Effective December 20, 2018, the Company acquired Oasis. Upon closing, Oasis became a wholly owned subsidiary of the Company. Oasis is an industry leader in providing HR outsourcing services.

The results of operations for Oasis have been included in the Company’s Consolidated Statements of Income and Comprehensive Income since the date of acquisition. During fiscal 2019, Oasis contributed $163.7 million of total revenues and $5.1 million of operating income, including the impact of certain one-time charges related to the acquisition and integration of the Oasis business, in the Company’s consolidated results of operations.

Pro Forma Financial Results (Unaudited): The following table summarizes the Company’s unaudited pro forma operating results for fiscal 2019 as if the acquisition of Oasis had been consummated as of June 1, 2017. The following pro forma information does not include the impact of any costs incurred to integrate Oasis’ operations:

The unaudited pro forma operating results have been calculated after applying the Company’s accounting policies and include the acquisition of Oasis adjusted, net of tax, for depreciation and amortization expense resulting from the determination of fair values of the acquired property and equipment and amortizable intangible assets, the inclusion of interest expense related to borrowings used to fund the acquisition, the amortization of debt issuance costs related to the permanent financing of debt, the elimination of interest income related to available cash used for the acquisition, and the elimination of Oasis’ interest expense related to debt not assumed in the acquisition. Since the pro forma financial results assume the acquisition was consummated on June 1, 2017, the unaudited pro forma operating results for fiscal 2019 excluded $2.7 million ($2.0 million, net of tax) of costs incurred by the Company related to the acquisition of Oasis.

The pro forma financial information does not purport to be indicative of the results that would have been obtained had the transactions been completed as of June 1, 2017 for the period presented and are not intended to be a projection of future results or trends.
