        <ExplanationTxt>Internet2's grants management is guided to a large extent by compliance with OMB requirements governing a broad range of cost-accounting issues, including budget management and amendment, expenditure monitoring and reporting, cost transfers, oversight of allowable and unallowable costs, and other issues that are all auditable and reportable. These are subject to annual review through the audit process and informed by regular updates from agencies, Uniform Guidance, and Federal Demonstration Project compliance measures. Our cost-accounting standards for monitoring use of grant funds in the United States include monthly review of allowable/unallowable costs; budget and expenditure analysis; cost transfers and expenditure classification if necessary; documentation of expenditure review and approval; regular review and application of standards for reasonableness, allocability, and allowability of costs; regular review and updates of policies and procedures for unallowable costs; and application of standards for micro-purchase and simplified acquisitions.</ExplanationTxt>

        <ExplanationTxt>The process for determining compensation of the organization's CEO, Officers and some key employees is led by the Board's Compensation Committee; the members of the Board involved on this committee are all outside members. The Corporate Secretary and/or HR department periodically conducts a salary benchmarking study for each position based on duties, industry, and area of the country and provides the findings to the Board Compensation Committee Chair. The CEO and other top executives have established goals for each year. A formal review of those goals is conducted annually, by the Board for the CEO and by the CEO for the other executives. This part of the process identifies another factor for determining appropriate pay changes, in addition to the salary benchmarking data. The Compensation Committee makes compensation decisions for the CEO and reports the details to the Corporate Secretary and/or the HR department. The CEO provides recommended compensation for the other executives, which must be approved by the Compensation Committee. The committee provides their response to the CEO, who then informs the HR department. These written approvals are obtained prior to implementing any compensation changes.</ExplanationTxt>
