ASU 2019-12 created an exception to the incremental approach for intraperiod tax allocation when there is a loss from continuing operations and income or a gain from other items (for example, discontinued operations or other comprehensive income). Under the historical guidance, in this situation, an entity would record an income tax provision from other items, such as unrealized gains on available-for-sale securities reported in other comprehensive income, with an offsetting income tax benefit in continuing operations. Under ASU 2019-12, an entity would record no income tax provision. We elected to adopt ASU 2019-12 effective January 1, 2019 on a prospective basis in accordance with the guidance. Because we reported a net loss and unrealized gains on available-for-sale securities during 2019 and accordingly recorded a tax provision pursuant to the legacy guidance, we have recast such results from previously reported amounts. As a result, we eliminated the tax benefit in continuing operations and tax provision in other comprehensive income (loss), which totaled $0.4 million and $1.5 million for three and six months ended June 30, 2019. </span></div><div style="text-indent:36pt;margin-top:10pt;"><span style="background-color:rgb(255,255,255, 0.0);color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%;">Additionally, certain items previously reported in specific financial statement captions have been reclassified to conform to the current period presentation.

Our accounts receivable balance contains billed and unbilled trade receivables from product sales, milestones (to the extent that they have been achieved and are due from the counterparty), other contingent payments and royalties, as well as reimbursable costs from collaborative research and development agreements. As of June 30, 2020, our accounts receivable includes $13.3 million under customer contracts from our collaboration partners and $33.9 million for unbilled net expense reimbursements from our collaboration partner Bristol-Myers Squibb Company (BMS). As of June 30, 2020, we also recorded a contract asset of $25.0 million, which we report in other current assets on our Condensed Consolidated Balance Sheet, from our collaboration partner BMS for the first patient, first visit for the registrational adjuvant melanoma trial (see Note 6 for additional information). As of December 31, 2019, our accounts receivable included $12.8 million from customer contracts and $24.0 million for unbilled net expense reimbursements from BMS. We generally do not require collateral from our customers. We perform a regular review of our customers’ credit risk and payment histories, including payments made after period end. Historically, we have not experienced credit losses from our accounts receivable. We have not recorded a reserve for credit losses at June 30, 2020 or December 31, 2019.</span></div><div style="text-indent:31.5pt;margin-top:10pt;"><span style="background-color:rgb(255,255,255, 0.0);color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%;">We are dependent on our suppliers and contract manufacturers to provide raw materials and drugs of appropriate quality and reliability and to meet applicable contract and regulatory requirements. In certain cases, we rely on single sources of supply of one or more critical materials. Consequently, in the event that supplies are delayed or interrupted for any reason, our ability to develop and produce our drug candidates or our ability to meet our supply obligations could be significantly impaired, which could have a material adverse effect on our business, financial condition and results of operations.</span></div>For our available-for-sale securities, we have significant concentrations of issuers in the banking and financial services, automotive and food and beverage industries. While our investment policy requires that we only invest in highly-rated securities and limit our exposure to any single issuer, the COVID-19 pandemic may materially affect the financial conditions of issuers. Additionally, pursuant to our investment policy, we may sell securities before maturity if the issuer’s credit rating has been downgraded below our minimum credit rating requirements, which may result in a loss on the sale. As a result of the COVID-19 pandemic, we have begun to see an increase in credit downgrades for certain of our securities. Accordingly, if the COVID-19 pandemic or other factors result in downgrades below our minimum credit rating requirements and if we decide to sell these securities, we may experience losses on such sales.
