Your basis in the original company will be allocated between the original company and the spinoff. Suppose you bought 100 shares of Company X at $50/share or a total of $5,000. Company X has ownership in Company Y, which it spins off. That is, it gives its shareholders (which includes you) shares in Company Y. Suppose you get 25 shares of Y. You now have 100 shares of X and 25 shares of Y. The company will tell you how to allocate the $5,000.Your broker showed a $0.00 price probably because at the time the Y shares were distributed, they did not know how to allocate the $5,000 cost. Your next monthly statement should show the new cost of X and Y shares. You will have to manually adjust the Quicken registers.Hope this helps.
