BASIS OF PRESENTATION	'
	BASIS OF PRESENTATION
	Kennedy-Wilson Holdings, Inc.’s (together with its wholly owned and controlled subsidiaries, "we," "us," "our," "the Company" or “Kennedy Wilson”) unaudited interim consolidated 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. In the opinion of Kennedy Wilson, all adjustments, consisting of only normal and recurring items, necessary for a fair presentation of the results of operations for the three and nine months ended September 30, 2013 and 2012 have been included. The results of operations for these periods are not necessarily indicative of results that might be expected for the full year ending December 31, 2013. For further information, your attention is directed to the footnote disclosures found in Kennedy Wilson’s Annual Report on Form 10-K for the year ended December 31, 2012.
	The consolidated financial statements include the accounts of Kennedy Wilson and its wholly owned or controlled subsidiaries. All significant intercompany balances and transactions have been eliminated in consolidation. In addition, Kennedy Wilson evaluates its relationships with other entities to identify whether they are variable interest entities ("VIEs") as defined in the Financial Accounting Standards Board ("FASB") Accounting Standards Codification ("ASC") Subtopic 810-10 and to assess whether it is the primary beneficiary of such entities. If the determination is made that Kennedy Wilson is the primary beneficiary, then that entity is included in the consolidated financial statements in accordance with the ASC Subtopic 810-10. The ownership of the other interest holders in consolidated subsidiaries is reflected as noncontrolling interests.
	The preparation of the accompanying consolidated financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions about future events. These estimates and the underlying assumptions affect the amounts of assets and liabilities reported, disclosure about contingent assets and liabilities, and reported amounts of revenues and expenses. As future events and their effects cannot be determined with precision, actual results could differ significantly from these estimates.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES AND ADOPTION OF NEW ACCOUNTING PRONOUNCEMENTS	'
	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES AND ADOPTION OF NEW ACCOUNTING PRONOUNCEMENTS
	REVENUE RECOGNITION—Performance fees or carried interests are allocated to the general partner, special limited partner or asset manager of Kennedy Wilson's real estate funds and loan pool participations based on the cumulative performance of the funds and loan pools and are subject to preferred return thresholds of the limited partners and participants. At the end of each reporting period, Kennedy Wilson calculates the performance fee that would be due to the general partner, special limited partner or asset manager's interests for a fund or loan pool, pursuant to the fund agreement or participation agreements, as if the fair value of the underlying investments were realized as of such date, irrespective of whether such amounts have been realized. As the fair value of underlying investments varies between reporting periods, it is necessary to make adjustments to amounts recorded as performance fees to reflect either (a) positive performance resulting in an increase in the performance fee allocated to the general partner or asset manager or (b) negative performance that would cause the amount due to Kennedy Wilson to be less than the amount previously recognized as revenue, resulting in a negative adjustment to performance fees allocated to the general partner or asset manager. Substantially all of the performance fees are recognized in management and leasing fees, and substantially all of the carried interest is recognized in equity in joint venture income in our consolidated statements of operations. Total performance fees recognized through September 30, 2013 that may be reversed in future periods if there is negative fund or loan pool performance totaled $24.2 million. Performance fees accrued as of September 30, 2013 and December 31, 2012 were $24.2 million and $12.8 million, respectively, and are included in accounts receivable—related parties in the accompanying consolidated balance sheet.
	INVESTMENTS IN LOAN POOL PARTICIPATIONS AND NOTES RECEIVABLE—Interest income from investments in loan pool participations and notes receivable with declining credit quality are recognized on a level yield basis under the provisions of "Loans and Debt Securities Acquired with Deteriorated Credit Quality," ASC Subtopic 310-30, where a level yield model is utilized to determine a yield rate that, based upon projected future cash flows, accretes interest income over the estimated holding period. In the event that the present value of those future cash flows is less than net book value, a loss would be immediately recorded. When the future cash flows of a note cannot be reasonably estimated, cash payments are applied to the cost basis of the note until it is fully recovered before any interest income is recognized. Interest income from investments in notes receivable acquired at a discount are recognized using the effective interest method and interest income from notes receivable which the Company originates are recognized at the stated interest rate.
	DISTRIBUTIONS FROM UNCONSOLIDATED REAL ESTATE JOINT VENTURES—During the quarter ended March 31, 2013, the Company changed its method of accounting for determining the allocation of cash flows received from unconsolidated real estate joint ventures on its consolidated statement of cash flows from the "cumulative earnings" method to the "look-through" method, both of which are acceptable methods under GAAP.  Under the "look-through" approach, distributions are reported under operating cash flow unless the facts and circumstances of a specific distribution clearly indicate that it is a return of capital (e.g., a liquidating dividend or distribution of the proceeds from the joint venture's sale of assets), in which case it is reported as an investing activity.  The newly adopted method is preferable because it enables the Company to look to the nature and source of the distribution received and classify it appropriately between operating and investing activities on the statement of cash flows based upon the source, which allows the Company to present financial statements more consistent with accounting principles of consolidation.  The effects of the change upon the nine month period ended September 30, 2012 are as follows:
		Cumulative Earnings Method			Look-through Method
	Operating Cash Flows:
	Operating distributions from joint ventures	$	20,671,000		$	30,301,000
	Net cash provided from operating activities	2,835,000			12,465,000
	Investing Cash Flows:
	Investing distributions from joint ventures	37,246,000			27,616,000
	Net cash used in investing activities	(76,510,000		)	(86,140,000		)
	ACCOUNTS RECEIVABLE—Accounts receivable are recorded at the contractual amount as determined by the underlying agreements and do not bear interest. An allowance for doubtful accounts is provided when the Company determines there are probable credit losses in the Company’s existing accounts receivable based on historical experience. The Company reviews its accounts receivable for probable credit losses on a quarterly basis. As of September 30, 2013, the Company had an immaterial allowance for doubtful accounts and during the nine months ended September 30, 2013 and 2012 recorded no provision for doubtful accounts.
	FOREIGN CURRENCIES—The financial statements of subsidiaries located outside the United States are measured using the local currency as the functional currency. The assets and liabilities of these subsidiaries are translated at the rates of exchange at the balance sheet date, and income and expenses are translated at the average monthly rate. The foreign currencies include the euro, the British pound sterling, and the Japanese yen. Cumulative translation adjustments, to the extent not included in cumulative net income, are included in the consolidated statement of equity as a component of accumulated other comprehensive income.
	DERIVATIVE FINANCIAL INSTRUMENTS AND HEDGING ACTIVITIES—All derivative instruments are recognized as either assets or liabilities in the balance sheet at their respective fair values. For derivatives designated in hedging relationships, changes in fair value of cash flow hedges or net investment hedges are recognized in accumulated other comprehensive income, to the extent the derivative is effective at offsetting the changes in the item being hedged until the hedged item affects earnings. Changes in fair value for fair value hedges are recognized in earnings.
	RECENT ACCOUNTING PRONOUNCEMENTS— In February 2013, the FASB issued ASC Update No. 2013-02 "Comprehensive Income (Topic 220): Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income." Update No. 2013-02 is effective prospectively for reporting periods beginning after December 15, 2012. ASC 2013-02 requires an entity to present separately information about the effects on net income of significant amounts reclassified out of each component of accumulated other comprehensive income. An entity can present the information on the face of the comprehensive income statement or as a separate disclosure in the notes to the financial statements. Kennedy Wilson does not have any effect from adoption as it has already followed this presentation.
	The FASB did not issue any other ASCs during the first nine months of 2013 that we expect to be applicable and have a material impact on our financial position or results of operations.

	(1) The note receivables had a weighted average stated interest rate of 8.52% and 5.65% at September 30, 2013 and December 31, 2012 and maturity dates ranging from August 2014 to February 2017. Effective interest rates are higher as certain note receivables were acquired at a discount.
	During the nine months ended September 30, 2013, Kennedy Wilson sold a 50% interest in an entity that held a note receivable of $122.8 million secured by the shopping center and 107 residential units in the United Kingdom to an institutional investor. As a result of the sale and loss of control, Kennedy Wilson deconsolidated the investment and is accounting for it as an equity method investment.
	Interest Income from Notes Receivable
	Kennedy Wilson recognized interest income on note receivables of $0.3 million and $1.5 million during the three months ended September 30, 2013 and 2012 and $1.1 million and $2.0 million for the nine months ended September 30, 2013 and 2012.

	Acquisitions
	During the third quarter, the Company acquired a retail center for $5.6 million in Richfield, UT which was financed with a $4.0 million mortgage loan and equity.
	On June 27, 2013, the Company acquired a Class A office building in the golden triangle section of Beverly Hills, CA for $29.7 million which was financed with an $18.7 million mortgage loan and equity.
	On April 29, 2013, the Company acquired a 450-unit apartment building in Salt Lake City, UT for $61.8 million and financed it with a $49.7 million mortgage loan and equity.
	Joint Venture Consolidation
	On March 28, 2013, the Company acquired the interest of some of its existing partners in a 615-unit apartment building in Northern California, increasing its ownership from 15% to 94%.  The original 15% interest had a book value of $0 due to prior distributions. Cash consideration of $15.7 million was paid by the Company to increase its ownership in the property to 94%. As a result of obtaining control, the Company was required to consolidate the assets and liabilities at fair value in accordance with Business Combination guidance. Kennedy Wilson recorded an acquisition-related gain in the amount of $9.5 million in the accompanying consolidated statements of operations for the nine months ended September 30, 2013 as the fair value was in excess of the carrying value of its ownership interest.  As the transaction was between willing third party market participants, the purchase price was an approximation of fair value.  Accordingly, $1.3 million in cash and cash equivalents, $0.1 million in accounts receivable, $2.2 million in other assets (including $1.2 million of acquired in-place lease values), $120.1 million in real estate, net, $0.1 million in accounts payable, $3.1 million in accrued expenses and other liabilities, $93.5 million in mortgage loans payable, and $1.8 million in noncontrolling interest were recorded as a result of the consolidation.
	On September 30, 2013, the Company and one of its equity partners amended existing operating agreements governing investments in three retail centers in the Western U.S. in which the Company has on average an approximate 90% ownership interest and which were accounted for on the equity method. These amendments allowed the Company to gain control of the operating properties. As a result of obtaining control, the Company was required to consolidate the assets and liabilities at fair value in accordance with Business Combination guidance. Due to the consolidation, $26.5 million in real estate, net, $20.1 million in mortgage loans, $2.5 million in other assets (including $2.3 million of acquired in-place lease values), $1.4 million in cash and $0.8 million in noncontrolling interest were recorded as of September 30, 2013. The consolidation resulted in an acquisition-related gain of $1.7 million as the fair value of its ownership interest was in excess of the carrying value. Prior period amounts for these retail centers are still presented on an equity method basis.
	Pro forma results of operations
	The results of operations of the assets acquired have been included in our consolidated financial statements since the date of its acquisition. The unaudited pro forma data presented below assumes that the acquisitions occurred as of January 1, 2012.

	INVESTMENTS IN JOINT VENTURES
	Kennedy Wilson has a number of joint venture interests, generally ranging from 5% to approximately 50%, that were formed to acquire, manage, develop, and/or sell real estate and invest in loan pools and discounted loan portfolios. Kennedy Wilson has significant influence over these entities, but not control, and accordingly, these investments are accounted for under the equity method.
	Joint Venture Holdings
	As of September 30, 2013 and December 31, 2012, the Company's equity investment in joint ventures totaled $742.2 million and $543.2 million, respectively.
	The following table details our investments in joint ventures by investment type and geographic location as of September 30, 2013:
		Multifamily		Commercial			Loan			Residential			Other		Total

	KW Residential LLC
	The Company's largest joint venture investment, KW Residential, LLC ("KWR"), had a balance of $72.2 million and $102.7 million as of September 30, 2013 and December 31, 2012, respectively. KWR is a joint venture investment in a portfolio of 50 apartment buildings comprised of approximately 2,400 units, located primarily in Tokyo and surrounding areas. Kennedy Wilson owns approximately 41% of KWR.
	During the three and nine months ended September 30, 2013, Kennedy Wilson recognized $0.3 million and $6.6 million, respectively, in losses from foreign currency translation adjustments, net of hedges from its investment in KWR. For the three and nine months ended September 30, 2012, Kennedy Wilson recognized $0.6 million and $2.5 million, respectively, in gains from foreign currency translation adjustments, net of hedges from its investment in KWR.
	During the three and nine months ended September 30, 2013 and 2012, the Company received the following cash distributions from its investment in KWR for the settlement of hedges, refinancing of property level debt, and operating distributions:
		Three Months Ended September 30,							Nine Months Ended September 30,
		2013			2012				2013				2012
	Settlement of hedges	$	—		$	—			$	10,838,000			$	—

	Total	$	4,125,000		$	—			$	22,701,000			$	9,023,000
	The cash received as a result of unwinding KWR's hedges will not be realized in our statement of operations until the underlying investment is substantially liquidated.
	As of September 30, 2013, the Company did not have any other joint venture investments which individually exceeded 10% of the investments in the joint venture balance.
	Note Conversion into Real Estate
	During the second quarter of 2013, the Company and one of its equity partners foreclosed on a class A office building and an adjacent 3.5 acre site in Dublin, Ireland. As a result of the foreclosure, the joint venture was required to consolidate the assets and liabilities at fair value under ASC 805 - Business Combinations.  As the fair value of the assets was in excess of the basis in the previously held mortgage notes, the joint venture recognized a $30.1 million acquisition related gain. The Company's portion of the gain was $15.0 million and was recognized in equity in joint venture income.
	During the third quarter of 2013, the Company and one of its equity partners converted a mortgage note purchased in the fourth quarter 2012 by the Company and its equity partners into a 100% equity interest on "The Rock", a retail, residential and entertainment center in Manchester, United Kingdom. As a result of the conversion, the joint venture was required to consolidate the assets and liabilities at fair value. As the fair value of the assets were in excess of the basis in the previously held mortgage note, the joint venture recognized a $28.8 million acquisition-related gain. The Company's portion of the gain was $14.4 million and was recognized in equity in joint venture income.
	Retail Centers Consolidation
	On September 30, 2013, the Company and one of its equity partners amended existing operating agreements governing investments in three retail centers in the Western U.S. in which the Company has on average an approximate 90% ownership interest and which were accounted for on the equity method. As a result of obtaining control, the joint venture investments are now consolidated as of September 30, 2013 and not treated as investments in joint ventures. The investments are presented as an equity method investment for prior periods. See note 4.
	Contributions to Joint Ventures
	During the nine months ended September 30, 2013, Kennedy Wilson made $279.4 million in contributions to new and existing joint venture investments.
	See the table below for a breakdown of contributions to new joint venture investments for the nine months ended September 30, 2013:
		Multifamily				Commercial					Residential
		Amount		No. of Properties		Amount			No. of Properties		Amount			No. of Properties	Total
	Western U.S.	$	9,085,000	2		$	30,320,000		4		$	4,350,000		2	$	43,755,000
	United Kingdom	—		—		92,169,000			3		—			—	92,169,000
	Ireland	57,951,000		1		38,734,000			1		—			—	96,685,000

	In addition to the capital contributions above to new joint venture investments, during the same period, Kennedy Wilson contributed $46.8 million to existing joint ventures to pay off external debt, fund our share of a development project and for working capital needs.
	Equity in joint venture income is reduced by acquisition costs of $12.0 million during the nine months ended September 30, 2013.  These costs are the result of investing more than $130 million into new commercial project joint ventures, principally in the United Kingdom and Ireland which resulted in significant stamp duty taxes.
	Distributions from Joint Ventures
	The following table details cash distributions by investment type and geographic location for the nine months ended September 30, 2013:

	During the nine months ended September 30, 2013, Kennedy Wilson received $108.2 million in operating and investing distributions from its joint ventures. Investing distributions resulted from KWR's favorable settlement of Japanese yen-related hedges and refinancing a portion of its multifamily portfolio, the refinancing of property level debt, asset sales, and loan resolutions. Operating distributions resulted from operating cash flow generated by the joint venture investments.
	Variable Interest Entities
	Kennedy Wilson has determined that it has investments in five variable interest entities ("VIEs") as of September 30, 2013 and has concluded that Kennedy Wilson is not the primary beneficiary of any of the investments. As of September 30, 2013, the five VIEs had assets totaling $211.2 million with Kennedy Wilson’s exposure to loss as a result of its interests in these VIEs totaling $84.9 million related to its equity contributions.
	The Company determines the appropriate accounting method with respect to all investments that are not VIEs based on the control-based framework (controlled entities are consolidated) provided by the consolidations guidance in ASC Topic 810. The Company's determination considers specific factors cited under ASC 810-20 "Control of Partnerships and Similar Entities" which presumes that control is held by the general partner (and managing member equivalents in limited liability companies). Limited partners' substantive participation rights may overcome this presumption of control. The Company accounts for joint ventures it is deemed not to control using the equity method of accounting while controlled entities are consolidated.
	Capital Commitments
	As of September 30, 2013, Kennedy Wilson has unfulfilled capital commitments totaling $9.0 million to four of its joint ventures. We may be called upon to contribute additional capital to joint ventures in satisfaction of Kennedy Wilson capital commitment obligations.
Guarantees
Kennedy Wilson has certain guarantees associated with loans secured by consolidated assets or assets held directly or in various joint ventures. As of September 30, 2013 the maximum potential amount of future payments (undiscounted) Kennedy Wilson could be required to make under the guarantees was approximately $53.3 million which is approximately 1.7% of the property level debt of the Company. The guarantees expire through 2017, and Kennedy Wilson’s performance under the guarantees would be required to the extent there is a shortfall upon liquidation between the principal amount of the loan and the net sale proceeds from the property. Based upon Kennedy Wilson’s evaluation of guarantees under ASC Subtopic 460-10 "Estimated Fair Value of Guarantees," the estimated fair value of guarantees made as of September 30, 2013 and December 31, 2012 is immaterial.

	INVESTMENT IN LOAN POOL PARTICIPATION
	As of September 30, 2013 and December 31, 2012, the Company's investment in loan pool participations totaled $58.8 million and $95.6 million, respectively.
	The Company's largest loan pool based on initial unpaid principal balance ("UPB"), which is secured by real estate primarily located in the United Kingdom (the “UK Loan Pool”), had a balance of $11.4 million and $60.4 million as of September 30, 2013 and December 31, 2012, respectively. As of September 30, 2013, the UPB of the loans was $189.1 million due to loan resolutions of $1.9 billion, representing 91% of the pool. The Company expects to accrete $20.0 million in interest income on the UK Loan Pool over the total estimated collection period (excluding asset management fees) and has accreted $16.7 million to date.
	The following table represents the demographics of the Company's investment in the loan pools including the initial UPB and the UPB as of September 30, 2013.

	Short-term investments
	The carrying value of short-term investments approximates fair value due to the short-term maturities of these investments at December 31, 2012. The short-term investments matured during the second quarter of 2013.
	Investments in joint ventures
	Kennedy Wilson records its investments in KW Property Fund III, L.P., Kennedy Wilson Real Estate Fund IV, L.P., and SG KW Venture I, LLC (the "Funds") based upon the net assets that would be allocated to its interests in the Funds assuming the Funds were to liquidate their investments at fair value as of the reporting date. Kennedy Wilson’s investment balance in the Funds was $27.4 million and $25.8 million at September 30, 2013 and December 31, 2012, respectively, which is included in investments in joint ventures in the accompanying consolidated balance sheets. As of September 30, 2013, Kennedy Wilson had unfunded capital commitments to the Funds in the amount of $8.5 million.
	Kennedy Wilson elected to use the fair value option ("FV Option") for two investments in joint venture entities to more accurately reflect the timing of the value created in the underlying investments and report those results in current operations. Kennedy Wilson's investment balance in the FV Option investments was $46.8 million and $42.6 million at September 30, 2013 and December 31, 2012, respectively, which are included in investments in joint ventures in the accompanying balance sheets.
	The following table summarizes our investments in joint ventures held at fair value by type:
		30-Sep-13				31-Dec-12
	Funds	$	27,381,000			$	25,795,000

	Ending balance	$	74,183,000			$	50,995,000		$	74,183,000		$	50,995,000
	The change in unrealized and realized gains and losses is included in equity in joint venture income in the accompanying statements of operations.
	There was no material change in unrealized gains and losses on Level 3 investments during the three and nine months ended September 30, 2013 and 2012 for investments still held as of September 30, 2013.
	In estimating fair value of real estate held by the Funds and the two FV Option investments, Kennedy Wilson considers significant unobservable inputs such as capitalization and discount rates. The table below describes the range of unobservable inputs for real estate assets:
		Estimated Rates Used for
		Capitalization Rates		Discount Rates
	Multifamily	5.75% - 7.00%		7.50% - 9.00%
	Commercial	6.25% - 7.50%		7.00% - 9.75%
	Retail	6.00% - 10.00%		9.00% - 12.00%
	Land and condominium units	n/a		8.00% - 12.00%
	Loan	n/a		2.00% - 9.30%
	In valuing real estate, related assets and indebtedness, Kennedy Wilson considers significant inputs such as the term of the debt, value of collateral, market loan-to-value ratios, market interest rates and spreads, and credit quality of investment entities. The credit spreads used by Kennedy Wilson for these types of investments range from 2.00% to 9.30%.
	The accuracy of estimating fair value for investments utilizing unobservable inputs cannot be determined with precision and cannot be substantiated by comparison to quoted prices in active markets. As such, estimated fair value may not be realized in a current sale or immediate settlement of the asset or liability. Additionally, there are inherent uncertainties in any fair value measurement technique, and changes in the underlying assumptions used, including cap rates, discount rates, liquidity risks, and estimates of future cash flows, could significantly affect the fair value measurement amounts.
	Currency forward contracts
	Kennedy Wilson has currency forward contracts to manage its exposure to currency fluctuations between its functional currency (U.S. dollars) and the functional currency (euros and GBP) of certain of its wholly owned subsidiaries. To accomplish this objective, Kennedy Wilson hedged these exposures by entering into currency forward contracts to partially hedge Kennedy Wilson's exposure to its net investment in certain foreign operations caused by currency fluctuations. The currency forward contracts are valued based on the difference between the contract rate and the forward rate at maturity of the foreign currency applied to the notional value in that foreign currency discounted at a market rate for similar risks. Although Kennedy Wilson has determined that the majority of the inputs used to value its derivative fall within Level 2 of the fair value hierarchy, the counterparty risk adjustments associated with the derivative utilize Level 3 inputs. However, as of September 30, 2013, Kennedy Wilson assessed the significance of the impact of the counterparty valuation adjustments on the overall valuation of its derivative positions and determined that the counterparty valuation adjustments are not significant to the overall valuation of its derivative. As a result, Kennedy Wilson has determined that its derivative valuation in its entirety be classified in Level 2 of the fair value hierarchy.
	Changes in fair value are recorded in other comprehensive income in the accompanying consolidated statements of comprehensive income (loss) as the portion of the currency forward contract used to hedge currency exposure of its certain wholly owned subsidiaries qualifies as a net investment hedge under ASC Topic 815. The fair value of the derivative instruments held as of September 30, 2013 are included in accrued expenses and other liabilities on the balance sheet.
	The table below details the currency forward contracts Kennedy Wilson had as of September 30, 2013:
									Change in Unrealized Gains (Losses)
	Currency	Notional Amount	Trade Date	Settlement Date	Exchange Rate	Fair Value			Three Months Ended September 30, 2013			Nine Months Ended September 30, 2013
	Euro	€ 86,000,000	5/31/2012 - 7/11/2013	6/4/2015 - 7/15/2015	1.2400 - 1.3312	$	(5,157,000	)	$	(4,487,000	)	$	(3,466,000	)
	GBP	£25,500,000	8/9/2013 - 8/23/2013	2/13/2014 - 8/28/2014	1.5479 - 1.5522	(1,616,000		)	(1,616,000		)	(1,616,000		)
	Total					$	(6,773,000	)	$	(6,103,000	)	$	(5,082,000	)
	In order to manage currency fluctuations between the Company's functional currency (U.S. dollar) and the functional currency of KWR's functional currency (Japanese yen), the Company entered into forward foreign currency contracts to hedge a portion of its net investment in KWR. During the three and nine months ended September 30, 2013, the Company recognized an immaterial amount and $8.7 million, respectively, of gross unrealized gains related to these hedges.
	Fair value of financial instruments
	The carrying amounts of cash and cash equivalents, accounts receivable including related party receivables, accounts payable, accrued expenses and other liabilities, accrued salaries and benefits, and deferred and accrued income taxes approximate fair value due to their short-term maturities. The carrying value of notes receivable (excluding related party notes receivable as they are presumed not to be an arm’s length transaction) approximates fair value as the terms are similar to loans with similar characteristics available in the market.
	The Company accounts for its debt liabilities at face value plus net unamortized debt premiums. The fair value as of September 30, 2013 and December 31, 2012 for the senior notes payable, borrowings under lines of credit, mortgage loans payable and junior subordinated debentures were estimated to be approximately $822.2 million and $708.2 million, respectively, based on a comparison of the yield that would be required in a current transaction, taking into consideration the risk of the underlying collateral and our credit risk to the current yield of a similar security, compared to their carrying value of $789.6 million and $686.2 million at September 30, 2013 and December 31, 2012, respectively.

	The following table summarizes the changes in each component of accumulated other comprehensive income (loss), net of 40% estimated tax:
			Foreign Currency Translation			Forward Contract Foreign Currency			Total Accumulated Other Comprehensive Income
	Balance at December 31, 2012		$	10,800,000		$	1,769,000		$	12,569,000
	Unrealized (losses) gains, arising during the period		(15,362,000		)	3,665,000			(11,697,000		)
	Taxes on unrealized (losses) gains, arising during the period		6,146,000			(1,465,000		)	4,681,000
	Balance at September 30, 2013		$	1,584,000		$	3,969,000		$	5,553,000
	The local currencies for our interests in foreign operations include the euro, the British pound sterling, and the Japanese yen. The related amounts on our balance sheets are translated into U.S. dollars at the exchange rates at the respective financial statement date, while amounts on our statements of operations are translated at the average exchange rates during the respective period. The increase in the unrealized losses on foreign currency translation is a result of the strengthening of the U.S. dollar against the euro, the British pound and the Japanese yen during the nine months ended September 30, 2013.
	In order to manage currency fluctuations, the Company entered into forward foreign currency contracts to hedge a portion of its Japanese yen-based investments. During the nine months ended September 30, 2013, the Company recognized a gross unrealized gain of $8.7 million related to these hedges. Additionally, during the year, KWR settled several Japanese yen-related hedges resulting in cash proceeds of $23.1 million, of which Kennedy Wilson received $10.8 million. The cash received as a result of unwinding these hedges will not be realized in our statement of operations until the underlying investment is substantially liquidated. Kennedy Wilson also has a currency forward contract to manage its exposure to currency fluctuations between its functional currency (U.S. dollars) and the functional currency (euros and GBP) of certain of its wholly-owned subsidiaries (see note 7 for more detail). During the nine months ended September 30, 2013, the Company recognized a gross unrealized loss of $5.1 million related to these hedges.

Income Tax Disclosure [Abstract]	'
INCOME TAXES	'
	INCOME TAXES
	In determining quarterly provisions for income taxes, Kennedy Wilson uses an effective tax rate based on actual year-to-date income and statutory tax rates. The effective tax rate also reflects Kennedy Wilson's assessment of its potential exposure for uncertain tax positions.
	The fluctuations between periods in the Company's effective tax rate are mainly due to varying levels of income and amounts attributable to foreign sourced income and noncontrolling interests. Permanent differences that impact the Company's effective rate as compared to the U.S. federal statutory rate of 34% were not materially different in amount for all periods. The difference between the U.S. federal rate of 34% and the Company's effective rate is attributable to the taxation of foreign sourced income being taxed at rates lower than the U.S. domestic rate and income attributable to noncontrolling interests. The Company's subsidiaries in Ireland and the United Kingdom are subject to corporate tax rates of 12.5% and 23%, respectively.

Summary of Significant Accounting Policies and Adoption of New Accounting Pronouncements (Policies)	9 Months Ended
	Sep. 30, 2013
Accounting Policies [Abstract]	'
REVENUE RECOGNITION	'
	REVENUE RECOGNITION—Performance fees or carried interests are allocated to the general partner, special limited partner or asset manager of Kennedy Wilson's real estate funds and loan pool participations based on the cumulative performance of the funds and loan pools and are subject to preferred return thresholds of the limited partners and participants. At the end of each reporting period, Kennedy Wilson calculates the performance fee that would be due to the general partner, special limited partner or asset manager's interests for a fund or loan pool, pursuant to the fund agreement or participation agreements, as if the fair value of the underlying investments were realized as of such date, irrespective of whether such amounts have been realized. As the fair value of underlying investments varies between reporting periods, it is necessary to make adjustments to amounts recorded as performance fees to reflect either (a) positive performance resulting in an increase in the performance fee allocated to the general partner or asset manager or (b) negative performance that would cause the amount due to Kennedy Wilson to be less than the amount previously recognized as revenue, resulting in a negative adjustment to performance fees allocated to the general partner or asset manager. Substantially all of the performance fees are recognized in management and leasing fees, and substantially all of the carried interest is recognized in equity in joint venture income in our consolidated statements of operations. Total performance fees recognized through September 30, 2013 that may be reversed in future periods if there is negative fund or loan pool performance totaled $24.2 million. Performance fees accrued as of September 30, 2013 and December 31, 2012 were $24.2 million and $12.8 million, respectively, and are included in accounts receivable—related parties in the accompanying consolidated balance sheet.
INVESTMENTS IN LOAN POOL PARTICIPATIONS AND NOTES RECEIVABLE	'
	INVESTMENTS IN LOAN POOL PARTICIPATIONS AND NOTES RECEIVABLE—Interest income from investments in loan pool participations and notes receivable with declining credit quality are recognized on a level yield basis under the provisions of "Loans and Debt Securities Acquired with Deteriorated Credit Quality," ASC Subtopic 310-30, where a level yield model is utilized to determine a yield rate that, based upon projected future cash flows, accretes interest income over the estimated holding period. In the event that the present value of those future cash flows is less than net book value, a loss would be immediately recorded. When the future cash flows of a note cannot be reasonably estimated, cash payments are applied to the cost basis of the note until it is fully recovered before any interest income is recognized. Interest income from investments in notes receivable acquired at a discount are recognized using the effective interest method and interest income from notes receivable which the Company originates are recognized at the stated interest rate.
DISTRIBUTIONS FROM UNCONSOLIDATED REAL ESTATE JOINT VENTURES	'
	DISTRIBUTIONS FROM UNCONSOLIDATED REAL ESTATE JOINT VENTURES—During the quarter ended March 31, 2013, the Company changed its method of accounting for determining the allocation of cash flows received from unconsolidated real estate joint ventures on its consolidated statement of cash flows from the "cumulative earnings" method to the "look-through" method, both of which are acceptable methods under GAAP.  Under the "look-through" approach, distributions are reported under operating cash flow unless the facts and circumstances of a specific distribution clearly indicate that it is a return of capital (e.g., a liquidating dividend or distribution of the proceeds from the joint venture's sale of assets), in which case it is reported as an investing activity.  The newly adopted method is preferable because it enables the Company to look to the nature and source of the distribution received and classify it appropriately between operating and investing activities on the statement of cash flows based upon the source, which allows the Company to present financial statements more consistent with accounting principles of consolidation.
ACCOUNTS RECEIVABLE	'
	ACCOUNTS RECEIVABLE—Accounts receivable are recorded at the contractual amount as determined by the underlying agreements and do not bear interest. An allowance for doubtful accounts is provided when the Company determines there are probable credit losses in the Company’s existing accounts receivable based on historical experience. The Company reviews its accounts receivable for probable credit losses on a quarterly basis. As of September 30, 2013, the Company had an immaterial allowance for doubtful accounts and during the nine months ended September 30, 2013 and 2012 recorded no provision for doubtful accounts.
FOREIGN CURRENCIES	'
	FOREIGN CURRENCIES—The financial statements of subsidiaries located outside the United States are measured using the local currency as the functional currency. The assets and liabilities of these subsidiaries are translated at the rates of exchange at the balance sheet date, and income and expenses are translated at the average monthly rate. The foreign currencies include the euro, the British pound sterling, and the Japanese yen. Cumulative translation adjustments, to the extent not included in cumulative net income, are included in the consolidated statement of equity as a component of accumulated other comprehensive income.
DERIVATIVE FINANCIAL INSTRUMENTS AND HEDING ACTIVITIES	'
	DERIVATIVE FINANCIAL INSTRUMENTS AND HEDGING ACTIVITIES—All derivative instruments are recognized as either assets or liabilities in the balance sheet at their respective fair values. For derivatives designated in hedging relationships, changes in fair value of cash flow hedges or net investment hedges are recognized in accumulated other comprehensive income, to the extent the derivative is effective at offsetting the changes in the item being hedged until the hedged item affects earnings. Changes in fair value for fair value hedges are recognized in earnings.
