I went through our files and the earliest statement I could find was in 1993. It did not break the amounts into pre-1987 and post-1986 so all I have is the balance in 1993 or years thereafter and the employer contributions. I did find my termination date which was 05/31/86 so all the employer contributions were made prior to that. I used the employer contribution to do the estimate I mentioned above.
Thanks for everything.
