New Accounting Pronouncements, Policy [Policy Text Block]

Recent accounting developments: In May 2014, FASB issued ASU 2014-09, Revenue from Contracts with Customers. ASU 2014-09 implements a common revenue standard that clarifies the principles for recognizing revenue. The core principle of ASU 2014-09 is that 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. To achieve that core principle, an entity should apply the following steps: (i) identify the contract(s) with a customer, (ii) identify the performance obligations in the contract, (iii) determine the transaction price, (iv) allocate the transaction price to the performance obligations in the contract and (v) recognize revenue when (or as) the entity satisfies a performance obligation. ASU 2014-09 was originally effective for the Company on January 1, 2017, however, FASB recently issued ASU 2015-14 which defers the effective date in order to provide additional time for both public and private entities to evaluate the impact.ASU 2014-09 will now be effective for the Company on January 1, 2018 and it is not expected to have a significant impact on the Company’s consolidated financial statements.

In February 2015, FASB issued ASU 2015-02, Consolidation: Amendments to the Consolidation Analysis. ASU 2015-02 is intended to improve targeted areas of consolidation guidance for legal entities such as limited partnerships, limited liability corporations, and securitization structures (collateralized debt obligations, collateralized loan obligations, and mortgage-backed security transactions). The ASU focuses on the consolidation evaluation for reporting organizations that are required to evaluate whether they should consolidate certain legal entities. The ASU also reduces the number of consolidation models from four to two. ASU 2015-02 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2015 and adoption is not expected to have a significant impact on the Company’s consolidated financial statements.
