Total Non-Controlling Interest is a line reflecting the whole of what was minority interest prior to 2009.
FactSet retained this as minority interest, and this is therefore the correct line to be used with that database.
When using CompuStat, users may prefer NonControlIntRed and NonControlIntNonRed, which are redeemable non-controlling interest, which is is part of liabilities, and non-redeemable non-controlling interest, which is part of shareholders equity. Using either should be fine, but be cautious of double accounting.
