We evaluate long-lived assets for potential impairment indicators whenever events or changes in circumstances indicate that the carrying amount of our assets may not be recoverable. Due to the change in market conditions, as of March 31, 2020, we evaluated whether an impairment indicator existed. Based on our current forecast and expectations of market conditions, we determined that there was no triggering event that required us to update our impairment evaluation of property, plant and equipment. However, if market conditions deteriorate further or continue to persist for an extended period of time, we may be required to assess the recoverability of our long-lived assets which could result in an impairment.
