The Condensed Consolidated Balance Sheet as of May 31, 2016 has been derived from audited financial statements. To prepare the financial statements in conformity with U.S. generally accepted accounting principles (“GAAP”), management has made a number of estimates and assumptions relating to the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities.

New Accounting Pronouncements In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers, which provides guidance for revenue recognition. This ASU affects any entity that either enters into contracts with customers to transfer goods or services or enters into contracts for the transfer of non-financial assets. This ASU will supersede the revenue recognition requirements in ASC 605, Revenue Recognition, and most industry-specific guidance. This ASU will also supersede certain cost guidance included in Subtopic 605-35, Revenue Recognition-Construction-Type and Production-Type Contracts. In August 2015, the FASB issued ASU No. 2015-14 which deferred the effective date of the new standard by one year which will make the new standard effective for us beginning June 1, 2018. We are currently evaluating the impact of the adoption of this new standard on our consolidated financial statements. In February 2016, the FASB issued ASU 2016-02, Leases. This ASU amends the existing accounting standards for lease accounting, including requiring lessees to recognize most leases on their balance sheets, including those classified as operating leases under the current accounting guidance. In addition, this ASU will require new qualitative and quantitative disclosures about the Company’s leasing activities. This new standard will be effective for us beginning June 1, 2019 with early adoption permitted. This ASU requires a modified retrospective transition approach for all leases existing at, or entered into after, the date of initial application, with an option to use certain transition relief. We are currently evaluating the impact of the adoption of this new standard on our consolidated financial statements.
