Thousands of U.S. companies appear to have secretly backdated stock options. This Article analyzes three forms of secret option backdating: (1) the backdating of executives' option grants; (2) the backdating of nonexecutive employees' option grants; and (3) the backdating of executives' option exercises. It shows that each type of backdating less likely reflects arm's length contracting than a desire to inflate and camouflage executive pay. Secret backdating thus provides further evidence that pay arrangements have been shaped by executives' influence over their boards. The fact that so many firms continued to secretly backdate after the Sarbanes-Oxley Act, in blatant violation of its reporting requirements, also suggests recent reforms may have failed to adequately curb such managerial power.
