## Abstract

The Federal Communications Commission, on its own motion, clarifies certain aspects of the Implementation of the Commercial Spectrum Enhancement Act and Modernization of the Commission's Competitive Bidding Rules and Procedures. Among other things, the Commission clarifies that the expansion of the unjust enrichment payment schedule to ten years applies only to licenses granted on or after April 25, 2006. This ensures that retroactive penalties are not imposed on pre-existing designated entities.
