Basis of Presentation and Critical Accounting Policies | BASIS OF PRESENTATION AND CRITICAL ACCOUNTING POLICIES The consolidated condensed balance sheet as of September 28, 2019 , which has been derived from audited consolidated financial statements included in the Company’s annual report on Form 10-K for the year ended September 28, 2019 (“Form 10-K”), and the unaudited interim consolidated condensed financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) for interim financial information and pursuant to the rules and regulations of the Securities and Exchange Commission (the “SEC”). Accordingly, certain information and footnote disclosures normally included in financial statements prepared in accordance with GAAP have been condensed or omitted. All adjustments that, in the opinion of management are necessary for a fair presentation for the periods presented, have been reflected as required by Article 10 of Regulation S-X. Such adjustments are of a normal, recurring nature. These consolidated condensed financial statements should be read in conjunction with the consolidated financial statements and notes thereto included in the Form 10-K. COVID-19 PANDEMIC — On March 11, 2020, in light of the rapid spread of the novel Coronavirus (“COVID-19” or "Coronavirus"), the World Health Organization declared the COVID-19 outbreak to be a global pandemic and the United States declared a National Public Health Emergency. The COVID-19 pandemic has significantly impacted health and economic conditions throughout the United States. Federal, state and local governments took a variety of actions to contain the spread of COVID-19 and the Company was required to temporarily close its restaurants during March 2020, with all locations closed as of March 28, 2020, until the related governmental authorities allow us to reopen them. The Coronavirus has caused unprecedented business disruptions, especially in the hospitality industry, and the Company fully supports all governmental actions to help stem the effects of the Coronavirus. While neither the length of time of the closures nor the extent of the impact of the Coronavirus on our results of operations and financial condition may be known for quite some time, we do expect that there will be a material adverse effect. As a result of these developments, the Company is experiencing a significant negative impact on its revenues, results of operations and cash flows, which could negatively impact its ability to meet its obligations over the next twelve months. As of March 28, 2020, the Company had a working capital deficit of ( $10,023,000 ). However, we believe that our existing cash balances, current credit facilities and the actions taken that are listed below will be sufficient to meet our liquidity and capital spending requirements through June 24, 2021. In response to the business disruption and liquidity concerns caused by the COVID-19 pandemic, the Company has taken the following actions, which management expects will enable it to meet its obligations over the next twelve months: • Furloughed all hourly employees and approximately 95% of restaurant management personnel, while enacting temporary salary reductions for all remaining restaurant management personnel. In addition, the Company temporarily reduced the pay of all corporate and administrative staff by 50% to 75% , temporarily reduced senior management salaries by 75% to 95% , and temporarily suspended all board fees. • Subsequent to the second quarter of 2020, the Company entered into a Payment Suspension Agreement with its bank which deferred all monthly interest payments through June 1, 2020 and deferred aggregate principal payments of $675,000 due on June 1, 2020 to the respective loan maturity dates. In addition, our bank agreed to relaxed financial covenants through fiscal Q3 2021 (see Note 7 – Notes Payable - Bank). • Indefinitely deferred the payment of the $0.25 dividend declared on March 2, 2020. • Suspended future dividend payments until such time as the Board deems appropriate to reinstate. • Canceled or delayed all non-essential capital expenditures. • Suspended the vast majority of lease payments for the months of April, May and June 2020 and is currently in negotiations for rent concessions, abatements and deferrals with its landlords to reduce these lease payments. While some landlords have agreed to certain concessions subsequent to quarter end, there can be no assurance that the Company will be successful in obtaining all of the relief it is seeking. • Certain Company subsidiaries applied for and received approximately $14.9 million of loans under the Paycheck Protection Program of the Coronavirus Aid, Relief and Economic Security Act (the “CARES Act”), which was enacted March 27, 2020 (see Note 14 – Subsequent Events). • Utilized additional provisions of the CARES Act to obtain tax savings as well as the deferral of our portion of social security taxes to future years. The full impact of the COVID-19 outbreak continues to evolve as of the date of this report. Management is continually evaluating the impact of the global crisis on its financial condition, liquidity, operations, suppliers, industry, and workforce and will take additional actions as necessary. The disruption in operations has led the Company to consider the impact of the COVID-19 pandemic on its liquidity, debt covenant compliance, and recoverability of long-lived and ROU assets, goodwill and intangible assets, among others. If these disruptions continue, the Company expects a continued material negative impact on its consolidated financial condition, future results of operations and liquidity. The extent of such negative impact will be determined, in part, by the longevity and severity of the pandemic. Due to the rapid development and fluidity of this situation, the Company cannot determine the ultimate impact that the COVID-19 pandemic will have on the Company’s consolidated financial condition, liquidity, and future results of operations, and therefore any prediction as to the ultimate material adverse impact on the Company’s consolidated financial condition, liquidity, and future results of operations is uncertain. We cannot predict how soon we will be able to reopen all of our restaurants at full capacity, and our ability to reopen will depend in part on the actions of a number of governmental bodies over which we have no control. Moreover, once restrictions are lifted, it is unclear how quickly customers will return to our restaurants, which may be a function of continued concerns over safety and/or depressed consumer sentiment due to adverse economic conditions, including job losses. PRINCIPLES OF CONSOLIDATION — The consolidated condensed financial statements include the accounts of Ark Restaurants Corp. and all of its wholly-owned subsidiaries, partnerships and other entities in which it has a controlling interest, collectively herein referred to as the “Company”. Also included in the consolidated condensed financial statements are certain variable interest entities (“VIEs”). All significant intercompany balances and transactions have been eliminated in consolidation. USE OF ESTIMATES — The preparation of financial statements in conformity with GAAP requires us 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 revenues and expenses during the reporting period. The accounting estimates that require management’s most difficult and subjective judgments include projected cash flow, allowances for potential bad debts on receivables, assumptions regarding discount rates related to lease accounting, the useful lives and recoverability of its assets, such as property and intangibles, fair values of financial instruments and share-based compensation, the realizable value of its tax assets and determining when investment impairments are other-than-temporary. Because of the uncertainty in such estimates, actual results may differ from these estimates. The results of operations for the 13 and 26 weeks ended March 28, 2020 are not necessarily indicative of the results to be expected for any other interim period or for the year ending October 3, 2020 . RECLASSIFICATIONS — Certain reclassifications of prior period amounts have been made to conform to the current period presentation. The Company eliminated the presentation of restaurant operating income (loss) as a non-GAAP measure from its consolidated condensed statements of operations. SEASONALITY — The Company has substantial fixed costs that do not decline proportionally with sales. The first and second fiscal quarters, which include the winter months, usually reflect lower customer traffic than in the third and fourth fiscal quarters. However, sales in the third and fourth fiscal quarters can be adversely affected by inclement weather due to the significant amount of outdoor seating at the Company’s restaurants. FAIR VALUE OF FINANCIAL INSTRUMENTS — The carrying amount of cash and cash equivalents, receivables, accounts payable and accrued expenses approximate fair value due to the immediate or short-term maturity of these financial instruments. The fair values of notes receivable and payable are determined using current applicable rates for similar instruments as of the balance sheet dates and approximate the carrying value of such debt instruments. CASH AND CASH EQUIVALENTS — Cash and cash equivalents include cash on hand, deposits with banks and highly liquid investments generally with original maturities of three months or less. Outstanding checks in excess of account balances, typically vendor payments, payroll and other contractual obligations disbursed after the last day of a reporting period are reported as a current liability in the accompanying consolidated condensed balance sheets. CONCENTRATIONS OF CREDIT RISK — Financial instruments that potentially subject the Company to concentrations of credit risk consist primarily of cash and cash equivalents and accounts receivable. The Company reduces credit risk by placing its cash and cash equivalents with major financial institutions with high credit ratings. At times, such amounts may exceed Federally insured limits. Accounts receivable are primarily comprised of normal business receivables, such as credit card receivables, that are collected in a short period of time and amounts due from the hotel operators where the Company has a location, and are recorded upon satisfaction of the performance obligation. The Company reviews the collectability of its receivables on an ongoing basis, and provides for an allowance when it considers the entity unable to meet its obligation. The concentration of credit risk with respect to accounts receivable is generally limited due to the short payment terms extended by the Company and the number of customers comprising the Company’s customer base. As of March 28, 2020 , the Company had accounts receivable balances due from three hotel operators totaling 88% of total accounts receivable. As of September 28, 2019 , the Company had accounts receivable balances due from one hotel operator totaling 34% of total accounts receivable. For the 13-week period ended March 28, 2020 , the Company made purchases from two vendors that accounted for 20% of total purchases. For the 13-week period ended March 30, 2019 , the Company did no t make purchases from any one vendor that accounted for 10% or greater of total purchases. For the 26-week periods ended March 28, 2020 and March 30, 2019 , the Company did no t make purchases from any one vendor that accounted for 10% or greater of total purchases for the respective period. As of March 28, 2020 and December 28, 2019 , all debt outstanding is with one lender (see Note 7 – Notes Payable – Bank). GOODWILL AND TRADEMARKS - Goodwill and trademarks are not amortized, but are subject to impairment analysis. We assess the potential impairment of goodwill and trademarks annually (at the end of our fourth quarter) and on an interim basis whenever events or changes in circumstances indicate that the carrying value may not be recoverable. If we determine through the impairment review process that goodwill or trademarks are impaired, we record an impairment charge in our consolidated condensed statements of operations. Due to the recent impact of the COVID-19 pandemic to the global economy, including but not limited to, the volatility of the Company's stock price, temporary closure of the Company's restaurants and the challenging environment for the restaurant industry in general, the Company determined that there were indicators of potential impairment of its goodwill and trademarks during the 13 weeks ended March 28, 2020. As such, the Company performed a qualitative assessment for both goodwill and its trademarks and concluded that the fair value of these assets exceeded their carrying values. Accordingly, the Company did not record any impairment to its goodwill or trademarks during the 13 and 26 weeks ended March 28, 2020. The ultimate severity and longevity of the COVID-19 pandemic is unknown, and therefore, it is possible that impairments could be identified in future periods, and such amounts could be material. LONG-LIVED AND RIGHT-OF-USE ASSETS - Long-lived assets, such as property, plant and equipment, purchased intangibles subject to amortization, and right-of-use assets ("ROU assets") are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. In the evaluation of the fair value and future benefits of long-lived assets, the Company performs an analysis of the anticipated undiscounted future net cash flows of the related long-lived assets. If the carrying value of the related asset exceeds the undiscounted cash flows, the carrying value is reduced to its fair value. Various factors including estimated future sales growth and estimated profit margins are included in this analysis. The Company considers a triggering event related to long-lived assets or ROU assets in a net asset position to have occurred related to a specific restaurant if the restaurant’s cash flows for the last twelve months are less than a minimum threshold or if consistent levels of undiscounted cash flows for the remaining lease period are less than the carrying value of the restaurant’s assets. Additionally, the Company considers a triggering event related to ROU assets to have occurred related to a specific lease if the location has been subleased and future estimated sublease income is less than current lease payments. If the Company concludes that the carrying value of certain long-lived and ROU assets will not be recovered based on expected undiscounted future cash flows, an impairment loss is recorded to reduce the long-lived or ROU assets to their estimated fair value. The fair value is measured on a nonrecurring basis using unobservable (Level 3) inputs. There is uncertainty in the projected undiscounted future cash flows used in the Company's impairment review analysis, which requires the use of estimates and assumptions. If actual performance does not achieve the projections, or if the assumptions used change in the future, the Company may be required to recognize impairment charges in future periods, and such charges could be material. Based on the results of this analysis, the Company recognized an impairment charge of $364,000 related to long-lived assets and ROU assets during the 13 and 26 weeks ended March 28, 2020 (see Note 4 – Recent Restaurant Dispositions). Given the inherent uncertainty in projecting results of restaurants under the current circumstances, particularly taking into account the projected impact of the COVID-19 pandemic, the Company is monitoring the recoverability of the carrying value of the assets of several restaurants on an ongoing basis. For these restaurants, if expected performance is not realized, an impairment charge may be recognized in future periods, and such charge could be material. REVENUE RECOGNITION — We recognize revenues when it satisfies a performance obligation by transferring control over a product or service to a restaurant guest or other customer. Revenues from restaurant operations are presented net of discounts, coupons, employee meals and complimentary meals and recognized when food, beverage and retail products are sold. Sales tax collected from customers is excluded from sales and the obligation is included in sales tax payable until the taxes are remitted to the appropriate taxing authorities. Catering service revenue is generated through contracts with customers whereby the customer agrees to pay a contract rate for the service. Revenues from catered events are recognized in income upon satisfaction of the performance obligation (the date the event is held) and all customer payments, including nonrefundable upfront deposits, are deferred as a contract liability until such time. We recognized $1,552,000 and $1,652,000 in catering services revenue for the 13-week periods ended March 28, 2020 and March 30, 2019 , respectively, and $7,234,000 and $7,482,000 for the 26-week periods ended March 28, 2020 and March 30, 2019, respectively. Unearned revenue, which is included in accrued expenses and other current liabilities on the consolidated condensed balance sheets as of March 28, 2020 and September 28, 2019 , was $3,923,000 and $4,549,000 , respectively. LEASES — We determine if an arrangement contains a lease at inception. An arrangement contains a lease if it implicitly or explicitly identifies an asset to be used and conveys the right to control the use of the identified asset in exchange for consideration. As a lessee, we include operating leases in Operating lease right-of-use assets and Operating lease liabilities in our consolidated condensed balance sheet. Right-of-use assets represent our right to use an underlying asset for the lease term and lease liabilities represent our obligation to make lease payments arising from the lease. Operating lease right-of-use assets and liabilities are recognized upon commencement of the lease based on the present value of the lease payments over the lease term. As most of our leases do not provide an implicit interest rate, we use our incremental borrowing rate based on the information available at commencement date to determine the present value of lease payments. Our lease terms may include options to extend or terminate the lease. Options are included when it is reasonably certain that we will exercise that option. Lease expense for lease payments is recognized on a straight-line basis over the lease term. Leases with a lease term of 12 months or less are accounted for using the practical expedient which allows for straight-line rent expense over the remaining term of the lease. SEGMENT REPORTING — As of March 28, 2020 , the Company owned and operated 20 restaurants and bars, 17 fast food concepts and catering operations, exclusively in the United States, that have similar economic characteristics, nature of products and services, class of customers and distribution methods. The Company believes it meets the criteria for aggregating its operating segments into a single reporting segment in accordance with applicable accounting guidance. RECENTLY ADOPTED ACCOUNTING PRINCIPLES — In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842), which amends the existing accounting standards for lease accounting, including requiring lessees to recognize assets and liabilities for leases with lease terms of more than twelve months. The new guidance also requires additional disclosures about leases. The Company adopted the new standard on September 29, 2019 (the first day of fiscal year 2020) using the modified retrospective approach, without restating comparative periods for those lease contracts for which we have taken possession of the property as of September 28, 2019. Accordingly, prior period amounts were not revised and continue to be reported in accordance with ASC Topic 840 (“ASC 840”), the accounting standard then in effect. As part of our adoption we elected the "package of practical expedients", as well as the hindsight practical expedient, permitted under the new guidance, which, among other things, allowed the Company to continue utilizing historical classifications of leases as well as allowing us to combine lease and non-lease components of our real estate leases. We also elected to adopt the short-term lease exception for all leases with terms of twelve months or less and account for them using straight-line rent expense over the remaining life of the lease. As a result of the adoption of this guidance, we recorded ROU assets of $62,330,000 and lease liabilities related to our real estate operating leases of $63,943,000 . The adoption of this standard did not materially impact retained earnings or our consolidated condensed statement of operations and had no impact on cash flows. In June 2018, the FASB issued ASU 2018-07, Compensation - Stock Compensation (Topic 718): Improvements to Non-employee Share-Based Payment Accounting, which simplifies the accounting for share-based payments granted to non-employees for goods and services. Under this ASU, the guidance on share-based payments to non-employees would be aligned with the requirements for share-based payments granted to employees, with certain exceptions. The Company adopted this guidance in the first quarter of fiscal 2020. Such adoption did not have a material impact on our consolidated condensed financial statements. NEW ACCOUNTING STANDARDS NOT YET ADOPTED — In December 2019, the FASB issued ASU No. 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes, which modifies Topic 740 to simplify the accounting for income taxes. ASU 2019-12 is effective for financial statements issued for annual periods beginning after December 15, 2020, and for the interim periods therein. The Company is currently evaluating the effect of adopting ASU 2019-12 to determine the impact on the Company’s consolidated financial position and results of operations. |
