Additional report context:
1 . the aggregate amounts include losses of approximately $ 1.29 billion and $ 324 million reported in 201cmarket making 201d and 201cother principal transactions , 201d respectively . the net unrealized loss on level 3 derivatives of $ 1.37 billion for 2013 principally resulted from changes in level 2 inputs and was primarily attributable to losses on certain credit derivatives , principally due to the impact of tighter credit spreads , and losses on certain currency derivatives , primarily due to changes in foreign exchange rates . transfers into level 3 derivatives during 2013 primarily reflected transfers of credit derivative assets from level 2 , principally due to reduced transparency of upfront credit points and correlation inputs used to value these derivatives . transfers out of level 3 derivatives during 2013 primarily reflected transfers of certain credit derivatives to level 2 , principally due to unobservable credit spread and correlation inputs no longer being significant to the valuation of these derivatives and unobservable inputs not being significant to the net risk of certain portfolios . goldman sachs 2013 annual report 143 .

Question: what was the difference in millions in the aggregate amount of losses reported in 201cmarket making 201d and 201cother principal transactions 201d respectively?
