Organization, Consolidation and Presentation of Financial Statements [Abstract]
BASIS OF PRESENTATION	BASIS OF PRESENTATION Kennedy Wilson's 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 ("U.S. GAAP") may have been condensed or omitted pursuant to SEC rules and regulations, although the Company believes that the disclosures are adequate to make their presentation not misleading. In the Company's opinion, all adjustments, consisting of only normal and recurring items, necessary for a fair presentation of the results of operations for the three and six months ended June 30, 2018 and 2017 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, 2018 . For further information, your attention is directed to the footnote disclosures found in the Company's Annual Report on Form 10-K for the year ended December 31, 2017 . Throughout these unaudited interim consolidated financial statements “Kennedy Wilson,” is referenced which is defined as the Company and its subsidiaries that are consolidated in its financial statements under U.S. GAAP. All significant intercompany balances and transactions have been eliminated in consolidation. "KW," “KWH,” “Kennedy Wilson,” the “Company,” “we,” “our,” or “us” are also referred to which are defined as Kennedy-Wilson Holdings, Inc. and its wholly-owned subsidiaries. In addition, throughout these unaudited interim consolidated financial statements, “equity partners” is referred to which is defined as the non-wholly owned subsidiaries that are consolidated in the Company's financial statements under U.S. GAAP, including third-party equity providers. Kennedy Wilson evaluates its relationships with other entities to identify whether they are variable interest entities ("VIEs") as defined in the ASC Subtopic 810-10, as amended by Accounting Standards Update ("ASU") 2015-02, 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 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. See comment in Note 4 about the preliminary nature of the estimates used in relation to acquisitions.

Summary of Significant Accounti

Summary of Significant Accounting Polices and Adoption of New Accounting Pronouncements	6 Months Ended

Accounting Policies [Abstract]
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES AND ADOPTION OF NEW ACCOUNTING PRONOUNCEMENTS	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES AND ADOPTION OF NEW ACCOUNTING PRONOUNCEMENTS REVENUE RECOGNITION—In May 2014, the Financial Accounting Standards Board (“FASB”) issued ASC Topic 606, Revenue from Contracts with Customers, which introduced a new five step model to recognize revenue from customer contracts in an effort to increase consistency and comparability throughout global capital markets and across industries. The model identifies the contract, any separate performance obligations in the contract, determines the transaction price, allocates the transaction price and recognizes revenue when the performance obligations are satisfied. Management has concluded that, with the exception of carried interests and incentive fees, the nature of the Company's revenue streams is such that the requirements are generally satisfied at the time that the fee becomes receivable. Consequently, the new standard did not impact the timing of revenue recognition for these revenue streams . The Company has concluded that carried interests, which are a performance-based capital allocation to the Company based on cumulative fund performance to-date, represent equity method investments that are not in the scope of the amended revenue recognition guidance. Effective January 1, 2018, the Company changed its policy for recognition and measurement of performance fees. This accounting policy change did not change the timing or amount of income recognized related to performance fees. Prior to this accounting method change, the performance-based component of the fees was recognized within investment management, property services and research fees in the Consolidated Statements of Operations. Under the equity method of accounting, the Company now recognizes its allocation of performance fees along with its share of income or loss and fair value, proportionate to the Company’s equity ownership in each applicable investment as a component of income from unconsolidated investments. The Company has accounted for this change by full retrospective application and prior periods presented have been recast. The impact of adoption was a reclassification of $32.9 million from other assets to unconsolidated investments on the consolidated balance sheet as of December 31, 2017. During the three and six months ended June 30, 2018 , there was $6.9 million and $17.2 million of performance-based carried interest allocations recorded as a component of income from unconsolidated investments. During the three and six months ended June 30, 2017 , there was $(2.6) million and $3.9 million of performance fee allocations which were previously presented as a component of investment management, property services and research fees and have been reclassified to income from unconsolidated investments in the current year presentation. ASC Subtopic 610-20, Other Income - Gains and Losses from the Derecognition of Nonfinancial Assets ("Subtopic 610-20") was also adopted effective January 1, 2018. Management concluded that the new standard did not have a significant impact on the amount, timing or classification of real estate sales in the financial statements or related disclosures. This conclusion was based on the Company's current business mix and general approach to sales of real estate which are generally completed without seller financing or continuing involvement that would indicate that a performance obligation is not met at the time the transaction closes. With the adoption of Subtopic 610-20 the Company will recognize the entire gain attributed to contributions of real estate properties to unconsolidated entities. The Company previously recognized a gain on contribution only to the extent of the third-party ownership in the unconsolidated entity acquiring the property and deferred the portion of the gain related to the Company's ownership. The Company’s analysis included evaluation of an in-process development project that will be completed later in 2018 and found that while the evaluation is different under Subtopic 610-20, the recognition required recording the gain on the sale of the land and the development component, as separate performance obligations, under a percentage of completion methodology. However, this conclusion is identical to the manner of reporting the gain on the sale of this real estate under the superseded U.S. GAAP. Consequently, there was no significant impact upon this sale nor any of the other sales already completed. REAL ESTATE ACQUISITIONS—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). The ownership of the other interest holders in consolidated subsidiaries is reflected as noncontrolling interests. 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 is valued, in part, based on third party valuations and management estimates also using an income approach. FOREIGN CURRENCIES—The financial statements of Kennedy Wilson's subsidiaries located outside the United States are measured using the local currency as this is their 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 and the British pound sterling. 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. Investment level debt is generally incurred in local currencies. Fluctuations in foreign exchanges rates may have a significant impact on the results of our operations. In order to manage the effect of these fluctuations, the Company enters into hedging transactions, in the form of currency derivative contracts, that are designed to reduce its book equity exposure to foreign currencies. See Note 6 for a complete discussion on currency derivative contracts. FAIR VALUE MEASUREMENTS — Kennedy Wilson accounts for fair value measurements of financial assets and financial liabilities and for fair value measurements of non-financial 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. 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. 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. Fluctuations in foreign exchanges rates may have a significant impact on the Company's results of operations. In order to manage the potential exposure from adverse changes in foreign exchange rates arising from the Company’s net investments in foreign operations, the Company may enter into currency derivative contracts to hedge all or portions of the net investments in the Company’s non-U.S. dollar denominated foreign operations. 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 ASC Subtopic 740-10, Accounting for Uncertainty in Income Taxes , the effect of income tax positions is recognized only if those positions are more likely than not to be 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. RECENT ACCOUNTING PRONOUNCEMENTS—On January 1, 2018, Kennedy Wilson adopted ASC Topic 606 and ASC Subtopic 610-20 transition guidance. See discussion above in revenue recognition for more detail. In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842) , which sets out the principles for the recognition, measurement, presentation and disclosure of leases for both parties to a contract (i.e., lessees and lessors). The new standard requires lessees to apply a dual approach, classifying leases as either finance or operating leases based on the principle of whether or not the lease is effectively a financed purchase by the lessee. This classification will determine whether lease expense is recognized based on an effective interest method or on a straight-line basis over the term of the lease. A lessee is also required to record a right-of-use asset and a lease liability for all leases with a term of greater than 12 months regardless of their classification. Leases with a term of 12 months or less will be accounted for similar to existing guidance for operating leases today. The new standard requires lessors to account for leases using an approach that is substantially equivalent to existing guidance for sales-type leases, direct financing leases and operating leases. ASU 2016-02 is required to be adopted for fiscal years beginning after December 15, 2018. Because Kennedy Wilson's existing operating lease commitments are not material and the accounting for leases by the lessor is substantially unchanged, the Company does not expect the ASU to have a significant impact on its results of operations or financial position. In August 2016, the FASB issued ASU 2016-15, Classification of Certain Cash Receipts and Cash Payments , which addresses eight classification issues related to the statement of cash flows: (a) debt prepayment or debt extinguishment costs, (b) settlement of zero-coupon bonds, (c) contingent consideration payments made after a business combination (d) proceeds from the settlement of insurance claims, (e) proceeds from the settlement of corporate-owned life insurance policies, including bank-owned life insurance policies, (f) distributions received from equity method investees, (g) beneficial interests in securitization transactions, and (h) separately identifiable cash flows and application of the predominance principle. ASU 2016-15 is required to be adopted for public entities for fiscal years beginning after December 15, 2017. The adoption of this standard did not have a material impact on Kennedy Wilson's consolidated financial statements. In January 2017, the FASB issued ASU 2017-01, Business Combinations (Topic 805): Clarifying the Definition of a Business. The ASU clarifies the definition of a business. The three elements of a business (inputs, processes, and outputs) has not changed, however, the amendment provides a framework to assist entities in evaluating whether these elements are present. The amended framework is not expected to materially impact the Company’s financial statements. However, the amendment also includes a provision that when substantially all of the fair value of the gross assets acquired (or disposed of) is concentrated in a single identifiable asset or a group of similar identifiable assets, the set is not a business. Therefore, real estate acquisitions generally will no longer be considered a business and consequently not be accounted for under Topic 805. The Company has evaluated the impact noting that for asset acquisitions (1) acquisition related costs will no longer be expensed as incurred and (2) regardless of the market value of a property at the acquisition date, acquisition related gains will no longer be recorded. ASU 2017-01 is required to be adopted for public entities for fiscal years beginning after December 15, 2017. The adoption of this standard did not have a material impact on Kennedy Wilson's consolidated financial statements, except that going forward the Company will no longer record acquisition related gains when acquiring controlling interests in real estate investments that are deemed asset acquisitions. In January 2017, the FASB issued ASU 2017-04, which requires an entity to no longer perform a hypothetical purchase price allocation to measure goodwill impairment. Instead, impairment will be measured using the difference between the carrying amount and the fair value of the reporting unit. ASU 2017-04 is required to be adopted for public entities that are SEC filers, for annual and interim periods in fiscal years beginning after December 15, 2019. T he Company does not expect the ASU to have a significant impact on Kennedy Wilson's consolidated financial statements. In August 2017, the FASB issued ASU 2017-12 that simplifies the application of hedge accounting guidance in current GAAP and improves the reporting of hedging relationships to better portray the economic results of an entity’s risk management activities in its consolidated financial statements. Among the simplification updates, the standard eliminates the requirement in current GAAP to separately recognize periodic hedge ineffectiveness. Mismatches between the changes in value of the hedged item and hedging instrument may still occur but they will no longer be separately reported. The standard requires the presentation of the earnings effect of the hedging instrument in the same income statement line item in which the earnings effect of the hedged item is reported. This ASU is effective for public business entities, for annual and interim periods in fiscal years beginning after December 15, 2018. T he Company does not expect the ASU to have a significant impact on Kennedy Wilson's consolidated financial statements. In February 2018, the FASB issued ASU 2018-02, which allows a reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the Tax Cuts and Jobs Act. This ASU is effective for all entities, for annual and interim periods in fiscal years beginning after December 15, 2018. T he Company does not expect the ASU to have a significant impact on Kennedy Wilson's consolidated financial statements. The FASB did not issue any other ASUs during the first six months of 2018 that the Company expects to be applicable and have a material impact on the Company's financial position or results of operations. RECLASSIFICATIONS—Certain balances included in prior year's financial statements have been reclassified to conform to the current year's presentation.

REAL ESTATE AND IN-PLACE LEASE VALUE	REAL ESTATE AND IN-PLACE LEASE VALUE The following table summarizes Kennedy Wilson's investment in consolidated real estate properties at June 30, 2018 and December 31, 2017 : June 30, December 31, (Dollars in millions) 2018 2017 Land $ 1,450.1 $ 1,509.4 Buildings 4,281.6 4,558.0 Building improvements 558.7 511.2 In-place lease values 391.3 417.3 6,681.7 6,995.9 Less accumulated depreciation and amortization (584.0 ) (552.2 ) Real estate and acquired in place lease values, net of accumulated depreciation and amortization $ 6,097.7 $ 6,443.7 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 a straight-line method over their estimated lives not to exceed 40 years . Acquired in-place lease values are recorded at their estimated fair value and depreciated over their respective weighted-average lease term which was 8.1 years at June 30, 2018 . Consolidated Acquisitions The purchase of property is recorded to land, buildings, building improvements, and intangible lease value (including the value of above-market and below-market leases, acquired in-place lease values) based on their respective estimated fair values. The purchase price approximates the fair value of the properties as acquisitions are transacted with third-party willing sellers. During the six months ended June 30, 2018 , Kennedy Wilson acquired the following consolidated properties: (Dollars in millions) Purchase Price Allocation at Acquisition (1) Location Description Land Building Acquired in place lease values (2) Investment debt NCI KWH Shareholders' Equity Western U.S. Two multifamily properties and one commercial property $ 45.8 $ 80.5 $ 0.6 $ 83.7 $ — $ 43.2 United Kingdom One residential property 4.2 — — — — 4.2 Ireland One multifamily property 11.1 96.0 2.1 61.3 — 47.9 $ 61.1 $ 176.5 $ 2.7 $ 145.0 $ — $ 95.3 (1) Excludes net other assets. (2) Includes above and below market leases in this table. Above and below market leases are part of other assets and accrued expenses and other liabilities. Loans Converted to Real Estate During the six months ended June 30, 2018 , Kennedy Wilson gained control over a pool of loans secured by six hotels located in the United Kingdom that were previously accounted for as loan purchases. The assets and liabilities of these properties were consolidated in Kennedy Wilson's consolidated financial statements at fair value . Gains on Sale of Real Estate During the six months ended June 30, 2018 , Kennedy Wilson recognized the following gains on sale of real estate (dollars in millions): Description Consolidated (1) NCI Net of NCI 15 commercial properties in the United Kingdom, three multifamily properties in Ireland, one residential property in Ireland and one residential property in the Western United States $ 230.0 $ 69.0 $ 161.0 (1) Includes both gain on sale of real estate, and the sale of land and development projects, which is the net of sale of real estate and cost of real estate sold. AXA Joint Venture AXA Investment Managers - Real Assets ("AXA") and the Company entered into a joint venture agreement targeting multifamily assets (also referred to as Private Rented Sector ("PRS")) in Ireland. The AXA Joint Venture commenced with AXA investing in a 50% ownership stake in 1,173 multifamily units across three assets in Dublin, Ireland (“Current JV Assets”) previously held by the Company and a different equity partner (held in 50/50 joint ventures) and consolidated in the Company’s financial statements. The Company continues to hold the remaining 50% ownership interests in the Current JV Assets through its ownership in this new joint venture with AXA. As the Company does not control the new joint venture with AXA, the assets are no longer consolidated and its investment with AXA is accounted for under the equity method. Under ASC Subtopic 610-20, due to the deconsolidation, the Company recognized a gain of $149.3 million through gain on sale of real estate of which the Company's share is $82.5 million . Additionally, as such investments have been sold, the related accumulated other comprehensive income associated with foreign currency translation adjustments and hedge derivative instruments have been recognized in the consolidated statements of operations. The Company has elected the fair value option on its interest in the joint venture and will record the investment at fair value going forward. Guarantees Kennedy Wilson has certain guarantees associated with loans secured by consolidated assets. As of June 30, 2018 , the maximum potential amount of future payments (undiscounted) Kennedy Wilson could be required to make under the guarantees was approximately $53.4 million which is approximately 2% of investment level debt of Kennedy Wilson and its equity partners. The guarantees expire through 2025 , 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 on the Company's evaluation of guarantees under FASB ASC Subtopic 460-10 Estimated Fair Value of Guarantees, the estimated fair value of guarantees made as of June 30, 2018 and December 31, 2017 were immaterial.

Equity Method Investments and Joint Ventures [Abstract]
UNCONSOLIDATED INVESTMENTS	UNCONSOLIDATED INVESTMENTS Kennedy Wilson has a number of joint venture interests, generally ranging from 5% to 50% , that were formed to acquire, manage, develop, service 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 The following table details Kennedy Wilson's investments in joint ventures by investment type and geographic location as of June 30, 2018 : (Dollars in millions) Multifamily Commercial Funds Residential and Other Total Western U.S. $ 184.7 $ 39.9 $ 108.5 $ 184.1 $ 517.2 Ireland 89.6 — — — 89.6 United Kingdom — 6.9 — — 6.9 Total $ 274.3 $ 46.8 $ 108.5 $ 184.1 $ 613.7 The following table details the Company's unconsolidated investments by investment type and geographic location as of December 31, 2017 : (Dollars in millions) Multifamily Commercial Funds Residential and Other Total Western U.S. $ 199.7 $ 42.1 $ 85.3 $ 179.8 $ 506.9 United Kingdom — 9.9 — — 9.9 Japan 2.5 — — — 2.5 Total $ 202.2 $ 52.0 $ 85.3 $ 179.8 $ 519.3 During the six months ended June 30, 2018 , multifamily investments increased due to the new joint venture with AXA described in Note 4 which was offset by the sales of a multifamily property and a multifamily development site in the Western United States. Commercial investments decreased due to the sale of an office property. Fund investments increased due to contributions to Funds V and VI and p erformance-based carried interest allocations which were partially offset by asset sales. Residential and other investments increased due to capital expenditures on active developments which was offset by condominium unit and lot sales. Vintage Housing Holdings ("VHH") The Company owns noncontrolling interests in VHH, a joint venture that holds interests in over 43 partnerships that own multifamily properties via a low-income housing tax credit ("LIHTC") structure in the Western United States. The Company accounts for its investment under the equity method as it does not control the investment. As of June 30, 2018 and December 31, 2017 , the carrying value in VHH was $101.0 million and $114.8 million , respectively. The partnerships generate cash flow through their interests in entities owning multifamily housing that is predominantly structured with LIHTCs. The Company has elected the fair value option on its unconsolidated investment in VHH. The total equity income recognized was $3.9 million and $15.7 million during the three and six months ended June 30, 2018 , respectively, and $1.5 million and $15.6 million , respectively, during three and six months ended June 30, 2017 and was comprised of fair value gains and operating distributions recognized through equity income. Fair value gains recognized through equity income were $2.3 million and $12.1 million for the three and six months ended June 30, 2018 and $12.4 million during the six months ended June 30, 2017 . There were no fair value gains recognized during the three months ended June 30, 2017 . Fair value gains are primarily generated from resyndications in which VHH dissolves an existing partnership and recapitalizes into a new partnership with tax exempt bonds and tax credits which are sold to a new tax credit partner and, in many cases, yields cash back to VHH. Upon resyndication, VHH retains a GP interest in the partnership and receives various future streams of cash flows including; development fees, asset management fees, other GP management fees and distributions from operations. Since the investment is accounted for under the fair value option, operating distributions are recorded as equity income. See Note 6 for additional details. Operating distributions recognized through equity income were $1.6 million and $3.6 million for the three and six months ended June 30, 2018 , respectively, and $1.5 million and $3.2 million for the three and six months ended June 30, 2017 , respectively. Performance fees Effective January 1, 2018, Kennedy Wilson adopted ASC Topic 606 and implemented a change in accounting principle related to performance allocations (commonly referred to as “performance fees”). In connection with the adoption and change in accounting principle, the Company now accounts for performance allocations under the GAAP guidance for equity method investments, presents performance allocations as a component of income from unconsolidated investments, and would present certain incentive fee arrangements, to the extent that the Company has them, separately in its results of operations. All prior periods have been conformed for these changes. The impact of adoption was a reclassification of $32.9 million from other assets to unconsolidated investments on the consolidated balance sheet as of December 31, 2017. During the three and six months ended June 30, 2018 , there was $6.9 million and $17.2 million , respectively, of performance fee allocations recorded as a component of income from unconsolidated investments. During the three and six months ended June 30, 2017 , there was $(2.6) million and $3.9 million , respectively, of performance fee allocations which were previously presented as a component of investment management, property services and research fees and have been reclassified to income from unconsolidated investments in the current year presentation. Contributions to Joint Ventures During the six months ended June 30, 2018 , Kennedy Wilson contributed $125.6 million to joint ventures, of which $89.8 million was related to the AXA Joint Venture and $12.5 million was related to Kennedy Wilson Real Estate Fund VI, LP with the balance to fund the Company's share of development projects, capital expenditures and working capital needs. Distributions from Joint Ventures During the six months ended June 30, 2018 , Kennedy Wilson received $67.3 million in operating and investing distributions from its joint ventures. Operating distributions resulted from operating cash flow generated by the joint venture investments. Investing distributions resulted from the refinancing of property level debt and asset sales. The following table details cash distributions by investment type and geographic location for the six months ended June 30, 2018 : Multifamily Commercial Funds Residential and Other Total (Dollars in millions) Operating Investing Operating Investing Operating Investing Operating Investing Operating Investing Western U.S. $ 16.3 $ 26.8 $ 0.8 $ 2.3 $ 7.3 $ 7.8 $ 0.2 $ 3.5 $ 24.6 $ 40.4 Japan 0.1 2.2 — — — — — — 0.1 2.2 Total $ 16.4 $ 29.0 $ 0.8 $ 2.3 $ 7.3 $ 7.8 $ 0.2 $ 3.5 $ 24.7 $ 42.6 Investing distributions resulted primarily from recapitalizations and the sale of multifamily and commercial properties in the Western United States. Operating distributions resulted from sales distributions in excess of invested basis and operating cash flow generated by the joint venture investments. Consolidation Considerations 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 FASB ASC Topic 810. The Company accounts for joint ventures where it is deemed that the Company does not have control through the equity method of accounting while entities the Company controls are consolidated in Kennedy Wilson's financial statements. Capital Commitments As of June 30, 2018 , Kennedy Wilson had unfulfilled capital commitments totaling $45.3 million to four of its joint ventures, primarily a closed-end fund managed by Kennedy Wilson, under the respective operating agreements. The Company may be called upon to contribute additional capital to joint ventures in satisfaction of such capital commitment obligations.

FAIR VALUE MEASUREMENTS AND THE FAIR VALUE OPTION	FAIR VALUE MEASUREMENTS AND THE FAIR VALUE OPTION 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 June 30, 2018 : (Dollars in millions) Level 1 Level 2 Level 3 Total Unconsolidated investments $ — $ — $ 478.3 $ 478.3 Net currency derivative contracts — (51.6 ) — (51.6 ) Total $ — $ (51.6 ) $ 478.3 $ 426.7 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, 2017 : (Dollars in millions) Level 1 Level 2 Level 3 Total Unconsolidated investments $ — $ — $ 380.7 $ 380.7 Marketable securities 7.5 — — 7.5 Net currency derivative contracts — (100.9 ) — (100.9 ) Total $ 7.5 $ (100.9 ) $ 380.7 $ 287.3 Unconsolidated Investments Kennedy Wilson elected to use the fair value option ("FV Option") for nineteen unconsolidated investments 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 $369.8 million and $295.4 million at June 30, 2018 and December 31, 2017 , respectively, which is included in unconsolidated investments in the accompanying balance sheets. As noted in Note 4, the Company entered into a joint venture agreement targeting multifamily assets in Ireland with AXA. The Company has elected the fair value option on its interest in the joint venture agreement and will record the investment at fair value going forward. There were no changes recorded in the current period. Additionally, Kennedy Wilson records its investments in Kennedy Wilson Real Estate Fund IV, Kennedy Wilson Real Estate Fund V, LP and Kennedy Wilson Real Estate Fund VI, LP (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 $108.5 million and $85.3 million at June 30, 2018 and December 31, 2017 , respectively, which is included in unconsolidated investments in the accompanying consolidated balance sheets. As of June 30, 2018 , Kennedy Wilson had unfunded capital commitments to the Funds in the amount of $40.5 million . In estimating fair value of real estate held by the Funds and the nineteen FV Option investments, the Company considers significant unobservable inputs such as capitalization and discount rates. The following table summarizes the Company's investments in unconsolidated investments held at fair value by type: (Dollars in millions) June 30, 2018 December 31, 2017 FV Option $ 369.8 $ 295.4 Funds 108.5 85.3 Total $ 478.3 $ 380.7 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 three and six months ended June 30, 2018 and 2017 : Three Months Ended June 30, Six Months Ended June 30, (Dollars in millions) 2018 2017 2018 2017 Beginning balance $ 406.9 $ 409.7 $ 380.7 $ 356.7 Unrealized and realized gains 10.9 5.7 39.7 31.6 Unrealized and realized losses (5.3 ) (2.7 ) (7.7 ) (1.0 ) Contributions 101.3 5.0 115.9 25.2 Distributions (35.5 ) (55.4 ) (50.2 ) (74.5 ) Other — (0.4 ) (0.1 ) 23.9 Ending balance $ 478.3 $ 361.9 $ 478.3 $ 361.9 Unobservable Inputs for Real Estate The table below describes the range of unobservable inputs for real estate assets: Estimated Rates Used for Capitalization Rates Discount Rates Office 4.50% - 7.25% 7.00% - 9.00% Retail 5.75% - 9.50% 7.25% - 11.50% Multifamily 4.75% - 7.75% 8.00% - 9.75% Residential N/A 6.00% - 12.00% In valuing indebtedness, the Company 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 1.43% to 3.46% . 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 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 capitalization rates, discount rates, liquidity risks, and estimates of future cash flows, could significantly affect the fair value measurement amounts. Marketable Securities Marketable securities include Kennedy Wilson's investment in publicly traded equity securities and fixed income investments. During the six months ended June 30, 2018 the Company liquidated its marketable security portfolio. The fixed income portfolio consisted mainly of U.S. government and investment grade corporate bonds. The carrying value of marketable securities was a Level 1 valuation as the fair value was based off of unadjusted quoted market prices in active markets for identical securities. Currency Derivative Contracts Kennedy Wilson uses foreign currency derivative contracts such as forward contracts and options to manage its foreign currency risk exposure against the effects of a portion of its certain non-U.S. dollar denominated currency net investments. Foreign currency options are valued using a variant of the Black-Scholes model tailored for currency derivatives and the foreign currency forward contracts are valued based on the difference between the contract rate and the forward rate at maturity of the underlying currency applied to the notional value in the underlying currency discounted at a market rate for similar risks. Although the Company has determined that the majority of the inputs used to value its currency derivative contracts fall within Level 2 of the fair value hierarchy, the counterparty risk adjustments associated with the currency derivative contracts utilize Level 3 inputs. However, as of June 30, 2018 , 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, the Company 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 accumulated other comprehensive income (loss) in the accompanying consolidated statements of comprehensive income (loss) as the portion of the currency forward and option contracts used to hedge currency exposure of its certain consolidated subsidiaries qualifies as a net investment hedge under FASB ASC Topic 815. The fair value of the currency derivative contracts held as of June 30, 2018 and December 31, 2017 are reported in other assets for hedge assets and included in accrued expenses and other liabilities for hedge liabilities on the accompanying balance sheet. The table below details the currency derivative contracts Kennedy Wilson held as of June 30, 2018 and the activity during the six months ended June 30, 2018 . For the six months ended June 30, 2018 Kennedy Wilson had a gross foreign currency translation loss on its net assets of $39.6 million . See Note 11 for a complete discussion on other comprehensive income including currency derivative contracts and foreign currency translations.

Amounts reclassified out of OCI to gain on sale of real estate. (5) Includes $7.9 million of realized gains (losses) associated with hedges related to AXA transaction that are included as part of gain on sale of real estate. The gains recognized through other comprehensive income will remain in accumulated other comprehensive income until the underlying investments that they were hedging are substantially liquidated by Kennedy Wilson. 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 loans (excluding related party loans 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. Debt liabilities are accounted for at face value plus net unamortized debt premiums and any fair value adjustments as part of business combinations. The fair value as of June 30, 2018 and December 31, 2017 for the mortgage, KW unsecured debt, and KWE unsecured bonds were estimated to be approximately $5.6 billion and $5.8 billion , 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 the Company's credit risk to the current yield of a similar security, compared to their carrying value of $5.5 billion and $5.7 billion at June 30, 2018 and December 31, 2017 , respectively. The inputs used to value the Company's mortgage, KW unsecured debt, and KWE unsecured bonds are based on observable inputs for similar assets and quoted prices in markets that are not active and are therefore determined to be Level 2 inputs.

OTHER ASSETS	OTHER ASSETS Other assets consist of the following: (Dollars in millions) June 30, 2018 December 31, 2017 Above-market leases, net of accumulated amortization of $47.8 and $44.3 at June 30, 2018 and December 31, 2017, respectively $ 54.0 $ 63.1 Development project asset 34.9 55.3 Furniture and equipment net of accumulated depreciation of $35.7 and $35.8 at June 30, 2018 and December 31, 2017, respectively 35.8 44.3 Straight line rent 30.7 24.0 Hedge assets 28.9 2.4 Goodwill 23.9 23.9 Prepaid expenses 16.8 13.3 Other, net of accumulated amortization of $2.7 and $2.6 at June 30, 2018 and December 31, 2017, respectively 11.6 10.7 Leasing commissions, net of accumulated amortization of $2.9 and $2.2 at June 30, 2018 and December 31, 2017, respectively 11.0 10.1 Marketable securities — 7.5 VAT receivable 2.8 5.0 Deposits 3.0 3.5 Other Assets $ 253.4 $ 263.1 Development Project Asset On May 12, 2017, Kennedy Wilson and its equity partners (the “Capital Dock JV”) sold 200 Capital Dock, a 130,000 ft. office building under construction in Dublin, Ireland. Concurrently with the transaction, the Capital Dock JV entered into a development agreement with the buyer to complete the construction of 200 Capital Dock. The development agreement provides that upon certain events (including the insolvency of the Capital Dock JV and certain delivery deadlines not being met), the buyer may exercise a right to take over the construction of the project. Because the construction process is not complete, but the cost and profit are reasonably estimated, the Company recognizes revenue on this project under the percentage-of-completion method for the sale of the building. Under the percentage-of-completion method, there was $18.5 million of sale of real estate and $16.4 million of cost of real estate sold reported in the consolidated statement of operations related to the sale of 200 Capital Dock during the six months ended June 30, 2018 . Consequently the "development project asset" represents the basis which has not yet been relieved under the percentage of completion method. The decrease during the period was due to the Company receiving a $38.8 million milestone payment from the buyer. The remaining revenue and cost will be reported under the percentage-of-completion method through completion of construction, which is expected to continue until the third quarter of 2018. In the event that the buyer exercises its right to take over the construction of the project under the circumstances described above, the Capital Dock JV will receive a reduced amount of proceeds from this transaction.

The unamortized loan premium (discount) as of June 30, 2018 and December 31, 2017 was $(5.1) million and $(1.9) million , respectively. Borrowings Under Credit Facilities The Company, through a wholly-owned subsidiary, has a $700 million unsecured revolving credit and term loan facility (the "A&R Facility"). The A&R Facility is comprised of a $500 million revolving line of credit and a $200 million term loan facility. Loans under the revolving line of credit bear interest at a rate equal to LIBOR plus between 1.75% and 2.75% , depending on the consolidated leverage ratio as of the applicable measurement date. Loans under the term loan facility bear interest at a rate equal to LIBOR plus between 1.65% and 2.65% , depending on the consolidated leverage ratio as of the applicable measurement date. The A&R Facility has a maturity date of March 31, 2021. Subject to certain conditions precedent and at Kennedy-Wilson, Inc.’s ("the Borrower") option, the maturity date of the A&R Facility may be extended by one year . The A&R Facility has certain covenants as defined within its Amended and Restated Credit Agreement, dated as of October 20, 2017 (the "Credit Agreement") that, among other things, limit the Company and certain of its subsidiaries’ ability to incur additional indebtedness, repurchase capital stock or debt, sell assets or subsidiary stock, create or permit liens on assets, engage in transactions with affiliates, enter into sale/leaseback transactions, issue subsidiary equity and enter into consolidations or mergers. The Credit Agreement requires the Company to maintain (i) a maximum consolidated leverage ratio (as defined in the Credit Agreement) of not greater than 65% , measured as of the last day of each fiscal quarter, (ii) a minimum fixed charge coverage ratio (as defined in the Credit Agreement) of not less than 1.70 to 1.00 , measured as of the last day of each fiscal quarter for the period of four full fiscal quarters then ended, (iii) a minimum consolidated tangible net worth equal to or greater than the sum of $1,066,775,300 plus an amount equal to fifty percent ( 50% ) of net equity proceeds received by the Company after the date of the most recent financial statements that are available as of the Closing Date, measured as of the last day of each fiscal quarter, (iv) a maximum recourse leverage ratio (as defined in the Credit Agreement) of not greater than an amount equal to consolidated tangible net worth as of the measurement date multiplied by 1.5 , measured as of the last day of each fiscal quarter, (v) a maximum secured recourse leverage ratio (as defined in the Credit Agreement) of not greater than an amount equal to 3.5% of consolidated total asset value (as defined in the Credit Agreement) and $300,351,000 , (vi) a maximum adjusted secured leverage ratio (as defined in the Credit Agreement) of not greater than 55% , measured as of the last day of each fiscal quarter, and (vii) liquidity (as defined in the Credit Agreement) of at least $75.0 million . As of June 30, 2018 , the Company was in compliance with these covenants. During the six months ended June 30, 2018 , the Borrower drew $225.0 million and repaid $400.0 million on the A&R Facility. Of the $400.0 million that was repaid $325.0 million was related to the revolving line of credit and $75.0 million was for the term loan facility. The amount repaid on the term loan facility cannot be drawn again. The maximum amount drawn on the A&R Facility at any one point during the six months ended June 30, 2018 was $375.0 million . As of June 30, 2018 , the Company had an outstanding balance of $125.0 million on the A&R Facility with $500.0 million available to be drawn under the revolving credit facility. The average outstanding borrowings under credit facilities was $248.1 million during the six months ended June 30, 2018 . Senior Notes On March 2, 2018, Kennedy Wilson, Inc., (the "Issuer") completed an additional private offering of $250 million aggregate principal amount of 5.875% Senior Notes due 2024 (the "Notes"). The Notes were issued as additional notes under the indenture pursuant to which the Issuer previously issued $900 million aggregate principal amount of its 5.875% Senior Notes due 2024 (the "Initial Notes"). The Notes have substantially identical terms as the Initial Notes and will be treated as a single series with the Initial Notes under the indenture. The Notes were issued and sold at a cash offering price of 98.625% of their principal amount, plus accrued and unpaid interest from, and including, October 1, 2017. In connection with the March 2018 offering of the Notes, Kennedy Wilson entered into cross-currency swap agreements totaling $200.0 million , effectively reducing the fixed annual cash interest cost to 3.831% per year for five years. The agreements have a five -year tenor and, under the terms of the swap agreements, Kennedy Wilson’s interest payments on $200 million aggregate principal amount of the notes will be effectively converted from U.S. dollars to Euros at an average coupon of 3.319% per annum. Because the swap is managing a pre-existing currency exposure (the overall investment abroad) the accounting will follow foreign currency exchange accounting resulting in recording of other comprehensive income (“OCI”) which will be net against other OCI created by the pre-existing exposures. Consequently, the cross-currency swap will have two entries associated with it each period. The interest savings associated with the lower interest rate on euro amounts will be recorded to OCI. The Company will record interest expense at the contractual amount of 5.875% in the income statement. The interest savings that are recorded through OCI will not be recognized in the income statement until the underlying investment that the forward contracts have been designated to have been substantially liquidated. The indenture governing the Notes contains various restrictive covenants, including, among others, limitations on the Company's ability and the ability of certain of the Company's subsidiaries to incur or guarantee additional indebtedness, make restricted payments, pay dividends or make any other distributions from restricted subsidiaries, redeem or repurchase capital stock, sell assets or subsidiary stocks, engage in transactions with affiliates, create or permit liens on assets, enter into sale/leaseback transactions, and enter into consolidations or mergers. The indenture governing the Notes limits the ability of Kennedy Wilson and its restricted subsidiaries to incur additional indebtedness if, on the date of such incurrence and after giving effect to the new indebtedness, the maximum balance sheet leverage ratio (as defined in the indenture) is greater than 1.50 to 1.00 , subject to certain exceptions. As of June 30, 2018 , the maximum balance sheet leverage ratio was 1.07 to 1.00 . See Note 15 for the guarantor and non-guarantor financial statements.

Debt premiums (discounts) represent the difference between the fair value of debt and the principal value of debt assumed in various acquisitions and are amortized into interest expense over the remaining term of the related debt in a manner that approximates the effective interest method. The unamortized premium (discount) as of June 30, 2018 and December 31, 2017 was $4.0 million and $4.3 million , respectively. KWE has £500 million of 3.95% fixed-rate senior unsecured bonds due 2022 that have a carrying value of $660.2 million and $675.6 million as of June 30, 2018 and December 31, 2017 , respectively. KWE effectively reduced the interest rate to 3.35% as a result of it entering into swap arrangements to convert 50% of the proceeds into Euros. In addition, KWE has a £2.0 billion (approximately $2.6 billion based on June 30, 2018 rates) Euro Medium Term Note ("EMTN") Programme. Under the EMTN Programme, KWE may issue, from time to time, up to £2.0 billion of various types of debt securities in certain markets and currencies. KWE issued senior unsecured notes for an aggregate principal amount of approximately $642.6 million (based on June 30, 2018 rates) ( €550 million ) (the "KWE Notes"). The KWE Notes were issued at a discount and have a carrying value of $639.7 million , with an annual fixed coupon of 3.25% and mature in 2025 . As KWE invests proceeds from the KWE Notes to fund equity investments in new euro denominated assets, KWE designates the KWE Notes as net investment hedges under FASB ASC Topic 815. Subsequent fluctuations in foreign currency rates that impact the carrying value of the KWE Notes are recorded to accumulated other comprehensive income. During the six months ended June 30, 2018 , Kennedy Wilson recognized a gain of $2.4 million in accumulated other comprehensive income due to the weakening of the euro against the GBP during the period. The KWE Notes rank pari passu with the KWE Bonds and are subject to the same restrictive covenants. The trust deed that governs the bonds contains various restrictive covenants for KWE, including, among others, limitations on KWE’s and its material subsidiaries’ ability to provide certain negative pledges. The trust deed limits the ability of KWE and its subsidiaries to incur additional indebtedness if, on the date of such incurrence and after giving effect to the incurrence of the new indebtedness, (1) KWE’s consolidated net indebtedness (as defined in the trust deed) would exceed 60% of KWE’s total assets (as calculated pursuant to the terms of the trust deed); and (2) KWE’s consolidated secured indebtedness (as defined in the trust deed) would exceed 50% of KWE’s total assets (as calculated pursuant to the terms of the trust deed). The trust deed also requires KWE, as of each reporting date, to maintain an interest coverage ratio (as defined in the trust deed) of at least 1.50 to 1.00 and have unencumbered assets of no less than 125% of its unsecured indebtedness (as defined in the trust deed). As of June 30, 2018 , KWE was in compliance with these covenants.

Equity [Abstract]
EQUITY	EQUITY Common Stock Repurchase Program On March 20, 2018, the Company announced a $250.0 million stock repurchase plan authorized by its board of directors. Repurchases under the program may be made in the open market, in privately negotiated transactions, through the net settlement of the Company’s restricted stock grants or otherwise, with the amount and timing of repurchases dependent on market conditions and subject to the company’s discretion. Kennedy Wilson had a $100 million stock repurchase program that expired on February 25, 2018. During the six months ended June 30, 2018 , Kennedy Wilson repurchased and retired 8,286,841 shares for 148.7 million under the stock repurchase program. During the six months ended June 30, 2017 , Kennedy Wilson repurchased and retired 77,155 shares for $1.6 million under the previous stock repurchase program. Dividend Distributions During the following periods, Kennedy Wilson declared and paid the following cash distributions on its common stock: Six Months Ended June 30, 2018 Six Months Ended June 30, 2017 (Dollars in millions) Declared Paid Declared Paid Common Stock (1) $ 56.1 $ 57.5 $ 39.1 $ 37.9 (1) The difference between declared and paid is the amount accrued on the consolidated balance sheets. Share-based Compensation During the three months ended June 30, 2018 and 2017 , Kennedy Wilson recognized $8.8 million and $9.4 million of compensation expense related to the vesting of restricted stock grants. During the six months ended June 30, 2018 and 2017 , Kennedy Wilson recognized $18.7 million and $20.1 million of compensation expense related to the vesting of restricted stock grants. The decrease for the three and six months ended June 30, 2018 is mainly due to shares which fully vested in 2017. Generally, upon vesting, the restricted stock granted to employees is net share-settled such that the Company will withhold shares with value equivalent to the employees’ minimum statutory obligation for the applicable income and other employment taxes, and remit the cash to the appropriate taxing authorities. Only a certain amount of the restricted shares that vested during the six months ended June 30, 2018 were net share settled. The employees' minimum statutory obligation for the restricted shares which were not net share-settled were funded by the employees and remitted to the appropriate taxing authorities. However, all of the restricted shares that vested during 2017 were net-share settled. The total shares withheld during the six months ended June 30, 2018 and 2017 were 380,768 shares and 1,460,251 shares, respectively. During the six months ended June 30, 2018 and 2017 , total payments for the employees’ tax obligations to the taxing authorities for the shares which were net-share settled were $6.8 million and $34.0 million , respectively. These activities are reflected as a financing activity within Kennedy Wilson's consolidated statements of cash flows. Accumulated Other Comprehensive Income The following table summarizes the changes in each component of accumulated other comprehensive loss, net of taxes: (Dollars in millions) Foreign Currency Translation Currency Derivative Contracts Marketable Securities Total Accumulated Other Comprehensive Loss (1) Balance at December 31, 2017 $ (46.6 ) $ (22.2 ) $ 0.1 $ (68.7 ) Unrealized (losses) gains, arising during the period (39.6 ) 28.1 — (11.5 ) Amounts reclassified out of AOCI during the period, gross 22.5 (7.9 ) (0.2 ) 14.4 Amounts reclassified out of AOCI during the period, taxes (4.2 ) 2.8 0.1 (1.3 ) Noncontrolling interest (6.0 ) — — (6.0 ) Deferred taxes on unrealized gains (losses), arising during the period 0.7 (5.9 ) — (5.2 ) Balance at June 30, 2018 $ (73.2 ) $ (5.1 ) $ — $ (78.3 ) (1) As a result of the KWE Transaction the Company was required to record inception to date accumulated other comprehensive losses of $358.4 million associated with noncontrolling interest holders of KWE. This amount has been excluded from the beginning and ending balances of the table to give a more appropriate depiction of the Company's accumulated other comprehensive loss activity. If this amount is included, the accumulated other comprehensive loss is $436.7 million and $427.1 million as of June 30, 2018 and December 31, 2017 , respectively. The local currencies for the Company's interests in foreign operations include the euro and the British pound sterling. The related amounts on Kennedy Wilson's balance sheets are translated into U.S. dollars at the exchange rates at the respective financial statement date, while amounts on its 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 and the British pound during the six months ended June 30, 2018 . The Company is required under U.S. GAAP to consolidate certain non-wholly owned subsidiaries or investments that it controls. As such, the Company's financial statements reflect currency translation adjustments and related hedging activities on a gross basis. It is helpful to look at the provided currency translation and currency derivative adjustment information net of noncontrolling interests to get a more accurate understanding of the actual currency exposure for the Company . In order to manage currency fluctuations, Kennedy Wilson entered into currency derivative contracts to manage its exposure to currency fluctuations between its functional currency (U.S. dollar) and the functional currency (euro and the British pound) of certain of its wholly-owned and consolidated subsidiaries. See Note 6 for a more detailed discussion of Kennedy Wilson's currency derivative contracts. Noncontrolling Interests Noncontrolling interests consist of the ownership interests of noncontrolling shareholders in consolidated subsidiaries and are presented separately on Kennedy Wilson's balance sheet. As of June 30, 2018 and December 31, 2017 , Kennedy Wilson had noncontrolling interest of $179.4 million and $211.9 million , respectively. The decrease in noncontrolling interest for the year is primarily due to the deconsolidation of three properties in the AXA Joint Venture. See Note 4 for additional details.

Earnings Per Share [Abstract]
EARNINGS PER SHARE	EARNINGS PER SHARE In accordance with FASB ASC Topic 260-10-45, Earnings Per Share , the Company uses the two-class method to calculate earnings per share. Basic earnings per share is calculated based on dividends declared (“distributed earnings”) and the rights of common shares and participating securities in any undistributed earnings, which represents net income remaining after deduction of dividends declared during the period. Participating securities, which include unvested restricted stock, are included in the computation of earnings per share pursuant to the two-class method. The undistributed earnings are allocated to all outstanding common shares and participating securities based on the relative percentage of each security to the total number of outstanding securities. Basic earnings per common share and participating securities represent the summation of the distributed and undistributed earnings per common share and participating security divided by the total weighted average number of common shares outstanding and the total weighted average number of participating securities outstanding during the respective periods. The Company only presents the earnings per share attributable to the common shareholders. Net losses, after deducting the dividends to participating securities, are allocated in full to the common shares since the participating security holders do not have an obligation to share in the losses, based on the contractual rights and obligations of the participating securities. The following is a summary of the elements used in calculating basic and diluted income (loss) per share for the three and six months ended June 30, 2018 and 2017 : Three Months Ended June 30, Six Months Ended June 30, (Dollars in millions, except share and per share amounts) 2018 2017 2018 2017 Net income attributable to Kennedy-Wilson Holdings, Inc. common shareholders $ 109.6 $ 9.4 $ 107.2 $ 10.2 Dividends allocated to participating securities (0.8 ) (0.2 ) (0.8 ) (0.5 ) Net income attributable to Kennedy-Wilson Holdings, Inc. common shareholders, net of allocation to participating securities 108.8 9.2 106.4 9.7 Dividends declared on common shares (27.3 ) (19.3 ) (55.6 ) (38.6 ) Undistributed earnings (losses) attributable to Kennedy-Wilson Holdings, Inc. common shareholders, net of allocation to participating securities $ 81.5 $ (10.1 ) $ 50.8 $ (28.9 ) Distributed earnings per share $ 0.19 $ 0.17 $ 0.38 $ 0.34 Undistributed earnings (losses) per share 0.58 (0.09 ) 0.36 (0.25 ) Income per basic and diluted share 0.77 0.08 0.74 0.09 Weighted average shares outstanding for basic 141,483,445 111,723,952 144,696,059 111,945,354 Weighted average shares outstanding for diluted (1) 142,707,159 111,723,952 145,872,617 111,945,354 Dividends declared per common share $ 0.19 $ 0.17 $ 0.38 $ 0.34 (1) For the three and six months ended June 30, 2018 , a total of 1,223,714 and 1,176,558 , respectively, potentially dilutive securities have been included in the diluted weight average shares as they are dilutive. For the three and six months ended June 30, 2017 , a total of 1,040,003 and 989,495 , respectively, potentially dilutive securities have not been included in the diluted weighted average shares as they are anti-dilutive. Potentially anti-dilutive securities include unvested restricted stock grants.

Segment Reporting [Abstract]
SEGMENT INFORMATION	SEGMENT INFORMATION Kennedy Wilson is a global real estate investment company. The Company owns, operates, and invests in real estate both on its own and through our investment management platform. To complement its investment business, the Company also provides real estate services primarily to financial services clients. Kennedy Wilson’s segment disclosure with respect to the determination of segment profit or loss and segment assets is based on these two core segments: KW Investments and KW Investment Management and Real Estate Services (IMRES).

The Company has an average ownership interest across all investments of approximately 66% as of June 30, 2018 . When it has partners, those partners include financial institutions, foundations, endowments, high net worth individuals and other institutional investors. In these instances, the Company is typically the general partner in the arrangement with a promoted interest in the profits of its investments beyond the Company's ownership percentage. These promoted interests are typically fees earned by IMRES as described below.

Income Taxes

Income Taxes	6 Months Ended

Income Tax Disclosure [Abstract]
INCOME TAXES	INCOME TAXES We derive a significant portion of our income from the rental and sale of real property. As a result, a substantial portion of our foreign earnings is subject to U.S. taxation under provisions of SubPart F of the Internal Revenue Code. In determining the quarterly provisions for income taxes, the Company calculates income tax expense based on actual year-to-date income and statutory tax rates. The year-to-date income tax expense reflects the impact of SubPart F inclusions, income allocated to noncontrolling interest which is generally not subject to corporate tax as well as the Company's tax adjustments associated with uncertain tax positions. During the six months ended June 30, 2018 , Kennedy Wilson generated pretax book income of $193.1 million related to its global operations and recorded a tax expense of $26.8 million or 13.9% . The difference between the U.S. federal rate of 21% and the Company's effective rate is primarily attributable to foreign real estate gains not subject to local taxation or not yet includable in U.S. taxes under SubPart F and income allocated to non-controlling interests which is not subject to corporate tax. During the three months ended March 2018, Kennedy Wilson elected to treat KWE as a partnership for U.S. tax purposes retroactive to December 29, 2017. Due to unrealized foreign exchange losses not yet deductible for tax purposes and the consideration paid to acquire the non-controlling interests in KWE exceeding the book carrying value of the non-controlling interests in KWE, the Company’s tax basis in KWE exceeded its book carrying value at December 29, 2017 and at each reporting period thereafter. Prior to the election to treat KWE as a partnership, KWE was taxed as a controlled foreign corporation. As a controlled foreign corporation, the Company was precluded from recognizing a deferred tax asset for its tax basis in excess of book carrying value for its investment in KWE as the excess tax basis from the investment was not expected to reverse in the foreseeable future. However, as a result of the conversion of KWE to a partnership for U.S. tax purposes, the Company was required to record a deferred tax asset of $108.6 million related to its excess tax basis over book carrying value for its investment in KWE. As a significant portion of the excess tax basis would only reverse upon a strengthening of foreign currencies or upon a disposition of KWE or the majority of its assets, the Company determined that a valuation allowance of $108.6 million was required for the tax basis that was in excess of the Company’s carrying value for its investment in KWE. During the three months ended June 30, 2018, the Company recorded an additional deferred tax asset and associated valuation allowance attributable to a decrease in the financial reporting basis in KWE as result of unrealized foreign exchange losses exceeding gains realized from sale of real estate during the quarter. During the quarter, the valuation allowance was reduced by $5.2 million to reflect the tax benefit expected to be realized from the disposition of real estate. As of June 30, 2018, the deferred tax asset and valuation allowance related to the Company’s investment in KWE was $118.9 million and $113.7 million , respectively. U.S. tax reform legislation, commonly referred to as the Tax Cuts and Jobs Act (the “Tax Bill”), was signed into law on December 22, 2017. The Tax Bill amends a range of U.S. federal tax rules applicable to individuals, businesses, and international taxation with most provisions taking effect beginning January 1, 2018. These changes include lowering the federal corporate income tax rate from 35% to 21% and imposing a repatriation tax on deemed repatriated earnings of foreign subsidiaries. Due to the nature of our business operations, a majority of our foreign income is taxed currently in the U.S. For those foreign subsidiaries where there is no current U.S. tax inclusion, we have estimated that no repatriation tax is due as those foreign subsidiaries do not have aggregate positive unrepatriated foreign earnings. We made reasonable estimates of the effects of the Tax Bill and recorded a provisional tax benefit of $44.8 million related to the remeasurement of deferred tax balances as of December 31, 2017 . The Tax Bill contains many new and complex domestic and international tax provisions and state conformity to the new legislation is uncertain. As we gather additional data and review further guidance that might be issued by the Internal Revenue Service, Department of Treasury, or state taxing authorities, our interpretations of the Tax Bill may change resulting in changes to the provisional amounts previously recorded. Those adjustments may materially affect our provision for income taxes and effective tax rate in the period in which the adjustments were made. The adjustments made in the first quarter of 2018 were not significant and no adjustment was made in the second quarter of 2018. The accounting for the tax effects of the Tax Act will be completed later in 2018.

Accounting Policies [Abstract]
REVENUE RECOGNITION	In May 2014, the Financial Accounting Standards Board (“FASB”) issued ASC Topic 606, Revenue from Contracts with Customers, which introduced a new five step model to recognize revenue from customer contracts in an effort to increase consistency and comparability throughout global capital markets and across industries. The model identifies the contract, any separate performance obligations in the contract, determines the transaction price, allocates the transaction price and recognizes revenue when the performance obligations are satisfied. Management has concluded that, with the exception of carried interests and incentive fees, the nature of the Company's revenue streams is such that the requirements are generally satisfied at the time that the fee becomes receivable. Consequently, the new standard did not impact the timing of revenue recognition for these revenue streams . The Company has concluded that carried interests, which are a performance-based capital allocation to the Company based on cumulative fund performance to-date, represent equity method investments that are not in the scope of the amended revenue recognition guidance. Effective January 1, 2018, the Company changed its policy for recognition and measurement of performance fees. This accounting policy change did not change the timing or amount of income recognized related to performance fees. Prior to this accounting method change, the performance-based component of the fees was recognized within investment management, property services and research fees in the Consolidated Statements of Operations. Under the equity method of accounting, the Company now recognizes its allocation of performance fees along with its share of income or loss and fair value, proportionate to the Company’s equity ownership in each applicable investment as a component of income from unconsolidated investments. The Company has accounted for this change by full retrospective application and prior periods presented have been recast. The impact of adoption was a reclassification of $32.9 million from other assets to unconsolidated investments on the consolidated balance sheet as of December 31, 2017. During the three and six months ended June 30, 2018 , there was $6.9 million and $17.2 million of performance-based carried interest allocations recorded as a component of income from unconsolidated investments. During the three and six months ended June 30, 2017 , there was $(2.6) million and $3.9 million of performance fee allocations which were previously presented as a component of investment management, property services and research fees and have been reclassified to income from unconsolidated investments in the current year presentation. ASC Subtopic 610-20, Other Income - Gains and Losses from the Derecognition of Nonfinancial Assets ("Subtopic 610-20") was also adopted effective January 1, 2018. Management concluded that the new standard did not have a significant impact on the amount, timing or classification of real estate sales in the financial statements or related disclosures. This conclusion was based on the Company's current business mix and general approach to sales of real estate which are generally completed without seller financing or continuing involvement that would indicate that a performance obligation is not met at the time the transaction closes. With the adoption of Subtopic 610-20 the Company will recognize the entire gain attributed to contributions of real estate properties to unconsolidated entities. The Company previously recognized a gain on contribution only to the extent of the third-party ownership in the unconsolidated entity acquiring the property and deferred the portion of the gain related to the Company's ownership. The Company’s analysis included evaluation of an in-process development project that will be completed later in 2018 and found that while the evaluation is different under Subtopic 610-20, the recognition required recording the gain on the sale of the land and the development component, as separate performance obligations, under a percentage of completion methodology. However, this conclusion is identical to the manner of reporting the gain on the sale of this real estate under the superseded U.S. GAAP. Consequently, there was no significant impact upon this sale nor any of the other sales already completed.
REAL ESTATE ACQUISITIONS	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). The ownership of the other interest holders in consolidated subsidiaries is reflected as noncontrolling interests. 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 is valued, in part, based on third party valuations and management estimates also using an income approach.
FOREIGN CURRENCIES	The financial statements of Kennedy Wilson's subsidiaries located outside the United States are measured using the local currency as this is their 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 and the British pound sterling. 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. Investment level debt is generally incurred in local currencies. Fluctuations in foreign exchanges rates may have a significant impact on the results of our operations. In order to manage the effect of these fluctuations, the Company enters into hedging transactions, in the form of currency derivative contracts, that are designed to reduce its book equity exposure to foreign currencies.
FAIR VALUE MEASUREMENTS	Kennedy Wilson accounts for fair value measurements of financial assets and financial liabilities and for fair value measurements of non-financial 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.
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.
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. Fluctuations in foreign exchanges rates may have a significant impact on the Company's results of operations. In order to manage the potential exposure from adverse changes in foreign exchange rates arising from the Company’s net investments in foreign operations, the Company may enter into currency derivative contracts to hedge all or portions of the net investments in the Company’s non-U.S. dollar denominated foreign operations.
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 ASC Subtopic 740-10, Accounting for Uncertainty in Income Taxes , the effect of income tax positions is recognized only if those positions are more likely than not to be 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.
RECENT ACCOUNTING PRONOUNCEMENTS	On January 1, 2018, Kennedy Wilson adopted ASC Topic 606 and ASC Subtopic 610-20 transition guidance. See discussion above in revenue recognition for more detail. In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842) , which sets out the principles for the recognition, measurement, presentation and disclosure of leases for both parties to a contract (i.e., lessees and lessors). The new standard requires lessees to apply a dual approach, classifying leases as either finance or operating leases based on the principle of whether or not the lease is effectively a financed purchase by the lessee. This classification will determine whether lease expense is recognized based on an effective interest method or on a straight-line basis over the term of the lease. A lessee is also required to record a right-of-use asset and a lease liability for all leases with a term of greater than 12 months regardless of their classification. Leases with a term of 12 months or less will be accounted for similar to existing guidance for operating leases today. The new standard requires lessors to account for leases using an approach that is substantially equivalent to existing guidance for sales-type leases, direct financing leases and operating leases. ASU 2016-02 is required to be adopted for fiscal years beginning after December 15, 2018. Because Kennedy Wilson's existing operating lease commitments are not material and the accounting for leases by the lessor is substantially unchanged, the Company does not expect the ASU to have a significant impact on its results of operations or financial position. In August 2016, the FASB issued ASU 2016-15, Classification of Certain Cash Receipts and Cash Payments , which addresses eight classification issues related to the statement of cash flows: (a) debt prepayment or debt extinguishment costs, (b) settlement of zero-coupon bonds, (c) contingent consideration payments made after a business combination (d) proceeds from the settlement of insurance claims, (e) proceeds from the settlement of corporate-owned life insurance policies, including bank-owned life insurance policies, (f) distributions received from equity method investees, (g) beneficial interests in securitization transactions, and (h) separately identifiable cash flows and application of the predominance principle. ASU 2016-15 is required to be adopted for public entities for fiscal years beginning after December 15, 2017. The adoption of this standard did not have a material impact on Kennedy Wilson's consolidated financial statements. In January 2017, the FASB issued ASU 2017-01, Business Combinations (Topic 805): Clarifying the Definition of a Business. The ASU clarifies the definition of a business. The three elements of a business (inputs, processes, and outputs) has not changed, however, the amendment provides a framework to assist entities in evaluating whether these elements are present. The amended framework is not expected to materially impact the Company’s financial statements. However, the amendment also includes a provision that when substantially all of the fair value of the gross assets acquired (or disposed of) is concentrated in a single identifiable asset or a group of similar identifiable assets, the set is not a business. Therefore, real estate acquisitions generally will no longer be considered a business and consequently not be accounted for under Topic 805. The Company has evaluated the impact noting that for asset acquisitions (1) acquisition related costs will no longer be expensed as incurred and (2) regardless of the market value of a property at the acquisition date, acquisition related gains will no longer be recorded. ASU 2017-01 is required to be adopted for public entities for fiscal years beginning after December 15, 2017. The adoption of this standard did not have a material impact on Kennedy Wilson's consolidated financial statements, except that going forward the Company will no longer record acquisition related gains when acquiring controlling interests in real estate investments that are deemed asset acquisitions. In January 2017, the FASB issued ASU 2017-04, which requires an entity to no longer perform a hypothetical purchase price allocation to measure goodwill impairment. Instead, impairment will be measured using the difference between the carrying amount and the fair value of the reporting unit. ASU 2017-04 is required to be adopted for public entities that are SEC filers, for annual and interim periods in fiscal years beginning after December 15, 2019. T he Company does not expect the ASU to have a significant impact on Kennedy Wilson's consolidated financial statements. In August 2017, the FASB issued ASU 2017-12 that simplifies the application of hedge accounting guidance in current GAAP and improves the reporting of hedging relationships to better portray the economic results of an entity’s risk management activities in its consolidated financial statements. Among the simplification updates, the standard eliminates the requirement in current GAAP to separately recognize periodic hedge ineffectiveness. Mismatches between the changes in value of the hedged item and hedging instrument may still occur but they will no longer be separately reported. The standard requires the presentation of the earnings effect of the hedging instrument in the same income statement line item in which the earnings effect of the hedged item is reported. This ASU is effective for public business entities, for annual and interim periods in fiscal years beginning after December 15, 2018. T he Company does not expect the ASU to have a significant impact on Kennedy Wilson's consolidated financial statements. In February 2018, the FASB issued ASU 2018-02, which allows a reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the Tax Cuts and Jobs Act. This ASU is effective for all entities, for annual and interim periods in fiscal years beginning after December 15, 2018. T he Company does not expect the ASU to have a significant impact on Kennedy Wilson's consolidated financial statements. The FASB did not issue any other ASUs during the first six months of 2018 that the Company expects to be applicable and have a material impact on the Company's financial position or results of operations.
RECLASSIFICATIONS	Certain balances included in prior year's financial statements have been reclassified to conform to the current year's presentation.
EARNINGS PER SHARE	In accordance with FASB ASC Topic 260-10-45, Earnings Per Share , the Company uses the two-class method to calculate earnings per share. Basic earnings per share is calculated based on dividends declared (“distributed earnings”) and the rights of common shares and participating securities in any undistributed earnings, which represents net income remaining after deduction of dividends declared during the period. Participating securities, which include unvested restricted stock, are included in the computation of earnings per share pursuant to the two-class method. The undistributed earnings are allocated to all outstanding common shares and participating securities based on the relative percentage of each security to the total number of outstanding securities.
