	1	Description of business, basis of presentation and recent accounting pronouncements
	Description of Business
	Marcus & Millichap, Inc., (the “Company”, “Marcus & Millichap”, or “MMI”), a Delaware corporation, is a brokerage firm specializing in commercial real estate investment sales, financing, research and advisory services.  As of September 30,2014, MMI operates 78 offices in the United States and Canada through its two wholly-owned subsidiaries, Marcus & Millichap Real Estate Investment Services, Inc. (“MMREIS”) and Marcus & Millichap Capital Corporation (“MMCC”).
	Reorganization and Initial Public Offering
	MMI was formed in June 2013 in preparation for Marcus & Millichap Company (“MMC”) to spin-off its majority owned subsidiary, MMREIS (“Spin-Off”). Prior to the initial public offering (“IPO”) of MMI stock on October 30, 2013, all of the preferred and common stockholders of MMREIS (including MMC and employees of MMREIS) contributed all of their outstanding shares to the Company, in exchange for new MMI common stock, and MMREIS became MMI’s wholly-owned subsidiary. Thereafter, MMC distributed 80.0% of the shares of MMI common stock to MMC’s shareholders and exchanged the remaining portion of its shares of MMI common stock for cancellation of indebtedness of MMC.
	Prior to the Spin-Off, MMI and MMREIS were affiliates under common control, and the assets and liabilities of MMREIS were recorded at carryover basis at the Spin-Off date. The historical financial statements of MMREIS, as the Company’s predecessor, have been presented as the historical financial statements of the Company for all periods prior to the Spin-Off from the beginning of the earliest period presented.
	On November 5, 2013, MMI completed its Initial Public Offering (“IPO”) of 6,900,000 shares of common stock at a price to the public of $12.00 per share.
	Basis of Presentation
	The financial information presented in the accompanying unaudited condensed consolidated financial statements, have been prepared in accordance with rules and regulations of the U.S. Securities and Exchange Commission (“SEC”) for quarterly reports on Form 10–Q and Article 10-01 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by U.S. generally accepted accounting principles (“GAAP”) for complete financial statements. In the opinion of management, the accompanying unaudited condensed consolidated financial statements and notes include all adjustments (consisting only of normal recurring adjustments) necessary for a fair presentation of the consolidated financial position, results of operations and cash flows for the periods presented. These unaudited condensed consolidated financial statements should be read in conjunction with the annual audited consolidated financial statements and notes thereto for the year ended December 31, 2013 included in the Company’s Annual Report on Form 10-K filed on March 21, 2014, with the SEC. The results of the three and nine months ended September 30, 2014 are not necessarily indicative of the results to be expected for the fiscal year ending December 31, 2014, or for other interim periods or future years.
	Consolidation
	The accompanying condensed consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All significant intercompany balances and transactions have been eliminated in consolidation.
	Use of Estimates
	The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the related disclosures at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.
	Reclassifications
	Certain prior-period amounts in the notes to condensed consolidated financial statements and condensed consolidated statements of cash flows have been reclassified to conform to the current period presentation. These changes had no impact on the previously reported consolidated results of operations, financial condition, stockholders’ equity or on cash flows subtotals.
	Concentration of Credit Risk
	Financial instruments that potentially subject the Company to a concentration of credit risk principally consist of cash and cash equivalents and commissions receivable. Cash is placed with high-credit quality financial institutions. To reduce its credit risk, the Company monitors the credit standing of the financial institutions that hold the Company’s cash and cash equivalents. The Company historically has not experienced any losses in its cash and cash equivalents. For commissions and other receivable, net the Company maintains allowances for estimated credit losses based on management’s assessment of the likelihood of collection. As of September 30, 2014 and December 31, 2013, the Company does not have significant concentration of credit risk.
	The Company derives its revenues from a broad range of real estate investors and owners in the United States and Canada, none of which individually represents a significant concentration of credit risk. For the three and nine months ended September 30, 2014 and 2013, no individual transaction represented 10% or more of total revenues.
	Recent Accounting Pronouncements
	In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2014-09, Revenue from Contracts with Customers (“ASU 2014-09”), which supersedes virtually all of the current revenue recognition guidance under U.S. GAAP, and requires entities to recognize revenue for transfer to customer of promised goods or services in an amount that reflects the consideration to which the entity expects to be entitled to receive in exchange for those goods or services. ASU 2014-09 is effective for reporting periods beginning after December 15, 2016 and early adoption is not permitted. ASU 2014-09 permits two implementation approaches, one requiring retrospective application of the new standard with restatement of prior years and one requiring prospective application of the new standard with disclosure of results under old standards. For the Company, the new standard will be effective January 1, 2017. The Company is currently evaluating the impact of this new standard.
	In August 2014, the FASB issued ASU No. 2014-15, Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern (“ASU 2014-15”). Currently, there is no guidance under U.S. GAAP regarding management’s responsibility to assess whether there is substantial doubt about an entity’s ability to continue as a going concern. Under ASU 2014-15, the Company will be required to assess its ability to continue as a going concern each interim and annual reporting period and provide certain disclosures if there is substantial doubt about the entity’s ability to continue as a going concern, including management’s plan to alleviate the substantial doubt. ASU 2014-15 is effective for reporting periods beginning after December 15, 2016 and early adoption is permitted. For the Company, the new standard will be effective January 1, 2017. This new standard will not have an impact to the Company’s consolidated financial position or results of operations.

	SARs Liability
	Prior to the IPO, certain employees of the Company were granted stock appreciation rights (“SARs”) under a stock-based compensation program assumed by MMC (“Program”). The SARs agreements were revised and the MMC liability of $20.0 million for the SARs was frozen at March 31, 2013, and was ultimately transferred to MMI through a capital contribution. The SARs liability will be settled with each participant in installments upon retirement or departure. Under the revised agreements, MMI is required to accrue interest on the outstanding balance beginning on January 1, 2014 at a rate based on the 10-year treasury note plus 2%. The rate resets annually. The rate at January 2, 2014 was 5.03%, and MMI recorded interest expense related to this liability of $236,000 and $738,000 for the three and nine months ended September 30, 2014, respectively.
	During the three months ended September 30, 2014, the Company reduced the SARs liability balance in the amount of $412,000 related to a distribution for the settlement of FICA taxes payable on behalf of certain participants.
	Commissions Payable
	Certain investment sales professionals have the ability to earn additional commissions after meeting certain annual revenue thresholds. These commissions are recognized as cost of services in the period in which they are earned. The Company has the ability to defer payment of certain commissions, at its election, for up to three years. Commissions payable that are not expected to be paid within twelve months are classified as long-term liabilities.
	Deferred Compensation Liability
	A select group of management is eligible to participate in a Deferred Compensation Plan. The plan is a 409A plan and permits the participant to defer compensation up to limits as determined by the plan. The Company elected to fund the Deferred Compensation Plan through Company owned variable life insurance policies. The Deferred Compensation Plan is managed by a third-party institutional fund manager, and the deferred compensation and investment earnings are held as a Company asset in a rabbi trust, which is recorded in investments held in rabbi trust caption in the accompanying condensed consolidated balance sheets. The assets in the trust are restricted unless the Company becomes insolvent, as defined in the Deferred Compensation Plan, in which case the trust assets are subject to the claims of MMI’s creditors. The Company may also, in its sole and absolute discretion, elect to withdraw at any time all or a portion of the trust assets by an amount by which the fair market value of the trust assets exceeds 110% of the aggregate amount credited to the Deferred Compensation Plan’s participants’ accounts.
	The net change in the carrying value of the investment assets and the related obligation are recorded in other (expense) income, net and selling, general, and administrative expense, respectively in the condensed consolidated statements of net and comprehensive income and were not material during the three and nine months ended September 30, 2014 and 2013.

The Credit Agreement provides for a $60.0 million principal amount senior secured revolving credit facility that is guaranteed by all of the Company’s domestic subsidiaries (the “Credit Facility”), which matures on June 1, 2017.

Fair Value Measurements	'
	7	Fair Value Measurements
	ASC 820, Fair Value Measurement (“ASC 820”) establishes the accounting guidance for fair value measurements that applies to all financial assets and financial liabilities that are being measured and reported on a fair value basis. Under the accounting guidance, the Company makes fair value measurements that are classified and disclosed in one of the following three categories:
	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 inputs which are observable, either directly or indirectly, for substantially the full term of the asset or liability, or
	Level 3: Inputs reflect management’s best estimate of what market participants would use in pricing the asset or liability at the measurement date. Consideration is given to the risk inherent in the valuation technique and the risk inherent in the inputs to the model.
	Investments held in a rabbi trust are carried at fair value and considered to be in the Level 1.
	Fair Value of Financial Instruments
	The Company’s cash and cash equivalents, commissions and other receivables, net, accounts payable and accrued expenses and commissions payable, are carried at cost, which approximates fair value based on their immediate or short-term maturities and terms that approximate current market terms and these financial instruments are considered to be in the Level 1 classification.
	As the Company’s obligations under notes payable to former stockholders and certain employee and agent notes receivable bear fixed interest rates that approximate the rates currently offered to the Company for similar debt instruments, the Company has determined that the carrying value on these instruments approximates fair value. As the Company’s obligations under SARs liability (included in deferred compensation and commissions caption) bear variable interest rates, the Company has determined that the carrying value approximates the fair value. These are considered to be in the Level 1 classification.

	Prior to the IPO
	Restricted Common Stock and SARs
	Prior to the IPO, MMREIS granted options and SARs under a stock-based compensation award program (the “Program”). The options were exercisable into shares of unvested restricted common stock. The Program was administered by the board of directors. The board determined the terms of an award, including the amount, number of rights or shares, and vesting period, among others. Options issued generally had terms of one year or less. Restricted common stock issued upon exercise of stock options generally vested over three to five years, and stock options typically were exercised immediately for a note receivable. The exercise price of the options was based upon a formula equivalent to the net book value of common stock as of the end of the fiscal year immediately preceding the date of issuance.
	During the three and nine months ended September 30, 2013, employees of MMREIS exercised 0 and 750 stock options, respectively, through the issuance of notes receivable. Cash payments on notes receivable were presented as an increase in consolidated stockholders’ equity. Such notes bore interest at a rate of 5% or 6% per annum and were due in defined installments on various remaining dates through April 15, 2016, which was consistent with the vesting periods of the restricted common stock.
	There were no redemptions or cancellations of stock options during the three and nine months ended September 30, 2013.
	Stock-Based Compensation Expense and Deemed Capital Contribution (Distribution) From MMC
	Historically, MMC assumed MMREIS’s obligation with respect to any appreciation in the value of the underlying vested awards and SARs in excess of the employees’ exercise price. MMC was deemed to make a capital contribution to MMREIS’s additional paid-in capital equal to the amount of compensation expense recorded, net of the applicable taxes. Based on the tax-sharing agreement between MMREIS and MMC, the tax deduction on the compensation expense recorded by MMREIS was allocated to MMC. MMC recorded the liability related to the appreciation in the value of the underlying stock and SARs in its consolidated financial statements. To the extent of any depreciation in the value of the underlying vested awards and SARs (limited to the amount of any appreciation previously recorded from the employees’ original exercise price), compensation expense was reduced and MMC was deemed to receive a capital distribution.
	The total compensation cost related to unvested stock and SARs was generally recognized over approximately four years.
	In conjunction with the IPO, the vesting of all unvested restricted stock and all unvested SARs was accelerated. Following the IPO, future equity award issuances are recorded by the Company.
	During the three and nine months ended September 30, 2013, the Company recorded a capital contribution, net of taxes of $1.2 million and $2.7 million, respectively, related to total stock based compensation expense of $2.1 million and $4.7 million, respectively.
	Amendments to Restricted Stock and SARs
	The SARs were frozen at the liability amount, calculated as of March 31, 2013, which will be paid out to each participant in installments upon retirement or departure under the terms of the revised SARs agreements. See Note 3-“Selected Balance Sheet Data” for additional information. To replace beneficial ownership in the SARs, the difference between the book value liability and the fair value of the awards was granted to plan participants in the form of DSUs, which were fully vested upon receipt and will be settled in actual stock at a rate of 20% per year if the participant remains employed by the Company during that period (or otherwise all unsettled shares of stock upon termination of employment will be settled five years from the termination date). In addition, the formula settlement value of all outstanding shares of stock held by the plan participants was removed, and all such shares of stock are subject to sales restrictions that lapse at a rate of 20% per year for five years if the participant remains employed by the Company. Additionally, in the event of death or termination of employment after reaching the age of 67, 100% of the DSUs will be settled and 100% of the shares of stock will be released from the resale restriction. Further, 100% of the shares of stock will be released from the resale restriction upon the consummation of a change of control of the Company.
	Subsequent to the IPO
	2013 Omnibus Equity Incentive Plan
	In October 2013, the board of directors adopted the 2013 Omnibus Equity Incentive Plan (the “2013 Plan”), which became effective upon the Company’s IPO. The 2013 Plan, in general authorizes for the granting of incentive stock options, nonstatutory stock options, stock appreciation rights, restricted stock awards (RSAs), restricted stock units (RSUs), performance units and performance shares to the Company’s employees, independent contractors, directors and consultants and subsidiary corporations’ employees and consultants as selected from time to time by the Company’s board of directors at its discretion.
	All RSAs vest in equal annual installments over a three year period from the date of grant. All RSUs vest in equal annual installments over a five year period from the date of grant. Any unvested awards are canceled upon termination of service.
	In connection with the approval of the 2013 Plan, the Company reserved 5,500,000 shares of common stock for the issuance of awards under the 2013 Plan. At September 30, 2014, there were 2,230,999 shares available for future grants under the Plan.

	(1)	The unrecognized compensation expense is expected to be recognized over a weighted-average period of approximately 4.18 years.
	RSUs granted to independent contractors are grants made to the Company’s sales and financing professionals, who are considered non-employees under ASC 718. Accordingly, such awards are required to be measured at fair value at the end of each reporting period until settlement. During the nine months ended September 30, 2014, stock-based compensation expense was impacted by an increase in the Company’s common stock price from $14.90 at December 31, 2013 to $30.26 at September 30, 2014.
	As of September 30, 2014, there were 2,275,747 fully vested outstanding DSUs. See “Amendments to Restricted Stock and SARs” section above and Note 11 – “Earnings Per Share” for additional information.
	Employee Stock Purchase Plan
	In 2013, the Company adopted the 2013 Employee Stock Purchase Plan (“2013 ESPP Plan”). The 2013 ESPP Plan had 366,667 shares of common stock reserved and available for issuance at September 30, 2014. The ESPP Plan qualifies under Section 423 of the IRS Code and provides for consecutive, nonoverlapping 6-month offering periods. The offering periods generally start on the first trading day on or after May 15 and November 15 of each year. The first offering period began on May 15, 2014.
	MMI determined the fair value of ESPP shares to be acquired during the first offering period using the Black Scholes option pricing model. MMI calculated the expected volatility based on the historical volatility of the Company’s common stock and the risk-free interest rate based on the U.S. Treasury yield curve in effect at the time of grant both consistent with the term of the offering period. The expected dividend yield was 0%. See Note 8 – “Stockholders’ Equity” for additional information on dividends.
	At September 30, 2014, total unrecognized compensation cost related to the ESPP Plan was $22,000 and is expected to be recognized over a weighted-average period of 0.12 years.

	10	Income Taxes
	The Company’s effective tax rate for the three and nine months ended September 30, 2014 was 41.2% for each period, compared to 43.5% for each of the three and nine months ended September 30, 2013. The Company’s estimated annual effective tax rate after discrete items for 2014 is 40.9%. The Company provides for the effects of income taxes in interim financial statements based on the Company’s estimate of the estimated annual effective tax rate for the full year, which is based on forecasted income by country where the Company operates, adjusted for the tax effects of items that relate discretely to the period, if any. The difference between the statutory tax rate and the Company’s effective tax rate is largely attributable to state income taxes and a full valuation allowance with respect to the deferred tax assets of the Company’s Canadian operations.
	The Company completed an analysis related to tax deductibility of IPO transaction costs during the three months ended June 30, 2014, which resulted in a tax benefit of $840,000. This benefit was recognized as an increase to additional paid-in capital and a reduction in current income tax payable and was realized during the three months ended September 30, 2014 as a result of the filing of the 2013 consolidated federal income tax return.
	Prior to November 1, 2013, MMREIS was part of a consolidated federal income tax return and various combined and consolidated state tax returns that were filed by MMC. MMREIS and MMC had a tax-sharing agreement whereby MMREIS was charged for income taxes using an effective tax rate of 43.5%. As part of the IPO, the tax-sharing agreement with MMC was terminated effective October 31, 2013. The amount determined under the tax-sharing agreement represented a receivable or obligation of MMREIS from (to) the MMC that MMREIS generally settled on a current basis.

	Marcus & Millichap, Inc., (the “Company”, “Marcus & Millichap”, or “MMI”), a Delaware corporation, is a brokerage firm specializing in commercial real estate investment sales, financing, research and advisory services.  As of September 30, 2014, MMI operates 78 offices in the United States and Canada through its two wholly-owned subsidiaries, Marcus & Millichap Real Estate Investment Services, Inc. (“MMREIS”) and Marcus & Millichap Capital Corporation (“MMCC”).
Reorganization and Initial Public Offering	'
	Reorganization and Initial Public Offering
	MMI was formed in June 2013 in preparation for Marcus & Millichap Company (“MMC”) to spin-off its majority owned subsidiary, MMREIS (“Spin-Off”). Prior to the initial public offering (“IPO”) of MMI stock on October 30, 2013, all of the preferred and common stockholders of MMREIS (including MMC and employees of MMREIS) contributed all of their outstanding shares to the Company, in exchange for new MMI common stock, and MMREIS became MMI’s wholly-owned subsidiary. Thereafter, MMC distributed 80.0% of the shares of MMI common stock to MMC’s shareholders and exchanged the remaining portion of its shares of MMI common stock for cancellation of indebtedness of MMC.
	Prior to the Spin-Off, MMI and MMREIS were affiliates under common control, and the assets and liabilities of MMREIS were recorded at carryover basis at the Spin-Off date. The historical financial statements of MMREIS, as the Company’s predecessor, have been presented as the historical financial statements of the Company for all periods prior to the Spin-Off from the beginning of the earliest period presented.
	On November 5, 2013, MMI completed its Initial Public Offering (“IPO”) of 6,900,000 shares of common stock at a price to the public of $12.00 per share.
Basis of Presentation	'
	Basis of Presentation
	The financial information presented in the accompanying unaudited condensed consolidated financial statements, have been prepared in accordance with rules and regulations of the U.S. Securities and Exchange Commission (“SEC”) for quarterly reports on Form 10–Q and Article 10-01 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by U.S. generally accepted accounting principles (“GAAP”) for complete financial statements. In the opinion of management, the accompanying unaudited condensed consolidated financial statements and notes include all adjustments (consisting only of normal recurring adjustments) necessary for a fair presentation of the consolidated financial position, results of operations and cash flows for the periods presented. These unaudited condensed consolidated financial statements should be read in conjunction with the annual audited consolidated financial statements and notes thereto for the year ended December 31, 2013 included in the Company’s Annual Report on Form 10-K filed on March 21, 2014, with the SEC. The results of the three and nine months ended September 30, 2014 are not necessarily indicative of the results to be expected for the fiscal year ending December 31, 2014, or for other interim periods or future years.
Consolidation	'
	Consolidation
	The accompanying condensed consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All significant intercompany balances and transactions have been eliminated in consolidation.
Use of Estimates	'
	Use of Estimates
	The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the related disclosures at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.
Reclassifications	'
	Reclassifications
	Certain prior-period amounts in the notes to condensed consolidated financial statements and condensed consolidated statements of cash flows have been reclassified to conform to the current period presentation. These changes had no impact on the previously reported consolidated results of operations, financial condition, stockholders’ equity or on cash flows subtotals.
Concentration of Credit Risk	'
	Concentration of Credit Risk
	Financial instruments that potentially subject the Company to a concentration of credit risk principally consist of cash and cash equivalents and commissions receivable. Cash is placed with high-credit quality financial institutions. To reduce its credit risk, the Company monitors the credit standing of the financial institutions that hold the Company’s cash and cash equivalents. The Company historically has not experienced any losses in its cash and cash equivalents. For commissions and other receivable, net the Company maintains allowances for estimated credit losses based on management’s assessment of the likelihood of collection. As of September 30, 2014 and December 31, 2013, the Company does not have significant concentration of credit risk.
	The Company derives its revenues from a broad range of real estate investors and owners in the United States and Canada, none of which individually represents a significant concentration of credit risk. For the three and nine months ended September 30, 2014 and 2013, no individual transaction represented 10% or more of total revenues.

ASU 2014-09 is effective for reporting periods beginning after December 15, 2016 and early adoption is not permitted. ASU 2014-09 permits two implementation approaches, one requiring retrospective application of the new standard with restatement of prior years and one requiring prospective application of the new standard with disclosure of results under old standards. For the Company, the new standard will be effective January 1, 2017. The Company is currently evaluating the impact of this new standard.
	In August 2014, the FASB issued ASU No. 2014-15, Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern (“ASU 2014-15”). Currently, there is no guidance under U.S. GAAP regarding management’s responsibility to assess whether there is substantial doubt about an entity’s ability to continue as a going concern. Under ASU 2014-15, the Company will be required to assess its ability to continue as a going concern each interim and annual reporting period and provide certain disclosures if there is substantial doubt about the entity’s ability to continue as a going concern, including management’s plan to alleviate the substantial doubt. ASU 2014-15 is effective for reporting periods beginning after December 15, 2016 and early adoption is permitted. For the Company, the new standard will be effective January 1, 2017. This new standard will not have an impact to the Company’s consolidated financial position or results of operations.
Fair Value Measurements	'
	ASC 820, Fair Value Measurement (“ASC 820”) establishes the accounting guidance for fair value measurements that applies to all financial assets and financial liabilities that are being measured and reported on a fair value basis. Under the accounting guidance, the Company makes fair value measurements that are classified and disclosed in one of the following three categories:
	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 inputs which are observable, either directly or indirectly, for substantially the full term of the asset or liability, or
	Level 3: Inputs reflect management’s best estimate of what market participants would use in pricing the asset or liability at the measurement date. Consideration is given to the risk inherent in the valuation technique and the risk inherent in the inputs to the model.
