National Western Life president, Ross Moody, said: "Premium dollars collected during 2012 surpassed $1bn representing the third consecutive year we have accomplished this feat. Since the financial crisis emerged in 2008, we have been able to produce between $2.5bn and $3.0bn of new life insurance coverage each year.
"This is a solid performance given the backdrop of high domestic unemployment and a global financial slowdown we have encountered during this time frame," Moody added.
