acquisitions do not initially contribute significantly to earnings growth; however, we believe they provide long-term re-leasing growth, redevelopment opportunities and other strategic opportunities. Any growth from acquisitions is contingent upon our ability to find properties that meet our qualitative standards at prices that meet our financial hurdles. Changes in interest rates may affect our success in achieving earnings growth through acquisitions by affecting both the price that must be paid to acquire a property, as well as our ability to economically finance a property acquisition. Generally, our acquisitions are initially financed by available cash, mortgage loans and/or borrowings under our revolving line of credit, which may be repaid later with funds raised through the issuance of new equity or new long-term debt.

31

Leasing

Our same-store growth is primarily driven by increases in rental rates on new leases and lease renewals and changes in portfolio occupancy. Over the long-term, we believe that the infill nature and strong demographics of our properties provide us with a strategic advantage, allowing us to maintain relatively high occupancy and increase rental rates. Furthermore, we believe the locations of our properties and diversified portfolio will mitigate some of the potentially negative impact of the current economic environment. However, in 2020 through 2022, due to COVID-19, we saw a meaningful negative impact on certain of our tenants' operations and ability to pay rent, primarily in the retail sector. Any reduction in our tenants' abilities to pay base rent, percentage rent or other charges will adversely affect our financial condition and results of operations.

During the three months ended March 31, 2024, we signed 18 office leases for a total of 124,605 square feet of office space including 80,434 square feet of comparable renewal office space leases (leases for which there was a prior tenant), at an average rental rate increase on a cash basis and increase on a GAAP basis of 7.9% and 10.9%, respectively. New office leases for comparable spaces were signed for 22,658 square feet at an average rental rate increase on a cash and GAAP basis of 13.8% and 19.4%, respectively. Renewals for comparable office spaces were signed for 57,776 square feet at an average rental rate increase on a cash basis and increase on a GAAP basis of 6.0% and 8.3%, respectively. Tenant improvements and incentives were $38.22 per square foot of office space for comparable new leases for the three months ended March 31, 2024, mainly due to new tenants at Lloyd District and Torrey Reserve.

During the three months ended March 31, 2024, we signed 30 retail leases for a total of 109,414 square feet of retail space including 103,311 square feet of comparable renewal retail space leases (leases for which there was a prior tenant), at an average rental rate increase on a cash and GAAP basis of 1.9% and 22.3%, respectively. New retail leases for comparable spaces were signed for 4,783 square feet at an average rental rate increase on a cash and GAAP basis of 36.4% and 0%, respectively. Renewals for comparable retail spaces were signed for 98,528 square feet at an average rental rate increase on a cash and GAAP basis of 0.7% and 15.7%, respectively. Tenant improvements and incentives were $41.14 per square foot of retail space for comparable new leases for the three months ended March 31, 2024, mainly due to new tenants at Del Monte Center and Solana Beach Towne Centre.

The rental increases associated with comparable spaces generally include all leases signed in arms-length transactions reflecting market leverage between landlords and tenants during the period. The comparison between average rent for expiring leases and new leases is determined by including minimum rent paid on the expiring lease and minimum rent to be paid on the new lease. In some instances, management exercises judgment as to how to most effectively reflect the comparability of spaces reported in this calculation. The change in rental income on comparable space leases is impacted by numerous factors including current market rates, location, individual tenant creditworthiness, use of space, market conditions when the expiring lease was signed, capital investment made in the space and the specific lease structure. Tenant improvements and incentives include the total dollars committed for the improvement of a space as it relates to a specific lease, but may also include base-building costs (i.e. expansion, escalators or new entrances) which are required to make the space leasable. Incentives include amounts paid to tenants as an inducement to sign a lease that do not represent building improvements.

The leases signed in 2024 generally become effective over the following year, though some may not become effective until 2025 and beyond. Further, there is risk that some new tenants will not ultimately take possession of their space and that tenants for both new and renewal leases may not pay all of their contractual rent due to operating, financing or other matters.

Capitalized Costs

Certain external and internal costs directly related to the development and redevelopment of real estate, including pre-construction costs, real estate taxes, insurance, interest, construction costs and salaries and related costs of personnel directly involved, are capitalized. We capitalize costs under development until construction is substantially complete and the property is held available for occupancy. The determination of when a development project is substantially complete and when capitalization must cease involves a degree of judgment. We consider a construction project as substantially complete and held available for occupancy upon the completion of landlord-owned tenant improvements or when the lessee takes possession of the unimproved space for construction of its own improvements, but not later than one year from cessation of major construction activity. We cease capitalization on the portion substantially completed and occupied or held available for occupancy, and capitalize only those costs associated with any remaining portion under construction.

We capitalized external and internal costs related to both development and redevelopment activities combined of $3.5 million and $9.6 million for the three months ended March 31, 2024 and 2023, respectively.

32

We capitalized external and internal costs related to other property improvements combined of $9.6 million and $12.4 million for the three months ended March 31, 2024 and 2023, respectively.

Interest costs on developments and major redevelopments are capitalized as part of developments and redevelopments not yet placed in service. Capitalization of interest commences when development activities and expenditures begin and end upon completion, which is when the asset is ready for its intended use as noted above. We make judgments as to the time period over which to capitalize such costs and these assumptions have a direct impact on net income because capitalized costs are not subtracted in calculating net income. If the time period for capitalizing interest is extended, however, more interest is capitalized, thereby decreasing interest expense and increasing net income during that period. We capitalized interest costs related to development activities of $2.1 million and $1.8 million for the three months ended March 31, 2024 and 2023, respectively.

Results of Operations

For our discussion of results of operations, we have provided information on a total portfolio and same-store basis.

Comparison of the three months ended March 31, 2024 to the three months ended March 31, 2023

The following summarizes our consolidated results of operations for the three months ended March 31, 2024 compared to our consolidated results of operations for the three months ended March 31, 2023. As of March 31, 2024 and March 31, 2023, our operating portfolio was comprised of 31 retail, office, multifamily and mixed-use properties with an aggregate of approximately 7.2 million rentable square feet of retail and office space, including the retail portion of our mixed-use property, 2,110 residential units (including 120 RV spaces) and a 369-room hotel. Additionally, as of March 31, 2024 and March 31, 2023, we owned land at three of our properties that we classified as held for development and/or construction in progress.

Revenue

Total property revenues. Total property revenue consists of rental revenue and other property income. Total property revenue increased $2.9 million to $110.7 million for the three months ended March 31, 2024 compared to $107.8 million for the three months ended March 31, 2023. The percentage leased was as follows for each segment as of March 31, 2024 and 2023:

	Percentage Leased(1)
	March 31,
	2024		2023
Office	86.4	%	88.1	%
Retail	94.4	%	93.8	%
Multifamily	92.8	%	91.8	%
Mixed-Use (2)	95.4	%	95.0	%

(1)The percentage leased for our retail and office segments and the retail portion of the mixed-use segment includes square footage under leases, including leases which may not have commenced as of March 31, 2024 or 2023, as applicable. Percentage leased for our multifamily properties includes total units rented and occupied as of March 31, 2024 or 2023, as applicable.

(2)Includes the retail portion of the mixed-use property only.

34

Total office rental revenue increased $0.3 million for the three months ended March 31, 2024 compared to the three months ended March 31, 2023 primarily due to higher annualized base rents at Torrey Reserve, Solana Crossing, Torrey Point and La Jolla Commons attributable to new leases and scheduled rent increases.

Total retail rental revenue increased $0.5 million for the three months ended March 31, 2024 compared to the three months ended March 31, 2023 primarily due to new tenant leases and scheduled rent increases.

Total office property operating income increased $0.5 million for the three months ended March 31, 2024 compared to the three months ended March 31, 2023, primarily due to higher annualized base rents at Torrey Reserve, Solana Crossing, Torrey Point and La Jolla Commons. Additionally, there was an increase in other property income related to lease settlement fees received at Torrey Reserve and lower real estate taxes at City Center Bellevue and First & Main. These increases were offset by higher rental expenses related to utilities expense, janitorial expense, security services and insurance expense.

Total retail property operating income decreased $0.2 million for the three months ended March 31, 2024 compared to the three months ended March 31, 2023 primarily due to increased rental expenses attributable to higher insurance expense, and employee-related costs, and $0.5 million written off in the first quarter for non-recurring costs incurred in prior periods relating to construction in progress for then-prospective construction at Waikele Center. These decreases were offset by higher rental revenue at Carmel Mountain Plaza, Waikele Center and Del Monte Center due to new tenant leases and scheduled rent increases.

Total multifamily property operating income increased $0.3 million for the three months ended March 31, 2024 compared to the three months ended March 31, 2023 primarily due to higher rental revenue due to an overall increase in average monthly base rent to $2,681 for the three months ended March 31, 2024 compared to $2,514 for the three months ended March 31, 2023. These increases were offset by higher rental expenses related to insurance expense and employee-related costs.

37

Total mixed-use property operating income increased $0.4 million for the three months ended March 31, 2024 compared to the three months ended March 31, 2023 primarily due to increase in tourism, which led to an increase in average occupancy and revenue per available room to 89.8% and $320, respectively, for the three months ended March 31, 2024, compared to 81.9% and $302, respectively, for the three months ended March 31, 2023. This also led to an increase in other room rental income at the hotel portion of our mixed-use property. These increases were offset by higher hotel room expenses and employee related costs at the hotel portion of our mixed-use property.

Other

General and Administrative. General and administrative expenses decreased $0.2 million, or 2%, for the three months ended March 31, 2024, compared to the three months ended March 31, 2023. This decrease was primarily due to lower general legal expense and stock-based compensation expense, attributable to a decrease in the number of restricted stock awards granted as part of our 2023 grant. These decreases were offset by higher employee-related costs, including, without limitation, with respect to base pay for certain salaried and hourly workers and benefits.

Depreciation and Amortization. Depreciation and amortization expense increased $0.3 million, or 1%, for the three months ended March 31, 2024, compared to the three months ended March 31, 2023. This was due to new building improvements and furniture and equipment assets placed into service in 2023.

Interest Expense, net. Interest expense increased $0.5 million, or 3%, for the three months ended March 31, 2024, compared to the three months ended March 31, 2023. This increase was primarily due to higher interest on our $225 million Amended and Restated Term Loan Agreement and related amortization of loan fees. These increases were offset by an increase in capitalized interest related to our development projects.

Other Income (Expense), Net. Other income, net increased $3.7 million, or 55%, for the three months ended March 31, 2024, compared to the three months ended March 31, 2023. This increase was primarily due to the net settlement payment of approximately $10 million received during the first quarter of 2024 relating to building specifications for one of the existing buildings at our office project in University Town Center (San Diego), compared to the net settlement payment of approximately $6.3 million received on January 3, 2023 related to certain building systems at our Hassalo on Eighth property.

Liquidity and Capital Resources of American Assets Trust, Inc.

In this “Liquidity and Capital Resources of American Assets Trust, Inc.” section, the term the “company” refers only to American Assets Trust, Inc. on an unconsolidated basis, and excludes the Operating Partnership and all other subsidiaries.

The company’s business is operated primarily through the Operating Partnership, of which the company is the parent company and sole general partner, and which it consolidates for financial reporting purposes.  Because the company operates on a consolidated basis with the Operating Partnership, the section entitled “Liquidity and Capital Resources of American Assets Trust, L.P.” should be read in conjunction with this section to understand the liquidity and capital resources of the company on a consolidated basis and how the company is operated as a whole.

The company issues public equity from time to time, but does not otherwise generate any capital itself or conduct any business itself, other than incurring certain expenses in operating as a public company which are fully reimbursed by the Operating Partnership. The company itself does not have any indebtedness, and its only material asset is its ownership of partnership interests of the Operating Partnership. Therefore, the consolidated assets and liabilities and the consolidated revenues and expenses of the company and the Operating Partnership are the same on their respective financial statements.  However, all debt is held directly or indirectly by the Operating Partnership. The company’s principal funding requirement is the payment of dividends on its common stock. The company’s principal source of funding for its dividend payments is distributions it receives from the Operating Partnership.

As of March 31, 2024, the company owned an approximate 78.8% partnership interest in the Operating Partnership. The remaining approximately 21.2% are owned by non-affiliated investors and certain of the company's directors and executive officers. As the sole general partner of the Operating Partnership, American Assets Trust, Inc. has the full, exclusive and complete authority and control over the Operating Partnership’s day-to-day management and business, can cause it to enter into certain major transactions, including acquisitions, dispositions and refinancings, and can cause changes in its line of business, capital structure and distribution policies. The company causes the Operating Partnership to distribute such portion of its available cash as the company may in its discretion determine, in the manner provided in the Operating Partnership’s partnership agreement.

38

The liquidity of the company is dependent on the Operating Partnership’s ability to make sufficient distributions to the company. The primary cash requirement of the company is its payment of dividends to its stockholders. The company also guarantees some of the Operating Partnership’s debt, as discussed further in Note 7 of the Notes to Consolidated Financial Statements included elsewhere herein. If the Operating Partnership fails to fulfill certain of its debt requirements, which trigger the company’s guarantee obligations, then the company will be required to fulfill its cash payment commitments under such guarantees. However, the company’s only significant asset is its investment in the Operating Partnership.

We believe the Operating Partnership’s sources of working capital, specifically its cash flow from operations, and borrowings available under its unsecured line of credit, are adequate for it to make its distribution payments to the company and, in turn, for the company to make its dividend payments to its stockholders. As of March 31, 2024, the company has determined that it has adequate working capital to meet its dividend funding obligations for the next 12 months. However, we cannot assure you that the Operating Partnership’s sources of capital will continue to be available at all or in amounts sufficient to meet its needs, including its ability to make distribution payments to the company. The unavailability of capital could adversely affect the Operating Partnership’s ability to pay its distributions to the company, which would in turn, adversely affect the company’s ability to pay cash dividends to its stockholders.

Our short-term liquidity requirements consist primarily of funds to pay for future dividends expected to be paid to the company’s stockholders, operating expenses and other expenditures directly associated with our properties, interest expense and scheduled principal payments on outstanding indebtedness, general and administrative expenses, funding construction projects, capital expenditures, tenant improvements and leasing commissions.

The company may from time to time seek to repurchase or redeem the Operating Partnership’s outstanding debt, the company’s shares of common stock or other securities in open market purchases, privately negotiated transactions or otherwise. Such repurchases or redemptions, if any, will depend on prevailing market conditions, our liquidity requirements, contractual restrictions and other factors. The amounts involved may be material.

For the company to maintain its qualification as a REIT, it must pay dividends to its stockholders aggregating annually at least 90% of its REIT taxable income, excluding net capital gains. While historically the company has satisfied this distribution requirement by making cash distributions to American Assets Trust, Inc.'s stockholders or American Assets Trust, L.P.'s unitholders, it may choose to satisfy this requirement by making distributions of cash or other property, including, in limited circumstances, the company’s own stock. As a result of this distribution requirement, the Operating Partnership cannot rely on retained earnings to fund its ongoing operations to the same extent that other companies whose parent companies are not REITs can. The company may need to continue to raise capital in the equity markets to fund the operating partnership’s working capital needs, acquisitions and developments. Although there is no intent at this time, if market conditions deteriorate, the company may also delay the timing of future development and redevelopment projects as well as limit future acquisitions, reduce the Operating Partnership’s operating expenditures, or re-evaluate its dividend policy.

The company is a well-known seasoned issuer. As circumstances warrant, the company may issue equity from time to time on an opportunistic basis, dependent upon market conditions and available pricing. When the company receives proceeds from preferred or common equity issuances, it is required by the Operating Partnership’s partnership agreement to contribute the proceeds from its equity issuances to the Operating Partnership in exchange for partnership units of the Operating Partnership. The Operating Partnership may use the proceeds to repay debt, to develop new or existing properties, to acquire properties or for general corporate purposes.

In December 2023, the company, together with the Operating Partnership, filed a universal shelf registration statement on Form S-3ASR with the SEC, which became effective upon filing and which replaced the prior Form S-3ASR that was filed with the SEC in January 2021. The universal shelf registration statement may permit the company from time to time to offer and sell equity securities of the company.  However, there can be no assurance that the company will be able to complete any such offerings of securities.  Factors influencing the availability of additional financing include investor perception of our prospects and the general condition of the financial markets, among others.

On December 3, 2021, we entered into a new ATM equity program with five sales agents under which we may, from time to time, offer and sell shares of our common stock having an aggregate offering price of up to $250.0 million. The sale of shares of our common stock made through the ATM equity program are made in "at-the-market" offerings as defined in Rule 415 of the Securities Act of 1933, as amended.

We intend to use the net proceeds to fund development or redevelopment activities, repay amounts outstanding from time to time under our amended and restated credit facility or other debt financing obligations, fund potential acquisition opportunities and/or for general corporate purposes. Actual future sales will depend on a variety of factors including, but not

39

limited to, market conditions, the trading price of the company's common stock and the company's capital needs. For the three months ended March 31, 2024, no shares of common stock were sold through the ATM equity program. We have no obligation to sell the remaining shares available for sale under the ATM equity program.

Liquidity and Capital Resources of American Assets Trust, L.P.

In this “Liquidity and Capital Resources of American Assets Trust, L.P.” section, the terms “we,” “our” and “us” refer to the Operating Partnership together with its consolidated subsidiaries, or the Operating Partnership and American Assets Trust, Inc. together with their consolidated subsidiaries, as the context requires. American Assets Trust, Inc. is our sole general partner and consolidates our results of operations for financial reporting purposes. Because we operate on a consolidated basis with American Assets Trust, Inc., the section entitled “Liquidity and Capital Resources of American Assets Trust, Inc.” should be read in conjunction with this section to understand our liquidity and capital resources on a consolidated basis.

Due to the nature of our business, we typically generate significant amounts of cash from operations. The cash generated from operations is used for the payment of operating expenses, capital expenditures, debt service and dividends to American Assets Trust, Inc.'s stockholders and our unitholders. As a REIT, American Assets Trust, Inc. must generally make annual distributions to its stockholders of at least 90% of its net taxable income. As of March 31, 2024, we held $98.6 million in cash and cash equivalents.

Our short-term liquidity requirements consist primarily of operating expenses and other expenditures associated with our properties, regular debt service requirements, dividend payments to American Assets Trust, Inc.'s stockholders required to maintain its REIT status, distributions to our unitholders, capital expenditures and, potentially, acquisitions. We expect to meet our short-term liquidity requirements through net cash provided by operations, reserves established from existing cash and, if necessary, borrowings available under our credit facility.

Our long-term liquidity needs consist primarily of funds necessary to pay for the repayment of debt at maturity, property acquisitions, tenant improvements and capital improvements. We expect to meet our long-term liquidity requirements to pay scheduled debt maturities and to fund property acquisitions and capital improvements with net cash from operations, long-term secured and unsecured indebtedness and, if necessary, the issuance of equity and debt securities. We also may fund property acquisitions and capital improvements using our amended and restated credit facility pending permanent financing. We believe that we have access to multiple sources of capital to fund our long-term liquidity requirements, including the incurrence of additional debt and the issuance of additional equity. However, we cannot be assured that this will be the case. Our ability to incur additional debt will be dependent on a number of factors, including our degree of leverage, the value of our unencumbered assets and borrowing restrictions that may be imposed by lenders. Our ability to access the equity capital markets will be dependent on a number of factors as well, including general market conditions for REITs and market perceptions about our company.

Our overall capital requirements for the remainder of 2024 and for the three months ending March 31, 2025 will depend upon acquisition opportunities and the level of improvements and redevelopments on existing properties. Our capital investments will be funded on a short-term basis with, among other sources of capital, cash on hand, cash flow from operations and/or our revolving line of credit. On a long-term basis, our capital investments may be funded with additional long-term debt, including, without limitation, mortgage debt and unsecured notes. Our ability to incur additional debt will be dependent on a number of factors, including, without limitation, our degree of leverage, the value of our unencumbered assets and borrowing restrictions that may be imposed by lenders. Our capital investments may also be funded by issuing additional equity including, without limitation, shares issued by American Assets Trust, Inc. under its ATM equity program or through an underwritten public offering. Although there is no intent at this time, if market conditions deteriorate or fail to improve, we may also delay the timing of future development and redevelopment projects as well as limit future acquisitions, reduce our operating expenditures, or re-evaluate our dividend policy.

In December 2023, the Operating Partnership, together with American Assets Trust, Inc., filed a universal shelf registration statement on Form S-3ASR with the SEC, which became effective upon filing and which replaced the prior Form S-3ASR that was filed with the SEC in January 2021. The universal shelf registration statement may permit the company from time to time to offer and sell equity securities of the company.  However, there can be no assurance that the company will be able to complete any such offerings of securities.  Factors influencing the availability of additional financing include investor perception of our prospects and the general condition of the financial markets, among others.

Cash Flows

Comparison of the three months ended March 31, 2024 to the three months ended March 31, 2023

Cash, cash equivalents, and restricted cash were $98.6 million and $87.3 million at March 31, 2024 and 2023, respectively.

Net cash provided by operating activities increased $2.8 million to $54.8 million for the three months ended March 31, 2024 compared to $52.0 million for the three months ended March 31, 2023. The increase in cash from operations was primarily due to the net settlement received relating to building specifications for one of the existing buildings at our office project in University Town Center (San Diego), increase in rental revenue and changes in operating assets and liabilities.

Net cash used in investing activities decreased $12.4 million to $13.3 million for the three months ended March 31, 2024 compared to $25.7 million for the three months ended March 31, 2023. The decrease in cash used was primarily due to the decrease in capital expenditures at La Jolla Commons III and One Beach Street as these projects have completed construction.

Net cash used by financing activities increased $37.3 million to $25.8 million for the three months ended March 31, 2024 compared to cash provided by financing activities of $11.5 million for the three months ended March 31, 2023. The increase in cash used in financing activities was primarily due to the term loan agreement that was amended and restated in 2023, among other things, to increase the fully drawn borrowings from $150 million to $225 million. This was partially offset by the repayment of the outstanding balance on the revolving line of credit.

Net Operating Income

Net Operating Income, or NOI, is a non-GAAP financial measure of performance. We define NOI as operating revenues (rental income, tenant reimbursements, lease termination fees, ground lease rental income and other property income) less property and related expenses (property expenses, ground lease expense, property marketing costs, real estate taxes and insurance). NOI excludes general and administrative expenses, interest expense, depreciation and amortization, acquisition-related expense, other non-property income and losses, gains and losses from property dispositions, extraordinary items, tenant improvements, and leasing commissions. Other REITs may use different methodologies for calculating NOI, and accordingly, our NOI may not be comparable to the NOIs of other REITs.

NOI is used by investors and our management to evaluate and compare the performance of our properties and to determine trends in earnings and to compute the fair value of our properties as it is not affected by (1) the cost of funds of the property owner, (2) the impact of depreciation and amortization expenses as well as gains or losses from the sale of operating real estate assets that are included in net income computed in accordance with GAAP or (3) general and administrative expenses and other gains and losses that are specific to the property owner. The cost of funds is eliminated from net income because it is specific to the particular financing capabilities and constraints of the owner. The cost of funds is also eliminated because it is dependent on historical interest rates and other costs of capital as well as past decisions made by us regarding the appropriate mix of capital, which may have changed or may change in the future. Depreciation and amortization expenses as well as gains or losses from the sale of operating real estate assets are eliminated because they may not accurately represent the actual change in value in our retail, office, multifamily or mixed-use properties that result from use of the properties or changes in market conditions. While certain aspects of real property do decline in value over time in a manner that is intended to be captured by depreciation and amortization, the value of the properties as a whole have historically increased or decreased as a result of changes in overall economic conditions instead of from actual use of the property or the passage of time. Gains and losses from the sale of real property vary from property to property and are affected by market conditions at the time of sale, which will usually change from period to period. These gains and losses can create distortions when comparing one period to another or when comparing our operating results to the operating results of other real estate companies that have not made similarly timed purchases or sales. We believe that eliminating these costs from net income is useful because the resulting measure captures the actual revenue generated and actual expenses incurred in operating our properties as well as trends in occupancy rates, rental rates and operating costs.

However, the usefulness of NOI is limited because it excludes general and administrative costs, interest expense, interest income and other expense, depreciation and amortization expense and gains or losses from the sale of properties, and other gains and losses as stipulated by GAAP, the level of capital expenditures and leasing costs necessary to maintain the operating performance of our properties, all of which are significant economic costs. NOI may fail to capture significant trends in these components of net income, which further limits its usefulness.

NOI is a measure of the operating performance of our properties but does not measure our performance as a whole. NOI is therefore not a substitute for net income as computed in accordance with GAAP. This measure should be analyzed in conjunction with net income computed in accordance with GAAP and discussions elsewhere in “Management's Discussion and

41

Analysis of Financial Condition and Results of Operations” regarding the components of net income that are eliminated in the calculation of NOI. Other companies may use different methods for calculating NOI or similarly entitled measures and, accordingly, our NOI may not be comparable to similarly entitled measures reported by other companies that do not define the measure exactly as we do.  

The following is a reconciliation of our NOI to net income for the three months ended March 31, 2024 and 2023 computed in accordance with GAAP (in thousands):

 

	Three Months Ended March 31,
	2024		2023
Net operating income	$	69,608	$	68,616
General and administrative	(8,842)		(8,999)
Depreciation and amortization	(30,217)		(29,901)
Interest expense, net	(16,255)		(15,729)
Other income (expense), net	10,329		6,679
Net income	$	24,623	$	20,666

Funds from Operations

We calculate funds from operations ("FFO"), in accordance with the standards established by the National Association of Real Estate Investment Trusts ("NAREIT"). FFO represents net income (computed in accordance with GAAP), excluding gains (or losses) from sales of depreciable operating property, impairment losses, real-estate related depreciation and amortization (excluding amortization of deferred financing costs) and after adjustments for unconsolidated partnerships and joint ventures.

FFO is a supplemental non-GAAP financial measure. Management uses FFO as a supplemental performance measure because it believes that FFO is beneficial to investors as a starting point in measuring our operational performance. Specifically, in excluding real-estate related depreciation and amortization and gains and losses from property dispositions, which do not relate to or are not indicative of operating performance, FFO provides a performance measure that, when compared year over year, captures trends in occupancy rates, rental rates and operating costs. We also believe that, as a widely recognized measure of the performance of REITs, FFO will be used by investors as a basis to compare our operating performance with that of other REITs. However, because FFO excludes depreciation and amortization and captures neither the changes in the value of our properties that result from use or market conditions nor the level of capital expenditures and leasing commissions necessary to maintain the operating performance of our properties, all of which have real economic effects and could materially impact our results from operations, the utility of FFO as a measure of our performance is limited. In addition, other equity REITs may not calculate FFO in accordance with the NAREIT definition as we do, and, accordingly, our FFO may not be comparable to such other REITs' FFO. Accordingly, FFO should be considered only as a supplement to net income as a measure of our performance. FFO should not be used as a measure of our liquidity, nor is it indicative of funds available to fund our cash needs, including our ability to pay dividends or service indebtedness. FFO also should not be used as a supplement to or substitute for cash flow from operating activities computed in accordance with GAAP.

The following table sets forth a reconciliation of our net income for the three months ended March 31, 2024 to FFO, the nearest GAAP equivalent (in thousands, except per share and share data): 

	Three Months Ended March 31,
	2024
Funds from Operations (FFO)
Net income	$	24,623
Plus: Real estate depreciation and amortization	30,217
Funds from operations	54,840
Less: Nonforfeitable dividends on incentive restricted stock awards	(192)
FFO attributable to common stock and units	$	54,648
FFO per diluted share/unit	$	0.71
Weighted average number of common shares and units, diluted (1)	76,500,185

42

(1)The weighted average common shares used to compute FFO per diluted share include unvested restricted stock awards that are subject to time vesting, which were excluded from the computation of diluted EPS, as the vesting of the restricted stock awards is dilutive in the computation of FFO per diluted share but is anti-dilutive for the computation of diluted EPS for the period. Diluted shares exclude incentive restricted stock as these awards are considered contingently issuable.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Our future income, cash flows and fair values relevant to financial instruments are dependent upon prevalent market interest rates. Market risk refers to the risk of loss from adverse changes in market prices and interest rates. We manage our market risk by attempting to match anticipated inflow of cash from our operating, investing and financing activities with anticipated outflow of cash to fund debt payments, dividends to our stockholders and Operating Partnership unitholders, investments, capital expenditures and other cash requirements.

Interest Rate Risk

Outstanding Debt

The following discusses the effect of hypothetical changes in market rates of interest on the fair value of our total outstanding debt. Interest rate risk amounts were determined by considering the impact of hypothetical interest rates on our debt. Discounted cash flow analysis is generally used to estimate the fair value of our mortgages payable. Considerable judgment is necessary to estimate the fair value of financial instruments. This analysis does not purport to take into account all of the factors that may affect our debt, such as the effect that a changing interest rate environment could have on the overall level of economic activity or the action that our management might take to reduce our exposure to the change. This analysis assumes no change in our financial structure.

Fixed Interest Rate Debt

Our outstanding notes payable obligations (maturing at various times through February 2031) have fixed interest rates which limit the risk of fluctuating interest rates. However, interest rate fluctuations may affect the fair value of our fixed rate debt instruments. At March 31, 2024, we had $1.4 billion of fixed rate debt outstanding with an estimated fair value of $1.2 billion. The carrying values of our revolving line of credit and term loans are deemed to be at fair value since the outstanding debt is directly tied to monthly SOFR contracts. If interest rates at March 31, 2024 had been 1.0% higher, the fair value of those debt instruments on that date would have decreased by approximately $38.0 million. If interest rates at March 31, 2024 had been 1.0% lower, the fair value of those debt instruments on that date would have increased by approximately $51.3 million. Additionally, we consider $325.0 million related to Term Loan A, Term Loan B and Term Loan C outstanding as of March 31, 2024 to be fixed rate debt as the rate is effectively fixed by interest rate swap agreements.

Variable Interest Rate Debt

At March 31, 2024, we had $325.0 million of variable rate debt outstanding, all of which is subject to interest rate swaps as described above. We have historically entered into forward starting interest rate swaps in order to economically hedge against the risk of rising interest rates that would affect our interest expense related to our future anticipated debt issuances as part of its overall borrowing program. See the discussion under Note 4 to the accompanying consolidated financial statements for certain quantitative details related to the interest rate swaps and for a discussion on how we value derivative financial instruments.  Based upon this amount of variable rate debt and the specific terms, if market interest rates increased or decreased by 1.0%, our annual interest expense would not change and have no corresponding change in our net income and cash flows for the year, since this variable rate debt is effectively fixed by interest rate swap agreements.

ITEM 4. CONTROLS AND PROCEDURES

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”) and 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.

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, 2023.

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, number of units, 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, 2023. There have been no changes to our significant accounting policies during the three months ended March 31, 2024.

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 office real estate, retail real estate, multifamily real estate and mixed-use real estate. 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 retail segment primarily include rental of retail 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

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.

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 March 31, 2024 and December 31, 2023 was approximately $1.4 million and $1.4 million, respectively.

Recent Accounting Pronouncements

In November 2023, the FASB issued Accounting Standards Update (“ASU”) 2023-07, Improvements to Reportable Segment Disclosures. The pronouncement requires disclosure of significant segment expenses that are regularly provided to the chief operating decision maker and included within the segment measure of profit or loss. The pronouncement will be applied retrospectively and is effective for annual reporting periods in fiscal years beginning after December 15, 2023, and interim reporting periods in fiscal years beginning after December 31, 2024. We are currently evaluating the impact this pronouncement will have on our disclosures.

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.

FAIR VALUE OF FINANCIAL INSTRUMENTS

Fair Value Disclosures [Abstract]

FAIR VALUE OF FINANCIAL INSTRUMENTS

FAIR VALUE OF FINANCIAL INSTRUMENTS

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, restricted cash, 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 March 31, 2024 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.

A summary of our financial liabilities that are measured at fair value on a recurring basis, by level within the fair value hierarchy is as follows (in thousands):

	March 31, 2024								December 31, 2023
	Level 1		Level 2		Level 3		Total		Level 1		Level 2		Level 3		Total
Deferred compensation liability	$	—	$	2,622	$	—	$	2,622	$	—	$	2,627	$	—	$	2,627

Interest rate swap liability	$	—	$	—	$	—	$	—	$	—	$	—	$	—	$	—

 The fair value of our secured notes payable and unsecured senior guaranteed notes are sensitive to fluctuations in interest rates. Discounted cash flow analysis using observable market interest rates (Level 2) is generally used to estimate the fair value of our secured notes payable, using rates ranging from 5.7% to 6.5%.

Considerable judgment is necessary to estimate the fair value of financial instruments. The estimates of fair value presented herein are not necessarily indicative of the amounts that could be realized upon disposition of the financial instruments. The carrying values of our term loans set forth below are deemed to be at fair value since the outstanding debt is directly tied to monthly SOFR. A summary of the carrying amount and fair value of our secured financial instruments, all of which are based on Level 2 inputs, is as follows (in thousands):

DERIVATIVE AND HEDGING ACTIVITIES

Derivative Instruments and Hedging Activities Disclosure [Abstract]

DERIVATIVE AND HEDGING ACTIVITIES

DERIVATIVE AND HEDGING ACTIVITIES

Our objectives in using interest rate derivatives are to add stability to interest expense and to manage our exposure to interest rate movements.  To accomplish these objectives, we primarily use interest rate swaps as part of our interest rate risk management strategy.  Interest rate swaps designated as cash flow hedges involve the receipt of variable-rate amounts from a counterparty in exchange for us making fixed-rate payments over the life of the agreements without exchange of the underlying notional amount. 

The following is a summary of the terms of our outstanding interest rate swaps as of March 31, 2024 (dollars in thousands):

Swap Counterparty	Notional Amount		Effective Date	Maturity Date	Fair Value
Bank of America, N.A.	$	50,000	1/14/2022	1/5/2027	$	3,738
Wells Fargo Bank, N.A.	$	50,000	1/14/2022	1/5/2027	$	3,899
Wells Fargo Bank, N.A.	$	150,000	1/5/2023	1/5/2025	$	1,352
Mizuho Capital Markets LLC	$	75,000	1/5/2023	1/5/2025	$	366

The effective portion of changes in the fair value of the derivatives that are designated as cash flow hedges are being recorded in accumulated other comprehensive income and will be subsequently reclassified into earnings during the period in which the hedged forecasted transaction affects earnings for as long as hedged cash flows remain probable. During the next twelve months, we estimate the cash flow hedges in place will reduce interest expense by approximately $0.4 million.

The valuation of these instruments is determined using widely accepted valuation techniques including discounted cash flow analysis on the expected cash flows of the derivative.  This analysis reflects the contractual terms of the derivative, including the period to maturity, and counterparty credit risk and uses observable market-based inputs, including interest rate curves, and implied volatilities.  The fair value of the interest rate swap is determined using the market standard methodology of netting the discounted future fixed cash receipts (or payments) and the discounted expected variable cash payments (or receipts).  The variable cash payments (or receipts) are based on an expectation of future interest rates (forward curves) derived from observable market interest rate curves.

On July 30, 2019, the Operating Partnership entered into a Note Purchase Agreement for the private placement of $150 million of 3.91% Senior Guaranteed Notes, Series G, due July 30, 2030 (the "Series G Notes" and collectively with the Series A Notes, Series B Notes, Series C Notes, Series D Notes, Series E Notes, and Series G Notes are referred to herein as, the “Notes".) The Series G Notes were issued on July 30, 2019 and pay interest semi-annually on the 30th of July and January until their maturity.

The Operating Partnership may prepay at any time all, or from time to time any part of, the Notes, in an amount not less than 5% of the aggregate principal amount of any series of the Notes then outstanding in the case of a partial prepayment, at 100% of the principal amount so prepaid plus a make-whole amount.

The Note Purchase Agreements contain a number of customary financial covenants, including, without limitation, tangible net worth thresholds, secured and unsecured leverage ratios and fixed charge coverage ratios. Subject to the terms of the Note Purchase Agreement and the Notes, upon certain events of default, including, but not limited to, (i) a default in the payment of any principal, Make-Whole Amount or interest under the Notes, and (ii) a default in the payment of certain other indebtedness by us or our subsidiaries, the principal, accrued and unpaid interest, and the make-whole amount on the outstanding Notes will become due and payable at the option of the purchasers.

The Operating Partnership's obligations under the Notes are fully and unconditionally guaranteed by the Operating Partnership and certain of the Operating Partnership's subsidiaries.

Certain loans require the Operating Partnership to comply with various financial covenants, including the maintenance of minimum debt coverage ratios. As of March 31, 2024, the Operating Partnership was in compliance with all loan covenants.

On January 5, 2022, the Operating Partnership entered into the third amended and restated credit facility (the “Third Amended and Restated Credit Facility”) , which amended and restated our then-existing credit facility. The Third Amended and Restated Credit Facility provides for aggregate, unsecured borrowings of up to $500 million, consisting of a revolving line of credit of $400 million (the “Revolver Loan”) and a term loan of $100 million (“Term Loan A”). The Revolver Loan initially matures on January 5, 2026, subject to two, six-month extension options. Term Loan A matures on January 5, 2027, with no further extension options. As of March 31, 2024, the entirety of the principal amount of Term Loan A was outstanding, there were no amounts outstanding under the Revolver Loan, and the Operating Partnership had incurred approximately $1.13 million of net debt issuance costs which are recorded in other assets, net on the consolidated balance sheet. For the three months ended March 31, 2024, the weighted average interest rate on the Revolver Loan was 6.54%.

Borrowings under the Third Amended and Restated Credit Agreement bear interest at floating rates equal to, at the Operating Partnership’s option, either (1) the applicable SOFR, plus the applicable SOFR Adjustment and a spread which ranges from (a) 1.05%-1.50% (with respect to the Revolver Loan) and (b) 1.20% to 1.70% (with respect to Term Loan A), in each case based on our consolidated leverage ratio, or (2) a base rate equal to the highest of (a) the prime rate, (b) the federal funds rate plus 50 bps, (c) the Term SOFR Screen Rate with a term of one month plus 100 bps and (d) 1.00%, plus a spread which ranges from (i) 0.10%-0.50% (with respect to the Revolver Loan) and (ii) 0.20% to 0.70% (with respect to Term Loan A), in each case based on our consolidated leverage ratio. On January 14, 2022, the Operating Partnership entered into an interest rate swap agreement intended to fix the interest rate associated with the Term Loan A at approximately 2.70% through January 5, 2027, subject to adjustments based on our consolidated leverage ratio.

The Third Amended and Restated Credit Facility includes a number of customary financial covenants, including:

•A maximum leverage ratio (defined as total indebtedness net of certain cash and cash equivalents to total asset

value) of 60%,

•A maximum secured leverage ratio (defined as total secured debt to secured total asset value) of 40%,

•A minimum fixed charge coverage ratio (defined as consolidated earnings before interest, taxes, depreciation and

amortization to consolidated fixed charges) of 1.50x,

•A minimum unsecured interest coverage ratio of 1.75x,

•A maximum unsecured leverage ratio of 60%, and

•Recourse indebtedness at any time cannot exceed 15% of total asset value.

The Third Amended and Restated Credit Facility also provides that our annual distributions may not exceed the greater of (1) 95% of our funds from operations (“FFO”) or (2) the amount required for us to (a) qualify and maintain our REIT status and (b) avoid the payment of federal or state income or excise tax. If certain events of default exist or would result from a distribution, we may be precluded from making distributions other than those necessary to qualify and maintain our status as a REIT.

As of March 31, 2024, the Operating Partnership was in compliance with all then in-place Third Amended and Restated Credit Facility covenants.

Amended and Restated Term Loan Agreement

On January 5, 2023, we entered into the amended and restated term loan agreement (the “Amended and Restated Term Loan Agreement”), which amended and restated our then-existing term loan agreement. The Amended and Restated Term Loan Agreement provides to the Operating Partnership a term loan of $150 million (“Term Loan B”) and a term loan of $75 million (“Term Loan C”), each maturing on January 5, 2025, with one, twelve-month extension option, subject to certain conditions. As of March 31, 2024, the entirety of the principal amounts of Term Loan B and Term Loan C were outstanding.

Borrowings under the Amended and Restated Term Loan Agreement bear interest at floating rates equal to, at the Operating Partnership’s option, either (1) the applicable SOFR, plus a SOFR adjustment and a spread (based on the Operating Partnership’s consolidated leverage ratio and applicable year of Term Loan B and Term Loan C) ranging from 1.20% to 1.90%, or (2) a base rate equal to the highest of (a) 0%, (b) the prime rate, (c) the federal funds rate plus 50 bps and (d) the one-month SOFR, plus a SOFR adjustment and 100 bps, plus, in each case, a spread (based on the Operating Partnership’s consolidated

leverage ratio and applicable year of Term Loan B and Term Loan C) ranging from 0.20% to 0.90%. Additionally, the Operating Partnership may elect for borrowings to bear interest based on a ratings-based pricing grid based on the Operating Partnership’s then-applicable investment grade debt ratings under the terms set forth in the Amended and Restated Term Loan Agreement. Prior to entering into the Amended and Restated Term Loan Agreement, the Operating Partnership entered into interest rate swap agreements that are intended to fix the interest rate associated with Term Loan B and Term Loan C at approximately (1) 5.47% for the first year of Term Loan B and Term Loan C and (2) 5.57% for the second year of Term Loan B and Term Loan C, subject to adjustments based on the company’s consolidated leverage ratio.

The Amended and Restated Term Loan Agreement contains a number of customary financial covenants, including, without limitation, tangible net worth thresholds, secured and unsecured leverage ratios and fixed charge coverage ratios. Subject to the terms of the Amended and Restated Term Loan Agreement, upon certain events of default, including, but not limited to, (i) a default in the payment of any principal or interest under Term Loan B or Term Loan C, and (ii) a default in the payment of certain other indebtedness of the Operating Partnership, the company or their subsidiaries, the principal and accrued and unpaid interest and prepayment penalties on the outstanding Term Loan B or Term Loan C will become due and payable at the option of the lenders.

Equity [Abstract]

PARTNERS' CAPITAL OF AMERICAN ASSETS TRUST, L.P.

PARTNERS' CAPITAL OF AMERICAN ASSETS TRUST, L.P.

Noncontrolling interests in our Operating Partnership are interests in the Operating Partnership that are not owned by us. Noncontrolling interests consisted of 16,181,537 common units (the “noncontrolling common units”), and represented approximately 21.2% of the ownership interests in our Operating Partnership at March 31, 2024. Common units and shares of our common stock have essentially the same economic characteristics in that common units and shares of our common stock share equally in the total net income or loss distributions of our Operating Partnership. Investors who own common units have the right to cause our Operating Partnership to redeem any or all of their common units for cash equal to the then-current market value of one share of our common stock, or, at our election, shares of our common stock on a one-for-one basis.

During the three months ended March 31, 2024, no common units were converted into shares of our common stock.

Earnings Per Unit of the Operating Partnership

Basic earnings per unit (“EPU”) of the Operating Partnership is computed by dividing income applicable to unitholders by the weighted average Operating Partnership units outstanding, as adjusted for the effect of participating securities. Operating Partnership units granted in equity-based payment transactions that have non-forfeitable dividend equivalent rights are considered participating securities prior to vesting. The impact of unvested Operating Partnership unit awards on EPU has been calculated using the two-class method whereby earnings are allocated to the unvested Operating Partnership unit awards based on distributions and the unvested Operating Partnership units’ participation rights in undistributed earnings.

The calculation of diluted EPU for the three months ended March 31, 2024 and 2023 does not include the weighted average of 585,210 and 573,253 unvested outstanding Operating Partnership units, respectively, as these equity securities are either considered contingently issuable or the effect of including these equity securities was anti-dilutive to income from continuing operations and net income attributable to the unitholders.

EQUITY OF AMERICAN ASSETS TRUST, INC.

Stockholders' Equity

On December 3, 2021, we entered into an at-the-market ("ATM") equity program with five sales agents in which we may, from time to time, offer and sell shares of our common stock having an aggregate offering price of up to $250 million. The sales of shares of our common stock made through the ATM equity program, as amended, are made in "at-the-market" offerings as defined in Rule 415 of the Securities Act of 1933, as amended. For the three months ended March 31, 2024, no shares of common stock were sold through the ATM equity program.

We intend to use the net proceeds from the ATM equity program to fund our development or redevelopment activities, repay amounts outstanding from time to time under our revolving line of credit or other debt financing obligations, fund potential acquisition opportunities and/or for general corporate purposes. As of March 31, 2024, we had the capacity to issue up to $250 million in shares of our common stock under our current ATM equity program. Actual future sales will depend on a variety of factors including, but not limited to, market conditions, the trading price of our common stock and our capital needs. As of March 31, 2024, we have no obligation to sell the remaining shares available for sale under the ATM equity program.

Dividends

The following table lists the dividends declared and paid on our shares of common stock and noncontrolling common units during the three months ended March 31, 2024:

Period	Amount per Share/Unit		Period Covered	Dividend Paid Date
First Quarter 2024	$	0.335	January 1, 2024 to March 31, 2024	March 21, 2024

Taxability of Dividends

Earnings and profits, which determine the taxability of distributions to stockholders and holders of common units, may differ from income reported for financial reporting purposes due to the differences for federal income tax purposes in the treatment of revenue recognition and compensation expense and in the basis of depreciable assets and estimated useful lives used to compute depreciation.

Stock-Based Compensation

We follow the FASB guidance related to stock-based compensation which establishes financial accounting and reporting standards for stock-based employee compensation plans, including all arrangements by which employees receive shares of stock or other equity instruments of the employer.  The guidance also defines a fair value-based method of accounting for an employee stock award or similar equity instrument.

The following table summarizes the activity of restricted stock awards during the three months ended March 31, 2024:

	Units	Weighted Average Grant Date Fair Value
Nonvested at January 1, 2024	585,865	$	17.95
Granted	—	—
Vested	—	—
Forfeited	(1,295)	17.32
Nonvested at March 31, 2024	584,570	$	17.95

We recognize noncash compensation expense ratably over the vesting period, and accordingly, we recognized $1.6 million and $2.0 million in noncash compensation expense for the three months ended March 31, 2024 and 2023, respectively, which is included in general and administrative expenses on the consolidated statements of comprehensive income. Unrecognized compensation expense was $7.1 million at March 31, 2024.

Earnings Per Share

We have calculated earnings per share (“EPS”) under the two-class method. The two-class method is an earnings allocation methodology whereby EPS for each class of common stock and participating security is calculated according to dividends declared and participation rights in undistributed earnings. The weighted average unvested shares outstanding, which are considered participating securities, were 585,210 and 573,253 for the three months ended March 31, 2024 and 2023, respectively. Therefore, we have allocated our earnings for basic and diluted EPS between common shares and unvested shares as these unvested shares have nonforfeitable dividend equivalent rights.

Diluted EPS is calculated by dividing the net income applicable to common stockholders for the period by the weighted average number of common and dilutive instruments outstanding during the period using the treasury stock method. For the three months ended March 31, 2024 and 2023, diluted shares exclude incentive restricted stock as these awards are considered contingently issuable. Additionally, the unvested restricted stock awards subject to time vesting are anti-dilutive for all periods presented, and accordingly, have been excluded from the weighted average common shares used to compute diluted EPS.

The computation of basic and diluted EPS is presented below (dollars in thousands, except share and per share amounts):

Income Tax Disclosure [Abstract]

INCOME TAXES

INCOME TAXES

We elected to be taxed as a REIT and operate in a manner that allows us to qualify as a REIT for federal income tax purposes commencing with our initial taxable year. As a REIT, we are generally not subject to corporate level income tax on the earnings distributed currently to our stockholders that we derive from our REIT qualifying activities. Taxable income from non-REIT activities managed through our TRS is subject to federal and state income taxes.

We lease our hotel property to a wholly owned TRS that is subject to federal and state income taxes. We account for income taxes using the asset and liability method, under which deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between GAAP carrying amounts and their respective tax bases. Additionally, we classify certain state taxes as income taxes for financial reporting purposes in accordance with ASC Topic 740, Income Taxes.

A deferred tax asset is included in our consolidated balance sheets of $0.9 million and $0.9 million, and a deferred tax liability is included in our consolidated balance sheets of $0.8 million and $0.8 million as of March 31, 2024 and December 31,

2023, respectively, in relation to real estate asset basis differences of property subject to state taxes based on income and certain prepaid expenses of our TRS.

Income tax expense is recorded in other income, net on our consolidated statements of comprehensive income. For the three months ended March 31, 2024, we recorded income tax expense of $0.3 million. For the three months ended March 31, 2023, we recorded income tax expense of $0.3 million.

COMMITMENTS AND CONTINGENCIES

COMMITMENTS AND CONTINGENCIES

Legal

We are sometimes involved in various disputes, lawsuits, warranty claims, environmental considerations, and other matters arising in the ordinary course of business. Management makes assumptions and estimates concerning the likelihood and amount of any potential loss relating to these matters.

We are currently a party to various legal proceedings. We accrue a liability for litigation if an unfavorable outcome is probable and the amount of loss can be reasonably estimated. If an unfavorable outcome is probable and a reasonable estimate of the loss is a range, we accrue the best estimate within the range; however, if no amount within the range is a better estimate than any other amount, the minimum amount within the range is accrued. Legal fees related to litigation are expensed as incurred. We do not believe that the ultimate outcome of these matters, either individually or in the aggregate, could have a material adverse effect on our financial position or overall trends in results of operations; however, litigation is subject to inherent uncertainties. Also, under our leases, tenants are typically obligated to indemnify us from and against all liabilities, costs and expenses imposed upon or asserted against us as owner of the properties due to certain matters relating to the operation of the properties by the tenant.

Commitments

See Footnote 12 for description of our leases, as a lessee.

We have management agreements with Outrigger Hotels & Resorts or an affiliate thereof (“Outrigger”) pursuant to which Outrigger manages each of the retail and hotel portions of the Waikiki Beach Walk property. Under the management agreement with Outrigger relating to the retail portion of Waikiki Beach Walk (the “retail management agreement”), we pay Outrigger a monthly management fee of 3.0% of net revenues from the retail portion of Waikiki Beach Walk. Pursuant to the terms of the retail management agreement, if the agreement is terminated in certain instances, including our election not to repair damage or destruction at the property, a condemnation or our failure to make required working capital infusions, we would be obligated to pay Outrigger a termination fee equal to the sum of the management fees paid for the two months immediately preceding the termination date. The retail management agreement may not be terminated by us or by Outrigger without cause. Under our management agreement with Outrigger relating to the hotel portion of Waikiki Beach Walk (the “hotel management agreement”), we pay Outrigger a monthly management fee of 6.0% of the hotel's gross operating profit, as well as 3.0% of the hotel's gross revenues; provided that the aggregate management fee payable to Outrigger for any year shall not exceed 3.5% of the hotel's gross revenues for such fiscal year. The hotel management agreement may not be terminated by us or by Outrigger without cause. Additionally, we have a management agreement with Outrigger pursuant to which Outrigger manages our Waikele Center and Shops at Kalakaua. In connection with such management agreement, we pay Outrigger a fixed management fee of $12,000 per month in the aggregate plus additional amounts for any lease renewal services provided by Outrigger at our request. This management agreement can be terminated by us at any time and for any reason on 30 days' notice without any cancellation or termination fees.

A wholly owned subsidiary of our Operating Partnership, WBW Hotel Lessee LLC, entered into a franchise license agreement with Embassy Suites Franchise LLC, the franchisor of the brand “Embassy Suites™,” to obtain the non-exclusive right to operate the hotel under the Embassy SuitesTM brand for 20 years. The franchise license agreement provides that WBW Hotel Lessee LLC must comply with certain management, operational, record keeping, accounting, reporting and marketing standards and procedures. In connection with this agreement, we are also subject to the terms of a product improvement plan pursuant to which we expect to undertake certain actions to ensure that our hotel's infrastructure is maintained in compliance with the franchisor's brand standards. In addition, we must pay to Embassy Suites Franchise LLC a monthly franchise royalty fee equal to 5.0% of the hotel's gross room revenue, as well as a monthly program fee equal to 4.0% of the hotel's gross room revenue. If the franchise license is terminated due to our failure to make required improvements or to otherwise comply with its terms, we may be liable to the franchisor for a termination payment, which could be as high as $7.9 million based on operating performance through March 31, 2024.

Our Del Monte Center property has ongoing environmental remediation related to ground water contamination. The environmental issue existed at purchase and remains in remediation. The final stages of the remediation will include routine, long term ground monitoring by the appropriate regulatory agency over the next several years. The work performed is financed through an escrow account funded by the seller upon purchase of Del Monte Center. We believe the funds in the escrow account are sufficient for the remaining work to be performed. However, if further work is required that costs more than the remaining escrow funds, we may be required to pay such overage, although we may have a contractual claim for such costs against the prior owner or our environmental remediation consultant.

Concentrations of Credit Risk

Our properties are located in Southern California, Northern California, Washington, Oregon, Texas and Hawaii. The ability of the tenants to honor the terms of their respective leases is dependent upon the economic, regulatory, social, and health factors affecting the markets in which the tenants operate. Fifteen of our consolidated properties are located in Southern California, which exposes us to greater economic risks than if we owned a more geographically diverse portfolio. Tenants in the office industry accounted for 46.7% of total revenues for the three months ended March 31, 2024. This makes us susceptible to demand for office rental space and subject to the risks associated with an investment in real estate with a concentration of tenants in the office industry. Furthermore, tenants in the retail industry accounted for 23.5% of total revenues for the three months ended March 31, 2024. This makes us susceptible to demand for retail rental space and subject to the risks associated with an investment in real estate with a concentration of tenants in the retail industry. For the three months ended March 31, 2024 and 2023, no tenant accounted for more than 10% of our total rental revenue.

LEASES

LEASES

Lessor Operating Leases

We determine if an arrangement is a lease at inception. Our lease agreements are generally for real estate, and the determination of whether such agreements contain leases generally does not require significant estimates or judgments. We lease real estate under operating leases.

Our leases with office, retail, mixed-use and residential tenants are classified as operating leases. Leases at our office and retail properties and the retail portion of our mixed-use property generally range from three years to ten years (certain leases with anchor tenants may be longer), and in addition to minimum rents, usually provide for cost recoveries for the tenant’s share of certain operating costs. Our leases may also include variable lease payments in the form of percentage rents based on the tenant’s level of sales achieved in excess of a breakpoint threshold. Leases on apartments generally range from seven months to fifteen months, with a majority having 12-month lease terms. Rooms at the hotel portion of our mixed-use property are rented on a nightly basis.

Leases at our office and retail properties and the retail portion of our mixed-use property may contain lease extension options, at our lessee's discretion. The extension options are generally for 3 to 10 years and contain primarily rent at fixed rates or the prevailing market rent. The extension options are generally exercisable 6 to 12 months prior to the expiration of the lease and require the lessee to not be in default of the lease terms.

We attempt to maximize the amount we expect to derive from the underlying real estate property following the end of a lease, to the extent it is not extended.  We maintain a proactive leasing and capital improvement program that, combined with

the quality and locations of our properties, has made our properties attractive to tenants. However, the residual value of a real estate property is still subject to various market-specific, asset-specific, and tenant-specific risks and characteristics. 

As of March 31, 2024, minimum future rentals from noncancelable operating leases, before any reserve for uncollectible amounts and assuming no early lease terminations, at our office and retail properties and the retail portion of our mixed-use property are as follows for the years ended December 31 (in thousands):

 

2024 (nine months ending December 31, 2024)	$	187,854

The lease payments under the extension option provided for under the Annex Lease will be equal to the fair rental value at the time the extension option is exercised. The extension option is included in the calculation of the right-of-use asset and lease liability as we are reasonably certain of exercising the extension option.

Our lease agreements do not contain any residual value guarantees or material restrictive covenants. As our leases do not provide an implicit rate, we use our incremental borrowing rate based on the information available at commencement in determining the present value of lease payments.

RELATED PARTY TRANSACTIONS

During the third quarter of 2020, we entered into a lease with American Assets, Inc. ("AAI"), an entity owned and controlled by Ernest Rady, our Chief Executive Officer and Chairman of the Board, for office space at Torrey Point to replace a previously existing lease with AAI at Torrey Reserve Campus. Rents commenced on March 1, 2021 for an initial lease term of ten years at an average annual rental rate of $0.2 million. Rental revenue recognized on the AAI lease of $0.1 million and $0.1 million for the three months ended March 31, 2024 and 2023, respectively, is included in rental income on the statements of comprehensive income.

On occasion, the company utilizes aircraft services provided by AAI Aviation, Inc. ("AAIA"), an entity owned and controlled by Mr. Rady. For the three months ended March 31, 2024 and 2023, we incurred approximately $0.02 million and $0.1 million of expenses, respectively, related to aircraft services of AAIA or reimbursement to Mr. Rady (or his trust) for use of the aircraft owned by AAIA. These expenses are recorded as general and administrative expenses in our consolidated statements of comprehensive income.

The Waikiki Beach Walk entities have a 47.7% investment in WBW CHP LLC, an entity that was formed to, among other things, construct a chilled water plant to provide air conditioning to the property and other adjacent facilities. The operating expenses of WBW CHP LLC are recovered through reimbursements from its members, and reimbursements to WBW CHP LLC of $0.3 million and $0.3 million for the three months ended March 31, 2024 and 2023, respectively, are included in rental expenses on the consolidated statements of comprehensive income.

Segment Reporting [Abstract]

SEGMENT REPORTING

SEGMENT REPORTING

Segment information is prepared on the same basis that our management reviews information for operational decision-making purposes. We operate in four business segments: the acquisition, redevelopment, ownership and management of office real estate, retail real estate, multifamily real estate and mixed-use real estate. 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 retail segment primarily include rental of retail 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.

We evaluate the performance of our segments based on segment profit, which is defined as property revenue less property expenses. We do not use asset information as a measure to assess performance and make decisions to allocate resources. Therefore, depreciation and amortization expense is not allocated among segments. General and administrative expenses, interest expense, depreciation and amortization expense and other income and expense are not included in segment profit as our internal reporting addresses these items on a corporate level.

Segment profit is not a measure of operating income or cash flows from operating activities as measured by GAAP, and it is not indicative of cash available to fund cash needs and should not be considered an alternative to cash flows as a measure of liquidity. Not all companies calculate segment profit in the same manner. We consider segment profit to be an appropriate supplemental measure to net income because it assists both investors and management in understanding the core operations of our properties.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)

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 230 employees providing substantial in-house expertise in asset management, property management, property development, leasing, tenant improvement construction, acquisitions, repositioning, redevelopment and financing.

As of March 31, 2024, 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 March 31, 2024, we owned land at three of our properties that we classify as held for development and/or construction in progress. A summary of the properties owned by us is as follows:

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”) and 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, 2023.

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 chief operating decision maker reviews information for operational decision-making purposes. We operate in four business segments: the acquisition, redevelopment, ownership and management of office real estate, retail real estate, multifamily real estate and mixed-use real estate. 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 retail segment primarily include rental of retail 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.

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.

Recent Accounting Pronouncements

Recent Accounting Pronouncements

In November 2023, the FASB issued Accounting Standards Update (“ASU”) 2023-07, Improvements to Reportable Segment Disclosures. The pronouncement requires disclosure of significant segment expenses that are regularly provided to the chief operating decision maker and included within the segment measure of profit or loss. The pronouncement will be applied retrospectively and is effective for annual reporting periods in fiscal years beginning after December 15, 2023, and interim reporting periods in fiscal years beginning after December 31, 2024. We are currently evaluating the impact this pronouncement will have on our disclosures.

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.

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, restricted cash, 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 March 31, 2024 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.
