In 2014, the Company recognized a non-cash impairment of the Manufactured Methane facilities in the amount of $2.8 million ($1.7 million net of tax effect). The impairment resulted from the Company’s assessment that future cash flows, using historical costs and runtimes, were insufficient to recover the Manufactured Methane facilities’ net book value. The Manufactured Methane facilities were written down to fair value amount calculated from estimated discounted cash flows, as well as certain expressions of interest with regards to the purchase by outside parties of the Company’s Manufactured Methane facilities.
