I am looking at Carnival corp. balance sheet and I see that they have $1.586B in current assets and $6.763B in current liabilities. How is that possible? They current assets should be greater than the current liabilities, or not? How can they pay their accounts payable? Why aren't they bankrupt?
Here it's their balance sheet:
