For financial reporting purposes, Michelotti Co. reported depreciation expense of $12,000 in 2017. In 2018, because of a change in the expected useful life of its equipment, Michelotti reported depreciation expense of $10,000. ( There was no change in the depreciation expense reported on Michelotti's tax return between 2017 and 2018.) What effect did the 2018 change in the method used to compute depreciation expense have on 2018 operating cash flow (compared to what 2018 operating cash flow would have been had the change in the computation not been made).
