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
