Tax report for stock merger
My original stock went through a few mergers, and I wonder how to do the tax report for 2009:
1) April 2000: Bought 100 shares of OnDisplay stock for 66.9/share
2) July 2000: It got bought by Vignette and became 158 vignette shares at 33.88/share
3) June 2005: Vignette did reverse split: 158 shares turned to 15 shares
4) July 2009: Vignette got merged with Open Text and 15 shares of Vignette turned to 2 shares of Open Text
I received the 1099-B form for the sale of 15 shares of Vignette stocks for year 2009. How should I report this? Should I get the cost basic from the top of the food chain (with the original OnDisplay stock), or I have to get the cost basic of the 15 shares of Vignette stock? I haven't done this reporting in the past and my investment on this went from $6700 to $200 in ten years.
Thanks,
Bao
