I received a cash distribution check in April 2000 when MetLife converted from a mutual to a stock life insurance company. I also received a Form 1099-B which states that I have to report this amount on my schedule D. I have the info I need to fill out everything except the cost or other basis. What amount am I supposed to put there?? Am I supposed to figure this out on my own?? I've always done my own taxes and never had problems reporting capital gains from my mutual funds, but then again, they've always stated what the average basis was. Please help...it's the only thing I need before filing my taxes. thanks for any advise.
