Organization, Consolidation and Presentation of Financial Statements [Abstract]
BASIS OF PRESENTATION	BASIS OF PRESENTATION The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America for interim financial information and with the instructions to Form 10-Q and Regulation S-X. Accordingly, they do not include all of the information and footnotes required by accounting principles generally accepted in the United States of America for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring adjustments) considered necessary for a fair presentation of the financial position of Applied Industrial Technologies, Inc. (the “Company”, or “Applied”) as of December 31, 2017, and the results of its operations for the three and six month periods ended December 31, 2017 and 2016 and its cash flows for the six month periods ended December 31, 2017 and 2016, have been included. The condensed consolidated balance sheet as of June 30, 2017 has been derived from the audited consolidated financial statements at that date. This Quarterly Report on Form 10-Q should be read in conjunction with the Company’s Annual Report on Form 10-K for the year ended June 30, 2017. Operating results for the three and six month periods ended December 31, 2017 are not necessarily indicative of the results that may be expected for the remainder of the fiscal year ending June 30, 2018. Change in Accounting Principle - Net Periodic and Post-retirement Benefit Costs In March 2017, the FASB issued its final standard on improving the presentation of net periodic pension and postretirement benefit costs. This standard, issued as ASU 2017-07, requires that an employer report the service cost component for defined benefit plans and postretirement plans in the same line item in the income statement as other compensation costs arising from services rendered by the employees during the period. The other components of net benefit cost are required to be presented in the income statement separately from the service cost component and outside a subtotal of income from operations. This update is effective for annual financial statement periods beginning after December 15, 2017, including interim periods within those annual periods. Early adoption is permitted as of the beginning of an annual period. The Company early adopted ASU 2017-07 in the first quarter of fiscal 2018. The impact of the adoption of this guidance resulted in the reclassification of the other components of net benefit cost from selling, distribution, and administrative expense to other income, net in the condensed statements of consolidated income, resulting in an increase to operating income. There is no impact to income before income taxes, net income, or net income per share. The amounts reclassified resulted in an increase in operating income of $200 and $401 for the three and six months ended December 31, 2016, respectively. Inventory The Company uses the last-in, first-out (LIFO) method of valuing U.S. inventories. An actual valuation of inventory under the LIFO method can be made only at the end of each year based on the inventory levels and costs at that time. Accordingly, interim LIFO calculations are based on management’s estimates of expected year-end inventory levels and costs and are subject to the final year-end LIFO inventory determination. Recently Issued Accounting Guidance In May 2014, the FASB issued its final standard on the recognition of revenue from contracts with customers. The standard, issued as ASU 2014-09, outlines a single comprehensive model for entities to use in the accounting for revenue arising from contracts with customers and supersedes most current revenue recognition guidance, including industry specific guidance. The core principle of this model is that "an entity recognizes revenue to depict the transfer of promised goods or services to a customer in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods and services." In August 2015, the FASB issued ASU 2015-14 to delay the effective date of ASU 2014-09 by one year. In accordance with the delay, the update is effective for financial statement periods beginning after December 15, 2017 and may be adopted either retrospectively or on a modified retrospective basis. Early adoption is permitted, but not before financial statement periods beginning after December 15, 2016. In March 2016 the FASB issued ASU 2016-08 and ASU 2016-10, and in May 2016 the FASB issued ASU 2016-12, which clarify the guidance in ASU 2014-09 but do not change the core principle of the revenue recognition model. The Company has evaluated the provisions of the new standard and is in the process of assessing its impact on financial statements, information systems, business processes, and financial statement disclosures. We are completing an analysis of revenue streams at each of the business units and are evaluating the impact the new standard may have on revenue recognition. The Company primarily sells purchased products and recognizes revenue at point of sale or delivery and this is not expected to change under the new standard. Preliminarily, the Company plans to use the modified retrospective method of adoption, and based on initial reviews, the standard is not expected to have a material impact on the Company's consolidated financial statements. We do anticipate expanded disclosures on revenue in order to comply with the new ASU. The Company will continue to evaluate the impacts of the adoption of the standard and the preliminary assessments are subject to change. In February 2016, the FASB issued its final standard on accounting for leases. This standard, issued as ASU 2016-02, requires that an entity that is a lessee recognize lease assets and lease liabilities on the balance sheet for all leases and disclose key information about leasing arrangements. The core principle of this update is that a "lessee should recognize the assets and liabilities that arise from leases." This update is effective for annual and interim financial statement periods beginning after December 15, 2018, with earlier application permitted. The Company has not yet determined the impact of this pronouncement on its financial statements and related disclosures. In June 2016, the FASB issued its final standard on measurement of credit losses on financial instruments. This standard, issued as ASU 2016-13, requires that an entity measure impairment of certain financial instruments, including trade receivables, based on expected losses rather than incurred losses. This update is effective for annual and interim financial statement periods beginning after December 15, 2019, with early adoption permitted for financial statement periods beginning after December 15, 2018. The Company has not yet determined the impact of this pronouncement on its financial statements and related disclosures. In August 2016, the FASB issued its final standard on the classification of certain cash receipts and cash payments within the statement of cash flows. This standard, issued as ASU 2016-15, makes a number of changes meant to add or clarify guidance on the classification of certain cash receipts and payments in the statement of cash flows. This update is effective for annual and interim financial statement periods beginning after December 15, 2018, with early adoption permitted. The Company has not yet determined the impact of this pronouncement on its financial statements and related disclosures. In October 2016, the FASB issued its final standard on the income tax consequences of intra-entity transfers of assets other than inventory. This standard, issued as ASU 2016-16, requires that an entity recognize the income tax consequences of an intra-entity transfer of an asset other than inventory when the transfer occurs and eliminates the exception for an intra-entity transfer of an asset other than inventory. This update is effective for annual and interim financial statement periods beginning after December 15, 2017, with early adoption permitted. The Company has not yet determined the impact of this pronouncement on its financial statements and related disclosures. In January 2017, the FASB issued its final standard on simplifying the test for goodwill impairment. This standard, issued as ASU 2017-04, eliminates step 2 from the goodwill impairment test and instead requires an entity to perform its annual or interim goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount. An impairment charge would be recognized for the amount by which the carrying amount exceeds the reporting unit's fair value, not to exceed the total amount of goodwill allocated to that reporting unit. This update is effective for annual or interim goodwill impairment tests in fiscal years beginning after December 15, 2019, with early adoption permitted. Upon adoption, the Company will apply this guidance prospectively to its annual and interim goodwill impairment tests and disclose the change in accounting principle. In May 2017, the FASB issued its final standard on scope of modification accounting. This standard, issued as 2017-09, provides guidance about which change to the terms or conditions of a share-based payment award require an entity to apply modification accounting. This update is effective for annual and interim financial statement periods beginning after December 15, 2017, with early adoption permitted. The Company has not yet determined the impact of this pronouncement on its financial statements and related disclosures.
