North America segment revenue grew 9% for the Second Quarter, with US growth of 12% over the prior year. On a normalized basis, organic US revenue growth was 5% which was comprised of growth in our direct channels of 12% and growth in our ISO channel of less than 1% during the quarter. As anticipated, growth in our ISO business continues to decelerate and this channel is becoming an increasingly smaller portion of our business. Our ISOs now contribute approximately 15% of our North America operating income, and approximately 8% of total company operating income, which compares to approximately 20% and low double digits respectively as of Q3 of Fiscal 2014. Despite local currency performance of 6% revenue growth, Canada revenue growth in US dollars declined 2%, resulting from an unfavorable exchange rate.
North America cash operating income grew 10% to $85.4 million, and cash operating margins were 17.5%, up from last year, driven by growth in our direct channel, partially offset by unfavorable Canadian FX trend on a year-over-year basis. International revenue grew 11% for the quarter in US dollars. Europe delivered strong revenue growth of 9%, fueled by performance in Spain and E-Commerce channel, offset by continued under performance in our Russia business in light of the general economic environment and ruble devaluation. As a result of strength in the rest of our business, Russia now represents approximately 2% of total company revenues, down from approximately 3% last quarter.
Asia Pacific revenue grew 21%, driven by strong organic revenue growth and the Ezidebit acquisition, which contributed approximately 12 percentage points to the growth rate. Our organic growth in the region was primarily a result of a combination of increased volumes, growth in dynamic currency conversion, and selective pricing initiatives. International cash operating income grew 20% to $83.5 million and cash operating margins increased to 40.1%. Our effective tax rate for the quarter on a cash basis was 26.7%. We generated approximately $105 million of free cash flow this quarter, which we define as net operating cash flows, excluding the impact of settlement assets and obligations, less capital expenditures and distributions to non-controlling interests.
Capital expenditures totaled $15 million for the quarter and our total available cash including working capital at the end of the quarter was approximately $225 million. Lastly, we repurchased a total of approximately 700,000 shares during the quarter for approximately $47 million. Now I’d like to turn to our expectations for Fiscal 2015. Based on our results for the first half of Fiscal 2015, we are increasing our outlook for the full fiscal year. We now expect reported revenue to grow 8% to 10%, and range from $2.75 billion to $2.8 billion. Similarly, we are raising our cash earnings per share expectations to a range of $4.75 to $4.83 reflecting growth of 15% to 17%. We also now expect core cash operating margins to expand by as much as 50 basis points in Fiscal 2015, with margin expansion in both our North America and international segments. It is important to note that these expectations also reflect further strengthening of the US dollar against most of the foreign currencies to which we have exposure which represents a more meaningful headwind to our financial results for the remainder of the year.
