Hi ! I'm doing a Financial analysis of a company and between two years relative some operating expenses it is observed:

Year 2013 2012

Acquisiton related and other $604m ($56m)

So in 2013 compared to 2012 the Acquisiton related and other contributes to reduce a lot the amount of total operating expenses (-1179% regarding the amount of 2012), please what could be the possible interpretation/insights for this important change of Acquisition related and other ?

Waiting inputs/insights

Thanks
