In August 2015, the FASB issued ASU 2015-14 to defer the effective date of ASU 2014-09 by one year. In April 2016, the FASB issued ASU 2016-10 to clarify ASU 2014-09 on identifying performance obligations and licensing implementation guidance contained in the new revenue recognition standard. The new guidance is effective retrospectively for the Company for the year end ending March 31, 2019 and the interim reporting periods during the year ending March 31, 2019, with early application permitted only for the annual reporting period ending March 31, 2018 and the interim reporting periods during the year ending March 31, 2018. The Company is evaluating the existing revenue recognition policies to determine whether any contracts in the scope of the guidance will be affected by the new requirements.

The guidance is effective for the Company for the year ending March 31, 2017 and interim reporting periods during the year ending March 31, 2017. The guidance may be applied retrospectively or through a cumulative effect adjustment to equity as of the beginning of the year of adoption. Early application is permitted, including adoption in an interim period. The Company is evaluating the effects, if any, of the adoption of this revised guidance on the Company's financial position, results of operations or cash flows. In April 2015, the FASB issued ASU 2015-03, "Simplifying the Presentation of Debt Issuance Costs," which requires debt issuance costs relating to a recognized debt liability to be presented in the consolidated balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. The new guidance is effective retrospectively for the Company for the year end ending March 31, 2017 and interim reporting periods during the year ending March 31, 2017. Early adoption is permitted.

The new guidance is effective for the Company for the year ending March 31, 2018 and interim reporting periods during the year ending March 31, 2018. Early adoption is permitted.
