Probably just to take advantage of the same things most companies do:
"The State of Delaware is a leading domicile for U.S. and international corporations. More than 1,000,000 business entities have made Delaware their legal home. More than 50% of all publicly-traded companies in the United States including 64% of the Fortune 500 have chosen Delaware as their legal home."
Wonder if Robert Moody is getting ready to step down in general. If so, maybe some of the discussion we've had here about being more shareholder friendly may come through for NWLI.
I still think of NWLI in a simlar vein to EVT.TO, where EVT.TO was a long term insurance and holding company with a minimal dividend, but when daddy stepped down, junion increased dividends and sold half the company to increase value.
