Nature Of Business And Significant Accounting Policies [Text Block] | (1) Basis of Presentation Basis of Presentation Famous Dave’s of America, Inc. (“Famous Dave’s” or the “Company”) was incorporated in Minnesota on March 14, 1994. The Company develops, owns, operates and franchises restaurants under the name "Famous Dave’s." As of March 31, 2019, there were 138 Famous Dave’s restaurants operating in 33 states, the Commonwealth of Puerto Rico, Canada, and the United Arab Emirates, including 21 Company-owned restaurants and 117 franchise-operated restaurants. These consolidated financial statements were prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) and Securities and Exchange Commission (“SEC”) Rules and Regulations. These unaudited consolidated financial statements represent the consolidated financial statements of the Company and its subsidiaries as of March 31, 2019 and December 30, 2018, and for the three months ended March 31, 2019 and April 1, 2018. The information furnished in these consolidated financial statements includes normal recurring adjustments and reflects all adjustments, which are, in the opinion of management, necessary for a fair presentation. Certain information and footnote disclosures normally included in financial statements prepared in accordance with GAAP have been condensed or omitted. These consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 30, 2018 as filed with the SEC on March 4, 2019. Due to the seasonality of the Company’s business, revenue and operating results for the three months ended March 31, 2019 are not necessarily indicative of the results to be expected for the full fiscal year or any other interim period. Reclassifications Certain prior period amounts have been reclassified to conform to the current period’s presentation. These reclassifications did not have an impact on the reported net income for any of the periods presented. Income Taxes The Company maintains a federal deferred tax asset (“DTA”) in the amount of $5.8 million for each of the periods ended March 31, 2019 and December 30, 2018. The Company evaluates the DTA on a quarterly basis to determine whether current facts and circumstances indicate that the DTA may not be fully realizable. As of March 31, 2019, the Company concluded that the DTA is fully realizable and that a valuation allowance was not considered necessary; however, the Company will continue to evaluate the asset on a quarterly basis until the DTA has been fully utilized. The following table presents the Company’s effective tax rates for the periods presented: Three Months Ended March 31, 2019 April 1, 2018 Effective tax rate 17.2 % 24.3 % The Company provides for income taxes based on its estimate of federal and state income tax liabilities. These estimates include, among other items, effective rates for state and local income taxes, allowable tax credits for items such as taxes paid on reported tip income, estimates related to depreciation and amortization expense allowable for tax purposes, and the tax deductibility of certain other items. The Company’s estimates are based on the information available at the time that the Company prepares the income tax provision. The Company generally files its annual income tax returns several months after its fiscal year-end. Income tax returns are subject to audit by federal, state, and local governments, generally years after the tax returns are filed. These returns could be subject to material adjustments or differing interpretations of the tax laws. Restricted cash and marketing fund The Company has a system-wide marketing development fund, to which Company-owned restaurants, in addition to the majority of franchise-operated restaurants, contribute a percentage of net sales for use in public relations and marketing development efforts. The assets held by this fund are considered to be restricted. Accordingly, the Company reflects the cash related to this fund within restricted cash and reflects the liability within accounts payable on the Company’s consolidated balance sheets. The Company had approximately $697,000 and $700,000 in this fund as of March 31, 2019 and December 30, 2018, respectively. In conjunction with the Company’s credit agreements, the Company has deposited amounts for undrawn letters of credit in cash collateral accounts. The Company had approximately $143,000 and $143,000 in restricted cash as of March 31, 2019 and December 30, 2018, respectively, related to these undrawn letters of credit. Concentrations of Credit Risk Recently Adopted Accounting Pronouncements In June 2018, the FASB issued ASU 2018-07, Compensation-Stock Compensation (Topic 718), which expands the scope of Topic 718 to include share-based payment transactions for acquiring goods and services from nonemployees. Under the updated standard, an entity is required to apply the requirements of Topic 718 to nonemployee awards, except for specific guidance on inputs to an option-pricing model and the attribution of cost. The amendments specify that Topic 718 applies to all share-based payment transactions in which a grantor acquires goods or services to be used or consumed in the grantor’s own operations by issuing share-based payment awards. The amendments also clarify that Topic 718 does not apply to share-based payments used to effectively provide (1) financing to the issuer or (2) awards granted in conjunction with selling or goods or services as part of a contract accounted for under Topic 606, Revenue from Contracts with Customers. The amendments in this ASU are effective for fiscal years beginning after December 15, 2018 and interim periods within that fiscal year. Early adoption was permitted, but no earlier than an entity’s adoption date of Topic 606. The Company adopted this new standard as of the effective date. Adoption of the new standard did not have a material impact on the Company’s consolidated financial statements. Beginning in fiscal 2019, the Company adopted Topic 842, Leases, which had a material impact on the Company’s consolidated financial statements. See Note 7 – Leases. |
