Thanks, David. During the first quarter of 2015, we decided to refinance a significant portion of our high-coupon senior notes. As a result of the combination of make-whole redemption and a cash tender offer to purchase certain senior notes, the issuance of $1.8 billion of new senior notes, we reduced the weighted average interest rate of our portfolio by 100 basis points, extended the weighted average duration of these debt obligations by 3 years and reduced senior note debt by $181 million. The after-tax charge for the early extinguishment of debt related to these financing transactions was $344 million.
We also had 2 balance sheet items in the quarter. We had a true-up of the sale of our Wheelabrator subsidiary, which reduced our gain on sale and we impaired a short-lived landfill asset. Those 2 items negatively affected our earnings by $0.03 per share but had no effect on free cash flow. In the first quarter of 2015, our focus on reducing SG&A costs continues to bear fruit. Overall, SG&A cost declined $27 million compared to the first quarter of 2014. When you adjust 2014 for the operations that we divested, our year-over-year SG&A cost improvement was $15 million, consistent with our expectations for savings from our reorganization. With the strong results in the first quarter, we expect to achieve a full year SG&A -- our full year SG&A goals of reducing SG&A cost by reducing $60 million.
Turning to cash flow for the first quarter. Free cash flow was $285 million in the first quarter of 2015, an improvement of $22 million when compared to the first quarter of 2014, excluding the $221 million of free cash flow related to operations divested in 2014. Our capital expenditures for the quarter were $233 million, $33 million less than the first quarter of 2014. However, we spent about the same amount of capital as a percentage of revenue in both years. Given the strong start to the year, we still expect capital expenditures of approximately $1.2 billion to $1.3 billion. And free cash flow in 2015 is expected to be between $1.4 billion and $1.5 billion.
First quarter revenues were $3 billion. In addition to the $220 million impact from the divestitures and a $25 million impact from foreign currency fluctuations, the lower fuel surcharge negatively affected revenues by $36 million. Looking at internal revenue growth for the first quarter, our collection and disposal core price was 4.4%, with volumes declining 1.2%. This led to total company income from operations growing $21 million, operating income margin expanding expanded 130 basis points, operating EBITDA growing $11 million and operating EBITDA margin growing 140 basis points. Our collection lines of business continue to see the benefit of the price-volume trade-off. Our commercial core price was 6.6%, our industrial core price was 9.4% and residential achieved 2.1% core price. In addition to the continued strong momentum on pricing, we saw some positive momentum in volume. Commercial volumes were down 2.8% the first quarter of 2015 versus the decline of 4.8% in 2014, a 200 basis point improvement, and the best result in the past 7 quarters.
Industrial volumes improved 520 basis points from a negative 5.7% the first quarter of 2014 to a negative 0.5% in 2015. In April, we see industrial volume turning positive for the first time since the first quarter of 2013. Residential volumes declined 3.1% in the first quarter of 2015 versus a decline of 3.5% in 2014. But those losses were generally intentional as we pushed price over volume in our residential line. Overall, collection core price was 5.7%, with volumes declining 2.3%. The volume change was a 220 basis point improvement from the first quarter of 2014. This core price and volume led to income from operations growing almost $14 million and margin expanding 140 basis points.
In the landfill line of business, we saw the benefits of both positive volume and positive core price in the first quarter. We saw same-store average MSW rates increase year-over-year for the eighth consecutive quarter, up 1.2% from Q1 2014. Combine special waste and revenue-generating cover volumes, we're a positive 2.3%, MSW volumes grew by 5.7% and C&D volume grew 10.9%. Total landfill volume increased 1.8%. This led to income from operations growing $2.5 million, which is the eighth consecutive quarter growth, and margins grew 40 basis points. We believe the weather had some impact on landfill volumes. But the special waste pipeline looks strong, so we expect to see positive landfill volumes all year.
Looking at our recycling line of business. We had some challenges with low commodity prices and declining volumes. The impact of our recycling business was a negative $0.02 per share in the first quarter when compared to the first quarter of 2014. That decline would have been more than $0.05 per share if we've not been taking steps to improve contract and reduce operating costs. Those steps included: auditing inbound material to ensure compliance; renegotiating contracts to recover the appropriate our processing costs; and improving the quality of materials coming into our plants through consumer education. We were also able to improve the overall operating efficiency of our plants. As David mentioned, we expect our recycling operations are going to be a headwind all year, but we're seeing the results of our efforts to improve the operations. When commodity prices rebound, we're in a great position to see meaningful earnings improvements. In the meantime, we will curtail capital spending in our recycling operations, which will allow us to allocate more of our $1.2 billion to $1.3 billion of capital spend to our core solid waste assets.
Moving to operating expenses. We continue to see improvement in all of our cost lines. With respect to total operating costs, operating cost as a percent of revenue improved 130 basis points to 64% and improved $131 million in the first quarter after adjusting for divestitures. $83 million of the improvement related to lower diesel costs and lower recycling commodity rebates to our customers. We're also seeing a continued benefit from our service delivery optimization program in our labor costs as we see improved efficiency in all of our collection lines of business. Labor and related benefits improved $17 million when compared to the first quarter of 2014. The remaining savings were primarily driven by improvements in the subcontractor costs.
Finally, looking at our other financial metrics. At the end of the first quarter, our debt-to-total-capital ratio was 62.3%. Our expected 2015 weighted average cost of debt is 4.3% and the floating rate portion of our total debt portfolio was 9% at the end of the quarter. In the first -- in the fourth quarter, we returned -- first quarter, we returned $176 million to our shareholders through our dividend. As David mentioned, we expect to return more cash to our shareholders in the second quarter as we look to repurchase shares to offset dilution.
Our income tax rate in the first quarter was 41%. Adjusted for items excluded in our as-adjusted results, the tax rate was 34.2%, which is closely in line with our expected tax rate of approximately 35% for the full year. To summarize our quarter with the exception of recycled commodity prices, virtually all of our financial and operating metrics were tracking ahead of our internal expectations and our previous guidance. We expect that to continue throughout 2015.
I want to thank all of our employees for their hard work in the first quarter. I know that they will continue their focus to make 2015 a successful year. And with that, Tanisha, let's open the line for questions.
