You say the cash is taxable but is it considered a capital gain or income? How is the capital gain calculated? My MHS shares was obtained from the original MRK spin off. Double problem is I have no idea what my cost of the MRK shares was since it was obtained over many years by DRIP. And I think the cost/share of mrk determines the cost/mhs. Maybe I should just take an intelligent guess for everything and let the IRS figure it out.
