All of the options in the tables above vest and become exercisable over a period of up to eight years. Each option will terminate approximately 10 years after the grant date.
The fair value of each share-based option is estimated on the grant date using a Black-Scholes valuation method that uses the assumptions listed above. The risk-free interest rate is based on the United States (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, net of cancellations, 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 volatility is 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, 2026 and 2025 was $5.2 and $4.1, respectively, and for the second quarter of 2026 and 2025 was $2.6 and $2.0, respectively. Unrecognized stock-based compensation expense related to outstanding unvested stock options as of June 30, 2026 was $25.2 and is expected to be recognized over a weighted average period of 3.83 years. Any future changes in estimated forfeitures will impact this amount.

The following tables present a reconciliation of the denominators used in the computation of basic and diluted net income per share and a summary of the options to purchase shares of common stock which were excluded from the diluted net income per share calculation because they were anti-dilutive:
