Does it mean 'over $200 mln.', 'more than $200 mln.'?
Yes, exactly.

Also note such expressions as "his finances / health / school-marks went south", meaning "into decline, downward, got worse".

(Actually, I would say that using "south" to figuratively mean "down" or "under" is probably more commonly heard than using "north" to mean "up" or "over".)
