Description of New Accounting Pronouncements Not yet Adopted [Text Block]	NOTE B – RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS NOT YET ADOPTED In April 2014, the Financial Accounting Standards Board (“FASB”) issued new accounting guidance changing the criteria for reporting discontinued operations. The revised definition of a discontinued operation includes those components of an entity or a group of components of an entity representing a strategic shift that has (or will have) a major effect on an entity’s operations and financial results. The guidance eliminates the current requirement to assess continuing cash flow and continuing involvement with the disposal group. The revised definition also includes a business or nonprofit activity that, on acquisition, meets the criteria to be classified as held for sale. A disposal meeting the new definition is required to be reported as discontinued operations when the component of an entity or group of components of an entity meets the held for sale criteria, is actually disposed of by sales, or is disposed of through means other than a sale. The guidance is effective for Nathan’s for annual periods beginning on or after December 15, 2014 and interim periods within those years, which for Nathan’s will be the first quarter of fiscal 2016 beginning on March 30, 2015. Early adoption is permitted for disposals that have not been previously reported in the financial statements. Nathan’s does not expect the adoption of this new guidance to have a material impact on its results of operations or financial position. In May 2014, the FASB issued a new accounting standard that attempts to establish a uniform basis for recording income to virtually all industries financial statements, under U.S. GAAP. The revenue standard’s core principle is built on the contract between a vendor and a customer for the provision of goods and services. It attempts to depict the exchange of rights and obligations between the parties in the pattern of revenue recognition based on the consideration to which the vendor is entitled. In order to accomplish this objective, companies must evaluate the following five basic steps: (i) identify the contract with the customer, (ii) identify the performance obligations in the contract, (iii) determine the transaction price, (iv) allocate the transaction price to the performance obligations in the contract, and (v) recognize revenue when (or as) the entity satisfies a performance obligation. There are three basic transition methods that are available – full retrospective, retrospective with certain practical expedients, and a cumulative effect approach. Under the third alternative, an entity would apply the new revenue standard only to contracts that are incomplete under legacy U.S. GAAP at the date of initial application and recognize the cumulative effect of the new standard as an adjustment to the opening balance of retained earnings. Prior years would not be restated and additional disclosures would be required to enable users of the financial statements to understand the impact of adopting the new standard in the current year compared to prior years that are presented under legacy U.S. GAAP. Early adoption is prohibited under U.S. GAAP. Public companies must apply the new standard for annual periods beginning after December 15, 2016, including interim periods therein, which for Nathan’s will be its first fiscal quarter ending June 25, 2017. The Company has not yet selected a transition method and is currently evaluating the impact of this new accounting standard on its consolidated financial position and results of operations. In August 2014, the FASB issued new guidance that requires management to evaluate whether there are conditions or events, considered in the aggregate, that raise substantial doubt about the entity’s ability to continue as a going concern within one year after the date that the financial statements are issued. If such conditions exist, management will be required to include disclosures enabling users to understand those conditions and management’s plans to alleviate or mitigate those conditions. This new standard is effective for annual periods ending after December 15, 2016 and interim periods within annual periods beginning after December 16, 2016. This standard will take effect in Nathan’s fourth quarter of our fiscal year ending March 26, 2017.
