Adjusted expense reconciliation 1Includes general and operating expenses and professional fees. Note: Percentage variance based on actual numbers, not rounded results.

Adjusted net income walk Note: Asterisk denotes line item numbers post adjustment; numbers are rounded, and totals may not sum.

Revenue less cost of revenue reconciliation

Adjusted EBITDA reconciliation “Share-based compensation” represents granted share-based compensation in the form of RSA, restricted stock unit, stock option, and stock appreciation right grants by us to certain of our directors and employees. Although this expense occurred in each measurement period, we have added the expense back in our calculation of adjusted EBITDA because of its noncash impact. “Reorganization and integration costs” includes costs related our functional reorganization within our Operations, Technology and Retirement functions as well as duplicate costs related to the outsourcing of back-office operations functions. While we have incurred such expenses in all periods measured, these expenses serve varied reorganization and integration initiatives, each of which is non-recurring. We do not consider these expenses to be part of our core operations. “Acquisition expenses” includes employee severance, transition and retention expenses, duplicative general and administrative expenses and other professional fees related to acquisitions. “Business continuity plan” includes incremental compensation and other costs that are directly related to a transition to a primarily remote workforce in 2021 and a transition to a hybrid workforce in 2022, and other costs due to the COVID-19 pandemic. “Office closures” represents one-time expenses related to closing facilities.

Adjusted Net Income reconciliation (1) Relates to intangible assets established in connection with HTSC’s acquisition of our Company in 2016. (2) Consists of the adjustments to EBITDA listed in the adjusted EBITDA reconciliation table above other than share-based compensation. (3) Consists of the provision for income taxes under U.S. GAAP and the estimated tax impact of expense adjustments and acquisition-related amortization, and share-based compensation beginning in 2022.
