A friend has mentioned that she has read somewhere that the following variables can be used to predict bankruptcy: (a) the company debt ratio; (b) the interest coverage; (c) the amount of cash relative to sales or assets; (d) the return on assets; (e) the market-to-book ratio; (f) the recent return on the stock; (g) the volatility of the stock returns. The problem is that she cant remember whether a high value of each variable implies a high or a low probability of bankruptcy. Can you help her out?
