"A flat qualified compensation limit could have several consequences. These include: [1] More compensation counted towards SERP excess benefits ... [2] Lower-than-expected qualified pension plan accruals for participants whose pay is capped ... [3] [E]mployers may find that more of their employees become classified as HCEs.... [4] Plans may see marginally worse nondiscrimination testing results (including ADP results) if more employees with large deferrals or benefits become HCEs. It could make a big difference for plans that were previously close to failing the tests."
