Our remarks today will include forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995. We will make forward-looking statements about, among other matters, adjusted revenue, adjusted internal revenue growth, adjusted earnings per share, adjusted operating margin, free cash flow, free cash flow per share, sales pipelines, acquisitions and our strategic initiatives. Forward-looking statements may differ materially from actual results and are subject to a number of risks and uncertainties. Please refer to our earnings release, which can be found on our website at fiserv.com, for a discussion of these risk factors.
You should also refer to our earnings release for an explanation of the non-GAAP financial measures discussed in this conference call, and for a reconciliation of those measures to the nearest applicable GAAP measures. These non-GAAP measures are indicators that management uses to provide additional meaningful comparisons between current results and prior-reported results, and as a basis for planning and forecasting for future periods.
I will now turn the call over to Jeff.
Jeffery YabukiThanks, Peter, and good afternoon. On the heels of our strong finish to 2011, we delivered revenue growth and adjusted EPS that exceeded our internal expectations for the quarter. We are pleased with our start to the year and are well-positioned to achieve results within our full-year guidance. Adjusted revenue increased 5% in the quarter and adjusted internal revenue growth was 4%, including solid results in both our Payments and Financial segments. Adjusted earnings per share was up 18% for the quarter to $1.20, and adjusted operating margin expanded 40 basis points over the first quarter of 2011. Free cash flow was $183 million in the quarter, below the outstanding results in the comparative quarter, primarily related to relative changes in working capital. Cash flow remains on track for the year. In February, we reinforced our commitment to building shareholder value through an additional repurchase authorization for 10 million shares. To that end, we also repurchased 3.7 million shares in the quarter.
