Stockholders' Equity

Stock Repurchases

From time to time, the Company’s Board of Directors has authorized programs under which the Company may repurchase shares of its common stock, depending on market conditions, in the open market or through privately negotiated transactions. Under the authorizations, the timing and actual number of shares subject to repurchase are at the discretion of management and are contingent on a number of factors, such as levels of cash generation from operations, cash requirements for acquisitions and the price of the Company’s common stock. As of July 1, 2018, 2.0 million shares remained authorized for repurchase under the repurchase program. The Company did not repurchase any shares of common stock under the authorizations during the six months ended July 1, 2018. The Company repurchased, reported based on trade date, 1.1 million shares of common stock at a cost of $56.6 million under the repurchase authorization during the six months ended July 2, 2017.

The Company repurchased, as reported based on trade date, approximately 123,000 shares of common stock at a cost of $7.2 million to administratively facilitate the withholding and subsequent remittance of personal income and payroll taxes for individuals receiving RSUs during the six months ended July 1, 2018. Similarly, during the six months ended July 2, 2017, the Company repurchased, as reported based on trade date, approximately 119,000 shares of common stock at a cost of $5.6 million to facilitate tax withholding for RSUs.

These shares were retired upon repurchase. The Company’s policy related to repurchases of its common stock is to charge the excess of cost over par value to retained earnings. All repurchases were made in compliance with Rule 10b-18 under the Securities Exchange Act of 1934, as amended.
