1. General

In the opinion of management, the accompanying consolidated condensed financial statements contain all adjustments (consisting of normal recurring adjustments) necessary to present fairly IntriCon Corporation's (“IntriCon” or the “Company”) consolidated financial position as of March 31, 2018 and December 31, 2017, and the consolidated results of its operations and cash flows for the three months ended March 31, 2018 and 2017. Results of operations for the interim periods are not necessarily indicative of the results of operations expected for the full year or any other interim period.

In December 2016, the Company’s board of directors approved plans to discontinue its cardiac diagnostic monitoring business. The Company sold the cardiac diagnostic monitoring business on February 17, 2017 to Datrix, LLC. For all periods presented, the Company classified this business as discontinued operations, and, accordingly, has reclassified historical financial data presented herein.

The consolidated financial statements include the accounts of the Company and its consolidated subsidiaries. All material intercompany transactions and balances have been eliminated in consolidation. The Company evaluates its voting and variable interests in entities on a qualitative and quantitative basis. The Company consolidates entities in which it concludes it has the power to direct the activities that most significantly impact an entity’s economic success and has the obligation to absorb losses or the right to receive benefits that could be significant to the entity.

In December 2017, the Company acquired the remaining 80-percent stake in Hearing Help Express, Inc. (referred to as “Hearing Help Express” or “HHE”), a direct-to-consumer mail order hearing aid provider, for $650 in cash, repayment of $1,833 in debt to HHE’s 80% holder and an earn-out. The results of HHE were consolidated into the Company’s financial statements beginning October 31, 2016. Prior to the acquisition of 100% ownership in December 2017, the Company allocated income and losses to the noncontrolling interest based on ownership percentage.

In January 2018, the Company closed on the additional 33% stake in Soundperience, bringing its total ownership to 49% and its total investment to 1,500 Euros consisting of an equity investment and license agreement.
