Working capital

Dear Moffat, Hope you are fine. Thank you for your nice lectures. I just have a short question regarding the items of working capital. As far as I know working capital is current asset less current liabilities. My question is which items should be taken into consideration for current assets and current liabilities? These are only Cash + TRADE receivable + Inventory - TRADE payable ? I mean other receivable, other payable, prepayments, short-term provisions, bank overdraft etc are not considered as working capital. Yes? Thanks you in advance
