New Accounting Pronouncements and Changes in Accounting Principles [Text Block]	2. Recent Accounting Pronouncements and Accounting Changes In May 2014, Financial Accounting Standards Board, or FASB, issued a new standard on the recognition of revenue from contracts with customers, which includes a single set of rules and criteria for revenue recognition to be used across all industries. The revenue standard’s core principle is built on the contract between a vendor and a customer for the provision of goods and services. It attempts to depict the exchange of rights and obligations between the parties in the pattern of revenue recognition based on the consideration to which the vendor is entitled. To accomplish this objective, the standard requires five basic steps: identify the contract with the customer, identify the performance obligations in the contract, determine the transaction price, allocate the transaction price to the performance obligations in the contract, and recognize revenue when or as the entity satisfies a performance obligation. This standard is effective for annual reporting periods beginning after December 15, 2017, including interim periods during the annual period. Early adoption is prohibited for annual periods commencing before December 15, 2016. Different transition methods are available — full retrospective method, retrospective with certain practical expedients, and a modified retrospective (cumulative effect) approach. We are currently evaluating the impact of the adoption of the standard on our consolidated financial statements including selection of the transition method. In March 2016, FASB issued an amended guidance on the topic of revenue from contracts with customers relating to revenue recognition to clarify the implementation guidance on principal versus agent considerations and to address how an entity should assess whether it is the principal or the agent in contracts that include three or more parties. The effective date and transition requirements for these amendments are the same as the effective date and transition requirements of the new revenue recognition standard. We are currently evaluating the impact of these amendments on our financial statements. In April 2016, FASB issued an amended guidance to clarify the following two aspects relating revenue recognition: identifying performance obligations and the licensing implementation guidance, while retaining the related principles for those areas. Before an entity can identify its performance obligation in a contract with a customer, the entity first identifies the promised goods or services in the contract. The amendments are expected to reduce the cost and complexity of applying the guidance on identifying promised goods or services. The amendments include implementation guidance on determining whether an entity’s promise to grant a license provides a customer with either a right to use the entity’s intellectual property or a right to access the entity’s intellectual property. The amendments are intended to improve the operability and understandability of the licensing implementation guidance. The effective date and transition requirements for the amendments are the same as the effective date and transition requirements relating to the new revenue recognition standard. We are currently evaluating the impact of these amendments and the transition alternatives on our consolidated financial statements. In May 2016, FASB issued an amended guidance on the topic of revenue from contracts with customers which would affect the narrow aspects of Topic 606, including assessing the collectibility criterion and accounting for contracts that do not meet the criteria for identifying the contracts with a customer, presentation of sales taxes and other similar taxes collected from customers, noncash consideration, contract modifications at transition, completed contracts at transition, and technical correction. The effective date and transition requirements for the amendments are the same as the effective date and transition requirements relating to the new revenue recognition standard. We are currently evaluating the impact of these amendments and the transition alternatives on our consolidated financial statements. In July 2015, FASB issued an amendment to modify the inventory measurement guidance in Topic 330, Inventory , for inventory that is measured using the methods other than last-in, first-out, or LIFO, and the retail inventory method. It requires that an entity measure inventory within the scope of this update at the lower of cost and net realizable value. It eliminated the guidance in Topic 330 that required a reporting entity measuring inventory at the lower of cost or market to consider the replacement cost of inventory and the net realizable value of inventory less an approximately normal profit margin along with net realizable value in determining the market value. The guidance will be effective for annual reporting periods beginning after December 15, 2016, and interim periods during the annual period. The new standard is required to be applied prospectively with earlier application permitted as of the beginning of an interim or annual reporting period. We do not expect this change to have a significant impact on our consolidated financial statements. In January 2016, the FASB issued authoritative guidance that modifies how entities measure equity investments and present changes in the fair value of financial liabilities. Under the new guidance, entities will have to measure equity investments that do not result in consolidation and are not accounted under the equity method at fair value and recognize any changes in fair value in net income unless the investments qualify for the new practicality exception. A practicality exception will apply to those equity investments that do not have a readily determinable fair value and do not qualify for the practical expedient to estimate fair value under Accounting Standards Codification, or ASC 820, Fair Value Measurements, and as such these investments may be measured at cost. This guidance is effective for financial statements issued for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. We are currently evaluating the impact of this standard on our consolidated financial statements. In February 2016, FASB issued amended guidance for lease arrangements, which requires lessees to recognize the followings for all leases with terms longer than 12 months: a lease liability, which is a lessee’s obligation to make lease payments arising from a lease, measured on a discounted basis and a right-of-use asset, which is an asset that represents the lessee’s right to use, or control the use of, a specified asset for the lease term. The amendment is effective for financial statements issued for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years. Early adoption is permitted. We are currently evaluating the impact of this amended guidance on our consolidated financial statements. In March 2016, FASB issued amended guidance to simplify the transition to the equity method of accounting. This standard eliminates the requirement that when an existing cost method investment qualifies for use of the equity method, an investor must restate its historical financial statements, as if the equity method had been used during all previous periods. Additionally, any unrealized gain or loss in accumulated other comprehensive income (loss) will be recognized through earnings at the point an investment qualifies for the equity method. The amended guidance is effective for financial statements issued for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2016. It should be applied prospectively. Early adoption is permitted. We are currently evaluating the impact of this amended guidance on our consolidated financial statements. In March, 2016, FASB issued amended guidance which simplifies several aspects of the accounting for employee share-based payment awards, including forfeitures, employer tax withholding on share-based compensation and excess tax benefits or deficiencies. The amended guidance also clarifies the statement of cash flows presentation for share-based awards. The guidance is effective for financial statements issued for fiscal years beginning after December 15, 2016, and interim periods within those fiscal years. Early adoption is permitted in any interim or annual period for which financial statements have not yet been issued or have not been made available for issuance. We are currently evaluating the impact of this amended guidance on our consolidated financial statements. In June 2016, FASB issued amended guidance which replaces the incurred loss impairment methodology in the current guidance with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates. The amendments affect financial assets and net investment in leases that are not accounted for at fair value through net income. The new guidance is effective for financial statements issued for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. Early adoption is allowed as of the fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. We are currently evaluating the impact of this amended guidance on our consolidated financial statements.
