Share-based Payment Arrangement [Abstract]

Teledyne has long-term incentive plans pursuant to which it has granted non-qualified stock options, restricted stock and performance shares to certain employees. The Company also has non-employee Board of Director stock compensation plans, pursuant to which common stock, stock options and restricted stock units have been issued to its directors.

Stock Incentive Plan

Stock option compensation expense was $5.7 million for the second quarter of 2020 and was $5.8 million for the second quarter of 2019. Stock option compensation expense was $13.1 million for the first six months of 2020 and was $14.7 million for the first six months of 2019. Employee stock option grants are charged to expense evenly over the three year vesting period except for stock options that were granted after 2018 to Teledyne’s Executive Chairman and Teledyne’s President and Chief Executive Officer which were expensed immediately. For 2020, the Company currently expects approximately $25.2 million in stock option compensation expense based on stock options outstanding at June 28, 2020. This amount can be impacted by employee retirements and terminations or stock options granted during the remainder of the year. The Company issues shares of common stock upon the exercise of stock options.

The following assumptions were used in the valuation of stock options granted in the first six months of 2020:


			2020
Expected volatility			23.7%
Risk-free interest rate range			1.50% to 1.75%
Expected life in years			6.6
Expected dividend yield			—

Based on the assumptions used in the valuation of stock options, the grant date weighted average fair value of stock options granted in the first six months of 2020 was $106.26 per share.
