The Pension Protection Act of 2006 and Diversification of Employer Stock in Defined Contribution Plans

However, stand-alone ESOPs, i.e., those that do not allow employee elective deferrals or after-tax contributions, were exempt from this provision. Using detailed Form 5500 financial data for stand-alone ESOPs and those that allow employee elective deferrals or after-tax contributions, so-called KSOPs, from 2003-5 (before) and 2007-9 (after) the PPA and a quasi-experimental empirical framework, two primary empirical findings emerge.First, the share of plan assets in company stock fell 7 percentage points for KSOPs, because of the diversification provisions in PPA2006, a substantial decline. There was no change in holdings for stand-alone ESOPs. Second, most of the decline occurred in plans that had between 25-50 percent of plan assets in employer stock. Nonetheless, in 2009 still two-thirds of KSOPs had more than 10 percent of assets in company stock, the statutory limit for defined benefit pension plans.
