Accounting Policies [Abstract] |
New Accounting Standards Updates [Policy Text Block] | New Accounting Standards Updates (ASU): During 2015, through the date of this report, the FASB issued five accounting standards updates, none of which had an immediate impact on Arrow, but could in the future. ASU 2015-01 "Income Statement - Extraordinary and Unusual Items" eliminated the concept of extraordinary items. For Arrow, the standard is effective for the first quarter of 2016. ASU 2015-02 "Consolidation" changed the analysis that a reporting entity must perform to determine whether it should consolidate certain types of legal entities. For Arrow, the standard is effective for the first quarter of 2016. ASU 2015-03 "Interest - Imputation of Interest" required debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability. There were no changes to the recognition and measurement of debt issuance costs. For Arrow, the standard is effective for the first quarter of 2016. ASU 2015-04 "Compensation-Retirement Benefits" provides several practical expedients for the measurement or, in certain circumstances, the remeasurement of defined benefit plan assets and obligations. Most of the practical expedients will not apply to Arrow, however, if used, an entity must disclose the accounting policy election and the date used to measure defined benefit plan assets and obligations. For Arrow, the standard is effective for the first quarter of 2016. ASU 2015-05 "Intangibles - Goodwill and Other - Internal use Software" provides guidance to customers about whether a cloud computing arrangement includes a software license. If a cloud computing arrangement includes a software license, then the customer should account for the software license element of the arrangement consistent with the acquisition of other software licenses. For Arrow, the standard is effective for the first quarter of 2016.
