Actuarial losses (gains) were due to the remeasurements of U.S. and Canadian pension plans. These remeasurements were each due to lump sum distributions that exceeded or are expected to exceed service and interest costs resulting in settlement accounting for the plans. The actuarial losses recognized for the three- and nine-month periods ended May 1, 2022 were primarily due to lower than anticipated investment returns on plan assets, partially offset by an increase in discount rates used to determine the benefit obligation. The actuarial gains recognized for the three- and nine-month periods ended May 2, 2021 were primarily due to an increase in discount rates used to determine the benefit obligation, partially offset by lower than anticipated investment returns on plan assets.
