Overview	'
	Overview
	Organization and Description of Business
	Douglas Emmett, Inc. is a fully integrated, self-administered and self-managed Real Estate Investment Trust (REIT). We are one of the largest owners and operators of high-quality office and multifamily properties in Los Angeles County, California and Honolulu, Hawaii. We focus on owning and acquiring a substantial share of top-tier office properties and premier multifamily communities in neighborhoods that possess significant supply constraints, high-end executive housing and key lifestyle amenities.
	Through our interest in Douglas Emmett Properties, LP (our operating partnership) and its subsidiaries, as well as our investment in our two institutional unconsolidated real estate funds (Funds), we own or partially own, manage, lease, acquire and develop real estate, consisting primarily of office and multifamily properties in Los Angeles County, California and Honolulu, Hawaii. As of December 31, 2013, we owned a consolidated portfolio of fifty-two office properties (including ancillary retail space) and nine multifamily properties, as well as the fee interests in two parcels of land subject to ground leases. Alongside our consolidated portfolio, we also manage and own equity interests in our Funds which, at December 31, 2013, owned eight additional office properties, for a combined sixty office properties in our total portfolio.
	The terms "us," "we" and "our" as used in these financial statements refer to Douglas Emmett, Inc. and its subsidiaries.
	Basis of Presentation
	The financial statements presented are the consolidated financial statements of Douglas Emmett, Inc. and its subsidiaries, including our operating partnership. All significant intercompany balances and transactions have been eliminated in our consolidated financial statements, and certain prior period amounts have been reclassified to conform with the current period presentation. Substantially all of our business is conducted through our consolidated operating partnership, in which other investors own a noncontrolling interest. See Note 9. Our business also includes a consolidated joint venture in which our operating partnership owns a two-thirds interest. The balances and results of the property owned by this consolidated joint venture are included in our financial statements.
	The accompanying financial statements have been prepared pursuant to the rules and regulations of the United States Securities and Exchange Commission (SEC) in conformity with Generally Accepted Accounting Principles of the United States (GAAP) as established by the Financial Accounting Standards Board (FASB) in the Accounting Standards Codification (ASC), including modifications issued under Accounting Standards Updates (ASUs). The accompanying financial statements include, in our opinion, all adjustments, consisting of normal recurring adjustments, necessary to present fairly the financial information set forth therein. Any reference to the number of properties, square footage and geography, 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.

Accounting Policies [Abstract]	'
Summary Of Significant Accounting Policies	'
	Summary of Significant Accounting Policies
	Use of Estimates
	The preparation of financial statements in conformity with GAAP requires management to make certain estimates and assumptions that affect the reported amounts in the consolidated financial statements and accompanying notes. Actual results could differ materially from those estimates.
	Segment Information
	Segment information is prepared on the same basis that our management reviews information for operational decision-making purposes. We operate two business segments: the acquisition, development, ownership and management of office real estate, and the acquisition, development, ownership and management of multifamily real estate.
	The products for our office segment include primarily rental of office space and other tenant services, including parking and storage space rental. The products for our multifamily segment include primarily rental of apartments and other tenant services, including parking and storage space rental. See Note 16.
	Investments in Real Estate
	We account for acquisitions of properties utilizing the purchase method, and include the results of operations of the acquired properties in our results of operations from their respective dates of acquisition. We expense transaction costs related to acquisitions when they are incurred.
	When we acquire a property, we determine the fair values of the tangible assets on an ‘‘as-if-vacant’’ basis. We use estimates of future cash flows, comparable sales, other relevant information obtained in connection with the acquisition of the property, and other valuation techniques to allocate the purchase price of each acquired property between land, buildings and improvements, tenant improvements and leasing costs, and identifiable intangible assets and liabilities such as amounts related to in-place at-market leases, acquired above- and below-market tenant leases, and acquired above- and below-market ground leases.
	The estimated fair value of acquired in-place at-market tenant leases represents the estimated costs that we would have incurred to lease the property to the occupancy level of the property at the date of acquisition, including the fair value of leasing commissions and legal costs. Additionally, we evaluate the time period over which such occupancy level would be achieved and include an estimate of the net operating costs (primarily real estate taxes, insurance and utilities) incurred during the lease-up period. We record above-market and below-market in-place lease intangibles as an asset or liability based on the present value (using a discount rate which reflects the risks associated with the leases acquired) of the difference between the contractual amounts to be received or paid pursuant to the in-place tenant or ground leases, respectively, and our estimate of fair market lease rates for the corresponding in-place leases, measured over a period equal to the remaining non-cancelable term of the lease. Our initial valuations and allocations are subject to change until the allocation is finalized within 12 months after the acquisition date. See Note 3.
	The values allocated to land, buildings and improvements, in-place leases, tenant improvements and leasing costs are depreciated on a straight-line basis using an estimated life of forty years for buildings; fifteen years for site improvements; the average term of existing leases in the building acquired for in-place lease values; and the respective lease term for tenant improvements and leasing costs. The values of above- and below-market tenant leases are amortized over the life of the related lease and recorded as either an increase (for below-market leases) or a decrease (for above-market leases) to rental income. The values of acquired above- and below-market ground leases are amortized over the life of the lease and recorded either as an increase (for below-market leases) or a decrease (for above-market leases) to rental operating expense. The amortization of acquired in-place leases is recorded as an adjustment to depreciation and amortization in the consolidated statements of operations. Any unamortized amounts relating to a lease that is terminated prior to its stated expiration are written off in the period of termination.
	We charge expenditures for repairs and maintenance operations as incurred, and capitalize significant improvements and costs incurred in the execution of leases. When assets are sold or retired, their costs and related accumulated depreciation are removed from the accounts with the resulting gains or losses reflected in discontinued operations for the period.
	Interest, insurance, property taxes and other costs incurred during the period of construction of real estate are capitalized. Cost capitalization of development and redevelopment activities begins during the predevelopment period, which we define as activities that are necessary to the development of the property.  We cease capitalization upon substantial completion of the project, but no later than one year from cessation of major construction activity.  We also cease capitalization when activities necessary to prepare the property for its intended use have been suspended. For the year ended December 31, 2013 we capitalized $101 thousand of costs related to our multifamily developments in Honolulu and Brentwood, which includes $75 thousand of capitalized interest expense. We did not capitalize any costs during 2012 and 2011 related to development or redevelopment activities.
	Investment in Unconsolidated Real Estate Funds
	At December 31, 2013, we managed and held equity interests in two Funds: Fund X and Partnership X. We held a 68.61% interest in Fund X, and an aggregate 24.25% interest in the properties held by Partnership X and its subsidiaries. We account for our investments in the Funds using the equity method because we have significant influence, but not control over the entities. Our investment balance represents our share of the net assets of the combined Funds, additional basis of approximately $3.1 million (primarily due to the inclusion of the cost of raising capital that is accounted for as part of our investment basis), and a note receivable with an outstanding balance of $2.7 million. See Note 18.
	Impairment of Long-Lived Assets
	We assess whether there has been impairment in the value of our long-lived assets whenever events or changes in circumstances indicate the carrying amount of an asset may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount to the undiscounted future cash flows expected to be generated by the asset. If the current carrying value exceeds the estimated undiscounted cash flows, an impairment loss is recorded equal to the difference between the asset’s current carrying value and its value based on the discounted estimated future cash flows. Assets to be disposed of are reported at the lower of the carrying amount or fair value, less costs to sell. Based upon such periodic assessments, no impairments occurred during 2013, 2012 or 2011.
	We assess whether there has been impairment in the value of our investments in our Funds periodically. An impairment charge is recorded when events or change in circumstances indicate that a decline in the fair value below the carrying value has occurred and such decline is other-than-temporary. The ultimate realization of the investments in our Funds is dependent on a number of factors, including the performance of the investment and market conditions. We will record an impairment charge if we determine that a decline in the value of an investment in one of our Funds is other-than-temporary.  Based upon such periodic assessments, no impairment occurred during 2013, 2012 or 2011.
	An asset is classified as an asset held for disposition when it meets certain requirements, including the approval of the sale of the asset, the marketing of the asset for sale, and our expectation that the sale will likely occur within the next 12 months. Upon classification of an asset as held for disposition, the net book value of the asset, excluding long-term debt, is included on the balance sheet as properties held for disposition, we cease to depreciate the asset, and the operating results of the asset are included in discontinued operations for all periods presented.
	Cash and Cash Equivalents
	For purposes of the consolidated statements of cash flows, we consider short-term investments with maturities of three months or less when purchased to be cash equivalents.
	Revenue and Gain Recognition
	Four basic criteria must be met before revenue can be recognized: persuasive evidence of an arrangement exists; services are rendered; the fee is fixed and determinable; and collectibility is reasonably assured. All leases are classified as operating leases. For all lease terms exceeding one year, rental income is recognized on a straight-line basis over the term of the lease. Deferred rent receivables represent rental revenue recognized on a straight-line basis in excess of billed rents. Lease termination fees, which are included in rental revenues in the accompanying consolidated statements of operations, are recognized when the related lease is canceled and we have no continuing obligation to provide services to such former tenant. We recorded total lease termination revenue of $576 thousand for 2013, $985 thousand for 2012 and $444 thousand for 2011.
	Estimated recoveries from tenants for real estate taxes, common area maintenance and other recoverable operating expenses are recognized as revenues in the period that the expenses are incurred. Subsequent to year-end, we perform reconciliations on a lease-by-lease basis and bill or credit each tenant for any cumulative annual adjustments. In addition, we record a capital asset for leasehold improvements constructed by us that are reimbursed by tenants, with the offsetting side of this accounting entry recorded to deferred revenue which is included in accrued expenses. The deferred revenue is amortized as additional rental revenue over the life of the related lease. Rental revenue from month-to-month leases or leases with no scheduled rent increases or other adjustments is recognized on a monthly basis when earned.
	The recognition of gains on sales of real estate requires that we measure the timing of a sale against various criteria related to the terms of the transaction, as well as any continuing involvement in the form of management or financial assistance associated with the property. If the sales criteria are not met, we defer gain recognition and account for the continued operations of the property by applying the finance, profit-sharing or leasing method. If the sales criteria have been met, we further analyze whether profit recognition is appropriate using the full accrual method. If the criteria to recognize profit using the full accrual method have not been met, we defer the gain and recognize it when the criteria are met or use the installment or cost recovery method as appropriate under the circumstances.
	Monitoring of Rents and Other Receivables
	We maintain an allowance for estimated losses that may result from the inability of tenants to make required payments. If a tenant fails to make contractual payments beyond any allowance, we may recognize bad debt expense in future periods equal to the amount of unpaid rent and deferred rent. We take into consideration many factors to evaluate the level of reserves necessary, including historical termination/default activity and current economic conditions. As of December 31, 2013 and 2012, we had an allowance for doubtful accounts of $10.7 million and $14.7 million, respectively.
	We generally do not require collateral or other security from our tenants other than letters of credit or cash security deposits. As of December 31, 2013 and 2012, we had a total of approximately $17.0 million and $19.1 million, respectively, of letters of credit held for security, as well as $35.5 million and $34.3 million, respectively, of cash security deposits.
	Deferred Loan Costs
	Costs incurred in issuing secured notes payable are capitalized. Deferred loan costs are included in other assets in the consolidated balance sheets at December 31, 2013 and 2012. The deferred loan costs are amortized to interest expense over the life of the respective loans. Any unamortized amounts upon early repayment of secured notes payable are written-off in the period of repayment. See Note 5.
	Interest Rate Agreements
	We generally manage our interest rate risk associated with floating rate borrowings by obtaining interest rate swap and interest rate cap contracts. The interest rate swap agreements that we utilize effectively modify our exposure to interest rate risk by converting our floating-rate debt to a fixed-rate basis, thus reducing the impact of interest-rate changes on future interest expense. These agreements involve the receipt of floating-rate amounts in exchange for fixed-rate interest payments over the life of the agreements without an exchange of the underlying principal amount. We do not use any other derivative instruments.
	We record all derivatives on the balance sheet at fair value on a gross basis. The accounting for changes in the fair value of derivatives depends on the intended use of the derivative and the resulting designation. Derivatives used to hedge the exposure to changes in the fair value of an asset, liability, or firm commitment attributable to a particular risk, are considered fair value hedges. Derivatives used to hedge the exposure to variability in expected future cash flows, or other types of forecasted transactions, are considered cash flow hedges.
	Our objective in using derivatives is to add stability to interest expense and to manage our exposure to interest rate movements and other identified risks. To accomplish this objective, we primarily use interest rate swaps as part of our cash flow hedging strategy. For derivatives designated as cash flow hedges, the effective portion of changes in the fair value of the derivative is initially reported in other comprehensive income (a component of equity outside of earnings) and subsequently reclassified to earnings when the hedged transaction affects earnings. The ineffective portion of changes in the fair value of the derivative is recognized directly in earnings. We assess the effectiveness of each hedging relationship by comparing the changes in fair value or cash flows of the derivative hedging instrument with the changes in fair value or cash flows of the designated hedged item or transaction. For derivatives not designated as hedges, changes in fair value are recognized in earnings. The fair value of these hedges is obtained through independent third-party valuation sources that use conventional valuation algorithms. See Note 8.
	Stock-Based Compensation
	We account for stock-based compensation, including stock options and long-term incentive plan units, using the fair value method of accounting. The estimated fair value of the stock options and the long-term incentive units is amortized over their respective vesting periods. See Note 11.
	Earnings Per Share
	Basic earnings per share is calculated by dividing the net income attributable to common stockholders for the period by the weighted average of common shares outstanding during the period. Diluted earnings per share 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. See Note 10.
	Income Taxes
	We have elected to be taxed as a REIT under the Internal Revenue Code of 1986, as amended (IRC), commencing with our initial taxable year ending December 31, 2006. To qualify as a REIT, we are required (among other things) to distribute at least 90% of our REIT taxable income to our stockholders and meet the various other requirements imposed by the IRC relating to matters such as operating results, asset holdings, distribution levels and diversity of stock ownership. Provided we qualify 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 qualify as a REIT in any taxable year, and were unable to avail ourselves of certain savings provisions set forth in the IRC, all of our taxable income would be subject to federal income tax at regular corporate rates, including any applicable alternative minimum tax.
	In addition, we are subject to taxation by various state and local jurisdictions, including those in which we transact business or reside. Our non taxable REIT subsidiaries, including our operating partnership, are either partnerships or disregarded entities for federal income tax purposes. Under applicable federal and state income tax rules, the allocated share of net income or loss from disregarded entities (including limited partnerships and S-Corporations) is reportable in the income tax returns of the respective partners and stockholders. Accordingly, no income tax provision is included in the accompanying consolidated financial statements.
	We have elected to treat several of our subsidiaries as taxable REIT subsidiaries (TRS) which generally may engage in any business, including the provision of customary or non-customary services for our tenants. A TRS is treated as a regular corporation and is subject to federal income tax and applicable state income and franchise taxes at regular corporate rates.  Our TRS subsidiaries did not have significant tax provisions or deferred income tax items for 2013, 2012 or 2011.
	Recently Issued Accounting Literature
	Changes to GAAP are established by the Financial Accounting Standards Board (FASB) in the form of Accounting Standard Updates (ASUs).  We consider the applicability and impact of all ASUs.
	In February 2013, the FASB issued ASU No. 2013-04, Obligations Resulting from Joint and Several Liability Arrangements for Which the Total Amount of the Obligation is Fixed at the Reporting Date (Topic 405), which provides guidance for the recognition, measurement and disclosure of obligations resulting from joint and several liability arrangements for which the total amount of the obligation within the scope of this ASU is fixed at the reporting date, except for obligations addressed within existing guidance in U.S. GAAP. ASU No. 2013-04 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2013, which for us means the first quarter of 2014. When adopted, ASU 2013-04 applies retroactively for existing joint and several liability arrangements within the scope of Subtopic 405-40. Although earlier application is permitted, we do not intend to adopt the ASU before the effective date. We do not expect this ASU to have a material impact on our financial position or results of operations, as we do not currently have any obligations within the scope of this ASU.
	In July 2013, the FASB issued ASU No. 2013-10, Inclusion of the Fed Funds Effective Swap Rate (or Overnight Index Swap Rate) as a Benchmark Interest Rate for Hedge Accounting Purposes (Topic 815), which permits for the inclusion of the Fed Funds Effective Swap Rate (OIS) as a U.S. benchmark interest rate for hedge accounting purposes, in addition to interest rates on direct Treasury obligations of the U.S. government (UST), and the London Interbank Offered Rate (LIBOR). The ASU amendments also remove the restriction on using different benchmark interest rates for similar hedges. ASU No. 2013-10 is effective prospectively for qualifying new or redesignated hedging relationships entered into on or after July 17, 2013. This ASU did not have a material impact on our financial position or results of operations.
	The FASB has not issued any other ASUs during 2013 or 2014 that we expect to be applicable and have a material impact on our future financial position or results of operations.

	Interest Rate Contracts
	Cash Flow Hedges of Interest Rate Risk
	We make use of interest rate swap and interest rate cap contracts to manage the risk associated with changes in the interest rates on our floating-rate borrowings. When we enter into a floating-rate term loan, we generally enter into an interest rate swap agreement for the equivalent principal amount, for a period covering the majority of the loan term, which effectively converts our floating-rate debt to a fixed-rate basis during that time. In limited instances, we make use of interest rate caps to limit our exposure to interest rate increases on underlying floating-rate debt.
	We may enter into derivative contracts that are intended to hedge certain economic risks, even though hedge accounting does not apply, or for which we elect to not apply hedge accounting. We do not use any other derivative instruments.
	As of December 31, 2013, the totals of our existing swaps that qualified as highly effective cash flow hedges were as follows:
	Interest Rate Derivative		Number of Instruments		Notional (in thousands)
	Interest Rate Swaps		7		$1,828,080
	Interest Rate Caps		2		$111,920
	As of December 31, 2013, the totals of our Funds existing swaps that qualified as highly effective cash flow hedges were as follows:
	Interest Rate Derivative		Number of Instruments		Notional (in thousands)
	Interest Rate Swap		1		$325,000
	Non-designated Hedges
	Derivatives not designated as hedges are not speculative. As of December 31, 2013, we had the following outstanding interest rate derivatives that were not designated for accounting purposes as hedging instruments, but were used to hedge our economic exposure to interest rate risk:
	Interest Rate Derivative		Number of Instruments		Notional (in thousands)
	Purchased Caps		4		$100,000
	Credit-risk-related Contingent Features
	We have agreements with each of our derivative counterparties that contain a provision under which we could also be declared in default on our derivative obligations if we default on the underlying indebtedness that we are hedging, including any default where repayment of the indebtedness has not been accelerated by the lender. There have been no events of default with respect to any of our derivatives.
	As of December 31, 2013 and 2012, the fair value of our derivatives in a net liability position, when aggregated by counterparty, was $67.2 million and $107.4 million, respectively, which includes accrued interest but excludes any adjustment for nonperformance risk related to these agreements. As of December 31, 2013 and 2012, our Funds did not have any derivatives in a net liability position.
	Accounting for Interest Rate Contracts
	For hedging instruments designated as cash flow hedges, gain or loss recognition are generally matched to the earnings effect of the related hedged item or transaction, with any resulting hedge ineffectiveness recorded as interest expense. Hedge ineffectiveness is determined by comparing the changes in the fair value or cash flows of the hedge to the changes in the fair value or cash flows of the related hedged item or transaction. All other changes in the fair value of these hedges are recorded in accumulated other comprehensive income (loss) (AOCI), which is a component of equity outside of earnings. Amounts reported in AOCI related to our hedges are then reclassified to interest expense as interest payments are made on the hedged item or transaction. Amounts reported in AOCI related to our Funds' hedges are reclassified to income (loss) including depreciation, from unconsolidated real estate funds as interest payments are made by our Funds on their hedged items or transactions. Changes in fair value of derivatives not designated as hedges are recognized as interest expense.
	The change in net unrealized gains and losses related to our cash flow hedges reflects a reclassification from AOCI to interest expense, which increased interest expense by $36.3 million in 2013, $55.7 million in 2012 and $80.9 million in 2011. The change in net unrealized gains and losses related to our Fund's cash flow hedges reflects a reclassification from AOCI to income (loss) including depreciation, from unconsolidated real estate funds, which decreased the income (increased the loss) by $549 thousand in 2013, $5.5 million in 2012 and $6.6 million in 2011.
	The cash flow swaps that we terminated in November 2010 had an AOCI balance of $13.9 million at the time they were terminated. Amortization of $3.5 million of this balance was included as part of the reclassification from AOCI to interest expense in 2010, and the remaining $10.4 million was reclassified in 2011. The cash flow swaps that we terminated in December 2011 had an AOCI balance of $10.1 million at the time they were terminated. Amortization of $1.3 million of this balance was included as part of the reclassification from AOCI to interest expense in 2011, and the remaining $8.8 million was reclassified from AOCI to interest expense in 2012.
	We estimate an additional $35.3 million of our AOCI related to our derivatives designated as cash flow hedges will be reclassified as an increase to interest expense during the next twelve months, and $841 thousand of our AOCI related to our Funds derivatives designated as cash flow hedges will be reclassified as a decrease to income (loss) including depreciation, from unconsolidated real estate funds during the next twelve months.
	The ineffectiveness attributable to mismatches between certain interest rate contracts and the corresponding items against which they were designated to hedge, that was reclassified from AOCI to interest expense, produced a loss of $85 thousand in 2013, and a gain of $4 thousand in 2012.
	The ineffectiveness attributable to mismatches between certain interest rate contracts and the corresponding items against which they were designated to hedge produced a loss of $64 thousand in 2012, and a gain of $50 thousand in 2011.
	Changes in fair value of derivatives not designated as hedges have been recognized in earnings for all periods. The aggregate net asset fair value of these swaps decreased by $4 thousand in 2013, $42 thousand in 2012 and $371 thousand in 2011. These decreases in net asset fair value were recorded as additional interest expense.

Equity	'
	Equity
	We had 142.6 million shares of common stock and 29.1 million operating partnership units and fully-vested LTIP units outstanding as of December 31, 2013. Noncontrolling interests in our operating partnership relate to interests in our operating partnership that are not owned by us. Noncontrolling interests represented approximately 17% of our operating partnership as of December 31, 2013. A unit in our operating partnership and a share of our common stock have essentially the same economic characteristics, as they share equally in the total net income or loss distributions of our operating partnership.  Investors who own units in our operating partnership have the right to cause our operating partnership to redeem any or all of their units in our operating partnership for an amount of cash per unit equal to the then current market value of one share of common stock, or, at our election, shares of our common stock on a one-for-one basis. Noncontrolling interests also include a one-third interest of a minority partner in a consolidated joint venture which owns an office building in Honolulu, Hawaii.
	Equity Sales, Conversions and Repurchases
	During 2011, approximately 714 thousand operating partnership units were converted to shares of our common stock, and we sold 6.2 million shares of our common stock in open market transactions under our ATM program for net proceeds of approximately $117.8 million after commissions and other expenses. During 2012, approximately 3.2 million units in our operating partnership were converted to shares of our common stock, and 6.9 million shares of our common stock were sold in open market transactions under our ATM program for net proceeds of approximately $128.3 million after commissions and other expenses. During 2013, approximately 1.4 million units in our operating partnership were exchanged for shares of our common stock and approximately 13 thousand units were redeemed for cash. We did not sell any shares of our common stock during 2013. During the third quarter of 2012, we instituted a new ATM program permitting sales of up to an additional $300.0 million of stock, none of which has been sold as of December 31, 2013.

	Stock-Based Compensation
	2006 Omnibus Stock Incentive Plan
	The Douglas Emmett, Inc. 2006 Omnibus Stock Incentive Plan, as amended, our stock incentive plan, permits us to make grants of incentive stock options, non-qualified stock options, stock appreciation rights, deferred stock awards, restricted stock awards, dividend equivalent rights and other stock-based awards. We had an aggregate of 18.9 million shares available for grant as of December 31, 2013, although “full value” awards (such as deferred stock awards, restricted stock awards and LTIP unit awards) are counted against our stock incentive plan overall limits as two shares (rather than one), while options and Stock Appreciation Rights are counted as one share (0.9 shares for options or Stock Appreciation Rights with terms of five years or less). The number of shares reserved under our stock incentive plan is also subject to adjustment in the event of a stock split, stock dividend or other change in our capitalization. Generally, shares that are forfeited or canceled from awards under our stock incentive plan also will be available for future awards.
	Our stock incentive plan is administered by the compensation committee of our board of directors. The compensation committee may interpret our stock incentive plan and may make all determinations necessary or desirable for the administration of our plan. The committee has full power and authority to select the participants to whom awards will be granted, to make any combination of awards to participants, to accelerate the exercisability or vesting of any award and to determine the specific terms and conditions of each award, subject to the provisions of our stock incentive plan. All full-time and part-time officers, employees, directors and other key persons (including consultants and prospective employees) are eligible to participate in our stock incentive plan.
	Other stock-based awards under our stock incentive plan include awards that are valued in whole or in part by reference to shares of our common stock, including convertible preferred stock, convertible debentures and other convertible or exchangeable securities, partnership interests in a subsidiary or our operating partnership, awards valued by reference to book value, fair value or performance of a subsidiary and any class of profits interest or limited liability company membership interest. We have made certain awards in the form of a separate series of units of limited partnership interests in our operating partnership called long term incentive plan units ("LTIP Units"), which can be granted either as free-standing awards or in tandem with other awards under our stock incentive plan. Our LTIP Units were valued by reference to the value of our common stock at the time of grant, and are subject to such conditions and restrictions as the compensation committee may determine, including continued employment or service, computation of financial metrics and/or achievement of pre-established performance goals and objectives.
	We grant equity compensation as a part of the annual incentive compensation to our key employees each year, a portion of which is fully vested at the date of grant, and the remainder of which vests in three equal annual installments over the three calendar years following the grant. We accrue compensation expense during each year for the portion of the annual bonuses which we expect to pay out in the form of immediately vested equity grants. Grants with respect to years prior to 2012, were awarded shortly after the respective year end, but commencing in 2012, we awarded the grants before the respective year end. Compensation expense for LTIP Units which are not vested at the grant date is recognized on a straight-line basis over the requisite service period for each separately vesting portion of the award. Compensation expense for options which are not vested at the grant date is recognized on a straight-line basis over the requisite service period for the entire award. Certain amounts of equity compensation expense are capitalized for employees who provide leasing and construction services.
	We granted LTIP Units to key employees totaling approximately 644 thousand in 2013, 1.2 million in 2012 and 623 thousand in 2011.
	Each year, we grant LTIP Units to our non-employee directors which vest ratably over the year of grant in lieu of cash retainers; these awards totaled approximately 19 thousand in 2013, 46 thousand in 2012 and 23 thousand in 2011. Every three years, we also make long-term grants of LTIP Units to our non-employee directors vesting over the next three years. We made aggregate grants of this type to our directors of approximately 54 thousand units at the end of 2012. When a new director joins our board, we make pro rata grants vesting over the remainder of the three years; those grants totaled 1 thousand LTIP units in 2012 and 7 thousand units in 2011.
	Total net equity compensation expense during 2013, 2012 and 2011 for equity grants was $10.0 million, $10.6 million, and $8.0 million, respectively. These amounts do not include (i) capitalized equity compensation totaling $800 thousand, $561 thousand, and $578 thousand during 2013, 2012 and 2011, respectively, and (ii) equity grants fully vested at the time of grant issued during 2013, 2012 and 2011 totaling $4.1 million, $3.0 million, and $2.8 million, respectively, to satisfy a portion of the annual bonuses that were accrued during the prior year. Total net equity compensation expense is include in general and administrative expenses in the consolidated statements of operations.
	We calculate the fair value of the LTIP Units granted using the market value of our common stock on the date of grant, and a discount estimated by a third-party consultant for post-vesting restrictions. The total grant date fair value of LTIP Units which vested in 2013, 2012 and 2011 was $10.9 million, $13.5 million and $8.1 million, respectively. Total unrecognized compensation cost related to nonvested option and LTIP Unit awards was $9.1 million at December 31, 2013. This expense will be recognized over a weighted-average term of twenty-one months.

Fair Value of Financial Instruments	'
	Fair Value of Financial Instruments
	Our estimates of the fair value of financial instruments at December 31, 2013 and 2012 were determined using available market information and appropriate valuation methods. Considerable judgment is necessary to interpret market data and develop estimated fair value. The use of different market assumptions or estimation methods may have a material effect on the estimated fair value amounts.
	The FASB fair value framework includes a hierarchy that distinguishes between assumptions based on market data obtained from sources independent of the reporting entity, and the reporting entity’s own assumptions about market-based inputs.  Level 1 inputs utilize unadjusted quoted prices in active markets for identical assets or liabilities.  Level 2 inputs are observable either directly or indirectly for similar assets and liabilities in active markets.  Level 3 inputs are unobservable assumptions generated by the reporting entity.
	The carrying amounts for cash and cash equivalents, tenant receivables, deferred rent receivables, interest payable, accounts payable and accrued liabilities, security deposits and dividends payable approximate fair value because of the short-term nature of these instruments.
	We have typically financed our capital needs through short-term lines of credit and long-term secured mortgages.  See Note 6. We calculate the fair value of our secured notes payable by calculating the credit-adjusted present value of the principal and interest payments related to our debt using current market interest rates (assuming the loans are outstanding through maturity) and any changes to underlying collateral.  We have determined that the fair value of our secured notes payable is calculated using Level 2 inputs under the fair value hierarchy. At December 31, 2013, the aggregate fair value of our secured notes payable was estimated to be approximately $3.26 billion, compared to their carrying value of $3.24 billion. As of December 31, 2012, the aggregate fair value of our secured notes payable was estimated to be approximately $3.51 billion, compared to their carrying value of $3.44 billion.
	We use interest rate swaps and caps to manage interest rate risk resulting from variable interest payments on our floating rate debt.  See Note 8. These financial instruments are carried on our balance sheet at fair value based on assumptions used by market participants in pricing the asset or liability. The valuation of our interest rate swaps and caps is determined 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 implied volatilities.  We incorporate credit valuation adjustments to appropriately reflect both our own nonperformance risk and the respective counterparty’s nonperformance risk in the fair value measurements.  In adjusting the fair value of our derivative contracts for the effect of nonperformance risk, we considered the impact of netting and any applicable credit enhancements, such as collateral postings, thresholds, mutual puts and guarantees.  We have determined that our derivative valuations in their entirety are classified in Level 2 of the fair value hierarchy.
	We did not have any fair value measurements using significant unobservable inputs (Level 3) as of December 31, 2013.
	The table below (in thousands) presents the derivative liabilities presented in our financial statements at their estimated fair value on a gross basis without reflecting any net settlement positions with the same counterparty:

	We lease space to tenants primarily under non-cancelable operating leases that generally contain provisions for a base rent plus reimbursement for certain operating expenses.  Operating expense reimbursements are reflected in our consolidated statements of operations as tenant recoveries.
	We also lease space to certain tenants under noncancelable leases that provide for percentage rents based upon tenant revenues. Percentage rental income totaled $576 thousand for 2013, $658 thousand for 2012 and $591 thousand for 2011.
	Future minimum base rentals on our non-cancelable office and ground operating leases at December 31, 2013 were as follows (in thousands):

	Commitments and Contingencies
	Legal Proceedings
	We are subject to various legal proceedings and claims that arise in the ordinary course of business. Excluding ordinary, routine litigation incidental to our business, we are not currently a party to any legal proceedings that we believe would reasonably be expected to have a materially adverse effect on our business, financial condition or results of operations.
	Concentration of Credit Risk
	Our properties are located in Los Angeles County, California and Honolulu, Hawaii. 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. We perform ongoing credit evaluations of our tenants for potential credit losses. In addition, we have financial instruments that subject us to credit risk, which consist primarily of accounts receivable, deferred rents receivable and interest rate contracts. We maintain our cash and cash equivalents at high quality financial institutions with investment grade ratings. Interest bearing accounts at each U.S. banking institution are insured by the Federal Deposit Insurance Corporation up to $250 thousand. We have not experienced any losses on our deposited cash.
	Asset Retirement Obligations
	Conditional asset retirement obligations represent a legal obligation to perform an asset retirement activity in which the timing and/or method of settlement is conditional on a future event that may or may not be within our control. A liability for a conditional asset retirement obligation must be recorded if the fair value of the obligation can be reasonably estimated. Environmental site assessments and investigations have identified twenty properties in our consolidated portfolio containing asbestos, which would have to be removed in compliance with applicable environmental regulations if these properties undergo major renovations or are demolished. As of December 31, 2013, the obligations to remove the asbestos from these properties have indeterminable settlement dates, and we are unable to reasonably estimate the fair value of the associated conditional asset retirement obligation.
	Guarantees
	On April 30, 2013, one of our Funds closed a $325.0 million loan to refinance an existing loan. The new loan matures on May 1, 2018, and carries interest that is effectively fixed by an interest rate swap which matures on May 1, 2017. We made certain environmental and other limited indemnities and guarantees covering customary non-recourse carve outs under this loan, and guaranteed the related swap, although we have an indemnity from the Fund for any amounts that we would be required to pay under these agreements. As of December 31, 2013 the maximum future payments under the swap agreement were approximately $6.6 million.  As of December 31, 2013, all obligations under the loan and swap agreements have been performed by the Fund in accordance with the terms of those agreements.
	Tenant Concentrations
	In 2013, 2012 and 2011, no tenant accounted for more than 10% of our total rental revenue and tenant recoveries.

	Segment Reporting
	Segment information is prepared on the same basis that we review information for operational decision-making purposes.  We operate in two business segments: (i) the acquisition, redevelopment, ownership and management of office real estate and (ii) the acquisition, redevelopment, ownership and management of multifamily real estate.  The services for our office segment primarily include rental of office space and other tenant services, including parking and storage space rental.  The services for our multifamily segment include rental of apartments and other tenant services, including parking and storage space rental.
	Asset information by segment is not reported because we do not use this measure to assess performance or make decisions to allocate resources.  Therefore, depreciation and amortization expense is not allocated among segments.  General and administrative expenses and interest 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 may calculate segment profit in the same manner.  We consider segment profit to be an appropriate supplemental measure to net income because it can assist both investors and management in understanding the core operations of our properties.

	Investments in Unconsolidated Real Estate Funds
	We manage and own an equity interest in two Funds, Fund X and Partnership X, through which we and institutional investors own 8 buildings totaling 1.8 million square feet in our core markets.  At December 31, 2013, we held a 68.61% interest in Fund X, and an aggregate 24.25% interest in the properties held by Partnership X.
	During the first quarter of 2013, we acquired an additional 3.3% interest in Fund X, and an additional 0.9% interest in Partnership X, from an existing investor for an aggregate of approximately $8.0 million in cash.  During the first quarter of 2012, we acquired an additional 16.3% interest in Fund X from existing investors for approximately $33.4 million in cash.
	Our investment in our unconsolidated real estate funds includes a note receivable. On April 3, 2013, we loaned $2.9 million to a related party investor in connection with a capital call made by Fund X. The loan carries interest at one month LIBOR plus 2.5%, and is due and payable no later than April 1, 2017, with mandatory prepayments equal to any distributions with respect to the related party's interest in Fund X. As of December 31, 2013, the balance outstanding on the loan was $2.7 million.
	The table below (in thousands) presents selected financial information for Fund X and Partnership X (on a combined basis).  The accounting policies of Fund X and Partnership X are consistent with those of the Company. The amounts presented represent 100% (not our pro-rata share) of amounts related to these Funds, and are based upon historical acquired book value:

Summary Of Significant Accounting Policies (Policy)	12 Months Ended
	Dec. 31, 2013
Accounting Policies [Abstract]	'
Use of Estimates	'
	Use of Estimates
	The preparation of financial statements in conformity with GAAP requires management to make certain estimates and assumptions that affect the reported amounts in the consolidated financial statements and accompanying notes. Actual results could differ materially from those estimates.
Segment Information	'
	Segment Information
	Segment information is prepared on the same basis that our management reviews information for operational decision-making purposes. We operate two business segments: the acquisition, development, ownership and management of office real estate, and the acquisition, development, ownership and management of multifamily real estate.
	The products for our office segment include primarily rental of office space and other tenant services, including parking and storage space rental. The products for our multifamily segment include primarily rental of apartments and other tenant services, including parking and storage space rental. See Note 16.
Investments in Real Estate	'
	Investments in Real Estate
	We account for acquisitions of properties utilizing the purchase method, and include the results of operations of the acquired properties in our results of operations from their respective dates of acquisition. We expense transaction costs related to acquisitions when they are incurred.
	When we acquire a property, we determine the fair values of the tangible assets on an ‘‘as-if-vacant’’ basis. We use estimates of future cash flows, comparable sales, other relevant information obtained in connection with the acquisition of the property, and other valuation techniques to allocate the purchase price of each acquired property between land, buildings and improvements, tenant improvements and leasing costs, and identifiable intangible assets and liabilities such as amounts related to in-place at-market leases, acquired above- and below-market tenant leases, and acquired above- and below-market ground leases.
	The estimated fair value of acquired in-place at-market tenant leases represents the estimated costs that we would have incurred to lease the property to the occupancy level of the property at the date of acquisition, including the fair value of leasing commissions and legal costs. Additionally, we evaluate the time period over which such occupancy level would be achieved and include an estimate of the net operating costs (primarily real estate taxes, insurance and utilities) incurred during the lease-up period. We record above-market and below-market in-place lease intangibles as an asset or liability based on the present value (using a discount rate which reflects the risks associated with the leases acquired) of the difference between the contractual amounts to be received or paid pursuant to the in-place tenant or ground leases, respectively, and our estimate of fair market lease rates for the corresponding in-place leases, measured over a period equal to the remaining non-cancelable term of the lease. Our initial valuations and allocations are subject to change until the allocation is finalized within 12 months after the acquisition date. See Note 3.
	The values allocated to land, buildings and improvements, in-place leases, tenant improvements and leasing costs are depreciated on a straight-line basis using an estimated life of forty years for buildings; fifteen years for site improvements; the average term of existing leases in the building acquired for in-place lease values; and the respective lease term for tenant improvements and leasing costs. The values of above- and below-market tenant leases are amortized over the life of the related lease and recorded as either an increase (for below-market leases) or a decrease (for above-market leases) to rental income. The values of acquired above- and below-market ground leases are amortized over the life of the lease and recorded either as an increase (for below-market leases) or a decrease (for above-market leases) to rental operating expense. The amortization of acquired in-place leases is recorded as an adjustment to depreciation and amortization in the consolidated statements of operations. Any unamortized amounts relating to a lease that is terminated prior to its stated expiration are written off in the period of termination.
	We charge expenditures for repairs and maintenance operations as incurred, and capitalize significant improvements and costs incurred in the execution of leases. When assets are sold or retired, their costs and related accumulated depreciation are removed from the accounts with the resulting gains or losses reflected in discontinued operations for the period.
	Interest, insurance, property taxes and other costs incurred during the period of construction of real estate are capitalized. Cost capitalization of development and redevelopment activities begins during the predevelopment period, which we define as activities that are necessary to the development of the property.  We cease capitalization upon substantial completion of the project, but no later than one year from cessation of major construction activity.  We also cease capitalization when activities necessary to prepare the property for its intended use have been suspended. For the year ended December 31, 2013 we capitalized $101 thousand of costs related to our multifamily developments in Honolulu and Brentwood, which includes $75 thousand of capitalized interest expense. We did not capitalize any costs during 2012 and 2011 related to development or redevelopment activities.
Investment in Unconsolidated Real Estate Funds	'
	Investment in Unconsolidated Real Estate Funds
	At December 31, 2013, we managed and held equity interests in two Funds: Fund X and Partnership X. We held a 68.61% interest in Fund X, and an aggregate 24.25% interest in the properties held by Partnership X and its subsidiaries. We account for our investments in the Funds using the equity method because we have significant influence, but not control over the entities. Our investment balance represents our share of the net assets of the combined Funds, additional basis of approximately $3.1 million (primarily due to the inclusion of the cost of raising capital that is accounted for as part of our investment basis), and a note receivable with an outstanding balance of $2.7 million. See Note 18.
Impairment of Long-Lived Assets	'
	Impairment of Long-Lived Assets
	We assess whether there has been impairment in the value of our long-lived assets whenever events or changes in circumstances indicate the carrying amount of an asset may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount to the undiscounted future cash flows expected to be generated by the asset. If the current carrying value exceeds the estimated undiscounted cash flows, an impairment loss is recorded equal to the difference between the asset’s current carrying value and its value based on the discounted estimated future cash flows. Assets to be disposed of are reported at the lower of the carrying amount or fair value, less costs to sell. Based upon such periodic assessments, no impairments occurred during 2013, 2012 or 2011.
	We assess whether there has been impairment in the value of our investments in our Funds periodically. An impairment charge is recorded when events or change in circumstances indicate that a decline in the fair value below the carrying value has occurred and such decline is other-than-temporary. The ultimate realization of the investments in our Funds is dependent on a number of factors, including the performance of the investment and market conditions. We will record an impairment charge if we determine that a decline in the value of an investment in one of our Funds is other-than-temporary.  Based upon such periodic assessments, no impairment occurred during 2013, 2012 or 2011.
	An asset is classified as an asset held for disposition when it meets certain requirements, including the approval of the sale of the asset, the marketing of the asset for sale, and our expectation that the sale will likely occur within the next 12 months. Upon classification of an asset as held for disposition, the net book value of the asset, excluding long-term debt, is included on the balance sheet as properties held for disposition, we cease to depreciate the asset, and the operating results of the asset are included in discontinued operations for all periods presented.
Cash and Cash Equivalents	'
	Cash and Cash Equivalents
	For purposes of the consolidated statements of cash flows, we consider short-term investments with maturities of three months or less when purchased to be cash equivalents.
Revenue and Gain Recognition	'
	Revenue and Gain Recognition
	Four basic criteria must be met before revenue can be recognized: persuasive evidence of an arrangement exists; services are rendered; the fee is fixed and determinable; and collectibility is reasonably assured. All leases are classified as operating leases. For all lease terms exceeding one year, rental income is recognized on a straight-line basis over the term of the lease. Deferred rent receivables represent rental revenue recognized on a straight-line basis in excess of billed rents. Lease termination fees, which are included in rental revenues in the accompanying consolidated statements of operations, are recognized when the related lease is canceled and we have no continuing obligation to provide services to such former tenant. We recorded total lease termination revenue of $576 thousand for 2013, $985 thousand for 2012 and $444 thousand for 2011.
	Estimated recoveries from tenants for real estate taxes, common area maintenance and other recoverable operating expenses are recognized as revenues in the period that the expenses are incurred. Subsequent to year-end, we perform reconciliations on a lease-by-lease basis and bill or credit each tenant for any cumulative annual adjustments. In addition, we record a capital asset for leasehold improvements constructed by us that are reimbursed by tenants, with the offsetting side of this accounting entry recorded to deferred revenue which is included in accrued expenses. The deferred revenue is amortized as additional rental revenue over the life of the related lease. Rental revenue from month-to-month leases or leases with no scheduled rent increases or other adjustments is recognized on a monthly basis when earned.
	The recognition of gains on sales of real estate requires that we measure the timing of a sale against various criteria related to the terms of the transaction, as well as any continuing involvement in the form of management or financial assistance associated with the property. If the sales criteria are not met, we defer gain recognition and account for the continued operations of the property by applying the finance, profit-sharing or leasing method. If the sales criteria have been met, we further analyze whether profit recognition is appropriate using the full accrual method. If the criteria to recognize profit using the full accrual method have not been met, we defer the gain and recognize it when the criteria are met or use the installment or cost recovery method as appropriate under the circumstances.
Monitoring of Rents and Other Receivables	'
	Monitoring of Rents and Other Receivables
	We maintain an allowance for estimated losses that may result from the inability of tenants to make required payments. If a tenant fails to make contractual payments beyond any allowance, we may recognize bad debt expense in future periods equal to the amount of unpaid rent and deferred rent. We take into consideration many factors to evaluate the level of reserves necessary, including historical termination/default activity and current economic conditions. As of December 31, 2013 and 2012, we had an allowance for doubtful accounts of $10.7 million and $14.7 million, respectively.
	We generally do not require collateral or other security from our tenants other than letters of credit or cash security deposits. As of December 31, 2013 and 2012, we had a total of approximately $17.0 million and $19.1 million, respectively, of letters of credit held for security, as well as $35.5 million and $34.3 million, respectively, of cash security deposits.
Deferred Loan Costs	'
	Deferred Loan Costs
	Costs incurred in issuing secured notes payable are capitalized. Deferred loan costs are included in other assets in the consolidated balance sheets at December 31, 2013 and 2012. The deferred loan costs are amortized to interest expense over the life of the respective loans. Any unamortized amounts upon early repayment of secured notes payable are written-off in the period of repayment. See Note 5.
Interest Rate Agreements	'
	Interest Rate Agreements
	We generally manage our interest rate risk associated with floating rate borrowings by obtaining interest rate swap and interest rate cap contracts. The interest rate swap agreements that we utilize effectively modify our exposure to interest rate risk by converting our floating-rate debt to a fixed-rate basis, thus reducing the impact of interest-rate changes on future interest expense. These agreements involve the receipt of floating-rate amounts in exchange for fixed-rate interest payments over the life of the agreements without an exchange of the underlying principal amount. We do not use any other derivative instruments.
	We record all derivatives on the balance sheet at fair value on a gross basis. The accounting for changes in the fair value of derivatives depends on the intended use of the derivative and the resulting designation. Derivatives used to hedge the exposure to changes in the fair value of an asset, liability, or firm commitment attributable to a particular risk, are considered fair value hedges. Derivatives used to hedge the exposure to variability in expected future cash flows, or other types of forecasted transactions, are considered cash flow hedges.
	Our objective in using derivatives is to add stability to interest expense and to manage our exposure to interest rate movements and other identified risks. To accomplish this objective, we primarily use interest rate swaps as part of our cash flow hedging strategy. For derivatives designated as cash flow hedges, the effective portion of changes in the fair value of the derivative is initially reported in other comprehensive income (a component of equity outside of earnings) and subsequently reclassified to earnings when the hedged transaction affects earnings. The ineffective portion of changes in the fair value of the derivative is recognized directly in earnings. We assess the effectiveness of each hedging relationship by comparing the changes in fair value or cash flows of the derivative hedging instrument with the changes in fair value or cash flows of the designated hedged item or transaction. For derivatives not designated as hedges, changes in fair value are recognized in earnings. The fair value of these hedges is obtained through independent third-party valuation sources that use conventional valuation algorithms. See Note 8.
Stock-Based Compensation	'
	Stock-Based Compensation
	We account for stock-based compensation, including stock options and long-term incentive plan units, using the fair value method of accounting. The estimated fair value of the stock options and the long-term incentive units is amortized over their respective vesting periods. See Note 11.
Earnings (Loss) Per Share)	'
	Earnings Per Share
	Basic earnings per share is calculated by dividing the net income attributable to common stockholders for the period by the weighted average of common shares outstanding during the period. Diluted earnings per share 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. See Note 10.
Income Taxes	'
	Income Taxes
	We have elected to be taxed as a REIT under the Internal Revenue Code of 1986, as amended (IRC), commencing with our initial taxable year ending December 31, 2006. To qualify as a REIT, we are required (among other things) to distribute at least 90% of our REIT taxable income to our stockholders and meet the various other requirements imposed by the IRC relating to matters such as operating results, asset holdings, distribution levels and diversity of stock ownership. Provided we qualify 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 qualify as a REIT in any taxable year, and were unable to avail ourselves of certain savings provisions set forth in the IRC, all of our taxable income would be subject to federal income tax at regular corporate rates, including any applicable alternative minimum tax.
	In addition, we are subject to taxation by various state and local jurisdictions, including those in which we transact business or reside. Our non taxable REIT subsidiaries, including our operating partnership, are either partnerships or disregarded entities for federal income tax purposes. Under applicable federal and state income tax rules, the allocated share of net income or loss from disregarded entities (including limited partnerships and S-Corporations) is reportable in the income tax returns of the respective partners and stockholders. Accordingly, no income tax provision is included in the accompanying consolidated financial statements.
	We have elected to treat several of our subsidiaries as taxable REIT subsidiaries (TRS) which generally may engage in any business, including the provision of customary or non-customary services for our tenants. A TRS is treated as a regular corporation and is subject to federal income tax and applicable state income and franchise taxes at regular corporate rates.  Our TRS subsidiaries did not have significant tax provisions or deferred income tax items for 2013, 2012 or 2011.
Recently Issued Accounting Literature	'
	Recently Issued Accounting Literature
	Changes to GAAP are established by the Financial Accounting Standards Board (FASB) in the form of Accounting Standard Updates (ASUs).  We consider the applicability and impact of all ASUs.
	In February 2013, the FASB issued ASU No. 2013-04, Obligations Resulting from Joint and Several Liability Arrangements for Which the Total Amount of the Obligation is Fixed at the Reporting Date (Topic 405), which provides guidance for the recognition, measurement and disclosure of obligations resulting from joint and several liability arrangements for which the total amount of the obligation within the scope of this ASU is fixed at the reporting date, except for obligations addressed within existing guidance in U.S. GAAP. ASU No. 2013-04 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2013, which for us means the first quarter of 2014. When adopted, ASU 2013-04 applies retroactively for existing joint and several liability arrangements within the scope of Subtopic 405-40. Although earlier application is permitted, we do not intend to adopt the ASU before the effective date. We do not expect this ASU to have a material impact on our financial position or results of operations, as we do not currently have any obligations within the scope of this ASU.
	In July 2013, the FASB issued ASU No. 2013-10, Inclusion of the Fed Funds Effective Swap Rate (or Overnight Index Swap Rate) as a Benchmark Interest Rate for Hedge Accounting Purposes (Topic 815), which permits for the inclusion of the Fed Funds Effective Swap Rate (OIS) as a U.S. benchmark interest rate for hedge accounting purposes, in addition to interest rates on direct Treasury obligations of the U.S. government (UST), and the London Interbank Offered Rate (LIBOR). The ASU amendments also remove the restriction on using different benchmark interest rates for similar hedges. ASU No. 2013-10 is effective prospectively for qualifying new or redesignated hedging relationships entered into on or after July 17, 2013. This ASU did not have a material impact on our financial position or results of operations.
	The FASB has not issued any other ASUs during 2013 or 2014 that we expect to be applicable and have a material impact on our future financial position or results of operations.
