Effective July 1, 2016, we terminated a defined benefit plan in Northern Europe and transitioned our employees to a defined contribution plan, resulting in a curtailment and settlement gain of $6.8.

During the three and nine months ended September 30, 2016, contributions made to our pension plans were $2.2 and $4.4, respectively, and contributions made to our retiree health care plan were $0.3 and $0.8, respectively. During 2016, we expect to make total contributions of approximately $5.0 to our pension plans and to fund our retiree health care payments as incurred.
