New Accounting Pronouncements, Policy	Recent Accounting Pronouncements In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2014-09, “Revenue from Contracts with Customers”, which amends FASB ASC Topic 606. ASU 2014-09 provides a single, comprehensive revenue recognition model for all contracts with customers. This standard contains principles for the determination of the measurement of revenue and the timing of when such revenue is recognized. Revenue recognition will reflect the transfer of goods or services to customers at an amount that is expected to be earned in exchange for those goods or services. ASU 2014-09 was scheduled to be effective for annual reporting periods beginning after December 15, 2016, and early adoption was not permitted. In August 2015, the FASB issued ASU No. 2015-14, “Revenue from Contracts with Customers: Deferral of Effective Date”, which defers the effective date of ASU 2014-09 by one year. ASU 2014-19 is now effective for annual periods after December 15, 2017 including interim periods within that reporting period. Early application is permitted only for annual periods beginning after December 15, 2016, including interim periods within that reporting period. Management is currently evaluating the impact of these pronouncements on Lexicon’s consolidated financial statements. In April 2015, the FASB issued ASU No. 2015-03, “Simplifying the Presentation of Debt Issuance Costs.” ASU 2015-03 requires that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. During the three months ended March 31, 2016, the Company adopted ASU No. 2015-03 retrospectively for all periods presented in the accompanying consolidated balance sheets. The reclassification of debt issuance costs resulted in reductions in other assets, current portion of long-term debt and long-term debt of $2.9 million, $39,000 and $2.8 million, respectively, as of December 31, 2015. In November 2015, the FASB issued ASU No. 2015-17, “Income Taxes.” ASU 2015-17 simplifies the presentation of deferred income taxes, requiring that deferred tax assets and liabilities be classified as noncurrent in a classified balance sheet. The pronouncement is effective for fiscal years, and interim periods within those years, beginning after December 31, 2016, and early adoption is permitted. Management does not expect the adoption of this pronouncement to have a material impact on Lexicon’s consolidated financial statements. In January 2016, the FASB issued ASU No. 2016-01, “Recognition and Measurement of Financial Assets and Financial Liabilities.” ASU 2016-01 requires that most equity investments be measured at fair value, with subsequent changes in fair value recognized in net income. The pronouncement also impacts financial liabilities under the fair value option and the presentation and disclosure requirements for financial instruments. This pronouncement is effective for fiscal years, and interim periods within those years, beginning after December 15, 2017, and early adoption is not permitted. Management does not expect the adoption of this pronouncement to have a material impact on Lexicon’s consolidated financial statements. In February 2016, the FASB issued ASU No. 2016-02, “Leases.” ASU 2016-02 requires companies that lease assets to recognize a right-of-use asset and a lease liability, initially measured at the present value of the lease payments, in its balance sheet. The pronouncement will also require additional disclosures about the amount, timing and uncertainty of cash flows arising from leases. This pronouncement is effective for fiscal years, and interim periods within those years, beginning after December 15, 2018, and early adoption is permitted. Management is currently evaluating the impact of this pronouncement on Lexicon’s consolidated financial statements. In March 2016, the FASB issued ASU No. 2016-09, “Stock Compensation,” which is intended to simplify several aspects of the accounting for share-based payment award transactions. This pronouncement is effective for fiscal years, and interim periods within those years, beginning after December 15, 2016, and early adoption is permitted. Management is currently evaluating the impact of this pronouncement on Lexicon’s consolidated financial statements.
