Basic and diluted earnings per share are calculated by dividing net (loss)/income attributable to WTW by the average number of ordinary shares outstanding during each period. The computation of diluted (loss)/earnings per share reflects the potential dilution that

could occur if dilutive securities and other contracts to issue shares were exercised or converted into shares or resulted in the issuance of shares that then shared in the net income of the Company.

At September 30, 2024 and 2023, there were 0.6 million restricted performance-based stock units outstanding at each period presented, and 0.5 million restricted time-based stock units outstanding at each period presented. The Company had no time-based share options outstanding and no performance-based options outstanding at September 30, 2024 and 2023.

Basic and diluted (loss)/earnings per share are as follows:


	Three Months Ended September 30,						Nine Months Ended September 30,
	2024			2023			2024			2023
Net (loss)/income attributable to WTW	$	(1,675	)	$	136		$	(1,344	)	$	433

Basic average number of shares outstanding		102			105			103			106
Dilutive effect of potentially issuable shares		—			—			—			1
Diluted average number of shares outstanding		102			105			103			107

Basic (loss)/earnings per share	$	(16.44	)	$	1.30		$	(13.11	)	$	4.08
Dilutive effect of potentially issuable shares		—			(0.01	)		—			(0.02	)
Diluted (loss)/earnings per share	$	(16.44	)	$	1.29		$	(13.11	)	$	4.06

The dilutive effect of potentially issuable shares was not computed for the three and nine months ended September 30, 2024 as the Company reported a net loss within its condensed consolidated statements of comprehensive income. Anti-dilutive restricted stock units were immaterial for the three and nine months ended September 30, 2023. There were no anti-dilutive options for the three and nine months ended September 30, 2023.
