Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The accompanying unaudited condensed consolidated financial statements of the Company have been prepared by the Company’s management in accordance with United States generally accepted accounting principles ("US GAAP") for interim financial information and applicable rules and regulations of the Securities Exchange Act of 1934. Accordingly, they do not include all of the information and footnotes required by US GAAP for annual financial statements. The unaudited condensed consolidated financial statements included herein contain all adjustments (consisting of normal recurring and non-recurring adjustments) which are, in the opinion of management, necessary to present fairly the financial position as of March 31, 2017 and June 30, 2016, the results of operations for the quarters and nine months ended March 31, 2017 and 2016, the statements of comprehensive income for the quarters and nine months ended March 31, 2017 and 2016, and the statements of cash flows for the nine months ended March 31, 2017 and 2016. The results of operations for the quarters and nine months ended March 31, 2017 and 2016 are not necessarily indicative of the results to be expected for a full year. These financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the fiscal year ended June 30, 2016.
Cash and Cash Equivalents	Cash and Cash Equivalents The Company considers all highly-liquid investments with original maturities of three months or less, when purchased, to be cash equivalents. The Company maintains zero-balance disbursement accounts at various financial institutions at which the Company does not maintain significant depository relationships. Due to the terms of the agreements governing these accounts, the Company generally does not have the right to offset outstanding checks written from these accounts against cash on hand, and the respective institutions are not legally obligated to honor the checks until sufficient funds are transferred to fund the checks. As a result, checks released but not yet cleared from these accounts in the amounts of $2.9 million and $78.3 million are included in accounts payable as of March 31, 2017 and June 30, 2016, respectively.
Recent Accounting Pronouncements	Recent Accounting Pronouncements In May 2014, the Financial Accounting Standards Board ("FASB") issued a comprehensive new revenue recognition standard for contracts with customers that will supersede most current revenue recognition guidance, including industry-specific guidance. The core principle of this standard is 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 core principle, the standard provides a five-step analysis of transactions to determine when and how revenue is recognized. Other major provisions include the capitalization and amortization of certain contract costs, ensuring the time value of money is considered in the transaction price, and allowing estimates of variable consideration to be recognized before contingencies are resolved in certain circumstances. This guidance also requires enhanced disclosures regarding the nature, amount, timing and uncertainty of revenue and cash flows arising from an entity’s contracts with customers. The new standard is effective for fiscal years, and interim periods within those years, beginning after December 15, 2017. The standard permits the use of either the retrospective or cumulative effect transition method. This guidance will be applicable to the Company for the fiscal year beginning July 1, 2018. We are currently in the process of evaluating the impact of this guidance on our consolidated financial results to determine the appropriate transition method for the Company. We have engaged a third-party consultant to assist with developing a multi-phase plan to assess the impact of adoption. We have also begun our initial review and analysis of business processes and current material contracts. In February 2016, the FASB issued Accounting Standards Update ("ASU") 2016-02, Leases (Topic 842) requiring lessees to reflect most leases on their balance sheets and recognize expenses on their income statements. Under the new guidance, lessees will be required to recognize 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 asset will be measured at the lease liability amount, adjusted for lease prepayments, lease incentives received, and the lessee's initial direct costs. For leases with a lease term of 12 months or less, as long as the lease does not include options to purchase the underlying assets, lessees can elect not to recognize a lease liability and right-of-use asset. Under the new guidance, lessor accounting is largely unchanged, and the accounting for sale and leaseback transactions is simplified. The standard is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. This guidance will be applicable to the Company for the fiscal year beginning July 1, 2019. The guidance must be adopted using a modified retrospective approach for leases that exist or are entered into after the beginning of the earliest comparative period in the financial statements. The Company is currently evaluating the impact on its consolidated financial statements upon the adoption of this new guidance. In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows (Topic 230) intended to reduce diversity in practice of how certain cash receipts and cash payments are presented and classified in the statement of cash flows. The update addresses eight specific cash flow issues, with the treatment of contingent consideration payments made after a business combination being the most directly applicable to the Company. The update requires that cash payments made approximately three months or less after an acquisition's consummation date should be classified as cash outflows for investing activities. Payment made thereafter up to the amount of the original contingent consideration liability should be classified as cash outflows from financing activities. Payments made in excess of the amount of the original contingent consideration liability should be classified as cash outflows from operating activities. The standard is effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. The standard will be applicable to the Company for the fiscal year beginning July 1, 2018. Early adoption is permitted, provided all eight amendments are adopted in the same period. The guidance requires adoption using a retrospective transition method. The Company is currently evaluating the impact on its consolidated financial statements upon the adoption of this new guidance. In January 2017, the FASB issued guidance clarifying the definition of a business within Accounting Standards Codification ("ASC") Topic 850 Business Combinations. The new standard narrows the definition of a business and therefore affects whether an acquisition represents the purchase of a business or an asset. The standard provides for an initial assessment to determine if substantially all of the fair value of the gross assets acquired is concentrated in a single identifiable asset or group of similar identifiable assets, qualifying as an asset, not a business. If the definition of the acquisition is not clear after the initial assessment, the guidance provides framework to determine if the asset(s) acquired include an input and a substantive process that together significantly contribute to the ability to create an output, which constitutes a business. The distinction between a business and an asset is important because asset acquisitions do not result in goodwill, do not require the expensing of transaction costs and do not record contingent consideration at fair value at the acquisition date, as well as other accounting concepts. The standard is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Early adoption is permitted as long as the transaction has not been reported in financial statements that have been issued or made available for issuance. The Company adopted the new standard in connection with an asset acquisition completed during the quarter ended March 31, 2017 (See Note 4-Acquisitions). In January 2017, the FASB issued guidance to simplify the accounting for goodwill impairment. It removes Step 2 of the goodwill impairment test, which requires a hypothetical purchase price allocation. Goodwill impairment will now be calculated as the amount by which a reporting unit’s carrying value exceeds its fair value, not exceeding the carrying amount of goodwill. In addition, income tax effects from any tax deductible goodwill shall also be considered in measuring goodwill impairment loss, if applicable. The guidance is effective for annual and interim periods beginning after December 15, 2019 and should be adopted prospectively. Early adoption is permitted for interim or annual goodwill impairment test performed with a measurement date after January 1, 2017. The Company intends to adopt the guidance prospectively during the fiscal quarter ended June 30, 2017 as our annual goodwill impairment testing measurement date is April 30, 2017 for the current fiscal year. The adoption is not expected to have an impact on the Company's consolidated financial statements.

Disclosure of accounting policy for cash and cash equivalents, including the policy for determining which items are treated as cash equivalents. Other information that may be disclosed includes (1) the nature of any restrictions on the entity's use of its cash and cash equivalents, (2) whether the entity's cash and cash equivalents are insured or expose the entity to credit risk, (3) the classification of any negative balance accounts (overdrafts), and (4) the carrying basis of cash equivalents (for example, at cost) and whether the carrying amount of cash equivalents approximates fair value.
