Stockholders' Equity | (3) Stockholders' Equity Dividends On July 12, 2022, our board of directors declared a quarterly dividend of $0.31 per share of common stock to be paid in cash on August 24, 2022 to shareholders of record at the close of business on July 27, 2022. Since 2011, we have paid quarterly cash dividends, and in 2020, we paid a special cash dividend late in the year. Our board of directors currently intends to continue paying quarterly cash dividends, provided that any future determination as to payment of dividends will depend on the financial condition and results of operations of the company and such other factors as are deemed relevant by the board of directors. The following table presents the cash dividends either paid previously or declared by our board of directors for future payment on a per share basis: 2022 2021 First quarter $ 0.31 $ 0.28 Second quarter $ 0.31 $ 0.28 Third quarter $ 0.31 $ 0.28 Fourth quarter $ 0.28 Total $ 0.93 $ 1.12 Stock Options The following tables summarize the details of options granted under our stock option plans that were outstanding as of June 30, 2022, and the assumptions used to value these grants. All such grants were effective at the close of business on the date of grant.

Generally, each option will terminate approximately ten years after the grant date. The fair value of each share-based option is estimated on the date of grant using a Black-Scholes valuation method that uses the assumptions listed above. The risk-free interest rate is based on the U.S. Treasury rate over the expected life of the option at the time of grant. The expected life is the average length of time over which we expect the employee groups will exercise their options, which is based on historical experience with similar grants. The dividend yield is estimated over the expected life of the option based on our current dividend payout, historical dividends paid, and expected future cash dividends. Expected stock volatilities are based on the movement of our stock price over the most recent historical period equivalent to the expected life of the option. Compensation expense equal to the grant date fair value is recognized for all of these awards over the vesting period. The stock-based compensation expense for the six-month periods ended June 30, 2022 and 2021 was $3.0 and $2.9, respectively, and the second quarter of 2022 and 2021 was $1.5 and $1.4, respectively. Unrecognized stock-based compensation expense related to outstanding unvested stock options as of June 30, 2022 was $17.2 and is expected to be recognized over a weighted average period of 4.39 years. Any future changes in estimated forfeitures will impact this amount.
