Accounting Policies [Abstract]
Significant Accounting Policies	Significant Accounting Policies For a further discussion of the Company's accounting policies, refer to the Company's Annual Report on Form 10-K for the year ended December 31, 2017. Basis of Presentation – The accompanying unaudited condensed consolidated financial statements of the Company have been prepared in accordance with the instructions to Form 10-Q. As permitted by the rules and regulations of the United States Securities and Exchange Commission, the unaudited condensed consolidated financial statements contain certain condensed financial information and exclude certain footnote disclosures normally included in audited consolidated financial statements prepared in accordance with accounting principles generally accepted in the United States of America ("U.S. GAAP"). The accompanying condensed consolidated financial statements are unaudited and are prepared in accordance with U.S. GAAP. In the opinion of the Company's management, the accompanying unaudited condensed consolidated financial statements contain all adjustments, including normal recurring accruals, necessary to fairly present the accompanying unaudited condensed consolidated financial statements. These unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements included in the Company's annual report on Form 10-K for the year ended December 31, 2017. The December 31, 2017 Unaudited Condensed Consolidated Statement of Financial Condition data was derived from audited consolidated financial statements, but does not include all disclosures required by U.S. GAAP. Operating results for the interim periods are not necessarily indicative of the results that may be expected for the fiscal year ending December 31, 2018. The accompanying unaudited condensed consolidated financial statements of the Company are comprised of the consolidation of Evercore LP and Evercore LP's wholly-owned and majority-owned direct and indirect subsidiaries, including Evercore Group L.L.C. ("EGL"), a registered broker-dealer in the U.S. The Company's policy is to consolidate all subsidiaries in which it has a controlling financial interest, as well as any variable interest entities ("VIEs") where the Company is deemed to be the primary beneficiary, when it has the power to make the decisions that most significantly affect the economic performance of the VIE and has the obligation to absorb significant losses or the right to receive benefits that could potentially be significant to the VIE. The Company reviews factors, including the rights of the equity holders and obligations of equity holders to absorb losses or receive expected residual returns, to determine if the investment is a VIE. In evaluating whether the Company is the primary beneficiary, the Company evaluates its economic interests in the entity held either directly or indirectly by the Company. The consolidation analysis is generally performed qualitatively. This analysis, which requires judgment, is performed at each reporting date. Evercore LP is a VIE and the Company is the primary beneficiary. Specifically, the Company has the majority economic interest in Evercore LP and has decision making authority that significantly affects the economic performance of the entity while the limited partners have no kick-out or substantive participating rights. The assets and liabilities of Evercore LP represent substantially all of the consolidated assets and liabilities of the Company with the exception of U.S. corporate taxes and related items, which are presented on the Company's (Parent Company Only) Condensed Statements of Financial Position in Note 23 to the Company's consolidated financial statements in the Company's Annual Report on Form 10-K for the year ended December 31, 2017. International Strategy & Investment (U.K.) Limited ("ISI U.K.") and Evercore Partners International LLP ("Evercore U.K.") are also VIEs and the Company is the primary beneficiary of these VIEs. Specifically for ISI U.K., the Company provides financial support through a transfer pricing agreement with this entity, which exposes the Company to losses that are potentially significant to the entity, and has decision making authority that significantly affects the economic performance of the entity. The Company has the majority economic interest in Evercore U.K. and has decision making authority that significantly affects the economic performance of this entity. The Company included in its Unaudited Condensed Consolidated Statements of Financial Condition ISI U.K. and Evercore U.K. assets of $96,871 and liabilities of $68,714 at June 30, 2018 and assets of $126,078 and liabilities of $102,487 at December 31, 2017. All intercompany balances and transactions with the Company's subsidiaries have been eliminated upon consolidation. The Company adopted ASU No. 2014-09, "Revenue from Contracts with Customers" ("ASU 2014-09") on January 1, 2018 using the modified retrospective method of transition. The Company did not have a cumulative-effect adjustment as of the date of adoption. Following the adoption of ASU 2014-09, the Company’s accounting policies are as follows: ASU 2014-09 provides a five step model to revenue recognition: Step 1: Identify the contract(s) with a customer Step 2: Identify the performance obligations in the contract Step 3: Determine the transaction price Step 4: Allocate the transaction price to the performance obligations in the contract Step 5: Recognize revenue when (or as) the entity satisfies a performance obligation The Company applies this model to its Investment Banking and Asset Management revenue streams. Investment Banking Revenue - The Company earns investment banking fees from clients for providing advisory services on strategic matters, including mergers, acquisitions, divestitures, leveraged buyouts, restructurings, activism and defense and similar corporate finance matters. The Company's Investment Banking services also include services related to securities underwriting, private placement services and commissions for agency-based equity trading services and equity research. Revenue is recognized as the Company satisfies performance obligations, upon transfer of control of promised services to customers in an amount that reflects the consideration the Company expects to receive in exchange for these services. The Company’s contracts with customers may include promises to transfer multiple services to a customer. Determining whether services are considered distinct performance obligations that should be accounted for separately versus together may require significant judgment. For performance obligations satisfied over time, determining a measure of progress requires the Company to make significant judgments that affect the timing of revenue recognized. For certain advisory services, the Company has concluded that performance obligations are satisfied over time. This is based on the premise that the Company transfers control of services and the client simultaneously receives benefits from these services over the course of an engagement. For performance obligations satisfied at a point in time, determining when control transfers requires the Company to make significant judgments that affect the timing of when revenue is recognized. The Company records Investment Banking Revenue on the Unaudited Condensed Consolidated Statements of Operations for the following: Advisory Fees - In general, advisory fees are paid at the time the Company signs an engagement letter, during the course of the engagement or when an engagement is completed. In some circumstances, and as a function of the terms of an engagement letter, the Company may receive fixed retainer fees for financial advisory services concurrent with, or soon after, the execution of the engagement letter or over the course of the engagement, where the engagement letter will specify a future service period associated with those fees. The Company may also receive announcement fees upon announcement of a transaction in addition to success fees upon closing of a transaction or another defined outcome, both of which represent variable consideration. This variable consideration will be included in the transaction price, as defined, to the extent that it is probable that a significant reversal of revenue will not occur. With respect to retainer, announcement and success fees, there are no distinct performance obligations aside from advisory activities, which are generally focused on achieving a milestone (typically, the announcement and/or the closing of a transaction). These advisory services are provided over time throughout the contract period. The Company will recognize revenue when distinct services are performed and when it is probable that a reversal of revenue will not occur, which is generally upon the announcement or closing of a transaction. In circumstances in which retainer fees are received in advance of services, these fees are initially recorded as deferred revenue (a contract liability), which is recorded in Other Current Liabilities on the Unaudited Condensed Consolidated Statements of Financial Condition, and subsequently recognized as advisory fee revenue in Advisory Fees on the Unaudited Condensed Consolidated Statements of Operations during the applicable time period within which the service is rendered. Announcement fees for advisory services are recognized upon announcement (the point at which it is determined that the reversal of revenue is not probable) and all other requirements for revenue recognition are satisfied. A portion of the announcement fee may be deferred based on the services remaining to be completed, if any. Success fees for advisory services, such as merger and acquisition advice, are recognized when it is determined that the reversal of revenue is not probable and all other requirements for revenue recognition are satisfied, which is generally at closing of the transaction. With respect to fairness or valuation opinions, fees are fixed and there is a distinct performance obligation, since the opinion is rendered separate from any other advisory activities. Revenues related to fairness or valuation opinions are recognized at the point in time when the opinion has been rendered and delivered to the client. In the event the Company was to receive an opinion or success fee in advance of the completion conditions noted above, such fee would initially be recorded as deferred revenue (a contract liability) in Other Current Liabilities on the Unaudited Condensed Consolidated Statements of Financial Condition and subsequently recognized as advisory fee revenue in Advisory Fees on the Unaudited Condensed Consolidated Statements of Operations when the conditions of completion have been satisfied. Placement fee revenues are attributable to capital raising on both corporations and financial sponsors. The Company recognizes placement fees in accordance with the terms of the engagement letter, which are generally contingent on the achievement of a capital commitment by an investor, at the time of the client's acceptance of capital or capital commitments. Underwriting Fees - Underwriting fees are attributable to public and private offerings of equity and debt securities and are recognized at the point in time when the offering has been deemed to be completed by the lead manager of the underwriting group. When the offering is completed, the performance obligation has been satisfied and the Company recognizes the applicable management fee, selling concession and underwriting fee. Estimated offering expenses are presented gross in the Unaudited Condensed Consolidated Statements of Operations. Commissions and Related Fees - Commissions and Related Fees include commissions received from customers for the execution of agency-based brokerage transactions in listed and over-the-counter equities. The execution of each trade order represents a distinct performance obligation and the transaction price at the point in time of trade order execution is fixed. Trade execution is satisfied at the point in time that the customer has control of the asset and as such, fees are recorded on a trade date basis or, in the case of payments under commission sharing arrangements, when earned. The Company also earns subscription fees for the sales of research. The delivery of research under subscription arrangements represents a distinct performance obligation that is satisfied over time. The fees are fixed and are recognized over the period in which the performance obligation is satisfied. Cash received before the subscription period ends is initially recorded as deferred revenue (a contract liability) in Other Current Liabilities on the Unaudited Condensed Consolidated Statements of Financial Condition, and is recognized in Commissions and Related Fees on the Unaudited Condensed Consolidated Statements of Operations ratably over the period in which the related services are rendered. Taxes collected from customers and remitted to governmental authorities are presented on a net basis on the Consolidated Statements of Operations. Asset Management and Administration Fees - The Company's Investment Management business generates revenues from the management of client assets and through interests in private equity funds which are not managed by the Company. The Company’s contracts with customers may include promises to transfer multiple services to a customer. Determining whether services are considered distinct performance obligations that should be accounted for separately versus together may require significant judgment. For performance obligations satisfied over time, determining a measure of progress requires the Company to make significant judgments that affect the timing of revenue recognized. Asset management fees for third-party clients are generally based on the value of the assets under management and any performance fees that may be negotiated with the client. The management of asset portfolios represents a distinct performance obligation that is satisfied over time. These fees are generally recognized over the period that the related services are provided and in which the performance obligation is satisfied, based upon the beginning, ending or average value of the assets for the relevant period. Fees paid in advance of services rendered are initially recorded as deferred revenue (a contract liability), which is recorded in Other Current Liabilities on the Unaudited Condensed Consolidated Statements of Financial Condition, and are recognized in Asset Management and Administration Fees on the Unaudited Condensed Consolidated Statements of Operations ratably over the period in which the related service is rendered. Generally, to the extent performance fee arrangements have been negotiated, these fees are earned when the likelihood of clawback is mathematically improbable. Fees generated for serving as an independent fiduciary and/or trustee are either based on a flat fee, are pre-negotiated with the client or are based on the value of assets under administration. The management of assets under administration represents a distinct performance obligation that is satisfied over time. For ongoing engagements, fees are billed quarterly either in advance or in arrears. Fees paid in advance of services rendered and satisfaction of the performance obligation are initially recorded as deferred revenue (a contract liability) in Other Current Liabilities on the Unaudited Condensed Consolidated Statements of Financial Condition, and are recognized in Asset Management and Administration Fees on the Unaudited Condensed Consolidated Statements of Operations ratably over the period in which the related services are rendered and the performance obligation is satisfied. The Company records performance fee revenue from the private equity funds when the returns on the private equity funds' investments exceed certain threshold minimums. These performance fees, or carried interest, are computed in accordance with the underlying private equity funds' partnership agreements and are based on investment performance over the life of each investment partnership. The Company records performance fees upon the earlier of the termination of the investment fund or when the likelihood of clawback is mathematically improbable. Accounts Receivable and Contract Assets - Accounts Receivable consists primarily of investment banking fees and expense reimbursements charged to the Company's clients. The Company records Accounts Receivable, net of any allowance for doubtful accounts, when relevant revenue recognition criteria has been achieved and payment is conditioned on the passage of time. The Company maintains an allowance for doubtful accounts to provide coverage for estimated losses from its client receivables. The Company determines the adequacy of the allowance by estimating the probability of loss based on the Company's analysis of the client's creditworthiness and specifically reserves against exposure where the Company determines the receivables are impaired, which may include situations where a fee is in dispute or litigation has commenced. The Investment Banking and Investment Management receivables collection periods generally are within 90 days of invoice, with the exception of placement fees, which are generally collected within 180 days of invoice, and fees related to private funds capital raising, which are collected in a period exceeding one year. The collection period for restructuring transactions and private equity fee receivables may exceed 90 days. Receivables that are collected in a period exceeding one year are reflected in Other Assets on the Unaudited Condensed Consolidated Statement of Financial Condition. The Company records contract assets within Other Current Assets on the Unaudited Condensed Consolidated Statement of Financial Condition when payment is due from a client conditioned on future performance or the occurrence of other events. The Company also recognizes a contract asset for the incremental costs of obtaining a contract with a customer if the benefit of those costs is expected to be longer than one year. The Company applies a practical expedient to expense costs to obtain a contract as incurred when the amortization period is one year or less. Reclassifications - During 2018, certain balances on the Unaudited Condensed Consolidated Statements of Operations for the prior period were reclassified to conform to their current presentation. Execution, Clearing and Custody Fees - Other Operating Expenses of $3,363 and $6,889 for the three and six months ended June 30, 2017, respectively, and Professional Fees of $295 and $628 for the three and six months ended June 30, 2017, respectively, were reclassified to a new expense line item "Execution, Clearing and Custody Fees" on the Unaudited Condensed Consolidated Statements of Operations. Other Revenue, Including Interest and Investments - The Company renamed "Other Revenue, Including Interest" to "Other Revenue, Including Interest and Investments" on the Unaudited Condensed Consolidated Statements of Operations and reclassified ($253) and ($263) of principal trading losses from Investment Banking Revenue for the three and six months ended June 30, 2017, respectively, and ($1,589) and ($525) of net realized and unrealized losses on private equity investments from Investment Management Revenue for the three and six months ended June 30, 2017, respectively, to "Other Revenue, Including Interest and Investments." Investment Banking Revenue - Following the above reclassification, the Company disaggregated "Investment Banking Revenue" into "Advisory Fees," "Underwriting Fees" and "Commissions and Related Fees" on the Unaudited Condensed Consolidated Statements of Operations. Asset Management and Administration Fees - Following the above reclassification, the Company has renamed "Investment Management Revenue" to "Asset Management and Administration Fees" on the Unaudited Condensed Consolidated Statements of Operations, which includes management fees from the wealth management and institutional asset management businesses.

Accounting Changes and Error Corrections [Abstract]
Recent Accounting Pronouncements	Recent Accounting Pronouncements ASU 2014-09 – In May 2014, the Financial Accounting Standards Board ("FASB") issued ASU 2014-09. ASU 2014-09 provides amendments to ASC 605, "Revenue Recognition" and creates ASC 606, "Revenue from Contracts with Customers," which changes the requirements for revenue recognition and amends the disclosure requirements. In August 2015, the FASB issued ASU No. 2015-14, "Deferral of the Effective Date," which provides amendments that defer the effective date of ASU 2014-09 by one year. In April 2016, the FASB issued ASU No. 2016-10, "Identifying Performance Obligations and Licensing," which provides clarification to identifying performance obligations and the licensing implementation guidance in ASU 2014-09. In May 2016, the FASB issued ASU No. 2016-12, "Narrow-Scope Improvements and Practical Expedients," which provides clarification on certain issues identified in the guidance on assessing collectability, presentation of sales taxes, noncash consideration, and completed contracts and contract modifications at transition in ASU 2014-09. The amendments in these updates are effective either retrospectively to each prior reporting period presented, or as a cumulative-effect adjustment as of the date of adoption, during interim and annual periods beginning after December 15, 2017, with early adoption permitted beginning after December 15, 2016. The Company adopted ASU 2014-09 on January 1, 2018 using the modified retrospective method of transition, which requires a cumulative-effect adjustment as of the date of adoption. The Company did not have a cumulative-effect adjustment as of the date of adoption. Following the adoption of ASU 2014-09, success related advisory fees, for which payment is generally dependent on the closing of a strategic transaction, a financing arrangement or some other defined outcome, are considered variable consideration as defined by the standard. ASU 2014-09 requires that revenue be recognized when it is probable that variable consideration will not be reversed in a future period. Accordingly, revenue recognition for such fees could be accelerated under ASU 2014-09 in rare circumstances, which will require careful analysis and judgment. Under legacy U.S. GAAP, the Company recognized such fees upon closing regardless of the probability of the outcome. The effect of the timing of revenue recognition could be material to any given reporting period. Furthermore, legacy U.S. GAAP allowed expenses related to underwriting transactions to be reflected net in related revenues. Under ASU 2014-09, those expenses are presented gross in the results of operations. See Notes 2 and 4 for further information. ASU 2016-01 - In January 2016, the FASB issued ASU No. 2016-01, "Recognition and Measurement of Financial Assets and Financial Liabilities" ("ASU 2016-01"). ASU 2016-01 provides amendments to ASC 825, "Financial Instruments," which change the requirements for certain aspects of recognition, measurement and presentation of financial assets and liabilities and amend the disclosure requirements. The amendments in this update are effective during interim and annual periods beginning after December 15, 2017. The amendments in this update should be applied by means of a cumulative-effect adjustment to the balance sheet as of the beginning of the fiscal year of adoption and the amendments related to equity securities without readily determinable fair values should be applied prospectively. The Company adopted ASU 2016-01 on January 1, 2018, which resulted in a cumulative effect adjustment of cumulative unrealized losses, net of tax, on available-for-sale equity securities included in Accumulated Other Comprehensive Income (Loss) to Retained Earnings of ($2,229). Following the adoption of ASU 2016-01, unrealized gains and losses on these securities are recorded in Other Revenue, Including Interest and Investments, on the Unaudited Condensed Consolidated Statements of Operations. The Company also holds equity securities without readily determinable fair values, which were accounted for under the cost method of accounting under legacy U.S. GAAP. Following the adoption of ASU 2016-01, the Company elected to measure each of its former cost method investments at its cost minus impairment, if any, plus or minus changes resulting from observable price changes in orderly transactions for the identical or a similar investment of the same issuer. See Notes 7 and 9 for further information. ASU 2016-02 - In February 2016, the FASB issued ASU No. 2016-02, "Leases (Topic 842)" ("ASU 2016-02"). ASU 2016-02 supersedes ASC 840, "Leases," and includes requirements for the recognition of a right-of-use asset and lease liability on the balance sheet by lessees for those leases classified as operating leases under previous guidance. The amendments in this update are effective using a modified retrospective approach at the beginning of the earliest period presented, during interim and annual periods beginning after December 15, 2018, with early adoption permitted. The Company anticipates adopting ASU 2016-02 on January 1, 2019 using the modified retrospective approach. The Company is in the process of evaluating its lease agreements under ASU 2016-02, including its lease agreement to expand its New York headquarters signed on July 1, 2018. See Note 16 for further information. The adoption will result in the present value of the Company's lease commitments which have a term in excess of one year being reflected on the Company's Statements of Financial Condition as a long-term asset with a corresponding long-term liability. The Company's lease commitments primarily relate to office space, as discussed in Note 16 and in Note 18 to the Company's consolidated financial statements in the Company's Annual Report on Form 10-K for the year ended December 31, 2017. The impact on the Company's earnings is not expected to be materially different from the current expense related to leases as required under legacy U.S. GAAP, which is primarily reflected in Occupancy and Equipment Rental expense on the Unaudited Condensed Consolidated Statements of Operations. ASU 2016-13 - In June 2016, the FASB issued ASU No. 2016-13, "Measurement of Credit Losses on Financial Instruments" ("ASU 2016-13"). ASU 2016-13 provides amendments to ASC 326, "Financial Instruments - Credit Losses," which amend the guidance on the impairment of financial instruments and adds an impairment model (the current expected credit loss (CECL) model) that is based on expected losses rather than incurred losses. Entities will recognize an allowance for its estimate of expected credit losses as of the end of each reporting period. The amendments in this update are effective during interim and annual periods beginning after December 15, 2019, with early adoption permitted after December 15, 2018. The Company currently uses the specific identification method for establishing credit provisions and write-offs of its trade accounts receivable. The Company anticipates adopting ASU 2016-13 on January 1, 2020 and does not anticipate a material difference between the current method and the CECL model. ASU 2016-15 - In August 2016, the FASB issued ASU No. 2016-15, "Classification of Certain Cash Receipts and Cash Payments" ("ASU 2016-15"). ASU 2016-15 provides amendments to ASC 230, "Statement of Cash Flows," ("ASC 230") which provide guidance on the classification of certain cash receipts and payments in the statement of cash flows. The amendments in this update are effective retrospectively, or prospectively, if retrospective application is impracticable, during interim and annual periods beginning after December 15, 2017, with early adoption permitted. The adoption of ASU 2016-15 did not have a material impact on the Company's financial condition, results of operations and cash flows, or disclosures thereto. ASU 2016-18 - In November 2016, the FASB issued ASU No. 2016-18, "Restricted Cash" ("ASU 2016-18"). ASU 2016-18 provides amendments to ASC 230, which require that a statement of cash flows explain the change during the period in the total of cash, cash equivalents and amounts generally described as restricted cash and restricted cash equivalents. The amendments in this update are effective retrospectively during interim and annual periods beginning after December 15, 2017, with early adoption permitted. The adoption of ASU 2016-18 resulted in restricted cash balances being included in the Unaudited Condensed Consolidated Statements of Cash Flows and expanded disclosure on these restricted cash balances. See Note 16 for further information. ASU 2017-01 - In January 2017, the FASB issued ASU No. 2017-01, "Clarifying the Definition of a Business" ("ASU 2017-01"). ASU 2017-01 provides amendments to ASC 805, "Business Combinations," which clarify the definition of a business with the objective of adding guidance to assist entities with evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. The amendments in this update are effective prospectively during interim and annual periods beginning after December 15, 2017, with early adoption permitted. The adoption of ASU 2017-01 did not have a material impact on the Company's financial condition, results of operations and cash flows, or disclosures thereto. ASU 2017-09 - In May 2017, the FASB issued ASU No. 2017-09, "Scope of Modification Accounting" ("ASU 2017-09"). ASU 2017-09 provides amendments to ASC 718, "Compensation - Stock Compensation," ("ASC 718") which provide guidance and clarity around which changes to the terms or conditions of a share-based payment award require an entity to apply modification accounting. The amendments in this update are effective prospectively during interim and annual periods beginning after December 15, 2017, with early adoption permitted. The adoption of ASU 2017-09 did not have a material impact on the Company's financial condition, results of operations and cash flows, or disclosures thereto. ASU 2018-02 - In February 2018, the FASB issued ASU No. 2018-02, "Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income" ("ASU 2018-02"). ASU 2018-02 provides amendments to ASC 220, “Income Statement - Reporting Other Comprehensive Income,” which allow a reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the Tax Cuts and Jobs Act. The amendments in this update are effective either in the period of adoption or retrospectively, to each period (or periods) in which the effect of the change in the U.S. federal corporate income tax rate in the Tax Cuts and Jobs Act is recognized, during interim and annual periods beginning after December 15, 2018, with early adoption permitted. The Company is currently assessing the impact of this update on the Company's financial condition, results of operations and cash flows, or disclosures thereto. ASU 2018-05 - In March 2018, the FASB issued ASU No. 2018-05, "Amendments to SEC Paragraphs Pursuant to SEC Staff Accounting Bulletin No. 118" ("ASU 2018-05"). ASU 2018-05 adds various SEC paragraphs to ASC 740, “Income Taxes,” ("ASC 740") pursuant to the issuance of SEC Staff Accounting Bulletin No. 118 ("SAB 118"). The amendments in this update were effective upon issuance. See Note 18 for further information. ASU 2018-07 - In June 2018, the FASB issued ASU No. 2018-07, "Improvements to Nonemployee Share-Based Payment Accounting" ("ASU 2018-07"). ASU 2018-07 provides amendments to ASC 718 to align the accounting for share-based payment awards issued to employees and nonemployees, particularly surrounding the measurement date and impact of performance conditions. The amendments in this update are effective during interim and annual periods beginning after December 15, 2018, with early adoption permitted. The amendments in this update should be applied by means of a cumulative-effect adjustment to retained earnings as of the beginning of the fiscal year of adoption for liability-classified awards that have not been settled and equity-classified awards for which a measurement date has not been established by the date of adoption, and prospectively for all new awards granted after the date of adoption. The Company is currently assessing the impact of this update on the Company's financial condition, results of operations and cash flows, or disclosures thereto.

Business Developments, Special Charges and Intangible Asset Amortization	6 Months Ended

Business Combinations [Abstract]
Acquisition and Transition Costs and Special Charges	Business Developments, Special Charges and Intangible Asset Amortization Business Developments Real Estate Capital Advisory - On April 23, 2018, the Company announced the expansion of its global investment banking platform by establishing a Real Estate Capital Advisory business within its existing PCA business. This business is focused on secondary transactions for real estate oriented financial sponsors and private equity investors in conjunction with PCA’s existing fund monetization and recapitalization expertise. Certain RECA employees purchased interests in PCA, at fair value, resulting in an increase to Noncontrolling Interest of $770 on the Company's Unaudited Condensed Consolidated Statement of Financial Condition as of June 30, 2018. See Note 13 for further information. In conjunction with the establishment of the RECA business, the Company hired certain employees and entered into an arrangement with the former employer of these employees, which, among other things, provides for contingent consideration to be paid to the former employer of up to $4,463, based on the completion of certain client engagements. The Company accounted for this transaction as an asset acquisition and will recognize the contingent consideration paid as an expense in Professional Fees on the Company's Unaudited Condensed Consolidated Statements of Operations as the related revenue from the underlying engagements is realized. As of June 30, 2018, $1,033 was recognized pursuant to this arrangement. The Company is the general partner of PCA. Concurrent with this transaction, the Company performed an assessment under ASC 810, "Consolidation," ("ASC 810"), and concluded that PCA remains a VIE following this transaction and determined that the Company is still the primary beneficiary of this VIE. Specifically, the Company's general partner interest provides the Company with the ability to make decisions that significantly impact the economic performance of PCA, while the limited partners do not possess substantive participating rights over PCA. The Company's assessment of the primary beneficiary included assessing which parties have the power to significantly impact the economic performance and the obligation to absorb losses, which could be potentially significant to the entity, or the right to receive benefits from the entity that could be potentially significant. The assets of PCA are not generally available to the Company and the liabilities are generally non-recourse to the Company. Special Charges The Company recognized $1,897 for the six months ended June 30, 2018, as Special Charges incurred related to separation benefits and costs for the termination of certain contracts associated with closing the Company's agency trading platform in the U.K. The Company recognized $21,507 for the three and six months ended June 30, 2017, as Special Charges incurred related to an impairment charge of $7,107 associated with the impairment of goodwill in the Company's Institutional Asset Management reporting unit and an impairment charge of $14,400 associated with the impairment of the Company's investment in G5 Holdings S.A. ("G5"). Intangible Asset Amortization Expense associated with the amortization of intangible assets for Investment Banking was $2,190 and $4,380 for the three and six months ended June 30, 2018, respectively, and $2,357 and $4,714 for the three and six months ended June 30, 2017, respectively, included within Depreciation and Amortization expense on the Unaudited Condensed Consolidated Statements of Operations. Expense associated with the amortization of intangible assets for Investment Management was $109 and $218 for the three and six months ended June 30, 2018, respectively, and $118 and $236 for the three and six months ended June 30, 2017, respectively, included within Depreciation and Amortization expense on the Unaudited Condensed Consolidated Statements of Operations.

Since the Company has the ability and intent to hold available-for-sale securities until a recovery of fair value is equal to an amount approximating its amortized cost, which may be at maturity, and has not incurred credit losses on its securities, it does not consider such unrealized loss positions to be other-than-temporarily impaired at June 30, 2018.

Financial Instruments Owned and Pledged as Collateral at Fair Value, Securities Purchased Under Agreements to Resell and Securities Sold Under Agreements to Repurchase

The Company, through Evercore Casa de Bolsa, S.A. de C.V. ("ECB"), enters into repurchase agreements with clients seeking overnight money market returns whereby ECB transfers to the clients Mexican government securities in exchange for cash and concurrently agrees to repurchase the securities at a future date for an amount equal to the cash exchanged plus a stipulated premium or interest factor. ECB deploys the cash received from, and acquires the securities deliverable to, clients under these repurchase arrangements by purchasing securities in the open market, which the Company reflects as Financial Instruments Owned and Pledged as Collateral at Fair Value on the Unaudited Condensed Consolidated Statements of Financial Condition, or by entering into reverse repurchase agreements with unrelated third parties. The Company accounts for these repurchase and reverse repurchase agreements as collateralized financing transactions, which are carried at their contract amounts, which approximate fair value given that the contracts mature the following business day. The Company records a liability on its Unaudited Condensed Consolidated Statements of Financial Condition in relation to repurchase transactions executed with clients as Securities Sold Under Agreements to Repurchase. The Company records as assets on its Unaudited Condensed Consolidated Statements of Financial Condition, Financial Instruments Owned and Pledged as Collateral at Fair Value (where the Company has acquired the securities deliverable to clients under these repurchase arrangements by purchasing securities in the open market) and Securities Purchased Under Agreements to Resell (where the Company has acquired the securities deliverable to clients under these repurchase agreements by entering into reverse repurchase agreements with unrelated third parties). These Mexican government securities had an estimated average time to maturity of approximately 1.5 years, as of June 30, 2018, and are pledged as collateral against repurchase agreements. Generally, collateral is posted equal to the contract value at inception and is subject to market changes. These repurchase agreements are primarily with institutional customer accounts managed by ECB and permit the counterparty to pledge the securities.

ECB has procedures in place to monitor the daily risk limits for positions taken, as well as the credit risk based on the collateral pledged under these agreements against their contract value from inception to maturity date. The daily risk measure is Value at Risk ("VaR"), which is a statistical measure, at a 98% confidence level, of the potential daily losses from adverse market movements in an ordinary market environment based on a historical simulation using the prior year's historical data. ECB's Risk Management Committee (the "Committee") has established a policy to maintain VaR at levels below 0.1% of the value of the portfolio. If at any point in time the threshold is exceeded, ECB personnel are alerted by an automated interface with ECB's trading systems and begin to make adjustments in the portfolio in order to mitigate the risk and bring the portfolio in compliance. Concurrently, ECB personnel must notify the Committee of the variance and the actions taken to reduce the exposure to loss.

In addition to monitoring VaR, ECB periodically performs discrete stress tests ("Stress Tests") to assure that the level of potential losses that would arise from extreme market movements that may not be anticipated by VaR measures are within acceptable levels.

As of June 30, 2018 and December 31, 2017, a summary of the Company's assets, liabilities and collateral received or pledged related to these transactions was as follows:



	June 30, 2018						December 31, 2017

Investments in Private Equity

Private Equity Funds

The Company's investments related to private equity partnerships and associated entities include investments in Evercore Capital Partners II, L.P. ("ECP II"), Glisco Partners II, L.P. ("Glisco II"), Glisco Partners III, L.P. ("Glisco III"), Trilantic Capital Partners Associates IV, L.P. ("Trilantic IV") and Trilantic Capital Partners V, L.P. ("Trilantic V"). Portfolio holdings of the private equity funds are carried at fair value. Accordingly, the Company reflects its pro rata share of the unrealized gains and losses occurring from changes in fair value. Additionally, the Company reflects its pro rata share of realized gains, losses and carried interest associated with any investment realizations.

On December 31, 2014, ECP II was terminated. The Company's investment at June 30, 2018 of $776 is comprised of its remaining interest in the general partner, including $765 in cash and $11 in securities.

A summary of the Company's investment in the private equity funds as of June 30, 2018 and December 31, 2017 was as follows:



	June 30, 2018		December 31, 2017
ECP II	$	776	$	833
Glisco II and Glisco III	4,127		6,558
Trilantic IV and Trilantic V	5,760		6,421
Total Private Equity Funds	$	10,663	$	13,812

Net realized and unrealized gains (losses) on private equity fund investments were ($204) and $142 for the three and six months ended June 30, 2018, respectively, and ($2,532) and ($2,193) for the three and six months ended June 30, 2017, respectively. During the six months ended June 30, 2018, Glisco II, Trilantic IV and Trilantic V made distributions of $2,011, $194 and $997, respectively. In the event the funds perform poorly, the Company may be obligated to repay certain carried interest previously distributed. As of June 30, 2018, there was no previously distributed carried interest received from the Company's managed funds that was subject to repayment.

General Partners of Private Equity Funds which are VIEs

The Company has concluded that Evercore Partners II, L.L.C. ("EP II L.L.C."), the general partner of ECP II, is a VIE pursuant to ASC 810. The Company owned 8%-9% of the carried interest earned by the general partner of ECP II. The Company's assessment of the design of EP II L.L.C. resulted in the determination that the Company is not acting as an agent for other members of the general partner and is a passive holder of interests in the fund, evidenced by the fact that the Company is a non-voting, non-managing member of the general partner and, therefore, has no authority in directing the management operations of the general partner. Furthermore, the Company does not have the obligation to absorb significant losses or the right to receive benefits that could potentially have a significant impact to EP II L.L.C. Accordingly, the Company has concluded that it is not the primary beneficiary of EP II L.L.C. and has not consolidated EP II L.L.C. in the Company's unaudited condensed consolidated financial statements.

Following the Glisco transaction, the Company concluded that Glisco Capital Partners II, Glisco Capital Partners III and Glisco Manager Holdings LP are VIEs and that the Company is not the primary beneficiary of these VIEs. The Company's assessment of the primary beneficiary of these entities included assessing which parties have the power to significantly impact the economic performance of these entities and the obligation to absorb losses, which could be potentially significant to the entities, or the right to receive benefits from the entities that could be potentially significant. Neither the Company nor its related parties will have the ability to make decisions that significantly impact the economic performance of these entities. Further, as a limited partner in these entities, the Company does not possess substantive participating rights. The Company had assets of $6,208 and $8,730 included in its Unaudited Condensed Consolidated Statements of Financial Condition at June 30, 2018 and December 31, 2017, respectively, related to these unconsolidated VIEs, representing the carrying value of the Company's investments in the entities. The Company's exposure to the obligations of these VIEs is generally limited to its investments in these entities. The Company's maximum exposure to loss as of June 30, 2018 and December 31, 2017 was $8,721 and $10,996, respectively, which represents the carrying value of the Company's investments in these VIEs, as well as any unfunded commitments to the current and future funds.

Investment in Trilantic Capital Partners

In 2010, the Company made a limited partnership investment in Trilantic in exchange for 500 Class A limited partnership units of Evercore LP ("Class A LP Units") having a fair value of $16,090. This investment gave the Company the right to invest in Trilantic's current and future private equity funds, beginning with Trilantic Fund IV. The Company accounts for this investment at its cost minus impairment, if any, plus or minus changes resulting from observable price changes. The Company allocates the cost of this investment to its investments in current and future Trilantic funds as the Company satisfies the capital calls of these funds. The Company bases this allocation on its expectation of Trilantic's future fundraising ability and performance. During the six months ended June 30, 2018, $417 of this investment was allocated to Trilantic Fund V. From 2010 to 2017, $4,513 and $1,178 of this investment was allocated to Trilantic Fund V and IV, respectively. This investment had a balance of $9,982 and $10,399 as of June 30, 2018 and December 31, 2017, respectively. The Company has a $5,000 commitment to invest in Trilantic Fund V, of which $683 was unfunded at June 30, 2018. The Company and Trilantic anticipate that the Company will participate in the successor funds to Trilantic Fund V. The Company further anticipates that participation in the successor fund will be at approximately $12,000.

Other Investments

In 2015, the Company received an equity security in a private company in exchange for advisory services. This investment is accounted for at its cost minus impairment, if any, plus or minus changes resulting from observable price changes and had a balance of $1,079 as of June 30, 2018 and December 31, 2017.

Following the Glisco transaction in 2016, the Company recorded an investment in Glisco Manager Holdings LP representing the fair value of the deferred consideration resulting from this transaction. This investment is accounted for at its cost minus impairment, if any, plus or minus changes resulting from observable price changes. The Company amortizes the balance of its investment as distributions are received related to the deferred consideration. This investment had a balance of $2,082 and $2,172 as of June 30, 2018 and December 31, 2017, respectively.

Fair Value Measurements

Fair Value Disclosures [Abstract]

Fair Value Measurements

ASC 820, "Fair Value Measurements and Disclosures" ("ASC 820") establishes a hierarchical disclosure framework which prioritizes and ranks the level of market price observability used in measuring investments at fair value. Market price observability is affected by a number of factors, including the type of investment and the characteristics specific to the investment. Investments with readily-available active quoted prices or for which fair value can be measured from actively quoted prices generally will have a higher degree of market price observability and a lesser degree of judgment used in measuring fair value.

Investments measured and reported at fair value are classified and disclosed in one of the following categories:

Level I – Quoted prices are available in active markets for identical investments as of the reporting date. The type of investments included in Level I include listed equities, listed derivatives and treasury bills. As required by ASC 820, the Company does not adjust the quoted price for these investments, even in situations where the Company holds a large position and a sale could reasonably impact the quoted price.

Level II – Pricing inputs are other than quoted prices in active markets, which are either directly or indirectly observable as of the reporting date, and fair value is determined through the use of models or other valuation methodologies. The estimated fair values of the Corporate Bonds, Municipal Bonds, Other Debt Securities and Securities Investments held at June 30, 2018 and December 31, 2017 are based on prices provided by external pricing services.

Level III – Pricing inputs are unobservable for the investment and includes situations where there is little, if any, market activity for the investment. The inputs into the determination of fair value require significant management judgment or estimation.

The following table presents the categorization of investments and certain other financial assets measured at fair value on a recurring basis as of June 30, 2018 and December 31, 2017:

(1)	Includes $29,215 and $10,354 of treasury bills, municipal bonds and commercial paper classified within Cash and Cash Equivalents on the Unaudited Condensed Consolidated Statements of Financial Condition as of June 30, 2018 and December 31, 2017, respectively.


(2)	Includes $4,138 and $3,092 of treasury bills and notes and municipal bonds classified within Cash and Cash Equivalents on the Unaudited Condensed Consolidated Statements of Financial Condition as of June 30, 2018 and December 31, 2017, respectively.

In certain cases, the inputs used to measure fair value may fall into different levels of the fair value hierarchy. In such cases, an investment's level within the fair value hierarchy is based on the lowest level of input that is significant to the fair value measurement. The Company's assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment, and considers factors specific to the investment.

The Company had no transfers between fair value levels during for the six months ended June 30, 2018 or the year ended December 31, 2017.

On March 30, 2016, the Company issued an aggregate of $170,000 of senior notes, including: $38,000 aggregate principal amount of its 4.88% Series A senior notes due 2021 (the "Series A Notes"), $67,000 aggregate principal amount of its 5.23% Series B senior notes due 2023 (the "Series B Notes"), $48,000 aggregate principal amount of its 5.48% Series C senior notes due 2026 (the "Series C Notes") and $17,000 aggregate principal amount of its 5.58% Series D senior notes due 2028 (the "Series D Notes" and together with the Series A Notes, the Series B Notes and the Series C Notes, the "Private Placement Notes"), pursuant to a note purchase agreement (the "Note Purchase Agreement") dated as of March 30, 2016, among the Company and the purchasers party thereto in a private placement exempt from registration under the Securities Act of 1933.

Interest on the Private Placement Notes is payable semi-annually and the Private Placement Notes are guaranteed by certain of the Company's domestic subsidiaries. The Company may, at its option, prepay all, or from time to time any part of, the Private Placement Notes (without regard to Series), in an amount not less than 5% of the aggregate principal amount of the Private Placement Notes then outstanding at 100% of the principal amount thereof plus an applicable "make-whole amount." Upon the occurrence of a change of control, the holders of the Private Placement Notes will have the right to require the Company to prepay the entire unpaid principal amounts held by each holder of the Private Placement Notes plus accrued and unpaid interest to the prepayment date. The Note Purchase Agreement contains customary covenants, including financial covenants requiring compliance with a maximum leverage ratio, a minimum tangible net worth and a minimum interest coverage ratio, and customary events of default. As of June 30, 2018, the Company was in compliance with all of these covenants.

The Company used $120,000 of the net proceeds from the Private Placement Notes to repay outstanding borrowings under the senior credit facility with Mizuho Bank, Ltd. ("Mizuho") on March 30, 2016 and used the remaining net proceeds for general corporate purposes.

Notes Payable is comprised of the following as of June 30, 2018 and December 31, 2017:

(a)

The Company has outstanding Class J limited partnership units of Evercore LP ("Class J LP Units"), which convert into Class E limited partnership units of Evercore LP ("Class E LP Units") and ultimately become exchangeable into Class A Shares on a one-for-one basis. During the three and six months ended June 30, 2018 and 2017, the Class J LP Units were dilutive and consequently the effect of their exchange into Class A Shares has been included in the calculation of diluted net income per share attributable to Evercore Inc. common shareholders under the if-converted method. In computing this adjustment, the Company assumes that all Class J LP Units are converted into Class A Shares.

(b)

The Company also has outstanding Class A and E LP Units in Evercore LP, which give the holders the right to receive Class A Shares upon exchange on a one-for-one basis. During the three and six months ended June 30, 2018 and 2017, the Class A and E LP Units were antidilutive and consequently the effect of their exchange into Class A Shares has been excluded from the calculation of diluted net income per share attributable to Evercore Inc. common shareholders. The units that would have been included in the denominator of the computation of diluted net income per share attributable to Evercore Inc. common shareholders if the effect would have been dilutive were 5,132 and 5,179 for the three and six months ended June 30, 2018, respectively, and 6,005 and 6,051 for the three and six months ended June 30, 2017, respectively. The adjustment to the numerator, diluted net income attributable to Class A common shareholders, if the effect would have been dilutive, would have been $9,114 and $20,459 for the three and six months ended June 30, 2018, respectively, and $2,728 and $14,118 for the three and six months ended June 30, 2017, respectively. In computing this adjustment, the Company assumes that all vested Class A LP Units and all Class E LP Units are converted into Class A Shares, that all earnings attributable to those shares are attributed to Evercore Inc. and, that the Company is subject to the statutory tax rates of a C-Corporation under a conventional corporate tax structure in the U.S. at prevailing corporate tax rates. The Company does not anticipate that the Class A and E LP Units will result in a dilutive computation in future periods.

(c)

The Company previously had outstanding Class G and H limited partnership interests of Evercore LP ("Class G and H LP Interests") which were contingently exchangeable into Class E LP Units, and ultimately Class A Shares, and has outstanding Class I-P units of Evercore LP ("Class I-P Units") which are contingently exchangeable into Class I limited partnership units of Evercore LP ("Class I LP Units"), and ultimately Class A Shares, and outstanding Class K-P units of Evercore LP ("Class K-P Units") which are contingently exchangeable into Class K limited partnership units of Evercore LP ("Class K LP Units"), and ultimately Class A Shares, as they are subject to certain performance thresholds being achieved. In July 2017, the Company exchanged all of the outstanding Class H LP Interests for a number of Class J LP Units. As of December 31, 2017, all of the Class G LP Interests either converted into Class E LP Units or were forfeited pursuant to their performance terms. See Note 15 for further discussion. For the purposes of calculating diluted net income per share attributable to Evercore Inc. common shareholders, the Company's Class G and H LP Interests and Class I-P and Class K-P Units are included in diluted weighted average Class A Shares outstanding as of the beginning of the period in which all necessary performance conditions have been satisfied. If all necessary performance conditions have not been satisfied by the end of the period, the number of shares that are included in diluted weighted average Class A Shares outstanding is based on the number of shares that would be issuable if the end of the reporting period were the end of the performance period. The Interests/Units that were assumed to be converted to an equal number of Class A Shares for purposes of computing diluted net income per share attributable to Evercore Inc. common shareholders were 400 for the three and six months ended June 30, 2018 and 2,539 and 2,557 for the three and six months ended June 30, 2017, respectively.

The shares of Class B common stock have no right to receive dividends or a distribution on liquidation or winding up of the Company. The shares of Class B common stock do not share in the earnings of the Company and no earnings are allocable to such class. Accordingly, basic and diluted net income per share of Class B common stock have not been presented.

Share-Based and Other Deferred Compensation	6 Months Ended
Share-Based and Other Deferred Compensation	Jun. 30, 2018
Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
Share-Based and Other Deferred Compensation	Share-Based and Other Deferred Compensation LP Units Equities business - In conjunction with the acquisition of the operating businesses of International Strategy & Investment ("ISI") in 2014, the Company issued Evercore LP units and interests which have been treated as compensation, including 710 vested Class E LP Units and an allocation of the value, attributed to post-combination service, of 710 Class E LP Units that vested ratably on October 31, 2015, 2016 and 2017 and became exchangeable into Class A Shares upon vesting, subject to certain liquidated damages and continued employment provisions. Compensation expense related to Class E LP Units was $5,682 and $10,438 for the three and six months ended June 30, 2017, respectively. The Class E LP Units were fully expensed at December 31, 2017. The Company also issued 538 vested and 540 unvested Class G LP Interests, which vested ratably and became exchangeable into Class A Shares of the Company in February 2016, 2017 and 2018 if certain earnings before interest and taxes, excluding underwriting, ("Management Basis EBIT") margin thresholds within a range of 12% to 16%, were achieved for the calendar year preceding the date the interests become exchangeable. In the event of death, disability or termination of employment without cause, unvested Class G LP Interests could be canceled or vest based on determination of expected performance, based on a decision by Management. As of December 31, 2017, all of the Class G LP Interests either converted into Class E LP Units or were forfeited pursuant to their performance terms. In addition, in conjunction with the acquisition of ISI, the Company also issued 2,044 vested and 2,051 unvested Class H LP Interests, which would have vested ratably on February 15, 2018, 2019 and 2020. Subject to continued employment, the Company's vested Class H LP Interests would have become exchangeable in February 2018, 2019 and 2020, if certain average Management Basis EBIT and Management Basis EBIT margin thresholds, within ranges of $8,000 to $48,000 and 7% to 17%, respectively, were achieved for the three calendar years preceding the date the interests become exchangeable. In the event of death, disability or termination of employment without cause, unvested Class H LP Interests could be canceled or vest based on determination of expected performance, based on a decision by Management. In July 2017, the Company exchanged all of the outstanding 4,148 Class H LP Interests for 1,012 vested (963 of which are subject to certain liquidated damages and continued employment provisions) and 938 unvested Class J LP Units. These units convert into an equal amount of Class E LP Units, and become exchangeable into Class A Shares of the Company, ratably on February 15, 2018, 2019 and 2020. These Class J LP Units have the same vesting and delivery schedule, acceleration and forfeiture triggers, and distribution rights as the Class H LP Interests. In connection with this exchange, one share of Class B common stock has been issued to each holder of Class J LP Units, which entitles each holder to one vote on all matters submitted generally to holders of Class A and Class B common stock for each Class E LP Unit and Class J LP Unit held. As the number of Class J LP Units exchanged was within the number of Class H LP Interests that the Company determined were probable of being exchanged on the date of modification, the Company is expensing the previously unrecognized grant date fair value of the Class H LP Interests ratably over the remaining vesting period of the Class J LP Units. Compensation expense related to the Class J LP Units was $3,700 and $7,572 for the three and six months ended June 30, 2018, respectively. Based on Evercore ISI's results for the first six months of 2017, as well as the Company's revised outlook for the Evercore ISI business, including strategic decisions to increase the compensation ratio for this business, the Company determined that the achievement of the remaining performance thresholds for certain of the Class G LP Interests was no longer probable at March 31, 2017 or June 30, 2017. Prior to the exchange into Class J LP Units in 2017, the Company had determined that the achievement of the remaining performance thresholds for certain of the Class H LP Interests was probable at June 30, 2017, but at a lower assumed performance level than previously determined. These determinations resulted in previously recognized expense of $26,224 for certain of the Class G and H LP Interests being reversed during the first quarter of 2017. The determination assumed a Management Basis EBIT margin of 11.7% and an annual Management Basis EBIT of $26,904 being achieved in 2017 and a Management Basis EBIT margin of 14.0% and an annual Management Basis EBIT of $34,357 being achieved in 2018 and 2019 for Evercore ISI, which would have resulted in 2,005 Class H LP Interests vesting and becoming exchangeable into Class E LP Units. Accordingly, $11,324 of expense was recorded and $14,900 of expense was reversed for the three and six months ended June 30, 2017, respectively, for the Class G and H LP Interests. During the first quarter of 2017, the Company amended the terms of 19 Class E LP Units, 14 Class G LP Interests and 162 Class H LP Interests for an exiting employee. The amendment resulted in expense, included within compensation expense related to the Class E LP Units and Class G and H LP Interests above, of $6,554 and $3,532 for the three and six months ended June 30, 2017, respectively, reflecting the reversal of all previous expense related to these awards and the subsequent amortization of the awards at the amended grant date fair value of $14,891. These awards were amortized ratably through June 30, 2017. Other Performance-based Awards - In November 2016, the Company issued 400 Class I-P Units in conjunction with the appointment of the Executive Chairman. These Class I-P Units convert into a specified number of Class I LP Units, which are exchangeable on a one-for-one basis to Class A Shares, contingent on the achievement of certain market and service conditions, subject to vesting upon specified termination events (including retirement, upon satisfying certain eligibility criteria, on or following January 15, 2022, subject to a one year prior written notice requirement) or a change in control. These Class I-P Units are segregated into two groups of 200 units each, with share price threshold vesting conditions which are required to exceed a certain level for 20 consecutive trading days (which were met as of March 31, 2017). The Company determined the fair value of the award to be $24,412 and is expensing the award ratably over the implied service period, which ends on March 1, 2022. As the award contains market-based conditions, the entire expense will be recognized if the award does not vest for any reason other than the service conditions. Compensation expense related to this award was $1,152 and $2,291 for the three and six months ended June 30, 2018 and 2017, respectively. In November 2017, the Company issued 64 Class K-P Units to an employee of the Company. These Class K-P Units convert into a specified number of Class K LP Units, which are exchangeable on a one-for-one basis to Class A Shares, contingent upon the achievement of certain defined benchmark results and continued service through December 31, 2021. An additional 16 Class K-P Units may be issued contingent upon the achievement of certain defined benchmark results and continued service through December 31, 2021. The Company determined the fair value of the award probable to vest to be $5,000 and will record expense for these units over the service period. Compensation expense related to this award was $299 and $595 for the three and six months ended June 30, 2018, respectively. Stock Incentive Plan During 2016, the Company's stockholders approved the Amended and Restated 2016 Evercore Inc. Stock Incentive Plan (the "2016 Plan"). The 2016 Plan, among other things, authorizes an additional 10,000 shares of the Company's Class A Shares. The 2016 Plan permits the Company to grant to key employees, directors and consultants incentive stock options, non-qualified stock options, stock appreciation rights, restricted stock, RSUs and other awards based on the Company's Class A Shares. The Company intends to use newly-issued Class A Shares to satisfy any awards under the 2016 Plan and its predecessor plan. Class A Shares underlying any award granted under the 2016 Plan that expire, terminate or are canceled or satisfied for any reason without being settled in stock again become available for awards under the plans. The total shares available to be granted in the future under the 2016 Plan was 5,399 and 7,423 as of June 30, 2018 and 2017, respectively. The Company also grants, at its discretion, dividend equivalents, in the form of unvested RSU awards, or deferred cash dividends, concurrently with the payment of dividends to the holders of Class A Shares, on all unvested RSU grants awarded in conjunction with annual bonuses, as well as new hire awards. The dividend equivalents have the same vesting and delivery terms as the underlying RSU award. The Company estimates forfeitures in the aggregate compensation cost to be amortized over the requisite service period of its awards. The Company periodically monitors its estimated forfeiture rate and adjusts its assumptions to the actual occurrence of forfeited awards. A change in estimated forfeitures is recognized through a cumulative adjustment in the period of the change. Equity Grants During the six months ended June 30, 2018, pursuant to the 2016 Plan, the Company granted employees 1,885 RSUs that are Service-based Awards. Service-based Awards granted during the six months ended June 30, 2018 had grant date fair values of $86.23 to $109.85 per share. During the six months ended June 30, 2018, 2,417 Service-based Awards vested and 37 Service-based Awards were forfeited. Compensation expense related to Service-based Awards, including RSUs granted to the Executive Chairman in November 2016, was $46,375 and $89,106 for the three and six months ended June 30, 2018, respectively, and $41,825 and $82,869 for the three and six months ended June 30, 2017, respectively. Deferred Cash The Company's deferred cash compensation program provides participants the ability to elect to receive a portion of their deferred compensation in cash, which is indexed to a notional investment portfolio and vests ratably over four years and requires payment upon vesting. The Company granted $82,592, $3,750 and $41,147 of deferred cash awards pursuant to the deferred cash compensation program during the first quarter of 2018 and the years ended December 31, 2017 and 2016, respectively. In November 2016, the Company granted a restricted cash award in conjunction with the appointment of the Executive Chairman with a target payment amount of $35,000, of which $11,000 is scheduled to vest on March 1, 2019 and $6,000 is scheduled to vest on each of the first four anniversaries of March 1, 2019, provided that the Executive Chairman continues to remain employed through each such vesting date, subject to vesting upon specified termination events (including retirement, upon satisfying certain eligibility criteria, on or following May 1, 2019, subject to a six month prior written notice requirement) or a change in control. The Company has the discretion to increase (by an amount up to $35,000) or decrease (by an amount up to $8,750) the total amount payable under this award. In 2017, the Company granted deferred cash awards of $29,500 to certain employees. These awards vest in five equal installments over the period ending June 30, 2022, subject to continued employment. The Company records expense for these awards ratably over the vesting period. Compensation expense related to deferred cash awards was $15,750 and $28,341 for the three and six months ended June 30, 2018, respectively, and $5,423 and $9,820 for the three and six months ended June 30, 2017, respectively. Long-term Incentive Plan The Company's Long-term Incentive Plan provides for incentive compensation awards to Advisory Senior Managing Directors, excluding executive officers of the Company, who exceed defined benchmark results over four-year performance periods beginning January 1, 2013 and January 1, 2017. These awards, which aggregate $56,222 of liabilities on the Unaudited Condensed Consolidated Statement of Financial Condition as of June 30, 2018, are due to be paid, in cash or Class A Shares, at the Company's discretion, in three equal installments in the first quarter of 2017, 2018 and 2019 (for the performance period beginning on January 1, 2013) and in the first quarter of 2021, 2022 and 2023 (for the performance period beginning on January 1, 2017), subject to employment at the time of payment. These awards are subject to retirement eligibility requirements. The Company periodically assesses the probability of the benchmarks being achieved and expenses the probable payout over the requisite service period of the award. The compensation expense related to these awards was $6,948 and $14,075 for the three and six months ended June 30, 2018, respectively, and $6,700 and $12,558 for the three and six months ended June 30, 2017, respectively. In conjunction with this plan, the Company distributed cash payments of $4,532 and $19,401 for the six months ended June 30, 2018 and 2017, respectively. Employee Loans Receivable Periodically, the Company provides new and existing employees with cash payments in the form of loans and/or other cash awards which are subject to ratable vesting terms with service requirements ranging from one to five years and in certain circumstances, subject to the achievement of performance requirements. Generally, the terms of these awards include a requirement of either full or partial repayment of these awards based on the terms of their employment agreements with the Company. In circumstances where the employee meets the Company's minimum credit standards, the Company amortizes these awards to compensation expense over the relevant service period which is generally the period they are subject to forfeiture. Compensation expense related to these awards was $4,787 and $8,109 for the three and six months ended June 30, 2018, respectively, and $4,857 and $9,030 for the three and six months ended June 30, 2017, respectively. The remaining unamortized amount of these awards was $37,282 as of June 30, 2018. Separation and Transition Benefits The Company granted separation benefits to certain employees, resulting in expense included in Employee Compensation and Benefits of approximately $3,066 and $6,484 for the three and six months ended June 30, 2018, respectively, and $2,859 and $3,468 for the three and six months ended June 30, 2017, respectively. In conjunction with these arrangements, the Company distributed cash payments of $2,997 and $5,873 for the three and six months ended June 30, 2018, respectively, and $2,235 and $2,346 for the three and six months ended June 30, 2017, respectively.

Operating Leases – The Company leases office space under non-cancelable lease agreements, which expire on various dates through 2025. The Company reflects lease expense over the lease terms on a straight-line basis. Occupancy lease agreements, in addition to base rentals, generally are subject to escalation provisions based on certain costs incurred by the landlord. Occupancy and Equipment Rental on the Unaudited Condensed Consolidated Statements of Operations includes occupancy rental expense relating to operating leases of $10,454 and $20,571 for the three and six months ended June 30, 2018, respectively, and $10,371 and $19,888 for the three and six months ended June 30, 2017, respectively.

On July 1, 2018, the Company entered into a new lease agreement for office space at its headquarters at 55 East 52nd St., New York, New York. Under the terms of the agreement, the Company committed to extend the lease term for its current space and add space on up to seven additional floors, three of which commence as of the lease’s effective date. The Company anticipates it will take possession of the remainder of these floors over the next five years. When all floors have commenced, the Company will have approximately 350,000 square feet of space at this location. The lease term for all current and prospective space will end on June 30, 2034. The Company anticipates that the approximate aggregate additional minimum future payments under this arrangement, net of rent abatement and certain other rent credits, will be as follows:



2018	$	31
2019	629
2020	6,240
2021	11,671
2022	16,641
Thereafter	402,976
Total	$	438,188

Private Equity – As of June 30, 2018, the Company had unfunded commitments for capital contributions of $3,255 to private equity funds. These commitments will be funded as required through the end of each private equity fund's investment period, subject to certain conditions. Such commitments are satisfied in cash and are generally required to be made as investment opportunities are consummated by the private equity funds.

Lines of Credit – On June 24, 2016, Evercore Partners Services East L.L.C. ("East") entered into a loan agreement with PNC Bank, National Association ("PNC") for a revolving credit facility in an aggregate principal amount of up to $30,000, to be used for working capital and other corporate activities. This facility is secured by East's accounts receivable and the proceeds therefrom, as well as certain assets of EGL, including certain of EGL's accounts receivable. In addition, the agreement contains certain reporting covenants as well as certain debt covenants that prohibit East and the Company from incurring other indebtedness subject to specified exceptions. The Company was in compliance with these covenants as of June 30, 2018. Drawings under this facility bear interest at the prime rate. On January 2, 2018, East drew down $30,000 on this facility, which was repaid on March 2, 2018. The facility was renewed on June 21, 2018, and the maturity date was extended to June 21, 2019.

ECB maintains a line of credit with BBVA Bancomer to fund its trading activities on an intra-day and overnight basis. The facility has a maximum aggregate principal amount of approximately $10,037 and is secured by trading securities. No interest is charged on the intra-day facility. The overnight facility is charged the Inter-Bank Balance Interest Rate plus 10 basis points. There have been no significant draw downs on ECB's line of credit since August 10, 2006. The line of credit is renewable annually.

Other Commitments – In addition, the Company enters into commitments to pay contingent consideration related to certain of its acquisitions. At June 30, 2018, the Company had a remaining commitment for contingent consideration related to its acquisition of Kuna & Co. KG in 2015.

The Company also had a commitment at June 30, 2018 for contingent consideration related to an arrangement with the former employer of certain RECA employees. See Note 5 for further information.

Restricted Cash – The following table provides a reconciliation of cash, cash equivalents and restricted cash reported within the statements of financial position that sum to the total of amounts shown in the Unaudited Condensed Consolidated Statements of Cash Flows:



	June 30,
	2018		2017
Cash and Cash Equivalents	$	403,929	$	410,212
Restricted Cash included in Other Assets	11,072		17,752
Total Cash, Cash Equivalents and Restricted Cash shown in the Statement of Cash Flows	$	415,001	$	427,964

Restricted Cash included in Other Assets on the Unaudited Condensed Consolidated Statements of Financial Condition primarily represents letters of credit which are secured by cash as collateral for the lease of office space and security deposits for certain equipment. The restrictions will lapse when the leases end.

Foreign Exchange – The Company entered into foreign currency exchange forward contracts to sell 2.2 billion Japanese yen for $20,136 during the second quarter of 2018 to fix the exchange rate for Japanese yen denominated accounts receivable. These contracts settle during the third quarter of 2018. The contracts are recorded at their fair value of $115 as of June 30, 2018, and are included in Other Current Assets on the Unaudited Condensed Consolidated Statements of Financial Condition.

Contingencies

In the normal course of business, from time to time the Company and its affiliates are involved in judicial or regulatory proceedings, arbitration or mediation concerning matters arising in connection with the conduct of its businesses, including contractual and employment matters. In addition, Mexican, United Kingdom, Hong Kong, Singapore, Canadian, Dubai and United States government agencies and self-regulatory organizations, as well as state securities commissions in the United States, conduct periodic examinations and initiate administrative proceedings regarding the Company's business, including, among other matters, accounting and operational matters, that can result in censure, fine, the issuance of cease-and-desist orders or the suspension or expulsion of a broker-dealer, investment advisor, or its directors, officers or employees. In view of the inherent difficulty of determining whether any loss in connection with such matters is probable and whether the amount of such loss can be reasonably estimated, particularly in cases where claimants seek substantial or indeterminate damages or where investigations and proceedings are in the early stages, the Company cannot estimate the amount of such loss or range of loss, if any, related to such matters, how or if such matters will be resolved, when they will ultimately be resolved, or what the eventual settlement, fine, penalty or other relief, if any, might be. Subject to the foregoing, the Company believes, based on current knowledge and after consultation with counsel, that it is not currently party to any material pending proceedings, individually or in the aggregate, the resolution of which would have a material effect on the Company. Provisions for losses are established in accordance with ASC 450, "Contingencies" when warranted. Once established, such provisions are adjusted when there is more information available or when an event occurs requiring a change.

Income Taxes	6 Months Ended
Income Taxes	Jun. 30, 2018
Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The Company's Provision for Income Taxes was $25,541 and $30,479 for the three and six months ended June 30, 2018, respectively, and $22,459 and $40,751 for the three and six months ended June 30, 2017, respectively. The effective tax rate was 24% and 14% for the three and six months ended June 30, 2018, respectively, and 46% and 25% for the three and six months ended June 30, 2017, respectively. In conjunction with the enactment of the Tax Cuts and Jobs Act on December 22, 2017, which reduced income tax rates in the U.S. in 2018 and future years, the Company's effective tax rate for the three and six months ended June 30, 2018 was reduced by 13 and 12 percentage points, respectively, before the impact of ASU 2016-09, "Improvements to Employee Share-Based Payment Accounting" ("ASU 2016-09"). The effective tax rate for the three and six months ended June 30, 2018 also reflects the application of ASU 2016-09, which was adopted effective January 1, 2017. ASU 2016-09 requires that the tax deduction associated with the appreciation in the Company's share price upon vesting of employee share-based awards above the original grant price be reflected in income tax expense. The application of 2016-09 resulted in excess tax benefits from the delivery of Class A common stock under share-based payment arrangements of $22,222 and $23,172 being recognized in the Company's Provision for Income Taxes for the six months ended June 30, 2018 and 2017, respectively, and resulted in a reduction in the effective tax rate of 10 and 14 percentage points for the six months ended June 30, 2018 and 2017, respectively. The effective tax rate for 2018 and 2017 also reflects the effect of certain nondeductible expenses, including expenses related to Class E, J, I-P and K-P LP Units and Class G and H LP Interests, as well as the noncontrolling interest associated with LP Units and other adjustments. On December 22, 2017, the SEC issued SAB 118 to address the application of U.S. GAAP in situations when a registrant does not have the necessary information available or computed analysis in reasonable detail to complete the accounting for certain income tax effects of the Tax Cuts and Jobs Act. The Company recognized a provisional tax impact related to the re-measurement of net deferred tax assets, the write down of other comprehensive income related to certain foreign subsidiaries, the valuation allowance and effects of the mandatory deemed repatriation tax on undistributed earnings of foreign subsidiaries within its consolidated financial statements for the year ended December 31, 2017. The Company's estimated tax charge as a result of the Tax Cuts and Jobs Act could be subject to adjustments as the Company continues its analysis, which may be impacted by changes in interpretations and assumptions the Company has made in conjunction with the release of additional regulatory guidance that may be issued. There were no changes to the provisional amounts recognized in 2017; the Company expects to record any adjustments to the estimated tax impact associated with the Tax Cuts and Jobs Act in the period in which the items are recognized. Additionally, the Company expects to recognize the income tax effects associated with the new global intangible low-taxed income ("GILTI") provisions in the period incurred. For the three and six months ended June 30, 2018, no additional income tax expense associated with the GILTI provisions has been reported and it is not expected to be material to the Company’s effective tax rate for the year. The Company reported an increase in deferred tax assets of $130 associated with changes in Unrealized Gain (Loss) on Marketable Securities and an increase of $1,108 associated with changes in Foreign Currency Translation Adjustment Gain (Loss), in Accumulated Other Comprehensive Income (Loss) for the six months ended June 30, 2018. The Company reported a decrease in deferred tax assets of $205 associated with changes in Unrealized Gain (Loss) on Marketable Securities and a decrease of $629 associated with changes in Foreign Currency Translation Adjustment Gain (Loss), in Accumulated Other Comprehensive Income (Loss) for the six months ended June 30, 2017. As of June 30, 2018, the Company had no unrecognized tax benefits. The Company classifies interest relating to tax matters and tax penalties as a component of income tax expense in its Unaudited Condensed Consolidated Statements of Operations.

Significant Accounting Policies (Policies)	6 Months Ended
Significant Accounting Policies (Policies)	Jun. 30, 2018
Accounting Policies [Abstract]
Basis of Presentation, Policy	Basis of Presentation – The accompanying unaudited condensed consolidated financial statements of the Company have been prepared in accordance with the instructions to Form 10-Q. As permitted by the rules and regulations of the United States Securities and Exchange Commission, the unaudited condensed consolidated financial statements contain certain condensed financial information and exclude certain footnote disclosures normally included in audited consolidated financial statements prepared in accordance with accounting principles generally accepted in the United States of America ("U.S. GAAP"). The accompanying condensed consolidated financial statements are unaudited and are prepared in accordance with U.S. GAAP. In the opinion of the Company's management, the accompanying unaudited condensed consolidated financial statements contain all adjustments, including normal recurring accruals, necessary to fairly present the accompanying unaudited condensed consolidated financial statements. These unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements included in the Company's annual report on Form 10-K for the year ended December 31, 2017. The December 31, 2017 Unaudited Condensed Consolidated Statement of Financial Condition data was derived from audited consolidated financial statements, but does not include all disclosures required by U.S. GAAP. Operating results for the interim periods are not necessarily indicative of the results that may be expected for the fiscal year ending December 31, 2018. The accompanying unaudited condensed consolidated financial statements of the Company are comprised of the consolidation of Evercore LP and Evercore LP's wholly-owned and majority-owned direct and indirect subsidiaries, including Evercore Group L.L.C. ("EGL"), a registered broker-dealer in the U.S. The Company's policy is to consolidate all subsidiaries in which it has a controlling financial interest, as well as any variable interest entities ("VIEs") where the Company is deemed to be the primary beneficiary, when it has the power to make the decisions that most significantly affect the economic performance of the VIE and has the obligation to absorb significant losses or the right to receive benefits that could potentially be significant to the VIE. The Company reviews factors, including the rights of the equity holders and obligations of equity holders to absorb losses or receive expected residual returns, to determine if the investment is a VIE. In evaluating whether the Company is the primary beneficiary, the Company evaluates its economic interests in the entity held either directly or indirectly by the Company. The consolidation analysis is generally performed qualitatively. This analysis, which requires judgment, is performed at each reporting date.

Revenue Recognition, Policy [Policy Text Block]	The Company adopted ASU No. 2014-09, "Revenue from Contracts with Customers" ("ASU 2014-09") on January 1, 2018 using the modified retrospective method of transition. The Company did not have a cumulative-effect adjustment as of the date of adoption. Following the adoption of ASU 2014-09, the Company’s accounting policies are as follows: ASU 2014-09 provides a five step model to revenue recognition: Step 1: Identify the contract(s) with a customer Step 2: Identify the performance obligations in the contract Step 3: Determine the transaction price Step 4: Allocate the transaction price to the performance obligations in the contract Step 5: Recognize revenue when (or as) the entity satisfies a performance obligation The Company applies this model to its Investment Banking and Asset Management revenue streams. Investment Banking Revenue - The Company earns investment banking fees from clients for providing advisory services on strategic matters, including mergers, acquisitions, divestitures, leveraged buyouts, restructurings, activism and defense and similar corporate finance matters. The Company's Investment Banking services also include services related to securities underwriting, private placement services and commissions for agency-based equity trading services and equity research. Revenue is recognized as the Company satisfies performance obligations, upon transfer of control of promised services to customers in an amount that reflects the consideration the Company expects to receive in exchange for these services. The Company’s contracts with customers may include promises to transfer multiple services to a customer. Determining whether services are considered distinct performance obligations that should be accounted for separately versus together may require significant judgment. For performance obligations satisfied over time, determining a measure of progress requires the Company to make significant judgments that affect the timing of revenue recognized. For certain advisory services, the Company has concluded that performance obligations are satisfied over time. This is based on the premise that the Company transfers control of services and the client simultaneously receives benefits from these services over the course of an engagement. For performance obligations satisfied at a point in time, determining when control transfers requires the Company to make significant judgments that affect the timing of when revenue is recognized. The Company records Investment Banking Revenue on the Unaudited Condensed Consolidated Statements of Operations for the following: Advisory Fees - In general, advisory fees are paid at the time the Company signs an engagement letter, during the course of the engagement or when an engagement is completed. In some circumstances, and as a function of the terms of an engagement letter, the Company may receive fixed retainer fees for financial advisory services concurrent with, or soon after, the execution of the engagement letter or over the course of the engagement, where the engagement letter will specify a future service period associated with those fees. The Company may also receive announcement fees upon announcement of a transaction in addition to success fees upon closing of a transaction or another defined outcome, both of which represent variable consideration. This variable consideration will be included in the transaction price, as defined, to the extent that it is probable that a significant reversal of revenue will not occur. With respect to retainer, announcement and success fees, there are no distinct performance obligations aside from advisory activities, which are generally focused on achieving a milestone (typically, the announcement and/or the closing of a transaction). These advisory services are provided over time throughout the contract period. The Company will recognize revenue when distinct services are performed and when it is probable that a reversal of revenue will not occur, which is generally upon the announcement or closing of a transaction. In circumstances in which retainer fees are received in advance of services, these fees are initially recorded as deferred revenue (a contract liability), which is recorded in Other Current Liabilities on the Unaudited Condensed Consolidated Statements of Financial Condition, and subsequently recognized as advisory fee revenue in Advisory Fees on the Unaudited Condensed Consolidated Statements of Operations during the applicable time period within which the service is rendered. Announcement fees for advisory services are recognized upon announcement (the point at which it is determined that the reversal of revenue is not probable) and all other requirements for revenue recognition are satisfied. A portion of the announcement fee may be deferred based on the services remaining to be completed, if any. Success fees for advisory services, such as merger and acquisition advice, are recognized when it is determined that the reversal of revenue is not probable and all other requirements for revenue recognition are satisfied, which is generally at closing of the transaction. With respect to fairness or valuation opinions, fees are fixed and there is a distinct performance obligation, since the opinion is rendered separate from any other advisory activities. Revenues related to fairness or valuation opinions are recognized at the point in time when the opinion has been rendered and delivered to the client. In the event the Company was to receive an opinion or success fee in advance of the completion conditions noted above, such fee would initially be recorded as deferred revenue (a contract liability) in Other Current Liabilities on the Unaudited Condensed Consolidated Statements of Financial Condition and subsequently recognized as advisory fee revenue in Advisory Fees on the Unaudited Condensed Consolidated Statements of Operations when the conditions of completion have been satisfied. Placement fee revenues are attributable to capital raising on both corporations and financial sponsors. The Company recognizes placement fees in accordance with the terms of the engagement letter, which are generally contingent on the achievement of a capital commitment by an investor, at the time of the client's acceptance of capital or capital commitments. Underwriting Fees - Underwriting fees are attributable to public and private offerings of equity and debt securities and are recognized at the point in time when the offering has been deemed to be completed by the lead manager of the underwriting group. When the offering is completed, the performance obligation has been satisfied and the Company recognizes the applicable management fee, selling concession and underwriting fee. Estimated offering expenses are presented gross in the Unaudited Condensed Consolidated Statements of Operations. Commissions and Related Fees - Commissions and Related Fees include commissions received from customers for the execution of agency-based brokerage transactions in listed and over-the-counter equities. The execution of each trade order represents a distinct performance obligation and the transaction price at the point in time of trade order execution is fixed. Trade execution is satisfied at the point in time that the customer has control of the asset and as such, fees are recorded on a trade date basis or, in the case of payments under commission sharing arrangements, when earned. The Company also earns subscription fees for the sales of research. The delivery of research under subscription arrangements represents a distinct performance obligation that is satisfied over time. The fees are fixed and are recognized over the period in which the performance obligation is satisfied. Cash received before the subscription period ends is initially recorded as deferred revenue (a contract liability) in Other Current Liabilities on the Unaudited Condensed Consolidated Statements of Financial Condition, and is recognized in Commissions and Related Fees on the Unaudited Condensed Consolidated Statements of Operations ratably over the period in which the related services are rendered. Taxes collected from customers and remitted to governmental authorities are presented on a net basis on the Consolidated Statements of Operations. Asset Management and Administration Fees - The Company's Investment Management business generates revenues from the management of client assets and through interests in private equity funds which are not managed by the Company. The Company’s contracts with customers may include promises to transfer multiple services to a customer. Determining whether services are considered distinct performance obligations that should be accounted for separately versus together may require significant judgment. For performance obligations satisfied over time, determining a measure of progress requires the Company to make significant judgments that affect the timing of revenue recognized. Asset management fees for third-party clients are generally based on the value of the assets under management and any performance fees that may be negotiated with the client. The management of asset portfolios represents a distinct performance obligation that is satisfied over time. These fees are generally recognized over the period that the related services are provided and in which the performance obligation is satisfied, based upon the beginning, ending or average value of the assets for the relevant period. Fees paid in advance of services rendered are initially recorded as deferred revenue (a contract liability), which is recorded in Other Current Liabilities on the Unaudited Condensed Consolidated Statements of Financial Condition, and are recognized in Asset Management and Administration Fees on the Unaudited Condensed Consolidated Statements of Operations ratably over the period in which the related service is rendered. Generally, to the extent performance fee arrangements have been negotiated, these fees are earned when the likelihood of clawback is mathematically improbable. Fees generated for serving as an independent fiduciary and/or trustee are either based on a flat fee, are pre-negotiated with the client or are based on the value of assets under administration. The management of assets under administration represents a distinct performance obligation that is satisfied over time. For ongoing engagements, fees are billed quarterly either in advance or in arrears. Fees paid in advance of services rendered and satisfaction of the performance obligation are initially recorded as deferred revenue (a contract liability) in Other Current Liabilities on the Unaudited Condensed Consolidated Statements of Financial Condition, and are recognized in Asset Management and Administration Fees on the Unaudited Condensed Consolidated Statements of Operations ratably over the period in which the related services are rendered and the performance obligation is satisfied. The Company records performance fee revenue from the private equity funds when the returns on the private equity funds' investments exceed certain threshold minimums. These performance fees, or carried interest, are computed in accordance with the underlying private equity funds' partnership agreements and are based on investment performance over the life of each investment partnership. The Company records performance fees upon the earlier of the termination of the investment fund or when the likelihood of clawback is mathematically improbable.
Receivables, Policy [Policy Text Block]	Accounts Receivable and Contract Assets - Accounts Receivable consists primarily of investment banking fees and expense reimbursements charged to the Company's clients. The Company records Accounts Receivable, net of any allowance for doubtful accounts, when relevant revenue recognition criteria has been achieved and payment is conditioned on the passage of time. The Company maintains an allowance for doubtful accounts to provide coverage for estimated losses from its client receivables. The Company determines the adequacy of the allowance by estimating the probability of loss based on the Company's analysis of the client's creditworthiness and specifically reserves against exposure where the Company determines the receivables are impaired, which may include situations where a fee is in dispute or litigation has commenced. The Investment Banking and Investment Management receivables collection periods generally are within 90 days of invoice, with the exception of placement fees, which are generally collected within 180 days of invoice, and fees related to private funds capital raising, which are collected in a period exceeding one year. The collection period for restructuring transactions and private equity fee receivables may exceed 90 days. Receivables that are collected in a period exceeding one year are reflected in Other Assets on the Unaudited Condensed Consolidated Statement of Financial Condition. The Company records contract assets within Other Current Assets on the Unaudited Condensed Consolidated Statement of Financial Condition when payment is due from a client conditioned on future performance or the occurrence of other events. The Company also recognizes a contract asset for the incremental costs of obtaining a contract with a customer if the benefit of those costs is expected to be longer than one year. The Company applies a practical expedient to expense costs to obtain a contract as incurred when the amortization period is one year or less.
