Accordingly, they do not include all of the information and footnotes required by accounting principles generally accepted in the United States of America for complete financial statements. In our opinion, all adjustments (consisting only of normal recurring accruals) considered necessary for a fair presentation have been included. Operating results for the nine-month period ended June 29, 2013 are not necessarily indicative of the results that may be expected for the fiscal year ending September 28, 2013. For further information, refer to our Annual Report on Form 10-K for the fiscal year ended September 29, 2012. Principles of Consolidation The consolidated financial statements include the accounts of the Company and Span Medical Products Canada Inc., a British Columbia corporation (“Span-Canada”), its wholly-owned subsidiary. Significant inter-company accounts and transactions have been eliminated. Foreign Currency Translation The assets and liabilities of Span-Canada, operating under the name “M.C. Healthcare Products,” which uses the Canadian dollar as its functional currency, are translated into U.S. dollars at the quarter-end exchange rate. Revenues and expenses are translated at weighted average exchange rates. The resulting translation adjustments are recorded as a separate component of shareholders’ equity. Recently Issued Accounting Standards Accounting standards that have been issued or proposed by the Financial Accounting Standards Board (“FASB”) or other standards-setting bodies that do not require adoption until a future date are not expected to have a material impact on our financial statements upon adoption. Stock-Based Compensation We measure and recognize compensation expense for all stock-based payments at fair value. Stock-based payments include stock option grants. We have granted options to purchase common stock to some of our employees under various plans at prices equal to the market value of the stock on the dates the options were granted. New shares of stock are issued upon share option exercise. We do not have treasury stock. The fair value of each option grant is estimated on the date of grant using the Black-Scholes option pricing model with the following weighted average assumptions for grants made in fiscal 2011: risk-free interest rate of 2.54%; dividend yield of 2.5%; volatility factor of the expected market price of our common stock of 43.02%; and a weighted average expected life of the options of 9.0 years. No options were granted during the nine months ended June 29, 2013 or during fiscal year 2012. falsefalsefalsenonnum:textBlockItemTypenaThe entire disclosure for all significant accounting policies of the reporting entity.Reference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher FASB -Name Accounting Standards Codification -Topic 235 -SubTopic 10 -Section 50 -Paragraph 3 -URI http://asc.fasb.org/extlink&oid=6367646&loc=d3e18780-107790 Reference 2: http://www.xbrl.org/2003/role/presentationRef -Publisher FASB -Name Accounting Standards Codification -Topic 235 -SubTopic 10 -Section 50 -Paragraph 1 -URI http://asc.fasb.org/extlink&oid=6367646&loc=d3e18726-107790 Reference 3: http://www.xbrl.org/2003/role/presentationRef -Publisher FASB -Name Accounting Standards Codification -Topic 235 -SubTopic 10 -Section 50 -Paragraph 6 -URI http://asc.fasb.org/extlink&oid=6367646&loc=d3e18861-107790 Reference 4: http://www.xbrl.org/2003/role/presentationRef -Publisher FASB -Name Accounting Standards Codification -Topic 235 -SubTopic 10 -Section 50 -Paragraph 2 -URI http://asc.fasb.org/extlink&oid=6367646&loc=d3e18743-107790 Reference 5: http://www.xbrl.org/2003/role/presentationRef -Publisher FASB -Name Accounting Standards Codification -Topic 235 -SubTopic 10 -Section 50 -Paragraph 5 -URI http://asc.fasb.org/extlink&oid=6367646&loc=d3e18854-107790 false0Significant Accounting Policies [Text Block]falseNote 1 - Significant Accounting PoliciesUnKnownUnKnownUnKnownUnKnowntruefalsefalseSheethttp://www.spanamerica.com/role/Note1SignificantAccountingPolicies12
