Composite corporate bond rate table

 

Legend:

  • Corporate Bond Weighted Average Interest Rate = CB Wtd Avg

  • Permissible Range = xx to xxx%

  • Composite Corporate Bond Rate = CCBR

Note: Under changes to section 412 and the addition of section 430 by the Pension Protection Act of 2006, certain interest rates rely on the corporate bond weighted average computed under section 412(b)(5)(B)(ii)(II) as in effect for plan years starting in 2007. The table below provides those corporate bond weighted averages.
