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 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 September 30, 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 September 30, 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 accompanying consolidated financial statements as of September 30, 2013 and December 31, 2012 and for the three and nine months ended September 30, 2013 and 2012 are the consolidated financial statements of Douglas Emmett, Inc. and our 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.
	The accompanying unaudited interim financial statements have been prepared pursuant to the rules and regulations of the U.S. Securities and Exchange Commission (SEC).  Certain information and footnote disclosures normally included in the financial statements prepared in accordance with accounting principles generally accepted in the United States (GAAP) may have been condensed or omitted pursuant to SEC rules and regulations, although we believe that the disclosures are adequate to make their presentation not misleading.  The accompanying unaudited financial statements include, in our opinion, all adjustments, consisting of normal recurring adjustments, necessary to present fairly the financial information set forth therein.  The results of operations for the interim periods are not necessarily indicative of the results that may be expected for the year ended December 31, 2013.  The interim financial statements should be read in conjunction with the consolidated financial statements in our 2012 Annual Report on Form 10-K and the notes thereto.  Any references to the number of properties and square footage are unaudited and outside the scope of our independent registered public accounting firm’s review of our financial statements in accordance with the standards of the United States Public Company Accounting Oversight Board.
	The preparation of financial statements in conformity with GAAP requires us to make certain estimates and assumptions, including, for example, with respect to the allocation of the purchase price of acquisitions among land, buildings, improvements, equipment and any related intangible assets and liabilities.  These estimates and assumptions are subjective and affect the reported amounts in the consolidated financial statements and accompanying notes.  Actual results could differ materially from those estimates.

Summary Of Significant Accounting Policies	'
	Summary of Significant Accounting Policies
	During the period covered by this report, we have not made any material changes to our significant accounting policies included in our 2012 Annual Report on Form 10-K.
	Income Taxes
	We have elected to be taxed as a REIT under the Internal Revenue Code of 1986, as amended. Provided that 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. We are subject to corporate-level tax on the earnings that we derive through our taxable REIT subsidiaries (TRS).
	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. We do not expect this ASU to have a material impact on our financial position or results of operations.
	The FASB has not issued any other ASUs during 2013 that we expect to be applicable and have a material impact on our future financial position or results of operations.

On August 15, 2013, we purchased a 191,000 square foot Class A office building located at 16501 Ventura Blvd. in Encino for a contract price of $61.0 million, or approximately $319 per square foot.

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 September 30, 2013, the totals of our existing swaps and caps 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
	Non-designated Hedges
	Derivatives not designated as hedges are not speculative. As of September 30, 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 September 30, 2013 and December 31, 2012, the fair value of derivatives in a net liability position, when aggregated by counterparty, was $75.3 million and $107.4 million, respectively, which includes accrued interest but excludes any adjustment for nonperformance risk related to these agreements.
	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 including depreciation, from unconsolidated real estate funds as interest payments are made by our Funds on their hedged items or transactions. We estimate that $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 $846 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. Changes in fair value of derivatives not designated as hedges are recognized as interest expense.

	Fair Value Measurement
	We record all derivatives on the balance sheet at fair value using the framework for measuring fair value established by the FASB.  The fair value of these hedges is obtained through independent third-party valuation sources that use conventional valuation algorithms. All of our derivative contracts are subject to enforceable master netting arrangements, and we have elected to present the fair value of our derivatives on a gross basis. See Note 11 for our fair value disclosures.

	Noncontrolling Interests
	Noncontrolling interests in our operating partnership relate to interests that are not owned by us.  Noncontrolling interests represented approximately 17% of our operating partnership at September 30, 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.

Fair Value of Financial Instruments	'
	Fair Value of Financial Instruments
	Our estimates of the fair value of financial instruments at September 30, 2013 were determined using available market information and appropriate valuation methods.  Considerable judgment is necessary to interpret market data and develop an 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, rents and other receivables, interest payable, accounts payable and accrued liabilities, security deposits, and dividends payable approximate their fair values 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 adjusting their face value for 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 September 30, 2013, the aggregate fair value of our secured notes payable was estimated to be approximately $3.40 billion, based on a credit-adjusted present value of the future principal and interest payments related to our debt, compared to their carrying value of $3.35 billion.  As of December 31, 2012, the estimated fair value of our secured loans was 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 September 30, 2013.
	The table below (in thousands) presents the derivative assets and 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:

	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 to date 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 September 30, 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 September 30, 2013 the maximum future payments under the swap agreement were approximately $7.1 million.  As of September 30, 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
	For the three and nine months ended September 30, 2013 and 2012, no tenant accounted for more than 10% of our total rental revenue and tenant recoveries.

Segment Reporting	'
	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.

	We manage and own equity interests in two Funds, Douglas Emmett Fund X, LLC (Fund X), and Douglas Emmett Partnership X, LP (Partnership X), through which institutional investors own 8 buildings totaling 1.8 million square feet in our core markets.  On a weighted average square footage basis, we own almost 60% of these Funds.
	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 a 16.3% interest in Fund X from existing investors for approximately $33.4 million in cash.
	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 the related party's interest in Fund X.
	The table below (in thousands) presents selected financial information for the Funds.  The amounts represent 100% (not our pro-rata share) of amounts related to the Funds, and are based upon historical acquired book value:

	In October 2013, there was a fire in a unit in one building at our Barrington Plaza apartment property. With the exception of two floors damaged by the fire (mostly from water and smoke), we reopened all of that building within a few days. We currently expect that the remaining 20 units will be fully restored within a few months, and we do not currently expect a material impact after application of available insurance proceeds.

	Income Taxes
	We have elected to be taxed as a REIT under the Internal Revenue Code of 1986, as amended. Provided that 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. We are subject to corporate-level tax on the earnings that we derive through our taxable REIT subsidiaries (TRS).
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. We do not expect this ASU to have a material impact on our financial position or results of operations.
	The FASB has not issued any other ASUs during 2013 that we expect to be applicable and have a material impact on our future financial position or results of operations.
