Subsequent Event
15. Subsequent Event	On January 1, 2018, the Company adopted ASU 2016-1 “Financial Instruments,” which amended the guidance in U.S. GAAP on the classification and measurement of financial instruments. Changes to the prior guidance primarily affected the accounting for equity investments, financial liabilities under the fair value option, and the presentation and disclosure requirements for financial instruments. In addition, the ASU clarified guidance related to the valuation allowance assessment when recognizing deferred tax assets resulting from unrealized losses on available-for-sale debt securities. Upon its adoption, the Company applied the amendments by means of a cumulative-effect adjustment to the balance sheet at the beginning of the first reporting period in which the guidance was effective. On January 1, 2018, the Company adopted the new guidance and, consequently, the Company recognized approximately $4,300 of net unrealized gain in its retained earnings balance. During January and February 2018, the Company sold 1,317,503 shares of Iteris, which cost $2,398, for approximately $8,334 of proceeds and will report a loss on the sales of approximately $708.
