Cash and Cash Equivalents
The Company considers cash and cash equivalents to include short-term, highly liquid investments with maturities of three months or less when purchased. At December 31, 2015 and 2014, a significant portion of the balance of cash and cash equivalents was principally held with four financial institutions and one money market fund. Management believes the likelihood of realizing material losses from the excess of cash balances over federally insured limits is remote.
Prior to its termination on June 30, 2013, the majority of the cash generated and used in the Company’s operations was subject to a treasury management service agreement which swept excess daily into MMC’s money market account. The Company was credited with interest income from MMC at the same interest rate as MMC earned on the money market account.
The Company generates real estate brokerage commissions by acting as a broker for real estate owners or investors seeking to buy or sell commercial properties. Revenues from real estate brokerage commissions are recognized when there is persuasive evidence of an arrangement, all services have been provided, the price is fixed and determinable and collectability is reasonably assured. These criteria are typically met at the close of escrow. The Company generates financing fees from securing financing on purchase transactions as well as fees earned from refinancing its clients’ existing mortgage debt and other financing activities. Revenues from financing fees are recognized at the time the loan closes and there are no remaining significant obligations for performance in connection with the transaction. Other revenues include fees generated from consulting and advisory services, as well as referral fees from other real estate brokers. Revenues from these services are recognized as the services are provided or upon closing of the transaction.
Commissions receivable consists of commissions earned on brokerage transactions for which payment has not yet been received. The Company evaluates the need for an allowance for doubtful accounts based on the specific-identification of potentially uncollectible accounts. The majority of commissions receivable are settled within 10 days after the close of escrow. As a result, the Company did not require an allowance for commissions receivable at December 31, 2015 or 2014.
Cost of Services
Cost of services principally consists of commissions and other costs for the Company’s investment sales and financing professionals related to transactions closed in the period. Investment sales and financing professionals’ commissions are generally paid on transaction revenues and includes referral and other revenues generated by the Company’s investment sales and financing professionals. Investment sales and financing professionals are compensated at commission rates based on individual agreements and portions of the commissions due may be deferred in accordance with their contracts.
Investments in Marketable Securities, Available-for-Sale
The Company maintains a portfolio of investments in a variety of fixed and variable rate securities, including U.S. treasuries U.S. government sponsored entities, corporate debt securities and asset-backed securities and other. The Company considers its investment in marketable securities to be available-for-sale. Accordingly, these investments are recorded at their fair values, with unrealized gains or losses recorded in other comprehensive income (loss), net of tax. The Company determines the appropriate classification of investments in marketable securities at the time of purchase. Interest along with accretion and amortization of purchase premiums and discounts, which are recorded over the remaining weighted average life of the security, are included in other income (expense), net in the consolidated statements of net and comprehensive income. See Note 5 – “Investments in Marketable Securities” for additional information.
The Company regularly reviews its investment portfolio to determine if any security is other-than-temporarily impaired, which would require the Company to record an impairment charge in the period any such determination is made. In making this judgment, the Company evaluates, among other items, the time frame and extent to which the fair market value of a security is less than its amortized cost and the Company’s intent and ability to sell, or whether the Company will more likely than not be required to sell, the security before recovery of its amortized cost basis. The Company has evaluated its investments in marketable securities as of December 31, 2015 and has determined that no investments with unrealized losses are other-than-temporarily impaired. The Company has no current intent to sell and it is not more likely than not that the Company will be required to sell these investments before recovery of their amortized cost basis, which may be at maturity. The Company may sell certain of its marketable securities, available-for-sale prior to their stated maturities for strategic reasons including, but not limited to, anticipation of credit deterioration and duration management.
Assets Held in Rabbi Trust
The Company provides a non-qualified deferred compensation program to certain employees. Deferred amounts are invested in variable whole life insurance policies owned by the Company for the participants benefit and held in a Rabbi Trust. Participants elect to invest in various equity and debt securities offered within the plan on a notional basis. The net change in the carrying value of the underlying assets held in the Rabbi Trust is recorded in other income (expense), net. The change in the deferred compensation liability as a result the change in the notional value of the participants accounts is recorded as a component of selling general and administrative expenses in the consolidated statements of net and comprehensive income.
Recurring Fair Value Measurements
The Company carries its investments including investments in marketable securities, available-for-sale and assets held in the Rabbi Trust at fair value. The Company defines the fair value of a financial instrument as the amount that would be received from the sale of an asset in an orderly transaction between market participants at the measurement date. The Company is responsible for the determination of the value of the investment carried and fair value and the supporting methodologies and assumptions. The Company uses various pricing sources to validate the values utilized.
The degree of judgment used in measuring the fair value of financial instruments generally inversely correlates with the level of observable valuation inputs. Financial instruments with quoted prices in active markets generally have more pricing observability and less judgment is used in measuring fair value. Financial instruments for which no quoted prices are available have less observability and are measured at fair value using valuation models or other pricing techniques that require more judgment.
Assets recorded at fair value in the Consolidated Balance Sheets are measured and classified in accordance with a fair value hierarchy consisting of the three “levels” based on the observability of inputs available in the marketplace used to measure the fair values as discussed below:
Investment in marketable securities, available-for-sale and assets held in the Rabbi Trust are carried at fair value based on observable inputs available. All these securities are measured as Levels 1 or 2 as appropriate. The Company has no investments measured as Level 3.
Assets and Liabilities not Measured at Fair Value
The Company’s cash and cash equivalents, commissions receivable, amounts due from employees (included in other assets, net current and other asset non-current captions), 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 and considered to be in the Level 1 classification.
As the Company’s obligations under notes payable to former stockholders bear fixed interest rates that approximate current interest rates for debt instruments with similar terms and maturities, 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 commission’s caption) bear interest at a variable rate based on U.S. Treasuries, the Company has determined that the carrying value approximates the fair value. These are considered to be in the Level 2 classification.
Property and Equipment, Net
Property and equipment are stated at cost less accumulated depreciation and amortization. The Company uses the straight-line method for depreciation and amortization. Depreciation and amortization are provided over estimated useful lives ranging from three to seven years.
The Company evaluates its fixed assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable.
Other assets consist primarily of amounts due from the Company’s investment sales and financing professionals, security deposits made in connection with operating leases, customer trust accounts, employee notes receivable and other receivables.
The Company, from time to time, advances funds to or on behalf of its investment sales and financing professionals. Certain amounts may bear a nominal interest rate, with any cash receipts on notes applied first to any unpaid principal balance prior to any income being recognized. The Company generally has the ability to collect a portion of these amounts from future commissions due to the investment sales and financing professional. The Company may forgive a portion of the amount over time depending on the nature of the advance generally ratably over a contracted service period. Amounts forgiven are charged to cost of services at the time the amounts are forgiven. The Company evaluates the need for an allowance for these amounts based on the specific identification of potentially uncollectible amounts and provides an allowance based on consideration of historical experience. Amounts are written off upon separation from the Company of the investment sales and financing professional as a service provider or when amounts are determined to be no longer collectable.
In connection with a brokerage transaction, the Company may need to, or be required to, hold cash in escrow for a transaction participant. These amount are deposited into separate customer trust accounts controlled by the Company. The amounts are included in current other assets, net with a corresponding liability included in accounts payable and accrued expenses, both in the Consolidated Balance Sheets.
The Company leases all of its facilities under operating lease agreements. Lease agreements may contain periods of free rent or reduced rent or contain predetermined fixed increases in the minimum rent. The Company recognizes the minimum lease payments as rent expense on a straight-line basis over the noncancellable term of the lease. The Company records the difference between the amount charged to rent expense and the rent paid as a deferred rent obligation. The Company typically leases general purpose built-out office space, which reverts to the lessor upon termination of the lease. Any payments for improvements, net of incentives received, are recorded as prepaid rent. Prepaid rent is amortized using the straight-line method over the expected lease term as a charge to rent expense.
Advertising costs are expensed as incurred. Advertising costs are included in selling, general, and administrative expense in the accompanying consolidated statements of net and comprehensive income.
Advertising expense for the years ended December 31, 2015, 2014 and 2013 was $1.1 million, $965,000 and $975,000, respectively.
The Company accounts for income taxes under the asset and liability method. The Company recognizes deferred tax assets and liabilities for the future tax consequences attributable to (1) differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax basis, and (2) operating losses and tax credit carryforwards. The Company measures existing deferred tax assets and liabilities using enacted tax rates expected to apply to taxable income in the years in which the Company expects to have temporary differences to be realized or settled. The Company recognizes into income the effect on deferred tax assets and liabilities of a change in tax rates in the period that includes the enactment date. The Company periodically evaluates the deferred tax assets to assess whether it is likely that the deferred tax assets will be realized. In determining whether a valuation allowance is required, the Company considers the timing of deferred tax reversals, current year taxable income and historical performance. Valuation allowances are provided against deferred tax assets when it is more-likely-than-not that some portion or all of the deferred tax asset will not be realized.
Because of the nature of the Company’s business, which includes activity in the U.S. and Canada, incorporating numerous states and provinces as well as local jurisdictions, the Company’s tax position can be complex. As such, the Company’s effective tax rate is subject to changes as a result of changes in the mix of its activity in the various jurisdictions in which the Company operates including changes in tax rates, state apportionment, tax related interest and penalties, valuation allowances and other permanent items.
The threshold for recognizing the benefits of tax return positions in the financial statements is “more likely than not” to be sustained by the taxing authority and requires measurement of a tax position meeting the more-likely-than-not criterion, based on the largest benefit that is more than 50% likely to be realized. The Company’s inventory of tax positions has been assessed with respect to all applicable income tax issues for all open tax years (in each respective jurisdiction), and has concluded that no uncertain tax positions are required to be recognized in the Company’s consolidated financial statements.
The Company recognizes interest and penalties incurred as income tax expense.
Prior to the IPO, the Company was part of a consolidated federal income tax return and various combined and consolidated state tax returns that were filed by its previous parent. The Company had a tax-sharing agreement whereby the Company provided for income taxes in its consolidated statements of net and comprehensive income using an effective tax rate of 43.5%. In addition, all deferred tax assets and liabilities were recorded by its parent. As part of the Spin-Off, the Company’s tax sharing agreement with its former parent was terminated effective October 31, 2013 and the Company’s allocable net deferred tax assets were transferred to the Company.
The Company follows the accounting guidance for share based payments which requires the measurement and recognition of compensation expense for all stock based awards made to employees, independent contractors and non-employee directors. Awards are issued under the 2013 Omnibus Equity Incentive Plan (the “2013 Plan”) and 2013 Employee Stock Purchase Plan (“2013 ESPP Plan”).
For awards made to the Company’s employees and directors, the Company initially values its restricted stock units and restricted stock awards based on the grant date closing price of the Company’s common stock. For awards with periodic vesting, the Company recognizes the related expense on a straight-line basis over the requisite service period for the entire award, subject to periodic adjustments to ensure that the cumulative amount of expense recognized through the end of any reporting period is at least equal to the portion of the grant date value of the award that has vested through that date.
For awards made to independent contractors, which are the Company’s investment sales and financing professionals, the Company determined that the fair value of the award shall be measured based on the fair value of the equity instrument as it is more reliably measureable than the fair value of the consideration received. The Company uses the grant date as the performance commitment date, and the measurement date for these awards is the date the services are completed, which is the vesting date. As a result, the Company records stock-based compensation for these awards over the vesting period on a straight-line basis with periodic adjustments during the vesting period for changes in the fair value of the awards.
For the above awards, the Company estimates forfeitures at the time of grant in order to estimate the amount of share-based payment awards ultimately expected to vest and adjusts the recorded expense accordingly. The Company calculates a separate forfeiture rate for awards to its employees and independent contractors. Forfeitures are required to be revised, if necessary, in subsequent periods. If estimated and actual forfeitures differ from these initial estimates, the Company adjusts the cumulative expense as appropriate to account for the change in the estimated forfeiture rates. If there are any modifications or cancellations of the underlying unvested share-based awards, the Company may be required to accelerate, increase or cancel any remaining unrecognized stock-based compensation expense. Stock-based compensation expense is included in general and administrative expense in the accompanying consolidated statements of net and comprehensive income.
For awards issued under the 2013 ESPP Plan, the Company determined that the plan was a compensatory plan and is required to expense the fair value of the awards over each six-month offering period. The Company estimates the fair value of these awards using the Black-Scholes option pricing model. The Company calculates 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 Company incorporates no forfeiture rate and includes no expected dividend yield as the Company has not, and currently does not intend to pay a regular dividend. See Note 9 – “Stockholders’ Equity” for additional information on dividends.
Stock-Based Compensation Prior to the IPO
MMREIS historically issued stock options and stock appreciation rights, or SARs, to key employees through a book value, stock-based compensation award program (the “Program”). The Program allowed for employees to exercise stock options in exchange for shares of unvested restricted common stock. The Program also allowed employees to exercise options through the issuance of notes receivable, which were recourse to the employee. The determination of the grant price and repurchase price of stock-based awards at the grant date and repurchase date were fixed as determined by a valuation formula using book value, as defined by the agreements between MMREIS and the employees. The stock awards generally vested over a three to five-year period. Under these plans, MMREIS retained the right to repurchase shares if certain events occurred, which included termination of employment. In these circumstances, the plan document provided for repurchase proceeds to be settled in the form of a note payable to (former) shareholders or cash, which was settled over a fixed period. While MMREIS had entered into the agreements to repurchase the stock and settle the SARs held by employees upon termination of their employment (subject to certain conditions as specified in the agreements), MMC had historically assumed the obligation to make payments to the former shareholders. While MMREIS recognized the compensation expense associated with these share-based payment arrangements, the liability had historically been assumed by MMC through a deemed contribution, which then has paid the former shareholders over time. The accounting for the stock options and SARs awards, including MMC’s assumption of MMREIS repurchase obligations, is discussed below.
Restricted Common Stock
Since stock options only allowed the grantee the right to acquire shares of unvested restricted common stock at book value, which was determined on an annual basis, MMREIS accounted for the stock options and the related unvested restricted stock, as a single instrument, with a single service period. The service period began on the option grant date, and extended through the exercise and subsequent vesting period of the restricted stock. The unvested restricted common stock was accounted for in accordance with ASC 718. Increases or decreases in the formula settlement value of unvested restricted stock subsequent to the grant date, were recorded as increases or decreases, respectively, to compensation expense, with decreases limited to the book value of the stock on the date of grant. As MMC had assumed the Company’s obligation with respect to any appreciation in the value of the underlying vested awards in excess of the employees’ exercise price, MMC was deemed to make a capital contribution to the Company’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 the Company and MMC, the tax deduction for the compensation expense recorded by the Company was allocated to MMC. MMC recorded the liability related to the appreciation in the value of the underlying stock in its consolidated financial statements. To the extent of any depreciation in the value of the underlying vested awards (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.
SARs granted to employees were accounted for in accordance with ASC 718. Compensation expense related to the SARs was recorded in each period and was equal to the appreciation in the formula-settlement value of vested SARs at the end of each reporting period-end from the prior reporting period-end. As MMC had assumed the Company’s obligation with respect to any appreciation in the value of the vested SARs, MMC was deemed to make a capital contribution to the Company’s additional paid-in capital equal to the amount of compensation expense recorded, net of the applicable taxes. Based on the tax-sharing agreement entered between the Company and MMC, the tax deduction for the compensation expense recorded by the Company was allocated to MMC. MMC recorded the liability related to the appreciation in the value of the underlying stock in its consolidated financial statements. To the extent of any depreciation in the value of the vested SARs (limited to the amount of any appreciation previously recorded), compensation expense was reduced and MMC was deemed to have received a capital distribution.
Earnings per Share
Earnings per share is calculated using net income attributable to Marcus & Millichap, Inc. subsequent to the IPO on October 31, 2013. Earnings per share prior to the IPO has not been presented as the holders of MMREIS Series A Redeemable Preferred Stock were entitled to receive discretionary dividends, payable in preference and priority to any distribution on MMREIS common stock. Since MMREIS typically distributed its earnings to the Series A Preferred stockholders on a quarter-in-arrears basis, earnings per share information for MMREIS common stock prior to the IPO was not meaningful.
Basic weighted average shares outstanding includes vested, but un-issued, Deferred Stock Units (“DSU’s). The difference between basic and diluted weighted average shares outstanding represents the dilutive impact of common stock equivalents consisting of shares to be issued under the 2013 Plan and 2013 ESPP Plan.
Foreign Currency Translation
The Company prepares the financial statements of its Canadian subsidiary using the local currency as the functional currency. The assets and liabilities of the Company’s Canadian subsidiary are translated in to U.S. dollars at the rates of exchange at the balance sheet date with the resulting translation adjustments included as a separate component of stockholder’s equity through other comprehensive income (loss) in the consolidated statements of net and comprehensive income.
Income and expenses are translated at the average monthly rates of exchange. The Company includes gains and losses from foreign currency transactions in other income (expense), net in the consolidated statements of net and comprehensive income.
The effect of foreign currency translation on cash and cash equivalent is reflected in cash flows from operating activities on the consolidated statements of cash flows, and is not material for any period presented.
Taxes Collected From Clients and Remitted to Governmental Authorities
The Company accounts for tax assessed by any governmental authority that is based on revenue or transaction value (i.e. sales, use and value added taxes) on a net basis, and, accordingly, such amounts are not included in revenue. Collected amounts are recorded as a current liability until paid.
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 periods. Actual results could differ from those estimates.
Concentration of Credit Risk
Financial instruments that potentially subject the Company to a concentration of credit risk principally consist of cash and cash equivalents, due from independent contractors, investments in marketable securities, available-for-sale, security deposits (included under other assets, non-current caption) and commissions receivables. Cash is placed with high-credit quality financial institutions and invested high-credit quality money market funds.
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 related to cash and cash equivalents. The Company derives its revenues from a broad range of real estate investors, owners, and users in the United States and Canada, none of which individually represents a significant concentration of credit risk. The Company performs ongoing credit evaluations of its customers and debtors and requires collateral on a case-by-case basis. The Company maintains allowances, as needed, for estimated credit losses based on management’s assessment of the likelihood of collection. For the twelve months ended December 31, 2015 and 2014, no transaction represented 10% or more of total revenues. Further, while one or more transactions may represent 10% or more of commissions receivable at any reporting date, amounts due are typically collected within 10 days of settlement and therefore do not expose the Company to significant credit risk.
The Company follows the guidance for segment reporting, which requires reporting information on operating segments in interim and annual financial statements. An operating segment is defined as a component of an enterprise that engages in business activities from which it may earn revenues and incur expenses whose separate financial information is available and is evaluated regularly by the Chief Operating Decision Maker (“CODM”) or decision making group, to perform resource allocations and performance assessments. The CODMs are the Chief Executive Officer, Senior Executive Vice President and Chief Financial Officer. The CODMs review financial information presented on an office-by-office basis for purposes of making operating decisions, assessing financial performance and allocating resources. Based on the evaluation of the Company’s financial information, management believes that the Company’s offices represent individual operating segments with similar economic characteristics that meet the criteria for aggregation into a single reportable segment for financial reporting purposes. The Company’s financing operations may represent an individual operating segment; however, it does not meet the thresholds to be presented as a separate reportable segment.
Recent Accounting Pronouncements
In 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 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. Following FASB’s finalization of a one year deferral of ASU 2014-09, the ASU is now 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 does not have multiple-element arrangements, variable consideration, licenses and long-term contracts with customers. Accordingly, the Company does not expect this standard to have a significant effect on its revenue recognition. The Company is currently evaluating the impact of this new standard and will select a transition method when the effect is determined.
In August 2014, the FASB issued ASU 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. The Company does not anticipate that the adoption will have an impact on the Company’s consolidated financial position or results of operations.
In April 2015, the FASB issued ASU 2015-03, Interest – Imputation of Interest: Simplifying the Presentation of Debt Issuance Costs (“ASU 2015-03”), which requires debt issuance costs to be presented in the balance sheet as a direct deduction from the associated debt liability. ASU 2015-03 does not change the amortization of debt issuance costs, which continues to follow the existing accounting guidance. In August 2015, the FASB issued ASU 2015-15, Presentation and Subsequent Measurement of Debt Issuance Costs Associated with Line-of-Credit Arrangements (“ASU 2015-15”), which codified the SEC’s comments that the “SEC staff would not object to an entity deferring and presenting debt issuance costs as an asset and subsequently amortizing the deferred debt issuance costs ratably over the term of the line-of-credit arrangement, regardless of whether there are any outstanding borrowings on the line-of-credit arrangement”. ASU 2015-03 and ASU 2015-15 are effective for interim and annual reporting periods beginning after December 15, 2015 and early adoption is permitted. The Company early adopted ASU 2015-03 and ASU 2015-15 during the quarter ended September 30, 2015. The adoption of ASU 2015-03 and ASU 2015-15, did not have any impact on the Company’s consolidated financial position or results of operations.
In November 2015, the FASB issued ASU 2015-17, Balance Sheet Classification of Deferred Taxes (“ASU 2015-17”). The ASU 2015-17 is intended to simplify the presentation of deferred income taxes, which eliminated the requirement to classify deferred income taxes as current and non-current in a classified statement of financial position. ASU 2015-17 applies to all entities that present a classified statement of financial position. The Company elected to early adopt the provisions of ASU 2015-17 effective October 1, 2015. The Company has chosen to retrospectively apply the provisions of ASU 2015-17 and as a result, the Company reclassified current deferred taxes of $13.6 million to non-current deferred taxes in the accompanying consolidated balance sheet as of December 31, 2014 and revised related footnote disclosure to reflect the new classification.
On February 25, 2016, the FASB issued ASU 2016-02, Leases, to increase transparency and comparability by recognizing lase assets and lease liabilities on the balance sheet and disclosing key information about leasing arrangements. The Company is still evaluating the impact of the new standard. It is anticipated that the Company will be required to adopt the new standard in 2019 and the Company’s consolidated balance sheets will be impacted by the recording of a lease liability and right of use asset for virtually all of its current operating leases, the amount of which and potential impact on the consolidated statements of net and comprehensive income and consolidated statements of cash flows has yet to be determined. Since the Company has future operating lease obligations for autos and office spaces which aggregates approximately $79.8 million (see – Note 14 – “Commitments and Contingencies” for additional information), it is anticipated that the adoption of the new standard will have a material impact on the Company’s consolidated balance sheet.
