USE OF ENDOWMENT FUNDS	FORM 990, SCHEDULE D, PART V, LINE 4 EARNINGS FROM THE ENDOWMENT ARE USED TO FURTHER THE EXEMPT PURPOSES OF THE ORGANIZATION.
LIABILITY FOR UNCERTAIN TAX POSITION	FORM 990, SCHEDULE D, PART X, LINE 2 NAS follows guidance that clarifies the accounting for uncertainty in tax positions taken or expected to be taken in a tax return, including issues relating to financial statement recognition and measurement. This guidance provides that the tax effects from an uncertain tax position can only be recognized in the financial statements if the position is "more-likely-than-not" to be sustained if the position were to be challenged by a taxing authority. The assessment of the tax position is based solely on the technical merits of the position, without regard to the likelihood that the tax position may be challenged. NAS is exempt from federal income tax under Internal Revenue Code ("IRC") Section 501(c)(3), though it is subject to tax on income unrelated to its exempt purpose, unless that income is otherwise excluded by the IRC. NAS has processes presently in place to maintain its tax-exempt status; to identify and report unrelated income; to determine its filing and tax obligations in jurisdictions for which it may have a nexus; and to identify and evaluate other matters that may be considered tax positions. The tax years ending December 31, 2019, 2018, 2017, and 2016 are still open to audit for both federal and state income tax purposes. NAS has determined that there are no material unrelated business activities or uncertain tax positions that require recognition or disclosure in the financial statements.
