PEG uses trailing P/E against the 3-year net income growth rate (12.59%/yr) since forward earnings estimates aren't available here, so this is not a "forward PEG." Altman Z-Score below ~1.8 suggests financial distress risk, above ~3.0 suggests low risk; the model is most reliable for industrial/manufacturing companies and less meaningful for banks and other financial firms.
