Discussion of Non-GAAP Financial Measures
Ribbon Communications’ management uses several different financial measures, both GAAP and non-GAAP, in analyzing and assessing the overall performance of the business, making operating decisions, planning and forecasting future periods, and determining payments under compensation programs.  Our annual financial plan is prepared both on a GAAP and non-GAAP basis, and the non-GAAP annual financial plan is approved by our board of directors.  Continuous budgeting and forecasting for revenue and expenses are conducted on a non-GAAP basis (in addition to GAAP) and actual results on a non-GAAP basis are assessed against the annual financial plan.  We consider the use of non-GAAP financial measures helpful in assessing the core performance of our continuing operations and when planning and forecasting future periods.  By continuing operations, we mean the ongoing results of the business adjusted for certain expenses and credits, including, but not limited to stock-based compensation, amortization of intangible assets, acquisition-related facilities adjustments, certain litigation costs, acquisition- and integration-related expense, restructuring and related expense, the gain on the settlement of litigation, the reduction in deferred purchase consideration and the tax effect of these adjustments.  Effective for the second quarter of 2019 and for subsequent reporting periods, we no longer adjust for the impact of purchase accounting on revenue and, effective for the first quarter of 2019 and for subsequent reporting periods, we no longer adjust for the impact of the adoption of the new revenue standard in 2018.  While our management uses non-GAAP financial measures as a tool to enhance their understanding of certain aspects of our financial performance, our management does not consider these measures to be a substitute for, or superior to, GAAP measures.  In addition, our presentations of these measures may not be comparable to similarly titled measures used by other companies.  These non-GAAP financial measures should not be considered alternatives for, or in isolation from, the financial information prepared and presented in accordance with GAAP.

Investors are cautioned that there are material limitations associated with the use of non-GAAP financial measures as an analytical tool.  In particular, many of the adjustments to Ribbon’s financial measures reflect the exclusion of items that are recurring and will be reflected in our financial results for the foreseeable future.

Acquisition-Related Revenue and Cost of Revenue; Impact of New Revenue Standard
We provide the historical supplementary non-GAAP financial measure of non-GAAP Total revenue, which, for periods prior to the second quarter of 2019, included revenue related to our acquisitions that we would have recognized but for the purchase accounting treatment of these transactions, and which, for periods prior to the first quarter of 2019, included eliminated revenue resulting from our adoption of the new revenue recognition standard in 2018.  Effective for the second quarter of 2019 and for subsequent reporting periods, we no longer include any increases to non-GAAP revenue arising from the purchase accounting treatment of assumed deferred revenue.  Effective for the first quarter of 2019 and for subsequent reporting periods, we no longer include any increases to non-GAAP revenue arising from the 2018 revenue standard adoption.  Therefore, for the second quarter of 2019 and for subsequent reporting periods, our non-GAAP revenue is equivalent to our GAAP revenue.

Stock-Based Compensation
Stock-based compensation expense is different from other forms of compensation, as it is a non-cash expense.  For example, a cash salary generally has a fixed and unvarying cash cost.  In contrast, the expense associated with an equity-based award is generally unrelated to the amount of cash ultimately received by the employee, and the cost to us is based on a stock-based compensation valuation methodology, subjective assumptions and the variety of award types, all of which may vary over time.  We evaluate performance without these measures because stock-based compensation expense is influenced by the Company’s stock price and other factors such as volatility and interest rates that are beyond our control.  The expense related to stock-based awards is generally not controllable in the short-term and can vary significantly based on the timing, size and nature of awards granted.  As such, we do not include such charges in our operating plans, and we believe that presenting non-GAAP operating results that exclude stock-based compensation provides investors with visibility and insight into our management’s method of analysis and the Company’s core operating performance.  It is reasonable to expect that stock-based compensation will continue in future periods.

Amortization of Intangible Assets
We exclude the amortization of acquired intangible assets from non-GAAP expense and income measures.  These amortization amounts are inconsistent in frequency and amount and are significantly impacted by the timing and size of acquisitions.  Although we exclude amortization of acquired intangible assets from our non-GAAP expenses, we believe that it is important for investors to understand that intangible assets contribute to revenue generation.  We believe that excluding the non-cash amortization of intangible assets facilitates the comparison of our financial results to our historical operating results and to other companies in our industry as if the acquired intangible assets had been developed internally rather than acquired.  Amortization of intangible assets that relate to past acquisitions will recur in future periods until such intangible assets have been fully amortized.

Acquisition-Related Facilities Adjustments
GAAP accounting requires that the deferred rent liability of an acquired company be written off as part of purchase accounting and that the combined company’s rent expense on a straight-line basis begin as of the acquisition date.  As a result, we recorded more rent expense than would have been recognized but for the purchase accounting treatment of GENBAND’s assumed deferred rent liability.  We included this adjustment, which related to the acquisition of GENBAND, through the fourth quarter of 2018, to allow for more complete comparisons to the financial results of our historical operations and the financial results of peer companies.

Litigation Costs
We were involved in litigation with a certain competitor with whom we reached a settlement in the second quarter of 2019, under which the competitor agreed to pay us an aggregate amount of $63.0 million (see also “Litigation Settlement” below).  In connection with this litigation, we have incurred litigation costs beginning in the fourth quarter of 2017.  These costs are included as a component of general and administrative expense.  We believe that such costs are not part of our core business or ongoing operations.  Accordingly, we believe that excluding the litigation costs related to this specific legal matter facilitates the comparison of our financial results to our historical operating results and to other companies in our industry.

Acquisition- and Integration-Related Expense
We consider certain acquisition- and integration-related costs to be unrelated to the organic continuing operations of our acquired businesses and the Company and they are generally not relevant to assessing or estimating the long-term performance of the acquired assets.  In addition, the size, complexity and/or volume of an acquisition, which often drives the magnitude of acquisition- and integration-related costs, may not be indicative of future acquisition- and integration-related costs.  By excluding these acquisition- and integration-related costs from our non-GAAP measures, management is better able to evaluate our ability to utilize our existing assets and estimate the long-term value that acquired assets will generate for us.  We exclude certain acquisition- and integration-related costs to allow more accurate comparisons of our financial results to our historical operations and the financial results of less acquisitive peer companies.  In addition, we believe that providing supplemental non-GAAP measures that exclude these items allows management and investors to consider the ongoing operations of the business both with and without such expenses.

Restructuring and Related Expense
We have recorded restructuring and related expense to streamline operations and reduce operating costs by closing and consolidating certain facilities and reducing our worldwide workforce.  We review our restructuring accruals and facilities requirements regularly and record adjustments to these estimates as required.  We believe that excluding restructuring and related expense facilitates the comparison of our financial results to our historical operating results and to other companies in our industry, as there are no future revenue streams or other benefits associated with these costs.

Gain on Litigation Settlement
We were involved in litigation with a certain competitor with whom we reached a settlement in the second quarter of 2019, under which the competitor agreed to pay us an aggregate amount of $63.0 million (see “Litigation Costs” above).  This gain is included as a component of other income (expense), net.  We believe that such gains are not part of our core business or ongoing operations.  Accordingly, we believe that excluding the gain on litigation settlement related to this specific legal matter facilitates the comparison of our financial results to our historical operating results and to other companies in our industry.

Reduction in Deferred Purchase Consideration
We recorded $8.1 million in other income (expense), net, in the first quarter of 2019 related to the reduction of deferred purchase consideration for Edgewater.  We believe that such reductions to deferred purchase consideration are not part of our core business or ongoing operations, as they relate to specific acquisitive transactions.  Accordingly, we believe that excluding such reductions related to acquisitive transactions facilitates the comparison of our financial results to our historical results and to other companies in our industry.

Tax Effect of Non-GAAP Adjustments
Beginning with the second quarter of 2019 and for subsequent reporting periods, non-GAAP income tax expense is calculated based on an estimated tax rate applied against forecasted annual non-GAAP income.  The non-GAAP income tax expense assumes no available net operating losses or any valuation allowances as a result of reporting significant cumulative non-GAAP income over the past several years.  Due to the methodology applied to our estimated annual tax rate as described above, our estimated tax rate on non-GAAP income will differ from our GAAP tax rate and from our actual tax liabilities.

Adjusted EBITDA
We use Adjusted EBITDA as a supplemental measure to review and assess our performance.  We calculate Adjusted EBITDA by excluding from net income (loss): interest income (expense), net; income tax provision; depreciation; and amortization of intangible assets.  In addition, we exclude from net income (loss):  historical adjustments to revenue and cost of revenue related to revenue reductions resulting from purchase accounting (for periods prior to the second quarter of 2019 only) and adoption of the new revenue standard (for periods prior to the first quarter of 2019 only); stock-based compensation expense; acquisition-related facilities adjustments; certain litigation costs; acquisition- and integration-related expense; restructuring and related expense; and other income (expense), net.  In general, we add back the expenses that we consider to be non-cash and/or not part of our ongoing operations.  Adjusted EBITDA is a non-GAAP financial measure that is used by our investing community for comparative and valuation purposes.  We disclose this metric to support and facilitate our dialogue with research analysts and investors.  Other companies may calculate Adjusted EBITDA differently than we do, limiting its usefulness as a comparative measure.

We believe that providing non-GAAP information to investors, in addition to the GAAP presentation, will allow investors to view the financial results in the way management views them.  We further believe that providing this information helps investors to better understand our core financial and operating performance and evaluate the efficacy of the methodology and information used by our management to evaluate and measure such performance.
