(1)The pension settlement charge recognized for the year ended December 31, 2022 primarily consisted of a settlement loss of $8.0 million that was recorded as a result of the annuity purchase for a certain Canadian pension plan described above, partially offset by a settlement gain of $5.3 million that was recorded as a result of the annuity purchase for a portion of our U.S. qualified pension plan described above.

The pension settlement charge recognized for the year ended December 31, 2021 was due to lump sum distributions allowed for under the U.K. pension plan being in excess of interest cost for the year ended December 31, 2021. Lower interest cost was primarily a result of lower interest rates as of December 31, 2020, which were used to establish the 2021 periodic pension cost, compared to prior years.
