This stock is no longer listed on any stock exchange. It was merged with Federated. Its ticker symbol used to be MAY. All the historical databases I could find(Yahoo Finance, Big Charts and Silicon Investor) either do not recognize the symbol or do not have the information in their historical charts. I might be able to find it in the Daily Stock Price Record(book) or on the CRSP/wrds site from Wharton, but I have access to neither. I need it for determining the cost basis for my tax return.
