Development Project Charge

In the three months ended March 31, 2014, we recorded charges of $1,440 for deferred costs associated with a gas pipeline development project in Maine no longer deemed viable.

As of March 31, 2015 and December 31, 2014, we had no deferred costs associated with development projects included in other non-current assets within our consolidated balance sheets.

Gain on Settlement of Acquisition Related Contingent Consideration

In the three months ended March 31, 2014, we recovered a portion of the purchase price holdback amount we had previously paid and were relieved of any potential contingent consideration obligation associated with the acquisition of an industrial service management business. As a result, we recorded a $1,058 gain on settlement of acquisition related contingent consideration in the three months ended March 31, 2014.
