Although, IFRS has a lot of advantages over the GAAP, a lot of people believe that US GAAP is better than IFRS. IFRS has its own disadvantages in front of GAAP. The US organizations which do not have enough operations outside the US do not have enough incentive to prepare financial records as per the IFRS. Also, there are some filings with some authorities that require GAAP. Thus, for US organizations that need these filings, it results in additional costs to follow both GAAP and IFRS.  Moreover, IFRS is known to provide much lesser detail than the GAAP.  Christopher Nobes (1997).
