Business Combinations On June 1, 2017, we completed the acquisition of Comverge, which was financed through borrowings on our multicurrency revolving line of credit and cash on hand.

Comverge's technologies are complementary to our Electricity segment's growing software and services offerings, and will help optimize grid performance and reliability.
