Show All Pursuant to the recent merger, I received a cash payment and shares of Laboratory Corporation of America Holdings common stock in exchange for shares of Covance, Inc. common stock. Is this exchange taxable? The receipt of the per share merger consideration pursuant to the merger will be a taxable transaction for U.S. federal income tax purposes. Generally, for U.S. federal income tax purposes, if you are a U.S. holder, you will recognize gain or loss equal to the difference between (i) the sum of cash received and the fair market value (as of the effective time) of the LabCorp common stock ($117.00 per share) you receive and (ii) your adjusted tax basis in the Covance common stock you exchange pursuant to the merger. If you are a non-U.S holder, the merger will generally not result in tax to you under U.S. federal income tax laws unless you have certain connections to the United States and we encourage you to seek tax advice regarding such matters. Because individual circumstances may differ, we recommend that you consult your own tax advisor to determine the particular tax effects of the merger to you.
