The aggregate funded ratio for U.S. corporate pension plans lost a bit of ground in October, according to investment consulting and services firm Wilshire Consulting.

While asset values increased, they were outpaced by liability increases, resulting in the funded ratio falling to 85.0 percent.

“We estimate that overall, the asset value increased by 1.4 percent due to positive returns for most asset classes, while the liability value increased by 1.7 percent during the month due to falling corporate bond yields,” stated Jeff Leonard, managing director, Wilshire Associates, and head of the Actuarial Services Group of Wilshire Consulting, in a statement.
