Tax free if in a IRA/ROTH account. If in a retail account, same as anything else -- capital gains. But given it's been more than a year, long-term capital gains.
Now there may be some that want to be 'cute' with the IRS and claim it's a "settlement" or other form of non-tax item. I'd highly suggest checking with your tax accountant if you plan on going that route.
In other words, you can expect to get a regular 1099-B from your brokerage, and that recorded with the IRS.
