CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS

This report contains forward-looking statements within the meaning of Section 27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934, which reflect our current views with respect to, among other things, our operations and financial performance. You can identify these forward-looking statements by the use of words such as “outlook,” “believe,” “expect,” “potential,” “continue,” “may,” “should,” “seek,” “approximately,” “predict,” “intend,” “will,” “plan,” “estimate,” “anticipate,” the negative version of these words, other comparable words or other statements that do not relate strictly to historical or factual matters. Forward-looking statements are subject to various risks and uncertainties. Accordingly, there are or will be important factors that could cause actual outcomes or results to differ materially from those indicated in these statements. We believe these factors include those described under the section entitled “Risk Factors” in this report. These factors should be read in conjunction with the other cautionary statements that are included in this report and in our other periodic filings. We do not undertake any obligation to publicly update or review any forward-looking statement, whether as a result of new information, future developments or otherwise.

In this report, references to “KKR,” “we,” “us,” “our” and “our partnership” refer to KKR & Co. L.P. and its consolidated subsidiaries. Prior to KKR & Co. L.P. becoming listed on the New York Stock Exchange (“NYSE”) on July 15, 2010, KKR Group Holdings L.P. consolidated the financial results of KKR Management Holdings L.P. and KKR Fund Holdings L.P. (together, the “KKR Group Partnerships”) and their consolidated subsidiaries.

References to “our Managing Partner” are to KKR Management LLC, which acts as our general partner and unless otherwise indicated, references to equity interests in KKR’s business, or to percentage interests in KKR’s business, reflect the aggregate equity of the KKR Group Partnerships and are net of amounts that have been allocated to our principals in respect of the carried interest from KKR’s business as part of our “carry pool” and certain minority interests. References to our “principals” are to our senior employees and non-employee operating consultants who hold interests in KKR’s business through KKR Holdings L.P., which we refer to as “KKR Holdings”, and references to our “senior principals” are to principals who also hold interests in our Managing Partner entitling them to vote for the election of its directors.

Prior to October 1, 2009, KKR’s business was conducted through multiple entities for which there was no single holding entity, but were under common control of senior KKR principals, and in which senior principals and KKR’s other principals and individuals held ownership interests (collectively, the “Predecessor Owners”). On October 1, 2009, we completed the acquisition of all of the assets and liabilities of KKR & Co. (Guernsey) L.P. (f/k/a KKR Private Equity Investors, L.P. or “KPE”) and, in connection with such acquisition, completed a series of transactions pursuant to which the business of KKR was reorganized into a holding company structure. The reorganization involved a contribution of certain equity interests in KKR’s business that were held by KKR’s Predecessor Owners to the KKR Group Partnerships in exchange for equity interests in the KKR Group Partnerships held through KKR Holdings. We refer to the acquisition of the assets and liabilities of KPE and to our subsequent reorganization into a holding company structure as the “KPE Transaction.”

In this report, the term “assets under management,” or “AUM”, represents the assets from which KKR is entitled to receive fees or a carried interest and general partner capital. We believe this measure is useful to unitholders as it provides additional insight into KKR’s capital raising activities and the overall activity in its investment funds and vehicles. KKR calculates the amount of AUM as of any date as the sum of: (i) the fair value of the investments of KKR’s investment funds plus uncalled capital commitments from these funds; (ii) the fair value of investments in KKR’s co-investment vehicles; (iii) the net asset value of certain of KKR’s fixed income products; (iv) the value of outstanding structured finance vehicles and (v) the fair value of other assets managed by KKR. KKR’s definition of AUM is not based on the definitions of AUM that may be set forth in agreements governing the investment funds, vehicles or accounts that it manages and is not calculated pursuant to any regulatory definitions.

In this report, the term “fee paying assets under management,” or “FPAUM”, represents only those assets under management from which KKR receives fees. We believe this measure is useful to unitholders as it provides additional insight into the capital base upon which KKR earns management fees. This relates to KKR’s capital raising activities and the overall activity in its investment funds and vehicles, for only those funds and vehicles where KKR receives fees (i.e., excluding vehicles that receive only carried interest or general partner capital). FPAUM is the sum of all of the individual fee bases that are used to calculate KKR’s fees and differs from AUM in the following respects: (i) assets from which KKR does not receive a fee are excluded (i.e., assets with respect to which it receives only carried interest); and (ii) certain assets, primarily in its private equity funds, are reflected based on capital commitments and invested capital as opposed to fair value because fees are not impacted by changes in the fair value of underlying investments.

In this report, the term “fee related earnings,” or “FRE”, is comprised of segment operating revenues less segment operating expenses and is used by management as an alternative measurement of the operating earnings of KKR and its business segments before investment income. We believe this measure is useful to unitholders as it provides additional insight into the operating profitability of our fee generating management companies and capital markets businesses. The components of FRE on a segment basis differ from the equivalent GAAP amounts on a consolidated basis as a result of: (i) the inclusion of management fees earned from consolidated funds that were eliminated in consolidation; (ii) the exclusion of fees and expenses of certain consolidated entities; (iii) the exclusion of charges relating to the amortization of intangible assets; (iv) the exclusion of charges relating to carry pool allocations; (v) the exclusion of non-cash equity charges and other non-cash compensation charges borne by KKR Holdings or incurred under the KKR & Co. L.P. 2010 Equity Incentive Plan; (vi) the exclusion of certain reimbursable expenses; and (vii) the exclusion of certain non-recurring items.

In this report, the term “economic net income (loss),” or “ENI”, is a measure of profitability for KKR’s reportable segments and is used by management as an alternative measurement of the operating and investment earnings of KKR and its business segments. We believe this measure is useful to unitholders as it provides additional insight into the overall profitability of KKR’s businesses inclusive of investment income and carried interest. ENI is comprised of: (i) FRE; plus (ii) segment investment income (loss), which is reduced for carry pool allocations and management fee refunds; less (iii) certain economic interests in KKR’s segments held by third parties. ENI differs from net income (loss) on a GAAP basis as a result of: (i) the exclusion of the items referred to in FRE above; (ii) the exclusion of investment income (loss) relating to noncontrolling interests; and (iii) the exclusion of income taxes.

In this report, “syndicated capital” is the aggregate amount of debt or equity capital in transactions originated by KKR investment funds and vehicles, which has been distributed to third parties in exchange for a fee. It does not include capital committed to such transactions by carry-yielding co-investment vehicles, which is instead reported in committed dollars invested. Syndicated capital is used as a measure of investment activity for KKR and its business segments during a given period, and we believe that this measure is useful to investors as it provides additional insight into levels of syndication activity in KKR’s Capital Markets and Principal Activities segment and across its investment platform.

You should note that our calculations of AUM, FPAUM, FRE, ENI, syndicated capital and other financial measures may differ from the calculations of other investment managers and, as a result, our measurements of AUM, FPAUM, FRE, ENI, syndicated capital and other financial measures may not be comparable to similar measures presented by other investment managers.  For important information regarding these and other financial measures, please see “Management’s Discussion and Analysis of Financial Condition & Results of Operations—Segment Operating and Performance Measures.”

References to “our funds” or “our vehicles” refer to investment funds, vehicles and/or accounts advised, sponsored or managed by one or more subsidiaries of KKR, unless context requires otherwise.

In this report, the term “GAAP” refers to generally accepted accounting principles in the United States.

Unless otherwise indicated, references in this report to our fully diluted common units outstanding, or to our common units outstanding on a fully diluted basis, reflect (i) actual common units outstanding, (ii) common units into which KKR Group Partnership Units not held by us are exchangeable pursuant to the terms of the exchange agreement described in this report and (iii) common units issuable pursuant to any equity awards actually issued under the KKR & Co. L.P. 2010 Equity Incentive Plan, which we refer to as our “Equity Incentive Plan,” but do not reflect common units available for issuance pursuant to our Equity Incentive Plan for which grants have not yet been made.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of Presentation

The accompanying unaudited condensed consolidated financial statements of KKR & Co. L.P. have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) for interim financial information and the instructions to Form 10-Q. The condensed consolidated financial statements, including these notes, are unaudited and exclude some of the disclosures required in annual financial statements. Management believes it has made all necessary adjustments (consisting of only normal recurring items) such that the condensed consolidated financial statements are presented fairly and that estimates made in preparing the condensed consolidated financial statements are reasonable and prudent. The operating results presented for interim periods are not necessarily indicative of the results that may be expected for any other interim period or for the entire year. The December 31, 2012 condensed consolidated balance sheet data was derived from audited consolidated financial statements included in KKR’s Annual Report on Form 10-K for the year ended December 31, 2012, which include all disclosures required by GAAP. These condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements included in KKR & Co. L.P.’s Annual Report on Form 10-K filed with the Securities and Exchange Commission (“SEC”).

The condensed consolidated financial statements (referred to hereafter as the “financial statements”) include the accounts of KKR’s management and capital markets companies, the general partners of certain unconsolidated funds and vehicles, general partners of consolidated funds and their respective consolidated funds and certain other entities.

KKR & Co. L.P. consolidates the financial results of the KKR Group Partnerships and their consolidated subsidiaries. KKR Holdings’ ownership interest in the KKR Group Partnerships is reflected as noncontrolling interests in the accompanying financial statements.

References in the accompanying financial statements to KKR’s “principals” are to KKR’s senior employees and non-employee operating consultants who hold interests in KKR’s business through KKR Holdings, including those principals who also hold interests in the Managing Partner entitling those principals to vote for the election of the Managing Partners’ directors (the “Senior Principals”).

Use of Estimates

The preparation of the financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of fees, expenses and investment income (loss) during the reporting periods. Such estimates include but are not limited to the valuation of investments and financial instruments. Actual results could differ from those estimates, and such differences could be material to the financial statements.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued)

Consolidation

General

KKR consolidates (i) those entities in which it holds a majority voting interest or has majority ownership and control over significant operating, financial and investing decisions of the entity, including the KKR funds and vehicles in which KKR, as general partner, is presumed to have control, or (ii) entities determined to be variable interest entities (“VIEs”) for which KKR is considered the primary beneficiary.

With respect to KKR’s consolidated funds and vehicles, KKR generally has operational discretion and control, and fund investors have no substantive rights to impact ongoing governance and operating activities of the fund, including the ability to remove the general partner, also known as kick-out rights. As result, a fund should be consolidated unless KKR has a nominal level of equity at risk. To the extent that KKR commits a nominal amount of equity to a given fund and has no obligation to fund any future losses, the equity at risk to KKR is not considered substantive and the fund is typically considered a VIE as described below.  In these cases, the fund investors are generally deemed to be the primary beneficiaries and KKR does not consolidate the fund.  In cases when KKR’s equity at risk is deemed to be substantive, the fund is generally not considered to be a VIE and KKR generally consolidates the fund.

KKR’s funds and vehicles are consolidated by KKR notwithstanding the fact that KKR has only a minority economic interest in those funds. KKR’s financial statements reflect the assets, liabilities, fees, expenses, investment income (loss) and cash flows of the consolidated KKR funds and vehicles on a gross basis, and the majority of the economic interests in those funds, which are held by third party fund investors, are attributed to noncontrolling interests in the accompanying financial statements. All of the management fees and certain other amounts earned by KKR from those funds are eliminated in consolidation. However, because the eliminated amounts are earned from, and funded by, noncontrolling interests, KKR’s attributable share of the net income (loss) from those funds is increased by the amounts eliminated. Accordingly, the elimination in consolidation of such amounts has no effect on net income (loss) attributable to KKR or KKR partners’ capital.

KKR’s funds and vehicles are, for GAAP purposes, investment companies and therefore are not required to consolidate their investments, including investments in portfolio companies, even if majority-owned and controlled. Rather, the KKR funds and vehicles reflect their investments at fair value as described in the Fair Value Measurements section. All intercompany transactions and balances have been eliminated.

Variable Interest Entities

KKR consolidates all VIEs in which it is considered the primary beneficiary. An enterprise is determined to be the primary beneficiary if it has a controlling financial interest under GAAP. A controlling financial interest is defined as (a) the power to direct the activities of a variable interest entity that most significantly impact the entity’s business and (b) the obligation to absorb losses of the entity or the right to receive benefits from the entity that could potentially be significant to the variable interest entity. The consolidation rules which were revised effective January 1, 2010, require an analysis to determine (a) whether an entity in which KKR has a variable interest is a VIE and (b) whether KKR’s involvement, through the holding of equity interests directly or indirectly in the entity or contractually through other variable interests unrelated to the holding of equity interests, would give it a controlling financial interest under GAAP. Performance of that analysis requires the exercise of judgment. Where KKR has an interest in an entity that has qualified for the deferral of the consolidation rules, the analysis is based on consolidation rules prior to January 1, 2010. These rules require an analysis to determine (a) whether an entity in which KKR has a variable interest is a VIE and (b) whether KKR’s involvement, through the holding of equity interests directly or indirectly in the entity or contractually through other variable interests would be expected to absorb a majority of the variability of the entity. Under both guidelines, KKR determines whether it is the primary beneficiary of a VIE at the time it becomes involved with a VIE and reconsiders that conclusion at each reporting date. In evaluating whether KKR is the primary beneficiary, KKR evaluates its economic interests in the entity held either directly by KKR or indirectly through related parties. The consolidation analysis can generally be performed qualitatively; however, if it is not readily apparent that KKR is not the primary beneficiary, a quantitative analysis may also be performed. Investments and redemptions (either by KKR, affiliates of KKR or third parties) or amendments to the governing documents of the respective entities could affect an entity’s status as a VIE or the determination of the primary beneficiary. At each reporting date, KKR assesses whether it is the primary beneficiary and will consolidate or not consolidate accordingly.

(All Dollars are in Thousands, Except Unit, Per Unit Data, and Except Where Noted)

For those unconsolidated VIEs in which KKR is the sponsor, KKR may have an obligation as general partner to provide commitments to such funds. As of March 31, 2013 and December 31, 2012, KKR did not provide any support other than its obligated amount.

KKR’s investment strategies differ by investment fund; however, the fundamental risks have similar characteristics, including loss of invested capital and loss of management fees and carried interests. Accordingly, disaggregation of KKR’s involvement by type of VIE would not provide more useful information.

Business Combinations

Acquisitions are accounted for using the acquisition method of accounting. The purchase price of an acquisition is allocated to the assets acquired and liabilities assumed using the estimated fair values at the acquisition date. Transaction costs are expensed as incurred.

Intangible Assets

Intangible assets consist primarily of contractual rights to earn future fee income, including management and incentive fees, and are included in Other Assets within the statements of financial condition. Identifiable finite-lived intangible assets are amortized on a straight-line basis over their estimated useful lives and amortization expense is included within General, Administrative and Other in the accompanying condensed consolidated statements of operations. Intangible assets are reviewed for impairment when circumstances indicate an impairment may exist. KKR does not have any indefinite-lived intangible assets.

Goodwill

Goodwill represents the excess of acquisition cost over the fair value of net tangible and intangible assets acquired in connection with an acquisition. Goodwill will be assessed for impairment annually or more frequently if circumstances indicate impairment may have occurred. Goodwill is recorded in Other Assets within the condensed consolidated statements of financial condition.

Redeemable Noncontrolling Interests

Redeemable Noncontrolling Interests represent noncontrolling interests of certain investment vehicles and funds that are subject to periodic redemption by fund investors following the expiration of a specified period of time (typically between one and three years), or may be withdrawn subject to a redemption fee during the period when capital may not be otherwise withdrawn. Limited partner interests subject to redemption as described above are presented as Redeemable Noncontrolling Interests within the condensed consolidated statements of financial condition and presented as Net Income (Loss) attributable to Redeemable Noncontrolling Interests within the condensed consolidated statements of operations. When redeemable amounts become legally payable to fund investors, they are classified as a liability and included in Accounts Payable, Accrued Expenses and Other Liabilities in the condensed consolidated statements of financial condition. For all consolidated investment vehicles and funds in which redemption rights have not been granted, noncontrolling interests are presented within Equity in the condensed consolidated statements of financial condition as Noncontrolling Interests.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued)

Noncontrolling Interests

Noncontrolling interests represent (i) noncontrolling interests in consolidated entities and (ii) noncontrolling interests held by KKR Holdings.

Noncontrolling Interests in Consolidated Entities

Noncontrolling interests in consolidated entities represent the non-redeemable ownership interests in KKR that are held primarily by:

(i)                          third party fund investors in KKR’s funds;

(ii)                       a former principal and such person’s designees representing an aggregate of 1% of the carried interest received by the general partners of KKR’s funds and 1% of KKR’s other profits (losses) until a future date;

(iii)                    certain of KKR’s former principals and their designees representing a portion of the carried interest received by the general partners of KKR’s private equity funds that was allocated to them with respect to private equity investments made during such former principals’ previous tenure with KKR;

(iv)                   certain of KKR’s current and former principals representing all of the capital invested by or on behalf of the general partners of KKR’s private equity funds prior to October 1, 2009 and any returns thereon; and

(v)                      a third party in KKR’s capital markets business (representing approximately 2% of the equity in the capital markets business).

Noncontrolling Interests held by KKR Holdings

Noncontrolling interests held by KKR Holdings include economic interests held by KKR’s principals in the KKR Group Partnerships. KKR’s principals receive financial benefits from KKR’s business in the form of distributions received from KKR Holdings and through their direct and indirect participation in the value of KKR Group Partnership Units held by KKR Holdings. These financial benefits are not paid by KKR and are borne by KKR Holdings.

(a)                                  Refer to the table below for calculation of Net income (loss) attributable to noncontrolling interests held by KKR Holdings.

(b)                                  Calculated on a pro rata basis based on the weighted average KKR Group Partnership Units held by KKR Holdings during the reporting period.

(c)                                   Calculated based on the proportion of KKR Holdings units exchanged for KKR & Co. L.P. common units pursuant to the exchange agreement during the reporting period. The exchange agreement provides for the exchange of KKR Group Partnership Units held by KKR Holdings for KKR & Co. L.P. common units.

Net income (loss) attributable to KKR after allocation to noncontrolling interests held by KKR Holdings, with the exception of certain tax assets and liabilities that are directly allocable to KKR Management Holdings Corp., is attributed based on the percentage of the weighted average KKR Group Partnership Units held by KKR and KKR Holdings, each of which hold equity of the KKR Group Partnerships. However, primarily because of the (i) contribution of certain expenses borne entirely by KKR Holdings, (ii) the periodic exchange of KKR Holdings units for KKR & Co. L.P. common units pursuant to the exchange agreement and (iii) the contribution of certain expenses borne entirely by KKR associated with the KKR & Co. L.P. 2010 Equity Plan (“Equity Incentive Plan”), equity allocations shown in the condensed consolidated statement of changes in equity differ from their respective pro-rata ownership interests in KKR’s net assets.

Investments

Investments consist primarily of private equity, real assets, fixed income, equity method and other investments. Investments are carried at their estimated fair values, with unrealized gains or losses resulting from changes in fair value reflected as a component of Net Gains (Losses) from Investment Activities in the condensed consolidated statements of operations. Investments denominated in currencies other than the U.S. dollar are valued based on the spot rate of the respective currency at the end of the reporting period with changes related to exchange rate movements reflected as a component of Net Gains (Losses) from Investment Activities in the condensed consolidated statements of operations. Security and loan transactions are recorded on a trade date basis. Further disclosure on investments is presented in Note 4, “Investments.”

Private Equity —Consists primarily of investments in companies with operating businesses.

Real Assets —Consists primarily of investments in (i) oil and natural gas properties (“natural resources”), (ii) infrastructure assets, and (iii) residential and commercial real estate assets and businesses (“real estate”).

Fixed Income —Consists primarily of investments in below investment grade corporate debt securities (primarily high yield bonds and syndicated bank loans), distressed and opportunistic debt and interests in collateralized loan obligations.

Equity Method —Consists primarily of investments in unconsolidated investment funds and vehicles that are accounted for using the equity method of accounting. Under the equity method of accounting, KKR’s share of earnings (losses) from equity method investments is reflected as a component of Net Gains (Losses) from Investment Activities in the condensed consolidated statements of operations. Because the underlying investments of unconsolidated investment funds and vehicles are reported at fair value, the carrying value of KKR’s equity method investments approximates fair value.

Other —Consists primarily of investments in common stock, preferred stock, warrants and options of companies that are not private equity, real assets or fixed income investments.

Fair Value Measurements

Investments and other financial instruments are measured and carried at fair value. The majority of investments and other financial instruments are held by the consolidated funds and vehicles. KKR’s funds and vehicles are, for GAAP purposes, investment companies and reflect their investments and other financial instruments at fair value. KKR has retained the specialized accounting for the consolidated funds and vehicles in consolidation. Accordingly, the unrealized gains and losses resulting from changes in fair value of the investments held by KKR’s funds and vehicles are reflected as a component of Net Gains (Losses) from Investment Activities in the condensed consolidated statements of operations.

For investments and other financial instruments that are not held in a consolidated fund or vehicle, KKR has elected the fair value option since these investments and other financial instruments are similar to those in the consolidated funds and vehicles. Such election is irrevocable and is applied on an investment by investment basis at initial recognition. Unrealized gains and losses resulting from changes in fair value are reflected as a component of Net Gains (Losses) from Investment Activities in the condensed consolidated statements of operations. The methodology for measuring the fair value of such investments and other financial instruments is consistent with the methodologies applied to investments and other financial instruments that are held in consolidated funds and vehicles.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued)

The carrying amounts of Other Assets, Accounts Payable, Accrued Expenses and Other Liabilities recognized on the statements of financial condition (excluding Fixed Assets, Goodwill, Intangible Assets, contingent consideration and certain debt obligations) approximate fair value due to their short term maturities. Further information on Goodwill and Intangible Assets is presented in Note 14 “Goodwill and Intangible Assets.” Further information on contingent consideration is presented in Note 13 “Acquisitions.” KKR’s debt obligations, except for KKR’s 2020 and 2043 Senior Notes, bear interest at floating rates and therefore fair value approximates carrying value.  Further information on KKR’s 2020 and 2043 Senior Notes are presented in Note 8, “Debt Obligations.” The fair value for KKR’s 2020 and 2043 Senior Notes were derived using Level II inputs similar to those utilized in valuing fixed income investments.

Fair value is 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. Where available, fair value is based on observable market prices or parameters or derived from such prices or parameters. Where observable prices or inputs are not available, valuation techniques are applied. These valuation techniques involve varying levels of management estimation and judgment, the degree of which is dependent on a variety of factors. See Note 5, “Fair Value Measurements” for further information on KKR’s valuation techniques that involve unobservable inputs. Assets and liabilities recorded at fair value in the statements of financial condition are categorized based upon the level of judgment associated with the inputs used to measure their value. Hierarchical levels, as defined under GAAP, are directly related to the amount of subjectivity associated with the inputs to the valuation of these assets and liabilities. The hierarchical levels defined under GAAP are as follows:

Level I

Inputs are unadjusted, quoted prices in active markets for identical assets or liabilities at the measurement date. The type of investments and other financial instruments included in this category are publicly-listed equities and debt and securities sold short.

Level II

Inputs other than quoted prices that are observable for the asset or liability, either directly or indirectly. Level II inputs include quoted prices for similar instruments in active markets, and inputs other than quoted prices that are observable for the asset or liability. The type of investments and other financial instruments included in this category are fixed income investments, convertible debt securities indexed to publicly-listed securities, and certain over-the-counter derivatives.

Level III

Inputs are unobservable for the asset or liability, and include situations where there is little, if any, market activity for the asset or liability. The types of assets and liabilities generally included in this category are private portfolio companies, real assets investments and fixed income investments for which a sufficiently liquid trading market does not exist.

In certain cases, the inputs used to measure fair value may fall into different levels of the fair value hierarchy. In such cases, the level in the fair value hierarchy within which the fair value measurement in its entirety falls has been determined based on the lowest level input that is significant to the fair value measurement in its entirety. KKR’s assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment and consideration of factors specific to the asset.

A significant decrease in the volume and level of activity for the asset or liability is an indication that transactions or quoted prices may not be representative of fair value because in such market conditions there may be increased instances of transactions that are not orderly. In those circumstances, further analysis of transactions or quoted prices is needed, and a significant adjustment to the transactions or quoted prices may be necessary to estimate fair value.

The availability of observable inputs can vary depending on the financial asset or liability and is affected by a wide variety of factors, including, for example, the type of instrument, whether the instrument has recently been issued, whether the instrument is traded on an active exchange or in the secondary market, and current market conditions. To the extent that valuation is based on models or inputs that are less observable or unobservable in the market, the determination of fair value requires more judgment. Accordingly, the degree of judgment exercised by KKR in determining fair value is greatest for instruments categorized in Level III. The variability and availability of the observable inputs affected by the factors described above may cause transfers between Levels I, II, and III, which KKR recognizes at the beginning of the reporting period.

Investments and other financial instruments that have readily observable market prices (such as those traded on a securities exchange) are stated at the last quoted sales price as of the reporting date. KKR does not adjust the quoted price for these investments, even in situations where KKR holds a large position and a sale could reasonably affect the quoted price.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued)

Level II Valuation Methodologies

Financial assets and liabilities categorized as Level II consist primarily of securities indexed to publicly-listed securities and fixed income and other investments. Fixed income investments generally have bid and ask prices that can be observed in the marketplace. Bid prices reflect the highest price that KKR and others are willing to pay for an asset. Ask prices represent the lowest price that KKR and others are willing to accept for an asset. For financial assets and liabilities whose inputs are based on bid-ask prices obtained from third party pricing services, fair value may not always be a predetermined point in the bid-ask range. KKR’s policy is to allow for mid-market pricing and adjusting to the point within the bid-ask range that meets KKR’s best estimate of fair value. For securities indexed to publicly listed securities, such as convertible debt, the securities are typically valued using standard convertible security pricing models. The key inputs into these models that require some amount of judgment are the credit spreads utilized and the volatility assumed. To the extent the company being valued has other outstanding debt securities that are publicly-traded, the implied credit spread on the company’s other outstanding debt securities would be utilized in the valuation. To the extent the company being valued does not have other outstanding debt securities that are publicly-traded, the credit spread will be estimated based on the implied credit spreads observed in comparable publicly-traded debt securities. In certain cases, an additional spread will be added to reflect an illiquidity discount due to the fact that the security being valued is not publicly-traded. The volatility assumption is based upon the historically observed volatility of the underlying equity security into which the convertible debt security is convertible and/or the volatility implied by the prices of options on the underlying equity security.

Level III Valuation Methodologies

Financial assets and liabilities categorized as Level III consist primarily of the following:

Private Equity Investments:     KKR generally employs two valuation methodologies when determining the fair value of a private equity investment. The first methodology is typically a market comparables analysis that considers key financial inputs and recent public and private transactions and other available measures. The second methodology utilized is typically a discounted cash flow analysis, which incorporates significant assumptions and judgments. Estimates of key inputs used in this methodology include the weighted average cost of capital for the investment and assumed inputs used to calculate terminal values, such as exit EBITDA multiples. Other inputs are also used.

Upon completion of the valuations conducted using these methodologies, a weighting is ascribed to each method, and an illiquidity discount is typically applied where appropriate. The ultimate fair value recorded for a particular investment will generally be within a range suggested by the two methodologies.

When determining the weighting ascribed to each valuation methodology, KKR considers, among other factors, the availability of direct market comparables, the applicability of a discounted cash flow analysis and the expected hold period and manner of realization for the investment. These factors can result in different weightings among investments in the portfolio and in certain instances may result in up to a 100% weighting to a single methodology. Across the Level III private equity investment portfolio, approximately 86% of the fair value is derived from investments that are valued based exactly 50% on market comparables and 50% on a discounted cash flow analysis. Less than 5% of the fair value of the Level III private equity investment portfolio is derived from investments that are valued either based 100% on market comparables or 100% on a discounted cash flow analysis.

When determining the illiquidity discount to be applied, KKR takes a uniform approach across its portfolio and generally applies a minimum 5% discount to all private equity investments. KKR then evaluates such private equity investments to determine if factors exist that could make it more challenging to monetize the investment and, therefore, justify applying a higher illiquidity discount. These factors generally include (i) whether KKR is unable to sell the portfolio company or conduct an initial public offering of the portfolio company due to the consent rights of a third party or similar factors, (ii) whether the portfolio company is undergoing significant restructuring activity or similar factors and (iii) characteristics about the portfolio company regarding its size and/or whether the portfolio company is experiencing, or expected to experience, a significant decline in earnings. These factors generally make it less likely that a portfolio company would be sold or publicly offered in the near term at a price indicated by using just a market multiples and/or discounted cash flow analysis, and these factors tend to reduce the number of opportunities to sell an investment and/or increase the time horizon over which an investment may be monetized. Depending on the applicability of these factors, KKR determines the amount of any incremental illiquidity discount to be applied above the 5% minimum, and during the time we hold the investment, the illiquidity discount may be increased or decreased, from time to time, based on changes to these factors. The amount of illiquidity discount applied at any time requires considerable judgment about what a market participant would consider and is based on the facts and circumstances of each individual investment. Accordingly, the illiquidity discount ultimately considered by a market participant upon the realization of any investment may be higher or lower than that estimated by KKR in its valuations.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued)

Real Assets Investments:   For natural resources and infrastructure investments, KKR generally utilizes a discounted cash flow analysis, which incorporates significant assumptions and judgments. Estimates of key inputs used in this methodology include the weighted average cost of capital for the investment and assumed inputs used to calculate terminal values, such as exit EBITDA multiples. For real estate investments, KKR generally utilizes a combination of direct income capitalization and discounted cash flow analysis, which incorporates significant assumptions and judgments. Estimates of key inputs used in these methodologies include an unlevered discount rate and terminal capitalization rate. The valuations of real assets investments also use other inputs. Certain investments in real estate and natural resources generally do not include a minimum illiquidity discount.

Fixed Income Investments:     Fixed income investments are valued using values obtained from dealers or market makers, and where these values are not available, fixed income investments are valued by KKR using internally developed valuation models. Valuation models are based on discounted cash flow analyses, for which the key inputs are determined based on market comparables, which incorporate similar instruments from similar issuers.

Other Investments:     KKR generally employs the same valuation methodologies as described above for private equity investments when valuing these other investments.

Key unobservable inputs that have a significant impact on KKR’s Level III investment valuations as described above are included in Note 5 “Fair Value Measurements.” KKR utilizes several unobservable pricing inputs and assumptions in determining the fair value of its Level III investments. These unobservable pricing inputs and assumptions may differ by investment and in the application of KKR’s valuation methodologies. KKR’s reported fair value estimates could vary materially if KKR had chosen to incorporate different unobservable pricing inputs and other assumptions or, for applicable investments, if KKR only used either the discounted cash flow methodology or the market comparables methodology instead of assigning a weighting to both methodologies.

Level III Valuation Process

The valuation process involved for Level III measurements for private equity, real assets, fixed income, and other investments is completed on a quarterly basis and is designed to subject the valuation of Level III investments to an appropriate level of consistency, oversight, and review. KKR has a Private Markets valuation committee for private equity and real assets investments and a valuation committee for fixed income and other investments. The Private Markets valuation committee may be assisted by subcommittees for example in the valuation of natural resources, infrastructure and real estate investments. Each of the Private Markets valuation committee and the fixed income valuation committee is assisted by a valuation team, which, except as noted below, is comprised only of employees who are not investment professionals responsible for preparing preliminary valuations or for oversight of any of the investments being valued. The valuation teams for natural resources, infrastructure and real estate investments contain investment professionals who participate in the preparation of preliminary valuations and oversight for those investments. The valuation committees and teams are responsible for coordinating and consistently implementing KKR’s quarterly valuation policies, guidelines and processes. For investments classified as Level III, investment professionals prepare preliminary valuations based on their evaluation of financial and operating data, company specific developments, market valuations of comparable companies and other factors. These preliminary valuations are reviewed with the investment professionals by the applicable valuation team and are also reviewed by an independent valuation firm engaged by KKR to perform certain procedures in order to assess the reasonableness of KKR’s valuations for all Level III investments, except for certain investments other than KKR private equity investments. All preliminary valuations are then reviewed by the applicable valuation committee, and after reflecting any input by their respective valuation committees, the preliminary valuations are presented to a single committee consisting of Senior Principals involved in various aspects of the KKR business. When these valuations are approved by this single committee after reflecting any input from it, the valuations of Level III investments, as well as the valuations of Level I and Level II investments, are presented to the audit committee of KKR’s board of directors and are then reported on to the board of directors.

Derivatives

Derivative contracts include forward, swap and option contracts related to foreign currencies and credit standing of reference entities to manage foreign exchange risk and credit risk arising from certain assets and liabilities. All derivatives are recognized in Other Assets or Accounts Payable, Accrued Expenses and Other Liabilities and are presented gross in the condensed consolidated statements of financial condition and measured at fair value with changes in fair value recorded in Net Gains (Losses) from Investment Activities in the accompanying condensed consolidated statements of operations. KKR’s derivative financial instruments contain credit risk to the extent that its counterparties may be unable to meet the terms of the agreements. KKR attempts to minimize this risk by limiting its counterparties to major financial institutions with strong credit ratings.

Recently Issued Accounting Pronouncements

Disclosures About Offsetting Assets and Liabilities

In December 2011 , the FASB issued ASU 2011-11, “Disclosures about Offsetting Assets and Liabilities” (“ASU 2011-11”), which requires entities to disclose information about offsetting and related arrangements of financial instruments and derivative instruments. In February 2013, the FASB issued ASU 2013-01, which clarifies which instruments and transactions are subject to the offsetting disclosure requirements established by ASU 2011-11. ASU 2011-11 was effective for KKR’s fiscal year beginning January 1, 2013 and was applied retrospectively.  The adoption of this guidance did not have a material impact on KKR’s financial statements.

Disclosures About Reclassification Adjustments Out of Accumulated Other Comprehensive Income

In February 2013, the FASB issued ASU 2013-02, “Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income (“AOCI”),” which requires entities to disclose additional information about reclassification adjustments, including: (i) changes in AOCI balances by component and (ii) significant items reclassified out of AOCI. ASU 2013-02 was effective for KKR’s fiscal year beginning January 1, 2013. The adoption of this guidance, which is related to disclosure only, did not have a material impact on KKR’s financial statements. With respect to KKR, AOCI is comprised of only one component, foreign currency translation adjustments and for the three months ended March 31, 2013 and 2012, there were no items reclassified out of AOCI. See KKR’s condensed consolidated statements of comprehensive income and changes in equity.

Foreign Currency Matters

In March 2013, the FASB issued ASU 2013-05, “Foreign Currency Matters,” which indicates that the entire amount of a cumulative translation adjustment (“CTA”) related to an entity’s investment in a foreign entity should be released when there has been a (i) sale of a subsidiary or group of net assets within a foreign entity and the sale represents the substantially complete liquidation of the investment in the foreign entity, (ii) loss of a controlling financial interest in an investment in a foreign entity, or (iii) step acquisition for a foreign entity.  This guidance is effective for KKR’s fiscal year beginning January 1, 2014, and is to be applied prospectively. The adoption of this guidance is not expected to have a material impact on KKR’s financial statements.

3. NET GAINS (LOSSES) FROM INVESTMENT ACTIVITIES

Net Gains (Losses) from Investment Activities in the condensed consolidated statements of operations consist primarily of the realized and unrealized gains and losses on investments (including foreign exchange gains and losses attributable to foreign denominated investments and related activities) and other financial instruments, including those for which the fair value option has been elected. Unrealized gains or losses result from changes in the fair value of these investments and other financial instruments during a period. Upon disposition of an investment or financial instrument, previously recognized unrealized gains or losses are reversed and an offsetting realized gain or loss is recognized in the current period.

The following table summarizes total Net Gains (Losses) from Investment Activities for the three months ended March 31, 2013 and 2012, respectively:

(a)            See Note 4 “Investments.”

(b)            See Note 7 “Other Assets and Accounts Payable, Accrued Expenses and Other Liabilities.”

(c)            See Note 15 “Commitments and Contingencies.”

Equity Method

Equity method investments include certain investments in private equity and real assets funds, funds of hedge funds, and alternative credit funds, which are not consolidated, but in which KKR is deemed to exert significant influence for accounting purposes.  See Note 3 “Net Gains (Losses) from Investment Activities” for the net changes in fair value associated with these investments.

KKR evaluates each of its equity method investments to determine if any were significant as defined by guidance from the United States Securities and Exchange Commission (“SEC”). As of and for the three months ended March 31, 2013 and 2012, KKR’s equity method investments did not meet the significance criteria either on an individual or group basis. As such, presentation of separate financial statements for any of its equity method investments or summarized financial information on an individual or group basis is not required.
