the redemption of fractional shares is taxable.
let's say you had 100 shares of znga tax basis $1000
you get 4.06 shares TTWO and $350 cash
the $350 reduces your tax basis to $650 in TTWO
650/4.06 = 160.10 per share
so the .06 share had a tax basis of $9.61
for which you received $y
remaining basis in TTWO for the 4 shares 650-9.61
however, if stock was held in brokerage the 1099-B will reflect all this.
