Cost-method Investments, Description [Text Block]

Non-Marketable Securities and Other-Than-Temporary Impairment

During the year ended December 31, 2018, the Company made a $1.8 million investment in Combinati, a private company. On October 1, 2019 the Company made an additional $7.0 million investment in Combinati, bringing the Company's ownership to approximately 28.4% of the voting interest of Combinati. Effective October 1, 2019, the Company accounted for its investment in Combinati under the equity method, given the Company's significant influence over the investee due to its larger ownership percentage and its participation on the Board of Directors. The Company does not have unilateral decision making power, and therefore will not consolidate the investee. In the fourth quarter of 2019, we remeasured the existing, minority interest investment based on the fair value prior to the additional investment and recorded a gain of approximately $3.2 million in Other income, net in the Consolidated Statements of Comprehensive Income. The minority interest investment in Combinati was reclassified to equity method investments to distinguish it from other minority interest investments that take the fair value alternative.

As of March 31, 2020, the carrying value of the Company’s total investment in Combinati was $10.9 million, which exceeded the Company’s share of Combinati’s net assets by $7.6 million. For the quarter ended March 31, 2020, the Company recorded $0.6 million for its allocable share of Combinati’s net loss in its Consolidated Statement of Comprehensive Income and as an adjustment to the invested balance.

The Company owned a minority interest in another private company based in the U.S. through its initial investment of $1.0 million in the third quarter of 2012. We were informed that this private company was dissolving and ceasing operations in 2019. We recorded an impairment of $160,000 and $45,000 in Other income, net in the Consolidated Statements of Comprehensive Income during the second quarter and fourth quarter of 2019, respectively. We received the final cash payment for the remainder of our investment in the first quarter of 2020.

These investments do not have readily determinable fair values. Therefore, the Company has elected the measurement alternative for its minority interests and the investments are recorded at cost, less any impairment, including changes resulting from observable price changes. The Company regularly evaluates the carrying value of its investment for impairment and whether any events or circumstances are identified that would significantly harm the fair value of the investment. The primary indicators the Company utilizes to identify these events and circumstances are the investee’s ability to remain in business, such as the investee’s liquidity and rate of cash use, and the investee’s ability to secure additional funding and the value of that additional funding. In the event a decline in fair value is less than the investment’s carrying value, the Company will record an impairment charge in Other income, net in the Consolidated Statements of Comprehensive Income. Other than the $205,000 impairment in 2019 discussed above, the Company has not recorded any impairment charges related to these non-marketable investments.

As the inputs utilized for the Company’s periodic impairment assessment are not based on observable market data, the determination of fair value of its investments is classified within Level 3 of the fair value hierarchy. See Note 5 - Fair Value Measurement to our Condensed Consolidated Financial Statements for further information on the fair value hierarchy and the three classification levels. To determine the fair value of these investments, the Company uses all available financial information related to the entities, including information based on recent or pending third-party equity investments in these entities. In certain instances, an investment’s fair value is not estimated as there are no identified events or changes in the circumstances. There have been no unrealized gains or losses related to these Level 3 minority interest investments.
