        <ExplanationTxt>Each January, the Board of Directors are asked to review and sign the Conflict-of-Interest Policy. At all meetings it is normal practice for a member to leave the room if there is a perceived conflict of interest. Accounting reviews transactions with any of our related parties and questions any transaction that may appear to be a conflict of interest. The CFO and the Board of Directors determine if it is a true conflict. If it were to occur, there would be a recusal from any related voting activity on the Board of Directors. SPIE also complies with all proper transparency requirements that are applicable.</ExplanationTxt>

        <ExplanationTxt>Executive staff: Each year, the Compensation Committee utilized 4-6 salary surveys to benchmark compensation for the following roles: *Chief Executive Officer* Chief Operating &amp; Financial Officer* Chief Technology Officer* Chief Engagement Officer* Sr. Director of Events and Exhibitions* Sr. Director of Science, Technology &amp; Industry Programs* Sr. Direct of Publications. These surveys provide comparative compensation data from the industrial, not-for-profit, and local job markets. To support this process, the Compensation Committee engages a compensation consultant at least once every three years to assist in developing recommendations. The resulting market data is reviewed by the Committee to determine an appropriate salary for the Chief Executive Officer. For the remaining positions, the comparison data is provided to the Chief Executive Officer, who then makes compensation recommendations to the Compensation Committee. These recommendations are reivewed and approved by the Committee and subsequently reported to the Executive Committee. Director staff: Twice a year, we review salary data from various regional and nonprofit surveys to see how our director-level roles compare to the market. A third-party compensation analyst then uses this data to calculate how much our salary ranges should shift and updates the minimum, midpoint, and maximum accordingly. The analyst also recommends any needed changes to job grades or the overall pay structure. These updates, along with performance reviews, help guide pay decisions for directors. Senior Directors suggest merit increases, which are then reviewed by the CEO.
