Okay. Thanks, Bill, and good morning, everybody. As usual, I'll begin by discussing the top line of each of our 2 segments, which is equipment leasing and Seamap. Then I'll follow up with the discussion of the profitability of each of the segments and then conclude with a discussion of our consolidated results and our financial position.
First, let me review our equipment leasing segment, which includes not only our core leasing business, but also non-Seamap equipment sales such as occasional sales of our lease pool equipment, new seismic equipment that we acquire from third parties, sales of heli-transport equipment and sales of new Hydrographic and Oceanographic equipment from our Australian subsidiary, SAP.
In our core leasing business, revenues in the first quarter were up 25% year-over-year to $21 million. We saw year-over-year improvement in most areas of the leasing business with Canada and marine leasing being the most significant. However, we also saw improvement in the U.S., Russia, Europe and South America. We had expected even more improvement in South America. However, due to the weather issues in Colombia that Bill mentioned, we have seen certain projects delayed until later in the year. Now in Latin America, the rainy season typically occurs during the late winter/early spring time period. So while there's nothing unusual about the seasonal time of the rain there, it has been unusually heavy this year. We estimate that the delayed leasing revenues related to this amount to about $2 million.
As expected, and I think as we mentioned in the last quarter's call, we did see some softness in leasing revenues in certain areas as compared to the fourth quarter of fiscal 2012. Coming off a very strong fourth quarter, we had to test, repair and reposition a great deal of equipment during the first quarter. Due to that and the seasonal factors, we did experience lower leasing revenue sequentially primarily in the U.S., South America and in Europe. As Bill also mentioned, we do seem to be experiencing less seasonal fluctuation in our leasing business than in the past. That being said, seasonal fluctuations will continue. We do expect our second quarter leasing revenues to be sequentially lower from the first quarter as has been the case historically. Contracting to bid and acquiring activity in the leasing business continue to be good and to meet our overall expectations. Our sales of lease pool[ph] equipment increased to $2.3 million in this quarter compared to $335,000 in the same quarter last year. Other equipment sales, which include sales from SAP and heli-picker equipment were $747,000 in the first quarter compared to $1 million for the same quarter a year ago.
We'll now turn to our Seamap segment, which again designs, manufactures and sells a variety of products and systems used in marine seismic applications. Seamap had it's best quarter ever with revenues up 26% to $10.5 million from $8.3 million at the same quarter a year ago and up 44% from the fourth quarter of 2012. During the quarter, we shipped 2 GunLink 4000 systems and 3 BuoyLink RGPS systems. Sales of streamer weight collars, spare parts and support and service work also continued to show solid results. As Bill told you earlier, additional deliveries had been scheduled but had to be delayed to our customers' requirements. These some odds and ends amounted to more than $2.5 million of delayed revenues, all of which has now been delivered.
Now let me discuss the profitability of each of the segments. Gross profit for equipment leasing segment was $10.9 million in the first quarter compared to a gross profit of $9 million in the same quarter a year ago. The first quarter rev gross profit margin in the leasing segment was 45% compared to 50% of last year's first quarter. Now this change was due to higher depreciation costs arising from our investment of new equipment, as well as increased support costs attributable to the higher, leasing activity. Gross profit for our Seamap manufacturing business was $6 million for the first quarter compared to $4.8 million for the same quarter a year ago. This represents a gross profit margin of 55% and 57%, respectively. Now, this nominal difference was the result of changes in product mix. Our overall gross profit for the first quarter rose 21% to $16.9 million from $14 million in the same quarter a year ago. And the overall gross profit margin in the quarter was 49% compared to 53% in last year's -- in the same quarter a year ago. Now let me touch on just a few items in our other items in our P&L. Our general and administrative expenses for the first quarter were $5.3 million as compared to $4.6 million in the first quarter of last year. As a percentage of revenues, G&A expenses declined to 15.4% in this year's first quarter from 17.5% in last year's quarter. Our tax provision for the quarter was $2.6 million, which is an effective run -- tax rate of just under 24% compared to $2.4 million or about a 28% effective rate in the same quarter a year ago. Our effective tax rate is lower than the U.S. tax quarter rate primarily due to the effective lower tax rates in foreign jurisdictions.
Our first quarter EBITDA was $19.8 million compared to $15 million in last year's first quarter or 57% of revenues in both periods. Our adjusted EBITDA, which excludes stock-based compensation expense, was $20 million this quarter as compared to $15.3 million in the same period last year. Now keep in mind that EBITDA and adjusted EBITDA are non-GAAP measures and are reconciled to reported income and cash provided by operating activities in the financial tables in yesterday's press release.
Overall, we recorded net income of $8.5 million or $0.63 per diluted share in the first quarter of this year compared to $6.1 million or $0.58 per diluted share for last year's first quarter. Now we estimate that the approximately $4.5 million in delayed revenues that we've discussed resulted in lower net income in the first quarter of about $2.4 million or about $0.18 per diluted share. In addition, this year's first quarter did include the impact of the 2.3 million additional shares of common stock that were issued in our June 2011 public offering. Let me just make a few comments about our financial position and then I'll turn the call back over to Bill. During the first quarter, fiscal quarter, we added just under $16 million in new lease equipment. About $14 million of this relates to a purchase of used equipment we made late in the quarter. This equipment consists of approximately 15,000 stations or 45,000 channels of 3D component recording equipment and about 3,000 channels of single component equipment. But most of this equipment has not yet been deployed, excuse me. However, we were able to obtain the equipment at a very favorable price. This purchase gives us a very strong position of 3D component equipment, and we'd expect strong demand for it the later in the year, including for the Canadian winter season. For the balance of 2013, we expect to continue to selectively edge our lease pool base on industry trends, customer demand and opportunities that may arise. We currently expect our lease pool additions for all of fiscal 2013 to total between $35 million and $40 million. Mitcham's overall financial and liquidity position remains very strong. We continue to generate good cash flow from operations, which amounted to just about $17.9 million in the first quarter of fiscal 2013. At the end of the quarter, we had $50.1 million of working capital, and cash and cash equivalents of $17.5 million. As of April 30, 2012, we had about $19.2 million outstanding under our $35 million revolving credit facility. And with that, I'll turn things back over to Bill.
