Summary of Accounting Policies
Summary of Accounting Policies	1. Summary of Accounting Policies The summary of the Issuer’s significant accounting policies are incorporated by reference to the Company’s annual report on Form 10-K, at March 31, 2011. The accompanying unaudited condensed financial statements have been prepared in accordance with accounting principles for interim financial information and with the instructions to Form 10-Q and reflect all adjustments which, in the opinion of management, are necessary for a fair presentation of the results of operations, financial position and cash flows.  The results of the interim period are not necessarily indicative of the results for the full year. Recently Adopted Accounting Pronouncements In January 2010, the FASB updated the disclosure requirements for fair value measurements, codified in ASC Topic 820, Fair Value Measurements and Disclosure.  The updated guidance requires companies to disclose separately the investments that transfer in and out of Levels 1 and 2 and the reasons for those transfers. Additionally, in the reconciliation for fair value measurement using significant unobservable inputs (Level 3), companies should present separately information about purchases, sales, issuances and settlements.  We adopted the updated guidance on April 1, 2010, except for the disclosures about purchases, sales, issuances and settlements in the Level 3 reconciliation, which became effective for us beginning April 1, 2011.  The adoption of the required guidance did not have an impact on our financial statements. In July 2010, FASB issued a new pronouncement that requires enhanced disclosures regarding the nature of credit risk inherent in an entity’s portfolio of financing receivables, how that risk is analyzed, and the changes and reasons for those changes in the allowance for credit losses. The new disclosures will require information for both the financing receivables and the related allowance for credit losses at more disaggregated levels. Disclosures related to information as of the end of a reporting period became effective for Mesa in the fourth quarter of Fiscal 2011. Specific disclosures regarding activities that occur during a reporting period, such as the disaggregated roll forward disclosures, became required for Mesa beginning in the first quarter of Fiscal 2012. As these changes only relate to disclosures, they did not have an impact on Mesa’s consolidated financial results.
