The lump needed to be calculated to see if I was over or under the $5,000 cash-out limit. Since I was over, I couldn't receive a lump-sum. Whether or not it was their duty to tell me the exact amount of the accrued benefit, they did.
I am interested in current lump-sum values in the event that the plan is amended to allow immediate payouts. While I may not be able to calculate my present value, I can track year-to-year changes in value.
Thanks for the other info.
