Q:

If I sell my shares in Crane Co., how can I determine my original cost basis?

A:

Crane Co. has no knowledge of what you originally paid for your shares and thus cannot advise you on your cost basis for tax purposes. If your original trade confirmations indicating the price you paid for Crane Co. common stock have been lost or destroyed, you should contact your broker.
