By the implematation of IFRS In Indonesia 2012, there is an increasing in huge number of acquisition by foreign company in Indonesia. The acquisition of those foreign company will be a very interesting topic to discuss because it will bring a big deal with many good impacts to Indonesia it self, by literature study we try to analyze about the case of 7 foreign insurance company which came suddenly to invested their money in Indonesia by 2010. From our research, we find conclusion that those foreign companies were attracted to do acquisition because Indonesia did not still apply IFRS that the acquisition were cheap because the rule of IFRS to value by fair value all the asset were not still applied, while in 2012, IFRS will be used that those foreign companies wil not have problem because the accounting standart between parent andsubsidiary company will be the same. Government support the acquisition by foreign companies and implementation of IFRS because it can develop business in Indonesia and maximaze tax as IFRS prohibit the use of pooling of interest method
