resulting from growth in our new software licenses revenues and our software license updates and product support revenues. These increases were partially offset by a constant currency decrease in our total services revenues that we believe was caused by weaker demand for IT services due to the deterioration in global economic conditions in recent periods. Excluding the effect of currency rate fluctuations, the Americas contributed 55%, EMEA contributed 32% and APAC contributed 13% to our total revenues growth.

Excluding the unfavorable effect of currency rate fluctuations, the increase in total operating expenses in fiscal 2010 was due to additional operating expenses incurred as a result of our acquisition of Sun, including increased expenses pertaining to hardware systems products sold and related hardware systems support offerings, additional employee related expenses including additional stock-based compensation, and an increase in intangible asset amortization. In addition, we also incurred increased restructuring expenses resulting from our Sun Restructuring Plan and legacy Oracle-based restructuring plans. These increases were partially offset by expense reductions in our legacy Oracle-based operations including expense reductions in our services business, reductions in bad debt expenses due to improved collections and reductions to travel expenses due to cost management initiatives.

On a constant currency basis, our operating margin increased during fiscal 2010 due to higher revenues from our software business, partially offset by an estimated $620 million reduction to our operating income from Sun. Our operating margin as a percentage of revenues declined in fiscal 2010 due to the post-combination expense contributions from our new hardware systems business and due to our acquisition related expenses, restructuring expenses and amortization of intangible assets, which increased at a faster rate than our total revenues, primarily due to Sun.

Fiscal 2009 Compared to Fiscal 2008:      Our operating results for fiscal 2009 were unfavorably impacted by the strengthening of the U.S. Dollar relative to other major international currencies. These currency variances resulted in a reduction to our total revenues growth of 6 percentage points during fiscal 2009. On a constant currency basis, total revenues increased in fiscal 2009 primarily due to higher software license update and product support revenues in all regions and incremental revenues from our recent acquisitions, primarily our acquisition of BEA. On a constant currency basis, new software license revenues contributed 5% to the growth in total revenues, software license updates and product support revenues contributed 92% and services revenues contributed 3%. Excluding the effect of currency rate fluctuations, the Americas contributed 39% to the increase in total revenues, EMEA contributed 42% and Asia Pacific contributed 19%.

Favorable currency variances resulted in a reduction to our total operating expense growth of 5 percentage points during fiscal 2009. Excluding the effect of currency rate fluctuations, the increase in operating expenses in fiscal 2009 is primarily due to
