        <ExplanationTxt>APS is exempt from federal income tax under Section 501(c)(3) of the Internal Revenue Code and has been classified as an organization that is not a private foundation. APS had an immaterial amount of unrelated business income for the years ended December 31, 2015 and 2014. Under ASC 740-10, Accounting for Uncertainty in Income Taxes, an organization must recognize the tax benefit associated with tax positions taken for tax return purposes when it is more-likely than not that the position will be sustained. APS does not believe there are any material uncertain tax positions and; accordingly, will not recognize any liability for unrecognized tax benefits. APS has filed for and received income tax exemptions in the jurisdictions where it is required to do so. Additionally, APS has filed Internal Revenue Form 990 tax returns as required and all applicable returns in those jurisdictions where it is required. APS believes that it is no longer subject to U.S. federal, state and local, or non-U.S. income tax examinations by tax authorities for years before 2012. However, APS is still open to examinations by tax authorities from fiscal year 2012 forward. For the years ended December 31, 2015 and 2014, there were no interest or penalties recorded in the statements of activities.</ExplanationTxt>

        <ExplanationTxt>Recipients are selected based upon criteria determined by oversight committees. Recipients provided lump sum payments at the beginning of the grant period are expected to submit final reports detailing expenditures. Funds given on a "reimbursement" basis require the recipient to provide APS with an expense report that includes receipts for his/her expenditures. In addition, the formal Prize and Awards are based upon prior accomplishments and are approved by the Council of Representatives before being given to distinguished physicists.</ExplanationTxt>

        <ExplanationTxt>Recipients are selected based upon criteria determined by oversight committees. Recipients provided lump sum payments at the beginning of the grant period are expected to submit final reports detailing expenditures. Funds given on a "reimbursement" basis require the recipient to provide APS with an expense report that includes receipts for his/her expenditures. In addition, the formal Prizes and Awards are based upon prior accomplishments and are approved by the Council of Representatives before being given to distinguished physicists.</ExplanationTxt>
