“The foundation has no employees, rather its program service, management, and fundraising are performed by the saint louis science center (a tax-exempt museum subdistrict of the state of missouri) which charges the foundation a management fee.

“Compensation of the president of the science center, who is also the president of the foundation, is reviewed and approved by an independent compensation committee of the science center and the board of directors of the foundation. They obtain and rely upon appropriate data for presidents of similar organizations of similar size, as provided by a compensation consultant, and document the basis for determining compensation in contemporaneously prepared documents and meeting minutes. For other key executives, compensation levels are determined using comparable salary data and input from the board of directors and members of the board of directors of the science center.”
