I received a certificate for 100 shares of stock that I bought in 1995. A few years later, I signed up for the company's dividend reinvestment plan. After several years I had purchased a dozen more lots of stock through dividend reinvestments. When I closed the DRP account, the company issued a certificate for the whole shares in the plan and a check in lieu of the fractional share. Using the FIFO cost basis method, is the cost basis for the fractional share deducted from the original lot of 100 shares, or from the first lot(s) purchased under the DRP?
