  1. The index volatility (risk) is measured by variable (h m,t ), INT t − 1 is short term interest rate volatility, FX t − 1 is foreign exchange volatility, and α 0, α 1, β, δ 1and δ 2 are parameters
  2. Note: Numbers in parentheses are t-values * Significant at 1 % level; ** Significant at 5 % level; *** Significant at 10 % level
