SHAREHOLDERS’ EQUITY AND EMPLOYEE BENEFIT PLANS | SHAREHOLDERS’ EQUITY AND EMPLOYEE BENEFIT PLANS Common Stock and 401(k) Retirement Income Plans The Company has a 401(k) retirement plan (the “Plan”) for eligible U.S. employees. The Plan allows for employee contributions and matching Company contributions from 4% to 6% based upon terms and conditions of the 401(k) Plan. The following table reflects the Company’s contributions to the Plans during fiscal 2017 and 2016:
|  | Fiscal

Share Repurchase Program On August 15, 2017, the Company announced that it fully executed its $100 million share repurchase program (the "Program"), originally announced on August 27, 2014. In addition, the Company announced that its Board of Directors approved a new share repurchase program (the "New Program") that authorizes the repurchase of up to $100 million of the Company’s common shares, from time to time over the three year period ending August 1, 2020. The Company may purchase shares of its common stock through open market and privately negotiated transactions at prices deemed appropriate by management. The Company has entered into a written trading plan under Rule 10b5-1 of the Exchange Act to facilitate repurchases under the New Program. The New Program is effective immediately, may be suspended or discontinued at any time and will be funded using the Company's available cash, cash equivalents and short-term investments. The timing and amount of repurchase transactions under the New Program depend on market conditions as well as corporate and regulatory considerations. During the year ended September 30, 2017, the Company repurchased a total of 0.9 million shares of common stock at a cost of $18.2 million. The share repurchases were recorded in the periods they were delivered, and the payment of $18.2 million was accounted for as treasury stock in the Company’s Consolidated Balance Sheet. The Company records treasury stock purchases under the cost method using the first-in, first-out (FIFO) method. Upon reissuance of treasury stock, amounts in excess of the acquisition cost are credited to additional paid-in capital. If the Company reissues treasury stock at an amount below its acquisition cost and additional paid-in capital associated with prior treasury stock transactions is insufficient to cover the difference between acquisition cost and the reissue price, this difference is recorded against retained earnings. As of September 30, 2017, our remaining share repurchase authorization under the New Program was approximately $88.8 million. Accumulated Other Comprehensive Income The following table reflects accumulated other comprehensive (loss) / income reflected on the Consolidated Balance Sheets as of September 30, 2017 and October 1, 2016:

Equity-Based Compensation The Company has stockholder-approved equity-based employee compensation plans (the “Employee Plans”) and director compensation plans (the “Director Plans”) (collectively, the “Equity Plans”). Under these Equity Plans, market-based share awards (collectively, “market-based restricted stock”), time-based share awards (collectively, “time-based restricted stock”), performance-based share awards (collectively, “performance-based restricted stock”), stock options, or common stock have been granted at 100% of the market price of the Company's common stock on the date of grant. As of September 30, 2017, 5.1 million shares of common stock are available for grant to its employees and directors under the 2017 Equity Plan, including previously registered shares that have been carried forward for issuance under the 2009 Equity Plan.
• | Market-based restricted stock entitles the employee to receive common shares of the Company on the award vesting date if market performance objectives which measure relative total shareholder return (“TSR”) are attained. Relative TSR is calculated based upon the 90-calendar day average price of the Company's stock as compared to specific peer companies that comprise the GICS (45301020) Semiconductor Index. TSR is measured for the Company and each peer company over a performance period, which is generally three years. Vesting percentages range from 0% to 200% of awards granted. The provisions of the market-based restricted stock are reflected in the grant date fair value of the award; therefore, compensation expense is recognized regardless of whether the market condition is ultimately satisfied. Compensation expense is reversed if the award is forfeited prior to the vesting date.
• | In general, stock options and time-based restricted stock awarded to employees vest annually over a three-year period provided the employee remains employed by the Company. The Company follows the non-substantive vesting method for stock options and recognizes compensation expense immediately for awards granted to retirement-eligible employees, or over the period from the grant date to the date retirement eligibility is achieved.
• | In general, performance-based restricted stock (“PSU”) entitles the employee to receive common shares of the Company on the three-year anniversary of the grant date (if employed by the Company) if return on invested capital and revenue growth targets set by the Management Development and Compensation Committee (“MDCC”) of the Board of Directors on the date of grant are met. If return on invested capital and revenue growth targets are not met, performance-based restricted stock does not vest. Certain PSUs vest based on achievement of strategic goals over a certain time period or periods set by the MDCC. If the strategic goals are not achieved, the PSUs do not vest.
Equity-based compensation expense recognized in the Consolidated Statements of Operations for fiscal 2017, 2016, and 2015 was based upon awards ultimately expected to vest. In accordance with ASC No. 718, Stock Based Compensation, forfeitures have been estimated at the time of grant and were based upon historical experience. The Company reviews the forfeiture rates periodically and makes adjustments as necessary. The following table reflects total equity-based compensation expense, which includes restricted stock, stock options and common stock, included in the Consolidated Statements of Operations for fiscal 2017, 2016, and 2015:

Intrinsic value of stock options exercised is determined by calculating the difference between the market value of the Company's stock price at the time an option is exercised and the exercise price, multiplied by the number of shares. The intrinsic value of stock options outstanding and stock options exercisable is determined by calculating the difference between the Company's closing stock price on the last trading day of fiscal 2017 and the exercise price of in-the-money stock options, multiplied by the number of underlying shares. During fiscal 2017, the Company received $0.5 million in cash from the exercise of employee and non-employee director stock options. As of September 30, 2017, there were no unvested employee stock options. The following table reflects outstanding and exercisable employee stock options as of September 30, 2017:
