NON-GAAP FINANCIAL MEASURES

Non-GAAP Financial Measures

In addition to financial measures presented in accordance with GAAP, we monitor other non-GAAP financial measures that we use 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 that we use in order to maintain and grow our business.

The presentation of these non-GAAP financial measures is used 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.



NON-GAAP FINANCIAL MEASURES



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. • 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. • 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, 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. • 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⁾, 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.


(1)	We have adjusted the non-GAAP effective tax rate to 40.5% for 2017 from 42.5% for 2016, due to a decrease in state income taxes from an increase in excludable income for state income tax purposes. These non-GAAP effective tax rates exclude the income tax impact from stock-based compensation and changes in uncertain tax positions.


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