Important!
If the employer assumed costs related to the plan, it is possible, indeed probable, that as a result of the employer's bankruptcy, the such costs associated with the plan's termination may be deducted from the members' accounts.
If the employer owes contributions to the pension fund, the plan administrator can make a claim to recover them.
It may turn out that unpaid contributions owing to the pension fund cannot be recovered and refunded to the plan members.
