Note(s): Dependent variable is CAR (percentage points). OLS with HC3 robust standard errors in parentheses. Tier 3 is the omitted reference category. Specification (1): tier dummies only. Specification (2): adds RSPO and ISPO dummies and standardised Physical Risk. Specification (3): full controls (log size, book-to-market, leverage, ROA, market beta). All three specifications are estimated on the full sample of 75 firms; missing market-beta observations present in earlier data vintages have since been resolved through the price-based fallback estimation described in the Sample, Data Sources and Variable Construction subsection. Overall model $F$-statistics and cross-sectional-dependence diagnostics for Specification (3) are reported in the Diagnostic Tests and Robustness Checks subsection. *p < 0.10, **p < 0.05, ***p < 0.01
