On September 26, 2013, the Company amended the Offer (the "Amended Offer") to increase the price range at which it would purchase its common stock to a range of not greater than $7.00 nor less than $6.50 per share and to decrease the dollar amount of the Offer to $25.0 million. The Amended Offer was completed on October 15, 2013, with the Company purchasing approximately 1.0 million shares of its common stock at a purchase price of $7.00 per share, for an aggregate cost of approximately $6.9 million, excluding fees and expenses related to the Amended Offer. The 1.0 million shares represented approximately 3% of the Company's issued and outstanding shares of common stock at that time. The Company financed the Amended Offer from borrowings under the Amended Term Loan under its existing Credit Facility. See Note 9 for further detail. On March 21, 2012, the Company completed a tender offer to purchase 11.0 million shares of its common stock at a purchase price of $5.00 per share, for an aggregate cost of approximately $55.0 million, excluding fees and expenses relating to the tender offer. The 11.0 million shares accepted for purchase represented approximately 27% of the Company’s issued and outstanding shares of common stock at that time. Employee Stock Purchase Plan Effective July 1, 1998, the Company adopted an Employee Stock Purchase Plan to provide substantially all employees who have completed three months of service as of the beginning of an offering period an opportunity to purchase shares of its common stock through payroll deductions. Purchases on any one grant are limited to 10% of eligible compensation. Shares of the Company’s common stock may be purchased by employees at six-month intervals at 95% of the fair market value on the last trading day of each six-month period. The aggregate fair market value, determined as of the first trading date of the offering period, of shares purchased by an employee may not exceed $25,000 annually. The Employee Stock Purchase Plan expires on July 1, 2018. A total of 4,275,000 shares of common stock are available for purchase under the plan with a limit of 400,000 shares of common stock to be issued per offering period. For plan years 2013, 2012, and 2011, 126,330 shares, 117,757 shares and 137,215 shares, respectively, were issued. Treasury Stock On July 30, 2002, the Company announced that its Board of Directors approved the repurchase of up to $5.0 million of the Company’s common stock. Since the inception of the repurchase plan, the Board of Directors approved the repurchase of an additional $80.0 million of the Company’s common stock, thereby increasing the total program size to $85.0 million as of December 27, 2013. Under the repurchase plan, the Company may buy back shares of its outstanding stock from time to time either on the open market or through privately negotiated transactions, subject to market conditions and trading restrictions, excluding the above mentioned tender offer. As of December 27, 2013 and December 28, 2012, the Company had repurchased 22.2 million and 21.2 million shares of its common stock, respectively, at an average price of $3.62 and $3.52 per share, respectively. As of December 27, 2013, the Company had $4.6 million available under the Company’s buyback program. The Company holds repurchased shares of its common stock as treasury stock and accounts for treasury stock under the cost method. Subsequent to December 27, 2013, the Company's Board of Directors approved the repurchase of an additional $5.0 million of the Company's common stock, thereby increasing the total program size to $90.0 million. Dividends On December 7, 2012, the Company’s Board of Directors adopted a dividend policy pursuant to which the Company intends to pay annual cash dividends on its common stock. In December 2013 and 2012, the Board of Directors declared and paid annual cash dividends of $0.10 per common share, or a total of $3.1 million, to holders of the Company’s common stock. These dividends were paid from U.S. domestic sources and are accounted for as an increase to retained deficit. Shareholder Rights Plan On February 13, 2004, the Company’s Board of Directors adopted a Shareholder Rights Plan. Under the Plan, a dividend of one preferred share purchase right (a “Right”) was declared for each share of common stock of the Company that was outstanding on February 26, 2004. Each Right entitles the holder to purchase from the Company one one-thousandth of a share of Series A Junior Preferred Stock at a purchase price of $32.50, subject to adjustment. The Rights will trade automatically with the common stock and will not be exercisable until a person or group has become an “acquiring person” by acquiring 15% or more of the Company’s outstanding common stock, or a person or group commences, or publicly announces a tender offer that will result in such a person or group owning 15% or more of the Company’s outstanding common stock. However, Liberty Wanger Asset Management, L.P. (now known as Columbia Wanger Asset Management, L.P.), together with its affiliates and associates will be permitted to acquire up to 20% of the common stock without making the rights exercisable. Upon announcement that any person or group has become an acquiring person, each Right will entitle all rightholders (other than the acquiring person) to purchase, for the exercise price of $32.50, a number of shares of the Company’s common stock having a market value equal to twice the exercise price. Rightholders would also be entitled to purchase common stock of the acquiring person having a value of twice the exercise price if, after a person had become an acquiring person, the Company were to enter into certain mergers or other transactions. If any person becomes an acquiring person, the Board of Directors may, at its option and subject to certain limitations, exchange one share of common stock for each Right. The Rights have certain anti-takeover effects, in that they would cause substantial dilution to a person or group that attempts to acquire a significant interest in the Company on terms not approved by the Board of Directors. In the event that the Board of Directors determines a transaction to be in the best interests of the Company and its shareholders, the Board of Directors may redeem the Rights for $0.001 per share at any time prior to a person or group becoming an acquiring person. The Rights expired on February 13, 2014.
