In March 2019, certain events, facts and circumstances occurred which indicated that certain long-lived assets in the DJ Basin and Barnett Shale reporting segments could be impaired. Consequently, we performed a recoverability assessment of certain assets within these reporting segments.

In the DJ Basin, we determined that certain processing plant assets related to our existing 20 MMcf/d plant would no longer be utilized due to our expansion plans for the Niobrara G&P system. Based on the results of the recoverability assessment and the conclusion that the carrying value was not fully recoverable, we recorded an impairment charge of $34.7 million related to these assets.

In the Barnett Shale, we determined certain compressor station assets would be shut down and decommissioned beginning in the second quarter of 2019. As a result, we recorded an impairment charge of $9.7 million related to these assets. See Note 6 for additional details.
