Thank you, Rohit. And good morning, everyone. In the fourth quarter, EXL reported of $104.6 million, up 43% year-over-year and 2% sequentially, meeting our expectations. Year-over-year revenue growth was driven both by acquisitions as well as strong revenue increases from new and existing clients. Our sourcing segment reported revenue of $89.7 million, up 58% year-over-year and 5% sequentially. The sequential growth was driven by growth from existing clients in insurance, including an impressive initial quarter of platform BPO revenue from a global retirement services provider.
Transformation reported revenues of $14.9 million in the first quarter, down year-over-year and sequentially. Start dates for our 2 new project wins were pushed back into the next quarter affecting our top line. While our new deal revenue represents approximately 1/3 of our transformation business, approximately 2/3 is short-term projected business revenue, which is more volatile and difficult to predict quarter-on-quarter. As Rohit outlined, we are encouraged by a strong recent client win and the pipeline for rest of the year in this business. I remain optimistic about the transformation showing solid revenue growth for this year.
In the first quarter, our gross margin was 36.3%, down approximately 300 basis points sequentially, driven by 3 drivers. First, 150 basis points from low utilization and advanced hiring in our transformation business and new capacity added in the Philippines. Second, 80 basis points from foreign exchange headwinds from -- an appreciating rupee, which was 51.4 in Q4 of '11, versus an average of 49.8 in Q1 of 2012. Third, 70 basis points from investments in our BPO platform business. We addressed the gross margin challenge early. As the quarter went on, we saw a pickup in our transformation revenues coupled with better utilization. With the utilization and transformation in coming quarters along with our ramp-ups in our Manila and SEZ facilities and tighter operating cost control, we expect to improve the gross margins in the second half of the year, except in Q2, where we will absorb the impact of employee compensation increments.
In the fourth quarter, G&A cost as a percentage of revenue was 12.8%, down 160 basis points year-over-year and 140 basis points quarter-on-quarter while the sales and marketing as a percent of revenue was at 7.5%, which was down 60 basis points year-over-year and 100 basis points, sequentially. This improvement in SG&A margins of approximately 220 basis points year-over-year helped us to offset our decline in gross margins thereby maintaining our operating margins year-over-year.
In the fourth quarter, DSO of 50 days improved from the 56 days in the prior quarter or a year ago quarter driven by improvements in collections management. This resulted in a strong balance sheet with approximately $90 million of cash and equivalents as of March 31, 2012, even after we paid out the bonuses in first quarter and no debt outstanding.
In the first quarter, our tax rate was 25.3%. Stable quarter-on-quarter, but up from 11.8% a year ago driven by primarily by onetime release of our valuation allowance related to expiring of our tax holiday in India in Q1 of last year. In 2012, we continue to expect our tax rate would be in the mid-20%s as we expand in SEZ facilities in India and set up facilities in the Philippines.
First quarter net income was $8.9 million versus $8.4 million in a year-ago quarter despite our EDR [ph] increasing from 11.8% to 25.3%. Diluted earnings per share was $0.27, even with the year-ago quarter. And adjusted earnings per share was $0.36. It was at $0.33 a year ago.
Now turning to 2012 guidance. As Rohit mentioned, and as was highlighted by us previously, approximately 25% of our client portfolio we passed the foreign exchange risk to our clients, which in turn subject our revenue forecast to the volatility of the dollar-rupee exchange rate. The dollar-rupee exchange rate has moved significantly by about 8% versus our last guidance. This negatively impacted our revenue forecast for the year to the tune of approximately $6 million, if our current rates of 53 rupees to the dollar were to persist for the balance of the year.
Recently, we have seen some delays in decision-making on larger outsourcing projects, which were -- we were anticipating closing in the near term. Long sales cycles are a natural part of the BPO business and these long sales cycles once finished, drive multi-year high-visible revenue contracts. These long cycles have also highlight how critical the process we manage for clients are. We continue to see a robust pipeline for new business and I am enthusiastic that we are making the right investment to win these decisions when they occur.
Taking these 2 factors together, we are guiding to the bottom of our 2012 revenue guidance to $445 million to $445 (sic) [$455] million, representing a 24% growth year-over-year excluding onetime client payment in 2011, which translates to an organic growth rate of about 13% growth of the 16% organic growth on a constant currency basis. This guidance assumes that rupee stays at current rates of 53 rupees to the dollar for the balance of the year.
At this exchange rate, we expect foreign exchange losses for the year to be approximately between $3.5 million to $4 million, pretax. With the depreciating Indian rupee negatively impacts our revenue forecast, our effective foreign exchange hedging program will continue to protect our bottom line. As such, we are reiterating our 2012 adjusted earnings per share guidance of $1.50 to $1.55. Should the rupee change, or if there is a change in the pace of decision making on the part of our clients, we will adjust our revenue guidance accordingly. However, we are not anticipating a change in our EPS guidance as mentioned above.
We remain energized to seize the opportunity of growth ahead of us. Recent contracts will tell us we have differentiated central services, our best-in-class global workforce and our making the right investment to post continued strong growth in the quarter and years ahead. Now, we would be happy to take your questions. Thank you.
