New Accounting Pronouncements, Policy [Policy Text Block]

Recent Accounting Pronouncement

In May 2014, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update No. 2014-09, Revenue from Contracts with Customers, which outlines a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers. The standard’s core principle is that an entity will recognize revenue when it transfers 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. Under the new standard, entities will apply the following five-step model when evaluating revenue contracts with customers:

● Identify the contract with a customer

● Identify the performance obligations in the contract

● Determine the transaction price

● Allocate the transaction price to the performance obligations in the contract

● Recognize revenue when the entity satisfies a performance obligation

The standard will be effective for annual reporting periods beginning after December 15, 2017. Entities have the option of using either a full retrospective or a modified retrospective application in the adoption of this standard. The Company is evaluating the transition method and the impact of the adoption on its consolidated financial position, results of operations and cash flows.
