18. UNAUDITED SELECTED QUARTERLY DATA

Unaudited quarterly financial results are set forth in the following tables. It is the company’s long-standing practice to establish actual interim closing dates using a “fiscal” calendar, which requires the businesses to close their books on a Friday, in order to normalize the potentially disruptive effects of quarterly close on business processes. The effects of this practice only exist within a reporting year.
