Summary of Significant Accounting Policies and Recent Accounting Pronouncements | 2. Summary of Significant Accounting Policies and Recent Accounting Pronouncements Principles of Consolidation. Our consolidated financial statements include our accounts and the accounts of other subsidiaries and joint ventures (including partnerships and limited liability companies) over which we have control. All intercompany transactions, balances, and profits have been eliminated in consolidation. Investments acquired or created are evaluated based on the accounting guidance relating to variable interest entities ("VIEs"), which requires the consolidation of VIEs in which we are considered to be the primary beneficiary. If the investment is determined not to be a VIE, then the investment is evaluated for consolidation primarily using a voting interest model. In determining if we have a controlling financial interest, we consider factors such as ownership interests, authority to make decisions, kick-out rights, and participating rights. As of December 31, 2024, two of our consolidated operating partnerships are VIEs. We are considered the primary beneficiary of both consolidated operating partnerships and therefore consolidate these operating partnerships. As of December 31, 2024, we held approximately 93% and 95% of the outstanding common limited partnership units and the sole 1% general partnership interest in each of these consolidated operating partnerships. Acquisitions of Real Estate. Upon the acquisition of real estate, we determine the fair value of tangible and intangible assets, which includes land, buildings (as-if-vacant), furniture and fixtures, the value of in-place leases, including above and below market leases, and acquired liabilities. In estimating these values, we apply methods similar to those used by independent appraisers of income-producing property. Estimates of fair value of acquired debt are based upon interest rates available for the issuance of debt with similar terms and remaining maturities. Depreciation is computed on a straight-line basis over the remaining useful lives of the related tangible assets. The value of in-place leases and above or below market leases is amortized over the estimated average remaining life of leases in place at the time of acquisition; the net carrying value of in-place leases are included in other assets, net, and the net carrying value of above or below market leases are included in other liabilities, net in our consolidated balance sheets. We did not recognize amortization expense related to in-place leases or revenue related to net below-market leases during the years ended December 31, 2024 and 2023. We recognized amortization expense related to in-place leases of approximately $50.3 million and recognized revenue related to net below-market leases of approximately $8.6 million for the year ended December 31, 2022. During the year ended December 31, 2022, the weighted average amortization period for in-place leases was approximately eight months, and the weighted average amortization periods for net below-market leases was approximately seven months. Asset Impairment. Long-lived assets are reviewed for impairment annually or whenever events or changes in circumstances indicate the carrying amount of an asset may not be recoverable. Impairment may exist if estimated future undiscounted cash flows associated with long-lived assets are not sufficient to recover the carrying value of such assets. We consider projected future undiscounted cash flows, trends, strategic decisions regarding future development plans, and other factors in our assessment of whether impairment conditions exist. While we believe our estimates of future cash flows are reasonable, different assumptions regarding a number of factors, including market rents, economic conditions, and occupancies, could significantly affect these estimates. When impairment exists, the long-lived asset is adjusted to its fair value. In estimating fair value, management uses appraisals, comparable sales, management estimates, and discounted cash flow calculations which utilize inputs from a marketplace participant’s perspective. In addition, we evaluate our equity investments in joint ventures, if any, and if we believe there is an other than temporary decline in market value of our investment below our carrying value, we will record an impairment charge. The value of our properties under development depends on market conditions, including estimates of the project start date, projected construction costs, and demand for multifamily communities. We have reviewed market trends and other marketplace information and incorporated this information as well as our current outlook into the assumptions we use in our impairment analyses. Due to the judgment and assumptions applied in the impairment analyses, it is possible actual results could differ substantially from those estimated. We believe the carrying value of our operating real estate assets, properties under development, and land is currently recoverable. However, if market conditions deteriorate or if changes in our development strategy significantly affect any key assumptions used in our fair value estimates, we may need to take material charges in future periods for impairments related to existing assets. Any such non-cash charges could have an adverse effect on our consolidated financial position and results of operations. Cash and Cash Equivalents. All cash and investments in money market accounts and other highly liquid securities with a maturity of three months or less at the date of purchase are considered to be cash and cash equivalents. We maintain the majority of our cash and cash equivalents at major financial institutions in the United States and deposits with these financial institutions may exceed the amount of insurance provided on such deposits; however, we regularly monitor the financial stability of these financial institutions and believe we are not currently exposed to any significant default risk with respect to these deposits. Cost Capitalization. Real estate assets are carried at cost plus capitalized carrying charges. Carrying charges are primarily interest and real estate taxes which are capitalized as part of properties under development. Capitalized interest is generally based on the weighted average interest rate of our unsecured debt. Expenditures directly related to the development and improvement of real estate assets are capitalized at cost as land and buildings and improvements. Indirect development costs, including salaries and benefits and other related costs directly attributable to the development of properties, are also capitalized. We begin capitalizing development, construction, and carrying costs when the development of the future real estate asset is probable and activities necessary to prepare the underlying real estate for its intended use have been initiated. All construction and certain carrying costs are capitalized and reported in the balance sheet as properties under development until the apartment homes are substantially completed. As apartment homes within development properties are completed, the total capitalized development cost of each apartment home is transferred from properties under development including land to buildings and improvements. As discussed above, carrying charges are principally interest and real estate taxes capitalized as part of properties under development. Capitalized interest was approximately $17.9 million, $20.2 million, and $18.1 million for the years ended December 31, 2024, 2023, and 2022, respectively. Capitalized real estate taxes were approximately $3.2 million, $3.4 million, and $4.2 million for the years ended December 31, 2024, 2023, and 2022, respectively. Where possible, we stage our construction to allow leasing and occupancy during the construction period, which we believe minimizes the duration of the lease-up period following completion of construction. Our accounting policy related to properties in the development and leasing phase is to expense all operating costs associated with completed apartment homes. We capitalize renovation and improvement costs we believe extend the economic lives of depreciable property. Capital expenditures subsequent to initial construction are capitalized and depreciated over their estimated useful lives. Depreciation and amortization is computed over the expected useful lives of depreciable property on a straight-line basis with lives generally as follows:
| Estimated Useful Life
Buildings and improvements | 5-35 years
Furniture, fixtures, equipment and other | 3-20 years
Intangible assets/liabilities (in-place leases and below market leases) | underlying lease term
Derivative Financial Instruments. Derivative financial instruments are recorded in the consolidated balance sheets at fair value and presented on a gross basis for financial reporting purposes even when those instruments are subject to master netting arrangements and may otherwise qualify for net presentation. Accounting for changes in the fair value of derivatives depends on the intended use of the derivative, whether we have elected to designate a derivative in a hedging relationship and apply hedge accounting, and whether the hedging relationship has satisfied the criteria necessary to apply hedge accounting. Cash flows from derivatives and the related gains and losses are classified as cash flows from operating activities on the consolidated statements of cash flows. Cash Flow Hedges. For derivative instruments which are designated and qualify as a cash flow hedge, the derivative's gain or loss is reported as a component to other comprehensive income ("OCI") and recorded in accumulated other comprehensive income ("AOCI") on our consolidated balance sheets. The gain or loss is subsequently reclassified into net earnings when the hedged exposure affects net earnings, in the same line item as the underlying hedged item on our consolidated statements of income and comprehensive income. Cash flow hedges related to anticipated transactions are designated and documented at the inception of each hedge. Cash flows from hedging transactions are classified in the same categories as the cash flows from the respective hedged items. Fair Value Hedges. For derivative instruments which are designated and qualify as a fair value hedge, the changes in fair value of the derivative instrument and the offsetting changes in fair value of the underlying hedged item due to changes in the hedged risk are recorded to interest expense on our consolidated statements of earnings. Counterparty Credit Risk. Fair values of our derivatives can change significantly from period to period based on, among other factors, market movements and changes in our positions. We manage counterparty credit risk (the risk counterparties will default and not make payments to us according to the terms of our agreements) on an individual counterparty basis. Gains or losses on sales of real estate. The Company recognizes the sale, and associated gain or loss from the disposition, when the criteria for derecognition of an asset is met, including when a contract exists and the buyer obtained control of the nonfinancial asset sold, in accordance with accounting principles generally accepted in the United States of America ("GAAP"). Fair Value. For financial assets and liabilities recorded at fair value on a recurring or non-recurring basis, fair value is the price we would receive to sell an asset, or pay to transfer a liability, in an orderly transaction with a market participant at the measurement date. In the absence of such data, fair value is estimated using internal information consistent with what market participants would use in a hypothetical transaction. In determining fair value, observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect our market assumptions; preference is given to observable inputs. These two types of inputs create the following fair value hierarchy: •Level 1: Quoted prices for identical instruments in active markets. •Level 2: Quoted prices for similar instruments in active markets; quoted prices for identical or similar instruments in markets that are not active; and model-derived valuations whose inputs are observable or whose significant value drivers are observable. •Level 3: Significant inputs to the valuation model are unobservable. Recurring Fair Value Measurements. The following describes the valuation methodologies we use to measure different financial instruments at fair value on a recurring basis: Derivative Financial Instruments. The estimated fair values of derivative financial instruments are valued using widely accepted valuation techniques including discounted cash flow analysis on the expected cash flows of each derivative. This analysis reflects the contractual terms of the derivatives, including the period to maturity, and uses observable market-based inputs, including interest rate curves and volatility. The fair values of interest rate swaps are estimated using the market-standard methodology of netting the discounted fixed cash payments and the discounted expected variable cash receipts. The variable cash receipts are based on an expectation of interest rates (forward curves) derived from observable market interest rate curves. In addition, credit valuation adjustments, which consider the impact of any credit enhancements to the contracts, are incorporated in the fair values to account for potential nonperformance risk, including our own nonperformance risk and the respective counterparty’s nonperformance risk. Although we have determined the majority of the inputs used to value our derivatives fall within Level 2 of the fair value hierarchy, the credit valuation adjustments associated with our derivatives utilize Level 3 inputs, such as estimates of current credit spreads, to evaluate the likelihood of default. However, we have assessed the significance of the impact of the credit valuation adjustments on the overall valuation of our derivative positions and have determined the credit valuation adjustments are not significant to the overall valuation of our derivatives. As a result, we have determined our derivative valuations in their entirety are classified in Level 2 of the fair value hierarchy. Deferred Compensation Plan Investments. The estimated fair values of investment securities classified as deferred compensation plan investments are based on quoted market prices utilizing public information for the same transactions. Our deferred compensation plan investments are recorded in other assets in our consolidated balance sheets. The inputs associated with the valuation of our recurring deferred compensation plan investments are included in Level 1 of the fair value hierarchy. Non-recurring Fair Value Measurements. Certain assets are measured at fair value on a non-recurring basis. These assets are not measured at fair value on an ongoing basis, but are subject to fair value adjustments in certain circumstances. These assets primarily include long-lived assets which are recorded at fair value when they are acquired, including the remeasurement of previously held ownership interests, using fair value methodologies described above at "Acquisitions of Real Estate," or if the long-lived assets are impaired using the fair value methodologies used to measure long-lived assets described above at "Asset Impairment." The inputs associated with the valuation of long-lived assets are generally included in Level 3 of the fair value hierarchy, unless a quoted price for a similar long-lived asset in an active market exists, at which time they are included in Level 2 of the fair value hierarchy. Financial Instrument Fair Value Disclosures. As of December 31, 2024 and 2023, the carrying values of cash and cash equivalents, accounts receivable, accounts payable, accrued expenses, and distributions payable represent fair value because of the short-term nature of these instruments. The carrying value of restricted cash approximates its fair value based on the nature of our assessment of the ability to recover these amounts. The carrying value of our notes receivable, which are included in other assets, net in our consolidated balance sheets, approximates their fair value. The estimated fair values are based on certain factors, such as market interest rates, terms of the note, and credit worthiness of the borrower. These financial instruments utilize Level 3 inputs. In calculating the fair value of our notes payable, interest rate, and spread assumptions reflect current credit worthiness and market conditions available for the issuance of notes payable with similar terms and remaining maturities. These financial instruments utilize Level 2 inputs. Income Recognition. The majority of our revenues are derived from real estate lease contracts which are accounted for pursuant to ASC 842, Leases, and presented as property revenues, and include rental revenue under contractual terms for other services provided to our customers. As a lessor, we made elections pursuant to ASC 842 to 1) not separate the lease and non-lease components by class of underlying assets and account for the combined components as a single component under certain conditions, and 2) exclude from lease revenues the sales taxes collected from lessees and certain lessor costs paid directly by the lessee. Our other revenue streams include fee and asset management income in accordance with other revenue guidance, ASC 606, Revenues from Contracts with Customers. A detail of our material revenue streams are discussed below: Property Revenue. We earn rental revenue from operating lease contracts for the use of dedicated spaces within owned assets, which is our only underlying asset class. We also earn revenues under contractual terms for other services considered non-lease components within a lease contract, primarily consisting of utility rebillings and other transactional fees. These amounts received under contractual terms for other services are charged to our residents and recognized monthly as earned. Any identified uncollectible amounts related to individual lease contracts are presented as an adjustment to property revenue. Any renewal options of real estate lease contracts are considered a new, separate contract and will be recognized at the time the option is exercised on a straight-line basis over the renewal period. As of December 31, 2024, our average residential lease term was approximately fourteen months with all other commercial leases averaging longer lease terms. We anticipate property revenue from existing leases as follows:
(in millions) |
Year ending December 31, | Operating Leases
2025 | $ | 871.6 |
2026 | 51.2 |
2027 | 3.3 |
2028 | 3.0 |
2029 | 2.6 |
Thereafter | 3.6 |
Total | $ | 935.3 |
Credit Risk. We believe there is no significant concentration of credit risk due to the number of residents, the types and diversity of submarkets in which our properties operate, and the collection terms. Insurance. Our primary lines of insurance coverage are property, general liability, health, workers compensation, and cybersecurity. We believe our insurance coverage adequately insures our properties against the risk of loss attributable to fire, earthquake, hurricane, tornado, flood, and other perils and adequately insures us against other risks. Losses are accrued based upon our estimates of the aggregate liability for claims incurred as well as using certain actuarial assumptions followed in the insurance industry and based on our experience. Other Assets, Net. Other assets in our consolidated financial statements include investments under deferred compensation plans, deferred financing costs, technology investments, non-real estate leasehold improvements and equipment, notes receivable, derivatives, operating lease right-of-use ("ROU") assets, prepaid expenses, and other miscellaneous receivables. Investments under deferred compensation plans are classified as trading securities and are adjusted to fair market value at period end. For a further discussion of our investments under deferred compensation plans, see Note 10. "Share-based Compensation and Benefit Plans." Deferred financing costs are related to our unsecured revolving credit facility, and are amortized no longer than the terms of the related facility on the straight-line method, which approximates the effective interest method. Corporate leasehold improvements and equipment includes expenditures related to renovation and construction of office space we lease. These leasehold improvements are depreciated using the straight-line method over the shorter of the expected useful lives or the lease terms which generally range from three to ten years. Investments. We hold equity interests in certain technology funds which are not accounted for using the equity method because we have virtually no influence over these entities and their fair values are not readily determinable. These investments are recorded using the measurement alternative in which our equity interests are recorded at cost, adjusted for impairments and observable price changes in orderly transactions for an identical or similar investment of the same issuer. At each reporting period, we reassess whether these investments continue to qualify for this measurement alternative. We had investments recorded at cost of approximately $16.6 million and $14.3 million at December 31, 2024 and 2023, respectively. These investments are included in other assets, net in our consolidated balance sheets and we did not record any impairments during the years ended December 31, 2024, 2023, or 2022 relating to these investments. Restricted Cash. Restricted cash consists of escrow deposits held by lenders for property taxes, insurance and replacement reserves, cash required to be segregated for the repayment of residents’ security deposits, and escrowed amounts related to our development and acquisition activities. Share-based Compensation. Compensation expense associated with share-based awards is recognized in our consolidated statements of income and comprehensive income using the grant-date fair values. Compensation cost for all share-based awards, including options, requires measurement at estimated fair value on the grant date and recognition of compensation expense over the requisite service period for awards expected to vest. The fair value of stock option grants is estimated using the Black-Scholes valuation model. Valuation models require the input of assumptions, including judgments to estimate the expected stock price volatility, expected life, and forfeiture rate. The compensation cost for share-based awards is based on the market value of the shares on the date of grant and is adjusted as actual forfeitures occur. Use of Estimates. In the application of GAAP, management is required to make estimates and assumptions which affect the reported amounts of assets and liabilities at the date of the financial statements, results of operations during the reporting periods, and related disclosures. Our more significant estimates include estimates supporting our impairment analysis related to the carrying values of our real estate assets. These estimates are based on historical experience and other assumptions believed to be reasonable under the circumstances. Future events rarely develop exactly as forecasted, and the best estimates routinely require adjustment. Recent Accounting Pronouncements: In November 2023, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2023-07 ("ASU 2023-07"), Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures which requires reportable segment disclosures of significant segment expenses provided to the chief operating decision makers ("CODMs"). The standard does not change the definition of a reportable segment, the method for determining segments, or the criteria for aggregating operating segments into reportable segments. We have adopted ASU 2023-07 in our 2024 Form 10-K, as disclosed in Note 14. "Reportable Segments", and this adoption did not have a material impact on our consolidated financial statements. In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures. ASU 2023-09 requires additional disclosures to enhance the transparency regarding income tax information through the use of a rate reconciliation table and disclosure of net taxes paid, detailed by federal, state, and foreign taxes and, if applicable, further detailed by specific jurisdictions if the amount exceeds a qualitative threshold. ASU 2023-09 is effective for annual periods beginning after December 15, 2024, and early adoption is permitted. This standard may be applied either on a prospective basis or on a retrospective basis. We expect to adopt ASU 2023-09 in our 2025 Form 10-K and expect the enhanced presentation of income tax disclosures will have no impact on our consolidated financial statements. In November 2024, the FASB issued ASU 2024-03, Disaggregation of Income Statement Expenses. ASU 2024-03 requires public entities to provide additional disclosures in the notes to the financial statements of certain expense categories which are included in expense line items disclosed on the face of the income statement. Specifically, an entity should provide disclosures in a tabular format for each line item on the income statement which contains any of the following expenses: purchases of inventory, employee compensation, depreciation, intangible asset amortization, and/or depreciation, depletion, and amortization. ASU 2024-03 also requires an entity to disclose total selling expenses. ASU 2024-03 may be adopted on a prospective or retrospective basis. We expect to adopt ASU 2024-03 for the fiscal year ending December 31, 2027, and are in the process of analyzing the impact of the ASU on our related disclosures.
