Review GARCH model basics

Given the GARCH(1,1) model equation as:

Formula

Intuitively, GARCH variance forecast can be interpreted as a weighted average of three different variance forecasts. One is a constant variance that corresponds to the long run average. The second is the new information that was not available when the previous forecast was made. The third is the forecast that was made in the previous period. The weights on these three forecasts determine how fast the variance changes with new information and how fast it reverts to its long run mean.

Which of the following statements is incorrect?
