An acid-test ratio between and 1.0 is usually considered satisfactory but could also be a sign of some cash flow problems.

The acid-test ratio, also known as the quick ratio, is a measure of a company's ability to meet its short-term obligations using its most liquid assets. It is calculated as follows:

Acid-Test Ratio = (Cash + Marketable Securities + Accounts Receivable) / Current Liabilities

A ratio between 1.0 and 1.0 is generally considered satisfactory as it indicates that the company has enough liquid assets to cover its current liabilities. However, it could also be a sign of potential cash flow problems. This is because a ratio of 1.0 means that the company has just enough liquid assets to cover its current liabilities, but not more. If the company's cash flow is not managed properly, it could run into problems meeting its obligations.

For example, if a company has a large amount of accounts receivable that are not being collected quickly enough, it could struggle to pay its bills even though its acid-test ratio is satisfactory. Similarly, if the company has a large amount of cash tied up in marketable securities that it cannot sell quickly, it could also run into cash flow problems.

Therefore, while a satisfactory acid-test ratio is a good sign, it is also important to look at other indicators of a company's financial health, such as its cash conversion cycle, to get a complete picture of its financial situation.
