notes to consolidated financial statements level 3 rollforward if a derivative was transferred to level 3 during a reporting period , its entire gain or loss for the period is included in level 3 . transfers between levels are reported at the beginning of the reporting period in which they occur . in the tables below , negative amounts for transfers into level 3 and positive amounts for transfers out of level 3 represent net transfers of derivative liabilities . gains and losses on level 3 derivatives should be considered in the context of the following : 2030 a derivative with level 1 and/or level 2 inputs is classified in level 3 in its entirety if it has at least one significant level 3 input . 2030 if there is one significant level 3 input , the entire gain or loss from adjusting only observable inputs ( i.e. , level 1 and level 2 inputs ) is classified as level 3 . 2030 gains or losses that have been reported in level 3 resulting from changes in level 1 or level 2 inputs are frequently offset by gains or losses attributable to level 1 or level 2 derivatives and/or level 1 , level 2 and level 3 cash instruments . as a result , gains/ ( losses ) included in the level 3 rollforward below do not necessarily represent the overall impact on the firm 2019s results of operations , liquidity or capital resources . the tables below present changes in fair value for all derivatives categorized as level 3 as of the end of the year. .

Question: what was the difference in millions in the aggregate amount of losses reported in 201cmarket making 201d and 201cother principal transactions 201d respectively?
Answer: 966
Calculation: subtract(multiply(1.29, const_1000), 324)
