SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)

12 Months Ended

Dec. 30, 2020

Accounting Policies [Abstract]

Basis of Presentation

Basis of Presentation

The accompanying consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) and include our accounts and the accounts of our subsidiaries. All intercompany accounts and transactions have been eliminated in consolidation. Certain reclassifications have been made to prior period amounts to conform to the current year presentation.

SSE Holdings is considered a variable interest entity. Shake Shack Inc. is the primary beneficiary as we have the majority economic interest in SSE Holdings and, as the sole managing member, have decision making authority that significantly affects the economic performance of the entity, while the limited partners have no substantive kick-out or participating rights. As a result, we will continue to consolidate SSE Holdings. The assets and liabilities of SSE Holdings represent substantially all of our consolidated assets and liabilities with the exception of certain deferred taxes and liabilities under the Tax Receivable Agreement. As of December 30, 2020 and December 25, 2019, the net assets of SSE Holdings were $383,669 and $270,542, respectively. The assets of SSE Holdings are subject to certain restrictions in SSE Holdings' revolving credit agreements. See Note 9, Debt, for more information.

Fiscal Year

Fiscal Year

We operate on a 52/53 week fiscal year ending on the last Wednesday in December. Fiscal year 2020 contained 53 weeks and ended on December 30, 2020 ("fiscal 2020"). Fiscal years 2019 and 2018 each contained 52 weeks and ended on December 25, 2019 ("fiscal 2019") and December 26, 2018 ("fiscal 2018"), respectively. Unless otherwise stated, references to years in this report relate to fiscal years.

Use of Estimates

Use of Estimates

The preparation of these consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of sales and expenses during the reporting period. Significant estimates inherent in the preparation of the consolidated financial statements include useful lives and impairments of long-lived tangible and intangible assets, accounting for income taxes and related uncertain tax positions, the valuation of equity-based compensation and awards, and reserves for litigation and other contingencies, amongst others. Actual results could differ from those estimates.

Segment Reporting

Segment Reporting

We own and operate Shacks in the United States. We also have domestic and international licensed operations. Our chief operating decision makers (the "CODMs") are our Chief Executive Officer and our President and Chief Financial Officer. As the CODMs review financial performance and allocate resources at a consolidated level on a recurring basis, we have one operating segment and one reportable segment.

Fair Value Measurements

Fair Value Measurements

We apply fair value accounting for all financial assets and liabilities and non-financial assets and liabilities that are recognized or disclosed at fair value in the financial statements on a recurring basis. We categorize our assets and liabilities, based on the priority of the inputs to the valuation technique, into a three-level fair value hierarchy as set forth below. The three levels of the hierarchy are defined as follows:

▪Level 1 — Unadjusted quoted prices in active markets for identical assets or liabilities

▪Level 2 — Observable inputs other than quoted prices in active markets for identical assets or liabilities, quoted prices for identical assets or liabilities in inactive markets, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities

▪Level 3 — Inputs that are both unobservable and significant to the overall fair value measurements reflecting an entity's estimates of assumptions that market participants would use in pricing the asset or liability.

Cash and Cash Equivalents

Cash and Cash Equivalents

Cash and cash equivalents consist primarily of cash on hand, deposits with banks, and short-term, highly liquid investments that have original maturities of three months or less. Cash equivalents are stated at cost, which approximates fair value. In fiscal 2019, cash equivalents consist primarily of money market funds.

Marketable Securities

Marketable securities consist of mutual funds that primarily invest in corporate bonds, certificates of deposits, asset-backed securities, commercial paper, U.S. Treasury obligations, and foreign government securities. Marketable securities are recorded at fair value, with unrealized gains and losses recorded in Other income, net. Dividend and interest income are recognized when earned and are recorded in Other income (expense), net on the consolidated statements of income (loss).

Accounts Receivable

Accounts Receivable, NetAccounts receivable consist primarily of receivables from our licensees for licensing revenue and related reimbursements, credit card receivables and vendor rebates. We evaluate the collectibility of our accounts receivable based on a variety of factors, including historical experience, current economic conditions and other factors.

Inventories

Inventories

Inventories, which consist of food, paper goods, beverages, beer, wine and retail merchandise, are valued at the lower of weighted-average cost or net realizable value. No adjustment is deemed necessary to reduce inventory to net realizable value due to the rapid turnover and high utilization of inventory.

Property and Equipment

Property and Equipment, Net

Property and equipment, net is stated at historical cost less accumulated depreciation. Property and equipment is depreciated based on the straight-line method over the estimated useful lives of the assets, generally ranging from five to seven years for both equipment, and furniture and fixtures, and two to five years for computer equipment and software. Leasehold improvements are depreciated over the shorter of their estimated useful lives or the related lease terms.

Costs incurred when constructing Shacks are capitalized. The cost of repairs and maintenance are expensed when incurred. Costs for refurbishments and improvements that significantly increase the productive capacity or extend the useful life of the asset are capitalized. When assets are disposed of, the resulting gain or loss is recognized in Impairment and loss on disposal of assets on the Consolidated Statements of Income (Loss).

Valuation of Long-lived Assets

We assess potential impairments to our long-lived assets, which includes property and equipment and operating lease right-of-use assets, whenever events or circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of an asset is measured by a comparison of the carrying amount of the asset group to the estimated undiscounted future cash flows expected to be generated by the asset group. If the carrying amount of the asset group exceeds its estimated undiscounted future cash flows, an impairment charge is recognized as the amount by which the carrying amount of the asset exceeds the fair value of the asset, considering external market participant assumptions. Since the determination of future cash flows is an estimate of future performance, there may be future impairments in the event that future cash flows do not meet expectations.

Deferred Financing Costs

Deferred Financing Costs

Deferred financing costs incurred in connection with the issuance of long-term debt and establishing credit facilities are capitalized and amortized to interest expense based on the related debt agreements. Deferred financing costs are included in Other assets on the Consolidated Balance Sheets.

Other Assets

Other Assets

Other assets consist primarily of capitalized implementation costs from cloud computing arrangements, transferable liquor licenses, certain custom furniture pre-ordered for future Shacks and yet to be placed in service and security deposits.

The costs of obtaining non-transferable liquor licenses that are directly issued by local government agencies for nominal fees are expensed as incurred. The costs of purchasing transferable liquor licenses through open markets in jurisdictions with a limited number of authorized liquor licenses are capitalized as indefinite-lived intangible assets. Annual liquor license renewal fees are expensed over the renewal term. As of both December 30, 2020 and December 25, 2019, indefinite-lived intangible assets relating to transferable liquor licenses totaled $1,437. We evaluate our indefinite-lived intangible assets for impairment annually during our fiscal fourth quarter, and whenever events or changes in circumstances indicate that an impairment may exist. When evaluating intangible assets for impairment, we may first perform a qualitative assessment to determine whether it is more likely than not that an intangible asset group is impaired. If we do not perform the qualitative assessment, or if we determine that it is not more likely than not that the fair value of the intangible asset group exceeds its carrying amount, we calculate the estimated fair value of the intangible asset group. If the carrying amount of the intangible asset group exceeds the estimated fair value, an impairment charge is recorded to reduce the carrying value to the estimated fair value. In addition, we continuously monitor and may revise our intangible asset useful lives if and when facts and circumstances change.

Equity-based Compensation

Equity-based Compensation

Equity-based compensation expense is measured based on the grant-date fair value of those awards. For awards with graded-vesting features and service conditions only, compensation expense is recognized on a straight-line basis over the total requisite service period for the entire award. For awards with graded-vesting features and a combination of service and performance conditions, compensation expense is recognized using a graded-vesting attribution method over the vesting period based on the most probable outcome of the performance conditions. Actual distributed shares are calculated upon conclusion of the service and performance periods. For stock option awards, the grant-date fair value of the awards is determined using the Black-Scholes option pricing model and involves several assumptions, including the expected term of the option, expected volatility and risk-free interest rate. Forfeitures are recognized as they occur for all equity awards. Equity-based compensation expense is included within General and administrative expenses and Labor and related expenses on the Consolidated Statements of Income (Loss).

Leases

Leases

On December 27, 2018 we adopted Accounting Standards Update (“ASU”) 2016-02, Leases (Topic 842), using a modified retrospective approach. Refer to Note 10, Leases, for further details.

We currently lease all of our domestic Company-operated Shacks, our home office and certain equipment under various non-cancelable lease agreements that expire on various dates through 2037. Upon the possession of a leased asset, we determine its classification as an operating or financing lease. All of our real estate leases are classified as operating leases and most of our equipment leases are classified as finance leases.

Generally, our real estate leases have initial terms ranging from 10 to 15 years and typically include two five-year renewal options. Renewal options are typically not included in the lease term as it is not reasonably certain at commencement date that we would exercise the options to extend the lease. Our real estate leases typically provide for fixed minimum rent payments and/or contingent rent payments based upon sales in excess of specified thresholds. When the achievement of such sales thresholds are deemed to be probable, contingent rent is accrued in proportion to the sales recognized during the period. Fixed minimum rent payments are recognized on a straight-line basis over the lease term starting on the date we take possession of the leased property. Lease expense incurred before a Shack opens is recorded in Pre-opening costs. Once a Shack opens, we record the straight-line lease expense and any contingent rent, if applicable, in Occupancy and related expenses on the Consolidated Statements of Income. Many of our leases also require us to pay real estate taxes, common area maintenance costs and other occupancy costs which are included in Occupancy and related expenses on the Consolidated Statements of Income (Loss).

We calculate operating lease assets and lease liabilities as the present value of fixed lease payments over the reasonably certain lease term beginning at the commencement date. We measure the lease liability by discounting the future fixed

contractual payments included in the lease agreement, using our incremental borrowing rate (“IBR”). There are no explicit rates provided in our leases. The IBR is derived from the average of the yield curves obtained from using the notching method and the recovery rate method. The most significant assumption in calculating the incremental borrowing rate is our credit rating. We determined our credit rating based on a comparison of the financial information of SSE Holdings to other public companies and then used their respective credit ratings to develop our own.

For operating leases, fixed lease payments are recognized as operating lease cost on a straight-line basis over the lease term. For finance leases, the asset is depreciated on a straight-line basis over the remaining lease term, along with recognition of interest expense associated with accretion of the lease liability. For leases with a lease term of 12 months or less ("short-term lease"), any fixed lease payments are recognized on a straight-line basis over such term, and are not recognized on the Consolidated Balance Sheets. Variable lease cost for both operating and finance leases, if any, is recognized as incurred.

We expend cash for leasehold improvements to build out and equip our leased premises. Generally, a portion of the leasehold improvements and building costs are reimbursed by our landlords as landlord incentives pursuant to agreed-upon terms in our lease agreements. If obtained, landlord incentives usually take the form of up-front cash, full or partial credits against our future minimum or contingent rents otherwise payable by us, or a combination thereof. In most cases, landlord incentives are received after we take possession of the property, as we meet required milestones during the construction of the property. We include these amounts in the measurement of the initial operating lease liability, which are also reflected as a reduction to the initial measurement of the right-of-use asset.

Pre-opening Costs

Pre-opening costs are expensed as incurred and consist primarily of occupancy, manager and employee wages, legal fees, travel and related training costs, cookware and marketing expenses incurred prior to the opening of a Shack.

Income Taxes

Income Taxes

We account for income taxes pursuant to the asset and liability method which requires the recognition of deferred income tax assets and liabilities related to the expected future tax consequences arising from temporary differences between the carrying amounts and tax bases of assets and liabilities based on enacted statutory tax rates applicable to the periods in which the temporary differences are expected to reverse. Any effects of changes in income tax rates or laws are included in income tax expense in the period of enactment. A valuation allowance is recognized if we determine it is more likely than not that all or a portion of a deferred tax asset will not be recognized. In making such determination, the Company considers all available evidence, including scheduled reversals of deferred tax liabilities, projected future taxable income, tax planning strategies and recent and expected future results of operation.

Recently Issued Accounting Pronouncements

Recently Adopted Accounting Pronouncements     

We adopted the Accounting Standards Update ("ASU") summarized below in fiscal 2020.

ASU			Description			Date Adopted
Measurement of Credit Losses on Financial Instruments (ASU 2016-13)			This standard replaces the incurred loss impairment methodology in current GAAP with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates. The adoption of this standard did not have a material impact to our consolidated financial statements.			December 26, 2019
Facilitation of the Effects of Reference Rate Reform on Financial Reporting (ASU 2020-04)			This standard provides optional guidance for a limited time to ease the potential accounting burden associated with transitioning away from reference rates that are expected to be discontinued. The adoption of this standard did not have a material impact to our consolidated financial statements.			Effective upon issuance (March 12, 2020)
