Recent Authoritative Guidance	NOTE 2—RECENT AUTHORITATIVE GUIDANCE In February 2016, the FASB issued ASU 2016-02, Leases, which is effective for fiscal years beginning as of December 15, 2018, and interim periods within those years with early adoption permitted. Under ASU 2016-02, lessees will be required to recognize for all leases at the commencement date a lease liability, which is a lessee’s obligation to make lease payments arising from a lease measured on a discounted basis, and a right-to-use asset, which is an asset that represents the lessee’s right to use or control the use of a specified asset for the lease term. The Company adopted this standard on January 1, 2019 and applied the transition guidance as of the date of adoption, under the current period adjustment method. As a result, the Company recognized right-of-use assets and lease liabilities associated with its leases on January 1, 2019, with a cumulative-effect adjustment to the opening balance of accumulated deficit, while the comparable prior periods in its consolidated financial statements will continue to be reported in accordance with Topic 840, including the disclosures of Topic 840. The standard includes a number of optional practical expedients under the transaction guidance. The Company has elected the package of practical expedients which allows it to not reassess prior conclusions about lease identification, lease classification, and initial direct costs. The Company also made accounting policy elections by class of underlying asset to not apply the recognition requirements of the standard to leases with terms of 12 months or less and to not separate non-lease components from lease components. Consequently, each separate lease component and the non-lease components associated with that lease component will be accounted for as a single lease component for lease classification, recognition, and measurement purposes. Upon adoption of the standard, the Company recognized a lease obligation liability of $44 recorded in other current liabilities, and a right-of-use asset of $44 recorded in property and equipment, net. An adjustment of $26 was made to reduce the right-of-use asset and deferred rent to reflect the impact of the retrospective approach on adopting this guidance. The lease obligation liability was $33 as of March 31, 2019. In June 2018, the FASB issued ASU 2018-07, which simplifies the accounting for nonemployee share-based payment transactions. The amendments specify that Topic 718 applies to all share-based payment transactions in which a grantor acquires goods or services to be used or consumed in a grantor’s own operations by issuing share-based payment awards. The standard will be effective in the first quarter of fiscal year 2020, although early adoption is permitted (but no sooner than the adoption of Topic 606). The Company is currently evaluating the effect the adoption of this ASU will have on its consolidated financial statements. Other recently issued accounting updates are not expected to have a material impact on the Company’s consolidated financial statements.

NOTE 2—RECENT AUTHORITATIVE GUIDANCE

In February 2016, the FASB issued ASU 2016-02, Leases, which is effective for fiscal years beginning as of December 15, 2018, and interim periods within those years with early adoption permitted. Under ASU 2016-02, lessees will be required to recognize for all leases at the commencement date a lease liability, which is a lessee’s obligation to make lease payments arising from a lease measured on a discounted basis, and a right-to-use asset, which is an asset that represents the lessee’s right to use or control the use of a specified asset for the lease term.

The Company adopted this standard on January 1, 2019 and applied the transition guidance as of the date of adoption, under the current period adjustment method. As a result, the Company recognized right-of-use assets and lease liabilities associated with its leases on January 1, 2019, with a cumulative-effect adjustment to the opening balance of accumulated deficit, while the comparable prior periods in its consolidated financial statements will continue to be reported in accordance with Topic 840, including the disclosures of Topic 840.

The Company has elected the package of practical expedients which allows it to not reassess prior conclusions about lease identification, lease classification, and initial direct costs.
