Developments in Accounting Pronouncements	Accounting Standard Updates Adopted In May 2014, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2014-09 Revenue Recognition, replacing guidance currently codified in Subtopic 605-10 Revenue Recognition-Overall. The new ASU establishes a new five step principles-based framework in an effort to significantly enhance comparability of revenue recognition practices across entities, industries, jurisdictions, and capital markets. In August 2015, the FASB issued ASU No. 2015-14 Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date. ASU No. 2015-14 deferred the effective date of ASU No. 2014-09 until annual and interim reporting periods beginning after December 15, 2017. We adopted ASU No. 2014-09 as of January 1, 2018 using the modified-retrospective transition approach. There was no impact of adoption of the update to our consolidated financial statements for the three and six months ended June 30, 2018. We performed an assessment of the impact of implementation of ASU No. 2014-09, and concluded it does not change the timing of revenue recognition or amounts of revenue recognized compared to how we recognize revenue under our current policies. Adoption of ASU No. 2014-09 involves additional disclosures, where applicable, on (i) contracts with customers, (ii) significant judgments and changes in judgments in determining the timing of satisfaction of performance obligations and the transaction price, and (iii) assets recognized for costs to obtain or fulfill contracts. See Note 4 for information on our sales of products. In August 2016, the FASB issued ASU No. 2016-15 Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments. The update provides guidance on classification for cash receipts and payments related to eight specific issues. The update is effective for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years, with early adoption permitted. We adopted this update as of January 1, 2018. In November 2016, the FASB issued ASU No. 2016-18 Statement of Cash Flows (Topic 230): Restricted Cash. The update requires that a statement of cash flows explain the change during the period in the total of cash, cash equivalents, and amounts generally described as restricted cash or restricted cash equivalents. The update is effective for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years, with early adoption permitted. We adopted this update as of January 1, 2018. Cash, cash equivalents, and restricted cash on the consolidated statements of cash flows includes restricted cash of $63,345 as of June 30, 2018 and December 31, 2017 and $63,274 as of June 30, 2017 and December 31, 2016, as well as amounts previously reported for cash and cash equivalents. Accounting Standards Updates to Become Effective in Future Periods In February 2016, the FASB issued ASU No. 2016-02 Leases (Topic 842). The update modifies the classification criteria and requires lessees to recognize the assets and liabilities on the balance sheet for most leases. The update is effective for fiscal years beginning after December 15, 2018, with early adoption permitted. We are currently reviewing our leases and compiling the information required to implement the new guidance. We are currently evaluating the potential impact of implementing this update on our consolidated financial statements.
