Hi Chegg, looking at the consolidated statements of earnings for Nordstrom, Inc., can you please tell what is the non-operating profit before tax (NOPBT), pretax net nonoperating expense, and tax expense. Correct me if I am wrong, but I believe (interest expense, net) is the pretax net nonoperating expense and (income tax expense) is the tax expense. I believe NOPBT includes net sales, credit card revenues, cost of sales and related buying and occupancy costs, but I am not sure if it includes retail and credit. I am not 100% sure if I am right, so please help me for all three. It would help me a lot.
