A higher ratio indicates a larger probability of bankruptcy for the company, while a lower ratio indicates a healthier fundamental.

Like the Altman Z-Score, the PFD measures a company's bankruptcy risk. However, the main drawback of the Z-score is it does not apply to banks and insurance companies. According to Investopedia, the concept of "working capital" does not apply to banks and insurance companies, as financial institutions do not have typical current assets or current liabilities like inventories or accounts payable.

1.60 * TLMTA
-
7.88 * EXRETAVG
+
