Recent Accounting Pronouncements [Abstract]
New Accounting Pronouncements, Policy [Policy Text Block]	Recent Accounting Pronouncements In November 2015, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2015-17, Balance Sheet Classification of Deferred Taxes, which amends Accounting Standards Codification (ASC) Topic 740, Income Taxes. The new standard eliminates the current requirement for organizations to present deferred tax liabilities and assets as current and noncurrent in a classified balance sheet. Instead, organizations will be required to classify all deferred tax assets and liabilities as noncurrent. The standard is effective for interim and annual periods beginning after December 31, 2016 and may be applied prospectively to all deferred tax liabilities and assets or retrospectively to all periods presented. Early adoption is permitted. The adoption of this guidance during the fourth quarter of 2015 resulted in a reclassification of current deferred tax assets on the Company's December 31, 2015 balance sheet and did not have a material impact on our consolidated financial position, results of operations or cash flows. Prior periods were not retrospectively adjusted for this change in accounting principle. In August 2015, the FASB issued ASU 2015-15, Presentation and Subsequent Measurement of Debt Issuance Costs Associated with Line-of-Credit Arrangements, which amends ASC Subtopic 835-30, Interest - Imputation of Interest. Given the absence of authoritative guidance within ASU 2015-03 for debt issuance costs related to line-of-credit arrangements, the SEC staff stated that they would not object to an entity deferring and presenting debt issuance costs as an asset and subsequently amortizing the deferred debt issuance costs ratably over the term of the line-of-credit arrangement, regardless of whether there are any outstanding borrowings on the line-of-credit arrangement. The standard is effective for interim and annual periods beginning after December 31, 2015 and is required to be applied on a retrospective basis. Early adoption is permitted. The adoption of this guidance during the fourth quarter of 2015 in relation to ARI's December 2015 revolving credit facility (as described further in Note 12) did not have a material impact on our consolidated financial position, results of operations or cash flows. In July 2015, the FASB issued ASU No. 2015-11, Simplifying the Measurement of Inventory, which amends ASC Topic 330, Inventory. This ASU simplifies the accounting for inventory by requiring inventory to be measured at the lower of cost and net realizable value and eliminates options that currently exist for measuring inventory at market value. Market value was defined as replacement cost, with a ceiling of net realizable value and floor of net realizable value less a normal profit margin. Net realizable value is the estimated selling price in the ordinary course of business, less reasonably predictable costs of completion, disposal and transportation. If the net realizable value of inventory is lower than its cost, the difference shall be recognized as a loss during the period in which it occurs. The amendments are effective for fiscal years, and interim periods within those years, beginning after December 15, 2016 and should be applied on a prospective basis. The Company presents inventory at the lower of cost or market and when applicable records reserves intended to reduce the carrying value of its inventory to its net realizable value. The Company does not expect a material impact to the financial statements once implemented. In April 2015, the FASB issued ASU 2015-03, Simplifying the Presentation of Debt Issuance Costs, which amends ASC Subtopic 835-30, Interest - Imputation of Interest. The new standard requires that all costs incurred to issue debt be presented in the balance sheet as a direct deduction from the carrying value of the debt. The standard is effective for interim and annual periods beginning after December 31, 2015 and is required to be applied on a retrospective basis. Early adoption is permitted. The Company expects that the adoption of this new guidance will result in a reclassification of debt issuance costs on its consolidated balance sheets. In February 2015, the FASB issued ASU No. 2015-02, which amends ASC Topic 810, Consolidations. This ASU amends the current consolidation guidance, including introducing a separate consolidation analysis specific to limited partnerships and other similar entities. This ASU requires that limited partnerships and similar legal entities provide partners with either substantive kick-out rights or substantive participating rights over the general partner in order to be considered a voting interest entity. The specialized consolidation model and guidance for limited partnerships and similar legal entities have been eliminated. There is no longer a presumption that a general partner should consolidate a limited partnership. For limited partnerships and similar legal entities that qualify as voting interest entities, a limited partner with a controlling financial interest should consolidate a limited partnership. A controlling financial interest may be achieved through holding a limited partner interest that provides substantive kick-out rights. The standard is effective for annual periods beginning after December 15, 2015. The Company is currently evaluating the standard, but does not, at this time, anticipate a material impact to the financial statements and footnote disclosures once implemented. In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606). ASU 2014-09 supersedes the revenue recognition requirements in Revenue Recognition (Topic 605), and requires entities to recognize revenue in a way that depicts the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled to in exchange for those goods or services. The new revenue recognition standard also requires disclosures that sufficiently describe the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts. ASU 2014-09 is effective for annual reporting periods beginning after December 15, 2017, including interim periods within that reporting period and is to be applied retrospectively, or as a cumulative-effect adjustment as of the date of adoption. The Company is currently evaluating the new standard, but does not, at this time, anticipate a material impact to the financial statements once implemented.
