This is for (ezalidee) I scoured the website up and back and looked at the cost basis in the home page and did not find a single item related to the cost basis for LMCA & STRZA. So I don't know where you got this info because were I looked it is not there and I also submitted queries to the companies regarding this and no information is coming back.
November 28, 2011 - Liberty Media Corporation (Liberty Media) completes the conversion of each share of its Liberty Starz common stock (LSTZA and LSTZB) into 0.88129 of a share of the corresponding series of Liberty Capital common stock (LMCA and LMCB). The tax basis of each 0.88129 of a share of Liberty Media's LMCA and LMCB stock received by holders of Liberty Media's Liberty Starz common stock in the conversion should generally be the same as the tax basis of the share of Liberty Media's LSTZA or LSTZB stock, respectively, that is surrendered in exchange therefor. The tax basis of shares of Liberty Capital common stock held prior to the conversion is not affected by the conversion.
After looking at the web site, finally today in the evening the numbers came out and your basis is wrong. look again at the web suite , you will find a new date and the percentages allocated. 87.9948 for LMCA and 12.0052 for STRZA
