      <Desc>The Technology Advancement Center, Inc. (TAC) is a nonprofit 501(c)(4) entity chartered in the state of Maryland. TAC's facilities are a combination of state-of-the-art facilities, innovative programs, and imaginative people charged with finding that spark that leads to unparalleled capability for our partners. Through a partnership intermediary agreement (PIA) between TAC and USCYBERCOM, TAC enables USCYBERCOM and its partners to engage nontraditional partners to accelerate mission success. TAC has achieved success with projects advancing malware analysis, opensource threat intelligence sharing platforms, protecting against social media disinformation, computer vision, zero thrust network prototyping, and redesigning risk management frameworks. TAC evaluated commercial products to assess fit and feasibility for use within defined network parameters. TAC hosted five rapid prototyping events (RPES) to help identify and accelerate the path to violable solutions. TAC expanded its physical and virtual lab environments used for prototyping solutions, refining standard operating procedures in cyber defense operations, and skill development. TAC's innovation facilities are a choice location for organizations to hold strategic planning meetings or collaborations with partners as a nearby "offsite" with flexibility to accommodate in person meetings augmented with virtual platforms capabilities. TAC hosted in person, virtual, and hybrid events focused on increasing cyber security skills, capabilities, and awareness. TAC also built virtual collaboration platforms utilized to continue technical talks, demonstrations, and collaboration sessions during the pandemic. TAC's new capabilities were utilized by training organizations to create videos that spark interest and provide valuable resources to staff regardless of where they were now working and to host partners to bring a level of professionalism to their virtual participation. Similarly, TAC's facilities are a choice location for workforce development and outreach events. During 2022, TAC's internships provided high school and college students experience working side-by-side with subject matter experts solving real-world, mission-relevant technical challenges. TAC hosted programs specifically designed for students at minority serving institutions to help strengthen the nation's stem hiring pipeline.</Desc>

        <ExplanationTxt>The Organization evaluates uncertainty in income tax positions based on a more-likely-than-not recognition standard. If that threshold is met, the tax position is then measured at the largest amount that is greater than 50% likely of being realized upon ultimate settlement. As of December 31, 2023 and 2022, there are no accruals for uncertain tax positions. If applicable, the Organization records interest and penalties as a component of other expenses and are presented as management and general in the Statements of Activities and Changes in Net Assets and Functional Expenses. Tax years from 2020 through the current year remain open for examination by tax authorities.</ExplanationTxt>

        <ExplanationTxt>TAC hired a consulting firm to assist the board in determining reasonable compensation of the CEO and other officers, by obtaining data from comparable organizations for functionally comparable positions as reported on the Forms 990 from similar tax-exempt organizations located in the Maryland/DC/Virginia metro area. Mr. Gumtow recused himself from the board's consideration of his compensation as CEO. Upon analysis and in reliance on the data obtained, the board determined and approved the compensation arrangement for the CEO. TAC used the same process to determine the compensation of its chief information security officer, as it used for its CEO.</ExplanationTxt>
