Marketable Equity Investments | Note 7. Marketable Equity Investments In connection with the agreements to license the immunotherapy technologies to Aduro Biotech, Inc., (“Aduro”) in 2009, the Company received preferred shares of Aduro, a privately held company at the time the Company received such shares. Pursuant to these license agreements, the Company was eligible to receive a 1% royalty fee on any future sales resulting from the licensed technology. For the years ended December 31, 2017, 2016 and 2015, the Company had not received any royalty payments from Aduro pursuant to this agreement. The Company historically accounted for the investment under the cost method of accounting with a net carrying value of zero. In April 2015, Aduro’s common stock began trading on the Nasdaq Global Select Market, under the symbol “ADRO”. At the time of Aduro’s initial public offering (“IPO”), the Company’s preferred shares in Aduro converted to 396,700 shares of common stock, and the fair value of the Company’s investment became readily determinable and, as a result became a marketable equity security. Therefore, the Company no longer accounted for the investment in Aduro under the cost basis of accounting. The Company reflected the investment in Aduro as an available-for-sale security included in investment in marketable equity securities on the Company’s consolidated balance sheets (Note 3) and adjusted the carrying value of this investment to fair value each quarterly reporting period, with changes in fair value recorded within other comprehensive income (loss), net of tax. During the years ended December 31, 2017 and 2016, respectively, the Company sold 346,700 and 50,000 shares of Aduro common stock and recognized a gain of $3.5 million and $0.8 million in “Other income, net” on the Company’s consolidated statements of operations. As of December 31, 2017, the Company had no remaining investment in Aduro’s common stock.

- Definition The entire disclosure for investments accounted for under the cost-method. The carrying amount of such investments may be adjusted, for example, distributions in excess of cost (return of capital) or for other-than-temporary impairments. The cost method and lower-of-cost or market, an adaptation of the cost method, is generally followed for most investments in noncontrolled corporations, in some corporate joint ventures, and to a lesser extent in unconsolidated subsidiaries in which the entity does not have the ability to exercise significant influence. + References Reference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher FASB -Name Accounting Standards Codification -Topic 325 -SubTopic 20 -Section 50 -Paragraph 1 -URI http://asc.fasb.org/extlink&oid=75025870&loc=d3e40691-111596 + Details
