Defined Benefit Obligation and Other Long-Term Liabilities

Defined Benefit Obligation and Other Long-Term LiabilitiesThe components of defined benefit obligation and other long-term liabilities are as follows:

As at Dec. 31			2021			2020
Defined benefit obligation (Note 31)			228			282
Long-term incentive accruals (Note 30)			4			4
Other			21			12
Total			253			298

The liability for pension and post-employment benefits and associated costs included in compensation expenses are impacted by estimates related to changes in key actuarial assumptions, including discount rates. As a result of increases in discount rates in 2021, largely driven by increases in market benchmark rates, the defined benefit obligation has decreased by $54 million to $228 million as at Dec. 31, 2021, from $282 million as at Dec. 31, 2020.
