Recent Accounting Standards and Pronouncements	2. Recent Accounting Standards and Pronouncements In May 2014, the FASB issued Accounting Standards Update (“ASU”) No. 2014-09, Revenue from Contracts with Customers (“ASU 2014-09”), which supersedes nearly all existing revenue recognition guidance under GAAP. The core principle of ASU 2014-09 is to recognize revenues when promised goods or services are transferred to customers in an amount that reflects the consideration to which an entity expects to be entitled for those goods or services. ASU 2014-09 defines a five-step process to achieve this core principle and, in doing so, more judgment and estimates may be required within the revenue recognition process than are required under existing GAAP. The standard’s effective date has been deferred by the issuance of ASU No. 2015-14, and is effective for annual periods beginning after December 15, 2017, and interim periods therein. The guidance permits using either of the following transition methods: (i) a full retrospective approach reflecting the application of the standard in each prior reporting period with the option to elect certain practical expedients, or (ii) a retrospective approach with the cumulative effect of initially adopting ASU 2014-09 recognized at the date of adoption (which includes additional footnote disclosures). Early application is permitted but not before December 15, 2016, the ASU’s original effective date. The Company is still evaluating the impact of the standard and which transition method it is going to use upon adoption. In July 2015, the FASB issued ASU No. 2015-11, Inventory (Topic 330): Simplifying the Measurement of Inventory. This ASU does not apply to inventory that is measured using last-in, first-out (“LIFO”) or the retail inventory method. The amendments apply to all other inventory, which includes inventory that is measured using FIFO or average cost. This ASU eliminates from U.S. GAAP the requirement to measure inventory at the lower of cost or market. Market under the previous requirement could be replacement cost, net realizable value, or net realizable value less an approximately normal profit margin. Entities within scope of this update will now be required to measure inventory at the lower of cost or net realizable value. Net realizable value is the estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation. Subsequent measurement is unchanged for inventory using LIFO or the retail inventory method. The amendments in this update are effective for fiscal years beginning after December 15, 2016, with early adoption permitted, and should be applied prospectively. The Company adopted ASU 2015-11 as of October 1, 2017, which did not have an impact on its consolidated financial statements. In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842), on accounting for leases which requires lessees to recognize most leases on their balance sheets for the rights and obligations created by those leases. The guidance requires enhanced disclosures regarding the amount, timing, and uncertainty of cash flows arising from leases, and will be effective for interim and annual periods beginning after December 15, 2018. Early adoption is permitted. The guidance requires the use of a modified retrospective approach. We expect our consolidated balance sheets to be materially impacted upon adoption due to the recognition of right-of-use assets and lease liabilities related to currently classified operating leases. We do not expect ASU 2016-02 to have a material impact on our consolidated statements of income though we expect a shift in the classification of expenses, the materiality of which we are currently evaluating. In January 2017, the FASB issued ASU No. 2017-01, Business Combination (Topic 805): Clarifying the Definition of a Business. According to the guidance, when substantially all of the fair value of gross assets acquired is concentrated in a single asset (or a group of similar assets), the assets acquired would not represent a business. If met, this initial screen eliminates the need for further assessment. To be considered a business, an acquisition would have to include an input and a substantive process that together significantly contribute to the ability to create outputs. ASU 2017-01 provides a framework to evaluate when an input and a substantive process are present. To be a business without outputs, there will now need to be an organized workforce. The FASB noted that outputs are a key element of a business and included more stringent criteria for aggregated sets of assets and activities without outputs. Finally, the guidance narrows the definition of the term “outputs” to be consistent with how it is described in Topic 606, Revenue from Contracts with Customers. Under the final definition, an output is the result of inputs and substantive processes that provide goods and services to customers, other revenue, or investment income, such as dividends and interest. The standard is effective for fiscal years beginning after December 15, 2017, with early adoption permitted. The amendments can be applied to transactions occurring before the guidance was issued as long as the applicable financial statements have not been issued. We have early adopted ASU 2017-01 as of October 1, 2017, and will apply its amendments to future transactions. In May 2017, the FASB issued ASU No. 2017-09, Compensation—Stock Compensation (Topic 718): Scope of Modification Accounting. The amendments of this ASU provide guidance about which changes to the terms or conditions of a share-based payment award require an entity to apply modification accounting in Topic 718. An entity should account for the effects of a modification unless all of the following are met: (1) the fair value of the modified award is the same as the fair value of the original award immediately before the modification; (2) the vesting conditions of the modified award are the same as the vesting conditions of the original award immediately before the modification; and (3) the classification of the modified award as an equity instrument or a liability instrument is the same as the classification of the original award immediately before the modification. The current disclosure requirements in Topic 718 are not changed. The amendments in this ASU are effective for all entities for annual periods, and interim periods within those annual periods, beginning after December 15, 2017, with early adoption permitted. Since March 31, 2017, we do not have any stock-based compensation awards outstanding. We have early adopted ASU 2017-09 as of October 1, 2017, and will apply its provisions to future stock compensation awards and transactions.

Since March 31, 2017, we do not have any stock-based compensation awards outstanding. We have early adopted ASU 2017-09 as of October 1, 2017, and will apply its provisions to future stock compensation awards and transactions.
