Summary of Significant Accounting Policies	Dec. 31, 2013
Accounting Policies [Abstract]	'
Summary of Significant Accounting Policies	'
	Basis of Financial Information
	These consolidated financial statements are prepared in conformity with accounting principles generally accepted in the United States (U.S. GAAP), which require management to make estimates and assumptions regarding future events that affect the amounts reported in our financial statements and these footnotes, including investment valuations, compensation accruals and other matters. Management believes that the estimates used in preparing its consolidated financial statements are reasonable and prudent. Actual results could differ materially from those estimates. Certain reclassifications have been made to prior year information to conform to current year presentation.
	The consolidated financial statements of the Company include all consolidated accounts of Greenhill & Co., Inc. and all other entities in which the Company has a controlling interest after eliminations of all significant inter-company accounts and transactions. In accordance with the accounting pronouncements related to consolidation of variable interest entities, the Company consolidates the general partners of certain merchant banking funds in which it has a majority of the economic interest and control. The general partners account for their investments in these merchant banking funds under the equity method of accounting. As such, the general partners record their proportionate shares of income (loss) from the underlying merchant banking funds. As these merchant banking funds follow investment company accounting, and generally record all their assets and liabilities at fair value, the general partners’ investment in these merchant banking funds represents an estimation of fair value. The Company does not consolidate the merchant banking funds since the Company, through its general partner and limited partner interests, does not have a majority of the economic interest in such funds and the limited partners have certain rights to remove the general partner by a simple majority vote of unaffiliated third-party investors.
	Revenue Recognition
	Advisory Revenues

	It is the Company's accounting policy to recognize revenue when (i) there is persuasive evidence of an arrangement with a client, (ii) the agreed-upon services have been completed and delivered to the client or the transaction or events noted in the engagement letter are determined to be substantially complete, (iii) fees are fixed and determinable, and (iv) collection is reasonably assured.

	The Company recognizes advisory fee revenues for mergers and acquisitions or financing advisory and restructuring engagements when the services related to the underlying transactions are completed in accordance with the terms of the engagement letter and all other requirements for revenue recognition are satisfied.

	The Company recognizes private equity and real estate capital advisory fees at the time of the client's acceptance of capital or capital commitments to a fund in accordance with the terms of the engagement letter. Generally, fee revenue is determined based upon a fixed percentage of capital committed to the fund. For multiple closings, revenue is recognized at each interim closing based on the amount of capital committed at each closing at the fixed fee percentage. At the final closing, revenue is recognized at the fixed percentage for the amount of capital committed since the last interim closing.

	While the majority of the Company's fee revenue is earned at the conclusion of a transaction or closing of a fund, on-going retainer fees, substantially all of which relate to non-success based strategic advisory and financing advisory and restructuring assignments, are also earned and recognized as advisory fee revenue over the period in which the related service is rendered.

	The Company’s clients reimburse certain expenses incurred by the Company in the conduct of advisory engagements. Expenses are reported net of such client reimbursements. Client reimbursements totaled $6.5 million, $7.4 million and $6.5 million for the years ended December 31, 2013, 2012, and 2011, respectively.
	Investment Revenues
	Investment revenues consist of (i) gains (or losses) on the Company's investments in certain merchant banking funds, Iridium and other investments, and (ii) interest income.
	The Company recognizes revenue on its investments in merchant banking funds based on its allocable share of realized and unrealized gains (or losses) reported by such funds. The Company recognizes revenue on its other investments, including Iridium, which considers the Company's influence or control of the investee, based on gains and losses on investment positions held, which arise from sales or changes in the fair value of investments. The amount of gains or losses are not predictable and can cause periodic fluctuations in net income and therefore subject the Company to market and credit risk.
	Cash and Cash Equivalents
	The Company’s cash and cash equivalents consist of (i) cash held on deposit with financial institutions, (ii) cash equivalents and (iii) restricted cash. The Company maintains its cash and cash equivalents with financial institutions with high credit ratings. The Company considers all highly liquid investments with a maturity date of three months or less, when purchased, to be cash equivalents. Cash equivalents primarily consist of money market funds and overnight deposits.
	Management believes that the Company is not exposed to significant credit risk due to the financial position of the depository institutions in which those deposits are held. See "Note 3 — Cash and Cash Equivalents".
	Advisory Fees Receivables
	Receivables are stated net of an allowance for doubtful accounts. The estimate for the allowance for doubtful accounts is derived by the Company by utilizing past client transaction history and an assessment of the client’s creditworthiness. The Company did not record a bad debt expense in any of the years ended December 31, 2013, 2012 or 2011.
	Included in the advisory fees receivable balance at December 31, 2013 and 2012 were $34.0 million and $29.8 million of long term receivables related to private equity and real estate capital advisory engagements which are generally paid in installments over a period of three years. Included as a component of investment revenues on the consolidated statements of income is interest income related to capital advisory engagements of $0.8 million, $1.2 million and $0.1 million for the years ended December 31, 2013, 2012 and 2011, respectively.
	Credit risk related to advisory fees receivable is disbursed across a large number of clients located in various geographic areas. The Company controls credit risk through credit approvals and monitoring procedures but does not require collateral to support accounts receivable.
	Investments
	The Company's investments in merchant banking funds are recorded under the equity method of accounting based upon the Company's proportionate share of the estimated fair value of the underlying merchant banking fund's net assets. The value of merchant banking fund investments in privately held companies is determined by management of the fund after giving consideration to the cost of the security, the pricing of other sales of securities by the portfolio company, the price of securities of other companies comparable to the portfolio company, purchase multiples paid in other comparable third-party transactions, the original purchase price multiple, market conditions, liquidity, operating results and other qualitative and quantitative factors. Discounts may be applied to the funds' privately held investments to reflect the lack of liquidity and other transfer restrictions. Investments in publicly traded securities are valued using quoted market prices discounted for any legal or contractual restrictions on sale. Because of the inherent uncertainty of valuations as well as the discounts applied, the estimated fair values of investments in privately held companies may differ significantly from the values that would have been used had a ready market for the securities existed. The values at which the Company's investments are carried on its consolidated statements of financial condition are adjusted to estimated fair value at the end of each quarter and the volatility in general economic conditions, stock markets and commodity prices may result in significant changes in the estimated fair value of the investments from period to period.
	Goodwill
	Goodwill is the cost in excess of the fair value of identifiable net assets at acquisition date. The Company tests its goodwill for impairment at least annually. An impairment loss is triggered if the estimated fair value of an operating unit is less than estimated net book value. Such loss is calculated as the difference between the estimated fair value of goodwill and its carrying value.
	Goodwill is translated at the rate of exchange prevailing at the end of the periods presented in accordance with the accounting guidance for foreign currency translation. Any translation gain or loss is included in the foreign currency translation adjustment, which is included as a component of other comprehensive income in the consolidated statements of changes in equity.
	Restricted Stock Units
	The Company accounts for its share-based compensation payments by recording the fair value of restricted stock units granted to employees as compensation expense. The restricted stock units are generally amortized over a five-year service period following the date of grant. Compensation expense is determined based upon the fair market value of the Company’s common stock at the date of grant. As the Company expenses the awards, the restricted stock units recognized are recorded within equity. The restricted stock units are reclassified into common stock and additional paid-in capital upon vesting. The Company records as treasury stock the repurchase of stock delivered to its employees in settlement of tax liabilities incurred upon the vesting of restricted stock units. The Company records dividend equivalent payments, net of estimated forfeitures, on outstanding restricted stock units as a dividend payment and a charge to equity.
	Earnings per Share
	The Company calculates basic earnings per share (“EPS”) by dividing net income allocated to common stockholders by the sum of (i) the weighted average number of shares outstanding for the period and (ii) the weighted average number of shares deemed issuable due to the vesting of restricted stock units for accounting purposes. In addition, the contingent convertible preferred shares will also be included in the weighted average number of shares to the extent they are deemed to have met the performance targets. See "Note 9 — Equity".
	The Company calculates diluted EPS by dividing net income allocated to common stockholders by the sum of (i) basic shares per above and (ii) the dilutive effect of the common stock deliverable pursuant to restricted stock units for which future service is required. Under the treasury method, the number of shares issuable upon the vesting of restricted stock units included in the calculation of diluted EPS is the excess, if any, of the number of shares expected to be issued, less the number of shares that could be purchased by the Company with the proceeds to be received upon settlement at the average market closing price during the reporting period.
	Provision for Taxes
	The Company accounts for taxes in accordance with the accounting guidance for income taxes, which requires the recognition of tax benefits or expenses on the temporary differences between the financial reporting and tax bases of its assets and liabilities.
	The Company follows the guidance for income taxes in recognizing, measuring, presenting and disclosing in its financial statements uncertain tax positions taken or expected to be taken on its income tax returns. Income tax expense is based on pre-tax accounting income, including adjustments made for the recognition or derecognition related to uncertain tax positions. The recognition or derecognition of income tax expense related to uncertain tax positions is determined under the guidance.
	Deferred tax assets and liabilities are recognized for the future tax attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in earnings in the period of change. Management applies the “more-likely-than-not criteria” when determining tax benefits.
	Foreign Currency Translation
	Assets and liabilities denominated in foreign currencies have been translated at rates of exchange prevailing at the end of the periods presented in accordance with the accounting guidance for foreign currency translation. Income and expenses transacted in foreign currency have been translated at average monthly exchange rates during the period. Translation gains and losses are included in the foreign currency translation adjustment, which is included as a component of other comprehensive income (loss) in the consolidated statement of changes in equity. Foreign currency transaction gains and losses are included in the consolidated statements of income.
	Financial Instruments and Fair Value
	The Company accounts for financial instruments measured at fair value in accordance with accounting guidance for fair value measurements and disclosures which establishes a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). The three levels of the fair value hierarchy under the pronouncement are described below:
	Basis of Fair Value Measurement
	Level 1 – Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities;
	Level 2 – Quoted prices in markets that are not active or financial instruments for which all significant inputs are observable, either directly or indirectly; and
	Level 3 – Prices or valuations that require inputs that are both significant to the fair value measurement and unobservable.
	A financial instrument’s level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement. In determining the appropriate levels, the Company performs an analysis of the assets and liabilities that are subject to these disclosures. At each reporting period, all assets and liabilities for which the fair value measurement is based on significant unobservable inputs or instruments which trade infrequently and therefore have little or no price transparency are classified as Level 3. Transfers between levels are recognized as of the end of the period in which they occur.
	Fair Value of Other Financial Instruments
	The Company believes that the carrying values of all other financial instruments presented in the consolidated statements of financial condition approximate their fair value generally due to their short-term nature and generally negligible credit risk. These fair value measurements would be categorized as Level 2 within the fair value hierarchy.
	Noncontrolling Interests
	The Company records the noncontrolling interests of other consolidated entities as equity in the consolidated statements of financial condition. Additionally, the consolidated statements of income separately present income allocated to both noncontrolling interests and common stockholders.
	The portion of the consolidated interests in the general partners of certain of the merchant banking funds not held by the Company is presented as noncontrolling interest in equity. See “Note 4 — Investments — Merchant Banking Funds”.
	Property and Equipment
	Property and equipment is stated at cost less accumulated depreciation and amortization. Depreciation is computed using the straight-line method over the life of the assets. Amortization of leasehold improvements is computed using the straight-line method over the lesser of the life of the asset or the remaining term of the lease. Estimated useful lives of the Company’s fixed assets are generally as follows:
	Aircraft – 7 years
	Equipment – 5 years
	Furniture and fixtures – 7 years
	Leasehold improvements – the lesser of 10 years or the remaining lease term

	Merchant Banking Funds
	In December 2009, in order to focus entirely on the advisory business, the Company sold certain assets related to the merchant banking business to GCP Capital Partners Holdings LLC (or “GCP Capital”), an entity principally owned by former Greenhill employees and independent from the Company, which took over the management of our merchant banking funds. Prior to that time, the Company's merchant banking activities consisted primarily of management of and investment in certain previously sponsored merchant banking funds: Greenhill Capital Partners (“GCP I”), Greenhill Capital Partners II (“GCP II”), Greenhill Capital Partners Europe ("GCPE"), Greenhill SAV Partners ("GSAVP") and a limited partnership interest in Greenhill Capital Partners III ("GCP III"). In 2011, the Company began the monetization of these assets.
	In 2011, the Company sold substantially all of its capital interests in GCP II to unaffiliated third parties and certain principals of GCP Capital for an aggregate purchase price of $44.8 million, which represented the Company’s book value of such capital interests. The transaction agreement provided that the purchasers had the right, exercisable in December 2012, to cause the Company to repurchase each of the capital account interests attributable to two specified portfolio companies of GCP II, at a specified aggregate price of $14.3 million, subject to adjustments for distributions or capital calls (the “Put Options”). In June 2012, the purchasers funded a capital call of $1.3 million related to one of the specified portfolio companies, increasing in aggregate the Put Options to $15.6 million. In December 2012, substantially all of the purchasers of the Put Options exercised their rights to have the Company repurchase their interests, which was paid prior to year end.
	Additionally in 2011, the Company sold all of its capital interests in GSAVP and its affiliated funds to an unaffiliated third party for a purchase price of $4.6 million, which represented the Company’s carrying value of such capital interests.
	In 2012, the Company sold its entire interest in GCPE for proceeds of $27.2 million, which represented approximately 90% of book value. The Company recognized a loss of $3.4 million as result of this sale.
	In July 2013, the Company sold all of its limited partnership interest in GCP III for approximately $2.0 million, which represented the book value of the investment at June 30, 2013. In connection with that sale, the purchasers assumed any remaining undrawn commitments to the fund.
	The Company recognized a gain at the time of the exit from the merchant banking business, which is amortizing over a five year period ending in 2014. For the years ended December 31, 2013, 2012 and 2011, deferred gains of $0.2 million, $0.3 million and $0.8 million were recognized, respectively.

	The carrying value of the Company’s investments in previously sponsored and other merchant banking funds are as follows:


		As of December 31,
		2013				2012
		(in thousands)
	Investment in GCP I	$	2,257			$	2,247

	Investment in GCP II	7,690				11,173

	Investment in other merchant banking funds	1,798				1,985

	Total investments in merchant banking funds	$	11,745			$	16,772

	As of December 31, 2013, the Company continues to retain control only of the general partner of GCP I and GCP II and consolidates the results of each such general partner.
	The investment in GCP I includes $0.1 million and $0.3 million at December 31, 2013 and 2012, respectively, related to the noncontrolling interests in the managing general partner of GCP I. The investment in GCP II represents the capital interest in one remaining portfolio company and also includes $0.9 million and $1.1 million at December 31, 2013 and 2012, respectively, related to the noncontrolling interests in the general partner of GCP II.
	Investments in other merchant banking funds include the Company's investment in Barrow Street III, a real estate investment fund. At December 31, 2013, $0.3 million of the Company's commitment remains unfunded and may be drawn any time prior to the expiration of the fund in June 2015.
	Iridium Common Stock
	In October 2011, the Company initiated a plan to sell its entire interest in Iridium common stock systematically over a period over two or more years. Under this plan, the Company sold 870,000 common shares of Iridium at an average price per share of $6.72 during the year ended December 31, 2011. In 2012, the Company sold an additional 3,850,000 common shares of Iridium at an average price per share of $7.91. In 2013, the Company completed the liquidation of the investment with the sale of 5,084,016 common shares of Iridium at an average price per share of $6.73. As of December 31, 2013 the Company had sold its entire interest in Iridium.
	The investment in Iridium common stock was valued at its closing quoted market price and was accounted for as a trading security since the Company did not maintain or exercise significant influence over Iridium. At December 31, 2012, the Company owned 5,084,016 shares of Iridium common stock with a quoted market price of $6.72, and had a fully diluted ownership of approximately 7%.

Revolving Bank Loan Facility	'
	At December 31, 2013, the Company had a $45.0 million revolving loan facility from a U.S. banking institution to provide for working capital needs and for other general corporate purposes. The revolving loan facility has historically been renewed annually. The maturity date of the facility is April 30, 2014. Interest on the borrowings is based on the higher of 3.25% or the U.S. Prime Rate and is payable monthly.
	The revolving loan facility is secured by any cash distributed in respect of the Company’s investment in the U.S. based merchant banking funds and cash distributions from G&Co. In addition, the revolving loan facility has a prohibition on the incurrence of additional indebtedness without the prior approval of the lenders and the Company is required to comply with certain financial and liquidity covenants. The weighted average daily borrowings outstanding under the revolving loan facility were approximately $30.0 million and $28.4 million for the years ended December 31, 2013 and 2012, respectively. The weighted average interest rate was 3.3% for the year ended December 31, 2013, 3.5% for the year ended December 31, 2012 and 4% for the year ended December 31, 2011. At December 31, 2013, the Company was compliant with all loan covenants.

	Dividends declared per common share were $1.80 for each of the years ended December 31, 2013, 2012 and 2011 and are paid on outstanding common shares. In addition, dividends equivalent amounts are paid on outstanding restricted stock units and amounted to $6.2 million, $5.6 million and $4.8 million for the year ended December 31, 2013, 2012 and 2011, respectively, and are included in dividends paid on the consolidated statements of cash flows. In the event a restricted stock unit holder’s employment is terminated, a portion of the dividend equivalent may be required to be paid back (a "clawback") to the Company and is netted against the dividend equivalent amounts. See “Note 12 — Restricted Stock Units”.
	During 2013, 693,691 restricted stock units vested and were issued as common stock of which the Company is deemed to have repurchased 226,505 shares at an average price of $56.83 per share in conjunction with the payment of tax liabilities in respect of stock delivered to its employees in settlement of restricted stock units. In addition, during 2013 the Company repurchased in open market transactions 853,870 shares of its common stock at an average price of $49.81.
	During 2012, 654,612 restricted stock units vested and were issued as common stock of which the Company is deemed to have repurchased 181,820 shares at an average price of $45.29 per share in conjunction with the payment of tax liabilities in respect of stock delivered to its employees in settlement of restricted stock units. In addition, during 2012 the Company repurchased in open market transactions 1,714,614 shares of its common stock at an average price of $43.70.
	In connection with the acquisition of Greenhill Australia in April 2010, the Company issued 1,099,877 shares of contingent convertible preferred stock ("Performance Stock"). The Performance Stock does not pay dividends, was issued in tranches of 659,926 shares and 439,951 shares, and converts to shares of the Company’s common stock promptly after the third and fifth anniversaries of the closing of the acquisition, respectively, if certain separate revenue targets are achieved. During 2012, the revenue target for the first tranche was achieved and on April 1, 2013, the third anniversary of the closing, 659,926 shares of Performance Stock, which had a fair value of $32.5 million at the acquisition date, were converted to common stock. See "Note 10 — Earnings per Share".
	In addition, at the closing of the acquisition of Greenhill Australia, the Company granted performance based restricted stock units (“Performance RSUs”), that are subject to the same revenue targets as the Performance Stock. The Performance RSUs vest in tranches of 62,690 and 41,794 shares on the third and fifth anniversaries of the closing, respectively, subject to the achievement of the same revenue targets as the Performance Stock. Amortization of each tranche of the Performance RSUs begins at the time it is deemed probable that the revenue targets will be achieved and the value of the award at that date is amortized over the remaining vesting period of each award. If those revenue targets are not achieved, the Performance RSUs will be canceled and no amount will be expensed. As a result, on April 1, 2013, the revenue target was achieved and 62,690 shares vested. For the years ended December 31, 2013, 2012 and 2011, the Company expensed $0.4 million, $1.7 million and $3.0 million respectively, related to the first tranche of Performance RSUs. The Company did not incur an expense related to the second tranche in the years ended December 31, 2013, 2012 or 2011.

Compensation and Retirement Disclosure [Abstract]	'
Retirement Plan	'
	In the U.S., the Company sponsors a qualified defined contribution plan (the “Retirement Plan”) covering all eligible employees of G&Co. The Retirement Plan provides for both employee contributions in accordance with Section 401(k) of the Internal Revenue Code, and employer discretionary profit sharing contributions, subject to statutory limits. Participants may contribute up to 50% of eligible compensation, as defined. The Company provides matching contributions of up to $1,000 per employee. The Company incurred costs of $0.2 million, $0.3 million and $0.3 million for contributions to the Retirement Plan for the years ended December 31, 2013, 2012 and 2011, respectively. There was $0.2 million and $0.1 million related to contributions due to the Retirement Plan included in compensation payable at December 31, 2013 and 2012, respectively.
	GCI also operates a defined contribution pension fund for its employees. The assets of the pension fund are held separately in an independently administered fund. For the years ended December 31, 2013, 2012 and 2011, GCI incurred costs of approximately $0.6 million, $0.7 million and $0.6 million, respectively. At December 31, 2013 and 2012, there were no amounts related to contributions due to the defined contribution pension fund included in compensation payable.
	Greenhill Australia is required by Australian law to contribute compulsory superannuation on employees' gross earnings, generally at a rate of 9%, subject to an annual limit per employee. Superannuation is a defined contribution plan in which retirement benefits are determined by the contribution accumulated over the working life plus investment earnings within the fund less expenses. Greenhill Australia incurred such costs of approximately $0.5 million, $0.6 million and $0.6 million for the years ended December 31, 2013, 2012 and 2011, respectively. At December 31, 2013 and 2012, there were no amounts related to superannuation contributions due to the defined contribution plan included in compensation payable.

Restricted Stock Units	'
	The Company has adopted an equity incentive plan to motivate its employees and allow them to participate in the ownership of its stock. Under the Company’s plan, restricted stock units, which represent a right to a future payment equal to one share of common stock, may be awarded to employees, directors and certain other non-employees as selected by the Compensation Committee. Awards granted under the plan generally vest ratably over a period of five years beginning on the first anniversary of the grant date or in full on the fifth anniversary of the grant date. To the extent the restricted stock units are outstanding at the time a dividend is paid on the common stock, a dividend equivalent amount is paid to the holders of the restricted stock units. In the event that the holder’s employment is terminated under circumstances in which units awarded under the plan are forfeited, beginning with grants awarded in 2009, any dividend equivalent payments related to such forfeiture, which are unvested for accounting purposes, are required to be repaid to the Company.
	The activity related to the restricted stock units is set forth below:

	For the years ended December 31, 2013, 2012 and 2011, the Company recognized compensation expense from the amortization of restricted stock units, net of forfeitures, of $56.1 million, $54.2 million and $52.8 million, respectively.
	The weighted-average grant date fair value for restricted stock units granted during the years ended December 31, 2013, 2012 and 2011 was $57.95, $47.72 and $72.75, respectively. As of December 31, 2013, unrecognized restricted stock units compensation expense was approximately $82.0 million, with such unrecognized compensation expense expected to be recognized over a weighted average period of approximately 1.8 years.
	The Company issues restricted stock units to employees under the equity incentive plan, primarily in connection with its annual bonus awards and compensation agreements for new hires. In certain jurisdictions, the Company may settle share-based payment awards in cash in lieu of shares of common stock to obtain tax deductibility. In these circumstances, the awards are settled in the cash equivalent value of the Company's shares of common stock based upon their value at settlement date. These cash settled share-based awards are classified as liabilities and are remeasured at fair value at each reporting period.
	During the year ended December 31, 2013, 3,281 shares were settled in cash for $0.2 million and the Company recognized an expense of $0.8 million, net of a reduction to expense of $0.1 million for fair value adjustments. Liabilities of $1.1 million and $0.4 million have been recorded as of December 31, 2013 and 2012, respectively, and are included in compensation payable on the consolidated statements of financial condition for future cash settlements. There were no cash settlements of restricted stock awards for the year ended December 31, 2012, other than those made in conjunction with the payment of tax liabilities.

	The Company is subject to U.S. federal, foreign, state and local corporate income taxes.
	The components of the provision for income taxes reflected on the consolidated statements of income are set forth below:


		For The Years Ended December 31,

	Total tax expense	$	24,524			$	28,383		$	24,086


	The Company's non-U.S. subsidiary earnings are not considered to be permanently reinvested outside of the United States, and under the requirements of ASC 740, the Company provides residual U.S. deferred tax to these earnings to the extent they cannot be repatriated in a tax-free manner. In 2013 and 2012, the Company did not incur any additional tax liabilities, net of credits for foreign taxes paid on such earnings, related to this policy.
	Deferred income taxes reflect the net tax effects of temporary differences between the financial reporting and tax bases of assets and liabilities as well as operating loss carryforwards. Deferred income taxes are measured using the enacted tax rates and laws that will be in effect when such differences are expected to reverse. Significant components of the Company's net deferred tax assets and liabilities are set forth below:



		As of December 31,
		2013				2012
		(in thousands)
	Deferred tax assets:
	Compensation and benefits	$	39,991			$	38,445

	Depreciation and amortization	3,077				2,883

Based on the Company's historical taxable income and its expectation for taxable income in the future, management expects that its largest deferred tax asset, which relates principally to compensation expense deducted for book purposes but not yet deducted for tax purposes, will be realized as offsets to (i) the realization of its deferred tax liabilities and (ii) future taxable income.
The Company’s deferred taxes for operating loss carryforwards relate to losses incurred in foreign jurisdictions, which either were profitable in prior years or were profitable in the current year. When assessing the need for a valuation allowance, management evaluates each foreign jurisdiction separately and considers items such as estimated future taxable income, cost bases, and other various factors. Based on all available information, the Company has determined that it is more likely than not that it will realize the benefit of these operating loss carryforwards in future periods, therefore, a valuation allowance has not been established for these deferred tax assets. At December 31, 2013, the Company had operating foreign loss carryforwards, which in aggregate totaled $7.8 million. Operating foreign loss carryforwards of $1.8 million may be carried forward for seven to eight years and the remaining $6.0 million may be carried forward for seventeen years and longer.
Due to the Company’s operating loss carryforward position, tax benefits related to share-based payments generally booked through equity accounts may not be recorded until such time as the benefit is realized as a reduction in the Company’s actual taxes paid. As of December 31, 2013, the current taxes payable would have been decreased by $0.8 million if the Company had been able to realize these benefits in its filed tax returns.
In 2013, the Company's subsidiary in the United Kingdom sold its investment in Iridium and realized a capital loss. The Company did not have capital gains in the United Kingdom to offset this capital loss, so it will be carried forward and added to the 2012 capital loss realized from the sale of its interests in GCPE. Capital losses in the United Kingdom may be carried forward indefinitely, but it is more likely than not that the Company will not generate capital gains in this jurisdiction to offset these capital losses. As such, the Company established valuation allowances of $2.8 million and $1.9 million for the tax years ending December 31, 2013 and 2012, respectively, against the deferred tax asset related to its capital losses in the United Kingdom until such time as it determines it is more likely than not that the tax benefit of this deferred tax asset will be realized.
The Company has U.S. foreign tax credit carryforwards of $4.3 million and $6.2 million as of December 31, 2013 and 2012, respectively, which can be utilized against the repatriation of earnings from foreign jurisdictions. The repatriation of all foreign earnings as of December 31, 2013 would result in $2.2 million of additional federal tax. Although the Company expects to repatriate foreign earnings in the future, it is not practicable to estimate the U.S. tax effect of future repatriations of its foreign earnings. As such, as of December 31, 2013 and 2012, the Company has established valuation allowances of $2.1 million and $5.7 million, respectively, against the portion of its U.S. foreign tax credit carryforward which may not be utilized until it can determine it is more likely than not that the tax benefit of this deferred tax asset will be realized. These foreign tax credit carryforwards will expire in various years through 2022 if not utilized.
Any gain or loss resulting from the translation of deferred taxes for foreign affiliates is included in the foreign currency translation adjustment incorporated as a component of other comprehensive income, net of tax, in the consolidated statements of changes in equity. There are income taxes receivable of $1.5 million included in other receivables in the consolidated statements of financial condition as of December 31, 2013, and none as of December 31, 2012. Included in current income taxes payable in the consolidated statements of financial condition are current taxes payable of $15.3 million as of December 31, 2013 and $15.8 million as of December 31, 2012.
The Company is subject to the income tax laws of the United States, its states and municipalities, and those of the foreign jurisdictions in which the Company operates. These laws are complex, and the manner which they apply to the taxpayer's facts is sometimes open to interpretation. Management must make judgments in assessing the likelihood that a tax position will be sustained upon examination by the taxing authorities based on the technical merits of the tax position. In the normal course of business, the Company may be under audit in one or more of its jurisdictions in an open tax year for that particular jurisdiction. As of December 31, 2013, the Company does not expect any material changes in its tax provision related to any outstanding current or future audits.
The Company recognizes tax positions in the financial statements only when it is more likely than not that the position will be sustained on examination by the relevant taxing authority based on the technical merits of the position. A position that meets this standard is measured at the largest amount of benefit that will more likely than not be realized on settlement. A liability is established for differences between positions taken in a tax return and amounts recognized in the financial statements. The Company performed a tax analysis as of December 31, 2013, and determined that there was no requirement to accrue any material additional liabilities. Also, when present as part of the tax provision calculation, interest and penalties are reported as interest expense and other operating expenses in the consolidated statements of income.
A reconciliation of the statutory U.S. federal income tax rate of 35.0% to the Company’s effective income tax rate is set forth below:


	For the Years Ended December 31,
	2013			2012			2011

Business Information	'
	Business Information
	The Company’s activities as an investment banking firm constitutes a single business segment, with two principal sources of revenue:

	•	Advisory, which includes engagements relating to mergers and acquisitions, financing advisory and restructuring, and private equity and real estate capital advisory services; and

	•	Investments, which includes the Company's principal investments in certain merchant banking funds, Iridium, other investments and interest income.
	The Company has principally earned its revenues from advisory fees earned from clients in large part upon the successful completion of the client’s transaction or restructuring, or fund closing. Advisory revenues represented approximately 100%, 102% and 103% of the Company’s total revenues for the years ended December 31, 2013, 2012 and 2011, respectively.
	In 2013, there was one advisory client that accounted for approximately 10% of revenues (advice to Coventry Health Care, Inc. in connection with its sale to Aetna). For the years ended 2012 and 2011, there were no advisory clients that accounted for more than 10% of total revenues. The Company did not have any single gain on an investment that contributed more than 10% to total revenues in 2013, 2012 or 2011.
	Since the financial markets are global in nature, the Company generally manages its business based on the operating results of the enterprise taken as whole, not by geographic region. For reporting purposes, the geographic regions are the Americas, Europe, Australia, and Asia, locations in which the Company retains substantially all of its employees.
	The following table presents information about the Company by geographic region, after elimination of all significant inter-company accounts and transactions:

Summary of Significant Accounting Policies (Policies)	Dec. 31, 2013
Accounting Policies [Abstract]	'
Organization, Consolidation, Basis of Presentation, Business Description and Accounting Policies [Text Block]	'
	Basis of Financial Information
	These consolidated financial statements are prepared in conformity with accounting principles generally accepted in the United States (U.S. GAAP), which require management to make estimates and assumptions regarding future events that affect the amounts reported in our financial statements and these footnotes, including investment valuations, compensation accruals and other matters. Management believes that the estimates used in preparing its consolidated financial statements are reasonable and prudent. Actual results could differ materially from those estimates. Certain reclassifications have been made to prior year information to conform to current year presentation.
	The consolidated financial statements of the Company include all consolidated accounts of Greenhill & Co., Inc. and all other entities in which the Company has a controlling interest after eliminations of all significant inter-company accounts and transactions. In accordance with the accounting pronouncements related to consolidation of variable interest entities, the Company consolidates the general partners of certain merchant banking funds in which it has a majority of the economic interest and control. The general partners account for their investments in these merchant banking funds under the equity method of accounting. As such, the general partners record their proportionate shares of income (loss) from the underlying merchant banking funds. As these merchant banking funds follow investment company accounting, and generally record all their assets and liabilities at fair value, the general partners’ investment in these merchant banking funds represents an estimation of fair value. The Company does not consolidate the merchant banking funds since the Company, through its general partner and limited partner interests, does not have a majority of the economic interest in such funds and the limited partners have certain rights to remove the general partner by a simple majority vote of unaffiliated third-party investors.
Revenue Recognition	'
	Revenue Recognition
	Advisory Revenues

	It is the Company's accounting policy to recognize revenue when (i) there is persuasive evidence of an arrangement with a client, (ii) the agreed-upon services have been completed and delivered to the client or the transaction or events noted in the engagement letter are determined to be substantially complete, (iii) fees are fixed and determinable, and (iv) collection is reasonably assured.

	The Company recognizes advisory fee revenues for mergers and acquisitions or financing advisory and restructuring engagements when the services related to the underlying transactions are completed in accordance with the terms of the engagement letter and all other requirements for revenue recognition are satisfied.

	The Company recognizes private equity and real estate capital advisory fees at the time of the client's acceptance of capital or capital commitments to a fund in accordance with the terms of the engagement letter. Generally, fee revenue is determined based upon a fixed percentage of capital committed to the fund. For multiple closings, revenue is recognized at each interim closing based on the amount of capital committed at each closing at the fixed fee percentage. At the final closing, revenue is recognized at the fixed percentage for the amount of capital committed since the last interim closing.

	While the majority of the Company's fee revenue is earned at the conclusion of a transaction or closing of a fund, on-going retainer fees, substantially all of which relate to non-success based strategic advisory and financing advisory and restructuring assignments, are also earned and recognized as advisory fee revenue over the period in which the related service is rendered.

	The Company’s clients reimburse certain expenses incurred by the Company in the conduct of advisory engagements. Expenses are reported net of such client reimbursements. Client reimbursements totaled $6.5 million, $7.4 million and $6.5 million for the years ended December 31, 2013, 2012, and 2011, respectively.
	Investment Revenues
	Investment revenues consist of (i) gains (or losses) on the Company's investments in certain merchant banking funds, Iridium and other investments, and (ii) interest income.
	The Company recognizes revenue on its investments in merchant banking funds based on its allocable share of realized and unrealized gains (or losses) reported by such funds. The Company recognizes revenue on its other investments, including Iridium, which considers the Company's influence or control of the investee, based on gains and losses on investment positions held, which arise from sales or changes in the fair value of investments. The amount of gains or losses are not predictable and can cause periodic fluctuations in net income and therefore subject the Company to market and credit risk.
Cash and Cash Equivalents	'
	Cash and Cash Equivalents
	The Company’s cash and cash equivalents consist of (i) cash held on deposit with financial institutions, (ii) cash equivalents and (iii) restricted cash. The Company maintains its cash and cash equivalents with financial institutions with high credit ratings. The Company considers all highly liquid investments with a maturity date of three months or less, when purchased, to be cash equivalents. Cash equivalents primarily consist of money market funds and overnight deposits.
	Management believes that the Company is not exposed to significant credit risk due to the financial position of the depository institutions in which those deposits are held. See "Note 3 — Cash and Cash Equivalents".
Advisory Fees Receivables	'
	Advisory Fees Receivables
	Receivables are stated net of an allowance for doubtful accounts. The estimate for the allowance for doubtful accounts is derived by the Company by utilizing past client transaction history and an assessment of the client’s creditworthiness. The Company did not record a bad debt expense in any of the years ended December 31, 2013, 2012 or 2011.
	Included in the advisory fees receivable balance at December 31, 2013 and 2012 were $34.0 million and $29.8 million of long term receivables related to private equity and real estate capital advisory engagements which are generally paid in installments over a period of three years. Included as a component of investment revenues on the consolidated statements of income is interest income related to capital advisory engagements of $0.8 million, $1.2 million and $0.1 million for the years ended December 31, 2013, 2012 and 2011, respectively.
	Credit risk related to advisory fees receivable is disbursed across a large number of clients located in various geographic areas. The Company controls credit risk through credit approvals and monitoring procedures but does not require collateral to support accounts receivable.
Investments	'
	Investments
	The Company's investments in merchant banking funds are recorded under the equity method of accounting based upon the Company's proportionate share of the estimated fair value of the underlying merchant banking fund's net assets. The value of merchant banking fund investments in privately held companies is determined by management of the fund after giving consideration to the cost of the security, the pricing of other sales of securities by the portfolio company, the price of securities of other companies comparable to the portfolio company, purchase multiples paid in other comparable third-party transactions, the original purchase price multiple, market conditions, liquidity, operating results and other qualitative and quantitative factors. Discounts may be applied to the funds' privately held investments to reflect the lack of liquidity and other transfer restrictions. Investments in publicly traded securities are valued using quoted market prices discounted for any legal or contractual restrictions on sale. Because of the inherent uncertainty of valuations as well as the discounts applied, the estimated fair values of investments in privately held companies may differ significantly from the values that would have been used had a ready market for the securities existed. The values at which the Company's investments are carried on its consolidated statements of financial condition are adjusted to estimated fair value at the end of each quarter and the volatility in general economic conditions, stock markets and commodity prices may result in significant changes in the estimated fair value of the investments from period to period.
Goodwill	'
	Goodwill
	Goodwill is the cost in excess of the fair value of identifiable net assets at acquisition date. The Company tests its goodwill for impairment at least annually. An impairment loss is triggered if the estimated fair value of an operating unit is less than estimated net book value. Such loss is calculated as the difference between the estimated fair value of goodwill and its carrying value.
	Goodwill is translated at the rate of exchange prevailing at the end of the periods presented in accordance with the accounting guidance for foreign currency translation. Any translation gain or loss is included in the foreign currency translation adjustment, which is included as a component of other comprehensive income in the consolidated statements of changes in equity.
Restricted Stock Units	'
	Restricted Stock Units
	The Company accounts for its share-based compensation payments by recording the fair value of restricted stock units granted to employees as compensation expense. The restricted stock units are generally amortized over a five-year service period following the date of grant. Compensation expense is determined based upon the fair market value of the Company’s common stock at the date of grant. As the Company expenses the awards, the restricted stock units recognized are recorded within equity. The restricted stock units are reclassified into common stock and additional paid-in capital upon vesting. The Company records as treasury stock the repurchase of stock delivered to its employees in settlement of tax liabilities incurred upon the vesting of restricted stock units. The Company records dividend equivalent payments, net of estimated forfeitures, on outstanding restricted stock units as a dividend payment and a charge to equity.
Earnings per Share	'
	Earnings per Share
	The Company calculates basic earnings per share (“EPS”) by dividing net income allocated to common stockholders by the sum of (i) the weighted average number of shares outstanding for the period and (ii) the weighted average number of shares deemed issuable due to the vesting of restricted stock units for accounting purposes. In addition, the contingent convertible preferred shares will also be included in the weighted average number of shares to the extent they are deemed to have met the performance targets. See "Note 9 — Equity".
	The Company calculates diluted EPS by dividing net income allocated to common stockholders by the sum of (i) basic shares per above and (ii) the dilutive effect of the common stock deliverable pursuant to restricted stock units for which future service is required. Under the treasury method, the number of shares issuable upon the vesting of restricted stock units included in the calculation of diluted EPS is the excess, if any, of the number of shares expected to be issued, less the number of shares that could be purchased by the Company with the proceeds to be received upon settlement at the average market closing price during the reporting period.
Provision for Taxes	'
	Provision for Taxes
	The Company accounts for taxes in accordance with the accounting guidance for income taxes, which requires the recognition of tax benefits or expenses on the temporary differences between the financial reporting and tax bases of its assets and liabilities.
	The Company follows the guidance for income taxes in recognizing, measuring, presenting and disclosing in its financial statements uncertain tax positions taken or expected to be taken on its income tax returns. Income tax expense is based on pre-tax accounting income, including adjustments made for the recognition or derecognition related to uncertain tax positions. The recognition or derecognition of income tax expense related to uncertain tax positions is determined under the guidance.
	Deferred tax assets and liabilities are recognized for the future tax attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in earnings in the period of change. Management applies the “more-likely-than-not criteria” when determining tax benefits.
Foreign Currency Translation	'
	Foreign Currency Translation
	Assets and liabilities denominated in foreign currencies have been translated at rates of exchange prevailing at the end of the periods presented in accordance with the accounting guidance for foreign currency translation. Income and expenses transacted in foreign currency have been translated at average monthly exchange rates during the period. Translation gains and losses are included in the foreign currency translation adjustment, which is included as a component of other comprehensive income (loss) in the consolidated statement of changes in equity. Foreign currency transaction gains and losses are included in the consolidated statements of income.
Financial Instruments and Fair Value	'
	Financial Instruments and Fair Value
	The Company accounts for financial instruments measured at fair value in accordance with accounting guidance for fair value measurements and disclosures which establishes a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). The three levels of the fair value hierarchy under the pronouncement are described below:
	Basis of Fair Value Measurement
	Level 1 – Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities;
	Level 2 – Quoted prices in markets that are not active or financial instruments for which all significant inputs are observable, either directly or indirectly; and
	Level 3 – Prices or valuations that require inputs that are both significant to the fair value measurement and unobservable.
	A financial instrument’s level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement. In determining the appropriate levels, the Company performs an analysis of the assets and liabilities that are subject to these disclosures. At each reporting period, all assets and liabilities for which the fair value measurement is based on significant unobservable inputs or instruments which trade infrequently and therefore have little or no price transparency are classified as Level 3. Transfers between levels are recognized as of the end of the period in which they occur.
	Fair Value of Other Financial Instruments
	The Company believes that the carrying values of all other financial instruments presented in the consolidated statements of financial condition approximate their fair value generally due to their short-term nature and generally negligible credit risk. These fair value measurements would be categorized as Level 2 within the fair value hierarchy.
Noncontrolling Interests	'
	Noncontrolling Interests
	The Company records the noncontrolling interests of other consolidated entities as equity in the consolidated statements of financial condition. Additionally, the consolidated statements of income separately present income allocated to both noncontrolling interests and common stockholders.
	The portion of the consolidated interests in the general partners of certain of the merchant banking funds not held by the Company is presented as noncontrolling interest in equity. See “Note 4 — Investments — Merchant Banking Funds”.
Property and Equipment	'
	Property and Equipment
	Property and equipment is stated at cost less accumulated depreciation and amortization. Depreciation is computed using the straight-line method over the life of the assets. Amortization of leasehold improvements is computed using the straight-line method over the lesser of the life of the asset or the remaining term of the lease. Estimated useful lives of the Company’s fixed assets are generally as follows:
	Aircraft – 7 years
	Equipment – 5 years
	Furniture and fixtures – 7 years
	Leasehold improvements – the lesser of 10 years or the remaining lease term
