Thanks, Tim, and thanks to everyone for joining us to discuss our second quarter performance at a little bit unusual time for us. With me today is Teddy Gottwald, and I have our planned comment, and then we'll open the lines for your question.
As a reminder some of the comments we'll make today are forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995. We believe we base our statements on reasonable expectations and assumptions within the bounds of what we know about our business and operations. However, we offer no assurance that actual results will not differ materially from our expectations due to uncertainties and factors that are difficult to predict and beyond our control. A full discussion of these factors can be found in our 2011 10-K. We filed our 10-Q this morning. It contains more details on the operations of our company. Please take time to review it.
Net income for the second quarter improved to $55 million, or $4.12 a share, an increase of 6% over net income for the second quarter of last year. For the first half of this year, net income increased to $122 million, or $9.09 a share, an improvement of 20% compared to the net income of the first half of last year. Earnings per share for the second quarter and the first half increased 9% and 24%, respectively. Earnings for both quarters of this year include a charge for an interest rate swap and for the early extinguishment of debt. Excluding these items from all comparable periods, earnings for the second quarter of 2012 improved to $63 million, or $4.69 a share, an increase of 15% over earnings for the second quarter of last year. The details of this information is highlighted in yesterday's earnings release.
Sales of Petroleum Additives for the second quarter were $584 million, which is 2% higher than last year's second quarter. Shipments for the second quarter were about 7% lower than last year's second quarter and about 5% higher than the first quarter of this year. I'd like to point out that the second quarter of 2011 shipments were the highest quarter in the Petroleum Additives' recent history, while this year's second quarter is the second highest. When looking at the second quarter to second quarter comparison of revenue, revenue increased $43 million due to pricing mix, decreased $21 million due to volume and decreased $11 million due to foreign exchange impacts. Petroleum Additives segment operating profit for the second quarter of this year increased to $96.9 million, a 13% improvement over the second quarter of last year. For the second quarter, our operating profit margin was 16.6%. For the 4 quarters that ended in June, our operating margin was 15.8%. Both of these numbers, the 16.6% and the 15.8%, are within our expectations of the performance of this business.
We did not repurchase any stock in the second quarter and currently have 13.4 million shares outstanding. In the July Board meeting, the Board authorized a total of $250 million for stock repurchases. This authorization is good until the end of 2014. This authorization, which is good for 2.5 years, is consistent with previous authorization levels, which have averaged about $100 million per year. The previous authorization, which had $50 million unused, was canceled. As you may recall, we entered into a new $650 million, 5-year, unsecured revolving credit facility, which provides us with significantly lower cost to borrowing and increased operating flexibility to execute our plans.
Since we established that new facility, we funded the early redemption of all of the bonds we had outstanding at the end of the year. These bonds had a principal amount of $150 million and a coupon rate of 7 1/8% and were due in December of 2016. Those bonds were redeemed on April 16.
Additionally, we paid off the $63 million mortgage loan secured by the Foundry Park office building. While we have incurred onetime costs to put this facility in place, you can see the benefit of it in the interest expense section of the P&L, with the second quarter to second quarter comparison showing over a $2 million benefit. We had good cash flow generation in the quarter, with $94 million of EBITDA. As detailed in the press release financials, there were quite a few items in the quarter associated with closing out the old loans and establishing the new ones. Working capital for the year has used about $50 million of cash, and we have spent $17 million on capital expenditures. We have reduced our debt by $54 million since the end of last year. We expect capital expenditures to be in the $45 million range for the year. We continue to operate with very low debt leverage. Our debt to EBITDA at the end of the quarter was well below 1x ratio.
We recently announced the planned construction of a new additive manufacturing facility on Jurong Island in Singapore. The multiyear investment will be fully owned and operated by Afton. This investment emphasizes our continuing commitment to the expanding Asia-Pacific market. This addition will provide us with an excellent combination of research and development, sales and marketing support and manufacturing, all in the region. This facility will also improve the security of supply and reduce lead times of delivery of our products to the customers in that region. We anticipate an initial investment in excess of $100 million, with significant spending beginning in the second half of 2013. We plan to start up the plant in mid-2015.
At the same time, we also announced Dr. Warren Huang's intention to retire on April 1 of 2013, and the appointment of Rob Shama to replace him as President of Afton Chemical on January 1 of 2013.
We've begun 2012 with very good results. We believe the fundamentals of how we run our business, our long-term view, safety-first culture, customer-focused solutions, technology-driven product offerings, world-class supply-chain capability and a regional organization to better understand our customers' needs, continues to pay dividends for all of our stakeholders. We expect 2012 to be more profitable than 2011. Our business is executing well and there has been no significant change in the fundamentals of the Petroleum Additives business. We expect the long-term industry demand to continue to grow at a rate of 1% to 2% volume improvement per year. While we plan to exceed that rate in the long run by focusing on areas of the world where we are underrepresented in delivering products that specifically meet the needs of those areas, we are not certain that this year's overall market growth rate will be that high. We have seen some softness in demand recently that we believe is associated with the global economic slowdown and uncertainty around the world. We currently expect that our demand in the second half of 2012 will be slightly lower than the first half by a few percentage points. As a reference, in 2011 the second half had volumes over 10% lower than the first half of 2011. I'd like to emphasize the fact that the near-term demand has become more difficult to predict in our business. Given this view of the second half, the year-on-year comparison of volumes would have 2012 roughly flat with 2011.
Those are all the comments I have, and, Kevin, I'd like to open the lines for any questions.
