How is stock allocated in an ESOP?
Most companies allocate stock based on compensation (typically defined as the amount on the employee's W-2 tax form), plus elective deferrals under Section 401(k) plans and cafeteria plans. That is, each participant in the plan gets a percentage of the total shares allocated equal to that participant's percentage of total eligible pay. Eligible pay excludes pay in excess of $360,000 per year in 2026 (to be indexed for inflation in $5,000 increments after that). While W-2 compensation is the norm, compensation could also be defined to exclude bonuses or other "add-ons" to pay, provided the effect is not to push allocations more towards more highly paid people. About two-thirds of all ESOPs allocate on relative pay.
