Benefits Administration Letter

 

Number: 13-302 Date: July 2013

Subject: Fiscal Year 2013 Cost Factors for Calculating Imputed Costs 

This Letter provides the fiscal year (FY) 2013 cost factors for the Federal civilian benefit 

programs. Agencies will use these factors to calculate their imputed costs relating to the Civil 

Service Retirement System (CSRS), the Federal Employees Retirement System (FERS), 

the Federal Employees Health Benefits Program (FEHB) and the Federal Employees’ Group 

Life Insurance Program (FEGLI). The imputed costs are used to determine the actuarial liabilities 

which are included in Governmental financial statements. 

Benefits Administration Letter (BAL) 03-309, dated September 15, 2003, provides detailed 

instructions for the computation and accounting for imputed costs related to the Federal civilian 

benefit programs; see http://www.opm.gov/retire/pubs/bals/2003/03-309.pdf for more information. 

COST FACTORS 

Pensions. The economic assumptions used to calculate the FY 2013 cost factors under Statement of 

Federal Financial Accounting Standard (SFFAS) 33: Pensions, Other Retirement Benefits, and 

Other Postemployment Benefits: Reporting the Gains and Losses from Changes in Assumptions and 

Selecting Discount Rates and Valuation Dates are based on 10-year historical averages. These 

economic assumptions differ from those established by OPM under guidance from the CSRS Board 

of Actuaries for the determination of certain statutory funding payments for CSRS and FERS. 

For most CSRS-covered employees, the FY 2013 cost factor is 32.3 percent of basic pay. The 

FY 2013 cost factors for all categories of CSRS coverage are attached. While agency payments 

under CSRS are not affected by the CSRS normal cost percentages for the vast majority of agencies, 

the CSRS normal cost percentages determined under SFFAS 33 are used to determine the actuarial 

liabilities which are included in Governmental financial statements. 

The FY 2013 cost factors reported in this BAL also differ from the normal cost percentages used to 

determine the employer contributions agencies pay for FERS employees. For most FERS-covered 

employees, the FY 2013 cost factor is 14.2 percent of basic pay. The cost factors for all categories of 

FERS coverage are attached. Since the cost factors reported under SFFAS 33 are determined on a 

different basis than are the actual FERS normal cost contributions, agencies should expect to continue 

to report future imputed retirement costs for their FERS employees. 
Attachment 

FEHB Program. For FY 2013, the cost factor is $5,190 per enrolled employee. Please note that 

the cost factors shown below are based on the actuarial assumptions required by SFFAS 33, as 

calculated by the FEHB actuary.

as in previous years. 

STATEMENT FOR AUDITORS 

The FY 2013 cost factors provided in this letter are being issued before an opinion by OPM’s 

independent public accounting firm can be received for FY 2013. Nonetheless, the FY 2012 cost 

factors for “regular” CSRS and FERS coverage, as well as those for the FEHB and FEGLI 

Programs were disclosed in the footnotes accompanying OPM’s consolidated FY 2012 financial 

statements. These statements received an unqualified audit opinion. The policies, procedures and 

controls pertaining to the calculations of the FY 2013 cost factors did not change from FY 2012. 

Consequently, auditors of FY 2013 financial statements can rely upon the disclosures in OPM’s

FY 2012 financial statements and the related audit opinion.
