| IRS990ScheduleD/SupplementalInformationDetail/ExplanationTxt | 0 | The Academy is exempt from federal and state income taxes under Internal Revenue Code 501(c)(3). The Academy is subject to tax on income from any unrelated business. On July 1, 2009, the Academy adopted the recognition requirements for uncertain income tax positions as required by the Financial Accounting Standards Board (FASB) ASC 740-10 (formerly known as FASB Interpretation No. 48, Accounting for Uncertainty in Income Taxes), with no cumulative effect adjustment required. Income tax benefits are recognized for income tax positions taken or expected to be taken in a tax return, only when it is determined that the income tax position will more likely-than-not be sustained upon examination by taxing authorities. The Academy has analyzed tax positions taken for filing with the Internal Revenue Service and state jurisdiction where they operate. The Academy believes that income tax filing positions will be sustained upon examination and do not anticipate any adjustments that would result in a material adverse affect on their respective financial condition, results of operation or cash flows. Accordingly, the Academy has not recorded any reserves, or related accruals for interest and penalties for uncertain income tax positions at June 30, 2018. |
