Using the latest edition of the Model Business Corporation Act's introduction, I prepared this map, in which red states have adopted all or substantially all of the current edition of the MBCA. Two states plus the District of Columbia have acts based on the 1969 MBCA. (Note that many of the white states have adopted selected provisions of the MBCA, albeit often with modifications.) BTW, I wonder if there is anything to be said about the fact that the MBCA dominates in the Southeast and Northwest, plus New England. Probably not, but ....
