[Code of Federal Regulations] [Title 5, Volume 2, Parts 700 to 1199] [Revised as of January 1, 2001] From the U.S. Government Printing Office via GPO Access [CITE: 5CFR841.405] [Page 249] TITLE 5--ADMINISTRATIVE PERSONNEL CHAPTER I--OFFICE OF PERSONNEL MANAGEMENT (Continued) PART 841--FEDERAL EMPLOYEES RETIREMENT SYSTEM--GENERAL ADMINISTRATION--Table of Contents Subpart D--Government Costs Sec. 841.405 Economic assumptions. The determinations of the normal cost percentage will be based on the economic assumptions determined by the Board. When an agency's case is based in whole or in part on the pattern of merit salary increases specific to the agency or to a category of employees within the agency, the Board may require modification of the economic assumptions concerning salary and wage growth to take into account the combined effect of merit and general wage and salary increases.
