Operating expenses were favorably affected by 1 percentage point as a result of the strengthening of the United States dollar relative to other major international currencies. Excluding the effect of currency rate fluctuations, the increase in operating expenses is primarily due to higher headcount levels and associated personnel related costs in sales and marketing, consulting and research and development, higher commissions due to the increase in revenues and greater amortization of intangible assets, offset partially by lower restructuring and acquisition related expenses. Operating margins as a percentage of total revenues decreased slightly due to higher costs associated with acquisitions, principally amortization of intangible assets.
