Goodwill and Intangible Assets Disclosure [Text Block] | 5. Intangible Assets : In accordance with the Accounting Standards Codification (ASC), an impairment test of indefinitely lived intangible assets is performed at least annually or more frequently if changes in circumstances or the occurrence of events indicate potential impairment. Events or changes in circumstances that could trigger an impairment review include significant nonperformance relative to the expected historical or projected future operating results, significant changes in the manner of the use of the acquired assets or the strategy for the overall business or significant negative industry or economic trends. All of the Company ’s intangible assets were recorded in connection with its July 1, 2011 acquisition of CTI. The intangible assets were evaluated on the premise of highest and best use to a market participant, primarily utilizing the income approach valuation methodology. The useful life of the CTI trade name was determined to be indefinite primarily due to its history and reputation in the marketplace, the Company’s expectation that the CTI trade name will continue to be used throughout the life of CTI, and the conclusion that there are currently no other factors identified that would limit its useful life. The useful life of the CTI customer relationships was determined to be fifteen years, based primarily on the consistent and predictable revenue source associated with the existing CTI customer base, the present value of which extends through the fifteen year amortization period. The Company will continue to evaluate the useful life assigned to our amortizable customer relationships in future periods. During 201 7 and 2016, a step zero test was performed for the indefinitely lived intangible assets and no indication of impairment was present. Intangible assets, net, consisted of the following as of December 31, 201 7 and 2016:
|  | As of December 31, 201 7 |
