Thanks, Vic. The clear highlight of fiscal '12, as well as the few weeks subsequent to fiscal yearend is the strength of our orders and the growth of our backlog. During '12, we entered $752 million of new business across the company resulting in a book-to-bill ratio of 109%. Our USG segment led the way with $380 million in orders and $62 million of backlog growth as of September 30. Our largest customer, SoCalGas, awarded Aclara $75 million in orders during fiscal '12 in preparation of their AMI rollout, which began on a small scale in October. Subsequent to fiscal yearend, SoCal awarded an additional $41 million in orders, bringing the contract to-date values to $135 million and over 1.5 million AMI devices and its related software and services.
We reported GAAP EPS of $0.65 in the quarter compared to $0.57 in Q4 of the prior year. While Q4 did not come in where we had originally expected, we are still pleased to see a 14% increase in EPS over prior year. To wrap up the year, I'll provide a few brief overview comments on the segments.
Filtration significantly outperformed expectations on both sales and EBIT throughout the year, and we expect this exceptional performance to continue in '13. EBIT increased 100 basis points to nearly 20%, while sales increased 16% or $27 million with all 4 operating units showing meaningful growth. Test sales were generally consistent with prior year and EBIT was significantly lower, for the reasons we've discussed previously. 2011 also included the most profitable Chamber product in Test history, which furthered the difficult comparisons with 2012. Test performance in '12 resulting from cost overruns has been addressed through improved processes, which will enhance project execution going forward, in addition to several significant cost initiatives being implemented to enhance its operating margin in fiscal '13 and beyond. Our restructuring is moving forward as planned and we expect to have it wrapped up in the second quarter.
Doble continues to perform exceptionally well, as evidenced by their EBIT margin of nearly 23% on increased sales. We continue to invest in the business, and in 2013, we're increasing our sales and marketing efforts to accelerate the sales of our recently introduced new products, software and services.
2012 was a transition year for Aclara, as we came off the 2 large contracts at PG&E in New York City, which had combined revenues of $42 million in 2011. This compares to $9 million in 2012, for a net decrease of $33 million, which is consistent with the net decrease at Aclara in 2012.
The COOP significantly outperformed expectations in fiscal '12, resulting in the best sales year in their history, delivering over $112 million in revenue. The RF Water business was softer than expected, consistent with our earlier communications. On the cash flow and balance sheet front, during 2012, we generated over $53 million in cash from operations and ended the year with a net debt balance of approximately $85 million and leverage at 1.3x at very favorable pricing.
On the buyback front, we repurchased 150,000 shares through September 30, and an additional 270,000 shares in October, bringing the totals to 420,000 shares and $15 million spent. Considering the strength of our current backlog, coupled with the robust pipeline of identified new business opportunities within our AMI product lines, along with SoCal's deployment ramp over the next 12 months, 2013 sales and EPS growth is expected to be significant when compared to 2012.
I'll be happy to address any specific financial questions during the Q&A. And now I'll turn it back over to Vic.
