SELECTED FINANCIAL DATA

Non-GAAP Financial Measures

In addition to the selected financial measures presented in accordance with U.S. Generally Accepted Accounting Principles (GAAP), we monitor other non-GAAP financial measures to manage our business, make planning decisions, allocate resources and as performance measures in our executive compensation plan. These key financial measures provide an additional view of our operational performance over the long term and provide useful information regarding how cash is generated and utilized in order to maintain and grow our business.

These financial measures also provide useful information by eliminating the effect of certain non-cash items that can fluctuate significantly from period to period, as well as certain significant items that are not representative of our business operations such as our initial public offering (IPO) transaction costs. They enhance investors’ ability to review our business from the same perspective as the management and facilitate consistent period to period comparisons by excluding items that we do not believe are indicative of our operating performance.

The presentation of the non-GAAP financial measures is to enhance the understanding of certain aspects of our financial performance. It is not meant to be considered in isolation, superior to, or as a substitute for the directly comparable financial measures prepared in accordance with GAAP.



SELECTED FINANCIAL DATA



Non-GAAP Measure	Definition	How We Use The Measure
Net Service Revenues	• Sum of professional service revenues and Net Insurance Service Revenues, or total revenues less insurance costs.	• Provides a comparable basis of revenues on a net basis. Professional service revenues are represented net of client payroll costs whereas insurance service revenues are presented gross of insurance costs for financial reporting purposes. • Acts as the basis to allocate resources to different functions and evaluates the effectiveness of our business strategies by each business function, and • Provides a measure, among others, used in the determination of incentive compensation for management.
Net Insurance Service Revenues	• Insurance revenues less insurance costs.	• Is a component of Net Service Revenues, and • Provides a comparable basis of revenues on a net basis. Professional service revenues are represented net of client payroll costs whereas insurance service revenues are presented gross of insurance costs for financial reporting purposes. Promotes an understanding of our insurance services business by evaluating insurance service revenues net of our WSE related costs which are substantially pass-through for the benefit of our WSEs. Under GAAP, insurance service revenues and costs are recorded gross as we have latitude in establishing the price, service and supplier specifications.
Adjusted EBITDA	• Net income, excluding the effects of: - income tax provision, - interest expense, - depreciation, - amortization of intangible assets, and - stock-based compensation expense	• Provides period-to-period comparisons on a consistent basis and an understanding as to how our management evaluates the effectiveness of our business strategies by excluding certain non-cash charges such as depreciation and amortization that have fluctuated significantly over the past five years, and stock-based compensation recognized based on the estimated fair values. We believe these charges are not directly resulting from our core operations or indicative of our ongoing operations. • Enhances comparisons to prior periods and, accordingly, facilitates the development of future projections and earnings growth prospects, and • Provides a measure, among others, used in the determination of incentive compensation for management.
Adjusted Net Income	• Net income, excluding the effects of: - effective income tax rate⁽¹⁾, - stock-based compensation, - amortization of intangible assets, - non-cash interest expense⁽²⁾, - debt prepayment premium, and - the income tax effect (at our effective tax rate⁽¹⁾) of these pre-tax adjustments.	• Provides information to our stockholders and board of directors to understand how our management evaluates our business, to monitor and evaluate our operating results, and analyze profitability of our ongoing operations and trends on a consistent basis by excluding certain non-cash charges as described above, debt payment premiums and our secondary offering costs as these are not directly resulting from our core operations or indicative of our ongoing operations.

(1)

For purposes of our non-GAAP financial presentation, as a result of a 2015 increase in New York City tax rates and an increase in blended state rates, we have adjusted the effective tax rate to 42.5% for 2016, from 41.5% for 2015. Each of these effective tax rates exclude income tax on non-deductible stock-based compensation and discrete items including the cumulative effect of state legislative changes.

(2) Non-cash interest expense represents amortization and write-off of our debt issuance costs.
