Please Note: If a firm's stock is not publicly traded, the (Market Value of Equity/Book Value of Debt) ratio cannot be calculated. To correct for this problem, the Z score can be
re-estimated using book values of equity. Altman recommends the following alterations to the ratio weight factors.
Also Note:
The z-score represents a point in time. As such, the z-scores should be
examined over time. Consistently low scores each year are more of a
concern than a one time low score.
KEY:
Z-SCORE ABOVE 2.90--YOU'RE IN GOOD SHAPE
Z-SCORE BETWEEN 2.90 and 1.23--WARNING SIGNS
Z-SCORE BELOW 1.23--BIG TROUBLE--COULD BE HEADING TOWARD BANKRUPTCY
