I just received the following letter from Columbia University's Office of the Controller , Unclaimed Property Office.
Check Date 11/25/1996
Cambridge, MA 02138
According to our records, the above check (for $350 in 1996 dollars) in your name was never cashed. We are contacting you in an attempt to reissue these funds to you.
11 years! and no compound interest! Newman from Seinfeld would be impressed. I respect the Columbia Office's tenacity in tracking me down but it took a while!!
