March was a great month for corporate pensions, with the funded status of plans improving by $62 billion, thanks to a 24-basis-point increase in the monthly discount rate, from February's 2.88% to 3.12% as of March 31. As a result, the funded status deficit for these plans dropped to $29 billion at month's end, compared to February's $91 billion. Milliman PFI plans are now less than two percentage points away from 'full funding' levels.
