Bioray Biotech Co  (ROCO:7561) Altman Z2-Score Explanation

The original Z-Score model was based on publicly traded manufacturing companies while the Z2-Score, also known as Z"-score can be used for any type of company excluding property/financial companies. Both Z-Score and Z2-Score describes the financial health of a company, and its likelihood of financial distress.

X1: The Working Capital/Total Assets (WC/TA) ratio is a measure of the net liquid assets of the firm relative to the total capitalization. Working capital is defined as the difference between current assets and current liabilities. Ordinarily, a firm experiencing consistent operating losses will have shrinking current assets in relation to total assets. Altman found this one proved to be the most valuable liquidity ratio comparing with the current ratio and the quick ratio. This is however the least significant of the five factors.

X2: Retained Earnings/Total Assets: the RE/TA ratio measures the leverage of a firm. Retained earnings is the account which reports the total amount of reinvested earnings and/or losses of a firm over its entire life. Those firms with high RE, relative to TA, have financed their assets through retention of profits and have not utilized as much debt.

X3, Earnings Before Interest and Taxes/Total Assets (EBIT/TA): This ratio is a measure of the true productivity of the firm's assets, independent of any tax or leverage factors. Since a firm's ultimate existence is based on the earning power of its assets, this ratio appears to be particularly appropriate for studies dealing with corporate failure. This ratio continually outperforms other profitability measures, including cash flow.

X4_2, Net Worth (Total Stockholders Equity - Preferred Stock)/Total Liabilities (NW/TL): it compares a company’s stock net worth with its total liabilities and can be used to assess the extent of its reliance on debt.
