I did not receive a 1099-B nor any other documentation other than a Periodic Statement of purchases and sales, since my Employer was Australian. I looked at my pay slip to find the amount of the ordinary income on my W2 from selling the stock before the two year vesting period. I do not know what to do with the basis, if any, of the stock that was "Matched" after vesting with no cost to me.
this depends on how they were reported to you and included as w-2 income.
