On November 12, 2016, we entered into a definitive agreement to be acquired by Siemens Industry, Inc. (Siemens) and Meadowlark Subsidiary Corporation, a wholly-owned subsidiary of Siemens. The transaction is valued at $37.25 per share in cash, or approximately $4.5 billion, and has been approved by our Board of Directors. The closing of the transaction is subject to approval by the affirmative vote of the holders of at least a majority of the outstanding shares of Mentor Graphics common stock. The closing of the transaction is also subject to various customary conditions, including the expiration or termination of the applicable waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976; receipt of clearance from the Committee on Foreign Investment in the U.S. and other specified regulatory approvals; the accuracy of representations and warranties contained in the agreement. We are also subject to compliance with covenants and agreements contained in the agreement, including a restriction on the amount we can borrow of no more than $10,000 in each fiscal quarter and a prohibition on the repurchase of common stock. The closing of the transaction is not subject to a financing condition and is expected to occur in 2017.
