Accounting Policies [Abstract] |
Principles Of Consolidation | Principles of Consolidation – NNN’s consolidated financial statements include the accounts of each of the respective majority owned and controlled affiliates, including transactions whereby NNN has been determined to be the primary beneficiary in accordance with the Financial Accounting Standards Board (“FASB”) guidance included in Consolidation. All significant intercompany account balances and transactions have been eliminated. NNN applies the equity method of accounting to investments in partnerships and joint ventures that are not subject to control by NNN due to the significance of rights held by other parties. The TRS develops real estate through various joint venture development affiliate agreements. NNN consolidates certain joint venture development entities based upon either NNN being the primary beneficiary of the respective variable interest entity or NNN having a controlling interest over the respective entity. NNN eliminates significant intercompany balances and transactions and records a noncontrolling interest for its other partners’ ownership percentage.
Real Estate Portfolio | Real Estate Portfolio – NNN records the acquisition of real estate at cost, including acquisition and closing costs. The cost of properties developed by NNN includes direct and indirect costs of construction, property taxes, interest and other miscellaneous costs incurred during the development period until the project is substantially complete and available for occupancy. For the years ended December 31, 2012, 2011 and 2010, NNN recorded $1,540,000, $1,213,000 and $617,000 in capitalized interest, respectively. Purchase Accounting for Acquisition of Real Estate Subject to a Lease – In accordance with the FASB guidance on business combinations, the fair value of the real estate acquired with in-place leases is allocated to the acquired tangible assets, consisting of land, building and tenant improvements, and identified intangible assets and liabilities, consisting of the value of above-market and below-market leases, value of in-place leases and value of tenant relationships, based in each case on their relative fair values. The fair value of the tangible assets of an acquired leased property is determined by valuing the property as if it were vacant, and the “as-if-vacant” value is then allocated to land, building and tenant improvements based on the determination of the fair values of these assets. The as-if-vacant fair value of a property is provided to management by a qualified appraiser. In allocating the fair value of the identified intangible assets and liabilities of an acquired property, above-market and below-market in-place lease values are recorded as other assets or liabilities based on the present value (using an interest rate which reflects the risks associated with the leases acquired) of the difference between (i) the contractual amounts to be paid pursuant to the in-place leases, and (ii) management’s estimate of fair market lease rates for the corresponding in-place leases, measured over a period equal to the remaining term of the lease, including the probability of renewal periods. The capitalized above-market lease values are amortized as a reduction of rental income over the remaining terms of the respective leases. The capitalized below-market lease values are amortized as an increase to rental income over the initial term unless the Company believes that it is likely that the tenant would renew the option whereby the Company would amortize the value attributable to the renewal over the renewal period. The aggregate value of other acquired intangible assets, consisting of in-place leases, is measured by the excess of (i) the purchase price paid for a property after adjusting existing in-place leases to market rental rates over (ii) the estimated fair value of the property as-if-vacant, determined as set forth above. The value of in-place leases exclusive of the value of above-market and below-market in-place leases is amortized to expense over the remaining non-cancelable periods of the respective leases. If a lease were to be terminated prior to its stated expiration, all unamortized amounts relating to that lease would be written off. The value of tenant relationships is reviewed on individual transactions to determine if future value was derived from the acquisition. Intangible assets and liabilities consisted of the following as of December 31 (in thousands):
|  | 2012 |  | 2011
Intangible lease assets (included in Other assets): |  |  |  |
Value of above market in-place leases, net |  | $ | 6,679 |  |  | $ | 5,907 |
Value of in-place leases, net |  | 37,889 |  |  | 31,970 |
Intangible lease liabilities (included in Other liabilities): |  |  |  |
Value of below market in-place leases, net |  | 23,708 |  |  | 23,367 |
NNN's real estate is generally leased to tenants on a net lease basis, whereby the tenant is responsible for all operating expenses relating to the property, including property taxes, insurance, maintenance and repairs. The leases are accounted for using either the operating or the direct financing method. Such methods are described below: Operating method – Properties with leases accounted for using the operating method are recorded at the cost of the real estate. Revenue is recognized as rentals are earned and expenses (including depreciation) are charged to operations as incurred. Buildings are depreciated on the straight-line method over their estimated useful lives. Leasehold interests are amortized on the straight-line method over the terms of their respective leases. When scheduled rentals vary during the lease term, income is recognized on a straight-line basis so as to produce a constant periodic rent over the term of the lease. Accrued rental income is the aggregate difference between the scheduled rents which vary during the lease term and the income recognized on a straight-line basis. Direct financing method – Properties with leases accounted for using the direct financing method are recorded at their net investment (which at the inception of the lease generally represents the cost of the property). Unearned income is deferred and amortized into income over the lease terms so as to produce a constant periodic rate of return on NNN’s net investment in the leases. Real Estate – Held For Sale – The properties that are classified as held for sale at any given time may consist of properties that have been acquired in the marketplace with the intent to sell and properties that have been or are under contract for sale. The properties are recorded at acquisition cost, including the acquisition and closing costs. The cost of the real estate developed includes direct and indirect costs of construction, interest and other miscellaneous costs incurred during the development period until the project is substantially complete and available for occupancy. Real estate held for sale is not depreciated and is recorded at the lower of cost or fair value. In accordance with the FASB guidance included in Real Estate, NNN classifies its real estate held for sale as discontinued operations for each property in which rental revenues are generated. Impairment – Real Estate – Based upon events or changes in certain circumstances, management periodically assesses its Property Portfolio for possible impairment indicating that the carrying value of the asset, including accrued rental income, may not be recoverable through operations. Events or circumstances that may occur include significant changes in real estate market conditions and the ability of NNN to re-lease or sell properties that are currently vacant or become vacant. Management evaluates whether an impairment in value has occurred by comparing the estimated future cash flows (undiscounted and without interest charges), including the residual value of the real estate, with the carrying cost of the individual asset. If an impairment is indicated, a loss will be recorded for the amount by which the carrying value of the asset exceeds its fair value. Real Estate Dispositions – When real estate is disposed of, the related cost, accumulated depreciation or amortization and any accrued rental income for operating leases and the net investment for direct financing leases are removed from the accounts, and gains and losses from the dispositions are reflected in income. Gains from the disposition of real estate are generally recognized using the full accrual method in accordance with the FASB guidance included in Real Estate Sales, provided that various criteria relating to the terms of the sale and any subsequent involvement by NNN with the real estate sold are met. Lease termination fees are recognized when the related leases are cancelled and NNN no longer has a continuing obligation to provide services to the former tenants.
Valuation of Mortgages, Notes and Accrued Interest | Valuation of Mortgages, Notes and Accrued Interest – The reserve allowance related to the mortgages, notes and accrued interest is NNN’s best estimate of the amount of probable credit losses. The reserve allowance is determined on an individual note basis in reviewing any payment past due for over 90 days. Any outstanding amounts are written off against the reserve allowance when all possible means of collection have been exhausted.
Investment In Unconsolidated Affiliate and Commercial Mortgage Residual Interest | Investment in an Unconsolidated Affiliate – NNN accounts for its investment in an unconsolidated affiliate under the equity method of accounting. In September 2007, NNN entered into a joint venture, NNN Retail Properties Fund I LLC (the “NNN Crow JV”) with an affiliate of Crow Holdings Realty Partners IV, L.P., which is accounted for under the equity method of accounting. During September 2012, NNN Crow JV sold all of its assets and paid off its bank term loan as of December 31, 2012. Commercial Mortgage Residual Interests, at Fair Value – Commercial mortgage residual interests, classified as available for sale, are reported at their market values with unrealized gains and losses reported as other comprehensive income in stockholders’ equity. NNN recognizes the excess of all cash flows attributable to the commercial mortgage residual interests estimated at the acquisition/transaction date over the initial investment (the accretable yield) as interest income over the life of the beneficial interest using the effective yield method. Losses are considered other than temporary valuation impairments if and when there has been a change in the timing or amount of estimated cash flows, exclusive of changes in interest rates, that leads to a loss in value.
Cash And Cash Equivalents | Cash and Cash Equivalents – NNN considers all highly liquid investments with a maturity of three months or less when purchased to be cash equivalents. Cash and cash equivalents consist of cash and money market accounts. Cash equivalents are stated at cost plus accrued interest, which approximates fair value. Cash accounts maintained on behalf of NNN in demand deposits at commercial banks and money market funds may exceed federally insured levels; however, NNN has not experienced any losses in such accounts.
Valuation Of Receivables | Valuation of Receivables – NNN estimates the collectibility of its accounts receivable related to rents, expense reimbursements and other revenues. NNN analyzes accounts receivable and historical bad debt levels, customer credit-worthiness and current economic trends when evaluating the adequacy of the allowance for doubtful accounts. In addition, tenants in bankruptcy are analyzed and estimates are made in connection with the expected recovery of pre-petition and post-petition claims.
Goodwill | Goodwill – Goodwill arises from business combinations and represents the excess of the cost of an acquired entity over the net fair value amounts that were assigned to the assets acquired and the liabilities assumed. In accordance with the FASB guidance included in Goodwill, NNN performs impairment testing on goodwill by comparing fair value of its reporting units to carrying amount annually.
Debt Costs | Debt Costs – Debt costs incurred in connection with NNN’s $500,000,000 line of credit and mortgages payable have been deferred and are being amortized over the term of the respective loan commitment using the straight-line method, which approximates the effective interest method. Debt costs incurred in connection with the issuance of NNN’s notes payable have been deferred and are being amortized to interest expense over the term of the respective debt obligation using the effective interest method.
Revenue Recognition | Revenue Recognition – Rental revenues for non-development real estate assets are recognized when earned in accordance with the FASB guidance included in Leases, based on the terms of the lease of the leased asset. Rental revenues for properties under construction commence upon completion of construction of the leased asset and delivery of the leased asset to the tenant.
Earnings Per Share | Earnings Per Share – Earnings per share have been computed pursuant to the FASB guidance included in Earnings Per Share. The guidance requires classification of the Company’s unvested restricted share units which contain rights to receive nonforfeitable dividends, as participating securities requiring the two-class method of computing earnings per share. Under the two-class method, earnings per common share are computed by dividing the sum of distributed earnings to common stockholders and undistributed earnings allocated to common stockholders by the weighted average number of common shares outstanding for the period. In applying the two-class method, undistributed earnings are allocated to both common shares and participating securities based on the weighted average shares outstanding during the period.
Income Tax | Income Taxes – NNN has made an election to be taxed as a REIT under Sections 856 through 860 of the Internal Revenue Code of 1986, as amended (the “Code”), and related regulations. NNN generally will not be subject to federal income taxes on amounts distributed to stockholders, providing it distributes 100 percent of its REIT taxable income and meets certain other requirements for qualifying as a REIT. For each of the years in the three-year period ended December 31, 2012, NNN believes it has qualified as a REIT. Notwithstanding NNN’s qualification for taxation as a REIT, NNN is subject to certain state taxes on its income and real estate. NNN and its taxable REIT subsidiaries have made timely TRS elections pursuant to the provisions of the REIT Modernization Act. A taxable REIT subsidiary is able to engage in activities resulting in income that previously would have been disqualified from being eligible REIT income under the federal income tax regulations. As a result, certain activities of NNN which occur within its TRS entities are subject to federal and state income taxes (See Note 16). All provisions for federal income taxes in the accompanying consolidated financial statements are attributable to NNN’s taxable REIT subsidiaries and to OAMI’s built-in-gain tax liability. Income taxes are accounted for under the asset and liability method as required by the FASB guidance included in Income Taxes. Deferred tax assets and liabilities are recognized for the temporary differences based on estimated future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and operating loss and tax credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates in effect for the year in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date.
Fair Value Measurement | Fair Value Measurement – NNN’s estimates of fair value of financial and non-financial assets and liabilities based on the framework established in the fair value accounting guidance. The framework specifies a hierarchy of valuation inputs which was established to increase consistency, clarity and comparability in fair value measurements and related disclosures. The guidance describes a fair value hierarchy based upon three levels of inputs that may be used to measure fair value, two of which are considered observable and one that is considered unobservable. The following describes the three levels:
• | Level 1 – Valuation is based upon quoted prices in active markets for identical assets or liabilities.
• | Level 2 – Valuation is based upon inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices for similar assets or liabilities, quoted prices in markets that are not active or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.
• | Level 3 – Valuation is generated from model-based techniques that use at least one significant assumption not observable in the market. These unobservable assumptions reflect estimates of assumptions that market participants would use in pricing the asset or liability. Valuation techniques include option pricing models, discounted cash flow models and similar techniques.
New Accounting Pronouncements | New Accounting Pronouncements – In December 2011, the FASB issued Accounting Standards Update ("ASU") 2011-10, which clarifies the scope of current U.S. generally accepted accounting principles ("GAAP"). The amendments will resolve the diversity in practice about whether the guidance in subtopic 360-20 applies to the derecognition of in substance real estate when the parent ceases to have a controlling financial interest in a subsidiary that is in substance real estate because of a default by the subsidiary on its nonrecourse debt. The amendments in this update are effective for fiscal years, and interim periods within those years, beginning on or after June 15, 2012. The adoption of the standard did not have a significant impact on NNN's financial position or results of operations. In June 2011, the FASB issued ASU 2011-05 which amended its guidance on the presentation of comprehensive income in financial statements. The new guidance requires that all nonowner changes in stockholders' equity be presented either in a single continuous statement of comprehensive income or in two separate but consecutive statements. The provisions of this new guidance were effective for fiscal years, and interim periods within those years, beginning after December 15, 2011. The adoption of this guidance changed the presentation of NNN's consolidated financial statements but did not have an effect on NNN's results of operations. In December 2011, the FASB isuued ASU 2011-11 amending its guidance on offsetting assets and liabilities in financial statements. The objective of this update would be to require disclosure to facilitate comparison between those entities that prepare their financial statements on the basis of GAAP and those entities that prepare their financial statements on the basis of IFRS. The amendments in this update are effective for annual reporting periods beginning on or after January 1, 2013. NNN is currently evaluating the provisions to determine the potential impact, if any, the adoption will have on its financial position and results of operations. In December 2011, the FASB issued ASU 2011-12, which indefinitely defers certain provisions of ASU 2011-05, including a requirement for entities to present reclassification adjustments out of accumulated other comprehensive income by component in both the statement in which net earnings is presented and the statement in which other comprehensive income is presented. The effective dates and expected changes to NNN's presentation are the same as noted in ASU 2011-05 above.
Use Of Estimates | Use of Estimates – Additional critical accounting policies of NNN include management’s estimates and assumptions relating to the reporting of assets and liabilities, revenues and expenses and the disclosure of contingent assets and liabilities to prepare the consolidated financial statements in conformity with accounting principles generally accepted in the United States of America. Additional critical accounting policies include management’s estimates of the useful lives used in calculating depreciation expense relating to real estate assets, the recoverability of the carrying value of long-lived assets, including the commercial mortgage residual interests, the recoverability of the deferred income taxes, and the collectibility of receivables from tenants, including accrued rental income. Actual results could differ from those estimates.
Reclassification | Reclassification – Certain items in the prior year’s consolidated financial statements and notes to consolidated financial statements have been reclassified to conform to the 2012 presentation.
