I sold 1023 shares of BTI stock in July 2017 and am needing to report the cost. Since I inherited this stock from my mother, I looked up the value at the date of her death. I found this to be a closing price of $10.78. I also discovered that there had been one 2 for 1 split during the time I owned the stock. My source indicates that " Prices have been adjusted for splits." Does this mean that my cost is simply 1022 (current shares) X $10.78 (price end of day I inherited) ?
