4.3Bankruptcy and financial distress analysis Discriminant Model (Y is the value of z-score) (4.5) TABLE 4.2 Mean ratios of bankrupt / nonbankrupt firms From Altman, E. I., “Financial ratios, discriminant Analysis, and the prediction of corporate bankruptcy,” Journal of Finance 23 (1968), p. 596, Table I. Reprinted by Permission of Edward I. Altman and Journal of Finance. Z-score >2.99 : non-bankrupt sector; Z-score < 1.81 : bankruptcy; Z-score between 1.81 and 2.99 : gray area. Ratio Definition Bankrupt Group Mean Nonbankrupt Group Mean X1X1 Working capital / total assets X2X2 Retained earnings / total assets X3X3 EBIT/ total assets X4X4 Market value of equity / book value of total debt X5X5 Sales / total assets

Empirical When we apply Equation (4.5) to calculate financial Z- score, the model should be defined as Here we use JNJ in 2005 as an example, Then, the z-score for JNJ is 1.2(0.3233)+1.4(0.7147)+3.3(0.2353)+0.6(8.8683)+1.0( ) = Ratio Definition JNJ X1X1 Net Working capital / total assets ( current asset –current liability ) / total assets X2X2 Retained earnings / total assets X3X3 EBIT/ total assets X4X4 Market value of equity / book value of total debt X5X5 Sales / total assets

4.3Bankruptcy and financial distress analysis ClassSize of SampleDefinition 1. PPO2(1.8%) Serious problem-potential payoff. An advanced problem bank that has at least 50 percent chance of requiring financial assistance in the near future. 2. SP14(12.7%) Serious problem. A bank whose financial condition threatens ultimately to obligate financial outlay by the FEIC unless drastic changes occur. 3. OP94(85.5%) Other problem. A bank with some significant weakness, with vulnerability less than class 2, but still calling for aggressive supervision and extraordinary concern by the FEIC.

4.6Bond quality ratings and the change of quality ratings for the electric utility industry The multivariate-analysis technique developed by Pinches and Mingo for analyzing industrial bond ratings has also been used to determine bond quality ratings and their associated changes for electric utilities. Pinches, Singleton, and Jahakhani (1978) (PSJ) used this technique to determine whether fixed coverages were a major determinant of electric utility bond ratings. Bhandari, Soldofsky, and Boe (1979) (BSB) investigate whether or not a multivariate discriminant model that incorporates the recent levels, past levels, and the instability of financial ratios can explain and predict the quality rating changes of electric utility bonds. PSJ (1978) found that fixed coverage is the only (and not the dominant) financial variable that apparently influences the bond ratings assigned to electric utility firms. Other important variables are the climate of regulation, total assets, return on total assets, growth rate or net earnings, and construction expenses/total assets.2 The major finding of BSB’s study is that the MDA method can be more successful in predicting bond rating changes than it had been predicting the bond ratings themselves. These results have shed some light for the utility regulation agency on the determinants of bond ratings and the change of bond ratings for electric utility industries. 31

4.7Ohlson’s and Shumway’s methods for Estimating Default Probability X 1 = Natural log of (Total Assets/ GNP Implicit Price Deflator Index). The index assumes a base value of 100 for 1968; X 2 = (Total Liabilities/Total Assets); X 3 = (Current Assets – Current Liabilities)/Total Assets; X 4 = Current Assets/ Current Liabilities; X 5 = One if total liabilities exceeds total assets, zero otherwise; X 6 = Net income/total assets; X 7 = Funds provided by operations/total liabilities; X 8 = One if net income was negative for the last two years, zero otherwise; and X 9 = (Net income in year t – Net income in t–1) / (Absolute net income in year t + Absolute net income in year t–1). 32

34
4.7Ohlson’s and Shumway’s methods for Estimating Default Probability (4.9) Where, P = the probability of bankruptcy; X 1 = Net Income/Total Assets; X 2 = (Total Liabilities/Total Assets); X 3 = The logarithm of (each firm’s market capitalization at the end of year prior to the observation year / total market capitalization of NYSE and AMEX market); X 4 = Past excess return as the return of the firm in year t-1 minus the value-weighted CRSP NYSE/AMEX index return in year t - 1; and X 5 = idiosyncratic standard deviation of each firm’s stock returns. It is defined as the standard deviation of the residual of a regression which regresses each stock’s monthly returns in year t – 1 on the value-weighted NYSE/AMEX index return for the same year. 34

4.8Summary In this chapter, we have discussed applications of two multivariate statistical methods in discriminant analysis and factor analysis. Examples of using two-group discriminant functions to perform credit analysis, predict corporate bankruptcy, and determine problem banks and distressed P-L insurers were discussed in detail. Basic concepts of factor analysis were presented, showing their application in determining useful financial ratios. In addition, the combination of factor analysis and discriminant analysis to analyze industrial bond ratings was discussed. Finally, Ohlson’s and Shumway’s methods for estimating default probability were discussed. In sum, this chapter shows that multivariate statistical methods can be used to do practical financial analysis for both managers and researchers. 35
