Condensed Consolidated Financial Statements [Abstract]
Revisions And Reclassifications	Revisions and Reclassifications We have evaluated the principal vs. agent accounting guidance in assessing the appropriate presentation for certain transactions primarily related to our fiscal 2017 acquisitions. We have determined agent accounting is appropriate for such transactions and therefore concluded that amounts previously presented on a gross basis should have been recorded on a net basis. Accordingly, we have revised amounts previously recorded in connection with these transactions during the first and second quarters of fiscal 2017. The revisions resulted in a reduction of sales and cost of sales by equal amounts of $1.6 million and $2.7 million for the first and second quarters of fiscal 2017, respectively. These revisions were not material to any prior period financial statements and did not impact gross profit as previously reported. Certain amounts in these financial statements have been reclassified to maintain comparability among the periods presented.
Recent Accounting Pronouncements	Recent Accounting Pronouncements In May 2014, the Financial Accounting Standards Board (“FASB”) issued new accounting guidance for the reporting of revenue from contracts with customers. This guidance provides guidelines a company will apply to determine the measurement of revenue and timing of when it is recognized. Additional guidance has subsequently been issued to amend or clarify the reporting of revenue from contracts with customers. The guidance is effective for fiscal years and interim periods within those years beginning after December 15, 2017. Early adoption is permitted, but not before the original effective date of December 15, 2016. We are currently evaluating the potential effect of the adoption of this guidance on our Consolidated Financial Statements. In August 2014, the FASB issued new accounting guidance for the disclosure of an entity’s ability to continue as a going concern. This guidance establishes specific guidelines to an organization’s management on their responsibility to evaluate whether there is substantial doubt about the organization’s ability to continue as a going concern. This guidance is effective for fiscal years ending after December 15, 2016, and interim periods thereafter. This guidance is not expected to have an impact on our Consolidated Financial Statements. In February 2016, the FASB issued new accounting guidance related to leases. This guidance establishes a right of use (“ROU”) model that requires a lessee to record a ROU asset and lease liability on the balance sheet for all leases with terms longer than twelve months. Leases will be classified as either finance or operating, with classification affecting the pattern of expense recognition. The guidance is effective for financial statements issued for fiscal years beginning after December 15, 2018 and interim periods within those fiscal years. A modified retrospective transition approach is required for lessees for capital and operating leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements, with certain practical expedients available. Early adoption is permitted. We are currently evaluating the potential impact of the adoption of this guidance on our Consolidated Financial Statements. In March 2016, the FASB issued new accounting guidance intended to simplify various aspects related to accounting for share-based payments and their presentation in the financial statements. This guidance is effective for fiscal years and interim periods within those years beginning after December 15, 2016. Early adoption is permitted. We are currently evaluating the potential impact of the adoption of this guidance on our Consolidated Financial Statements. In August 2016, the FASB issued new accounting guidance related to cash flow classification. This guidance clarifies and provides specific guidance on eight cash flow classification issues that are not addressed by current GAAP and thereby reduce the current diversity in practice. This guidance is effective for fiscal years and interim periods within those years beginning after December 15, 2017. Early adoption is permitted. We are currently evaluating the potential impact of the adoption of this guidance on our Consolidated Financial Statements. In October 2016, the FASB issued new accounting guidance related to the income tax consequences of an intra-entity transfer of an asset other than inventory. This guidance will require that entities recognize the income tax consequences of an intra-entity transfer of an asset other than inventory when the transfer occurs instead of when the asset is sold. This guidance is effective for fiscal years and interim periods within those years beginning after December 15, 2017. Early adoption is permitted. This guidance is not expected to have an impact on our Consolidated Financial Statements. In November 2016, the FASB issued new accounting guidance to clarify how entities should present restricted cash and restricted cash equivalents in the statement of cash flows. This guidance will require that entities show the changes in the total of cash, cash equivalents, restricted cash and restricted cash equivalents in the statement of cash flows. This guidance is effective for fiscal years and interim periods within those years beginning after December 15, 2017. Early adoption is permitted. This guidance is not expected to have an impact on our Consolidated Financial Statements. Other recent authoritative guidance issued by the FASB (including technical corrections to the Accounting Standards Codification) and the Securities and Exchange Commission did not, or are not expected to have a material effect on Monro’s Consolidated Financial Statements.
Guarantees	Guarantees At the time we issue a guarantee, we recognize an initial liability for the fair value, or market value, of the obligation we assume under that guarantee. Monro has guaranteed certain lease payments, primarily related to franchisees, amounting to $8.5 million. This amount represents the maximum potential amount of future payments under the guarantees as of December 24, 2016. The leases are guaranteed through April 2020. In the event of default by the franchise owner, Monro generally retains the right to assume the lease of the related store, enabling Monro to re-franchise the location or to operate that location as a Company-operated store. We have recorded a liability related to anticipated defaults under the foregoing leases of $.7 million and $.4 million as of December 24, 2016 and December 26, 2015, respectively.
