Discontinued Operations and Divestitures

On March 10, 2015, the Company sold its ASES business, which provides military aircraft integration and modifications, maintenance and logistics and support, to align with the Company's long-term primary business strategies. The initial sale price was $3 million, and additional post-closing consideration of $2 million was received in December 2016. During the three months ended December 31, 2015, the Company recorded $3 million of income from discontinued operations ($2 million after-tax), primarily due to the favorable settlement of a contractual matter with a customer of the ASES business.

In April 2014, the FASB issued guidance that modifies the definition of a discontinued operation and provides new disclosure requirements for divestitures. This guidance was effective for the Company in 2016. The ASES divestiture occurred in 2015 and is being reported based upon the previous guidance for discontinued operations.
