In prior periods, our calculation was based on invoice data. We’ve made this change to simplify the calculation and more easily integrate acquired operations into our financial metrics. The prior year metrics have been restated for the new method which reduced days payables and increased cash cycle by a range of 7 to 9 days from previously reported cash cycle figures.
