Recent Accounting Pronouncements

In July 2012, the Financial Accounting Standards Board ("FASB") issued an amendment to accounting rules related to the testing of indefinite-lived intangibles.  The new accounting rules permit an entity to first assess qualitative factors to determine if it is more likely than not that an indefinite-lived asset is impaired as a basis for determining whether it is necessary to perform the quantitative impairment test prescribed under current accounting rules.   Roper adopted this guidance on January 1, 2013.  The guidance did not have an impact on the Company's results of operations, financial position or cash flows.
