The Company determined that assets and liabilities subject to the Remy light vehicle aftermarket business sale met the held for sale criteria during the third quarter of 2016.

During the fourth quarter of 2016, the Company sold the Remy light vehicle aftermarket business for approximately $80 million in cash.

During the first three months of 2017, the Company recorded a loss of $5.3 million related to the termination of a long term property lease for a manufacturing facility located in Europe.
