The new guidance adheres to the core principle 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 this principle, the new guidance lists five steps that entities should follow, including identifying the contract with a customer, identifying the performance obligations in the contract, determining the transaction price, allocating the transaction price to the performance obligations in the contract and recognizing revenue when the entity satisfies a performance obligation. The new guidance becomes effective for the Company on January 1, 2017, with retrospective application permitted. Early application is not permitted. The Company is currently assessing the impact of this new guidance. In June 2014, the FASB issued a new accounting standard update on the accounting for share-based payments when the terms of an award provide that a performance target could be achieved after the requisite service period. The amendments require that a performance target that affects vesting and that could be achieved after the requisite service period is treated as a performance condition. Compensation cost should be recognized in the period in which it becomes probable that the performance target will be achieved and should represent the compensation cost attributable to the period(s) for which the requisite service has already been rendered. The new guidance becomes effective for the Company on January 1, 2016, with early adoption permitted. The Company does not believe the adoption of this guidance will have a material impact on its condensed consolidated financial statements. In August 2014, the FASB issued new guidance related to the disclosures around going concern. The new standard update provides guidance around management's responsibility to evaluate whether there is substantial doubt about an entity's ability to continue as a going concern and to provide related footnote disclosures.
