Stock-Based Compensation

Stock-Based Compensation:

Stock-based compensation cost for stock awards and stock options is measured at grant date, based on the fair value of the award, and is recognized over the employee requisite service period. The following table presents total stock-based compensation cost included in income from continuing operations.

(Dollars in millions)
For the three months ended March 31:	2024		2023
Cost	$	56	$	46
Selling, general and administrative	171		149
Research, development and engineering	93		74
Pre-tax stock-based compensation cost	$	320	$	268
Income tax benefits	(120)		(67)
Total net stock-based compensation cost	$	200	$	201

Pre-tax stock-based compensation cost for the three months ended March 31, 2024 increased $52 million compared to the corresponding period in the prior year due to increases in restricted stock units ($28 million), performance share units ($15 million) and stock options ($8 million). The increases are driven by stock-based compensation awards granted by the company as part of its annual cycles for executives and other employees.

Total unrecognized compensation cost related to non-vested awards at March 31, 2024 was $1.9 billion and is expected to be recognized over a weighted-average period of approximately 2.6 years.
