April 10 is the comment deadline for a Securities and Exchange Commission (SEC) proposal to require more detailed reporting of top executive compensation, including such perks as personal use of corporate aircraft. One of the proposals would lower the threshold at which perks must be disclosed. Companies currently must reveal perks if the total aggregate value is more than $50,000, or 10 percent of total annual salary and bonus. The proposal lowers the threshold to $10,000. To see the proposal and to submit comments, go to www.sec.gov.
