 combined total of $247.2 million of goodwill as a critical audit matter because of the significant judgments made by management to estimate the fair value of these reporting units. This required a high degree of auditor judgment and an increased extent of effort when performing audit procedures to evaluate the reasonableness of management’s estimates and assumptions related to the revenue growth rate, EBITDA margin and the discount rate. How the Critical Audit Matter Was Addressed in the Audit Our audit procedures related to the revenue growth rate, EBITDA margin, and discount rate used by management to estimate the fair value of the reporting units included the following, among others:

| • |     | We evaluated management’s ability to accurately forecast the revenue growth rate and EBITDA margin by 
 comparing actual results to management’s historical forecasts.                                        |
