WCS submitted a license application in April 2016 for consolidated interim storage license for the storage of high level waste, which was docketed for formal review by the Nuclear Regulatory Commission (“NRC”) in January 2017. Consistent with our accounting policies disclosed in Note 1 to our 2016 Annual Report we capitalize direct costs related to the acquisition of operating permits. Through March 31, 2017 we had capitalized an aggregate of $3.3 million related to the acquisition of such proposed interim storage license. Due to a substantial increase in licensing review and related costs and the inability to reach an agreement in April 2017 to extend the cost-sharing arrangement WCS had in place with one of its partners, we sent a letter to the NRC on April 18, 2017 requesting that the NRC temporarily suspend all safety and environmental reviews as well as all public participation activities associated with the application until the completion of the pending sale of WCS. We do not know if or when we would request the NRC to resume licensing review activities with regard to such proposed interim storage license. As a result, we expect to recognize an impairment charge in the second quarter of 2017 related to the write-off of interim storage license application costs previously capitalized, as we now believe it is no longer probable we would receive such license.

Upon acquiring a controlling interest in our Real Estate Management and Development Segment in December 2013, we recognized an indefinite-lived customer relationship intangible asset of $5.1 million for long-term contracts related to water delivery services to the City of Henderson, Nevada and various other users through a water system owned by BMI. Aggregate revenues associated with water delivered under the City of Henderson contract have historically represented approximately 70% of the Segment’s aggregate water delivery revenues. These contracts generally span many years and feature automatic renewing provisions. The initial City of Henderson water delivery contract extended for a period of 25 years, and contained an automatic renewal provision. In January 2016, the water delivery contract with the City of Henderson was amended. As part of such amendment, required minimum volumes were reduced, pricing was lowered, the automatic renewal provision of the contract was eliminated, and the contract term now runs through June 2040. The amendment to the City of Henderson water delivery contract represents an event or change in circumstance which triggered the need to perform a quantitative impairment analysis with respect to the intangible asset in the first quarter of 2016, in accordance with the guidance in ASC 350-30-35. Accordingly, as a result of a quantitative impairment analysis performed in the first quarter of 2016 we have concluded that the $5.1 million contract related intangible asset primarily related to the City of Henderson water delivery contract has been fully impaired as a result of the amended contract (with its reduced minimum volumes and lower pricing), and we recognized an aggregate $5.1 million contract related intangible asset impairment loss in the first quarter of 2016.
