Amendment Description	'Kennedy-Wilson Holdings, Inc., a Delaware corporation (the “Company”) is re-issuing the historical financial statements and Management Discussion and Analysis of Financial Condition and Results of Operations included in its Annual Report on Form 10-K for the year ended December 31, 2012, which was originally filed with the Securities and Exchange Commission (the “SEC”) on March 12, 2013 (the “Original Report”) and amended pursuant to Amendment No. 1 to the Original Report, which was filed with the SEC on April 1, 2013 (such amendment, together with the Original Report, the “Amended Original Report”), to reflect a change in the Company’s 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 methods are acceptable methods under generally accepted accounting principles.  The change in accounting method affects only the consolidated statements of cash flows for the years ended December 31, 2012 and 2011.  The change for the year ended December 31, 2010 was immaterial.  See “Note 2-Distribution From Unconsolidated Real Estate Joint Ventures” to the Company’s consolidated financial statements filed as an exhibit to this Current Report on Form 8-K. As a result of the changes discussed above, the Company is updating and restating “Item 7- Management’s Discussion and Analysis of Financial Condition and Results of Operations,” and “Item 8 - Financial Statements and Supplementary Data.”  All other information contained in the Amended Original Report has not been updated or modified.  Unless specifically noted otherwise, the restated sections of the Amended Original Report filed as exhibits hereto continue to speak as of the date of the Original Report, and the Company has not updated the disclosure contained in such restated sections or the Amended Original Report to reflect events that have occurred since the filing of the Original Report.  Accordingly, this Current Report on Form 8-K and the restated sections filed as exhibits hereto should be read in conjunction with the Company’s other filings with the SEC since the filing of the Original Report.Â	'	'

BASIS OF PRESENTATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

BASIS OF PRESENTATION—The consolidated financial statements include the accounts of Kennedy Wilson and its wholly owned 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 (VIE) as defined by FASB Accounting Standards Codification (ASC) Subtopic 810 – Consolidation and to assess whether it is the primary beneficiary of such entities. In determining whether Kennedy Wilson is the primary beneficiary of a VIE, qualitative and quantitative factors are considered, including, but not limited to: the amount and characteristics of Kennedy-Wilson's investment; the obligation or likelihood for Kennedy Wilson to provide financial support; Kennedy Wilson's ability to control or significantly influence key decisions for the VIE; and the similarity with and significance to the business activities of Kennedy Wilson. Significant judgments related to these determinations include estimates about the future fair values and performance of real estate held by these VIEs and general market conditions. As of December 31, 2012, Kennedy-Wilson has determined that it does not have any VIEs except as discussed in the joint ventures policy below.

USE OF ESTIMATES—The preparation of the accompanying consolidated financial statements in conformity with U.S. generally accepted accounting principles (GAAP) 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. Management evaluates its estimates and assumptions on an ongoing basis using historical experience and other factors, including the current economic environment, which management believes to be reasonable under the circumstances. Management adjusts such estimates and assumptions when facts and circumstances dictate. The after-effects of the recent global financial crisis, including highly volatile credit, equity and foreign currency markets and a slow and uneven global economic recovery, have increased the uncertainty inherent in such estimates and assumptions. As future events and their effects cannot be determined with precision, actual results could differ significantly from these estimates. Changes in those estimates will be reflected in the financial statements in future periods.

REVENUE RECOGNITION—Revenue primarily consists of management fees, performance fees, commission revenue, rental income and sales of real estate.

Management fees are primarily comprised of property management fees and base asset management fees. Property management fees are earned for managing the operations of real estate assets and are generally based on a fixed percentage of the revenues generated from the respective real estate assets. Base asset management fees are earned from limited partners of funds Kennedy-Wilson sponsors and are generally based on a fixed percentage of committed capital or net asset value. These fees are recognized as revenue ratably over the period that the respective services are performed.

Performance fees or carried interest 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 fund 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 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 performances fees recognized to date through December 31, 2012 that may be reversed in future periods if there is negative fund performance totaled $12.8 million. Performance fees accrued as of December 31, 2012 and 2011 were $8.6 million and $4.2 million, respectively, and are included in accounts receivable—related parties in the accompanying consolidated balance sheet.

Commissions primarily consist of acquisition fees, auction and real estate sales commissions and leasing commissions. Acquisition fees are earned for identifying and closing investments on behalf of investors and are based on a fixed percentage of the acquisition price. Acquisition fees are recognized upon the successful completion of an acquisition after all required services have been performed. In the case of auction and real estate sales commissions, the revenue is generally recognized when escrow closes. In accordance with the guidelines established for Reporting Revenue Gross as a Principal versus Net as an Agent in the ASC Subtopic 605-45, Kennedy Wilson records commission revenues and expenses on a gross basis. Of the criteria listed in the Subtopic 605-45, Kennedy Wilson is the primary obligor in the transaction, does not have inventory risk, performs all or part of the service, has credit risk, and has wide latitude in establishing the price of services rendered and discretion in selection of agents and determination of service specifications. Leasing fees that are payable upon tenant occupancy, payment of rent or other events beyond Kennedy Wilson's control are recognized upon the occurrence of such events.

Rental income from operating leases is generally recognized on a straight-line basis over the terms of the leases.

Sales of real estate are recognized at the close of escrow when title to the real property passes to the buyer and there is no continuing involvement in the real property. Kennedy Wilson follows the requirements for profit recognition as set forth by the Sale of Real Estate ASC Subtopic 360-20.

REAL ESTATE ACQUISITIONS—When acquiring a property, the purchase price of acquired properties is recorded to land, buildings and building improvements and intangible lease value (value of above-market and below-market leases, acquired in-place lease values, and tenant relationships, if any) based on their respective estimated fair values in accordance with Business Combinations ASC Subtopics 805-10. Acquisition-related costs are expensed as incurred.

The valuations of real estate are based on management estimates of the real estate assets using income and market approaches. The indebtedness securing the real estate are valued, in part, based on third party valuations and management estimates also using an income approach.

INVESTMENTS IN JOINT VENTURES—Kennedy Wilson has a number of joint venture interests, that were formed to acquire, manage, and/or sell real estate and invest in loan pools and discounted loan portfolios. Investments in joint ventures which Kennedy Wilson does not control are accounted for under the equity method of accounting as Kennedy Wilson can exercise significant influence, but does not have the ability to control the joint venture. An investment in a joint venture is recorded at its initial investment and is increased or decreased by Kennedy Wilson’s share of income or loss, plus additional contributions and less distributions. A decline in the value of an investments in a joint venture that is other than temporary is recognized when evidence indicates that such a decline has occurred in accordance with Equity Method Investments ASC Subtopic 323-10. As of December 31, 2012, Kennedy Wilson also had investments in five joint venture investments which are VIEs in which Kennedy Wilson is not the primary beneficiary and therefore accounts for them under the equity method as well.

Profits on the sale of real estate held by joint ventures in which Kennedy Wilson has continuing involvement are deferred until such time that the continuing involvement has been concluded and all the risks and rewards of ownership have passed to the buyer. Profit on sales to joint ventures in which Kennedy Wilson retains an equity ownership interest results in partial sales treatment in accordance with Sale of Real Estate ASC Subtopic 360-20, thus deferring a portion of the gain as a result of Kennedy Wilson’s continuing ownership percentage in the joint ventures.

Kennedy Wilson has three investments in joint ventures, KW Property Fund III, L.P. (KW Fund III), Kennedy Wilson Real Estate Fund IV, L.P. (Fund IV) and SG KW Venture I, LLC (the Funds) that are investment companies under the Investment Companies ASC Subtopic 946-10. Thus, the Funds reflect their investments at fair value, with unrealized gains and losses resulting from changes in fair value reflected in their earnings. Kennedy Wilson has retained the specialized accounting for the Funds pursuant to Retention of Specialized Accounting for Investments in Consolidation ASC Subtopic 810-10 in recording its equity in joint venture income from the Funds.

Additionally, Kennedy Wilson elected the fair value option for two investments in joint venture entities that were acquired during 2008. Kennedy-Wilson elected to record these investments at fair value to more accurately reflect the timing of the value created in the underlying investments and report those results in current operations.

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 years ended December 31, 2012 and 2011are shown in the table below. The change for the year ended December 31, 2010 was immaterial.

INVESTMENTS IN LOAN POOL PARTICIPATIONS AND NOTES RECEIVABLE—Interest income from investments in loan pool participations and note receivable 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 which, 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. Interest income from investments in notes receivable which the Company originates are recognized at the stated interest rate.

FAIR VALUE MEASUREMENTS—Kennedy Wilson accounts for fair value measurements of financial assets and financial liabilities and for fair value measurements of nonfinancial items that are recognized or disclosed at fair value in the financial statements on a recurring basis under the provisions of Fair Value Measurements ASC Subtopic 820-10. Subtopic 820-10 defines fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. When estimating fair value in the absence of an orderly transaction between market participants, valuations of real estate are based on management estimates of the real estate assets using income and market approaches. The indebtedness securing the real estate and the investments in debt securities are valued, in part, based on third party valuations and management estimates also using an income approach.

GOODWILL—Goodwill results from the difference between the purchase price and the fair value of net assets acquired based upon the purchase method of accounting for business combinations. In accordance with Accounting for Goodwill ASC Subtopic 350-20, goodwill is reviewed for impairment on an annual basis. In testing for impairment, goodwill is assigned to the reporting unit based upon the amount of goodwill generated at the time of acquisition of the businesses by the reporting unit. The Company first perform a qualitative assessment annually at each reporting unit that has goodwill to determine if facts and circumstances indicate that goodwill is more likely than not impaired. If the qualitative assessment indicates that goodwill of a reporting unit is not more likely than not impaired, we do not perform a quantitative impairment test for the reporting unit. If the qualitative assessment indicates that goodwill of a reporting unit is more likely than not impaired, we perform the first step, or step 1, of the quantitative goodwill impairment test. The Company performs its annual review of impairment at year end and when a triggering event occurs between annual year end reviews. As a result of the evaluation performed as described above, Kennedy Wilson has determined that there was no impairment of goodwill as of December 31, 2012, 2011 and 2010.

CASH AND CASH EQUIVALENTS—Cash and cash equivalents consist of cash and all highly liquid investments purchased with maturities of three months or less. Cash and cash equivalents are invested in institutions insured by government agencies. Certain accounts contain balances in excess of the insured limits. Kennedy Wilson's operations and financial position are affected by fluctuations in currency exchange rates between the Yen and European currencies against the U.S. Dollar.

SHORT TERM INVESTMENTS—Short term investments, which have an original maturity of one year or less, are carried at amortized cost, which approximates fair value.

LONG-LIVED ASSETS—Kennedy-Wilson reviews its long-lived assets (excluding goodwill) whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable in accordance with Impairment of Long-Lived Assets ASC Subtopic 360-10. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to estimated undiscounted future cash flows expected to be generated by the asset. If the carrying amount of an asset exceeds its estimated undiscounted future cash flows, an impairment charge is recognized in the amount by which the carrying amount of the asset exceeds the fair value of the asset. Assets to be disposed of are presented separately in the balance sheet and reported at the lower of the carrying amount or fair value less costs to sell, and are no longer depreciated. The assets and liabilities of the assets to be disposed of are classified as held for sale and would be presented separately in the appropriate asset and liability sections of the balance sheet.

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 and is determined based on historical experience. The Company reviews its accounts receivable for probable credit losses on a quarterly basis. As of December 31, 2012, the Company had an immaterial allowance for doubtful accounts and during the years ended December 31, 2012, 2011 and 2010 had recorded no provision for doubtful accounts.

FAIR VALUE OF FINANCIAL INSTRUMENTS—The estimated fair value of financial instruments is determined using available market information and appropriate valuation methodologies. Considerable judgment, however, is necessary to interpret market data and develop the related estimates of fair value. Accordingly, the estimates presented herein are not necessarily indicative of the amounts that could be realized upon disposition of the financial instruments. The use of different market assumptions or estimation methodologies may have a material impact on the estimated fair value amounts.

NONCONTROLLING INTERESTS—Noncontrolling interests are reported within equity as a separate component of Kennedy-Wilson's equity in accordance with Noncontrolling Interests in Consolidated Financial Statements ASC Subtopic 810-10. Revenues, expenses, gains, losses, net income or loss, and other comprehensive income are reported in the consolidated statements of operations at the consolidated amounts and net income and comprehensive income attributable to noncontrolling interests are separately stated.

CAPITALIZED INTEREST—Kennedy-Wilson capitalizes interest in accordance with Capitalization of Interest Cost ASC Subtopic 835-20 for assets that are undergoing development or entitlement activities in preparation for their planned principal operations. For qualifying equity investments, interest is capitalized in accordance with Capitalization of Interest Cost in Financial Statements That Include Investments Accounted for Under the Equity Method ASC Subtopic 835-20. An appropriate interest rate is applied to Kennedy-Wilson’s cash investment in the qualifying asset. Interest capitalization begins upon the commencement of development activities and ceases when the investment has begun its planned principal operations.

DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES—Kennedy Wilson has joint ventures that hold derivatives to reduce their exposure to foreign currencies. 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.

GUARANTEES—Kennedy-Wilson has certain guarantees associated with loans secured by assets held in various joint venture investments. The maximum potential amount of future payments (undiscounted) Kennedy Wilson could be required to make under the guarantees was $55.5 million and $26.7 million at December 31, 2012 and 2011, respectively. The guarantees expire through 2017 and Kennedy Wilson’s performance under the guarantees would be required to the extent there is a shortfall in liquidation between the principal amount of the loan and the net sales proceeds of the asset. Based upon Kennedy Wilson’s evaluation of guarantees under Estimated Fair Value of Guarantees ASC Subtopic 460-10, the estimated fair value of guarantees made as of December 31, 2012 and 2011 is immaterial.

CONCENTRATION OF CREDIT RISK—Financial instruments that subject Kennedy Wilson to credit risk consist primarily of accounts and notes receivable and cash equivalents. Credit risk is generally diversified due to the large number of entities composing Kennedy Wilson’s customer base and their geographic dispersion throughout the United States, the United Kingdom, Ireland and Japan. Kennedy Wilson performs ongoing credit evaluations of its customers and debtors.

EARNINGS PER SHARE—Basic earnings per share is computed based upon the weighted average number of shares of common stock outstanding during the periods presented. Diluted earnings per share is computed based upon the weighted average number of shares of common stock and potentially dilutive securities outstanding during the periods presented. The dilutive impact of potentially dilutive securities including warrants, convertible securities, and unvested stock which were outstanding during the period is calculated by the “treasury stock” method.

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 statements of equity and comprehensive income as a component of accumulated other comprehensive income.

COMPREHENSIVE (LOSS) INCOME—Comprehensive (loss) income consists of net income (loss) and other comprehensive income (loss). In the accompanying consolidated balance sheets, accumulated other comprehensive income consists of foreign currency translation adjustments and unrealized gains (losses) on available for sale securities and derivative instruments.

REPURCHASE OF EQUITY INSTRUMENTS—Upon the decision to retire repurchased equity instruments, Kennedy Wilson records the retirement as a reduction to additional paid in capital.

SHARE-BASED PAYMENT ARRANGEMENTS—Kennedy Wilson accounts for its share-based payment arrangements under the provisions of Share-Based Payments ASC Subtopic 718-10. Compensation cost for employee service received in exchange for an award of equity instruments is based on the grant-date fair value of the share-based award that is ultimately settled in equity of Kennedy Wilson. The cost of employee services is recognized over the period during which an employee provides service in exchange for the share-based payment award. Share-based payment arrangements with only services conditions that vest ratably over the requisite service period are recognized on the straight-line basis and performance awards that vest ratably are recognized on a tranche by tranche basis over the performance period. Unrecognized compensation costs for share-based payment arrangements that have been modified are recognized over the original service or performance period.

FAIR VALUE OPTION—Kennedy-Wilson accounts for financial assets and financial liabilities at fair value on an instrument-by-instrument basis, with changes in fair value reported in earnings in accordance with the provisions of Fair Value Measurements and Disclosures ASC Subtopic 820-10.

INCOME TAXES—Income taxes are accounted for under the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and operating loss and tax credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. In accordance with Accounting for Uncertainty in Income Taxes ASC Subtopic 740-10, Kennedy-Wilson recognizes the effect of income tax positions only if those positions are more likely than not of being sustained. Recognized income tax positions are measured at the largest amount that is greater than 50% likely of being realized. Changes in recognition or measurement are reflected in the period in which the change in judgment occurs.

Kennedy-Wilson records interest related to unrecognized tax benefits in interest expense and penalties in selling, general, and administrative expenses.

RECENT ACCOUNTING PRONOUNCEMENTS—In May 2011, the FASB issued Accounting Standards Codification (ASC) Update No. 2011-04, Fair Value Measurement - Amendments to Achieve Common Fair Value Measurements and Disclosure Requirements in US GAAP and IRFS. Update No. 2011-04 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2011. Update 2011-04 is intended to result in common fair value measurement and disclosure requirements in U.S. GAAP and IFRS. Consequently, the amendments change the wording used to describe many of the requirements in U.S. GAAP for measuring fair value and for disclosing information about fair value measurements. The adoption of this update did not have a material impact to our financial statements.

In June 2011, the FASB issued Accounting Standards Codification (ASC) Update No. 2011-05, Comprehensive Income (Topic 220): Presentation of Comprehensive Income. Update No. 2011-05 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2011. Update 2011-05 requires an entity to present each component of net income along with total net income, each component of other comprehensive income along with a total for other comprehensive income, and a total amount for comprehensive income. The Company has adopted this approach and the required disclosure is presented herein.

In September 2011, the FASB issued Accounting Standards Codification (ASC) Update No. 2011-08, Intangibles-Goodwill and Other (Topic 350): Testing Goodwill for Impairment, which is intended to simplify goodwill impairment testing. Entities will be permitted to perform a qualitative assessment on goodwill impairment to determine whether it is more likely than not (defined as having a likelihood of more than 50 percent) that the fair value of a reporting unit is less than its carrying amount as a basis for determining whether it is necessary to perform the two-step goodwill impairment test. This guidance is effective for goodwill impairment tests performed in interim and annual periods for fiscal years beginning after December 15, 2011. The adoption of this update did not have a material impact on our financial statements.

	REAL ESTATE
	The following table summarizes Kennedy Wilson's investment in consolidated real estate properties at December 31, 2012 and 2011:
		December 31,
		2012			2011
	Land	$	99,595,000		$	65,908,000
	Buildings	193,302,000			53,112,000
	Building improvements	3,964,000			2,295,000
		296,861,000			121,315,000

	Real estate, net	$	289,449,000		$	115,880,000
	Real property, including land, buildings, and building improvements, are included in real estate and are generally stated at cost.  Buildings and building improvements are depreciated on the straight-line method over their estimated lives not to exceed 40 years.
	Depreciation expense on buildings and and building improvements for the years ended December 31, 2012, 2011 and 2010 was $2.0 million, $1.4 million and $1.3 million, respectively.
	2012 Consolidated Acquisitions
	During 2012, the Company acquired three apartment buildings: a 178-unit apartment building in Oakland, California, for $31.0 million, a 366 unit apartment building in Salt Lake City, Utah, for $43.5 million, and a 217-unit apartment building in Renton, Washington, for $44.4 million. In addition, Kennedy Wilson acquired one office building in North Hollywood, California, consisting of approximately 175,000 square feet for $48.0 million.
	The purchase price of acquired properties is recorded to land, buildings and building improvements and intangible lease value (value of above-market and below-market leases, acquired in-place lease values, and tenant relationships, if any) based on their respective estimated fair values in accordance with Business Combinations ASC Subtopics 805-10. Acquisition-related costs are expensed as incurred. The fair value was in excess of the purchase price for the acquisition of the Renton apartment building, which was an off-market transaction, and therefore we recognized a gain of approximately $2.6 million in the accompanying consolidated statements of operations for the year ended December 31, 2012. In addition, the Company incurred and expensed acquisition related costs of $0.7 million for the year ended December 31, 2012.
	The Company considers its allocation of the purchase price of properties acquired in 2012 to be preliminary, particularly with respect to the valuation of in-place lease values and the allocation of value between land and buildings. The following table summarizes Kennedy Wilson's acquisitions during 2012 as described above:
	Land	$	32,433,000
	Buildings	125,683,000
	Acquired in-place lease values	8,180,000
	Total purchase price	166,296,000
	Mortgage notes placed/assumed	(110,029,000		)
	Total cash paid	$	56,267,000
	In addition, on November 30, 2012, due to a change of control, Kennedy Wilson began to consolidate KW Property Fund II, LP, (Fund II) a limited partnership that had been previously accounted for using the equity method and to whom Kennedy Wilson had advanced $39.6 million in notes receivable as of November 30, 2012 (see Note 3). This entity directly owns two office buildings which are encumbered by mortgage loans and has investments in real estate joint ventures which in aggregate own seven office properties. As a result of obtaining control of this entity, Kennedy Wilson applied Business Combinations guidance which requires assets and liabilities to be consolidated at fair value. Accordingly, $0.6 million in cash and cash equivalents, $2.7 million in other assets, $11.1 million in real estate, net, $75.4 million in investment in joint ventures, $1.6 million in accrued expenses and other liabilities, $5.827 million in notes payable, $8.9 million in mortgage loans payable and $7.6 million in noncontrolling interests were recorded as a result of the consolidation.
	As the fair value was in excess of the carrying value of Kennedy Wilson's equity method ownership interest, Kennedy Wilson recorded an acquisition related gain in the amount of $22.8 million in the accompanying consolidated statements of operations for the year ended December 31, 2012. See Note 7 - Fair Value Measurements for further of the methodology used to determine the fair value of the assets and liabilities acquired in this transaction.
	The results of operations of the properties acquired have been included in our consolidated financial statements since the date of their acquisition. The unaudited pro forma data presented below assumes that the acquisitions occurred as January 1, 2011. There was $2.1 million of revenues, $0.2 million of equity in joint venture income and $0.9 million of net loss attributable to common shareholders related to the acquisitions for the year ended December 31, 2012 reported in Kennedy Wilson’s consolidated statements of operations. The Company’s unaudited pro forma results have been prepared for comparative purposes only and do not purport to be indicative of the results of operations that would have occurred had these acquisitions been consummated at the beginning of the periods presented.

	2011 Consolidated Acquisitions
	During 2011, Kennedy Wilson acquired a 100% interest in an approximate 200,000 square foot office portfolio in Oakland, California (the "Portfolio") from a related party fund (the "Seller") in which Kennedy Wilson has a 5% ownership interest and the fund was accounted for under the equity method. The assets and liabilities of the Portfolio since the date of acquisition have been consolidated at fair value in accordance with Business Combinations guidance. The amounts of $15.0 million in building, $2.5 million in acquired intangibles, $6.2 million in land, $0.6 million in cash and cash equivalents, $0.1 million in accounts receivables and other assets, $16.0 million in mortgage loans payable, and $1.1 million in other liabilities were recorded as a result of the combination. Direct costs of the business combination have been charged to operations in the period that such costs were incurred. Additionally, Kennedy Wilson will pay the Seller 15% of all profits realized by Kennedy-Wilson in excess of a 10% internal rate of return upon disposition of the investment. Accordingly, Kennedy Wilson had recorded a liability of $0.2 million and $0.7 million, at fair value, for the 15% contingent interest as of December 31, 2012 and 2011, respectively. This interest will be re-evaluated on an on-going basis.
	As the fair value was in excess of price paid, Kennedy Wilson recorded a acquisition related gain in the amount of $6.3 million in the accompanying consolidated statements of operations for the year ended December 31, 2011. Fair value was determined using the income approach.
	2010 Acquisitions
	During 2010, Kennedy Wilson acquired its partners interest to obtain 100% of the interest in Fairways 340, LLC ("Fairways") that was previously accounted for under the equity method. The assets, liabilities, and results of the operations of Fairways at the date of acquisition were consolidated at fair value and direct costs of the business combination have been charged to operations in the period that such costs were incurred in accordance with Business Combinations guidance. Kennedy Wilson had a 49.83% ownership interest and equity with a fair value of $8.9 million before the combination and the combination was considered to be achieved in stages. As a result of remeasuring its basis at fair value (utilizing an income approach) upon the combination, Kennedy Wilson recorded an acquisition related gain in the amount of $2.1 million in the accompanying consolidated statements of operations for the year ended December 31, 2010.

	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, 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. The Company also accounts for four investments which are more than 50% owned under the equity method and they are further discussed below.
	As of December 31, 2012 and 2011, Kennedy Wilson's equity investment in joint ventures totaled $543.2 million and $343.4 million, respectively. The largest equity investment, KW Residential, LLC ("KWR"), had a balance of $102.7 million and $112.1 million as of December 31, 2012 and 2011, respectively. Kennedy Wilson owns approximately 41% of KWR. 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. During the year ended December 31, 2012 and 2011, Kennedy Wilson received cash distributions of $11.4 million and $9.3 million, respectively, from this joint venture investment. Additionally, during the year ended December 31, 2012 and 2011, Kennedy Wilson recognized $9.6 million in losses and $6.2 million in gains, respectively from foreign currency translation adjustments from its investment in KWR. The foreign currency losses and gains are included in other comprehensive income in the accompanying consolidated statements of equity and consolidated statements of comprehensive income. As of December 31, 2012, the Company did not have any other investments which individually exceeded 10% of the investment in joint venture balance.
	During the year ended December 31, 2012 and 2011, Kennedy Wilson made $178.7 million and $105.4 million, respectively, in contributions to new and existing joint venture investment of which $149.5 million and $63.6 million, respectively, were contributed to new joint ventures, respectively, and were invested in the following types of properties:
				Year Ended December 31, 2012					Year Ended December 31, 2011
						Kennedy Wilson					Kennedy Wilson
	Investment Type	Region		Number of Properties		Initial Contribution			Number of Properties		Initial Contribution

	Residential	Western U.S.		2		19,625,000			2		17,942,000

	Total			20		$	149,547,000		15		$	63,633,000
	During the year ended December 31, 2012 and 2011, Kennedy Wilson contributed $29.2 million and $41.8 million, respectively, to existing joint ventures to pay off existing debt, fund working capital and to acquire the interests of other members in joint ventures.
	During the year ended December 31, 2012 and 2011, Kennedy Wilson received $79.1 million and $36.3 million, respectively, in distributions from its joint ventures. During 2012, $34.1 million of the distributions resulted from the sale of five multifamily properties located in the Western United States and the sale of the Company's interest in a joint venture which held a multifamily property located in the Western Unites States. Kennedy Wilson's share of the gain recognized from these sales was $13.1 million, which is included in equity in joint venture income in the consolidated statements of operations. The remaining $45.0 million of distributions resulted from positive operating performance at the properties and return of investments in connection with the refinancing of debt at the properties.
	On November 30, 2012, due to a change of control, Kennedy Wilson began to consolidate Fund II, a limited partnership that had been previously accounted for using the equity method. See Note 4 for further discussion.
	During the year ended December 31, 2012, the Company acquired 49.5% of the non-managing membership interests in Bay Area Smart Growth Fund II, LLC. Prior to the acquisition, Kennedy Wilson had a 5% managing member interest and served as the non-controlling managing member. The terms of the partnership agreement require a vote of the majority interest of the non-managing members, whose commitments are greater than 50% of the aggregate capital commitments, in order to direct and control key decision making over the partnership. Since Kennedy Wilson acquired only 49.5% of the non-managing member interests, the Company has concluded that it does not control Bay Area Smart Growth Fund II, LLC and will continue to account for its interest in the entity as an equity method investment. As of December 31, 2012 and 2011, Kennedy Wilson's investment in this joint venture was $12.9 million and $1.0 million, respectively.
	In addition, during the year ended December 31, 2012, the Company, as a member, acquired a greater than 50% interest in three joint ventures, which own retail properties. Due to certain voting rights, control does not rest with the managing member nor with the other members and, as such, neither party has control. Since the Company concluded that it does not control these entities despite its greater than 50% ownership interest, it will account for its interest as equity method investments. At December 31, 2012, Kennedy Wilson's investment in these joint ventures were $7.8 million.
	Kennedy Wilson has determined that it has investments in five variable interest entities as of December 31, 2012 and has concluded that Kennedy Wilson is not the primary beneficiary of any of the investments. As of December 31, 2012, the variable interest entities had assets totaling $326.9 million with Kennedy Wilson’s exposure to loss as a result of its interests in these variable interest entities totaling $109.9 million related to its equity contributions.
	As of December 31, 2012, Kennedy Wilson has unfulfilled capital commitments totaling $8.3 million to four of its joint ventures. The Company may be called upon to contribute additional capital to joint ventures in satisfaction of Kennedy Wilson capital commitment obligations.
	Kennedy Wilson has certain guarantees associated with loans secured by assets held in various joint venture partnerships. The maximum potential amount of future payments (undiscounted) Kennedy Wilson could be required to make under the guarantees was approximately $55.5 million as of December 31, 2012. 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 Estimated Fair Value of Guarantees ASC Subtopic 460-10, the estimated fair value of guarantees made as of December 31, 2012 and December 31, 2011 is immaterial.
	Investments in which Kennedy-Wilson does not have significant influence are accounted for under the cost method of accounting. As of December 31, 2012 and 2011, Kennedy Wilson had three investments accounted for under the cost method with a carrying value totaling $5.7 million and $4.5 million, respectively.

	INVESTMENTS IN LOAN POOL PARTICIPATIONS
	As of December 31, 2012 and 2011, the Company's investment in loan pool participations totaled $95.6 million and $90.0 million, respectively.
	The Company's largest loan pool, which is secured by real estate primarily located in the United Kingdom (the “UK Loan Pool”), had a balance of $60.4 million and $60.0 million as of December 31, 2012 and 2011, respectively. In 2011, Kennedy Wilson, along with institutional partners, acquired this loan portfolio consisting of 58 performing loans. The 58 loans were secured by more than 170 properties comprised of the following product types: office, multifamily, retail, industrial, hotel and land. Kennedy Wilson, through a 50/50 joint venture with one of its partners, acquired a 25% participation interest in the pool for $440.9 million, of which $323.4 million was funded with debt that matures in October 2014. As of December 31, 2012, the unpaid principal balance of the loans were $765.8 million due to collections of $1.4 billion through December 31, 2012, representing 65% of the pool. As a result of the positive performance of the loan pool, the venture level debt had been paid down to $25.8 million as of December 31, 2012. Kennedy Wilson expects to accrete $23.0 million in interest income on the UK Loan Pool over the total estimated collection period (excluding asset management fees).
	The following table represents the demographics of the Company's investment in the loan pools including the initial unpaid principal balance ("UPB") and the UPB as of December 31, 2012.

FAIR VALUE MEASUREMENTS AND THE FAIR VALUE OPTION	12 Months Ended

Fair Value Disclosures [Abstract]	'
FAIR VALUE MEASUREMENTS AND THE FAIR VALUE OPTION	'
	FAIR VALUE MEASUREMENTS AND THE FAIR VALUE OPTION
	FAIR VALUE MEASUREMENTS—Fair Value Measurements and Disclosures ASC Subtopic 820-10 establishes a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to measurements involving significant unobservable inputs (Level 3 measurements). The three levels of the fair value hierarchy are as follows:
	Level 1—Valuations based on unadjusted quoted market prices in active markets for identical securities.
	Level 2—Valuations based on observable inputs (other than Level 1 prices), such as quoted prices for similar assets and quoted prices in markets that are not active.
	Level 3—Valuations based on inputs that are unobservable and significant to the overall fair value measurement, and involve management judgment.
	The level in the fair value hierarchy within which a fair value measurement in its entirety falls is based on the lowest level input that is significant to the fair value measurement in its entirety.
	The following table presents fair value measurements (including items that are required to be measured at fair value and items for which the fair value option has been elected) as of December 31, 2012:
		Level 1			Level 2			Level 3			Total
	Short term investments	$	—		$	10,000,000		$	—		$	10,000,000

	Kennedy-Wilson's investment in the ordinary stock units of the Bank of Ireland were classified as available-for-sale and were stated at fair value based upon observed market prices (Level 1 in the fair value hierarchy). Unrealized changes in value on these securities were included in accumulated other comprehensive income. As of December 31, 2012, the marketable securities were sold.
	The carrying value of short term investments approximates fair value due to the short maturities of these investments.
	The following table presents changes in Level 3 investments, investments in investment companies and investments in joint ventures that elected the fair value option, for the years ended December 31:
		2012			2011			2010
	Beginning balance	$	51,382,000		$	34,654,000		$	19,590,000

	Ending Balance	$	68,363,000		$	51,382,000		$	34,654,000
	The change in unrealized and realized gains and losses are included in equity in joint venture (loss) income in the accompanying consolidated statements of operations.
	The change in unrealized gains on level 3 investments during 2012 and 2011 for investments still held as of December 31, 2012 and 2011 were $8.6 million and $4.2 million, respectively.
	Kennedy Wilson records its investment 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. The Funds report their investments in real estate at fair value based on valuations of the underlying real estate holdings and indebtedness secured by the real estate. The valuations of real estate were based on management estimates of the real estate assets using income and market approaches. The indebtedness securing the real estate and the investments in debt securities were valued, in part, based on third party valuations and management estimates also using an income approach. The primary inputs for these valuations are unobservable and include discount rates, capitalization rates and projected growth rates. Increases in fair value for the Funds of $1.7 million, $0.9 million, and $3.7 million were recorded in equity in joint venture income in the accompanying consolidated statements of operations for the years ended December 31, 2012, 2011 and 2010, respectively. Kennedy Wilson’s investment balance in the Funds was $25.8 million and $23.4 million at December 31, 2012 and 2011, respectively, which are included in investments in joint ventures in the accompanying consolidated balance sheet. As of December 31, 2012 and 2011, Kennedy Wilson has unfunded capital commitments to the Funds in the amounts of $3.4 million and $5.3 million, respectively.
	FAIR VALUE OPTION—Kennedy Wilson elected the fair value option for two investments in joint venture entities that were acquired during 2008. Kennedy Wilson elected to record these investments at fair value to more accurately reflect the timing of the value created in the underlying investments and report those results in current operations. In May 2011, Kennedy Wilson purchased an additional 24% (increasing its interest from 24% to 48%) interest in one of its fair value option investments for $7.0 million from a related party fund. Since the purchase price was less than the fair value of this interest at the time of purchase, this transaction resulted in Kennedy Wilson recording an increase in fair value of $4.8 million in equity in joint venture income in the accompanying consolidated statements of operations for the year ended December 31, 2011. During the years ended December 31, 2012, 2011, and 2010, Kennedy Wilson recorded an increase in fair value of both fair value option investments of $7.9 million,$3.4 million, and $2.5 million, respectively, in equity in joint venture income in the accompanying consolidated statements of operations. Kennedy Wilson determines the fair value of these investments based upon the income approach, utilizing estimates of future cash flows, discount rates and liquidity risks. As of December 31, 2012 and 2011, these two investments had fair values of $42.6 million and $27.9 million, respectively.
	In estimating fair value of real estate held by the Funds, two joint ventures that elected the fair value option investments and the value of the assets and liabilities acquired in connection with the change in control and consolidation of Fund II (as further described in Note 4), Kennedy-Wilson considers significant inputs such as capitalization and discount rates. The table below describes the range of inputs used as of December 31, 2012 for real estate assets:
		Estimated rates used for
		Capitalization rates		Discount Rates
	Multifamily	5.75% — 7.00%		7.50% — 9.00%
	Office	6.25% — 7.50%		7.50% — 9.75%
	Retail	8.00%		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, cannot be substantiated by comparison to quoted prices in active markets, and 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.
	DERIVATIVE FINANCIAL INSTRUMENTS AND HEDGING ACTIVITIES—During the year ended December 31, 2012, Kennedy Wilson entered into a currency forward contract to manage its exposure to currency fluctuations between its functional currency (U.S. dollars) and the functional currency (Euros) of certain of its wholly owned subsidiaries and joint venture investments and its exposure to currency fluctuations caused by its investment in marketable securities. To accomplish this objective, Kennedy Wilson hedged these exposures by entering into a currency forward contract to sell €16,000,000 at a forward rate. This hedging instrument is expected to partially hedge Kennedy Wilson's exposure to its net investment in certain foreign operations and the changes in fair value of the marketable securities caused by currency fluctuations. The currency forward contract matures on June 4, 2015. The currency forward contract is 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 December 31, 2012, 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. The fair value of the derivative instrument held as of December 31, 2012 was $1.5 million and is included in accrued expenses and other liabilities on the consolidated balance sheet.
	For the year ended December 31, 2012, the Company recorded a loss of $1.2 million in other comprehensive income in the accompanying consolidated statements of comprehensive income 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. During the year ended December 31, 2012, a portion of the currency forward contract was used to hedge currency exposure of Kennedy Wilson's investment in marketable securities which qualified as a fair value hedge under ASC Topic 815 and, accordingly, for the year ended December 31, 2012, Kennedy Wilson recorded a loss of $0.3 million in general and administrative expenses in the accompanying consolidated statements of operations.
	FAIR VALUE OF FINANCIAL INSTRUMENTS—The carrying amounts of cash and cash equivalents, accounts receivable including related party, accounts payable, accrued expenses and other liabilities, accrued salaries and benefits, deferred and accrued income taxes, and income tax receivable 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. As of December 31, 2012 and December 31, 2011, senior notes payable, borrowings under lines of credit, mortgage loans payable and junior subordinated debentures was estimated to be approximately $708.2 million and $312.8 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 $686.2 million and $320.1 million at December 31, 2012 and December 31, 2011, respectively.

These subsidiaries held ownership interests in unconsolidated co-investment vehicles (each a "Fund Entity"). In the transactions, interests held in the subsidiaries were exchanged for interests in the Fund Entities. As a result of the transactions, each of the subsidiaries became a wholly-owned subsidiary of Kennedy-Wilson, Inc., and each of the Executives, the Executive Entities and unaffiliated third parties continues to hold an economic interest in the relevant Fund Entity that is economically equivalent to the interest held by it prior to such transactions.

	Based upon the level of historical taxable income and projections for future taxable income over the periods which Kennedy-Wilson’s gross deferred tax assets are deductible, management believes it is more likely than not Kennedy-Wilson will realize the benefits of these deductible differences at December 31, 2012.
	As of December 31, 2012 Kennedy Wilson had federal net operating losses of $71.1 million. These net operating losses begin to expire in the year 2030. As of December 31, 2012 there were also California net operating loss carryforwards of approximately $32.8 million. The California net operating losses begin to expire after the year 2028. In addition, Kennedy Wilson has $7.2 million of other state net operating losses. We believe that it is more likely than not that certain state net operating losses will expire before the Kennedy Wilson can realize the benefit of the losses. We have provided a valuation allowance of $0.4 million as of December 31, 2012 for certain state net operating losses.
	Presently a deferred tax liability for undistributed earnings of subsidiaries located outside the United States has not been recorded. These earnings may become taxable upon a payment of a dividend or as a result of a sale or liquidation of the subsidiaries. At this time we don't have plans to repatriate income from our foreign subsidiaries, however to the extent that are able to repatriate such earnings in a tax free manner, or in the event of a change in our capital situation or investment strategy, it is possible that the foreign subsidiaries may pay a dividend which would impact our effective tax rate. Unremitted earnings of foreign subsidiaries, which have been, or are intended to be permanently invested, aggregated approximately $34.2 million as of December 31, 2012. If these subsidiaries' earnings were repatriated to the United States additional US domestic taxes of $7.4 million would be incurred.
	There were no gross unrecognized tax benefits at December 31, 2012 and December 31, 2011. Management has considered the likelihood and significance of possible penalties associated with Kennedy-Wilson's current and intended filing positions and has determined, based on its assessment, that such penalties, if any, would not expected to be significant.
	Kennedy-Wilson's federal income tax returns remain open to examination for the years 2008 through 2012. Kennedy-Wilson is currently under examination for 2008, 2009 and 2010.
	For income tax purposes, distributions paid to common stockholders and preferred shareholder are return of capital for the year ended December 31, 2012.

As of December 31, 2012 all the restricted share awards were granted to employees, which vest ratably over a five year period. Vesting of the restricted share awards is contingent upon the expected achievement of a performance target as of the initial vesting date of November 13, 2010 and each of the next four years thereafter. The performance targets were achieved for 2010, 2011 and 2012. From inception of the plan through December 31, 2012, 1,454,467 shares have vested and been issued to participants and 23,512 shares have been forfeited.

The shares vest over five years with 40% vesting ratably in the first four years of the award period and the remaining 60% in the fifth year of the award period. Vesting of the restricted share awards is contingent upon the expected achievement of a performance target in each year of the award period with the initial vesting of the first 10% in January 2013. The performance targets were achieved for 2012. As of December 31, 2012, there was $38.0 million of unrecognized compensation cost for the Equity Plan related to unvested restricted shares which will vest over the next four years.

	The certificate of designations of the Preferred Stock contain provisions that require Kennedy Wilson to commence an offer to purchase all shares of the Preferred Stock at a purchase price in cash per share of Preferred Stock equal to $1,150 plus all accumulated and accrued dividends upon the occurrence of a fundamental change, defined as a change of control. The parties have agreed that a change of control is deemed to occur when any person or group other than the purchaser of the Preferred Stock and its affiliates, or any officer or director of Kennedy Wilson as of the issue date of the Preferred Stock, acquires directly or indirectly voting control or direction over more than 35% of the voting control of Kennedy Wilson for a period of seven consecutive days following the earlier of the date the company becomes aware of such acquisition and the date such person or group files a Schedule 13D. This change of control provision is within Kennedy-Wilson’s control as the Board of Directors, at its discretion, would be able to issue blank check Preferred Stock at any time for any reason which could dilute the person or group to below the 35% of the voting control threshold. As such, Kennedy Wilson has concluded that the change of control is within the control of Kennedy-Wilson and therefore has classified the Preferred Stock as permanent equity in the accompanying consolidated balance sheets.
	In connection with the issuance of the Preferred Stock, Kennedy Wilson entered into registration rights agreements that allow for the holders of the Preferred Stock, with at least a 51% vote, to demand registration of the Preferred Stock (or converted common stock) on or after November 13, 2010. If Kennedy Wilson does not satisfy the demand for registration, the holders of the Preferred Stock (or converted common stock) would be entitled to receive a payment in an amount equal to 1.50% per annum of the liquidation preference of $1,000 per share. There are sufficient shares of unregistered common stock authorized and unissued to accommodate the conversion feature.
	Warrants
	In April 2010, the Board of Directors authorized a warrant repurchase program enabling Kennedy Wilson to repurchase up to 12.5 million of its outstanding warrants. The warrants carry an exercise price of $12.50 with an expiration date of November 14, 2014. Kennedy Wilson may call for redemption of the warrants in whole and not in part at a price of $0.01 per warrant if the share price of its common stock equals or exceeds $19.50 per share for any 20 trading days within a 30 trading day period ending on the third business day prior to the notice of redemption to warrant holders, or upon not less than 30 days’ prior written notice of redemption to each warrant holder. During the years ended December 31, 2012 and 2011, Kennedy Wilson repurchased a total of 0.6 million and 3.4 million, respectively of its outstanding warrants for total consideration of $1.6 million and $6.1 million. There are 5.8 million warrants outstanding as of December 31, 2012.

	SUBSEQUENT EVENTS
	Subsequent to December 31, 2012, KW Residential, LLC settled several Japanese yen related hedges resulting in cash proceeds of $23.7 million to the joint venture, of which our share was $10.6 million.
	In December 2012, at time of acquisition, Kennedy Wilson invested $43.6 million of its equity and borrowed $79.3 million to acquire a loan secured by a shopping center in the United Kingdom. Additionally, in partnership with an institutional investor, we acquired a loan pool with an unpaid principal balance of $232.3 million, comprised of 7 loans secured by 23 underlying properties in the United Kingdom.  Kennedy Wilson's investment in the pool totaled $16.0 million. Subsequent to December 31, 2012, we sold 50% of our interest in both investments to an institutional investor.
	In March 2013, Kennedy Wilson drew $35 million on its unsecured credit facility, bringing the outstanding balance to $35 million and availability to $65 million.
	In March 2013, Kennedy Wilson issued 9.0 million shares of common stock primarily to institutional investors, resulting in gross proceeds of $141.3 million of which $35.0 million was used to pay off the outstanding balance on our line of credit. In April 2013, the Company issued 1.4 million shares of common stock as a result of the underwriters fully exercising their overallotment option, which resulted in gross proceeds of $21.2 million.
	In September 2013, Kennedy Wilson completed an offering of 6.9 million shares (which includes 900,000 shares from the underwriters fully exercising their option to purchase additional shares) of its common stock, which raised $122.2 million of net proceeds.
	In September 2013, the Company amended its existing unsecured revolving credit facility which increased the total principal amount available to be borrowed by an additional $40.0 million, for an aggregate of $140.0 million. The maturity date was extended to October 1, 2016. The credit facility was undrawn as of September 30, 2013.

BASIS_OF_PRESENTATION_AND_SUMM1

BASIS OF PRESENTATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)	12 Months Ended
	Dec. 31, 2012
Accounting Policies [Abstract]	'
BASIS OF PRESENTATION	'
	BASIS OF PRESENTATION—The consolidated financial statements include the accounts of Kennedy Wilson and its wholly owned 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 (VIE) as defined by FASB Accounting Standards Codification (ASC) Subtopic 810 – Consolidation and to assess whether it is the primary beneficiary of such entities. In determining whether Kennedy Wilson is the primary beneficiary of a VIE, qualitative and quantitative factors are considered, including, but not limited to: the amount and characteristics of Kennedy-Wilson's investment; the obligation or likelihood for Kennedy Wilson to provide financial support; Kennedy Wilson's ability to control or significantly influence key decisions for the VIE; and the similarity with and significance to the business activities of Kennedy Wilson. Significant judgments related to these determinations include estimates about the future fair values and performance of real estate held by these VIEs and general market conditions. As of December 31, 2012, Kennedy-Wilson has determined that it does not have any VIEs except as discussed in the joint ventures policy below.
USE OF ESTIMATES	'
	USE OF ESTIMATES—The preparation of the accompanying consolidated financial statements in conformity with U.S. generally accepted accounting principles (GAAP) 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. Management evaluates its estimates and assumptions on an ongoing basis using historical experience and other factors, including the current economic environment, which management believes to be reasonable under the circumstances. Management adjusts such estimates and assumptions when facts and circumstances dictate. The after-effects of the recent global financial crisis, including highly volatile credit, equity and foreign currency markets and a slow and uneven global economic recovery, have increased the uncertainty inherent in such estimates and assumptions. As future events and their effects cannot be determined with precision, actual results could differ significantly from these estimates. Changes in those estimates will be reflected in the financial statements in future periods.
REVENUE RECOGNITION	'
	REVENUE RECOGNITION—Revenue primarily consists of management fees, performance fees, commission revenue, rental income and sales of real estate.
	Management fees are primarily comprised of property management fees and base asset management fees. Property management fees are earned for managing the operations of real estate assets and are generally based on a fixed percentage of the revenues generated from the respective real estate assets. Base asset management fees are earned from limited partners of funds Kennedy-Wilson sponsors and are generally based on a fixed percentage of committed capital or net asset value. These fees are recognized as revenue ratably over the period that the respective services are performed.
	Performance fees or carried interest 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 fund 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 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 performances fees recognized to date through December 31, 2012 that may be reversed in future periods if there is negative fund performance totaled $12.8 million. Performance fees accrued as of December 31, 2012 and 2011 were $8.6 million and $4.2 million, respectively, and are included in accounts receivable—related parties in the accompanying consolidated balance sheet.
	Commissions primarily consist of acquisition fees, auction and real estate sales commissions and leasing commissions. Acquisition fees are earned for identifying and closing investments on behalf of investors and are based on a fixed percentage of the acquisition price. Acquisition fees are recognized upon the successful completion of an acquisition after all required services have been performed. In the case of auction and real estate sales commissions, the revenue is generally recognized when escrow closes. In accordance with the guidelines established for Reporting Revenue Gross as a Principal versus Net as an Agent in the ASC Subtopic 605-45, Kennedy Wilson records commission revenues and expenses on a gross basis. Of the criteria listed in the Subtopic 605-45, Kennedy Wilson is the primary obligor in the transaction, does not have inventory risk, performs all or part of the service, has credit risk, and has wide latitude in establishing the price of services rendered and discretion in selection of agents and determination of service specifications. Leasing fees that are payable upon tenant occupancy, payment of rent or other events beyond Kennedy Wilson's control are recognized upon the occurrence of such events.
	Rental income from operating leases is generally recognized on a straight-line basis over the terms of the leases.
	Sales of real estate are recognized at the close of escrow when title to the real property passes to the buyer and there is no continuing involvement in the real property. Kennedy Wilson follows the requirements for profit recognition as set forth by the Sale of Real Estate ASC Subtopic 360-20.
REAL ESTATE ACQUISITIONS	'
	REAL ESTATE ACQUISITIONS—When acquiring a property, the purchase price of acquired properties is recorded to land, buildings and building improvements and intangible lease value (value of above-market and below-market leases, acquired in-place lease values, and tenant relationships, if any) based on their respective estimated fair values in accordance with Business Combinations ASC Subtopics 805-10. Acquisition-related costs are expensed as incurred.
	The valuations of real estate are based on management estimates of the real estate assets using income and market approaches. The indebtedness securing the real estate are valued, in part, based on third party valuations and management estimates also using an income approach.
INVESTMENTS IN JOINT VENTURES	'
	INVESTMENTS IN JOINT VENTURES—Kennedy Wilson has a number of joint venture interests, that were formed to acquire, manage, and/or sell real estate and invest in loan pools and discounted loan portfolios. Investments in joint ventures which Kennedy Wilson does not control are accounted for under the equity method of accounting as Kennedy Wilson can exercise significant influence, but does not have the ability to control the joint venture. An investment in a joint venture is recorded at its initial investment and is increased or decreased by Kennedy Wilson’s share of income or loss, plus additional contributions and less distributions. A decline in the value of an investments in a joint venture that is other than temporary is recognized when evidence indicates that such a decline has occurred in accordance with Equity Method Investments ASC Subtopic 323-10. As of December 31, 2012, Kennedy Wilson also had investments in five joint venture investments which are VIEs in which Kennedy Wilson is not the primary beneficiary and therefore accounts for them under the equity method as well.
	Profits on the sale of real estate held by joint ventures in which Kennedy Wilson has continuing involvement are deferred until such time that the continuing involvement has been concluded and all the risks and rewards of ownership have passed to the buyer. Profit on sales to joint ventures in which Kennedy Wilson retains an equity ownership interest results in partial sales treatment in accordance with Sale of Real Estate ASC Subtopic 360-20, thus deferring a portion of the gain as a result of Kennedy Wilson’s continuing ownership percentage in the joint ventures.
	Kennedy Wilson has three investments in joint ventures, KW Property Fund III, L.P. (KW Fund III), Kennedy Wilson Real Estate Fund IV, L.P. (Fund IV) and SG KW Venture I, LLC (the Funds) that are investment companies under the Investment Companies ASC Subtopic 946-10. Thus, the Funds reflect their investments at fair value, with unrealized gains and losses resulting from changes in fair value reflected in their earnings. Kennedy Wilson has retained the specialized accounting for the Funds pursuant to Retention of Specialized Accounting for Investments in Consolidation ASC Subtopic 810-10 in recording its equity in joint venture income from the Funds.
	Additionally, Kennedy Wilson elected the fair value option for two investments in joint venture entities that were acquired during 2008. Kennedy-Wilson elected to record these investments at fair value to more accurately reflect the timing of the value created in the underlying investments and report those results in current operations.
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 note receivable 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 which, 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. Interest income from investments in notes receivable which the Company originates are recognized at the stated interest rate.
FAIR VALUE MEASUREMENTS	'
	FAIR VALUE MEASUREMENTS—Kennedy Wilson accounts for fair value measurements of financial assets and financial liabilities and for fair value measurements of nonfinancial items that are recognized or disclosed at fair value in the financial statements on a recurring basis under the provisions of Fair Value Measurements ASC Subtopic 820-10. Subtopic 820-10 defines fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. When estimating fair value in the absence of an orderly transaction between market participants, valuations of real estate are based on management estimates of the real estate assets using income and market approaches. The indebtedness securing the real estate and the investments in debt securities are valued, in part, based on third party valuations and management estimates also using an income approach.
GOODWILL	'
	GOODWILL—Goodwill results from the difference between the purchase price and the fair value of net assets acquired based upon the purchase method of accounting for business combinations. In accordance with Accounting for Goodwill ASC Subtopic 350-20, goodwill is reviewed for impairment on an annual basis. In testing for impairment, goodwill is assigned to the reporting unit based upon the amount of goodwill generated at the time of acquisition of the businesses by the reporting unit. The Company first perform a qualitative assessment annually at each reporting unit that has goodwill to determine if facts and circumstances indicate that goodwill is more likely than not impaired. If the qualitative assessment indicates that goodwill of a reporting unit is not more likely than not impaired, we do not perform a quantitative impairment test for the reporting unit. If the qualitative assessment indicates that goodwill of a reporting unit is more likely than not impaired, we perform the first step, or step 1, of the quantitative goodwill impairment test. The Company performs its annual review of impairment at year end and when a triggering event occurs between annual year end reviews.
CASH AND CASH EQUIVALENTS	'
	CASH AND CASH EQUIVALENTS—Cash and cash equivalents consist of cash and all highly liquid investments purchased with maturities of three months or less. Cash and cash equivalents are invested in institutions insured by government agencies. Certain accounts contain balances in excess of the insured limits. Kennedy Wilson's operations and financial position are affected by fluctuations in currency exchange rates between the Yen and European currencies against the U.S. Dollar.
SHORT TERM INVESTMENTS	'
	SHORT TERM INVESTMENTS—Short term investments, which have an original maturity of one year or less, are carried at amortized cost, which approximates fair value.
LONG-LIVED ASSETS	'
	LONG-LIVED ASSETS—Kennedy-Wilson reviews its long-lived assets (excluding goodwill) whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable in accordance with Impairment of Long-Lived Assets ASC Subtopic 360-10. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to estimated undiscounted future cash flows expected to be generated by the asset. If the carrying amount of an asset exceeds its estimated undiscounted future cash flows, an impairment charge is recognized in the amount by which the carrying amount of the asset exceeds the fair value of the asset. Assets to be disposed of are presented separately in the balance sheet and reported at the lower of the carrying amount or fair value less costs to sell, and are no longer depreciated. The assets and liabilities of the assets to be disposed of are classified as held for sale and would be presented separately in the appropriate asset and liability sections of the balance sheet.
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 and is determined based on historical experience. The Company reviews its accounts receivable for probable credit losses on a quarterly basis. As of December 31, 2012, the Company had an immaterial allowance for doubtful accounts and during the years ended December 31, 2012, 2011 and 2010 had recorded no provision for doubtful accounts.
FAIR VALUE OF FINANCIAL INSTRUMENTS	'
	FAIR VALUE OF FINANCIAL INSTRUMENTS—The estimated fair value of financial instruments is determined using available market information and appropriate valuation methodologies. Considerable judgment, however, is necessary to interpret market data and develop the related estimates of fair value. Accordingly, the estimates presented herein are not necessarily indicative of the amounts that could be realized upon disposition of the financial instruments. The use of different market assumptions or estimation methodologies may have a material impact on the estimated fair value amounts.
NONCONTROLLING INTERESTS	'
	NONCONTROLLING INTERESTS—Noncontrolling interests are reported within equity as a separate component of Kennedy-Wilson's equity in accordance with Noncontrolling Interests in Consolidated Financial Statements ASC Subtopic 810-10. Revenues, expenses, gains, losses, net income or loss, and other comprehensive income are reported in the consolidated statements of operations at the consolidated amounts and net income and comprehensive income attributable to noncontrolling interests are separately stated.
CAPITALIZED INTEREST	'
	CAPITALIZED INTEREST—Kennedy-Wilson capitalizes interest in accordance with Capitalization of Interest Cost ASC Subtopic 835-20 for assets that are undergoing development or entitlement activities in preparation for their planned principal operations. For qualifying equity investments, interest is capitalized in accordance with Capitalization of Interest Cost in Financial Statements That Include Investments Accounted for Under the Equity Method ASC Subtopic 835-20. An appropriate interest rate is applied to Kennedy-Wilson’s cash investment in the qualifying asset. Interest capitalization begins upon the commencement of development activities and ceases when the investment has begun its planned principal operations.
DERIVATIVE FINANCIAL INSTRUMENTS AND HEDING ACTIVITIES	'
	DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES—Kennedy Wilson has joint ventures that hold derivatives to reduce their exposure to foreign currencies. 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.
GUARANTEES	'
	GUARANTEES—Kennedy-Wilson has certain guarantees associated with loans secured by assets held in various joint venture investments. The maximum potential amount of future payments (undiscounted) Kennedy Wilson could be required to make under the guarantees was $55.5 million and $26.7 million at December 31, 2012 and 2011, respectively. The guarantees expire through 2017 and Kennedy Wilson’s performance under the guarantees would be required to the extent there is a shortfall in liquidation between the principal amount of the loan and the net sales proceeds of the asset. Based upon Kennedy Wilson’s evaluation of guarantees under Estimated Fair Value of Guarantees ASC Subtopic 460-10, the estimated fair value of guarantees made as of December 31, 2012 and 2011 is immaterial.
CONCENTRATION OF CREDIT RISK	'
	CONCENTRATION OF CREDIT RISK—Financial instruments that subject Kennedy Wilson to credit risk consist primarily of accounts and notes receivable and cash equivalents. Credit risk is generally diversified due to the large number of entities composing Kennedy Wilson’s customer base and their geographic dispersion throughout the United States, the United Kingdom, Ireland and Japan. Kennedy Wilson performs ongoing credit evaluations of its customers and debtors.
EARNINGS PER SHARE	'
	EARNINGS PER SHARE—Basic earnings per share is computed based upon the weighted average number of shares of common stock outstanding during the periods presented. Diluted earnings per share is computed based upon the weighted average number of shares of common stock and potentially dilutive securities outstanding during the periods presented. The dilutive impact of potentially dilutive securities including warrants, convertible securities, and unvested stock which were outstanding during the period is calculated by the “treasury stock” method.
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 statements of equity and comprehensive income as a component of accumulated other comprehensive income.
COMPREHENSIVE (LOSS) INCOME	'
	COMPREHENSIVE (LOSS) INCOME—Comprehensive (loss) income consists of net income (loss) and other comprehensive income (loss). In the accompanying consolidated balance sheets, accumulated other comprehensive income consists of foreign currency translation adjustments and unrealized gains (losses) on available for sale securities and derivative instruments.
REPURCHASE OF EQUITY INSTRUMENTS	'
	REPURCHASE OF EQUITY INSTRUMENTS—Upon the decision to retire repurchased equity instruments, Kennedy Wilson records the retirement as a reduction to additional paid in capital.
SHARE-BASED PAYMENT ARRANGEMENTS	'
	SHARE-BASED PAYMENT ARRANGEMENTS—Kennedy Wilson accounts for its share-based payment arrangements under the provisions of Share-Based Payments ASC Subtopic 718-10. Compensation cost for employee service received in exchange for an award of equity instruments is based on the grant-date fair value of the share-based award that is ultimately settled in equity of Kennedy Wilson. The cost of employee services is recognized over the period during which an employee provides service in exchange for the share-based payment award. Share-based payment arrangements with only services conditions that vest ratably over the requisite service period are recognized on the straight-line basis and performance awards that vest ratably are recognized on a tranche by tranche basis over the performance period. Unrecognized compensation costs for share-based payment arrangements that have been modified are recognized over the original service or performance period.
FAIR VALUE OPTION	'
	FAIR VALUE OPTION—Kennedy-Wilson accounts for financial assets and financial liabilities at fair value on an instrument-by-instrument basis, with changes in fair value reported in earnings in accordance with the provisions of Fair Value Measurements and Disclosures ASC Subtopic 820-10.
INCOME TAXES	'
	INCOME TAXES—Income taxes are accounted for under the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and operating loss and tax credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. In accordance with Accounting for Uncertainty in Income Taxes ASC Subtopic 740-10, Kennedy-Wilson recognizes the effect of income tax positions only if those positions are more likely than not of being sustained. Recognized income tax positions are measured at the largest amount that is greater than 50% likely of being realized. Changes in recognition or measurement are reflected in the period in which the change in judgment occurs.
	Kennedy-Wilson records interest related to unrecognized tax benefits in interest expense and penalties in selling, general, and administrative expenses.
RECLASSIFICATIONS	'
	RECLASSIFICATIONS—Certain balances included in prior years' financial statements have been reclassified to conform with the current year's presentation.
