For the three months and year ended December 31, 2012, we reported consolidated revenue of $2.7 billion and $10.3 billion, reflecting year-over-year growth rates of 14% and 8%, respectively, compared to the prior year. The performance in both periods resulted primarily from the positive contribution of acquisitions, principally Kabel BW, as well as our record organic RGU growth. When adjusting for the impact of acquisitions and FX, we achieved year-over-year rebased revenue growth of 7% and 6% for the three-month and full-year 2012 periods, respectively. These results compare to 5% rebased growth that we reported last year for both the fourth quarter and full-year 2011 periods.
Our fourth quarter rebased revenue growth reflects our strongest quarterly performance of 2012 and our fastest growth quarter in five years, driven by triple-play and mobile subscriber growth. Of particular note, our best performing operations were Germany and Belgium, which delivered rebased revenue growth of 13% and 9%, respectively. Turning to our annual results and similar to the fourth quarter, our rebased revenue growth of 6% was our best top-line performance in five years. Our western European operations generated 7% year-over-year rebased growth, led by Germany and Belgium with 11% and 8%, respectively.
Operating Cash FlowOCF increased 14% to $1.3 billion and 9% to $4.9 billion for the three months and year ended December 31, 2012, respectively, compared to the corresponding prior year periods. Similar to our top-line performance, our reported OCF growth reflects the positive impacts of acquisitions as well as organic growth, partially offset by the negative impact of foreign currency movements. Adjusting for FX and acquisitions, we achieved rebased OCF growth of 6% and 4% for the quarter and year ended December 31, 2012, respectively. Our Q4 rebased OCF growth was aided somewhat by the aggregate impact of certain non-recurring items included in our Belgium results.
