Note that this table displays Christoffersen’s independence test [8] for the weights of domestic assets of 0.5. The data samples are split into two parts. The 1-day VaRs are estimated from January 1, 2004 to July 31, 2007 (Period I). The second part is used to forecast VaRs from August 1, 2007 to November 27, 2009 (Period II). 𝐼 𝑡 = 0 represents an indicator function if VaR is not exceeded at time 𝑡 ; otherwise; 𝐼 𝑡 = 1 if VaR is exceeded at time 𝑡 . The critical value is 3.84 at a significant level of 5 percent.
