Amortization of net loss	299			307			587			578

The components of net periodic benefit cost other than the service cost component are included in Interest and Other Income (Expense) in the Condensed Consolidated Statements of Operations.

For both the six months ended June 30, 2019 and 2018, we contributed $1.0 million to the qualified retirement plan. Currently, we do not anticipate making any additional contributions to this plan during 2019.

Compensation expense related to our defined contribution plans was $1.0 million for both the three months ended June 30, 2019 and 2018, and $2.0 million and $1.9 million for the six months ended June 30, 2019 and 2018, respectively.
