Common Stock

Holders of common stock are entitled to such dividends as our board of directors, in its discretion, may declare out of funds available, subject to the terms of any outstanding shares of preferred stock and other restrictions. In the event of liquidation of the Company, holders of common stock are entitled to receive, pro rata, all of the assets of the Company available for distribution, after payment of any liquidation preference to the holders of outstanding shares of preferred stock. Holders of the shares of common stock have no conversion or preemptive or other subscription rights and there are no redemption or sinking fund provisions applicable to the common stock.

Stock Purchases

For the year ending December 31, 2020, we purchased 351,926 shares of our common stock at an average price of $3.45. In October 2017 our board of directors authorized the repurchase of up to $10 million of our common stock. There is approximately $5.1 million of board authorization remaining under such plans, which have no expiration date. The table below describes the purchase of our common stock for the twelve-month periods ended December 31, 2020 and 2019:

Options and Warrants

In 2006, the Company adopted and its shareholders approved the CPS 2006 Long-Term Equity Incentive Plan (the “2006 Plan”) pursuant to which our Board of Directors, or a duly-authorized committee thereof, may grant stock options, restricted stock, restricted stock units and stock appreciation rights to our employees or employees of our subsidiaries, to directors of the Company, and to individuals acting as consultants to the Company or its subsidiaries. In June 2008, May 2012, April 2013, May 2015 and again in July 2018, the shareholders of the Company approved an amendment to the 2006 Plan to increase the maximum number of shares that may be subject to awards under the 2006 Plan to 5,000,000, 7,200,000, 12,200,000, 17,200,000 and 19,200,000, respectively, in each case plus shares authorized under prior plans and not issued. Options that have been granted under the 2006 Plan and a previous plan approved in 1997 have been granted at an exercise price equal to (or greater than) the stock’s fair value at the date of the grant, with terms generally of 7-10 years and vesting generally over 4-5 years.

The per share weighted-average fair value of stock options granted during the years ended December 31, 2020, 2019 and 2018 was $1.33, $1.11 and $1.06, respectively. That fair value was estimated using a binomial option pricing model using the weighted average assumptions noted in the following table. We use historical data to estimate the expected term of each option. The volatility estimate is based on the historical and implied volatility of our stock over the period that equals the expected life of the option. Volatility assumptions ranged from 72% to 80% for 2020, 37% to 39% for 2019, and 31% to 34% for 2018. The risk-free interest rate is based on the yield on a U.S. Treasury bond with a maturity comparable to the expected life of the option. The dividend yield is estimated to be zero based on our intention not to issue dividends for the foreseeable future.

For the years ended December 31, 2020, 2019 and 2018, we recorded stock-based compensation costs in the amount of $1.9 million, $2.1 million and $3.5 million, respectively. As of December 31, 2020, the unrecognized stock-based compensation costs to be recognized over future periods was equal to $3.2 million. This amount will be recognized as expense over a weighted-average period of 2.2 years.

At December 31, 2020 and 2019, options outstanding had intrinsic values of $11.9 million and $4.8 million, respectively. At December 31, 2020 and 2019, options exercisable had intrinsic values of $8.2 million and $4.8 million, respectively. The total intrinsic value of options exercised was $1.0 million and $1.4 million for the years ended December 31, 2020 and 2019, respectively. New shares were issued for all options exercised during the year ended December 2020 and cash of $949,000 was received. At December 31, 2020, there were a total of 270,000 additional shares available for grant under the 2006 Plan.
