(1) BUSINESS AND BASIS OF PRESENTATION

Business

Zayo Group Holdings, Inc., a Delaware corporation, was formed on November 13, 2007, and is the parent company of a number of subsidiaries engaged in bandwidth infrastructure provision and services. Zayo Group Holdings, Inc. and its subsidiaries are collectively referred to as “Zayo Group Holdings” or the “Company.” The Company’s primary operating subsidiary is Zayo Group, LLC (“ZGL”). Headquartered in Boulder, Colorado, the Company operates bandwidth infrastructure assets, including fiber networks and datacenters, in the United States and Europe to offer:

—	Physical infrastructure, including dark fiber, mobile infrastructure and colocation services.

—	Cloud and Connectivity, previously referred to as Lit services, including wavelengths, Ethernet, IP, SONET and Cloud services.

—	Other services, provided by Zayo Professional Services and Zayo France.

On October 22, 2014, the Company completed an initial public offering (“IPO”) of shares of its common stock, which were listed on the New York Stock Exchange (“NYSE”) under the ticker symbol “ZAYO”. Prior to its IPO, Zayo Group Holdings was wholly owned by Communications Infrastructure Investments, LLC ("CII"). The Company’s fiscal year ends June 30 each year. The fiscal year ended June 30, 2014 is referred to as “Fiscal 2014” and the fiscal year ending June 30, 2015 as “Fiscal 2015.”

Stock Split and Amended and Restated Certificate of Incorporation

On October 9, 2014, the Company’s Board of Directors approved a 223,000-for-one stock split of the Company’s common stock. The stock split became effective upon filing of the amended and restated certificate of incorporation on October 10, 2014. Immediately subsequent to the stock split, 223,000,000 shares of common stock were outstanding. All of the shares outstanding and per share amounts have been retroactively adjusted to reflect the stock split in the accompanying condensed consolidated financial statements.

On October 10, 2014, the Company filed its amended and restated certificate of incorporation to authorize the issuance of additional shares of common and preferred stock, establish related voting and holding rights for these shares, and address certain other matters related to corporate governance.

Initial Public Offering

On October 22, 2014, the Company completed an IPO of 24,079,002 shares of common stock at an offering price of $19 per share. Shares sold in the IPO consisted of 16,008,679 shares sold by the Company and 8,070,323 shares sold by selling stockholders (including CII investors and employees, former employees, and directors and officers of the Company). The shares sold included the exercise of an option by the underwriters to purchase an additional 3,026,371 shares from selling shareholders. The underwriters’ option to purchase additional shares was exercised on October 20, 2014. Proceeds to the Company after deducting the underwriting discount and other offering expenses totaled approximately $282.0, and net proceeds to selling stockholders, including the exercised underwriter option, totaled approximately $150.2. Proceeds to the Company from the IPO are recorded as an increase in common stock and additional paid-in-capital, net of direct offering costs (including previously capitalized amounts), during the second quarter of Fiscal 2015. The Company’s shares were listed on the New York Stock Exchange (NYSE) on October 17, 2014.

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, 2014 included in the Company’s final prospectus filed with the SEC on March 13, 2015. In the opinion of management, all adjustments considered necessary for the 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 and nine-month periods ended March 31, 2015 are not necessarily indicative of the operating results for any future interim period or the full year.

Unless otherwise noted, dollar amounts and disclosures throughout the notes to the condensed consolidated financial statements relate to the Company’s continuing operations and are presented in millions of dollars.

Earnings or Loss per Share

Basic earnings or loss per share attributable to the Company’s common shareholders is computed by dividing net earnings or loss attributable to common shareholders by the weighted average number of common shares outstanding for the period. Diluted earnings or loss 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. No such items were included in the computation of diluted loss per share for the three and nine months ended March 31, 2015 and 2014 because the Company incurred a loss from continuing operations in each of these periods and the effect of inclusion would have been anti-dilutive.

Significant Accounting Policies

There have been no changes to the Company’s significant accounting policies described in its final prospectus filed with the SEC on March 13, 2015.

Discontinued Operations

On June 13, 2014, the Company completed a spin-off of Onvoy, LLC and its subsidiaries (“OVS”) to CII. The spin-off is reported as an equity distribution at carryover basis equal to the net assets and liabilities of OVS on the spin-off date, as the transaction was between entities under common control. See Note 3—Spin-off of Business.

Use of Estimates

The preparation of the Company’s 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 and estimating the common unit and 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

On April 7, 2015, the Financial Accounting Standards Board (“FASB”) issued Accounting Standard Update (“ASU”) 2015-03, Simplifying the Presentation of Debt Issuance Costs, which requires debt issuance costs related to a recognized debt liability to be presented on the balance sheet as a direct deduction from the debt liability, similar to the presentation of debt discounts. The ASU is effective for public business entities for fiscal years beginning after December 15, 2015, and interim periods within those fiscal years. Early application is permitted. The ASU requires retrospective application to all prior periods presented in the financial statements. The Company has elected not to early adopt ASU 2015-03. If adopted during the period, debt issuance costs and long term debt as reflected on the Company’s condensed consolidated balance sheets would decrease $73.9 and $89.4 as of March 31, 2015 and June 30, 2014, respectively.

On May 28, 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. The new standard is effective for the Company on or after July 1, 2017. Early application is not permitted. The standard permits the use of either the retrospective or cumulative effect transition method. The Company is evaluating the effect that ASU 2014-09 will have on its consolidated financial statements and related disclosures. The Company has not yet selected a transition method nor has it determined the effect of the standard on its ongoing financial reporting. In April 2015, the FASB tentatively decided to defer for one year the effective date of ASU 2014-09. The FASB also tentatively decided to permit entities to early adopt the standard. The tentative decision will be exposed in an upcoming proposed ASU.
