Liquidity workout. Please calculate the current and quick ratios for Singapore Air for 2019. So we have our balance sheet for Singapore Air for 2019, and the first thing we're gonna do is calculate the current ratio. The current ratio is sort of the least conservative of all of the liquidity ratios. It's simply the current assets over the current liabilities, so that would be the 5,499.7 divided by 7,378.4, and that gives us a current ratio of 0.7 times. The quick ratio is more conservative. So for the asset numerator part, we're simply going to look at what's closest to cash. And by that definition, we want to take our cash and bank balances, we want to take our investments, and then we want to take our accounts receivable, unless we know something about accounts receivable that show that would be very difficult to collect on. Everything else we're going to ignore, because there's uncertainty about whether or not they would convert quickly into cash. I'm going to do equals and then I'm gonna take 2,944 and 116.8 and then I'm going to add to that my trade debtors of 1,527.2.

And then I can divide by the total current liabilities of 7,378.4, and I get a quick ratio, which again, should by definition be less than the current ratio of 0.6. Now whether or not these are good or not, we'd have to compare them to some other airlines to see, but the mechanics of the calculations are correct.
