(1) Business organization

Planet Fitness, Inc. (the “Company”), through its subsidiaries, is a franchisor and operator of fitness centers, with approximately 7.3 million members and 1,124 owned and franchised locations (referred to as stores) in 47 states, the District of Columbia, Puerto Rico, Dominican Republic and Canada as of December 31, 2015.

The Company serves as the reporting entity for its various subsidiaries that operate three distinct lines of business:

In 2012 investment funds affiliated with TSG Consumer Partners, LLC (“TSG”), purchased interests in Pla-Fit Holdings.

The Company was formed as a Delaware corporation on March 16, 2015 for the purpose of facilitating an initial public offering (the “IPO”) and related transactions in order to carry on the business of Pla-Fit Holdings, LLC and its subsidiaries (“Pla-Fit Holdings”). As of August 5, 2015, in connection with the recapitalization transactions discussed below, the Company became the sole managing member and holder of 100% of the voting power and 37.1% of the economic interest of Pla-Fit Holdings. Pla-Fit Holdings owns 100% of Planet Intermediate, LLC which has no operations but is the 100% owner of Planet Fitness Holdings, LLC, a franchisor and operator of fitness centers. With respect to the Company, Pla-Fit Holdings and Planet Intermediate, LLC, each entity owns nothing other than the respective entity below it in the corporate structure and each entity has no other material operations.

Initial Public Offering

On August 11, 2015, the Company completed an IPO pursuant to which the Company and selling stockholders sold an aggregate of 15,525,000 shares of Class A common stock at a public offering price of $16.00 per share. The Company received $156,946 in proceeds from its sale of 10,491,055 shares of Class A common stock, net of underwriting discounts and commissions, which were used to purchase an equal number of limited liability company units (“Holdings Units”) from existing holders (“Continuing LLC Owners”) of interests in Pla-Fit Holdings, at a purchase price per unit equal to the IPO price per share of Class A common stock, net of underwriting discounts and commissions. 

Recapitalization Transactions

In connection with the IPO, the Company and Pla-Fit Holdings completed a series of recapitalization transactions on August 5, 2015 which are described below (also see Note 12):

Subsequent to the IPO and the related recapitalization transactions, the Company is a holding company whose principal asset is a controlling equity interest in Pla-Fit Holdings. As the sole managing member of Pla-Fit Holdings, the Company operates and controls all of the business and affairs of Pla-Fit Holdings, and through Pla-Fit Holdings, conducts its business. As a result, the Company consolidates Pla-Fit Holdings’ financial results and reports a non-controlling interest related to the portion of Holdings Units not owned by the Company. As of December 31, 2015, the Company held 100% of the voting interest, and approximately 37.1% of the economic interest in Pla-Fit Holdings. As future exchanges of Holdings Units occur, the economic interest in Pla-Fit Holdings held by Planet Fitness, Inc. will increase.

The recapitalization transactions are considered transactions between entities under common control.  As a result, the financial statements for periods prior to the IPO and the recapitalization transactions are the financial statements of Pla-Fit Holdings as the predecessor to the Company for accounting and reporting purposes.  Unless otherwise specified, “the Company” refers to both Planet Fitness, Inc. and Pla-Fit Holdings throughout the remainder of these notes.

(2) Summary of significant accounting policies

(a) Basis of presentation and consolidation

The accompanying consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (U.S. GAAP) and pursuant to the rules and regulations of the Securities and Exchange Commission (the “SEC”). All significant intercompany balances and transactions have been eliminated in consolidation.

As discussed in Note 1, as a result of the recapitalization transactions, Planet Fitness, Inc. consolidates Pla-Fit Holdings and Pla-Fit Holdings is considered to be the predecessor to Planet Fitness, Inc. for accounting and reporting purposes. The Company also consolidates entities in which it has a controlling financial interest, the usual condition of which is ownership of a majority voting interest. The Company also considers for consolidation certain interests where the controlling financial interest may be achieved through arrangements that do not involve voting interests. Such an entity, known as a variable interest entity (“VIE”), is required to be consolidated by its primary beneficiary. The primary beneficiary of a VIE is considered to possess the power to direct the activities of the VIE that most significantly impact its economic performance and has the obligation to absorb losses or the rights to receive benefits from the VIE that are significant to it. The principal entities in which the Company possesses a variable interest include franchise entities and certain other entities. The Company is not deemed to be the primary beneficiary for Planet Fitness franchise entities. Therefore, these entities are not consolidated.

The results of the Company have been consolidated with Matthew Michael Realty LLC (“MMR”) and PF Melville LLC (“PF Melville”) based on the determination that the Company is the primary beneficiary with respect to these VIEs. These entities are real estate holding companies that derive a majority of their financial support from the Company through lease agreements for corporate stores. See Note 3 for further information related to the Company’s VIEs.

(b) Use of estimates

The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Although these estimates are based on management’s knowledge of current events and actions it may undertake in the future, they may ultimately differ from actual results. Significant areas where estimates and judgments are relied upon by management in the preparation of the consolidated financial statements include revenue recognition, valuation of assets and liabilities in connection with acquisitions, valuation of equity-based compensation awards, the evaluation of the recoverability of goodwill and long-lived assets, including intangible assets, income taxes, including deferred tax assets and liabilities and reserves for unrecognized tax benefits, and the liability for the Company’s tax benefit arrangements.

(c) Concentrations

Cash and cash equivalents are financial instruments, which potentially subject the Company to a concentration of credit risk. The Company invests its excess cash in several major financial institutions, which are insured by the Federal Deposit Insurance Corporation (FDIC) up to $250,000. The Company maintains balances in excess of these limits, but does not believe that such deposits with its banks are subject to any unusual risk.

The credit risk associated with trade receivables is mitigated due to the large number of customers, generally our franchisees, and their broad dispersion over many different geographic areas. We do not have any concentrations with respect to our revenues.

The Company purchases equipment, both for corporate-owned stores and for sales to franchisee-owned stores, from two primary vendors. For the year ended December 31, 2015 purchases from these two vendors comprised 79% and 18%, respectively, for the year ended December 31, 2014 purchases from these two vendors comprised 66% and 25%, respectively, and for the year ended December 31, 2013 purchases from these two vendors comprised 66% and 27%, respectively, of total equipment purchases.

The Company, including Planet Fitness NAF, LLC (“NAF”) uses one primary vendor for advertising services. Purchases from this vendor totaled 49%, 61%, and 68% of total advertising purchases for the years ended December 31, 2015, 2014 and 2013, respectively (see Note 5 for further discussion of NAF).

(d) Cash and cash equivalents

The Company considers all highly liquid investments purchased with an original maturity of 90 days or less to be cash equivalents. Cash held within the NAF is recorded as a restricted asset (see Note 5).

(e) Revenue recognition

Franchise revenue

The following revenues are generated as a result of transactions with or related to the Company’s franchisees.

Area development fees

Franchisees contractually enter into area development agreements (ADAs) to secure the exclusive right to open franchise stores within a defined geographical area. ADAs establish the timing and number of stores to be developed within the defined geographical area. Pursuant to an ADA, a franchisee is generally required to pay an initial nonrefundable development fee for a minimum number of stores to be developed, as outlined in the respective ADA. ADA fees collected in advance are deferred until the Company provides substantially all required obligations pursuant to the ADA. As the efforts and total cost relating to initial services are affected significantly by the number of stores opened in an area, the respective ADA is treated as a divisible contract. As each new site is accepted under an ADA, a franchisee signs a franchise operating agreement for the respective franchise location. As each store opened under an ADA typically has performance obligations associated with it, the Company recognizes ADA revenue as each individual franchise location is developed in proportion to the total number of stores to be developed under the ADA. These obligations are typically completed once the store is opened or the franchisee executes the individual property lease. As of December 31, 2015 and 2014, the deferred revenue for ADAs was $10,471 and $8,215, respectively. ADAs generally have an initial term equal to the number of years over which the franchisee is required to open franchise stores, which is typically 5 to 10 years. There is no right of refund for an executed ADA. Upon default, as defined in the agreement, the Company may reacquire the rights pursuant to an ADA, and all remaining deferred revenue is recognized at that time.

Franchise fees and performance fees

For stores opened without an ADA, the Company generally charges an initial upfront nonrefundable franchise fee. Nonrefundable franchise fees are typically deferred until the franchisee executes a lease and receives initial training for the location, which is the point at which the Company has determined it has provided all of its material obligations required to recognize revenue. As of December 31, 2015 and 2014, the Company has recorded deferred franchise fees of $473 and $205, respectively, relating to stores to be opened in future years. These amounts are included in deferred revenue as of December 31, 2015 and 2014.

The individual franchise agreements typically have a 10-year initial term, but provide the franchisee with an opportunity to enter into successive renewals subject to certain conditions.

Franchise agreements entered into prior to 2010 may include performance fees, which are fees earned by the Company upon each franchise store reaching a predetermined amount of total monthly membership billings. Performance fees are recognized when the related performance thresholds have been met.

Royalties

Royalties, which represent recurring fees paid by franchisees based on the franchisee-owned stores’ monthly membership billings, are recognized on a monthly basis over the term of the franchise agreement. As specified under certain franchise agreements, the Company recognizes additional royalty fees as the franchisee-owned stores attain contractual monthly membership billing threshold amounts. Beginning in 2010, for all new franchise agreements entered into, the Company began charging a fixed royalty percentage based upon gross membership billings.

Other fees

Online member join fees are paid to the Company by franchisees for processing new membership transactions when a new member signs up for a membership to a franchisee-owned store through the Company’s website.

Billing transaction fees are paid to the Company for the processing of franchisee membership dues and annual fees through the Company’s third-party hosted point-of-sale system.

Placement

The Company is generally responsible for assembly and placement of equipment it sells to franchisee-owned stores. Placements revenue is recognized upon completion and acceptance of the services at the franchise location.

Commission income

The Company recognizes commission income from its franchisees’ use of preferred vendor arrangements. Commissions are recognized when amounts have been earned and collectability from the vendor is reasonably assured.

Corporate-owned stores revenue

The following revenues are generated from stores owned and operated by the Company.

Membership dues revenue

Customers are offered multiple membership choices varying in length. Membership dues are earned and recognized over the membership term on a straight-line basis.

Enrollment fee revenue

Enrollment fees are charged to new members at the commencement of their membership. The Company recognizes enrollment fees ratably over the estimated duration of the membership life, which is generally two years.

Annual membership fee revenue

Annual membership fees are annual fees charged to members in addition to and in order to maintain low monthly membership dues. The Company recognizes annual membership fees ratably over the 12-month membership period.

Retail sales

The Company sells Planet Fitness branded apparel, food, beverages, and other accessories. The revenue for these items is recognized at the point of sale.

Equipment revenue

The Company sells and delivers equipment purchased from third-party equipment manufacturers to U.S. based franchisee-owned stores. Equipment revenue is recognized upon the equipment being delivered to and assembled at each store and accepted by the franchisee. Franchisees are charged for all freight costs incurred for the delivery of equipment. Freight revenue is recorded within equipment revenue and freight costs are recorded within cost of revenue. The Company recognizes revenue on a gross basis in these transactions as management has determined the Company to be the principal in these transactions. Management determined the Company to be the principal because the Company is the primary obligor in these transactions, the Company has latitude in establishing prices for the equipment sales to franchisees, the Company has supplier selection discretion and is involved in determination of product specifications, and the Company bears all credit risk associated with obligations to the equipment manufacturers.

Equipment deposits are recognized as a liability on the accompanying consolidated balance sheets until delivery, assembly (if required), and acceptance by the franchisee. As of December 31, 2015 and 2014, equipment deposits were $5,587 and $6,675, respectively.

Sales tax

All revenue amounts are recorded net of applicable sales tax.

(f) Deferred revenue

Deferred revenue represents cash received from franchisees for ADAs and franchise fees for which revenue recognition criteria has not yet been met and cash received from members for enrollment fees, membership dues and annual fees for the portion not yet earned based on the membership period.

(g) Cost of revenue

Cost of revenue consists of direct costs associated with equipment sales, including freight costs, direct costs related to the maintenance and support of the Company’s proprietary system-wide point-of-sale system, and the cost of retail merchandise sold in corporate-owned stores. Costs related to the point-of-sale system were $1,236, $3,385, and $1,107 for the years ended December 31, 2015, 2014 and 2013 respectively. Costs related to retail merchandise were immaterial in all periods presented. Rebates from equipment vendors where the Company has recognized the related equipment revenue and costs are recorded as a reduction to the cost of revenue.

(h) Store operations

Store operations consists of the direct costs related to operating corporate-owned stores, including our store management and staff, rent expense, utilities, supplies, maintenance, and local advertising.

(i) Selling, general and administrative

Selling, general and administrative expenses consist of costs associated with administrative and franchisee support functions related to our existing business as well as growth and development activities. These costs primarily consist of payroll, IT related, marketing, legal and accounting expenses. These expenses include costs related to placement services of $3,452, $2,743, and $2,245, for the years ended December 31, 2015, 2014 and 2013, respectively.

(j) Accounts and notes receivable

Accounts receivable is primarily comprised of amounts owed to the Company resulting from equipment, placement, and commission revenue. Notes receivable arise primarily from financing activities with franchisees. The Company evaluates its accounts and notes receivable on an ongoing basis and may establish an allowance for doubtful accounts based on collections and current credit conditions. Accounts are written off as uncollectible when it is determined that further collection efforts will be unsuccessful. Notes receivable are generally secured by all property, assets, and rights owned by the franchisee. Historically, the Company has not had a significant amount of write-offs.

(k) Leases and asset retirement obligations

The Company recognizes rent expense related to leased office and operating space on a straight-line basis over the term of the lease. The difference between rent expense and rent paid, if any, as a result of escalation provisions and lease incentives, such as tenant improvements provided by lessors, and is recorded as deferred rent in the Company’s consolidated balance sheets.

In accordance with ASC Topic 410, Asset Retirement and Environmental Obligations, the Company establishes assets and liabilities for the present value of estimated future costs to return certain leased facilities to their original condition. Such assets are depreciated on a straight-line basis over the lease period into operating expense, and the recorded liabilities are accreted to the future value of the estimated restoration costs.

(l) Property and equipment

Property and equipment is recorded at cost and depreciated using the straight-line method over its related estimated useful life. Leasehold improvements are amortized over the shorter of the lease term or the estimated useful life of the related asset, whichever is shorter. Upon sale or retirement, the asset cost and related accumulated depreciation are removed from the respective accounts, and any related gain or loss is reflected in the consolidated statements of operations. Ordinary maintenance and repair costs are expensed as incurred. The estimated useful lives of the Company’s fixed assets by class of asset are as follows:

(m) Advertising expenses

The Company expenses advertising costs as incurred. Advertising expenses, net of amounts reimbursed by franchisees, are included within selling, general and administrative expenses and totaled $9,349, $7,272, and $5,731 for the years ended December 31, 2015, 2014 and 2013, respectively. See Note 5 for discussion of the national advertising fund.

(n) Goodwill, long-lived assets, and other intangible assets

Goodwill and other intangible assets that arise from acquisitions are recorded in accordance with ASC Topic 350, Intangibles—Goodwill and Other. In accordance with this guidance, specifically identified intangible assets must be recorded as a separate asset from goodwill if either of the following two criteria is met: (1) the intangible asset acquired arises from contractual or other legal rights; or (2) the intangible asset is separable. Intangibles are typically trade and brand names, customer relationships, noncompete agreements, reacquired franchise rights, and favorable or unfavorable leases. Transactions are evaluated to determine whether any gain or loss on reacquired franchise rights, based on their fair value, should be recognized separately from identified intangibles. Goodwill is the excess of the purchase price over the fair value of identifiable net assets acquired in a business combination.

Goodwill and indefinite-lived intangible assets are not amortized, but are reviewed annually for impairment or more frequently if impairment indicators arise. Separable intangible assets that are not deemed to have an indefinite life are amortized over their estimated useful lives on either a straight-line or accelerated basis as deemed appropriate, and are reviewed for impairment when events or circumstances suggest that the assets may not be recoverable.

The Company performs its annual test for impairment of goodwill and indefinite lived intangible assets on December 31 of each year. For goodwill, the first step of the impairment test is to determine whether the carrying amount of a reporting unit exceeds the fair value of the reporting unit. If the carrying amount of the reporting unit exceeds the reporting unit’s fair value, the Company would be required to perform a second step of the impairment test as this is an indication that the reporting unit’s goodwill may be impaired. The second step compares the implied fair value of the reporting unit’s goodwill with the carrying amount of that goodwill. Any impairment loss would be recognized in an amount equal to the excess of the carrying value of the goodwill over the implied fair value of the goodwill. The Company is also permitted to make a qualitative assessment of whether it is more likely than not that a reporting unit’s fair value is less than its carrying amount before applying the two-step goodwill impairment test. If the Company concludes it is not more likely than not that the fair value of a reporting unit is less than its carrying amount, it need not perform the two-step impairment test.

For indefinite lived intangible assets, the impairment assessment consists of comparing the carrying value of the asset to its estimated fair value. To the extent that the carrying value exceeds the fair value of the asset, an impairment is recorded to reduce the carrying value to its fair value. The Company is also permitted to make a qualitative assessment of whether it is more likely than not an indefinite lived intangible asset’s fair value is less than its carrying value prior to applying the quantitative assessment. If based on the Company’s qualitative assessment it is not more likely than not that the carrying value of the asset is less than its fair value, then a quantitative assessment is not required.

The Company determined that no impairment charges were required during any periods presented.

The Company applies the provisions of ASC Topic 360, Property, Plant and Equipment, which requires that long-lived assets, including amortizable intangible assets, be reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. If circumstances require a long-lived asset or asset group to be tested for impairment, then assets are required to be grouped and evaluated at the lowest level for which there are identifiable cash flows that are largely independent of the cash flows of other groups of assets. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset or asset group to the undiscounted future net cash flows expected to be generated by the asset or asset group. If such assets are considered to be impaired, the impairment to be recognized is measured by the amount by which the carrying amount of the assets exceeds the fair value of the assets. Assets to be disposed of are reported at the lower of the carrying amount or fair value less costs to sell. There were no events or changes in circumstances that required the Company to test for impairment during any of the periods presented.

(o) Income taxes

The Company accounts for income taxes using the asset and liability method. Deferred income taxes are recognized for the expected future tax consequences attributable to temporary differences between the carrying amount of the existing tax assets and liabilities and their respective tax basis. Deferred tax assets and liabilities are measured using enacted tax rates expected to be applied in the years in which temporary differences are expected to be recovered or settled. The principal items giving rise to temporary differences are the use of accelerated depreciation and certain basis differences resulting from acquisitions and the recapitalization transactions. Valuation allowances are established when necessary to reduce deferred tax assets to the amount expected to be realized.

As a result of the recapitalization transactions, Planet Fitness, Inc. became the sole managing member of Pla-Fit Holdings, which is treated as a partnership for U.S. federal and most applicable state and local income tax purposes. As a partnership, Pla-Fit Holdings is not subject to U.S. federal and certain state and local income taxes. Any taxable income or loss generated by Pla-Fit Holdings is passed through to and included in the taxable income or loss of its members, including Planet Fitness, Inc. following the recapitalization transactions, on a pro rata basis. Planet Fitness, Inc. is subject to U.S. federal income taxes, in addition to state and local income taxes with respect to our allocable share of any taxable income of Pla-Fit Holdings following the recapitalization transactions. The Company is also subject to taxes in foreign jurisdictions.

The Company recognizes the effect of income tax positions only if those positions are more likely than not to be sustained. Recognized income tax positions are measured at the largest amount that is greater than 50% likely of being realized. Changes in recognition or measurement are reflected in the period in which the change in judgment occurs (see Note 16).

During 2013 the Company changed its position with respect to taxes due on interest and dividends to the state of New Hampshire that had previously been paid by the members. This resulted in the Company making tax payments in 2013 totaling $4,392 for periods prior to November 7, 2012. This amount is included within other income (expense) for the year ended December 31, 2013 and is fully offset by amounts received from the members as reimbursement for the taxes paid, also recorded within other income (expense) for the year ended December 31, 2013. This position is not available for periods subsequent to November 7, 2012 and therefore taxes on interest and dividends due and payable in the periods after 2012 are paid by the members of Pla-Fit Holdings.

(p) Tax benefit arrangements

The Company’s acquisition of Holdings Units in connection with the IPO and future and certain past exchanges of Holdings Units for shares of the Company’s Class A common stock (or cash at the option of the Company) are expected to produce and have produced favorable tax attributes. In connection with the IPO, the Company entered into two tax receivable agreements. Under the first of those agreements, the Company generally is required to pay to the Continuing LLC Owners 85% of the applicable tax savings, if any, in U.S. federal and state income tax that the Company is deemed to realize as a result of certain tax attributes of their Holdings Units sold to the Company (or exchanged in a taxable sale) and that are created as a result of (i) the sales of their Holdings Units for shares of Class A common stock and (ii) tax benefits attributable to payments made under the tax receivable agreement (including imputed interest). Under the second tax receivable agreement, the Company generally is required to pay to the Direct TSG Investors 85% of the amount of tax savings, if any, that the Company is deemed to realize as a result of the tax attributes of the Holdings Units held in respect of the Direct TSG Investors’ interest in the Company, which resulted from the Direct TSG Investors’ purchase of interests in Pla-Fit Holdings in 2012, and certain other tax benefits. Under both agreements, the Company generally retains the benefit of the remaining 15% of the applicable tax savings. Also, pursuant to the exchange agreement, to the extent an exchange results in Pla-Fit Holdings, LLC incurring a current tax liability relating to the New Hampshire business profits tax, the Continuing LLC Owners have agreed that they will contribute to Pla-Fit Holdings, LLC an amount sufficient to pay such tax liability (up to 3.5% of the value received upon exchange). If and when the Company subsequently realizes a related tax benefit, Pla-Fit Holdings, LLC will distribute the amount of any such tax benefit to the relevant Continuing LLC Owner in respect of its contribution.

Based on current projections, the Company anticipates having sufficient taxable income to utilize these tax attributes and receive corresponding tax deductions in future periods. Accordingly, at the completion of the Reorganization Transactions and the IPO, the Company has recorded an initial liability of $142.0 million payable to the Direct TSG Investors and the Continuing LLC Owners under the tax benefit obligations, representing approximately 85% of the calculated tax savings based on the original basis adjustments the Company anticipates being able to utilize in future years. Changes in the projected liability resulting from these tax benefit arrangements may occur based on changes in anticipated future taxable income, changes in applicable tax rates or other changes in tax attributes that may occur and impact the expected future tax benefits to be received by the Company. Changes in the projected liability under these tax benefit arrangements will be recorded as a component of other income (expense) each period. The projection of future taxable income involves significant judgment. Actual taxable income may differ from estimates, which could significantly impact the liability under the tax benefit arrangements and the Company’s consolidated results of operations.  

(q) Fair value

ASC 820, Fair Value Measurements and Disclosures, establishes a three-level valuation hierarchy for disclosure of fair value measurements. The valuation hierarchy is based upon the transparency of inputs to the valuation of an asset or liability as of the measurement date. Categorization within the valuation hierarchy is based upon the lowest level of input that is significant to the fair value measurement. The three levels are defined as follows:

Level 1—Inputs to the valuation methodology are quoted prices (unadjusted) for identical assets or liabilities in active markets.

Level 2—Inputs to the valuation methodology include quoted prices for similar assets and liabilities in active markets, and inputs that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the financial instrument.

Level 3—Inputs to the valuation methodology are unobservable and significant to the fair value measurement.

The table below presents information about the Company’s assets and liabilities that are measured at fair value on a recurring basis as of December 31, 2015 and December 31, 2014:

(r) Financial instruments

The carrying values of cash and cash equivalents, accounts receivable and accounts payable approximate fair value because of the short-term nature of these instruments. The carrying value of debt also approximates fair value as it is variable rate debt. The Company has determined that the determination of fair value of amounts due from related parties under long-term arrangements is impracticable given the related-party nature of these agreements.

(s) Derivative instruments and hedging activities

The Company recognizes all derivative instruments as either assets or liabilities in the balance sheet at their respective fair values. For derivatives designated in hedging relationships, changes in the fair value are either offset through earnings against the change in fair value of the hedged item attributable to the risk being hedged or recognized in accumulated other comprehensive income, to the extent the derivative is effective at offsetting the changes in cash flows being hedged until the hedged item affects earnings.

The Company only enters into derivative contracts that it intends to designate as a hedge of a forecasted transaction or the variability of cash flows to be received or paid related to a recognized asset or liability (cash flow hedge). For all hedging relationships, the Company formally documents the hedging relationship and its risk-management objective and strategy for undertaking the hedge, the hedging instrument, the hedged transaction, the nature of the risk being hedged, how the hedging instrument’s effectiveness in offsetting the hedged risk will be assessed prospectively and retrospectively, and a description of the method used to measure ineffectiveness. The Company also formally assesses, both at the inception of the hedging relationship and on an ongoing basis, whether the derivatives that are used in hedging relationships are highly effective in offsetting changes in cash flows of hedged transactions. For derivative instruments that are designated and qualify as part of a cash flow hedging relationship, the effective portion of the gain or loss on the derivative is reported as a component of other comprehensive income and reclassified into earnings in the same period or periods during which the hedged transaction affects earnings. Gains and losses on the derivative representing either hedge ineffectiveness or hedge components excluded from the assessment of effectiveness are recognized in current earnings.

The Company discontinues hedge accounting prospectively when it determines that the derivative is no longer effective in offsetting cash flows attributable to the hedged risk, the derivative expires or is sold, terminated, or exercised, the cash flow hedge is de-designated because a forecasted transaction is not probable of occurring, or management determines to remove the designation of the cash flow hedge.

In all situations in which hedge accounting is discontinued and the derivative remains outstanding, the Company continues to carry the derivative at its fair value on the balance sheet and recognizes any subsequent changes in its fair value in earnings. When it is probable that a forecasted transaction will not occur, the Company discontinues hedge accounting and recognizes immediately in earnings gains and losses that were accumulated in other comprehensive income related to the hedging relationship. See Note 10 for further information.

(t) Equity-based compensation

The Company has an equity-based compensation plan under which it receives services from employees as consideration for equity instruments of the Company. The compensation expense is determined based on the fair value of the award as of the grant date. Compensation expense is recognized over the vesting period, which is the period over which all of the specified vesting conditions are satisfied. For awards with graded vesting, the fair value of each tranche is recognized over its respective vesting period. See Note 14 for further information.

(u) Guarantees

The Company, as a guarantor, is required to recognize, at inception of the guaranty, a liability for the fair value of the obligation undertaken in issuing the guarantee. See Notes 3 and 17 for further discussion of such obligations guaranteed.

(v) Contingencies

The Company records estimated future losses related to contingencies when such amounts are probable and estimable. The Company includes estimated legal fees related to such contingencies as part of the accrual for estimated future losses.

(w) Reclassifications

Certain amounts have been reclassified to conform to current year presentation, including deferred financing costs, which were previously classified in other assets, net and are now classified as a direct reduction of long-term debt, see Note 2(w).

(x) Recent accounting pronouncements

The FASB issued ASU No. 2015-03, Simplifying the Presentation of Debt Issuance Costs, in April 2015. This guidance requires reporting entities to present debt issuance costs as a direct deduction from the carrying amount of the related debt liability. The guidance is effective for public business entities for fiscal years, and for interim periods within those fiscal years, beginning after December 15, 2015, with early adoption permitted. A reporting entity must apply this guidance retrospectively to all prior periods presented in the financial statements. The Company has retrospectively adopted this guidance as of December 31, 2015 and accordingly has reclassified $7,294 of deferred financing costs from other assets to long-term debt on its consolidated balance sheet as of December 31, 2014.

The FASB issued ASU No. 2015-02, Income Statement—Consolidation, in February 2015. This guidance affects reporting entities that are required to evaluate whether they should consolidate certain legal entities. Specifically, the guidance 1) modifies the evaluation of whether limited partnerships and similar legal entities are variable interest entities or voting interest entities, 2) eliminates the presumption that a general partner should consolidate a limited partnership, 3) affects the consolidation analysis of reporting entities that are involved with VIEs, particularly those that have fee arrangements and related party relationships, and 4) provides a scope exception from consolidation guidance for reporting entities with interests in legal entities that are required to comply with or operate in accordance with requirements that are similar to those in Rule 2a-7 of the Investment Company Act of 1940 for registered money market funds. The guidance is effective for public business entities for fiscal years, and for interim periods within those fiscal years, beginning after December 15, 2015. The Company does not expect the adoption of this guidance to have a material impact on its consolidated financial statements.

The FASB issued ASU No. 2014-09, Revenue from Contracts with Customers, in September 2014. This guidance requires that an entity recognize revenue to depict the transfer of a promised good or service to its customers in an amount that reflects consideration to which the entity expects to be entitled in exchange for such transfer. This guidance also specifies accounting for certain costs incurred by an entity to obtain or fulfill a contract with a customer and provides for enhancements to revenue specific disclosures intended to allow users of the financial statements to clearly understand the nature, amount, timing and uncertainty of revenue and cash flows arising from an entity’s contracts with its customers. This guidance is effective for annual periods, and interim periods within those annual periods, beginning after December 15, 2017 for public companies.  The Company is currently evaluating the impact, if any, the adoption of this guidance will have on its consolidated financial statements.

In September 2015, the FASB issued Accounting Standards Update No. 2015-16, Business Combinations (Topic 805): Simplifying the Accounting for Measurement-Period Adjustments. This guidance requires that an acquirer recognize adjustments to provisional amounts that are identified during the measurement period in the reporting period in which the adjustment amounts are determined. The guidance is effective for fiscal years, and interim reporting periods within those fiscal years, beginning after December 15, 2015. The Company does not expect the adoption of this guidance to have a material impact on its consolidated financial statements.

In November 2015, the FASB issued Accounting Standards Update No. 2015-17, Income Taxes (Topic 740): Balance Sheet Classification of Deferred Taxes. This guidance simplifies the presentation of deferred income taxes by requiring that deferred tax liabilities and assets all be classified as noncurrent in a classified statement of financial position. The guidance is effective for fiscal years, and interim reporting periods within those fiscal years, beginning after December 15, 2016, with early adoption permitted. The Company has adopted this guidance as of December 31, 2015, with no impact to the previously reported amounts.

(3) Variable interest entities

The carrying values of VIEs included in the consolidated financial statements as of December 31, 2015 and December 31, 2014 are as follows:

The Company also has variable interests in certain franchisees mainly through the guarantee of certain debt and lease agreements as well as financing provided by the Company and by certain related parties to franchisees. The Company’s maximum obligation, as a result of its guarantees of leases and debt, is approximately $1,871 and $2,896 as of December 31, 2015 and 2014, respectively.

The amount of the Company’s maximum obligation represents a loss that the Company could incur from the variability in credit exposure without consideration of possible recoveries through insurance or other means. In addition, the amount bears no relation to the ultimate settlement anticipated to be incurred from the Company’s involvement with these entities, which is estimated at $0.

(4) Acquisition

On March 31, 2014, the Company purchased certain assets from one of its franchisees, including eight franchisee-owned stores in New York, for consideration of $42,931, including a cash payment of $39,931 and a $3,000 discount to be applied to future equipment purchases. The $3,000 equipment discount was initially recorded as deferred revenue by the Company and is being recognized as equipment sales are made by the Company to the franchisee. In addition, as a result of the transaction, the Company incurred a loss on unfavorable reacquired franchise rights of $1,293, which has been reflected in other operating costs in the statement of operations. The loss incurred reduced the net purchase price to $41,638. The Company financed the purchase through borrowings under its credit facility. The purchase consideration was allocated as follows:

(5) National advertising fund

On July 26, 2011, the Company established Planet Fitness NAF, LLC (“NAF”) for the creation and development of marketing, advertising, and related programs and materials for all Planet Fitness stores located in the United States and Puerto Rico. On behalf of the NAF, the Company collects 2% of gross monthly membership billings from franchisees, in accordance with the provisions of the franchise agreements. The Company also contributes 2% of monthly membership billings from stores owned by the Company to the NAF. The use of amounts received by NAF is restricted to advertising, product development, public relations, merchandising, and administrative expenses and programs to increase sales and further enhance the public reputation of the Planet Fitness brand. The Company consolidates and reports all assets and liabilities held by the NAF within the consolidated financial statements. Amounts received or receivable by NAF are reported as restricted assets and restricted liabilities within current assets and current liabilities on the consolidated balance sheets. The Company provides administrative services to NAF and charges NAF a fee for providing those services. These services include accounting services, information technology, data processing, product development, legal and administrative support, and other operating expenses, which amounted $1,340, $1,010 and $865 for the years ended December 31, 2015, 2014 and 2013, respectively. The fees paid to the Company by NAF are included in the consolidated statements of operations as a reduction in general and administrative expense, where the expense incurred by the Company was initially recorded.

(6) Notes Receivable

Prior to December 31, 2015, the Company had various notes receivable from franchisees to facilitate ongoing business. Notes receivable consisted of unpaid principal and accrued interest. There were two notes receivable as of December 31, 2014, with maturity dates ranging from July 1, 2015 to February 1, 2018, however, all notes receivable were settled in cash during 2015; as such, no amounts are outstanding as of December 31, 2015.

Amortization expense related to the intangible assets totaled $21,543, $23,698, and $22,883 for the years ended December 31, 2015, 2014, and 2013, respectively. Included within these total amortization expense amounts are $473, $495, and $246 related to amortization of favorable and unfavorable leases for the years ended December 31, 2015, 2014, and 2013, respectively. Amortization of favorable and unfavorable leases is recorded within store operations as a component of rent expense in the consolidated statements of operations. The anticipated annual amortization expense to be recognized in future years as of December 31, 2015 is as follows:

(9) Long-term debt

Long-term debt as of December 31, 2015 and 2014 consists of the following:  

On March 31, 2014, the Company entered into a five-year $430,000 credit facility with a consortium of banks and lenders to refinance its existing indebtedness, as well as to provide funds for working capital, capital expenditures, acquisitions, a $173,900 dividend and general corporate purposes. The facility consisted of a $390,000 Term Loan and a $40,000 Revolving Credit Facility. On March 31, 2015, the Company amended this credit facility to increase the Term Loan to $510,000 to fund a cash dividend of $140,000. The unused portion of the Revolving Credit Facility as of December 31, 2015 was $40,000. The Term Loan calls for quarterly principal installment payments of $1,275 through March 2021.

The credit facility requires the Company to meet certain financial covenants, which the Company was in compliance with as of December 31, 2015. The facility is secured by all of the Company’s assets, excluding the assets attributable to the consolidated VIEs (see Note 3).

Future annual principal payments of long-term debt as of December 31, 2015 are as follows:  

(10) Derivative instruments and hedging activities

The Company utilizes interest-rate-related derivative instruments to manage its exposure related to changes in interest rates on its variable-rate debt instruments. The Company does not enter into derivative instruments for any purpose other than cash flow hedging. The Company does not speculate using derivative instruments.

By using derivative financial instruments to hedge exposures to changes in interest rates, the Company exposes itself to credit risk and market risk. Credit risk is the failure of the counterparty to perform under the terms of the derivative contract. When the fair value of a derivative contract is an asset, the counterparty owes the Company, which creates credit risk for the Company. When the fair value of a derivative contract is a liability, the Company owes the counterparty and, therefore, the Company is not exposed to the counterparty’s credit risk in those circumstances. The Company minimizes counterparty credit risk in derivative instruments by entering into transactions with high-quality counterparties whose credit rating is higher than A1/A+ at the inception of the derivative transaction. The derivative instruments entered into by the Company do not contain credit-risk-related contingent features.

Market risk is the adverse effect on the value of a derivative instrument that results from a change in interest rates. The market risk associated with interest-rate contracts is managed by establishing and monitoring parameters that limit the types and degree of market risk that may be undertaken.

The Company assesses interest rate risk by continually identifying and monitoring changes in interest rate exposures that may adversely impact expected future cash flows and by evaluating hedging opportunities. The Company monitors interest rate risk attributable to both the Company’s outstanding or forecasted debt obligations as well as the Company’s offsetting hedge positions.

During 2014, the Company utilized LIBOR-based interest rate swap agreements that were entered into to manage fluctuations in cash flows resulting from changes in the benchmark interest rate of LIBOR. It was determined on March 31, 2014 that the hedge was ineffective and expense of $92 was reclassified from other comprehensive income to interest expense. The interest rate swaps were all terminated by September 2014. The Company recorded a loss of $248 within interest expense in the consolidated statement of operations for the year ending December 31, 2014 related to these terminated swap agreements.  

In September 2014, the Company entered into a series of LIBOR based interest rate cap agreements in exchange for premium payments of $2,373 to effectively manage interest rate risk above a certain threshold and mitigate exposure to changes in interest rates under the term loan. The interest rate caps entered into in September 2014 were for a total notional amount of $194,000. The term of the interest rate caps began on September 30, 2014 and ends on September 29, 2017. In September 2015, the Company entered into two additional caps for premium payments of $880, which were effective September 30, 2015 and end on September 30, 2018. The interest rate cap agreements are designed to cap the LIBOR interest rate into a fixed interest rate if the LIBOR goes above the set cap amounts of 1.5%. As of December 31, 2015, the Company had interest rate cap agreements with notional amounts of $238,000 outstanding.

Changes in the fair value of interest rate swaps and caps designated as hedging instruments that effectively offset the variability of cash flows associated with variable-rate, long-term debt obligations are reported in accumulated other comprehensive income. These amounts subsequently are reclassified into interest expense as a yield adjustment of the hedged interest payments in the same period in which the related interest affects earnings.

The interest rate cap balances of $1,147 and $1,711 were recorded within other assets in the consolidated balance sheets as of December 31, 2015 and 2014, respectively. These amounts have been measured at fair value and are considered to be a Level 2 fair value measurement. The Company recorded a reduction to the value of its interest rate caps of $1,388, net of tax of $28, within other comprehensive loss during the year ended December 31, 2015. The Company recorded a reduction to the interest rate cap of $662 within other comprehensive loss as of December 31, 2014.

As of December 31, 2015, the Company does not expect to reclassify any amounts included in accumulated other comprehensive income (loss) into earnings during the next 12 months. Transactions and events expected to occur over the next twelve months that will necessitate reclassifying these derivatives’ loss to earnings include the re-pricing of variable-rate debt.

(11) Deferred revenue

The summary set forth below represents the balances in deferred revenue as of December 31, 2015 and 2014:

Equipment deposits received in advance of delivery, placement and customer acceptance as of December 31, 2015 and 2014 were $5,587 and $6,675, respectively and are expected to be recognized as revenue in the next twelve months.

(12) Related party transactions

In connection with the IPO, the Company paid a $1,000 termination fee related to the termination of its management agreement with TSG, which is included in the management fees paid for the year ended December 31, 2015. As of December 31, 2015, the Company had $140,191 payable to related parties pursuant to tax benefit arrangements, see Note 16.

(13) Stockholder’s equity

The recapitalization transactions

The Company refers to the Merger, Reclassification and entry into the Exchange agreement, each as described below, as the “recapitalization transactions.” The Merger was effected pursuant to a merger agreement by and among the Company and Planet Fitness Holdings, L.P. (a predecessor entity to the Company) and the recapitalization transactions were effected pursuant to a recapitalization agreement by and among the Company, Pla-Fit Holdings, the Continuing LLC Owners and Direct TSG Investors.

Merger

Prior to the Merger, the Direct TSG Investors held interests in Planet Fitness Holdings, L.P., a predecessor entity to the Company that held indirect interests in Pla-Fit Holdings. Planet Fitness Holdings, L.P. was formed in October 2014 and had no material assets, liabilities or operations, other than as a holding company owning indirect interests in Pla-Fit Holdings. The Direct TSG Investors consist of investment funds affiliated with TSG. Pursuant to a merger agreement dated June 22, 2015, upon the pricing of the IPO, Planet Fitness Holdings, L.P. merged with and into the Company, and the interests in Planet Fitness Holdings, L.P. held by the Direct TSG Investors were converted into 26,106,930 shares of Class A common stock of the Company. The Company refers to this as the “Merger.” All shares of Class A common stock have both voting and economic rights in Planet Fitness, Inc.

The Merger was effected on August 5, 2015, prior to the time our Class A common stock was registered under the Exchange Act and prior to the completion of the IPO.

Reclassification

The equity interests of Pla-Fit Holdings previously consisted of three different classes of limited liability company units (Class M, Class T and Class O). Prior to the completion of the IPO, the limited liability company agreement of Pla-Fit Holdings was amended and restated to, among other things, modify its capital structure to create a single new class of units, the Holdings Units. The Company refers to this capital structure modification as the “Reclassification.”

The Direct TSG Investors’ indirect interest in Pla-Fit Holdings was held through Planet Fitness Holdings, L.P. As a result, following the Merger, in which Planet Fitness Holdings, L.P. merged with and into the Company, the Direct TSG Investors’ indirect interests in Pla-Fit Holdings are held through the Company. Therefore, the Holdings Units received in the Reclassification were allocated to: (1) the Continuing LLC Owners based on their existing interests in Pla-Fit Holdings; and (2) the Company to the extent of the Direct TSG Investors’ indirect interest in Pla-Fit Holdings. The number of Holdings Units allocated to the Company in the Reclassification was equal to the number of shares of Class A common stock that the Direct TSG Investors received in the Merger (on a one-for-one basis).

The Reclassification was effected on August 5, 2015, prior to the time our Class A common stock was registered under the Exchange Act and prior to the completion of the IPO.

Following the Merger and the Reclassification, the Company issued to Continuing LLC Owners 72,602,810 shares of Class B common stock, one share of Class B common stock for each Holdings Unit they held. The shares of Class B common stock have no rights to dividends or distributions, whether in cash or stock, but entitle the holder to one vote per share on matters presented to stockholders of the Company. The Continuing LLC Owners consist of investment funds affiliated with TSG and certain employees and directors.

Pursuant to the LLC agreement that went into effect at the time of the Reclassification (“New LLC Agreement”), the Company was designated as the sole managing member of Pla-Fit Holdings. Accordingly, the Company has the right to determine when distributions will be made by Pla-Fit Holdings to its members and the amount of any such distributions (subject to the requirements with respect to the tax distributions described below). If the Company authorizes a distribution by Pla-Fit Holdings, the distribution will be made to the members of Pla-Fit Holdings, including the Company, pro rata in accordance with the percentages of their respective Holdings Units.

The holders of Holdings Units will incur U.S. federal, state and local income taxes on their allocable share of any taxable income of Pla-Fit Holdings (as calculated pursuant to the New LLC Agreement). Net profits and net losses of Pla-Fit Holdings will generally be allocated to its members pursuant to the New LLC Agreement pro rata in accordance with the percentages of their respective Holdings Units. The New LLC Agreement provides for cash distributions to the holders of Holdings Units for purposes of funding their tax obligations in respect of the income of Pla-Fit Holdings that is allocated to them, to the extent other distributions from Pla-Fit Holdings for the relevant year have been insufficient to cover such liability. Generally, these tax distributions are computed based on the estimated taxable income of Pla-Fit Holdings allocable to the holders of Holdings Units multiplied by an assumed, combined tax rate equal to the maximum rate applicable to an individual or corporation resident in San Francisco, California (taking into account the non-deductibility of certain expenses and the character of the Company’s income).

Exchange agreement

Following the Merger and the Reclassification, the Company and the Continuing LLC Owners entered into an exchange agreement under which the Continuing LLC Owners (or certain permitted transferees thereof) have the right, from time to time and subject to the terms of the exchange agreement, to exchange their Holdings Units, along with a corresponding number of shares of Class B common stock, for shares of Class A common stock (or cash at the option of the Company) on a one-for-one basis, subject to customary conversion rate adjustments for stock splits, stock dividends, reclassifications and similar transactions. As a Continuing LLC Owner exchanges Holdings Units, along with a corresponding number of shares of Class B common stock, for shares of Class A common stock, the number of Holdings Units held by the Company will increase by a corresponding amount as it acquires the exchanged Holdings Units and cancels a corresponding number of shares of Class B common stock.

Offering transactions

In connection with the completion of the IPO on August 11, 2015, in order to facilitate the disposition of equity interests in Pla-Fit Holdings held by Continuing LLC Owners affiliated with TSG, the Company used the net proceeds received to purchase issued and outstanding Holdings Units from these Continuing LLC Owners that they received in the Reclassification. In connection with the IPO, the Company purchased 10,491,055 issued and outstanding Holdings Units from these Continuing LLC Owners for an aggregate of $156,946. This is in addition to the 26,106,930 Holdings Units that the Company acquired in the Reclassification on a one-for-one basis in relation to the number of shares of Class A common stock issued to the Direct TSG Investors in the Merger. Accordingly, following the IPO, the Company holds 36,597,985 Holdings Units, which is equal to the number of shares of Class A common stock that were issued to the Direct TSG Investors and investors in the IPO. The Direct TSG Investors, who did not receive Holdings Units in the Reclassification but received shares of Class A common stock in the Merger, sold 5,033,945 shares of Class A common stock in the IPO as selling stockholders. All expenses of the IPO, other than underwriter discounts and commissions, were borne by Pla-Fit Holdings or reimbursed by Pla-Fit Holdings to the Company and amounted to $7,697 for the year ended December 31, 2015. These amounts were recorded in selling, general, and administrative expense in the accompanying statements of operations and could not be capitalized and offset against the proceeds from the offering because the Company did not retain any of the proceeds from the IPO.

As a result of the recapitalization transactions and the offering transactions, upon completion of the IPO:

(14) Equity-based compensation

2013 Equity Incentive Plan

In 2013, the Company’s Board of Directors adopted the 2013 Equity Incentive Plan (the “2013 Plan”). Under the 2013 Plan, the Company has granted awards in the form of Class M Units to employees and directors of the Company and its subsidiaries. The Class M Units receive distributions (other than tax distributions) only upon a liquidity event, as defined, that exceeds a threshold equivalent to the fair value of the Company, as determined by the Company’s Board of Directors, at the grant date. Eighty percent of the awards vest over five years of continuous employment or service while the other twenty percent only vest in the event of an initial public offering of the Company’s common stock or that of its parent or one of its subsidiaries, subject to the holder of the Class M Units remaining employed or providing services on the date of such initial public offering. All awards include a repurchase option at the election of the Company for the vested portion upon termination of employment or service, and have a ten year contractual term. These awards are accounted for as equity at their fair value as of the grant date.

The fair value of each award was estimated on the date of grant using a Monte Carlo simulation model.  

The weighted average assumptions for the grants are provided in the following table. Since the Company’s shares were not publicly traded, expected volatility was estimated based on the average historical volatility of similar entities with publicly traded shares. The term was based on the estimated time to a liquidity event. The risk-free rate for the expected term of the M Unit was is based on the U.S. Treasury yield curve at the date of grant.

Valuation assumptions:

During the year ended December 31, 2015, the Company modified the vesting terms of 10.737 outstanding Class M Units such that those units are fully vested and eligible to receive distributions following a liquidity event. In connection with the IPO and related recapitalization transactions as described in Note 1, all of the outstanding Class M Units were converted into Holdings Units and Class B common shares of Planet Fitness, Inc. in accordance with the terms of the awards. The Company’s IPO constituted a qualifying event under the terms of the awards and as a result 4,238,338 Holdings Units and corresponding Class B Common shares were issued to the existing Class M Unit holders with a weighted-average grant date fair value of $1.52 per share. The Company recorded $4,731 of compensation expense in the year ended December 31, 2015 related to these awards. The amount of total unrecognized compensation cost related to all awards under this plan was $729 as of December 31, 2015, which is expected to be recognized over a weighted-average period of 2.4 years.

A summary of Class M Unit activity is presented below:

The weighted average grant-date fair value of the Class M Units vested during the years ended December 31, 2014 and 2013 was $10,047 and $10,656 per unit, respectively. During the years ended December 31, 2014 and 2013, 69.052 and 24.421 units vested, respectively, but were not yet exercisable due to the fact that exercisability was contingent on a liquidity event. No distributions were paid under these awards in 2013 or 2014 and no awards were forfeited in 2013.

2015 Omnibus Incentive Plan

Stock Options

In August 2015, the Company adopted the 2015 Omnibus Incentive Plan (the "2015 Plan") under which the Company may grant options and other equity-based awards to purchase up to 7,896,800 shares to employees, directors and officers. In connection with the IPO, the Company granted options to purchase up to 106,030 shares to certain employees with an exercise price of $16.00 per share. Options to purchase an additional 10,660 shares were granted during the year ended December 31, 2015, with an exercise price of $17.50 per share. All stock options awarded vest annually, on a tranche by tranche basis, over a period of four years.

The fair value of stock option awards granted during the year ended December 31, 2015 was determined on the grant date using the Black-Scholes valuation model based on the following weighted-average assumptions:

A summary of stock option activity for the year ended December 31, 2015: 

The weighted-average grant date fair value of stock options granted during the year ended December 31, 2015 was $6.14. During the year ended December 31, 2015, $131 was recorded to selling, general and administrative expense related to these stock options. As of December 31, 2015, there were 108,270 stock options outstanding none of which were exercisable. The aggregate intrinsic value of stock options outstanding as of December 31, 2015 was $0. As of December 31, 2015, total unrecognized compensation expense related to unvested stock options, including an estimate for pre-vesting forfeitures, was $514, which is expected to be recognized over a weighted-average period of 3.6 years.

Restricted stock units

During the year ended December 31, 2015, the Company granted 8,160 restricted Class A stock units (“RSUs”) to one member of its Board of Directors under the 2015 Plan. The RSUs granted vest in three equal annual installments beginning on first anniversary of the grant date, provided that the recipient continues to serve on the Board of Directors through the vesting dates.

The weighted-average grant date fair value of RSUs granted during the year ended December 31, 2015 was $18.38. During the year ended December 31, 2015, $26 was recorded to selling, general and administrative expense related to these RSUs. As of December 31, 2015, there were 8,160 RSUs outstanding none of which were exercisable. As of December 31, 2015, total unrecognized compensation expense related to unvested RSUs, including an estimate for pre-vesting forfeitures was $124, which is expected to be recognized over a weighted-average period of 2.7 years.

(15) Earnings per share

Basic earnings per share of Class A common stock is computed by dividing net income attributable to Planet Fitness, Inc. for the period from August 6, 2015 through December 31, 2015, the period following the recapitalization transactions and IPO, by the weighted-average number of shares of Class A common stock outstanding during the same period. Diluted earnings per share of Class A common stock is computed by dividing net income attributable to Planet Fitness, Inc. by the weighted-average number of shares of Class A common stock outstanding adjusted to give effect to potentially dilutive securities. There were no shares of Class A or Class B common stock outstanding prior to August 6, 2015, therefore no earnings per share information has been presented for any period prior to that date.

Shares of the Company’s Class B common stock do not share in the earnings or losses attributable to Planet Fitness, Inc. and are therefore not participating securities. As such, separate presentation of basic and diluted earnings per share of Class B common stock under the two-class method has not been presented. Shares of the Company’s Class B common stock are, however, considered potentially dilutive shares of Class A common stock because shares of Class B common stock, together with the related Holdings Units, are exchangeable into shares of Class A common stock on a one-for-one basis.

The following table sets forth reconciliations of the numerators and denominators used to compute basic and diluted earnings per share of Class A common stock:

Class B common stock was evaluated under the if-converted method for potential dilutive effects and were determined to be anti-dilutive. Stock options in the amount of 108,270 and restricted stock units in the amount of 8,160 were evaluated under the treasury stock method for potential dilutive effects and were determined to be anti-dilutive.

(16) Income taxes

Income before the provision for income taxes as shown in the accompanying consolidated statements of operations is as follows:

The provision (benefit) for income taxes consists of the following:
