| SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES | 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 (the “Offering”) and the related acquisition on January 19, 2011 of certain assets of a combination of entities whose assets included entities owned and/or controlled by Ernest S. Rady and his affiliates, including the Rady Trust, which in turn owned (1) controlling interests in entities owning 17 properties and the property management business of American Assets, Inc. and (2) noncontrolling interests in entities owning four properties. 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 REIT subsidiary. 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 vertically integrated and self-administered REIT with 194 employees providing substantial in-house expertise in asset management, property management, property development, leasing, tenant improvement construction, acquisitions, repositioning, redevelopment and financing. Any reference to the number of properties or units, square footage or acres, employees; or references to beneficial ownership interests, are unaudited and outside the scope of our independent registered public accounting firm's audit of our financial statements in accordance with the standards of the United States Public Company Accounting Oversight Board. As of December 31, 2017, we owned or had a controlling interest in 26 office, retail, multifamily and mixed-use operating properties, the operations of which we consolidate. Additionally, as of December 31, 2017, we owned land at four of our properties that we classify as held for development and construction in progress. A summary of the properties owned by us is as follows:
Basis of Presentation Our consolidated financial statements include the accounts of the company, our Operating Partnership and our subsidiaries. The equity interests of other investors in our Operating Partnership are reflected as noncontrolling interests. All significant intercompany transactions and balances are eliminated in consolidation. Use of Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America, referred to as “GAAP,” requires management 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 management's best judgment, after considering past, current and expected events and economic conditions. Actual results could differ from these estimates. Consolidated Statements of Cash Flows-Supplemental Disclosures The following table provides supplemental disclosures related to the Consolidated Statements of Cash Flows (in thousands):
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. When we determine that we are the owner of tenant improvements and the tenant has reimbursed us for a portion or all of the tenant improvement costs, we consider the amount paid to be additional rent, which is recognized on a straight-line basis over the term of the related lease. For first generation tenants, in instances in which we fund tenant improvements and the improvements are deemed to be owned by us, revenue recognition will commence when the improvements are substantially completed and possession or control of the space is turned over to the tenant. When we determine that the tenant is the owner of tenant improvements, tenant allowances are recorded as lease incentives and we commence revenue recognition and lease incentive amortization when possession or control of the space is turned over to the tenant for tenant work to begin. Percentage rents, which represent additional rents based upon the level of sales achieved by certain tenants, are recognized at the end of the lease year or earlier if we have determined the required sales level is achieved and the percentage rents are collectible. Real estate tax and other cost reimbursements are recognized on an accrual basis over the periods in which the related expenditures are incurred. Other property income includes parking income, general excise tax billed to tenants and fees charged to tenants at our multifamily properties. Other property income is recognized when earned. We recognize general excise tax gross, with the amounts billed to tenants and customers recorded in other property income and the related taxes paid as rental expense. The general excise tax included in other income was $3.7 million, $3.8 million and $3.7 million for the years ended December 31, 2017, 2016 and 2015, respectively. For a tenant to terminate its lease agreement prior to the end of the agreed term, we may require that they pay a fee to cancel the lease agreement. Lease termination fees for which the tenant has relinquished control of the space are generally recognized on the termination date. When a lease is terminated early but the tenant continues to control the space under a modified lease agreement, the lease termination fee is generally recognized evenly over the remaining term of the modified lease agreement. We recognize revenue on the hotel portion of our mixed-use property from the rental of hotel rooms and guest services when the rooms are occupied and services have been provided. Food and beverage sales are recognized when the customer has been served or at the time the transaction occurs. Revenue from room rental is included in rental revenue on the statement of income. Revenue from other sales and services provided is included in other property income on the statement of income. We make estimates of the collectability of our accounts receivable related to minimum rents, straight-line rents, expense reimbursements and other revenue. Accounts receivable and deferred rent receivable are carried net of this allowance for doubtful accounts. We generally do not require collateral or other security from our tenants, other than letters of credit or security deposits. Our determination as to the collectability of accounts receivable and correspondingly, the adequacy of this allowance, is based primarily upon evaluations of individual receivables, current economic conditions, historical experience and other relevant factors. The allowance for doubtful accounts is increased or decreased through bad debt expense. In some cases, primarily relating to straight-line rents, the collection of these amounts extends beyond one year. Our experience relative to unbilled straight-line rents is that a portion of the amounts otherwise recognizable as revenue is never billed to or collected from tenants due to early lease terminations, lease modifications, bankruptcies and other factors. Accordingly, the extended collection period for straight-line rents along with our evaluation of tenant credit risk may result in the nonrecognition of a portion of straight-line rental income until the collection of such income is reasonably assured. If our evaluation of tenant credit risk changes indicating more straight-line revenue is reasonably collectible than previously estimated and realized, the additional straight-line rental income is recognized as revenue. If our evaluation of tenant credit risk changes indicating a portion of realized straight-line rental income is no longer collectible, a reserve and bad debt expense is recorded. At December 31, 2017 and December 31, 2016, our allowance for doubtful accounts was $0.4 million and $0.4 million, respectively. Our allowance for deferred rent receivables at December 31, 2017 and December 31, 2016 was $1.4 million and $1.3 million, respectively. Total bad debt expense was $0.8 million, $0.8 million and $0.4 million for the years ended December 31, 2017, 2016 and 2015, respectively. We recognize gains on sales of properties upon the closing of the transaction with the purchaser. Gains on properties sold are recognized using the full accrual method when (1) the collectability of the sales price is reasonably assured, (2) we are not obligated to perform significant activities after the sale, (3) the initial investment from the buyer is sufficient and (4) other profit recognition criteria have been satisfied. Gains on sales of properties may be deferred in whole or in part until the requirements for gain recognition have been met. Real Estate Land, buildings and improvements are recorded at cost. Depreciation is computed using the straight-line method. Estimated useful lives range generally from 30 years to a maximum of 40 years on buildings and major improvements. Minor improvements, furniture and equipment are capitalized and depreciated over useful lives ranging from 3 years to 15 years. Maintenance and repairs that do not improve or extend the useful lives of the related assets are charged to operations as incurred. Tenant improvements are capitalized and depreciated over the life of the related lease or their estimated useful life, whichever is shorter. If a tenant vacates its space prior to the contractual termination of its lease, the undepreciated balance of any tenant improvements are written off if they are replaced or have no future value. For the years ended December 31, 2017, 2016 and 2015, real estate depreciation expense was $70.2 million, $62.5 million and $54.2 million, respectively. Acquisitions of properties are accounted for in accordance with the authoritative accounting guidance on acquisitions and business combinations. Our methodology of allocating the cost of acquisitions to assets acquired and liabilities assumed is based on estimated fair values, replacement cost and appraised values. When we acquire operating real estate properties, the purchase price is allocated to land and buildings, intangibles such as in-place leases, and to current assets and liabilities acquired, if any. Such valuations include a consideration of the noncancelable terms of the respective leases as well as any applicable renewal periods. The fair values associated with below market renewal options are determined based on a review of several qualitative and quantitative factors on a lease-by-lease basis at acquisition to determine whether it is probable that the tenant would exercise its option to renew the lease agreement. These factors include: (1) the type of tenant in relation to the property it occupies, (2) the quality of the tenant, including the tenant's long term business prospects and (3) whether the fixed rate renewal option was sufficiently lower than the fair rental of the property at the date the option becomes exercisable such that it would appear to be reasonably assured that the tenant would exercise the option to renew. The value allocated to in-place leases is amortized over the related lease term and reflected as depreciation and amortization in the statement of income. The value of above and below market leases associated with the original noncancelable lease terms are amortized to rental income over the terms of the respective noncancelable lease periods and are reflected as either an increase (for below market leases) or a decrease (for above market leases) to rental income in the statement of income. The value of the leases associated with below market lease renewal options that are likely to be exercised are amortized to rental income over the respective renewal periods. If a tenant vacates its space prior to contractual termination of its lease or the lease is not renewed, the unamortized balance of any in-place lease value is written off to rental income and amortization expense. Transaction costs related to the acquisition of a business, such as broker fees, transfer taxes, legal, accounting, valuation, and other professional and consulting fees, are expensed as incurred and included in “general and administrative expenses” in our consolidated statements of comprehensive income. For asset acquisitions not meeting the definition of a business, transaction costs are capitalized as part of the acquisition cost. Capitalized Costs We capitalize certain costs related to the development and redevelopment of real estate including pre-construction costs, real estate taxes, insurance and construction costs and salaries and related costs of personnel directly involved. Additionally, we capitalize interest costs related to development and significant redevelopment activities. Capitalization of these costs begins when the activities and related expenditures commence and cease when the project is substantially complete and ready for its intended use, at which time the project is placed in service and depreciation commences. Additionally, we make estimates as to the probability of certain development and redevelopment projects being completed. If we determine that the completion of development or redevelopment is no longer probable, we expense all capitalized costs which are not recoverable. Impairment of Long Lived Assets We review for impairment on a property by property basis whenever events or changes in circumstances indicate that the carrying value of a property may not be fully recoverable. Impairment is recognized on properties held for use when the expected undiscounted cash flows for a property are less than its carrying amount at which time the property is written-down to fair value. Properties held for sale are recorded at the lower of the carrying amount or the expected sales price less costs to sell. There were no impairment charges during the years ended December 31, 2017, December 31, 2016 and December 31, 2015. Financial Instruments The estimated fair values of financial instruments are determined using available market information and appropriate valuation methods. Considerable judgment is necessary to interpret market data and develop estimated fair values. The use of different market assumptions or estimation methods may have a material effect on the estimated fair value amounts. Accordingly, estimated fair values are not necessarily indicative of the amounts that could be realized in current market exchanges. Derivative Instruments At times, we may use derivative instruments to manage exposure to variable interest rate risk. We may enter into interest rate swaps to manage our exposure to variable interest rate risk. If and when we enter into derivative instruments, we ensure that such instruments qualify as cash flow hedges and would not enter into derivative instruments for speculative purposes. Any interest rate swaps associated with our cash flow hedges are recorded at fair value on a recurring basis. We assess effectiveness of our cash flow hedges both at inception and on an ongoing basis. The effective portion of changes in fair value of the interest rate swaps associated with our cash flow hedges is recorded in accumulated other comprehensive income (loss) and is subsequently reclassified into interest expense as interest is incurred on the related variable rate debt. Our cash flow hedges become ineffective if critical terms of the hedging instrument and the debt instrument do not perfectly match such as notional amounts, settlement dates, reset dates, calculation period and LIBOR rate. In addition, we evaluate the default risk of the counterparty by monitoring the credit worthiness of the counterparty. When ineffectiveness exists, the ineffective portion of changes in fair value of the interest rate swaps associated with our cash flow hedges is recognized in earnings in the period affected. See the discussion under Note 8 for certain quantitative details related to interest rate swaps and for a discussion on how we value derivative financial instruments. Cash and Cash Equivalents We define cash and cash equivalents as cash on hand, demand deposits with financial institutions and short term liquid investments with an initial maturity of less than 3 months. Cash balances in individual banks may exceed the federally insured limit of $250,000 by the Federal Deposit Insurance Corporation (the "FDIC"). No losses have been experienced related to such accounts. At December 31, 2017 and December 31, 2016, we had $45.7 million and $37.1 million, respectively, in excess of the FDIC insured limit. At December 31, 2017 and December 31, 2016, we had $29.4 million and $0.2 million, respectively, in money market funds that are not FDIC insured. Restricted Cash Restricted cash consists of amounts held by lenders to provide for future real estate tax expenditures, insurance expenditures and reserves for capital improvements. At December 31, 2017 and 2016, we had $9.3 million and $10.0 million, respectively, in restricted cash. Other Assets Other assets consist primarily of lease costs, lease incentives, acquired in-place leases and acquired above market leases. Capitalized lease costs are direct costs incurred which were essential to originate a lease and would not have been incurred had the leasing transaction not taken place and include third party commissions related to obtaining a lease. Capitalized lease costs are amortized over the life of the related lease and included in depreciation and amortization expense on the statement of income. If a tenant vacates its space prior to the contractual termination of its lease, the unamortized balance of any lease costs are written off. We view these lease costs as part of the up-front initial investment we made in order to generate a long-term cash inflow. Therefore, we classify cash outflows for lease costs as an investing activity in our consolidated statements of cash flows. Variable Interest Entities Certain entities that do not have sufficient equity at risk for the entity to finance its activities without additional subordinated financial support from other parties or in which equity investors do not have the characteristics of a controlling financial interest qualify as variable interest entities (“VIEs”). VIEs are required to be consolidated by their primary beneficiary. The primary beneficiary of a VIE is the party that has a controlling interest in the VIE. Identifying the party with the controlling interest requires a focus on which entity has the power to direct the activities of the VIE that most significantly impact the VIE's economic performance and (1) the obligation to absorb the expected losses of the VIE or (2) the right to receive the benefits from the VIE. At December 31, 2017 and December 31, 2016 we had no investments in real estate joint ventures, and accordingly we had no VIEs which needed to be consolidated. Stock-Based Compensation We grant stock-based compensation awards to our employees and directors typically in the form of restricted shares of common stock, options to purchase common stock and/or shares of common stock. We measure stock-based compensation expense based on the fair value of the award on the grant date and recognize the expense ratably over the vesting period. Modifications of stock-based compensation awards are treated as an exchange of the original award for a new award with the resulting total compensation cost equal to the grant-date fair value of the original award plus the incremental value of the modification to the award. The calculation of the incremental value is based on the excess of the fair value of the new (modified) award based on current circumstances over the fair value of the original option measured immediately before its terms are modified. For the year ended December 31, 2017, we incurred incremental compensation cost of approximately $2.2 million related to the discretionary vesting of previously granted restricted stock awards that did not meet the original vesting criteria. For the year ended December 31, 2016 and 2015, there were no modifications of stock-based compensation awards. Deferred Compensation Our Operating Partnership has adopted the American Assets Trust Executive Deferral Plan V (“EDP V”) and the American Assets Trust Executive Deferral Plan VI (“EDP VI”). These plans were adopted by our Operating Partnership as successor plans to those deferred compensation plans maintained by American Assets Inc. ("AAI") in which certain employees of AAI, who were transferred to us in connection with the Offering (the “Transferred Participants”), participated prior to the Offering. EDP V and EDP VI contain substantially the same terms and conditions as these predecessor plans. AAI transferred to our Operating Partnership the Transferred Participants' account balances under the predecessor plans. These transferred account balances represent amounts deferred by the Transferred Participants prior to the Offering while they were employed by AAI. At the time eligible participants defer compensation, we record compensation cost and a corresponding deferred compensation plan liability, which is included in other liabilities and deferred credits on our consolidated balance sheets. This liability is adjusted to fair value at the end of each accounting period based on the performance of the benchmark funds selected by each participant, and the impact of adjusting the liability to fair value is recorded as an increase or decrease to compensation cost. Income Taxes We elected to be taxed as a REIT under the Internal Revenue Code of 1986, as amended (the “Code”) commencing with the taxable year ending December 31, 2011. To maintain our qualification as a REIT, we are required to distribute at least 90% of our REIT taxable income to our stockholders and meet the various other requirements imposed by the Code relating to such matters as operating results, asset holdings, distribution levels and diversity of stock ownership. Provided we maintain our qualification for taxation 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. If we fail to maintain our qualification as a REIT in any taxable year, and are unable to avail ourselves of certain savings provisions set forth in the Code, all of our taxable income would be subject to regular U.S. federal income tax. We are subject to certain state and local income taxes. We, together with one of our subsidiaries, have elected to treat such subsidiary as a taxable REIT subsidiary (a “TRS”) for federal income tax purposes. Certain activities that we undertake must be conducted by a TRS, such as non-customary services for our tenants, and holding assets that we cannot hold directly. A TRS is subject to federal and state income taxes. Segment Information Segment information is prepared on the same basis that our management reviews information for operational decision-making purposes. We operate in four reportable segments: the acquisition, redevelopment, ownership and management of retail real estate, office real estate, multifamily real estate and mixed-use real estate. The products for our retail segment primarily include rental of retail space and other tenant services, including tenant reimbursements, parking and storage space rental. The products for our office segment primarily include rental of office space and other tenant services, including tenant reimbursements, parking and storage space rental. The products for our multifamily segment include rental of apartments and other tenant services. The products of our mixed-use segment include rental of retail space and other tenant services, including tenant reimbursements, parking and storage space rental and operation of a 369-room all-suite hotel. Recent Accounting Pronouncements In August 2017, the FASB issued Accounting Standards Update (“ASU”) 2017-12, Derivatives and Hedging: Targeted Improvements to Accounting for Hedging Activities. The pronouncement was issued to simplify the on-going assessment of hedge effectiveness and increase transparency related to hedge accounting. The pronouncement is effective for fiscal years, and for interim periods within those fiscal years, beginning after December 15, 2018, with early adoption permitted. The company early adopted the provisions of ASU No. 2017-12 effective October 1, 2017 using the modified retrospective approach. The company determined there is no impact to the company’s historical results as a result of adoption of the new standard and therefore no adjustment to retained earnings from application of the ASU. In January 2017, the FASB issued ASU 2017-1, Business Combinations: Clarifying the Definition of a Business. The pronouncement changes the definition of a business to assist entities with evaluating when a set of transferred assets and activities is a business. The pronouncement requires an entity to evaluate if substantially all of the fair value of the gross assets acquired is concentrated in a single identifiable asset or a group of similar identifiable assets; if so, the set of transferred assets and activities is not a business. The pronouncement is effective for fiscal years, and for interim periods within those fiscal years, beginning after December 15, 2018, with early adoption permitted. The company early adopted this ASU effective January 1, 2017. For the period from January 1, 2017 through December 31, 2017, the company acquired three properties for which we concluded that substantially all of the fair value of the assets acquired were concentrated in a single identifiable asset and that the assets therefore did not meet the definition of a business under ASU 2017-01. Acquisition transaction costs associated with these property acquisitions were approximately $0.2 million and were capitalized to real estate investments. In November 2016, the FASB issued ASU 2016-18, Restricted Cash. This pronouncement requires companies to include restricted cash and restricted cash equivalents with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flows. The pronouncement also requires a disclosure of a reconciliation between the statement of financial position and the statement of cash flows when the balance sheet includes more than one line item for cash, cash equivalents, restricted cash, and restricted cash equivalents. Entities with material restricted cash and restricted cash equivalents balances will be required to disclose the nature of the restrictions. The ASU is effective for reporting periods beginning after December 15, 2017, with early adoption permitted, and will be applied retrospectively to all periods presented. The company adopted this ASU effective December 31, 2017. The adoption of this ASU impacted the presentation of cash flows with inclusion of restricted cash flows for each of the presented periods. As of December 31, 2017 and December 31, 2016 , we had $9.3 million and $10.0 million of restricted cash, respectively, on our consolidated balance sheets. In March 2016, the FASB issued ASU 2016-09, Improvements to Employee Share-Based Payment Accounting, which simplifies several aspects of the accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. ASU 2016-09 is effective for fiscal years beginning after December 15, 2016, and interim periods within those fiscal years. The company adopted this ASU effective January 1, 2017 and the adoption did not have a material impact on our consolidated financial statements. In February 2016, the FASB issued ASU No. 2016-2, Leases. This pronouncement is expected to result in the recognition of a right-to-use asset and related liability to account for future obligations under ground lease agreements for which the Company is the lessee. In addition, this pronouncement will require that lessees and lessors capitalize, as initial direct costs, only those costs that are incurred due to the execution of a lease. As of December 31, 2017, the remaining contractual payments under lease agreements for which the company is the lessee aggregated approximately $38.3 million. As a lessor, under current accounting standards, the company recognizes rental revenue from our operating leases on a straight-line basis over the respective lease terms. The company commences recognition of rental revenue at the date the property is ready for its intended use and the tenant takes possession of or controls the physical use of the property. Under current accounting standards, tenant recoveries related to payments of real estate taxes, insurance, utilities, repairs and maintenance, common area expenses, and other operating expenses are considered lease components. The company recognizes these tenant recoveries as revenue when services are rendered in an amount equal to the related operating expenses incurred that are recoverable under the terms of the applicable lease. Under this pronouncement, each lease agreement will be evaluated to identify the lease components and nonlease components at lease inception. The total consideration in the lease agreement will be allocated to the lease and nonlease components based on their relative standalone selling prices. Lessors will continue to recognize the lease revenue component using an approach that is substantially equivalent to existing guidance for operating leases (straight-line basis). In January 2018, the FASB issued a proposed amendment to the lease ASU that would allow lessors to elect, as a practical expedient, not to allocate the total consideration to lease and nonlease components based on their relative standalone selling prices. If adopted, this practical expedient will allow lessors to elect a combined single lease component presentation if (i) the timing and pattern of the revenue recognition of the combined single lease component is the same, and (ii) the related lease component and, the combined single lease component would be classified as an operating lease. The pronouncement is effective for fiscal years, and for interim periods within those fiscal years, beginning after December 15, 2018, with early adoption permitted. The company plans to adopt the provisions of ASU No. 2016-2 effective January 1, 2019 using the modified retrospective approach. The company continues to evaluate the impact this pronouncement will have on the company’s consolidated financial statements. In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers. The pronouncement was issued to clarify the principles for recognizing revenue and to develop a common revenue standard and disclosure requirements for U.S. GAAP and International Financial Reporting Standards. The pronouncement is effective for reporting periods beginning after December 15, 2017. The company will adopt the provisions of the ASU effective January 1, 2018 using the modified retrospective approach. As discussed above, leases are specifically excluded from this and will be governed by the applicable lease codification; however, this update may have implications on certain variable payment terms included in lease agreements. Upon adoption of the new lease ASU in 2019, we may be required to classify our tenant recoveries into lease and nonlease components, whereby the nonlease components would be subject to the revenue recognition ASU, pending the resolution of the proposed amendment issued by the FASB in January 2018. Property services categorized as nonlease components that are reimbursed by our tenants may need to be presented on a net basis if it is determined that we hold an agent arrangement. The Company evaluated the revenue recognition for all contracts within this scope under existing accounting standards and under the new revenue recognition ASU and confirmed that there were no differences in the amounts recognized or the pattern of recognition. This evaluation included revenues from the hotel portion of our mixed-use property, parking income and excise taxes charged to customers. Therefore, the adoption of this ASU did not result in an adjustment to the Company’s retained earnings on January 1, 2018. |

| 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:
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. Except as disclosed below, the carrying amount of our financial instruments approximates their fair value. Financial assets and liabilities whose fair values we measure on a recurring basis using Level 2 inputs consist of our deferred compensation liability and interest rate swap liability. We measure the fair values of these liabilities based on prices provided by independent market participants that are based on observable inputs using market-based valuation techniques provided by third parties using proprietary valuation models and analytical tools as of December 31, 2017 and 2016. These valuation models and analytical tools use market pricing or similar instruments that are both objective and publicly available, including matrix pricing or reported trades, benchmark yields, broker/dealer quotes, issuer spreads, two-sided markets, benchmark securities, bids and/or offers. 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):
The fair value of our secured notes payable and unsecured notes payable is sensitive to fluctuations in interest rates. Discounted cash flow analysis (Level 2) is generally used to estimate the fair value of our mortgages and notes payable, using rates ranging from 3.9% to 4.6%. 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 line of credit and term loan set forth below are deemed to be at fair value since the outstanding debt is directly tied to monthly LIBOR contracts. A summary of the carrying amount and fair value of our financial instruments, all of which are based on Level 2 inputs, is as follows (in thousands):

| DEBT | DEBT Debt of American Assets Trust, Inc. American Assets Trust, Inc. does not hold any indebtedness. All debt is held directly or indirectly by the Operating Partnership; however, American Assets Trust, Inc. has guaranteed the Operating Partnership's second amended and restated credit facility, term loan and carve-out guarantees on property-level debt. Debt of American Assets Trust, L.P. Secured notes payable The following is a summary of the Operating Partnership's total secured notes payable outstanding as of December 31, 2017 and December 31, 2016 (in thousands):
Certain loans require us to comply with various financial covenants, including the maintenance of minimum debt coverage ratios. As of December 31, 2017, we were in compliance with all loan covenants. Unsecured notes payable The following is a summary of the Operating Partnership's total unsecured notes payable outstanding as of December 31, 2017 and December 31, 2016 (in thousands):
On March 1, 2016, the Operating Partnership entered into a Term Loan Agreement with each lender from time to time party thereto, and U.S. Bank National Association, as Administrative Agent (as amended, the “Term Loan Agreement”). The Term Loan Agreement provides for a new, seven-year unsecured term loan to the Operating Partnership of $100 million that matures on March 1, 2023 (“Term Loan B”). Concurrent with the closing of the Term Loan Agreement, the Operating Partnership drew down the entirety of Term Loan B. On May 2, 2016, the Operating Partnership entered into a Joinder and First Amendment to the Term Loan Agreement to provide for a new lender to fund an incremental term loan. The Joinder and First Amendment provides for a new, seven-year unsecured term loan to the Operating Partnership of $50 million that matures on March 1, 2023 ("Term Loan C"). Term Loan C has the same borrowing terms as the Term Loan Agreement noted below. Concurrent with the closing of the Joinder and First Amendment, the Operating Partnership drew down the entirety of Term Loan C. Borrowings under the Term Loan Agreement with respect to Term Loan B and Term Loan C bear interest at floating rates equal to, at our option, either (1) LIBOR, plus a spread which ranges from 1.70% to 2.35% based on our consolidated leverage ratio, or (2) a base rate equal to the highest of (a) 0%, (b) the prime rate, (c) the federal funds rate plus 50 bps or (d) the Eurodollar rate plus 100 bps, in each case plus a spread which ranges from 0.70% to 1.35% based on our consolidated leverage ratio. The company entered into interest rate swap agreements intended to fix the interest rates associated with Term Loan B and Term Loan C at approximately 3.15% and 3.14%, respectively, through the maturity dates, subject to adjustments based on our consolidated leverage ratio. The 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 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. On January 9, 2018, we entered into the Third Amendment (“Third Amendment”) to the Term Loan Agreement, which maintains the seven-year $150 million unsecured term loan (Term Loan B and Term Loan C) to the Operating Partnership that matures on March 1, 2023 (the “$150mm Term Loan”). Effective as of March 1, 2018, borrowings under the Term Loan Agreement with respect to the $150mm Term Loan bear interest at floating rates equal to, at the Operating Partnership’s option, either (1) LIBOR, plus a spread which ranges from 1.20% to 1.70% based on the Operating Partnership’s consolidated leverage ratio, or (2) a base rate equal to the highest of (a) 0%, (b) the prime rate, (c) the federal funds rate plus 50 bps or (d) the Eurodollar rate plus 100 bps, in each case plus a spread which ranges from 0.70% to 1.35% based on the Operating Partnership’s consolidated leverage ratio. The foregoing rates are intended to be more favorable than previously contained in the Term Loan Agreement. Additionally, the Operating Partnership may elect for borrowings to bear interest based on a ratings-based pricing grid as per the Operating Partnership’s then-applicable investment grade debt ratings under the terms set forth in the Term Loan Agreement. 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 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 will 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 will 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," and collectively with the Series A Notes, Series B Notes, Series C Notes, Series D Notes and Series E Notes are referred to herein as, the “Notes".). The Series F Notes were issued on July 19, 2017 and will pay interest semi-annually on the 31st of January and July until their respective maturities. 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 (as defined in the Note Purchase Agreement). The Note Purchase 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 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 December 31, 2017, the Operating Partnership was in compliance with all loan covenants. Scheduled principal payments on secured and unsecured notes payable as of December 31, 2017 are as follows (in thousands):
Credit Facility On January 9, 2014, the company and the Operating Partnership entered into an amended and restated credit agreement (the "Prior Credit Facility"), or the amended and restated credit facility, which amended and restated the then in-place credit facility. The amended and restated credit facility provides for aggregate, unsecured borrowing of $350 million, consisting of a revolving line of credit of $250 million (the "Prior Revolver Loan") and a term loan of $100 million (the "Term Loan A"). The Prior Credit Facility had an accordion feature that allowed the Operating Partnership to increase the availability thereunder up to an additional $250 million, subject to meeting specified requirements and obtaining additional commitments from lenders. At December 31, 2017, there was no outstanding balance under the Prior Revolver Loan. On October 16, 2014, we entered into a first amendment to the Prior Credit Agreement that amended provisions of the Prior Credit Agreement to, among other things, (1) describe the treatment of our pari passu obligations under the amended and restated credit agreement and (2) remove the material acquisition provisions previously set forth in the Prior Credit Agreement. Borrowings under the Prior Credit Facility initially beared interest at floating rates equal to, at our option, either (1) LIBOR, plus a spread which ranges from (a) 1.35%-1.95% (with respect to the Prior Revolver Loan) and (b) 1.30% to 1.90% (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 or (c) the Eurodollar rate plus 100 bps, plus a spread which ranges from (i) 0.35%-0.95% (with respect to the Prior Revolver Loan) and (ii) 0.30% to 0.90% (with respect to Term Loan A), in each case based on our consolidated leverage ratio. The foregoing rates were more favorable than previously contained in the credit agreement in place as of December 31, 2013. If American Assets Trust, Inc. obtained an investment-grade debt rating, under the terms set forth in the Prior Credit Facility, the spreads would further improve. For the year-ended December 31, 2017, the weighted average interest rate on the Revolver Loan was 2.36%. The Prior Revolver Loan initially matured on January 9, 2018, subject to the Operating Partnership's option to extend the Prior Revolver Loan up to two times, with each such extension for a six-month period. The Term Loan initially matured on January 9, 2016, subject to our option to extend the Term Loan A up to three times, with each such extension for a 12-month period. The foregoing extension options are exercisable by us subject to the satisfaction of certain conditions. Effective as of January 8, 2018, the Operating Partnership exercised the third of three options to extend the maturity date of Term Loan A to January 9, 2019. Concurrent with the closing of the Prior Credit Facility, the Operating Partnership drew down on the entirety of the $100 million Term Loan, which remains outstanding and is included in unsecured notes payable as discussed above. Additionally, the Prior Credit Facility included a number of financial covenants, including:
The Prior Credit Facility provided that American Assets Trust, Inc.'s 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. American Assets Trust, Inc. and certain of its subsidiaries guaranteed the obligations under the Prior Credit Agreement, and certain of its subsidiaries pledged specified equity interests in our subsidiaries as collateral for our obligations under the Prior Credit Facility. As of December 31, 2017, the Operating Partnership was in compliance with all then in-place Prior Credit Facility covenants. On January 9, 2018, we entered into a second amended and restated credit agreement (the "Second Amended and Restated Credit Facility"), which amended and restated the Prior Credit Agreement. The Second Amended and Restated Credit Facility provides for aggregate, unsecured borrowing of $450 million, consisting of a revolving line of credit of $350 million (the "Revolver Loan") and a term loan of $100 million (the "Term Loan A"). The Second Amended and Restated Credit Facility has an accordion feature that may allow us to increase the availability thereunder up to an additional $350 million, subject to meeting specified requirements and obtaining additional commitments from lenders. Borrowings under the Second Amended and Restated Credit Agreement initially bear interest at floating rates equal to, at our option, either (1) LIBOR, plus a spread which ranges from (a) 1.05% to 1.50% (with respect to the Revolver Loan) and (b) 1.30% to 1.90% (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 or (c) LIBOR plus 100 bps, plus a spread which ranges from (i) 0.10% to 0.50% (with respect to the Revolver Loan) and (ii) 0.30% to 0.90% (with respect to Term Loan A), in each case based on our consolidated leverage ratio. The foregoing rates are more favorable than previously contained in the Prior Credit Facility in place as of December 31, 2017. The Revolver Loan initially matures on January 9, 2022, subject to our option to extend the Revolver Loan up to two times, with each such extension for a six-month period. The Term Loan A matures on January 9, 2019. The foregoing extension options are exercisable by us subject to the satisfaction of certain conditions. Additionally, the Second Amended and Restated Credit Facility includes a number of customary financial covenants, including:
The Second Amended and Restated Credit Facility provides that our annual distributions may not exceed the greater of (1) 95% of our 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. |

| 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 exposure to interest rate movement. To accomplish these objectives, we 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. Concurrent with the closing of our amended and restated credit facility, we entered into an interest rate swap agreement that is intended to fix the interest rate associated with our term loan of $100 million at approximately 3.08% through its maturity date and extension options, subject to adjustments based on our consolidated leverage ratio. On January 29, 2016, we entered into a forward-starting interest rate swap contract with U.S. Bank National Association to reduce the interest rate variability exposure of the projected interest cash flows of our then prospective $100 million seven-year term loan. The forward-starting seven-year swap contract had a notional amount of $100 million, a termination date of March 1, 2023, a fixed pay rate of 1.4485%, and a receive rate equal to the one-month LIBOR, with fixed rate payments due monthly commencing April 1, 2016, floating payments due monthly commencing April 1, 2016, and floating reset dates two days prior to the first day of each calculation period. The forward-starting seven-year swap contract accrual period, March 1, 2016 to March 1, 2023, was designed to match the expected tenor of our then prospective $100 million seven-year term loan, which successfully closed on March 1, 2016. On March 23, 2016, we entered into a forward-starting interest rate swap contract with Wells Fargo Bank, National Association to reduce the interest rate variability exposure of the projected interest cash flows of our then prospective incremental $50 million seven-year term loan. The forward-starting seven-year swap contract had a notional amount of $50 million, a termination date of March 1, 2023, a fixed pay rate of 1.4410%, and a receive rate equal to the one-month LIBOR, with fixed rate payments due monthly commencing June 1, 2016, floating payments due monthly commencing June 1, 2016, and floating reset dates two days prior to the first day of each calculation period. The forward-starting seven-year swap contract accrual period, May 2, 2016 to March 1, 2023, was designed to match the expected tenor of our then prospective incremental $50 million seven-year term loan, which successfully closed on May 2, 2016. On March 29, 2016, we entered into a forward-starting interest rate swap contract with Wells Fargo Bank, National Association to reduce the interest rate variability exposure of the projected interest cash flows of our prospective new ten-year debt offering (private placement, investment grade bonds, term loan or otherwise) (anticipated to close on or before March 31, 2017). The forward-starting ten-year swap contract had a notional amount of $150 million, a termination date of March 31, 2027, a fixed pay rate of 1.8800%, and a receive rate equal to the three-month LIBOR, with fixed rate payments due semi-annually commencing September 29, 2017, floating payments due semi-annually commencing September 29, 2017, and floating reset dates the first day of each quarterly period. The forward-starting ten-year swap contract accrual period, March 31, 2017 to March 31, 2027, was designed to match the expected tenor of our prospective new ten-year debt offering (private placement, investment grade bonds, term loan or otherwise). There can be no assurances that the prospective debt offering described above will close on the terms described herein, or at all. On April 7, 2016, we entered into a forward-starting interest rate swap contract with Wells Fargo Bank, National Association to reduce the interest rate variability exposure of the projected interest cash flows of our prospective new ten-year debt offering (private placement, investment grade bonds, term loan or otherwise) (anticipated to close on or before March 31, 2017). The forward-starting ten-year swap contract had a notional amount of $100 million, a termination date of March 31, 2027, a fixed pay rate of 1.7480%, and a receive rate equal to the three-month LIBOR, with fixed rate payments due semi-annually commencing September 29, 2017, floating payments due semi-annually commencing September 29, 2017, and floating reset dates the first day of each quarterly period. The forward-starting ten-year swap contract accrual period, March 31, 2017 to March 31, 2027, was designed to match the expected tenor of our prospective new ten-year debt offering (private placement, investment grade bonds, term loan or otherwise). There can be no assurances that the prospective debt offering described above will close on the terms described herein, or at all. On January 18, 2017, we settled the March 29, 2016 $150 million and April 7, 2016 $100 million ten-year forward-starting interest rate swaps resulting in an aggregate gain of approximately $10.4 million. This gain is included in accumulated other comprehensive income and will be amortized to interest expense over the life of the Series D Notes. The forward-starting interest rate swap contracts have been deemed to be highly effective cash flow hedges and we elected to designate all the forward-starting swap contracts as accounting hedges. On April 25, 2017, we entered into a treasury lock contract (the "April 2017 Treasury Lock") with Bank of America, National Association, to reduce the interest rate variability exposure of the projected interest cash flows of our then prospective new twelve-year private placement. The April 2017 Treasury Lock had a notional amount of $100 million, termination date of May 18, 2017, a fixed pay rate of 2.313%, and a receive rate equal to the ten-year treasury rate on the settlement date. On May 11, 2017, we settled the April 2017 Treasury Lock, resulting in a gain of approximately $0.7 million. This gain is included in accumulated other comprehensive income and will be amortized to interest expense over ten years. The April 2017 Treasury Lock has been deemed to be a highly effective cash flow hedge and we elected to designate the April 2017 Treasury Lock as an accounting hedge. On May 31, 2017, we entered into a treasury lock contract (the "May 2017 Treasury Lock") with Bank of America, National Association, to reduce the interest rate variability exposure of the projected interest cash flows of our then prospective new seven-year private placement. The May 2017 Treasury Lock had a notional amount of $100 million, termination date of July 26, 2017, a fixed pay rate of 2.064%, and a receive rate equal to the seven-year treasury rate on the settlement date. On June 23, 2017, we settled the May 2017 Treasury Lock, resulting in a loss of approximately $0.5 million. This loss is included in accumulated other comprehensive income and will be amortized to interest expense over seven years. The May 2017 Treasury Lock has been deemed to be a highly effective cash flow hedge and we elected to designate the May 2017 Treasury Lock as an accounting hedge. The forward-starting interest rate swap contracts have been deemed to be highly effective cash flow hedges and we elected to designate all the forward-starting swap contracts as accounting hedges. The following is a summary of the terms of the interest rate swap as of December 31, 2017 (dollars in thousands):
The effective portion of changes in the fair value of the derivatives that are designated as cash flow hedges are being recorded as accumulated other comprehensive income and will be subsequently reclassified into earnings during the period in which the hedged forecasted transaction affects earnings. 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 uses observable market-based inputs, including interest rate curves, and implied volatilities. The fair value of the interest rate swaps 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. |

| Equity [Abstract] | |
| PARTNERS' CAPITAL OF AMERICAN ASSETS TRUST, L.P. | PARTNERS' CAPITAL OF AMERICAN ASSETS TRUST, L.P. As of December 31, 2017, the Operating Partnership had 17,194,980 common units (the “Noncontrolling Common Units”) outstanding. American Assets Trust, Inc. owned 73.2% of the Operating Partnership at December 31, 2017. The remaining 26.8% of the partnership interests are owned by non-affiliated investors and certain of our directors and executive officers. Common units and shares of the company's common stock have essentially the same economic characteristics in that common units and shares of the company's common stock share equally in the total net income or loss distributions of the Operating Partnership. American Assets Trust, Inc. is the Operating Partnership’s general partner and is responsible for the management of the Operating Partnership’s business. As the general partner of the Operating Partnership, the company effectively controls the ability to issue common stock of American Assets Trust, Inc. upon a limited partner’s notice of redemption. Investors who own common units have the right to cause the Operating Partnership to redeem any or all of their common units for cash equal to the then-current market value of one share of the company's common stock, or, at the company's election, shares of the company's common stock on a one-for-one basis. In addition, American Assets Trust, Inc. has generally acquired common units upon a limited partner’s notice of redemption in exchange for shares of the company's common stock. The redemption provisions of common units owned by limited partners that permit the Operating Partnership to settle in either cash or common stock at the option of the company are further evaluated in accordance with applicable accounting guidance to determine whether temporary or permanent equity classification on the balance sheet is appropriate. The Operating Partnership evaluated this guidance, including the requirement to settle in unregistered shares, and determined that these common units meet the requirements to qualify for presentation as permanent equity. During the years ended December 31, 2017, 2016 and 2015, approximately 693,842, 10,694 and 5,741, respectively, common units were converted into shares of the company's common stock. |

| EQUITY OF AMERICAN ASSETS TRUST, INC. | EQUITY OF AMERICAN ASSETS TRUST, INC. Stockholders' Equity On May 6, 2013, we entered into an at-the-market (“ATM”) equity program with four sales agents pursuant to which we may, from time to time, offer and sell shares of our common stock having an aggregate offering price of up to $150.0 million. We completed $150.0 million of issuances under such ATM program on May 21, 2015. On May 27, 2015, 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 sales 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. For the year ended December 31, 2017, we issued 700,000 shares of common stock through the ATM equity program at a weighted average price per share of $43.46 for gross proceeds of $30.4 million and paid $0.3 million in sales agent compensation and $0.25 million in additional offering expenses related to the sales of these shares of common stock. As of December 31, 2017, we had the capacity to issue up to an additional $176.2 million in shares of our common stock under our active 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. We have no obligation to sell the remaining shares available for sale under the active ATM equity program. On March 9, 2015, we entered into a common stock purchase agreement (the “Purchase Agreement”) with Explorer Insurance Company, a California corporation ("EIC"), an entity owned and controlled by Ernest Rady, our Chairman, President and Chief Executive Officer. The Purchase Agreement provided for the sale by us to EIC, in a private placement, of 200,000 shares of our common stock at a purchase price of $40.54 per share, resulting in gross proceeds to us of approximately $8.1 million. The price per share paid by EIC was equal to the closing price of a share of our common stock on the New York Stock Exchange on the date of the Purchase Agreement. These shares were registered on March 27, 2015 by virtue of our filing of a prospectus supplement to our universal shelf registration statement on Form S-3 filed on February 6, 2015. Preferred Stock Authorized Shares We have been authorized to issue 10,000,000 shares of preferred stock with a par value of $0.01, of which no shares were outstanding at December 31, 2017. Upon issuance, our board of directors has the ability to define the terms of the preferred shares, including voting rights, liquidation preferences, conversion and redemption provisions and dividend rates. Dividends The following table lists the dividends declared and paid on our shares of common stock and Noncontrolling Common Units for the years ended December 31, 2017, 2016 and 2015:
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 loss on extinguishment of debt, revenue recognition and compensation expense and in the basis of depreciable assets and estimated useful lives used to compute depreciation. A summary of the income tax status of dividends per share paid is as follows:
Stock-Based Compensation The company has established the 2011 Equity Incentive Award Plan (the "2011 Plan"), which provides for grants to directors, employees and consultants of the company and the Operating Partnership of stock options, restricted stock, dividend equivalents, stock payments, performance shares, LTIP units, stock appreciation rights and other incentive awards. An aggregate of 4,054,411 shares of our common stock are authorized for issuance under awards granted pursuant to the 2011 Plan, and as of December 31, 2017, 2,800,299 shares of common stock remain available for future issuance. The following shares of restricted common stock have been issued as of December 31, 2017:
For the performance-based stock awards, the fair value of the awards was estimated using a Monte Carlo Simulation model. Our stock price, along with the stock prices of the group of peer REITs, is assumed to follow the Multivariate Geometric Brownian Motion Process. Multivariate Geometric Brownian Motion is a common assumption when modeling in financial markets, as it allows the modeled quantity (in this case, the stock price) to vary randomly from its current value and take any value greater than zero. The volatilities of the returns on the stock price of the company and the group REITs were estimated based on a three year look-back period. The expected growth rate of the stock prices over the “derived service period” of the employee is determined with consideration of the risk free rate as of the grant date. For the restricted stock grants that are time-vesting, we estimate the stock compensation expense based on the fair value of the stock at the grant date. The following table summarizes the activity of non-vested restricted stock awards during the year ended December 31, 2017:
We recognize noncash compensation expense ratably over the vesting period, and accordingly, we recognized $4.7 million, $2.4 million and $2.9 million in noncash compensation expense for the years ended December 31, 2017, 2016 and 2015, respectively, each of which is included in general and administrative expense on the statement of income. Unrecognized compensation expense was $4.0 million at December 31, 2017, which will be recognized over a weighted-average period of 1.6 years. 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. For the years ended December 31, 2017, 2016 and 2015, we had a weighted average of approximately 230,602 shares, 176,408 shares and 184,545 unvested shares outstanding, respectively, which are considered participating securities. Therefore, we have allocated our earnings for basic and diluted EPS between common shares and unvested shares. Diluted EPS is calculated by dividing the net income attributable 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 year ended December 31, 2017, 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. Earnings Per Unit of the Operating Partnership Basic earnings (loss) per unit (“EPU”) of the Operating Partnership is computed by dividing income (loss) 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 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 (losses). The calculation of diluted earnings per unit for the year ended December 31, 2017, 2016 and 2015 does not include 230,602 units, 176,408 units, and 184,545 unvested weighted average Operating Partnership units, respectively, as these equity securities are either considered contingently issuable or the effect of including these equity securities was anti-dilutive. 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 taxable year ending December 31, 2011. 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 liability is included in our consolidated balance sheets of $0.1 million and $0.3 million as of December 31, 2017 and 2016, respectively, in relation to real estate asset basis differences and prepaid expenses for our TRS. The income tax provision included in other income (expense) on the consolidated statement of income is as follows (in thousands):

| Commitments and Contingencies Disclosure [Abstract] | ||||||||||||||||||||||||||||||||||||||||||||||||||
| COMMITMENTS AND CONTINGENCIES | COMMITMENTS AND CONTINGENCIES Legal We are sometimes involved in various disputes, lawsuits, warranty claims, environmental 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 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 At The Landmark at One Market, we lease, as lessee, a building adjacent to The Landmark under an operating lease effective through June 30, 2021, which we have the option to extend until 2031 by way of two five-year extension options. At Waikiki Beach Walk, we sublease a portion of the building of which Quiksilver is currently in possession, under an operating lease effective through December 31, 2021. Current minimum annual payments under the leases are as follows, as of December 31, 2017 (in thousands):
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 calendar 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. Pursuant to the terms of the hotel management agreement, if the agreement is terminated in certain instances, including upon a transfer by us of the hotel or upon a default by us under the hotel management agreement, we would be required to pay a cancellation fee calculated by multiplying (1) the management fees for the previous 12 months by (2) (a) eight, if the agreement is terminated in the first 11 years of its term, or (b) four, three, two or one, if the agreement is terminated in the twelfth, thirteenth, fourteenth or fifteenth year, respectively, of its term. The hotel management agreement may not be terminated by us or by Outrigger without cause. 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 Suites 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 4.0% of the hotel's gross room revenue through December 2021 and 5.0% of the hotel's gross room revenue thereafter, 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 $7.5 million based on operating performance through December 31, 2017. Our Del Monte Center property has ongoing environmental remediation related to ground water contamination. The environmental issue existed at purchase and is currently in the final stages of remediation. The final stages of the remediation will include routine, long term ground monitoring by the appropriate regulatory agency over the next five to seven years. The work performed is financed through an escrow account funded by the seller upon our purchase of the 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 costing more than the remaining escrow funds, we could 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. As of December 31, 2017, the company accrued approximately $6.6 million for transfer taxes in connection with its Offering. The company believes that it has filed all necessary forms with the requisite taxing authorities. Concentrations of Credit Risk Our properties are located in Southern California, Northern California, Hawaii, Oregon, Texas and Washington. The ability of the tenants to honor the terms of their respective leases is dependent upon the economic, regulatory and social factors affecting the markets in which the tenants operate. Thirteen of our consolidated properties, representing 31.0% of our total revenue for the year ended December 31, 2017, are located in Southern California, which exposes us to greater economic risks than if we owned a more geographically diverse portfolio. Our mixed-use property located in Honolulu, Hawaii accounted for 19.6% of total revenues for the year ended December 31, 2017. Tenants in the retail industry accounted for 33.0% and 34.2% of total revenues for the years December 31, 2017 and 2016, respectively. 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. Two retail properties, Alamo Quarry Market and Waikele Center, accounted for 13.2% and 14.4% of total revenues for the years ended December 31, 2017 and 2016, respectively. Tenants in the office industry accounted for 33.6% and 35.0% of total revenues for the years December 31, 2017 and 2016, respectively. 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. For the years ended December 31, 2017 and 2016, no tenant accounted for more than 10.0% of our total rental revenue. At December 31, 2017, salesforce.com, inc. at The Landmark at One Market accounted for 7.9% of total annualized base rent. Three other tenants (Autodesk, Inc., Kmart, and Lowe's) comprise 9.7% of our total annualized base rent at December 31, 2017, in the aggregate. No other tenants represent greater than 2.0% of our total annualized base rent. Total annualized base rent used for the percentage calculations includes the annualized base rent as of December 31, 2017 for our office properties, retail properties and the retail portion of our mixed-use property. |

Our multifamily properties are located in Southern California, and we had approximately 1,844 leases with residential tenants at December 31, 2017, excluding Santa Fe Park RV Resort. 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 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 and also may include percentage rents based on the tenant's level of sales achieved. Leases on apartments generally range from seven 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. As of December 31, 2017, 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):

| RELATED PARTY TRANSACTIONS | RELATED PARTY TRANSACTIONS At Torrey Reserve Campus, we previously leased space to ICW, an entity owned and controlled by Ernest Rady. Rental revenue recognized on the leases of $0.1 million, $2.2 million and $2.2 million for the years ended December 31, 2017, 2016 and 2015, respectively, is included in rental income. Additionally, on July 1, 2014, we entered into a workers' compensation insurance policy with ICW. The policy premium was approximately $0.4 million for the period July 1, 2014 through July 1, 2015. We renewed this policy with ICW on July 1, 2015 and the premium was approximately $0.2 million for the period July 1, 2015 through July 1, 2016. We renewed this policy with ICW on July 1, 2016 and the premium was approximately $0.2 million for the period July 1, 2016 through July 1, 2017. We renewed this policy with ICW on June 30, 2017 and the premium is approximately $0.2 million for the period July 1, 2017 through July 1, 2018. At Torrey Reserve Campus, we lease space to American Assets, Inc., an entity owned and controlled by Ernest Rady. Rental revenue recognized on the lease of $0.1 million for the year ended December 31, 2017 is included in rental income. On occasion, the company utilizes aircraft services provided by AAI Aviation, Inc. ("AAIA"), an entity owned and controlled by Ernest Rady. For the years ending December 31, 2017, 2016 and 2015, we incurred approximately $0.1 million, $0.2 million and $0.2 million, respectively, of expenses 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. On March 9, 2015, we entered into a Common Stock Purchase Agreement with EIC, an entity owned and controlled by Ernest Rady. The Common Stock Purchase Agreement provided for the sale by us to EIC, in a private placement, of 200,000 shares of common stock at a price of $40.54 per share, resulting in gross proceeds to us of approximately $8.1 million. The price per share paid by EIC was equal to the closing price of a share of our common stock on the New York Stock Exchange on the date of the Common Stock Purchase Agreement. As of December 31, 2017, Mr. Rady and his affiliates owned approximately 12.2% of our outstanding common stock and 23.1% of our outstanding common units, which together represent an approximate 35.2% beneficial interest in our company on a fully diluted basis. 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 $1.0 million, $0.9 million and $1.0 million were made for the years ended December 31, 2017, 2016 and 2015, respectively, and included in rental expenses on the statements of income. |

| SEGMENT REPORTING | SEGMENT REPORTING Segment information is prepared on the same basis that our management reviews information for operational decision-making purposes. We review operating and financial information for each property on an individual basis and therefore, each property represents an individual operating segment. However, we have aggregated our properties into reportable segments as the properties share similar long-term economic characteristics and have other similarities including the fact that they are operated using consistent business strategies. We operate in four business segments: the acquisition, redevelopment, ownership and management of retail real estate, office real estate, multifamily real estate and mixed-use real estate. The products for our retail segment primarily include rental of retail space and other tenant services, including tenant reimbursements, parking and storage space rental. The products for our office segment primarily include rental of office space and other tenant services, including tenant reimbursements, parking and storage space rental. The products for our multifamily segment include rental of apartments and other tenant services. The products of our mixed-use segment include rental of retail space and other tenant services, including tenant reimbursements, parking and storage space rental and operation of a 369-room all-suite hotel. 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. The following table represents operating activity within our reportable segments (in thousands):
The following table is a reconciliation of segment profit to net income attributable to stockholders (in thousands):

The Second Amended and Restated Credit Facility has an accordion feature that may allow us to increase the availability thereunder up to an additional $350 million, subject to meeting specified requirements and obtaining additional commitments from lenders. Borrowings under the Second Amended and Restated Credit Agreement initially bear interest at floating rates equal to, at our option, either (1) LIBOR, plus a spread which ranges from (a) 1.05% to 1.50% (with respect to the Revolver Loan) and (b) 1.30% to 1.90% (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 or (c) LIBOR plus 100 bps, plus a spread which ranges from (i) 0.10% to 0.50% (with respect to the Revolver Loan) and (ii) 0.30% to 0.90% (with respect to Term Loan A), in each case based on our consolidated leverage ratio. The foregoing rates are more favorable than previously contained in the Prior Credit Agreement in place as of December 31, 2017. The Revolver Loan initially matures on January 9, 2022, subject to our option to extend the Revolver Loan up to two times, with each such extension for a six-month period. The Term Loan A matures on January 9, 2019. The foregoing extension options are exercisable by us subject to the satisfaction of certain conditions. Third Amendment to Term Loan Agreement On January 9, 2018, we entered into the Third Amendment to the Term Loan Agreement, which maintains the seven-year $150 million unsecured term loan (Term Loan B and Term Loan C) to the Operating Partnership that matures on March 1, 2023. Effective as of March 1, 2018, borrowings under the Term Loan Agreement with respect to the $150mm Term Loan bear interest at floating rates equal to, at the Operating Partnership’s option, either (1) LIBOR, plus a spread which ranges from 1.20% to 1.70% based on the Operating Partnership’s consolidated leverage ratio, or (2) a base rate equal to the highest of (a) 0%, (b) the prime rate, (c) the federal funds rate plus 50 bps or (d) the Eurodollar rate plus 100 bps, in each case plus a spread which ranges from 0.70% to 1.35% based on the Operating Partnership’s consolidated leverage ratio. The foregoing rates are intended to be more favorable than previously contained in the Term Loan Agreement. Additionally, the Operating Partnership may elect for borrowings to bear interest based on a ratings-based pricing grid as per the Operating Partnership’s then-applicable investment grade debt ratings under the terms set forth in the Term Loan Agreement. |

| 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 (the “Offering”) and the related acquisition on January 19, 2011 of certain assets of a combination of entities whose assets included entities owned and/or controlled by Ernest S. Rady and his affiliates, including the Rady Trust, which in turn owned (1) controlling interests in entities owning 17 properties and the property management business of American Assets, Inc. and (2) noncontrolling interests in entities owning four properties. 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 REIT subsidiary. 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 vertically integrated and self-administered REIT with 194 employees providing substantial in-house expertise in asset management, property management, property development, leasing, tenant improvement construction, acquisitions, repositioning, redevelopment and financing. Any reference to the number of properties or units, square footage or acres, employees; or references to beneficial ownership interests, are unaudited and outside the scope of our independent registered public accounting firm's audit of our financial statements in accordance with the standards of the United States Public Company Accounting Oversight Board. As of December 31, 2017, we owned or had a controlling interest in 26 office, retail, multifamily and mixed-use operating properties, the operations of which we consolidate. Additionally, as of December 31, 2017, we owned land at four of our properties that we classify as held for development and 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. All significant intercompany transactions and balances are eliminated in consolidation. |

| Use of Estimates | Use of Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America, referred to as “GAAP,” requires management 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 management's best judgment, after considering past, current and expected events and economic conditions. Actual results could differ from these estimates. |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Consolidated Statements of Cash Flows-Supplemental Disclosures | Consolidated Statements of Cash Flows-Supplemental Disclosures The following table provides supplemental disclosures related to the Consolidated Statements of Cash Flows (in thousands):
|
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| 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. When we determine that we are the owner of tenant improvements and the tenant has reimbursed us for a portion or all of the tenant improvement costs, we consider the amount paid to be additional rent, which is recognized on a straight-line basis over the term of the related lease. For first generation tenants, in instances in which we fund tenant improvements and the improvements are deemed to be owned by us, revenue recognition will commence when the improvements are substantially completed and possession or control of the space is turned over to the tenant. When we determine that the tenant is the owner of tenant improvements, tenant allowances are recorded as lease incentives and we commence revenue recognition and lease incentive amortization when possession or control of the space is turned over to the tenant for tenant work to begin. Percentage rents, which represent additional rents based upon the level of sales achieved by certain tenants, are recognized at the end of the lease year or earlier if we have determined the required sales level is achieved and the percentage rents are collectible. Real estate tax and other cost reimbursements are recognized on an accrual basis over the periods in which the related expenditures are incurred. Other property income includes parking income, general excise tax billed to tenants and fees charged to tenants at our multifamily properties. Other property income is recognized when earned. We recognize general excise tax gross, with the amounts billed to tenants and customers recorded in other property income and the related taxes paid as rental expense. The general excise tax included in other income was $3.7 million, $3.8 million and $3.7 million for the years ended December 31, 2017, 2016 and 2015, respectively. For a tenant to terminate its lease agreement prior to the end of the agreed term, we may require that they pay a fee to cancel the lease agreement. Lease termination fees for which the tenant has relinquished control of the space are generally recognized on the termination date. When a lease is terminated early but the tenant continues to control the space under a modified lease agreement, the lease termination fee is generally recognized evenly over the remaining term of the modified lease agreement. We recognize revenue on the hotel portion of our mixed-use property from the rental of hotel rooms and guest services when the rooms are occupied and services have been provided. Food and beverage sales are recognized when the customer has been served or at the time the transaction occurs. Revenue from room rental is included in rental revenue on the statement of income. Revenue from other sales and services provided is included in other property income on the statement of income. We make estimates of the collectability of our accounts receivable related to minimum rents, straight-line rents, expense reimbursements and other revenue. Accounts receivable and deferred rent receivable are carried net of this allowance for doubtful accounts. We generally do not require collateral or other security from our tenants, other than letters of credit or security deposits. Our determination as to the collectability of accounts receivable and correspondingly, the adequacy of this allowance, is based primarily upon evaluations of individual receivables, current economic conditions, historical experience and other relevant factors. The allowance for doubtful accounts is increased or decreased through bad debt expense. In some cases, primarily relating to straight-line rents, the collection of these amounts extends beyond one year. Our experience relative to unbilled straight-line rents is that a portion of the amounts otherwise recognizable as revenue is never billed to or collected from tenants due to early lease terminations, lease modifications, bankruptcies and other factors. Accordingly, the extended collection period for straight-line rents along with our evaluation of tenant credit risk may result in the nonrecognition of a portion of straight-line rental income until the collection of such income is reasonably assured. If our evaluation of tenant credit risk changes indicating more straight-line revenue is reasonably collectible than previously estimated and realized, the additional straight-line rental income is recognized as revenue. If our evaluation of tenant credit risk changes indicating a portion of realized straight-line rental income is no longer collectible, a reserve and bad debt expense is recorded. At December 31, 2017 and December 31, 2016, our allowance for doubtful accounts was $0.4 million and $0.4 million, respectively. Our allowance for deferred rent receivables at December 31, 2017 and December 31, 2016 was $1.4 million and $1.3 million, respectively. Total bad debt expense was $0.8 million, $0.8 million and $0.4 million for the years ended December 31, 2017, 2016 and 2015, respectively. We recognize gains on sales of properties upon the closing of the transaction with the purchaser. Gains on properties sold are recognized using the full accrual method when (1) the collectability of the sales price is reasonably assured, (2) we are not obligated to perform significant activities after the sale, (3) the initial investment from the buyer is sufficient and (4) other profit recognition criteria have been satisfied. Gains on sales of properties may be deferred in whole or in part until the requirements for gain recognition have been met. |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Real Estate | Real Estate Land, buildings and improvements are recorded at cost. Depreciation is computed using the straight-line method. Estimated useful lives range generally from 30 years to a maximum of 40 years on buildings and major improvements. Minor improvements, furniture and equipment are capitalized and depreciated over useful lives ranging from 3 years to 15 years. Maintenance and repairs that do not improve or extend the useful lives of the related assets are charged to operations as incurred. Tenant improvements are capitalized and depreciated over the life of the related lease or their estimated useful life, whichever is shorter. If a tenant vacates its space prior to the contractual termination of its lease, the undepreciated balance of any tenant improvements are written off if they are replaced or have no future value. For the years ended December 31, 2017, 2016 and 2015, real estate depreciation expense was $70.2 million, $62.5 million and $54.2 million, respectively. Acquisitions of properties are accounted for in accordance with the authoritative accounting guidance on acquisitions and business combinations. Our methodology of allocating the cost of acquisitions to assets acquired and liabilities assumed is based on estimated fair values, replacement cost and appraised values. When we acquire operating real estate properties, the purchase price is allocated to land and buildings, intangibles such as in-place leases, and to current assets and liabilities acquired, if any. Such valuations include a consideration of the noncancelable terms of the respective leases as well as any applicable renewal periods. The fair values associated with below market renewal options are determined based on a review of several qualitative and quantitative factors on a lease-by-lease basis at acquisition to determine whether it is probable that the tenant would exercise its option to renew the lease agreement. These factors include: (1) the type of tenant in relation to the property it occupies, (2) the quality of the tenant, including the tenant's long term business prospects and (3) whether the fixed rate renewal option was sufficiently lower than the fair rental of the property at the date the option becomes exercisable such that it would appear to be reasonably assured that the tenant would exercise the option to renew. The value allocated to in-place leases is amortized over the related lease term and reflected as depreciation and amortization in the statement of income. The value of above and below market leases associated with the original noncancelable lease terms are amortized to rental income over the terms of the respective noncancelable lease periods and are reflected as either an increase (for below market leases) or a decrease (for above market leases) to rental income in the statement of income. The value of the leases associated with below market lease renewal options that are likely to be exercised are amortized to rental income over the respective renewal periods. If a tenant vacates its space prior to contractual termination of its lease or the lease is not renewed, the unamortized balance of any in-place lease value is written off to rental income and amortization expense. |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Capitalized Costs | Capitalized Costs We capitalize certain costs related to the development and redevelopment of real estate including pre-construction costs, real estate taxes, insurance and construction costs and salaries and related costs of personnel directly involved. Additionally, we capitalize interest costs related to development and significant redevelopment activities. Capitalization of these costs begins when the activities and related expenditures commence and cease when the project is substantially complete and ready for its intended use, at which time the project is placed in service and depreciation commences. Additionally, we make estimates as to the probability of certain development and redevelopment projects being completed. If we determine that the completion of development or redevelopment is no longer probable, we expense all capitalized costs which are not recoverable. |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Impairment of Long Lived Assets | Impairment of Long Lived Assets We review for impairment on a property by property basis whenever events or changes in circumstances indicate that the carrying value of a property may not be fully recoverable. Impairment is recognized on properties held for use when the expected undiscounted cash flows for a property are less than its carrying amount at which time the property is written-down to fair value. Properties held for sale are recorded at the lower of the carrying amount or the expected sales price less costs to sell. |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Financial Instruments | Financial Instruments The estimated fair values of financial instruments are determined using available market information and appropriate valuation methods. Considerable judgment is necessary to interpret market data and develop estimated fair values. The use of different market assumptions or estimation methods may have a material effect on the estimated fair value amounts. Accordingly, estimated fair values are not necessarily indicative of the amounts that could be realized in current market exchanges. |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Derivative Instruments | Derivative Instruments At times, we may use derivative instruments to manage exposure to variable interest rate risk. We may enter into interest rate swaps to manage our exposure to variable interest rate risk. If and when we enter into derivative instruments, we ensure that such instruments qualify as cash flow hedges and would not enter into derivative instruments for speculative purposes. Any interest rate swaps associated with our cash flow hedges are recorded at fair value on a recurring basis. We assess effectiveness of our cash flow hedges both at inception and on an ongoing basis. The effective portion of changes in fair value of the interest rate swaps associated with our cash flow hedges is recorded in accumulated other comprehensive income (loss) and is subsequently reclassified into interest expense as interest is incurred on the related variable rate debt. Our cash flow hedges become ineffective if critical terms of the hedging instrument and the debt instrument do not perfectly match such as notional amounts, settlement dates, reset dates, calculation period and LIBOR rate. In addition, we evaluate the default risk of the counterparty by monitoring the credit worthiness of the counterparty. When ineffectiveness exists, the ineffective portion of changes in fair value of the interest rate swaps associated with our cash flow hedges is recognized in earnings in the period affected. |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Cash and Cash Equivalents | Cash and Cash Equivalents We define cash and cash equivalents as cash on hand, demand deposits with financial institutions and short term liquid investments with an initial maturity of less than 3 months. Cash balances in individual banks may exceed the federally insured limit of $250,000 by the Federal Deposit Insurance Corporation (the "FDIC"). No losses have been experienced related to such accounts. |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Restricted Cash | Restricted Cash Restricted cash consists of amounts held by lenders to provide for future real estate tax expenditures, insurance expenditures and reserves for capital improvements. |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Other Assets | Other Assets Other assets consist primarily of lease costs, lease incentives, acquired in-place leases and acquired above market leases. Capitalized lease costs are direct costs incurred which were essential to originate a lease and would not have been incurred had the leasing transaction not taken place and include third party commissions related to obtaining a lease. Capitalized lease costs are amortized over the life of the related lease and included in depreciation and amortization expense on the statement of income. If a tenant vacates its space prior to the contractual termination of its lease, the unamortized balance of any lease costs are written off. We view these lease costs as part of the up-front initial investment we made in order to generate a long-term cash inflow. Therefore, we classify cash outflows for lease costs as an investing activity in our consolidated statements of cash flows. |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Variable Interest Entities | Variable Interest Entities Certain entities that do not have sufficient equity at risk for the entity to finance its activities without additional subordinated financial support from other parties or in which equity investors do not have the characteristics of a controlling financial interest qualify as variable interest entities (“VIEs”). VIEs are required to be consolidated by their primary beneficiary. The primary beneficiary of a VIE is the party that has a controlling interest in the VIE. Identifying the party with the controlling interest requires a focus on which entity has the power to direct the activities of the VIE that most significantly impact the VIE's economic performance and (1) the obligation to absorb the expected losses of the VIE or (2) the right to receive the benefits from the VIE. |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Stock-Based Compensation | Stock-Based Compensation We grant stock-based compensation awards to our employees and directors typically in the form of restricted shares of common stock, options to purchase common stock and/or shares of common stock. We measure stock-based compensation expense based on the fair value of the award on the grant date and recognize the expense ratably over the vesting period. |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Deferred Compensation | Deferred Compensation Our Operating Partnership has adopted the American Assets Trust Executive Deferral Plan V (“EDP V”) and the American Assets Trust Executive Deferral Plan VI (“EDP VI”). These plans were adopted by our Operating Partnership as successor plans to those deferred compensation plans maintained by American Assets Inc. ("AAI") in which certain employees of AAI, who were transferred to us in connection with the Offering (the “Transferred Participants”), participated prior to the Offering. EDP V and EDP VI contain substantially the same terms and conditions as these predecessor plans. AAI transferred to our Operating Partnership the Transferred Participants' account balances under the predecessor plans. These transferred account balances represent amounts deferred by the Transferred Participants prior to the Offering while they were employed by AAI. At the time eligible participants defer compensation, we record compensation cost and a corresponding deferred compensation plan liability, which is included in other liabilities and deferred credits on our consolidated balance sheets. This liability is adjusted to fair value at the end of each accounting period based on the performance of the benchmark funds selected by each participant, and the impact of adjusting the liability to fair value is recorded as an increase or decrease to compensation cost. |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Income Taxes | Income Taxes We elected to be taxed as a REIT under the Internal Revenue Code of 1986, as amended (the “Code”) commencing with the taxable year ending December 31, 2011. To maintain our qualification as a REIT, we are required to distribute at least 90% of our REIT taxable income to our stockholders and meet the various other requirements imposed by the Code relating to such matters as operating results, asset holdings, distribution levels and diversity of stock ownership. Provided we maintain our qualification for taxation 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. If we fail to maintain our qualification as a REIT in any taxable year, and are unable to avail ourselves of certain savings provisions set forth in the Code, all of our taxable income would be subject to regular U.S. federal income tax. We are subject to certain state and local income taxes. We, together with one of our subsidiaries, have elected to treat such subsidiary as a taxable REIT subsidiary (a “TRS”) for federal income tax purposes. Certain activities that we undertake must be conducted by a TRS, such as non-customary services for our tenants, and holding assets that we cannot hold directly. A TRS is subject to federal and state income taxes. |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Segment Information | Segment Information Segment information is prepared on the same basis that our management reviews information for operational decision-making purposes. We operate in four reportable segments: the acquisition, redevelopment, ownership and management of retail real estate, office real estate, multifamily real estate and mixed-use real estate. The products for our retail segment primarily include rental of retail space and other tenant services, including tenant reimbursements, parking and storage space rental. The products for our office segment primarily include rental of office space and other tenant services, including tenant reimbursements, parking and storage space rental. The products for our multifamily segment include rental of apartments and other tenant services. The products of our mixed-use segment include rental of retail space and other tenant services, including tenant reimbursements, parking and storage space rental and operation of a 369-room all-suite hotel. |

| Recent Accounting Pronouncements | Recent Accounting Pronouncements In August 2017, the FASB issued Accounting Standards Update (“ASU”) 2017-12, Derivatives and Hedging: Targeted Improvements to Accounting for Hedging Activities. The pronouncement was issued to simplify the on-going assessment of hedge effectiveness and increase transparency related to hedge accounting. The pronouncement is effective for fiscal years, and for interim periods within those fiscal years, beginning after December 15, 2018, with early adoption permitted. The company early adopted the provisions of ASU No. 2017-12 effective October 1, 2017 using the modified retrospective approach. The company determined there is no impact to the company’s historical results as a result of adoption of the new standard and therefore no adjustment to retained earnings from application of the ASU. In January 2017, the FASB issued ASU 2017-1, Business Combinations: Clarifying the Definition of a Business. The pronouncement changes the definition of a business to assist entities with evaluating when a set of transferred assets and activities is a business. The pronouncement requires an entity to evaluate if substantially all of the fair value of the gross assets acquired is concentrated in a single identifiable asset or a group of similar identifiable assets; if so, the set of transferred assets and activities is not a business. The pronouncement is effective for fiscal years, and for interim periods within those fiscal years, beginning after December 15, 2018, with early adoption permitted. The company early adopted this ASU effective January 1, 2017. For the period from January 1, 2017 through December 31, 2017, the company acquired three properties for which we concluded that substantially all of the fair value of the assets acquired were concentrated in a single identifiable asset and that the assets therefore did not meet the definition of a business under ASU 2017-01. Acquisition transaction costs associated with these property acquisitions were approximately $0.2 million and were capitalized to real estate investments. In November 2016, the FASB issued ASU 2016-18, Restricted Cash. This pronouncement requires companies to include restricted cash and restricted cash equivalents with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flows. The pronouncement also requires a disclosure of a reconciliation between the statement of financial position and the statement of cash flows when the balance sheet includes more than one line item for cash, cash equivalents, restricted cash, and restricted cash equivalents. Entities with material restricted cash and restricted cash equivalents balances will be required to disclose the nature of the restrictions. The ASU is effective for reporting periods beginning after December 15, 2017, with early adoption permitted, and will be applied retrospectively to all periods presented. The company adopted this ASU effective December 31, 2017. The adoption of this ASU impacted the presentation of cash flows with inclusion of restricted cash flows for each of the presented periods. As of December 31, 2017 and December 31, 2016 , we had $9.3 million and $10.0 million of restricted cash, respectively, on our consolidated balance sheets. In March 2016, the FASB issued ASU 2016-09, Improvements to Employee Share-Based Payment Accounting, which simplifies several aspects of the accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. ASU 2016-09 is effective for fiscal years beginning after December 15, 2016, and interim periods within those fiscal years. The company adopted this ASU effective January 1, 2017 and the adoption did not have a material impact on our consolidated financial statements. In February 2016, the FASB issued ASU No. 2016-2, Leases. This pronouncement is expected to result in the recognition of a right-to-use asset and related liability to account for future obligations under ground lease agreements for which the Company is the lessee. In addition, this pronouncement will require that lessees and lessors capitalize, as initial direct costs, only those costs that are incurred due to the execution of a lease. As of December 31, 2017, the remaining contractual payments under lease agreements for which the company is the lessee aggregated approximately $38.3 million. As a lessor, under current accounting standards, the company recognizes rental revenue from our operating leases on a straight-line basis over the respective lease terms. The company commences recognition of rental revenue at the date the property is ready for its intended use and the tenant takes possession of or controls the physical use of the property. Under current accounting standards, tenant recoveries related to payments of real estate taxes, insurance, utilities, repairs and maintenance, common area expenses, and other operating expenses are considered lease components. The company recognizes these tenant recoveries as revenue when services are rendered in an amount equal to the related operating expenses incurred that are recoverable under the terms of the applicable lease. Under this pronouncement, each lease agreement will be evaluated to identify the lease components and nonlease components at lease inception. The total consideration in the lease agreement will be allocated to the lease and nonlease components based on their relative standalone selling prices. Lessors will continue to recognize the lease revenue component using an approach that is substantially equivalent to existing guidance for operating leases (straight-line basis). In January 2018, the FASB issued a proposed amendment to the lease ASU that would allow lessors to elect, as a practical expedient, not to allocate the total consideration to lease and nonlease components based on their relative standalone selling prices. If adopted, this practical expedient will allow lessors to elect a combined single lease component presentation if (i) the timing and pattern of the revenue recognition of the combined single lease component is the same, and (ii) the related lease component and, the combined single lease component would be classified as an operating lease. The pronouncement is effective for fiscal years, and for interim periods within those fiscal years, beginning after December 15, 2018, with early adoption permitted. The company plans to adopt the provisions of ASU No. 2016-2 effective January 1, 2019 using the modified retrospective approach. The company continues to evaluate the impact this pronouncement will have on the company’s consolidated financial statements. In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers. The pronouncement was issued to clarify the principles for recognizing revenue and to develop a common revenue standard and disclosure requirements for U.S. GAAP and International Financial Reporting Standards. The pronouncement is effective for reporting periods beginning after December 15, 2017. The company will adopt the provisions of the ASU effective January 1, 2018 using the modified retrospective approach. As discussed above, leases are specifically excluded from this and will be governed by the applicable lease codification; however, this update may have implications on certain variable payment terms included in lease agreements. Upon adoption of the new lease ASU in 2019, we may be required to classify our tenant recoveries into lease and nonlease components, whereby the nonlease components would be subject to the revenue recognition ASU, pending the resolution of the proposed amendment issued by the FASB in January 2018. Property services categorized as nonlease components that are reimbursed by our tenants may need to be presented on a net basis if it is determined that we hold an agent arrangement. The Company evaluated the revenue recognition for all contracts within this scope under existing accounting standards and under the new revenue recognition ASU and confirmed that there were no differences in the amounts recognized or the pattern of recognition. This evaluation included revenues from the hotel portion of our mixed-use property, parking income and excise taxes charged to customers. Therefore, the adoption of this ASU did not result in an adjustment to the Company’s retained earnings on January 1, 2018. |
