New Accounting Pronouncements	3. New Accounting Pronouncements Recently Issued Accounting Standards In February 2016, the FASB issued Accounting Standards Update (“ASU”) 2016-02, Leases, an update to ASC Topic 842, Leases. This guidance requires lessees to recognize leases as assets and liabilities on their balance sheets but recognize expenses on their income statements in a manner similar to the current accounting guidance. For lessors, the guidance also modifies the classification criteria and the accounting for sales-type and direct finance leases. This update is effective for the Company for interim and annual reporting periods beginning January 1, 2019. The Company does not expect the adoption of this guidance to have a material impact on its financial statements. Recently Adopted Accounting Standards In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (Topic 606), to clarify the principles used to recognize revenue for all entities. Under ASU 2014-09 as subsequently amended and clarified (“ASC 606”), an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. In order to do so, an entity would follow the five-step process for in-scope transactions: 1) identify the contract with a customer, 2) identify the separate performance obligations in the contract, 3) determine the transaction price, 4) allocate the transaction price to the separate performance obligations in the contract, and 5) recognize revenue when (or as) the entity satisfies a performance obligation. ASC 606 was effective for the Company for interim and annual reporting periods beginning January 1, 2018. The Company adopted ASC 606 in the nine months ended September 30, 2018 using the modified retrospective method by recognizing the cumulative effect of initially applying the new revenue standard as an adjustment to the opening balance of retained deficit. The cumulative effect related to the adoption of ASC 606 was a $0.3 million decrease to the opening balance of retained deficit at January 1, 2018. The Company had deferred revenue related to its agreement with Nihon Medi-Physic Co., LTD. (“NMP”) of approximately $0.4 million at September 30, 2018 and will continue to record the revenue on a straight-line basis over the remaining estimated performance obligation period of approximately six years. The Company currently has a limited number of contracts with customers and only one revenue stream, which relates to collaboration and licensing arrangements, and which represents all of the revenue earned in the three and nine months ended September 30, 2018. The adoption of ASC 606 did not have a material impact on the Company’s financial statements and is not expected to have a material impact on the Company’s financial statements on an ongoing basis.
