Impairment Charges The most recent annual goodwill and indefinite-lived intangible asset impairment test was performed as of the beginning of the second quarter of 2015, noting no impairment. With the exception of our NDS reporting unit, implied fair values of all reporting units exceeded their carrying values by at least 20%. During the fourth quarter of 2014, the Company completed its annual operating plan for the NDS business following the MEDICA and RSNA tradeshows, two main tradeshows for the NDS business. Expectations for sales and operating profit were lowered significantly versus prior forecasts. The lower expectations for sales and operating profit were driven by a strategic decision to discontinue certain NDS products, lack of seasonal uptick during the fourth quarter of 2014 attributable to slower than expected hospital capital expenditures, and lower than expected customer orders from the fourth quarter tradeshows. In considering the above mentioned factors, the Company determined that a triggering event occurred in the fourth quarter of 2014 and that an interim impairment review of the goodwill and intangible assets related to the NDS reporting unit was necessary. First, the Company performed a long-lived asset recoverability test in accordance with ASC 360-10-35-15, “Impairment or Disposal of Long-Lived Assets,” on the lowest level of identifiable cash flows, which was determined to be the NDS business. The recoverability test compared the carrying value of the NDS business to the undiscounted cash flows. As a result of this recoverability test, the Company determined that the assets were not recoverable. The Company then determined the fair value of the NDS business using a discounted cash flow methodology, which resulted in a $21.8 million intangible assets impairment charge in the fourth quarter of 2014. The impairment charge is reflected in the operating results of the Vision Technologies segment. Subsequent to impairing the NDS business’s long-lived assets, step one of the goodwill impairment analysis was performed. As the carrying value of the NDS reporting unit exceeded its implied fair value, the Company performed the second step of the goodwill impairment test, comparing the implied fair value of the reporting unit’s goodwill with its carrying amount to measure the impairment loss. The implied fair value of goodwill is determined in the same manner as the amount of goodwill recognized in a business combination, whereby the estimated fair value of the reporting unit is allocated to all of the assets and liabilities of that reporting unit as if the reporting unit had been acquired in a business combination and the fair value of the reporting unit was the purchase price paid. If the carrying amount of the reporting unit’s goodwill exceeds its implied fair value, an impairment loss is recognized in an amount equal to that excess. After completing the second step of the goodwill impairment test, the Company recorded a $19.6 million goodwill impairment charge in the fourth quarter of 2014. The impairment charge is reflected in the operating results of the Vision Technologies segment. The results of the impairment review as of December 31, 2014 are summarized in the following table (in thousands):
|  | Pre-Impairment Net Carrying Value |  |  | Impairment Charge |  |  | Post-Impairment Net Carrying Value |
Goodwill |  | $ | 110,321 |  |  | $ | (19,575 | ) |  | $ | 90,746 |
Intangible assets |  |  | 89,109 |  |  |  | (21,867 | ) |  |  | 67,242 |
Total |  | $ | 199,430 |  |  | $ | (41,442 | ) |  | $ | 157,988 |
The Company did not have any goodwill or indefinite-lived intangible asset impairment charges during the year ended December 31, 2013.

If any part of goodwill has not been allocated to a reportable segment, discloses the unallocated amount and the reasons for not allocating. For each impairment loss recognized related to an intangible asset (excluding goodwill), discloses: (a) a description of the impaired intangible asset and the facts and circumstances leading to the impairment, (b) the amount of the impairment loss and the method for determining fair value, (c) the caption in the income statement or the statement of activities in which the impairment loss is aggregated, and (d) the segment in which the impaired intangible asset is reported. For each goodwill impairment loss recognized, discloses: (a) a description of the facts and circumstances leading to the impairment, (b) the amount of the impairment loss and the method of determining the fair value of the associated reporting unit, and (c) if a recognized impairment loss is an estimate not finalized and the reasons why the estimate is not final.
