Additional information regarding federal government technical programs is available by searching for Southwest Research Institute's single audit at http://harvester.census.gov/facdissem/. As a nonprofit research and development organization, SwRI invests in innovation, using our robust internal research and development (IR&amp;D) program to expand and enhance our expertise and encourage our staff's professional growth. In 2024, SwRI initiated 119 IR&amp;D new projects, investing more than $11 million in internal research, including quick-look and focused research programs.

Through internal research, we increase our technical capabilities, expand our reputation as a leader in science and technology, and invest in technology our clients may need in the future. The program also allows engineers and scientists to grow in their technical fields by providing freedom to explore innovative and unproven concepts. Internal Research Projects for 2024 are described at https://www.swri.org/newsroom/annual-report/2024/2024-annual-report.</Desc>

        <ExplanationTxt>First class or charter travel: The Institute's travel policy generally does not permit first class or charter travel. There are a small number of exceptions for approved medical accomodations or other business required special circumstances. Tax indemnification and gross-up payments: SwRI provided additional cash compensation (reported on the W-2 and Schedule J) to partially offset the economic impact of a grandfathered taxable benefit to one officer. This represents .24% of total officer compensation. Health or social club dues/fees: SwRI reimburses the membership cost for one officer at a social club. The personal portion is included in compensation and any charges related to personal use are paid by the officer.</ExplanationTxt>

        <ExplanationTxt>Determination of Compensation: SwRI's strategy is to provide compensation that is fair, reasonable, and consistent with compensation paid for similar work in relevant labor areas and with compensation paid by Institute competitors in the markets for scientific research and development (R&amp;D) and other technical services. The principal compensation authority is vested with the Board of Directors; however, the President of the Institute retains the authority to determine how various programs will be structured and administered subject to the oversight of the Compensation Committee of the Board of Directors. The Committee uses reputable compensation survey data, gathered annually, to compare the compensation of Officers to peer groups, within the relevant market segments, targeting an appropriate percentile corresponding to performance both for the year in question, and considering longer-term performance trends for total compensation. This review shall include comparative analysis of compensation paid by the Institute to compensation paid by local, sector, and national applied research and development organizations of similar size, both for profit and nonprofit organizations. The Committee engages the services of an external compensation advisor when conducting such comparability studies. Compensation Committee Review and Approval: The Board of Director delegates to the Committee the responsibility, in consultation with the President to review, approve and inform the Board of Directors of the changes in annual compensation and benefits for all Officers, except the President and Executive Vice President. The Committee will review the performance of the President and Executive Vice President and make a recommendation to the Board of Director for the total compensation for both of these officers. Adequate documentation is created contemporaneously and maintained to substantiate the basis for the Committee's and the Board of Directors' determination of total compensation for the President and all other Officers.</ExplanationTxt>
