During the fourth quarter ended August 31, 2019, the Company changed its accounting principle related to the presentation of third party delivery costs associated with shipping and handling activities previously included as operating expenses in Distribution in the Consolidated Statements of Operations and Comprehensive Income. The Company now presents these expenses within Cost of goods sold in the Consolidated Statements of Operations and Comprehensive Income. In connection with the change in accounting principle, the Company also changed its definition of shipping and handling costs to include costs paid to third-party warehouse operators associated with delivering product to a customer, previously included in General and administrative, and Depreciation and amortization of the assets at the third-party warehouse, previously included in Depreciation and amortization. Under the previous definition of shipping and handling costs, the Company only included delivery costs in Distribution. The effect of the adjustment is as follows:
