Basis of Presentation

The accompanying condensed consolidated financial statements include all the accounts of the Company and its wholly-owned subsidiaries. All inter-company accounts and transactions have been eliminated in consolidation. The accompanying condensed consolidated financial statements and related notes are unaudited and have been prepared in accordance with accounting principles generally accepted in the United States (“GAAP”) for interim financial reporting and pursuant to the rules and regulations of the Securities and Exchange Commission (the “SEC”) for quarterly reports on Form 10-Q, and do not include all of the note disclosures required by GAAP for complete financial statements. These condensed consolidated financial statements should, therefore, be read in conjunction with the consolidated financial statements and notes thereto for the year ended June 30, 2017 included in the Company’s Annual Report on Form 10-K for the year ended June 30, 2017. In the opinion of management, all adjustments considered necessary for a fair presentation of financial position, results of operations and cash flows of the Company have been included herein. The results of operations for the three months ended September 30, 2017 are not necessarily indicative of the operating results for any future interim period or the full year.

The Company’s fiscal year ends June 30 each year, and we refer to the fiscal year ending June 30, 2018 as “Fiscal 2018” and the fiscal year ended June 30, 2017 as “Fiscal 2017.”

Earnings per Share

Basic earnings per share attributable to the Company’s common shareholders is computed by dividing net earnings attributable to common shareholders by the weighted average number of common shares outstanding for the period. Diluted earnings per share attributable to common shareholders presents the dilutive effect, if any, on a per share basis of potential common shares (such as restricted stock units) as if they had been vested or converted during the periods presented.

The Company’s computation of diluted income per share for the three months ended September 30, 2017 and 2016 included an adjustment of 1.5 million and 1.4 million shares, respectively, to the weighted-average shares to account for the dilutive effect of the Part A and Part B units and related issuance of common shares upon vesting (see Note 8 – Stock-based Compensation) (calculated using the treasury method).

Significant Accounting Policies

There have been no changes to the Company’s significant accounting policies described in its Annual Report on Form 10-K for the year ended June 30, 2017.

Use of Estimates

The preparation of the Company’s condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, and disclosures of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expense during the reporting period. Significant estimates are used when establishing allowances for doubtful accounts and accruals for billing disputes, determining useful lives for depreciation and amortization and accruals for exit activities associated with real estate leases, assessing the need for impairment charges (including those related to intangible assets and goodwill), determining the fair values of assets acquired and liabilities assumed in business combinations, accounting for income taxes and related valuation allowances against deferred tax assets, determining the defined benefit costs and defined benefit obligations related to post-employment benefits and estimating certain restricted stock unit grant fair values used to compute the stock-based compensation liability and expense. Management evaluates these estimates and judgments on an ongoing basis and makes estimates based on historical experience, current conditions, and various other assumptions that are believed to be reasonable under the circumstances. The results of these estimates form the basis for making judgments about the carrying values of assets and liabilities as well as identifying and assessing the accounting treatment with respect to commitments and contingencies. Actual results may differ from these estimates under different assumptions or conditions.

Recently Issued Accounting Pronouncements

In August 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2016-15, Statement of Cash Flows (Topic 230): Classifications of Certain Cash Receipts and Cash Payments. The new standard provides guidance for eight changes with respect to how cash receipts and cash payments are classified in the statement of cash flows, with the objective of reducing diversity in practice. The standard is effective for fiscal years, and interim periods within those fiscal years, beginning after December 31, 2017, with early adoption permitted. The Company does not plan to early adopt, nor does it expect the adoption of this new standard to have a material impact on its condensed consolidated financial statements.

In February 2016, the FASB issued ASU 2016-02, Leases. The new guidance supersedes existing guidance on accounting for leases in Topic 840 and is intended to increase the transparency and comparability of accounting for lease transactions. ASU 2016-02 requires most leases to be recognized on the balance sheet. Lessees will need to recognize a right-of-use asset and a lease liability for virtually all leases. The liability will be equal to the present value of lease payments. The asset will be based on the liability, subject to adjustment, such as for initial direct costs. For income statement purposes, the FASB retained a dual model, requiring leases to be classified as either operating or finance. Lessor accounting remains similar to the current model, but updated to align with certain changes to the lessee model and the new revenue recognition standard (ASU 2014-09). The ASU will require both quantitative and qualitative disclosures regarding key information about leasing arrangements. The standard is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018. Early adoption is permitted. The standard must be adopted using a modified retrospective transition, and provides for certain practical expedients. Transition will require application of the new guidance at the beginning of the earliest comparative period presented. The Company established a project team and commenced an initial impact assessment process. To date, the Company has reviewed a sample of lessee and lessor arrangements and made preliminary assessments of the impact this standard will have on the consolidated financial statements. Although it is still assessing the impact of this standard, the Company expects the new guidance to significantly increase the reported assets and liabilities on the consolidated balance sheets. There are currently no plans to early adopt this ASU.

In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers, which requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. The ASU will replace most existing revenue recognition guidance in GAAP when it becomes effective. In July 2015, the FASB deferred the effective date to annual reporting periods and interim reporting periods within annual reporting periods beginning after December 15, 2017. Early adoption is permitted as of the original effective date or annual reporting periods and interim reporting periods within annual reporting periods beginning after December 15, 2016. The standard permits the use of either the retrospective or cumulative effect transition method.

In Fiscal 2017, the Company established a project team and commenced an initial impact assessment process based on a review of a sample of contracts with its customers. Lease revenue is not included in the scope of ASU 2014-09 and as a result the revenue to which the Company must apply the new guidance is generally limited to service revenue, certain maintenance revenue not covered by lease arrangements and other fees charged to customers. Although the Company is still assessing the impact of this standard on its consolidated financial statements, it has preliminarily determined that due to changes in the timing of recognition of certain installation services, discounts and promotional credits given to customers, there may be additional contract assets and liabilities recorded in the consolidated balance sheets upon adoption. Additionally, the requirement to defer incremental costs incurred to acquire a contract including sales commissions, and recognize such costs over the contract period or expected customer life may result in additional deferred charges recognized in the consolidated balance sheets and could have the impact of deferring operating expenses. The assessment of the impact of this standard on the Company’s consolidated financial statements also includes developing new accounting policies, internal controls and procedures and possible changes to our systems to facilitate the adoption of this accounting policy. The Company plans to adopt this new standard as of July 1, 2018 and based on its initial assessment expects to apply the modified retrospective method, which may result in a cumulative effect adjustment as of the date of adoption. The Company's initial assessment of changes to the reporting of its revenue and expenses and anticipated adoption method may change depending on the results of the Company’s ongoing and final assessment of this ASU. Until the Company is further along in its assessment, it does not anticipate being able to provide reasonably accurate estimates of the impact of ASU 2014-09.
