BUSINESS AND BASIS OF PRESENTATION

Business

Zayo Group, LLC, a Delaware limited liability company, was formed on May 4, 2007, and is the operating parent company of a number of subsidiaries engaged in providing access to bandwidth infrastructure. Zayo Group LLC and its subsidiaries are collectively referred to as “Zayo Group” or the “Company.” The Company is a wholly-owned subsidiary of Zayo Group Holdings, Inc. (“ZGH”). Headquartered in Boulder, Colorado, the Company provides communication infrastructure solutions, including fiber and bandwidth connectivity, colocation and cloud infrastructure, to businesses primarily in the United States (“U.S.”), Canada and Europe. The Company provides its products and offerings through six segments:

Fiber Solutions, including dark fiber and mobile infrastructure solutions.

Transport, including Ethernet, wavelength, wholesale IP, and SONET solutions.

Enterprise Networks, including private lines, dedicated Internet and cloud-based computing and storage products.

Colocation, including provision of colocation space and power and interconnection offerings.

Allstream, including Cloud VoIP and Data Solutions.

Other offerings, including Zayo Professional Services (“ZPS”).

On May 3, 2018, the Company announced that it completed the first phase of its investigation on the advisability and feasibility of a conversion of ~~Zayo Group Holdings Inc. (“~~ZGH”) to a real estate investment trust for U.S. federal income tax purposes (a “REIT”). The Company has begun the next phase of its evaluation and preparation for a potential conversion of ZGH to a REIT. As part of these efforts, the Company has begun a direct dialogue with the U.S. Internal Revenue Service (“IRS”) in an effort to obtain clarity and support for its position, and ZGH is seeking a private letter ruling (“PLR”) from the IRS. The ability of ZGH to qualify for taxation as a REIT will depend upon its continuing compliance following REIT conversion with various requirements, including requirements related to the nature of its assets, the sources of its income and the distributions to its stockholders.

ZGH is requesting that the PLR address whether ZGH’s revenues from dark and lit fiber satisfy applicable REIT income tests, and ZGH’s ultimate decision to convert to a REIT may depend upon a favorable ruling from the IRS on this topic. ZGH submitted a PLR request to the IRS in July 2018, but the IRS may not provide a response until ~~late~~later in 2019 or later or may not respond at all.

On November 7, 2018, ZGH announced plans to separate into two publicly traded companies- – one to focus on providing communications infrastructure and another to leverage infrastructure to provide solutions for enterprise customers- – with the core tenets of the plan being simplification of the business and a focus on a communications infrastructure business. In February 2019, ZGH isannounced ~~evaluating~~that ~~multiple~~while ~~options~~the ~~that~~tenets ~~will~~of ~~achieve~~this plan remain intact, ZGH no longer believed it is in the ~~core~~shareholders’ ~~tenets~~best ofinterests for the ~~plan~~separation ~~and~~to ~~maximize~~include ~~shareholder~~a ~~value~~public spin.

See Note 16—Subsequent Events for information on a significant merger development.

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, 2018 included in the Company’s Annual Report on Form 10-K for the year ended June 30, 2018. In the opinion of management, all adjustments considered necessary for a fair

NOTES TO THE CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)

statements and notes thereto for the year ended June 30, 2018 included in the Company’s Annual Report on Form 10-K/A for the year ended June 30, 2018. 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 and ~~six~~nine months ended ~~December~~March 31, ~~2018~~2019 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 are presented in millions of dollars.

The Company’s fiscal year ends June 30 each year, and we refer to the fiscal year ending June 30, 2020 as “Fiscal 2020”, the fiscal year ending June 30, 2019 as “Fiscal 2019” and the fiscal year ending June 30, 2018 as “Fiscal 2018”.

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. 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, determining the fair value of plan assets 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.

Significant Accounting Policies

On July 1, 2018, the Company adopted the requirements of Accounting Standards Update (“ASU”) 2014-09, Revenue from Contracts with Customers (“ASC 606”). See “Recently Adopted Accounting Pronouncements” below and Note 12 – Revenue and Contract Costs for additional disclosure on the Company’s adoption of ASC 606 and its impact on the condensed consolidated financial statements.

There have been no other changes to the Company’s significant accounting policies as described in its Annual Report on Form 10-K/A for the year ended June 30, 2018.

Recently Issued Accounting Pronouncements

In February 2018, the Financial Accounting Standards Board (“FASB”) issued ASU 2018-02, Income Statement—Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income, which allows companies to reclassify the income tax effects resulting from tax bill H.R.1, from accumulated other comprehensive income to retained earnings. The standard also requires certain new disclosures regardless of the election. The standard is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018 (Fiscal 2020 for the Company), with early adoption permitted. The Company does not expect ASU 2018-02 to have a material impact on the 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~~

NOTES TO THE CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)

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 (ASC 606). 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 (Fiscal 2020 for the Company). Early adoption is permitted. The standard will require application of the new guidance at the beginning of the earliest comparative period presented using a modified retrospective transition, and provides for certain practical expedients. 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. Additionally, the Company has commenced its implementation of a lease accounting software system. 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 ASU 2016-02.

Recently Adopted Accounting Pronouncements

In March 2017, the FASB issued ASU 2017-07, Compensation – Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost. This ASU requires an employer to report the service cost component of net periodic pension cost and net periodic postretirement cost in the same line item in the statement of operations as other compensation costs arising from services rendered by the related employees during the period. The other net cost components are required to be presented in the statement of operations separately from the service cost component and outside a subtotal of income from operations. Additionally, the line item used in the statement of operations to present the other net cost components must be disclosed in the notes to the financial statements. This ASU is effective for fiscal years beginning after December 15, 2017 (Fiscal 2019 for the Company), and interim periods within those fiscal years, and must be applied on a retrospective basis. The adoption did not result in a material impact to the condensed consolidated financial statements for either of the three and ~~six~~nine months ended ~~December~~March 31, ~~2018~~2019 or ~~2017~~2018 and retrospective application was applied.

In November 2016, the FASB issued ASU 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash. The new standard requires a statement of cash flows to explain the change during the period in the total of cash, cash equivalents, and amounts generally described as restricted cash or restricted cash equivalents. Therefore, amounts generally described as restricted cash and restricted cash equivalents should be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flows. The standard is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2017 (Fiscal 2019 for the Company). The retrospective adoption of this accounting standard did not have a material impact on its condensed consolidated financial statements.

In August 2016, the FASB issued 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 (Fiscal 2019 for the Company). The retrospective adoption of this accounting standard did not have a material impact on its condensed consolidated financial statements.

In May 2014, the FASB issued ASC 606, which replaces numerous requirements in U.S. GAAP, including industry-specific requirements, and provides companies with a single revenue recognition model for recognizing revenue from certain contracts with customers. The core principle of the new standard is that a company should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods or services. In addition, the standard requires disclosure of the nature, amount, timing, and uncertainty of revenue and cash flows arising from contracts with customers and addressed accounting for costs to acquire and fulfill contracts. The standard does not impact the manner in which the Company accounts for revenue arrangements accounted for as leases. Effective July 1, 2018, the Company adopted the requirements of ASC 606 and used the full retrospective transition method. The full retrospective transition method requires the Company to restate each prior reporting period presented. The Company has implemented internal controls and system functionality to enable the preparation of financial information in accordance with ASC 606.

NOTES TO THE CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)

The adoption of ASC 606 has an impact on the manner in which the Company recognizes revenue associated with dark fiber sales that include the transfer of title to certain network assets, which prior to ASC 606 was considered a sale of real estate or integral equipment. Under previous GAAP, the Company deferred the recognition of revenue on the sale of network infrastructure assets that were considered to be integral equipment if the Company had a substantial continuing involvement in the transferred asset. The consideration received in this type of arrangement had historically been amortized to revenue ratably over the period in which the Company had a substantial continuing involvement in the transferred asset. Under ASC 606 the asset transferred in this type of arrangement is derecognized from the balance sheet and the amount of the transaction price attributable to the asset being sold is recognized upon customer acceptance. This change had an impact of (decreasing)/increasing the revenue previously reported by the Company during the years ended June 30, 2018 and 2017 by ($1.5) million and $20.5 million, respectively. The full retrospective adoption of ASC 606 also resulted in increasing the previously reported operating costs during the year ended June 30, 2017 by $18.8 million, which represents the net book value of assets transferred to customers in these types of arrangements during Fiscal 2017.

The assets transferred in these real estate sales had historically been included in property and equipment, net on the Company’s balance sheet. Upon the adoption of ASC 606, the net book value of these assets of $19.6 million was removed from the Company’s condensed consolidated balance sheet. The Company also derecognized from its June 30, 2018 balance sheet $1.5 million and $20.5 million in related deferred revenue, current and non-current, respectively, which represented the unamortized consideration received on these arrangements.

An additional impact from the adoption of ASC 606 is the accounting for the incremental costs of acquiring new service contracts, including certain compensation expense for internal sales representatives. Under ASC 606, the Company capitalizes these incremental costs of obtaining customer contracts and amortizes the expense over the relevant contract term. In addition, the Company will assess its deferred contract cost asset for impairment on a periodic basis. Prior to the adoption of ASC 606, compensation paid to internal sales representatives for obtaining new service contracts was expensed as incurred. The impact of the retrospective adoption of ASC 606 resulted in an increase to selling, general and administrative expenses as previously reported by the Company during the years ended June 30, 2018 and 2017 by $1.1 million and $0.2 million, respectively. Additionally, the Company recorded an increase to the previously reported other current assets and other assets on the consolidated balance sheet as of June 30, 2018 of $7.1 million and $5.6 million, respectively, to reflect the deferred cost of acquiring service contracts that will be recognized in future periods over the relevant contract term.

(2) ACQUISITIONS AND DISPOSITIONS

Since inception through ~~December~~March 31, ~~2018~~2019, the Company has consummated 45 transactions accounted for as business combinations. The acquisitions were executed as part of the Company’s business strategy of expanding through acquisitions. The acquisitions of these businesses have allowed the Company to increase the scale at which it operates, which in turn affords the Company the ability to increase its operating leverage, extend its network reach, and broaden its customer base.

The accompanying condensed consolidated financial statements include the operations of the acquired entities from their respective acquisition dates.

Acquisitions Completed During Fiscal 2018

Neutral Path Communications

On April 17, 2018, the Company acquired substantially all of the assets of Neutral Path Communications and Near North Partners (collectively, “Neutral Path”) for $33.3 million, which is net of cash acquired and also included an estimate for a contingent payment based on sales performance through June 30, 2018. ~~The purchase price is subject to net working capital and certain post-closing adjustments.~~ As of ~~December~~March 31, ~~2018~~2019, $4.0 million of the purchase consideration is being held in escrow pending the expiration of the indemnification adjustment period. The all-cash acquisition was funded with cash on hand and was considered an asset purchase for U.S. federal income tax purposes. Neutral Path is a long haul infrastructure provider, providing access to a fiber network section in the Midwest. The transaction added owned plus additional leased route miles to the Company’s extensive North American network, including a unique high-count fiber route from Minneapolis to Omaha.

McLean Data Center

10On April 4, 2018, the Company acquired McLean Data Center, a privately owned data center, for an insignificant amount. The acquisition was considered an asset purchase for U.S. federal income tax purposes and a business combination for accounting purposes.

The all-cash acquisition was funded with cash on hand and debt and was considered an asset purchase for U.S. federal income tax purposes. ~~Additional connectivity of the route will be enabled by Zayo’s existing network.~~

Optic Zoo Networks

On January 18, 2018, the Company acquired Vancouver, BC Canada-based Optic Zoo Networks for net purchase consideration of CAD $30.9 million (or $24.8 million), net of cash acquired, subject to certain post-closing adjustments. Optic Zoo Networks owns and provides access to high-capacity fiber in Vancouver. As of ~~December~~March 31, ~~2018~~2019, CAD $3.1 million (or $2.3 million) of the purchase consideration is being held in escrow pending the expiration of the indemnification adjustment period. The acquisition was funded with cash on hand and was considered a stock purchase for U.S. federal income tax purposes.

Acquisition Method Accounting Estimates

The Company initially recognizes the assets and liabilities acquired from the aforementioned acquisitions based on its preliminary estimates of their acquisition date fair values. As additional information becomes known concerning the acquired assets and assumed liabilities, management may make adjustments to the opening balance sheet of the acquired company up to the end of the measurement period, which is no longer than a one year period following the acquisition date. The determination of the fair values of the acquired assets and liabilities assumed (and the related determination of estimated lives of depreciable tangible and identifiable intangible assets) requires significant judgment. As of December 31, 2018, for the Optic Zoo Networks and McLean Data Center acquisitions, the Company has completed its fair value analysis and calculations in sufficient detail necessary to arrive at the final estimates of the fair value of working capital and non-working capital acquired assets and assumed liabilities, including the allocations to goodwill and intangible assets, property and equipment and resulting deferred taxes. For the Spread Networks acquisition, the items with the highest likelihood of change are working capital related accounts and goodwill. For the Neutral Path acquisition, the Company has not completed its fair value analysis and related calculations, and the Company continues to refine its estimates of the fair value of working capital and non-working capital acquired assets and assumed liabilities and such estimates are subject to revision pending the final fair value determination. As a result of integrated reporting, it is impracticable to determine the amount of revenue and net income associated with each acquisition recognized in the post-acquisition period.

11As of March 31, 2019, the Company has completed its fair value analysis and calculations in sufficient detail necessary to arrive at the final estimates of the fair value of working capital and non-working capital acquired assets and assumed liabilities, including the allocations to goodwill and intangible assets, property and equipment and resulting deferred taxes for all of its acquisitions completed during Fiscal 2018. As a result of integrated reporting, it is impracticable to determine the amount of revenue and net income associated with each acquisition recognized in the post-acquisition period.

The goodwill arising from the Company’s acquisitions results from synergies, anticipated incremental sales to the acquired company customer base and economies-of-scale expected from the acquisitions. The Company has allocated the goodwill to the reporting units (in existence on the respective acquisition dates) that were expected to benefit from the acquired goodwill. The allocation was determined based on the excess of the estimated fair value of the reporting unit over the estimated fair value of the individual assets acquired and liabilities assumed that were assigned to the reporting units. See Note 3 – Goodwill for the allocation of the Company's acquired goodwill to each of its reporting units.

In the Company’s acquisitions, the Company acquired certain customer relationships. These relationships represent a valuable intangible asset, as the Company anticipates continued business from the acquired customer bases. The Company’s estimate of the fair value of the acquired customer relationships is generally based on a multi-period excess earnings valuation technique that utilizes Level 3 inputs.

Transaction Costs

Transaction costs include expenses associated with professional services (i.e., legal, accounting, regulatory, etc.) rendered in connection with signed and/or closed acquisitions or disposals, travel expense, severance expense incurred associated with acquisitions or disposals, and other direct expenses incurred that are associated with signed and/or closed acquisitions or disposals and unsuccessful acquisitions. The Company incurred transaction costs of $20.89 million and $34.54 million for the three and ~~six~~nine months ended ~~December~~March 31, ~~2018~~2019, respectively, and $53.93 million and $1417.25 million for the three and ~~six~~nine months ended ~~December~~March 31, ~~2017~~2018, respectively.

Scott-Rice Telephone Co.

On July 31, 2018, the Company completed the sale of Scott-Rice Telephone Co. (“SRT”), a Minnesota incumbent local exchange carrier, for $42.2 million to Nuvera Communications, Inc. (formerly New Ulm Telecom, Inc.). As of ~~December~~March 31, ~~2018~~2019, $3.2 million of purchase consideration was held in escrow. The Company recognized a pre-tax gain of $5.5 million on the sale, which is included in other income, net in the condensed consolidated statements of operations. The Company acquired SRT as part of its March 1, 2017 purchase of Electric Lightwave Parent, Inc. and it was included as part of the Allstream segment. SRT had a pre-tax net loss of $1.6 million for the year ended June 30, 2018 and pre-tax net income of $2.9 million from when it was acquired in March 1, 2017 through June 30, 2017.

SRT qualified as held-for-sale as of March 31, 2018 and was classified as held-for-sale in the Company’s June 30, 2018 balance sheet. The Company concluded that SRT was not a significant disposal group and did not represent a strategic shift, and therefore was not classified as discontinued operations.

The Company’s goodwill balance was $1,~~706~~709.64 million and $1,719.1 million as of asMarch ~~of December~~ 31, ~~2018~~2019 and June 30, 2018, respectively.

The Company’s reporting units are comprised of its strategic product groups (“SPG” or “SPGs”). Effective April 1, 2018, the Company implemented further organizational changes by creating two new reporting units: CloudLink Solutions (“CloudLink”) and Live Video Solutions (“Live Video”). In connection with the organizational change, goodwill was re-allocated to the Company’s SPGs on a relative fair value basis. The Company completed an assessment immediately prior to and after the organizational change at the SPG level and determined that it is more likely than not that the fair value of the Company’s reporting units is greater than their carrying amounts.

As of ~~December~~March 31, ~~2018~~2019, the Company’s SPGs were comprised of the following: Fiber Solutions, Zayo Wavelength Solutions (“Waves”), Zayo SONET Solutions (“SONET”), Zayo Ethernet Solutions (“Ethernet”), Live Video, Wide Area Networks (“WANs”, formerly Enterprise Private and Connectivity), Zayo Cloud Solutions (“Cloud”), Zayo Colocation (“zColo”), CloudLink, Allstream, and Other (primarily ~~Zayo Professional Services~~ZPS).

Term Loan Facility and Revolving Credit Facility

On May 6, 2015, the Company and Zayo Capital, Inc. (“Zayo Capital”) entered into an Amendment and Restatement Agreement whereby ~~its~~the Credit Agreement (the “Credit Agreement”) governing ~~its~~their senior secured term loan facility (the “Term Loan Facility”) and $450.0 million senior secured revolving credit facility (the “Revolver”) was amended and restated in its entirety. The amended and restated Credit Agreement extended the maturity date of a portion of the outstanding term loans under the Term Loan Facility from July 2, 2019 to May 6, 2021, which was subsequently revised to January 19, 2021 in Incremental Amendment No. 2 (as defined and discussed below). The terms of the Term Loan Facility require the Company to make quarterly principal payments of 25 basis points per quarter of the original loan amount (unless reduced by any prepayments) plus an annual payment of up to 50% of excess cash flow, as determined in accordance with the Credit Agreement (no such annual payment was required during Fiscal 2018).

On January 15, 2016, the Company and Zayo Capital entered into an Incremental Amendment (the “Amendment”) to ~~its~~the Credit Agreement. Under the terms of the Amendment, the portion of the Term Loan Facility due 2021 was increased by $400.0 million (the “Incremental Term Loan”). The additional amounts borrowed bear interest at LIBOR plus 3.5% with a minimum LIBOR rate of 1.0%. The $400.0 million add-on was priced at 99.0%. No other terms of the Credit Agreement were amended. The Incremental Term Loan proceeds were used to fund the acquisition of Allstream, Inc. and Allstream Fiber U.S. Inc. and for general corporate purposes.

On July 22, 2016, the Company and Zayo Capital entered into a Repricing Amendment (the “Repricing Amendment”) to the Credit Agreement. Per the terms of the Repricing Amendment, the Incremental Term Loan was repriced at par to bear interest at a rate of LIBOR plus 2.75%, with a minimum LIBOR rate of 1.0%, which represented a downward adjustment of 75 basis points. No other terms of the Credit Agreement were amended.

On January 19, 2017, the Company and Zayo Capital entered into an Incremental Amendment No. 2 (the “Incremental Amendment”) to the Company’s Credit Agreement. Per the terms of the Incremental Amendment, the existing $1.85 billion of term loans under the Credit Agreement were repriced at 99.75% with one $500.0 million tranche that bears interest at a rate of LIBOR plus 2.0%, with a minimum LIBOR rate of 0.0% and a maturity date of four years from incurrence (January 19, 2021), which represents a downward adjustment of 75 basis points along with the lowering of the previous LIBOR floor, and a second $1.35 billion tranche (the “B-2 Term Loan” and along with the $500.0 million tranche, the “Refinancing Term Loans”) that bears interest at a rate of LIBOR plus 2.5%, with a minimum LIBOR rate of 1.0% and a maturity of seven years from incurrence, which represents a downward adjustment of 25 basis

~~LIBOR rate of 1.0% and a maturity of seven years from incurrence, which represents a downward adjustment of 25 basis~~ points. In addition, per the terms of the Incremental Amendment, the Company and Zayo Capital added a new $650.0 million term loan tranche under the Credit Agreement (the “Electric Lightwave Incremental Term Loan”) that bears interest at LIBOR plus 2.5%, with a minimum LIBOR rate of 1.0%, with a maturity of seven years from the closing date of the Incremental Amendment. In connection with the Incremental Amendment, the full $2,500.0 million Term Loan Facility, including the Refinancing Term Loans and the Electric Lightwave Incremental Term Loan, was re-issued at a price of 99.75%. No other material terms of the Credit Agreement with respect to the Refinancing Term Loans and the Electric Lightwave Incremental Term Loan were amended.

No other terms of the Credit Agreement were amended.

In connection with the Repricing Amendment No. 2, the Company recognized an expense of $4.9 million during the ~~six~~nine months ended ~~December~~March 31, ~~2017~~2018 associated with debt extinguishment. The $4.9 million loss on extinguishment of debt primarily represents non-cash expenses associated with the write-off of unamortized debt issuance costs and the issuance discounts on the portion of the Credit Agreement, as further amended. The loss on extinguishment of debt also includes certain fees paid to third parties involved in the Repricing Amendment No. 2.

On December 22, 2017, ~~ZGL~~the Company and Zayo Capital entered into a third repricing amendment (the “Repricing Amendment No. 3”) to the Credit Agreement. Per the terms of the Repricing Amendment No. 3, the Revolver under the Credit Agreement was repriced to bear interest at a rate of LIBOR plus 1.00% to LIBOR plus 1.75% per annum based on the Company’s leverage ratio, which represented a downward adjustment of 100 basis points. No other terms of the Credit Agreement were amended. The Revolver matures on April 17, 2020., which was subsequently extended as further defined and discussed below in Note 16 – Subsequent Events. The Credit Agreement also allows for letter of credit commitments of up to $50.0 million. The Revolver is subject to a fee per annum of 0.25% to 0.375% (based on ~~ZGL~~the Company’s current leverage ratio) of the weighted-average unused capacity, and the undrawn amount of outstanding letters of credit backed by the Revolver are subject to a 0.25% fee per annum. Outstanding letters of credit backed by the Revolver are subject to a fee of 1.00% to 1.75% per annum based upon ~~ZGL~~the Company’s leverage ratio.

On February 26, 2018, ~~ZGL~~the Company and Zayo Capital entered into an amendment (the “Incremental Amendment No. 3”) to the Credit Agreement. Per the terms of the Incremental Amendment No. 3, the Company added a new $150 million term loan tranche under the Credit Agreement (the “Incremental $150 Million Term Loan”). The Incremental $150 Million Term Loan bears interest at LIBOR plus 2.25%, with a minimum LIBOR rate of 1.0%, with a maturity date of January 19, 2024, which is coterminous with the B-2 Term Loan. The Company used the proceeds of the Incremental $150 Million Term Loan for general corporate purposes, including the funding of acquisitions permitted under the Credit Agreement. No other terms of the Credit Agreement were amended.

The weighted average interest rates (including margin) on the Term Loan Facility were approximately 4.7% and 4.3% as of ~~December~~March 31, ~~2018~~2019 and June 30, 2018, respectively.

On December 22, 2017, the U.S. federal government enacted a tax bill, H.R.1, An Act to Provide for Reconciliation Pursuant to Titles II and V of the Concurrent Resolution on the Budget for Fiscal Year 2018, previously known as the Tax Cuts and Jobs Act of 2017 (“U.S. Tax Reform”). U.S. Tax Reform reduced the U.S. corporate tax rate from 35% to 21%, created a territorial tax system with a one-time mandatory repatriation tax on previously deferred foreign earnings, and changed business-related deductions and credits.

ASC 740, Income Taxes, requires companies to recognize the effect of tax law changes in the period of enactment. The SEC staff issued SAB 118, Income Tax Accounting Implications of the Tax Cuts and Jobs Act (“SAB 118”), which will allow registrants to record provisional amounts during a measurement period. The measurement period is similar to the measurement period used when accounting for business combinations under ASC 805, Business Combinations. SAB 118 allows a registrant to recognize provisional amounts when it does not have the necessary information available, prepared or analyzed (including computations) in reasonable detail to complete its accounting for the change in tax law. Provisional amounts were recorded in prior quarters; however, the measurement period ended as of December 31, 2018 and final amounts ~~are~~were ~~now~~ recorded in the three months ended December 31, 2018. Therefore, no amounts were recognized related to U.S. Tax Reform under SAB 118 for the three months ended March 31, 2019.

19Although these amounts are no longer provisional, the determination of U.S. Tax Reform’s income tax effects may change following future legislation or further interpretation based on the publication of U.S. Treasury regulations as well as guidance from the Internal Revenue Service and state tax authorities. Amounts recognized related to U.S. Tax Reform under SAB 118 for the nine months ended March 31, 2019:

Performance Compensation Incentive Program

During October 2014, ZGH adopted the 2014 Performance Compensation Incentive Program (“PCIP”). The PCIP includes incentive cash compensation and equity in the form of restricted stock units (“RSUs”). Grants under the PCIP RSU plans are made quarterly for all participants. The PCIP was effective on October 16, 2014 and will remain in effect for a period of 10 years (or through October 16, 2024) unless it is earlier terminated by ZGH’s Board of Directors.

~~The PCIP has the following components:~~ 23

Part A

Under Part A of the PCIP, certain full-time employees, including the Company’s executives, are eligible to earn quarterly awards of RSUs. Each participant in Part A of the PCIP will have an RSU annual award target value, which will be allocated to each fiscal quarter. The final Part A value awarded to a participant for any fiscal quarter is determined by the Compensation Committee of the Board of Directors subsequent to the end of the respective performance period taking into account ZGH’s measured value creation for the quarter, as well as such other subjective factors that it deems relevant (including group and individual level performance factors). The number of Part A RSUs granted will be calculated based on the final award value determined by the Compensation Committee divided by the average closing price of ZGH’s common stock over the last ten trading days of the respective performance period. Part A RSUs will vest on the last day of the fifteen month period subsequent to the end of the performance period (for awards relating to quarterly periods through June 30, 2017) or the twelve month period subsequent to the end of the performance period (for awards relating to the quarterly period ended September 30, 2017 and subsequent quarters), subject to continuous employment through such date. Upon vesting, the RSUs convert to an equal number of ZGH’s common stock. Additionally, Part A RSUs may be granted to certain employees upon commencement of their employment with the Company.

During the three and six months ended December 31, 2018, the Company recognized $22.4 million and $45.7 million, respectively, of compensation expense associated with the vested portion of the Part A awards. During the three and six months ended December 31, 2017, the Company recognized $19.4 million and $41.6 million, respectively, of compensation expense associated with the vested portion of the Part A awards. The December 2018 and June 2018 quarterly awards were recorded as liabilities totaling $5.0 million and $5.7 million, as of December 31, 2018 and June 30, 2018, respectively, as the awards represent an obligation denominated in a fixed dollar amount to be settled in a

Part B

Under Part B of the PCIP, participants, including the Company’s executives, are awarded quarterly grants of RSUs. The number of the RSUs earned by the participants is based on ZGH’s stock price performance over a performance period of one year with the starting price being the average closing price over the last ten trading days of the quarter immediately prior to the grant and the ending price being the average closing price over the last ten trading days of the quarter immediately prior to vesting. The RSUs vest on the last day of the twelve month period after the beginning of the performance period (for awards vesting on or prior to June 30, 2018) or the fifteen month period after the beginning of the performance period (for awards vesting after June 30, 2018), subject to continued employment through such date. The existence of a vesting provision that is associated with the performance of ZGH’s stock price is a market condition, which affects the determination of the grant date fair value. Upon vesting, RSUs earned convert to an equal number of shares of ZGH’s common stock.

The Company’s Chief Executive Officer (“CEO”) isand Chief Financial Officer (“CFO”) are also awarded quarterly grants of RSUs under the same provisions as other Part B participants outlined above. However, beginning with the grant during the three months ended December 31, 2018, the CEO’s awards are subject to additional vesting criteria that are based on ZGH’s stock performance subsequent to the end of the measurement period. In order for the CEO to receive the maximum award ZGH’s stock price must remain at or above the ending measurement period price for the six months subsequent to the end of the performance period.

The grant date fair value of Part B RSU grants is estimated utilizing a Monte Carlo simulation. This simulation estimates the ten-day average closing stock price ending on the vesting date, the stock price performance over the performance period, and the number of common shares to be issued at the vesting date. Various assumptions are utilized in the valuation method, including the target stock price performance ranges and respective share payout percentages, the Company’s historical stock price performance and volatility, peer companies’ historical volatility and an appropriate risk-free rate. The aggregate future value of the grant under each simulation is calculated using the estimated per share value of the common stock at the end of the vesting period multiplied by the number of common shares projected to be granted at the vesting date. The present value of the aggregate grant is then calculated under each of the simulations, resulting in a distribution of potential present values. The fair value of the grant is then calculated based on the average of the potential present values. The remaining unrecognized compensation cost associated with Part B RSU grants is $5.9 million at December 31, 2018.

(12) REVENUE AND CONTRACT COSTS

The Company earns revenues from contracts with customers, primarily through the provision of telecommunications and other related offerings. Revenues from leasing arrangements, such as those from dark fiber contracts and colocation facility rental agreements, are not accounted for under ASC 606 . Other revenues are accounted for under ASC 606, which the Company adopted on July 1, 2018, using the full retrospective transition method.

The Company recognizes revenues derived from leasing access to the Company’s fiber optic telecommunications infrastructure and colocation offerings when the offering has been provided and there is persuasive evidence of an arrangement, the fee is fixed or determinable, customer acceptance has been obtained with relevant contract terms, and collection of the receivable is reasonably assured. Taxes collected from customers and remitted to a governmental authority are reported on a net basis and are excluded from revenue.

Most revenue is billed in advance on a fixed-rate basis and the remainder is billed in arrears on a transactional basis determined by customer usage. The Company often bills customers for upfront charges, which are non-refundable. These charges relate to activation fees, installation charges or prepayments for future access or offerings and are influenced by various business factors including how the Company and customer agree to structure the payment terms. These upfront charges are assessed to determine if they represent separate performance obligations or to determine if they provide the customer with a material right (such as discounted pricing on renewals or future orders). A majority of the Company’s upfront payments from customers do not relate to a separate performance obligation, do not provide the customer with a material right and are recognized to revenue ratably over the underlying contract term. Upfront payments that give the customer a right to renew a product offering at a discounted rate are amortized over the period the Company expects to provide the underlying offering.

The Company typically records revenues from leases of dark fiber, including indefeasible rights-of-use (“IRU”) agreements, over the term that the customer is given exclusive access to the assets. Dark fiber IRU agreements generally require the customer to make a down payment upon the execution of the agreement with monthly IRU fees paid over the contract term;. ~~however~~However, in some cases, the Company receives up to the entire lease payment at the inception of the lease and recognizes the revenue ratably over the lease term. Revenue related to professional services to provide network management and technical support is recognized as services are provided.

In determining the appropriate amount of revenue and related reserves to reflect in its consolidated financial statements, management evaluates payment history, credit ratings, customer financial performance, and historical or potential billing disputes and related estimates are based on these factors and assumptions.

Nature of the Company’s Products and Offerings

The Company operates and manages the business in six reportable segments. Revenue is disaggregated by products and offerings, which the Company views as the relevant categorization of revenues for the Company’s businesses. See Note 14 – Segment Reporting, for additional information on the nature of the Company’s ~~Products~~products and ~~Offerings~~offerings by segment.

The Company’s Fiber Solutions and zColo segments have contract terms that are accounted for as leases and are further described below.

Fiber Solutions arrangements are generally fixed rate contracts and can be payable upfront, on a monthly recurring basis or a combination of both. Monthly recurring payment structures in this segment generally include annual inflationary pricing escalators. A majority of the revenue earned from the Fiber Solutions segment is not accounted for under ASC 606 as the contract terms are accounted for as lease arrangements. The Company recognizes revenue associated with its dark fiber leases on a straight-line basis from the customer acceptance date through the lease term.

Table of Contents

ZAYO GROUP, LLC AND SUBSIDIARIES

NOTES TO THE CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)

The Fiber Solutions segment may provide telecommunications construction solutions or perform variable non-routine maintenance activities that are billable to its customers. These types of solutions are accounted for under ASC 606 and are recognized as the service is performed. Revenue recognized from these non-lease arrangements was $915.41 million and $1429.67 million during the three and ~~six~~nine months ended ~~December~~March 31, ~~2018~~2019, respectively, and $56.7 million and $1016.29 million during the three and ~~six~~nine months ended ~~December~~March 31, ~~2017~~2018, respectively.

The Company’s contract terms for the zColo segment includes terms that may be fixed or variable. The Company’s zColo revenue contracts generally include multiple performance obligations including space and infrastructure, which is considered a lease component, and power and remote hand component, which are considered to be separate components of the zColo revenue arrangement. The transaction price in contracts that include multiple performance obligations is allocated to each performance obligation based on the Company’s standalone selling price for each component when such offerings are sold separately. In instances where the Company does not sell the product or offering separately, the Company estimates the standalone selling prices based on observable inputs as well as various market conditions. The Company estimates the standalone selling price to be the price of the offerings when sold on a standalone basis without any promotional discounts.

The Company recognizes revenue on space and infrastructure leases on a straight-line basis over the customer lease term. The Company’s customer leases often include customary renewal terms;. ~~however~~However, the Company does not include any extension options in a customer’s lease term for lease classification purposes or recognizing rental revenue unless it is reasonably certain that the customer will exercise the extension renewal option. The excess of zColo lease revenue recognized in excess of lease payments received is recorded within ~~the~~ other assets on the Company’s condensed consolidated balance sheets.

Customer power arrangements are coterminous with the respective customer lease and may be billed at fixed or variable rates. The Company recognizes revenue on its fixed rate power contracts as the arrangements are rendered, as the customer simultaneously receives and consumes the benefit of the arrangements provided. Variable contracts are invoiced based on usage and are billed in arrears and recognized as the usage occurs. Revenue is recognized on remote hand services as the services are provided. Revenue recognized by the zColo segment from these non-lease arrangements was $13.97 million and $2842.41 million during the three and ~~six~~nine months ended ~~December~~March 31, ~~2018~~2019, respectively, and was $14.53 million and $2842.69 million during the three and ~~six~~nine months ended ~~December~~March 31, ~~2017~~2018, respectively.

Contracts in the Company’s zColo segment do not include significant financing components.

The Company’s contract terms for Transport, Enterprise Networks, Allstream and Other segments include terms that may be fixed or variable. The Company recognizes revenue on its fixed rate contracts as the product offerings are rendered, as the customer simultaneously receives and consumes the benefit of the products provided. Variable contracts are invoiced based on usage and are billed in arrears and recognized as the usage occurs. These contracts do not include significant financing components and generally include a single performance obligation. The transaction price in contracts that include multiple performance obligations is allocated to each performance obligation based on the Company’s standalone selling price for each product offering. The Company estimates the standalone selling price to be the price of the offering when sold on a standalone basis without any promotional discounts.

The Company may provide performance-based credits associated with the solution it offers, which are accounted for as variable consideration when estimating the transaction price. Credits are estimated at contract inception and are updated at the end of each reporting period as additional information becomes available. The assessment of this variable consideration involves judgment and impacts the Company’s determination of transaction price and related disclosures.

Remaining Performance Obligation Associated with Non-Lease Arrangements

A majority of the Company’s revenue is provided over a contract term. When allocating the total contract transaction price to identified performance obligations, a portion of the total transaction price relates to performance obligations that are yet to be satisfied or are partially satisfied as of the end of the reporting period.

27In determining the transaction price allocated to remaining performance obligations, the Company does not include non-recurring charges and estimates for usage.

Contract Assets and Liabilities

The timing of revenue recognition may differ from the time of billing to the Company’s customers. Customer receivables represent an unconditional right to consideration net of an estimated allowance for doubtful accounts. Contract balances represent amounts from an arrangement when either the Company has performed, by transferring a solution to the customer in advance of receiving all or partial consideration for such goods and offerings from the customer, or the customer has made payment to the Company in advance of obtaining control of the goods and/or offerings promised to the customer in the contract.

Contract liabilities arise when the Company bills its customers and receives consideration in advance of providing the goods or offerings promised in the contract. Contract liabilities are recognized as revenue when product offerings are provided to the customer. Contract liabilities are presented in the Company’s condensed consolidated balance sheet as deferred revenue.

The following table presents information about the Company’s customer receivables, contract assets and contract liabilities as of ~~December~~March 31, ~~2018~~2019 and June 30, 2018:

Contract Costs

The Company recognizes an asset for incremental commission and bonus expenses paid to internal sales personnel and third party agents in conjunction with obtaining certain customer contracts. These costs are only deferred when the commissions are incremental and would not have been incurred absent the customer contract. Costs to obtain a contract are amortized and recorded ratably within selling, general and administrative expenses on the Company’s condensed consolidated statements of operations over the estimated contract term.

The Company also defers costs incurred to fulfill contracts that relate directly to the contract, are expected to generate resources that will be used to satisfy the Company’s performance obligation under the contract and are expected to be recovered through revenue generated under the contract. Contract fulfillment costs are expensed to cost of service as the Company satisfies its performance obligations. These costs principally relate to direct costs associated with activating new customer solutions.

The Company estimates the amortization period for its costs incurred to obtain and fulfill customer contracts at a portfolio level due to the similarities within its customer contract portfolios.

Other costs, such as general costs or costs related to past performance obligations, are expensed as incurred.

As of ~~December~~March 31, ~~2018~~2019 and June 30, 2018, the Company had $6.10 million and $7.1 million, respectively, of short-term unamortized contract costs included in other current assets and $4.32 million and $5.6 million, respectively, of long term unamortized ~~contact~~ contract costs included in other assets on its condensed consolidated balance sheets. During the three and ~~six~~nine months ended ~~December~~March 31, ~~2018~~2019, the Company recorded $12.81 million and $36.90 million, respectively, in selling, general and administrative expenses associated with the amortization of deferred contract costs. During the three and ~~six~~nine months ended ~~December~~March 31, ~~2017~~2018, the Company recorded $2.13 million and $46.36 million, respectively, in selling, general and administrative expenses associated with the amortization of deferred contract costs. The amortization period for these contract costs ranges from 12 to 5451 months.

(14) SEGMENT REPORTING

The Company uses the management approach to determine the segment financial information that should be disaggregated and presented separately in the Company's notes to its condensed consolidated financial statements. The management approach is based on the manner by which management has organized the segments within the Company for making operating decisions, allocating resources, and assessing performance.

As the Company has increased in scope and scale, it has developed its management and reporting structure to support this growth. The Company’s bandwidth infrastructure, colocation and connectivity offerings are comprised of various related product groups generally defined around the type of offering to which the customer is licensing access, referred to as SPGs. Each SPG is responsible for the revenue, costs and associated capital expenditures of its respective solutions. The SPGs enable licensing and sales, make pricing and product decisions, engineer networks and deliver solutions to customers, and support customers for specific telecom and Internet infrastructure requirements.

During Fiscal 2018, with the continued increase in its scope and scale, the Company’s chief operating decision maker ("CODM"), who is the Company’s Chief Executive Officer, implemented certain organizational changes to the management and operation of the business that directly impact how the CODM makes resource allocation decisions and manages the Company. The changes in structure had the impact of creating two new SPGs and re-aligning an existing SPG among the Company’s reportable segments. The changes in structure also resulted in changes in how the Company measures the relative burden each segment bears of indirect and corporate related costs.

Effective April 1, 2018 the Company’s Ethernet SPG, previously reported under the Enterprise Networks segment, is now reported under the Company’s Transport segment. Additionally, certain activities and operations of the legacy Waves, WAN, and Ethernet SPGs were combined to form a new SPG, CloudLink. These changes to the existing reportable segments (the “Realignment”) have been recast for all prior period financial and operating metrics presented in this Quarterly Report on Form 10-Q for comparability, such as;

· Certain activities and operations of the legacy Waves, WAN, and Ethernet SPGs, after giving effect to the Realignment, are now reported in a new SPG, CloudLink, under the Enterprise Networks segment; and  The wholesale IP services and Sonet SPGs, and the remaining activities and operations of the legacy Waves and Ethernet SPGs (the activities and operations not related to CloudLink), after giving effect to the Realignment, are now reported under the Transport segment.

· The wholesale IP services and Sonet SPGs, and the remaining activities and operations of the legacy Waves and Ethernet SPGs (the activities and operations not related to CloudLink), after giving effect to the Realignment, are now reported under the Transport segment.

In addition to the changes in structure, the Company also adjusted intercompany pricing methodologies to more closely align to third party pricing on the products and offerings which are exchanged between our SPGs. However, it was not practicable to retrospectively present the impact of this change for all historical periods presented.

The Company’s segments are further described below:

Fiber Solutions. The Fiber Solutions segment offers access to raw bandwidth infrastructure to customers that require control of their internal networks. These solutions include dark fiber, dedicated lit network sections and mobile infrastructure (fiber-to-the-tower and small cell). Dark fiber is a physically separate and secure, private platform for dedicated bandwidth. The Company leases dark fiber pairs (usually 2 to 12 total fibers) to customers, who “light” the fiber using their own optronics. The Company’s mobile infrastructure solutions permit direct fiber connections to cell towers, small cells, hub sites, and mobile switching centers. Fiber Solutions customers include carriers and other communication service providers, Internet service providers, wireless service providers, major media and content companies, large enterprises, and other companies that have the expertise to run their own fiber optic networks or require interconnected technical space. The contract terms in the Fiber Solutions segment tend to range from three to twenty years.

Transport. The Transport segment provides access to lit bandwidth infrastructure solutions over metro, regional, and long-haul fiber network sections. The segment uses customer-accessed optronics to light the fiber, and the Company’s customers pay for access based on the amount and type of bandwidth they require. The offerings within this segment include Wavelengths, Ethernet, SONET, and wholesale IP offerings. The Company targets customers who require a minimum of 10G of bandwidth across their networks. Transport customers include carriers, content providers, financial services companies, healthcare, government entities,

3032

Table of Contents

ZAYO GROUP, LLC AND SUBSIDIARIES

NOTES TO THE CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)

education institutions and other medium and large enterprises. The contract terms in this segment tend to range from two to five years.

Enterprise Networks. The Enterprise Networks segment provides connectivity and telecommunications solutions to medium and large enterprises. The offerings within this segment include Internet, wide area networking products, managed products and cloud based computing and storage offerings. Solutions range from point-to-point data connections to multi-site managed networks to international outsourced IT infrastructure environments. The contract terms in the Enterprise Networks segment tend to range from one to ten years.

Zayo Colocation (“zColo”). The Colocation segment provides data center infrastructure solutions to a broad range of enterprise, carrier, cloud, and content customers. The offerings within this segment include the provision of colocation space, power and interconnection offerings in North America and Western Europe. Solutions range in size from single cabinet solutions to 1MW+ data center infrastructure environments. The Company’s data centers also support a large component of networking components for the purpose of aggregating and accommodating customers’ data, voice, Internet, and video traffic. The contract terms in this segment tend to range from two to five years.

Allstream. The Allstream segment provides Cloud VoIP and Data Solutions. This includes a full range of local voice offerings allowing business customers to complete telephone calls in their local exchange, as well as make long distance, toll-free and related calls. Unified Communications is the integration of real-time communication services such as telephony (including Cloud-based IP telephony), instant messaging and video conferencing with non-real-time communication services, such as integrated voicemail and e-mail. Allstream also provides customers with comprehensive telecommunications services, including Ethernet, and IP/MPLS VPN Solutions.

Other. The Other segment is primarily comprised of Zayo Professional Services (“ZPS”). ZPS provides network and technical resources to customers who wish to leverage the Company’s expertise in designing, acquiring and maintaining network sections. The contract terms typically run for one year for a fixed recurring monthly fee in the case of network and on an hourly basis for technical resources (usage revenue). ZPS also generates revenue via telecommunication equipment sales.

The results of operations for each segment include an allocation of certain indirect costs and corporate related costs, including overhead and third party-financed debt. The allocation is based on a percentage that represents management’s estimate of the relative burden each segment bears of indirect and corporate costs. Management has evaluated the allocation methods utilized to allocate these costs and determined they are systematic, rational and consistently applied. Identifiable assets for each reportable segment are reconciled to total consolidated assets including unallocated corporate assets and intersegment eliminations. Corporate assets consist primarily of cash and deferred taxes.

In connection with the Company’s acquisition of Electric Lightwave Parent, Inc., the Company acquired certain customer contracts that included the bundled provision of VoIP and data connectivity solutions. This bundled package was historically managed and reported as revenue by the Enterprise Networks segment. Subsequent to June 30, 2018, operational changes were made which resulted in the management of these bundled contracts to be provided by the Allstream segment and as such a portion of the revenue associated with these contracts ~~will~~are now be reported as revenue of the Allstream segment. The Enterprise Networks segment continues to own the infrastructure and equipment that supports these contracts and as such the segments entered into an intercompany agreement for the continued use of these assets, which will result in the recognition of intercompany revenue at the Enterprise Networks segment. Management determined it was impracticable to retrospectively present the impacts of this change to historical periods. This change increased Allstream’s Segment Adjusted EBITDA for the three and ~~six~~nine months ended ~~December~~March 31, ~~2018~~2019 by $0.7 million and $12.41 million, respectively, and decreased Enterprise’s Segment Adjusted EBITDA for the three and ~~six~~nine months ended ~~December~~March 31, ~~2018~~2019 by $0.7 million and $12.41 million, respectively.

~~Effective~~ We ~~January~~continue 1,to ~~2019~~make certain operational changes ~~were~~that ~~made~~we ~~which~~expect to change the way the CODM makes resource allocation decisions and manages the Company (originally anticipated and previously disclosed to be effective January 1, 2019). As such, ~~beginning~~we ~~with~~expect for the quarter ending ~~March~~June 3130, 2019, the Company will have four reportable segments: Zayo Networks, ~~Colo~~zColo, Allstream and Other. The Company will recast its prior period financial and operating metrics ~~presented in previous filings to reflect the financial results of the Company’s~~

NOTES TO THE CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)

presented in previous filings to reflect the financial results of the Company’s new segment structure in its ~~quarterly~~annual report for ~~the~~Fiscal ~~quarter ending March 31,~~ 2019. The change will not have an impact on consolidated revenues, EBITDA, capital expenditures or assets.

Segment Adjusted EBITDA

Segment Adjusted EBITDA is the primary measure used by the Company’s CODM to evaluate segment operating performance.

The Company defines Segment Adjusted EBITDA as earnings/(loss) from operations before interest, income taxes, depreciation and amortization (“EBITDA”) adjusted to exclude acquisition or disposal-related transaction costs, losses on extinguishment of debt, stock-based compensation, unrealized foreign currency gains/(losses) on intercompany loans, gains/(losses) on business dispositions and non-cash income/(loss) on equity and cost method investments. The Company uses Segment Adjusted EBITDA to evaluate operating performance, and this financial measure is among the primary measures used by management for planning and forecasting of future periods. The Company believes ~~that~~ the presentation of Segment Adjusted EBITDA is relevant and useful for investors because it allows investors to view results in a manner similar to the method used by management and facilitates comparison of the Company’s results with the results of other companies that have different financing and capital structures.

Segment Adjusted EBITDA results, along with other quantitative and qualitative information, are also utilized by the Company and its Compensation Committee for purposes of determining bonus payouts to employees.

Segment Adjusted EBITDA has limitations as an analytical tool and should not be considered in isolation from, or as a substitute for, analysis of the Company’s results from operations and operating cash flows as reported under GAAP. For example, Segment Adjusted EBITDA:

			does not reflect capital expenditures, or future requirements for capital and major maintenance expenditures or contractual commitments;
			does not reflect changes in, or cash requirements for, working capital needs;
			does not reflect the significant interest expense, or the cash requirements necessary to service the interest payments, on the Company’s debt; and
			does not reflect cash required to pay income taxes.

The Company’s computation of Segment Adjusted EBITDA may not be comparable to other similarly titled measures computed by other companies because all companies do not calculate segment Adjusted EBITDA in the same fashion.

dedicated wavelength connections, Ethernet, IP connectivity, cloud-based computing and storage products and other high-bandwidth offerings. We provide access to our bandwidth infrastructure and other offerings over a unique set of dense metro, regional, and long-haul fiber network sections and through our interconnect-oriented data center facilities. Our fiber network sections and data center facilities are critical components of the overall physical network architecture of the Internet and private networks. Our customer base includes some of the largest and most sophisticated users of bandwidth infrastructure, such as wireless service carriers; telecommunications service carriers; financial services companies; social networking, media, and web content companies; education, research, and healthcare institutions; and governmental agencies. We typically provide customers with access to our bandwidth infrastructure solutions for a fixed monthly recurring fee under contracts that vary between one and twenty years in length. We operate our business with a unique focus on capital allocation and financial performance with the ultimate goal of maximizing equity value for ~~Zayo Group Holdings, Inc. (“~~ZGH”) stockholders. Our core values center on partnership, alignment, and transparency with our three primary constituent groups – employees, customers, and ZGH stockholders.

We are a wholly-owned subsidiary of ~~Zayo Group Holdings~~ZGH, ~~Inc.,~~ a Delaware corporation, which prior to October 16, 2014, was wholly owned by Communications Infrastructure Investments, LLC, a Delaware limited liability company (“CII”). We are headquartered in Boulder, Colorado.

Our fiscal year ends June 30 each year, and we refer to the fiscal year ending June 30, 2019 as “Fiscal 2019” and the fiscal year ended June 30, 2018 as “Fiscal 2018.”

We are headquartered in Boulder, Colorado.

Reportable Segments and our Strategic Product Groups

We use the management approach to determine the segment financial information that should be disaggregated and presented. The management approach is based on the manner by which management has organized the segments within the Company for making operating decisions, allocating resources, and assessing performance. ~~With~~During Fiscal 2018, with the continued increase in ~~our~~ its scope and scale, ~~effective~~ ~~April 1, 2018,~~ our chief operating decision maker ("CODM"), who is our Chief Executive Officer, implemented certain organizational changes to the management and operation of the business that directly impact how the CODM makes resource allocation decisions and manages ~~the Company~~us. The change in structure had the impact of re-aligning our existing Strategic Product Groups (“SPGs”) within our existing segments. The changes in structure also resulted in changes in how ~~the~~we ~~Company~~measure ~~measures~~ the relative burden each segment bears of indirect and corporate related costs, and in adjustments to intercompany pricing that more closely align to third party pricing on the products and offerings which are exchanged between our SPGs. See Note 1314 – Segment Reporting, in our condensed consolidated financial statements for further description of the changes. Where practicable, changes to all prior period financial and operational metrics have been recasted in our quarterly report for comparability. We have six reportable segments as described below:

Fiber Solutions. Through the Fiber Solutions segment, we provide access to raw bandwidth infrastructure to customers that require control of their internal networks. These solutions include dark fiber, dedicated lit network sections and mobile infrastructure (fiber-to-the-tower and small cell). Dark fiber is a physically separate and secure, private platform for dedicated bandwidth. We lease dark fiber pairs (usually 2 to 12 total fibers) to our customers, who “light” the fiber using their own optronics. Our mobile infrastructure solutions permit direct fiber connections to cell towers, small cells, hub sites, and mobile switching centers. Fiber Solutions customers include carriers and other communication service providers, Internet service providers, wireless service providers, major media and content companies, large enterprises, and other companies that have the expertise to run their own fiber optic networks or require interconnected technical space. The contract terms in the Fiber Solutions segment tend to range from three to twenty years.

Transport. The Transport segment provides access to lit bandwidth infrastructure solutions over our metro, regional, and long-haul fiber network sections. The segment uses customer-accessed optronics to light the fiber, and our customers pay for access based on the amount and type of bandwidth they require. The offerings within this segment include Wavelengths, Ethernet, SONET, and wholesale IP. We target customers who require a significant amount of bandwidth across their networks. Transport customers include carriers, content providers, financial services companies, healthcare, government entities, education ~~institutions and other medium and large enterprises. The contract terms in this segment tend to range from two to five years.~~

Enterprise Networks. The Enterprise Networks segment provides connectivity and lit bandwidth telecommunication solutions to medium and large enterprises. Our offerings within this segment include Internet, wide area networking products, managed products and cloud-based computing and storage offerings. Solutions range from point-to-point data connections to multi-site managed networks to 47

~~international~~institutions ~~outsourced~~and ITother ~~infrastructure~~medium ~~environments~~and large enterprises. The contract terms in ~~the~~this ~~Enterprise Networks~~ segment tend to range from ~~one~~two to ~~ten~~five years.

Zayo Colocation (zColo). The Colocation segment provides data center infrastructure solutions to a broad range of enterprise, carrier, cloud, and content customers. Our offerings within this segment include the provision of colocation space, power and interconnection offerings in North America and Western Europe. Solutions range in size from single cabinet solutions to 1MW+ data center infrastructure environments. Our data centers also support a large component of networking components for the purpose of aggregating and accommodating customer’s data, voice, Internet, and video traffic. The contract terms in this segment tend to range from two to five years.

Other. Our Other segment is primarily comprised of Zayo Professional Services (“ZPS”). ZPS provides network and technical resources to customers who wish to leverage our expertise in designing, acquiring and maintaining network sections. The contract terms typically run for one year for a fixed recurring monthly fee in the case of network and on an hourly basis for technical resources (usage revenue). ZPS also generates revenue via telecommunication equipment sales.

~~Effective~~We ~~January~~continue 1,to ~~2019~~make certain operational changes ~~were~~that ~~made~~we ~~which~~expect to change the way the CODM makes resource allocation decisions and manages the Company (originally anticipated and previously disclosed to be effective January 1, 2019). As such, ~~beginning~~we ~~with~~expect for the quarter ending ~~March~~June 3130, 2019, the Company will have four reportable segments: Zayo Networks, ~~Colo~~zColo, Allstream and Other. The Company will recast its prior period financial and operating metrics presented in previous filings to reflect the financial results of the Company’s new segment structure in its ~~quarterly~~annual report for ~~the~~Fiscal ~~quarter ending March 31,~~ 2019. The change will not have an impact on consolidated revenues, EBITDA, capital expenditures or assets.

Evaluation and Preparation for Potential REIT Conversion

On May 3, 2018, we announced that we completed the first phase of our investigation on the advisability and feasibility of a conversion of ZGH to a ~~real estate investment trust for U.S. federal income tax purposes (a “~~REIT”). We have begun the next phase of our evaluation and preparation for a potential conversion to a REIT. As part of these efforts, we have begun a direct dialogue with the U.S. Internal Revenue Service (“IRS”) in an effort to obtain clarity and support for our position, and ZGH is seeking a private letter ruling (“PLR”) from the IRS. Also, we have begun to execute the organizational changes that are required for ZGH to operate as a REIT, including the adoption of certain amendments to our organizational documents that, among other things, impose certain stock ownership limitations and transfer restrictions, the realignment of our business segments to clearly delineate the leasing of network assets from ancillary services and, in particular, the separation and potential divestiture or deconsolidation of our Allstream business segment. These organizational changes do not result in any changes to our reportable segments.

If, following our current phase of evaluation and preparation, we decide to convert ZGH to a REIT and are successful in qualifying ZGH for taxation as a REIT, we will generally be permitted to deduct from federal income taxes the dividends that ZGH pays to its stockholders. The income represented by such dividends would not be subject to federal income taxation at the entity level but would be taxed, if at all, at the stockholder level. Nevertheless, the income of ZGH’s domestic taxable REIT subsidiaries (each, a “TRS”), which will hold our U.S. operations that may not be REIT-compliant, will be subject, as applicable, to federal and state corporate income tax. Likewise, our foreign subsidiaries will continue to be subject to foreign income taxes in jurisdictions in which they hold assets or conduct operations, regardless of whether held or conducted through TRSs or through entities that are disregarded from us for U.S. federal income tax purposes. Also, we will be subject to a separate corporate income tax on any gains recognized during a specified period (generally 5 years) following the REIT conversion that are attributable to “built-in” gains with respect to the assets that we own on the date ZGH converts to a REIT.

REIT-compliant, will be subject, as applicable, to federal and state corporate income tax. Likewise, our foreign subsidiaries will continue to be subject to foreign income taxes in jurisdictions in which they hold assets or conduct operations, regardless of whether held or conducted through TRSs or through entities that are disregarded from us for U.S. federal income tax purposes. Also, we will be subject to a separate corporate income tax on any gains recognized during a specified period (generally 5 years) following the REIT conversion that are attributable to “built-in” gains with respect to the assets that we own on the date ZGH converts to a REIT.

The ability of ZGH to qualify for taxation as a REIT will depend upon our continuing compliance following the REIT conversion with various requirements, including requirements related to the nature of our assets, the sources of our income and the distributions to ZGH stockholders. If ZGH fails to qualify for taxation as a REIT, we will be subject to federal income tax at regular corporate income tax rates. Even if ZGH qualifies for taxation as a REIT, we may be subject to certain federal, state, local and foreign taxes on our income and property. In particular, while state income tax regimes often parallel the federal income tax regime for REITs described above, many states do not completely follow federal rules and some may not follow them at all.

The current phase of our evaluation and preparation currently includes ZGH seeking a PLR from the IRS. We are requesting that the PLR address whether our revenues from dark and lit fiber satisfy applicable REIT income tests, and our ultimate decision to convert ZGH to a REIT may depend upon a favorable ruling from the IRS on this topic. ZGH submitted the PLR request to the IRS in July 2018, but the IRS may not provide a response until later in 2019 or later or may not respond at all.

At this stage of our evaluation and preparation for a potential conversion of ZGH to a REIT, we cannot accurately estimate the costs required to support any potential conversion, but we anticipate that our costs would include various administrative costs in addition to certain related tax liabilities.

Factors Affecting Our Results of Operations

Business Acquisitions

We were founded in 2007 with the investment thesis of building a bandwidth infrastructure platform to take advantage of the favorable Internet, data, and wireless growth trends driving the ongoing demand for access to bandwidth infrastructure, and to be an active participant in the consolidation of the industry. These trends have continued in the years since our founding, despite volatile economic conditions, and we believe that we are well positioned to continue to capitalize on those trends. We have built a significant portion of our network and product offerings through 45 acquisitions through ~~December~~March 31, ~~2018~~2019.

As a result of the growth of our business from these acquisitions, and the capital expenditures and increased debt used to fund those investing activities, our results of operations for the respective periods presented and discussed herein are not comparable.

Recent Acquisitions

Neutral Path Communications

On April 17, 2018, we acquired substantially all of the assets of Neutral Path Communications and Near North Partners (collectively, “Neutral Path”) for $33.3 million, which is net of cash acquired and also included an estimate for a contingent payment based on sales performance through June 30, 2018. The purchase price is subject to net working capital and certain post-closing adjustments. As of ~~December~~March 31, ~~2018~~2019, $4.0 million of the purchase consideration is being held in escrow pending the expiration of the indemnification adjustment period. The all-cash acquisition was funded with cash on hand and was considered an asset purchase for U.S. federal income tax purposes.

Neutral Path is a long haul infrastructure provider, providing access to a fiber network section in the Midwest. The transaction added 452 owned route miles, plus additional leased route miles, to our extensive North American network, including a unique high-count fiber route from Minneapolis to Omaha. The fiber footprint augments our network with three owned diverse fiber routes out of Minneapolis, Chicago and Omaha.

The results of the acquired Neutral Path business are included in our operating results beginning April 17, 2018.

Spread Networks

On February 28, 2018, we acquired Spread Networks, LLC (“Spread Networks”), a privately-owned telecommunications provider that owns and offers access to a 825-mile, high-fiber count long haul route connecting New York and Chicago, for net purchase consideration of $130.5 million, net of cash acquired, subject to certain post-closing adjustments. AsDuring ofthe ~~December~~three months ended March 31, ~~2018~~2019, ~~$0.6 million of~~ the ~~purchase~~indemnification ~~consideration~~adjustment isperiod ~~being~~expired ~~held~~and inthe ~~escrow~~final ~~pending~~distribution ~~the~~of ~~expiration~~$0.6 million of the ~~indemnification~~indemnity ~~adjustment~~escrow ~~period~~fund was made. The all-cash acquisition was funded with cash on hand and was considered an asset purchase for U.S. federal income tax purposes.

The route connects 755 Secaucus Road in Secaucus, New Jersey and 1400 Federal Boulevard in Carteret, New Jersey to 350 Cermak Road in Chicago, Illinois, with additional connectivity to be enabled by Zayo’s existing network. Zayo plans to use the acquired assets to provide a low-latency wavelength route from Seattle to New York.

The results of the acquired Spread Networks business are included in our operating results beginning February 28, 2018.

Optic Zoo Networks

On January 18, 2018, we acquired Vancouver, BC Canada-based Optic Zoo Networks for net purchase consideration of CAD $30.9 million (or $24.8 million), net of cash acquired, subject to certain post-closing adjustments. Optic Zoo Networks owns and provides access to high-capacity fiber in Vancouver. As of ~~December~~March 31, ~~2018~~2019, CAD $3.1 million (or $2.3 million), of the purchase consideration is being held in escrow pending the expiration of the indemnification adjustment period. The acquisition was funded with cash on hand and was considered a stock purchase for U.S. federal income tax purposes.

The transaction strengthens Zayo’s position in Vancouver and Western Canada, adding 103 route miles and more than 100 on-net buildings to Zayo’s Vancouver footprint.

The results of the acquired Optic Zoo Networks business are included in our operating results beginning January 18, 2018.

Disposition

Scott-Rice Telephone Co.

On July 31, 2018, we completed the sale of Scott-Rice Telephone Co. (“SRT”), a Minnesota incumbent local exchange carrier, for $42.2 million to Nuvera Communications, Inc. (formerly New Ulm Telecom, Inc.). As of ~~December~~March 31, ~~2018~~2019, $3.2 million of purchase consideration was held in escrow. We recognized a pre-tax gain of $5.5 million on the sale, which is included in other income, net in the condensed consolidated statements of operations. We acquired SRT as part of our March 1, 2017 purchase of Electric Lightwave Parent, Inc. and it was included as part of the Allstream segment. SRT had a pre-tax net loss of $1.6 million for the year ended June 30, 2018 and pre-tax net income of $2.9 million from when it was acquired in March 1, 2017 through June 30, 2017.

Critical Accounting Policies and Estimates

For a description of our critical accounting policies and estimates, see “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in our Annual Report for the year ended June 30, 2018.

Background for Review of Our Results of Operations

Revenue

Our revenue is comprised predominately of monthly recurring revenue (“MRR”). MRR is related to an ongoing offering that is generally fixed in price and paid by the customer on a monthly basis. We also report monthly amortized revenue (“MAR”), which represents the amortization of previously collected upfront charges to customers. Upfront charges are typically related to indefeasible rights of use (“IRUs”) structured as pre-payments rather than monthly recurring payments (though we structure IRUs as both prepaid and recurring, largely dependent on the customers’ preference) and installation fees. The last category of revenue we report is other revenue. Other revenue primarily includes credits and adjustments, termination revenue, construction contribution payments, and component sales.

4851

Table of Contents

Our consolidated reported revenue in any given period is a function of our beginning revenue under contract and the impact of organic growth and acquisition activity. Our organic activity is driven by net new sales (“bookings”), gross installed revenue (“installs”) and churn processed (“churn”) as further described below.

Net New Sales. Net new sales (“bookings”) represent the dollar amount of orders, to be recorded as MRR and MAR upon installation, in a period that have been signed by the customer and accepted by our product offering delivery organization. The dollar value of bookings is equal to the monthly recurring price that the customer will pay for the offerings and/or the monthly amortized amount of the revenue that we will recognize for those offerings. To the extent a booking is cancelled by the customer prior to the offerings being originated, it is subtracted from the total bookings number in the period that it is cancelled. Bookings do not immediately impact revenue until the solutions are installed (gross installed revenue).

Gross Installed Revenue. Installs are the amount of MRR and MAR for offerings that have been installed, tested, accepted by the customer, and have been recognized in revenue during a given period. Installs include new offerings, price increases, and upgrades.

Churn Processed. Churn is any negative change to MRR and MAR. Churn includes disconnects, negative price changes, and disconnects associated with upgrades or replacement offerings. For each period presented, disconnects associated with attrition and upgrades or replacement offerings are the drivers of churn, accounting for more than 75% of negative changes in MRR and MAR, while price changes account for less than 25%. Monthly churn is also presented as a percentage of MRR and MAR (“churn percentage”).

Given the size and amount of acquisitions we have completed, we have estimated the revenue growth rate associated with our organic activity in each period reported. Our estimated organic growth rate is calculated as if acquisitions closed during the periods presented were closed on the first day of the earliest period presented within this Quarterly Report. In calculating this pro-forma growth figure, we add the revenue recorded by the acquired companies (including estimated purchase accounting adjustments) for the reporting periods prior to the date of inclusion in our results of operations and then calculate the growth rate between the two reported periods. The estimated pro-forma revenue growth rates are not necessarily indicative of either future results of operations or results that might have been achieved had the acquisitions been consummated on the first day of the earliest period presented. As we conduct operations outside of the U.S. and have historically acquired companies with functional currencies other than the U.S. dollar (“USD”), the estimated pro-forma revenue growth rates may not adequately reflect operational performance as a result of changes in foreign currency exchange rates.

We have foreign subsidiaries that enter into contracts with customers and vendors in currencies other than the USD, – principally the British pound sterling (“GBP”) and Canadian dollar (“CAD”) and to a lesser extent the Euro. Changes in foreign currency exchange rates impact our revenue and expenses each period. The comparisons excluding the impact of foreign currency exchange rates assume exchange rates remained constant at the comparative period rate.

Operating Costs and Expenses

Our operating costs and expenses consist of network expense (“Netex”), compensation and benefits, network operations expense (“Netops”), stock-based compensation expense, other expenses, and depreciation and amortization.

Netex consists of third-party network costs resulting from our leasing of certain network facilities, primarily leases of circuits and dark fiber, from third parties to augment our owned infrastructure, for which we are generally billed a fixed monthly fee. Netex also includes colocation facility costs for rent and license fees paid to the landlords of the buildings in which our colocation business operates, along with the utility costs to power those facilities. While increases in demand for our offerings will drive additional operating costs in our business, consistent with our strategy of leveraging our owned infrastructure assets, we expect to primarily utilize our existing network infrastructure or build new network infrastructure to meet the demand. In limited circumstances, we will augment our network with additional infrastructure or offerings from third-party providers. Third-party network costs include the upfront cost of the initial installation of such infrastructure. Such costs are included in operating costs in our condensed consolidated statements of operations over the respective contract period.

Compensation and benefits expenses include salaries, wages, incentive compensation and benefits. Employee-related costs that are directly associated with network construction and location installations (and development of business support systems) are capitalized and amortized to operating costs and expenses. Compensation and benefits

Table of Contents

expenses related to the departments attributed to generating revenue are included in our operating costs line item while compensation and benefits expenses related to the sales, product, and corporate departments are included in our selling, general and administrative expenses line item of our condensed consolidated statements of operations.

Netops expense includes all of the non-personnel related expenses of operating and maintaining our network infrastructure, including contracted maintenance fees, right-of-way costs, rent for cellular towers and other places where fiber is located, pole attachment fees, and relocation expenses. Such costs are included in operating costs in our condensed consolidated statements of operations.

Stock-based compensation expense is included, based on the responsibilities of the awarded recipient, in either our operating costs or selling, general and administrative expenses in our condensed consolidated statements of operations.

Other expenses include expenses such as property tax, franchise fees, colocation facility maintenance, travel, office expense and other administrative costs. Other expenses are included in both operating costs and selling, general and administrative expenses depending on their relationship to generating revenue or association with sales and administration.

Transaction costs include expenses associated with professional services (i.e. legal, accounting, regulatory, etc.) rendered in connection with acquisitions or disposals (including spin-offs), travel expense, and severance expense incurred that are associated with acquisitions or disposals, and other direct expenses incurred that are associated with signed and/or closed acquisitions or disposals and unsuccessful acquisitions. Transaction costs are included in “selling, general and administrative expenses” in our condensed consolidated statements of operations.

Provision for Income Taxes

On December 22, 2017, the U.S. federal government enacted a tax bill, H.R.1, An Act to Provide for Reconciliation Pursuant to Titles II and V of the Concurrent Resolution on the Budget for Fiscal Year 2018, previously known as ~~the~~ Tax Cuts and Jobs Act of 2017 (“U.S. Tax Reform”). U.S. Tax Reform reduced the U.S. corporate tax rate ~~from 35% to 21%, created a territorial tax system with a one-time mandatory repatriation tax on previously deferred foreign earnings, and changed business-related deductions and credits.~~

ASC 740, Income Taxes, requires companies to recognize the effect of tax law changes in the period of enactment. The SEC staff issued SAB 118, Income Tax Accounting Implications of the Tax Cuts and Jobs Act (“SAB 118”), which will allow registrants to record provisional amounts during a ‘measurement period.’ The measurement period is similar to the measurement period used when accounting for business combinations under ASC 805, Business Combinations. SAB 118 allows a registrant to recognize provisional amounts when it does not have the necessary information available, prepared or analyzed (including computations) in reasonable detail to complete its accounting for the change in tax law. Provisional amounts were recorded in prior quarters; however, the measurement period ended as of December 31, 2018 and final amounts are now recorded.56

~~Our~~Table ~~provision~~of for income taxes increased over the same quarter in the prior year by $2.1 million to $22.5 million for the three months ended December 31, 2018 from $20.4 million for the three months ended December 31, 2017. Our provision for income taxes included both the current provision and a provision for deferred income tax expense resulting from timing differences between tax and financial reporting accounting bases.

Some U.S. Tax Reform provisions are effective beginning this fiscal year. As of March 31, 2019, the following provisions are not expected to have a material impact on tax expense: Global Intangible Low-Taxed Income (GILTI), Base Erosion and Anti-abuse Tax (BEAT), and the interest expense limitations. For the three months ended March 31, 2019, the executive compensation limitations had an immaterial impact. We continue to evaluate the impact of U.S. Tax Reform as more information and guidance becomes available.

Our provision for income taxes decreased over the same quarter in the prior year by $3.0 million to $18.0 million for the three months ended March 31, 2019 from $21.0 million for the three months ended March 31, 2018. Our provision for income taxes included both the current provision and a provision for deferred income tax expense resulting from timing differences between tax and financial reporting accounting bases.

The following table reconciles an expected tax provision based on a statutory federal tax rate applied to our earnings before income tax to our actual provision for income taxes:

We estimate that the period-over-period pro-forma organic revenue decrease was approximately 2.40%. Our pro-forma revenue decline was primarily driven by changes in exchange rates. The average exchange rate of the GBP against the USD weakened by 13.84%, the average exchange rate of the Euro against the USD weakened by 24.10%, and the average exchange rate of the CAD against the USD weakened by 4.03% during the ~~six~~nine months ended ~~December~~March 31, ~~2018~~2019 as compared to the ~~six~~nine months ended ~~December~~March 31, ~~2017~~2018. We estimate that pro-forma revenue was negatively impacted by foreign currency exchange fluctuations between the ~~six~~nine months ended ~~December~~March 31, ~~2018~~2019 and ~~December~~March 31, ~~2017~~2018 by $921.81 million for a total period-over-period pro-forma organic revenue decline of approximately 1.61%.
