Thanks, Kevin, and thanks, to each of you for joining us to discuss fourth quarter and year-end performance. With me today is our CEO, Teddy Gottwald. I have a few planned comments, after which we'll open the lines for your questions.
As a reminder, some of the comments we will 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 2010 10-K. We plan to file our 2011 10-K in late February. That document will contain significant details on the operations of our company and as the result of a long work by our team to publish it from tagging data from XPRL, to mindnumbing details required in the footnotes. Thanks to each of you for doing that. Please take the time to read through it to get a better understanding of our performance.
I'm going to cover the first -- the quarter first and then move on to the year. Net income for the fourth quarter was $33.7 million, or $2.51 a share, compared to net income of $49.4 million, or $3.47 per share for the same period last year. The interest rate swap that we mark-to-market had an adverse impact of $0.37 per share in the quarterly comparisons. Without the swap, our earnings per share were $2.57 compared to $3.16 for last year's fourth quarter. Our net income without the swap was $34.5 million compared to $45 million last year.
Petroleum Additives net sales for the quarter increased to $499 million, which is an increase of about 10% over last year's performance, while current shipped were actually 2% lower. We believe that the decline in shipments in the fourth quarter includes the traditional volume pattern, the effect of reduction of inventory levels by some of our customers, as well as some softness in demand influenced by economic issues around the world predominantly Western Europe. It is difficult to know the exact buying behavior of many of our customers.
We ended 2011 with some announced reductions in base oil. In the past we have seen some hesitancy from our customers to purchase additives when base oil is dropping as they manage their inventories for the possibility of future drops in that very important raw material. This was the pattern that we saw at the end of 2008, although this drop is nowhere of the same severity. As in 2008, the drop was in the Lubricant Additives area as our customers hold a relatively small amount of fuels inventory. The sales increase was due to pricing currency with lower shipments dragging it down somewhat. During the quarter, Petroleum Additives posted an operating profit of $59.3 million compared to $72 million in the fourth quarter of last year.
I'd like to spend a little time explaining the things we see as a management team when we look at that quarterly result. First off, the volume was lower than we were anticipating. The first question we ask ourselves when this happens centers around our customers and their satisfaction with us. As a matter of fact we ask that question ourselves every day. We know we did not lose any significant business during the quarter, so we conclude the volume drop is one of several things. It could be inventory adjustments by them, our customers; economic slowdown which affects their demand or a combination of the 2; or other factors that may influence their buying decisions. These lower volumes led us to run our plants at lower rates in order to better manage our overall inventory levels. Running at that lower rate resulted in a higher than normal level of unabsorbed plant cost going directly to the P&L in the quarter.
On top of all of that, we set the charge for our contingency position we had on a certain raw material and continued on our planned increased spending pace in R&D and F&A to support our customers. We generally do not go into so much detail about onetime items because every quarter has its shares of ups and downs in running our global business. I had mentioned these this quarter because they total in the $8 million to $10 million range and not the normal plus or minus $2 million that may characterize a more normal quarter. All in all, our Petroleum Additives business is running well and we are pleased with its performance.
The quarter also included a couple of million dollars at the corporate S&A level that occurred from time to time. We contributed an extra $1 million to a charitable trust during the quarter, and had a bittersweet event of charging our P&L with an extra $1 million associated with marking certain obligations to market that are based on our stocks performance. We did not repurchase any stock in the fourth quarter and ended the year with 13.4 million shares outstanding.
Now I'm going to move on to the year. It was an outstanding year for our company virtually across every variable we track. Net income for the year increased to $206.9 million, or $15.09 per share, compared to net income of $171 -- $177.1 million or $12.09 a share last year 2010. The earnings for the current year and prior-year periods include the impact from an interest rate swap, while the current year also includes the gain on the legal settlement. You will notice that there is a table on the face of the press release which details the impact of those 2 items. If you look at the last row, the one that excludes the legal settlement and swap, you can see that net income in 2011 was $193.7 million versus $183.4 million in 2010. That represents an increase of 5.6%. A comparable increase in earnings per share was 12.8%, which included the impact of our buyback activities during 2011.
Net sales for the year totaled $2,149,000,000. This was the first time we exceeded the $2 billion mark. Revenue for 2011 was 19.6% higher than 2010 and included the benefit of a 6% improvement in tons shipped. We had records in revenue, volume, profits and safety performance. All of our regions saw improved profit performance as did most of our product lines. We are proud of that performance and know it is the result of a global team effort. We continue to invest in our R&D programs as we believe that is a key to our continued long-term success. We spent $105 million in R&D in 2011 compared to $91 million in 2010. This was a 16% increase in purposeful spending. During the year, we expanded our presence in the Asia-Pacific region with supply positions, additional sales coverage and additional R&D support. Our team performed well, served our customers with distinction and are prepared to match that performance in 2012.
There are few tables attached to the press release and I'll cover just a couple of items, so take a look at the balance sheet first. The balance sheet has a lot of moving parts and the 10-K is the source to gain a more complete understanding what's driving each one of those. For the quarter, we reduced total debt by $32 million as our business generated cash in excess of our needs to run our business, manage our capital campaign and pay our dividend of $0.75 per share.
On the cash flow, most of the cash flow statement for the year is a basic continuation of the pattern we posted for the first 3 quarters. The only item of note for the fourth quarter is that we had a return of about $26 million in the working capital section. This was primarily related to accounts receivable which were down a fair amount from the end of the third quarter, since sales were down on a sequential basis. On an annual basis, working capital continued to increase to support our business with us having $62 million more dollars in that area than we did at the beginning of the year.
Our business continued to generate significant cash as evidenced by our EBITDA, which was $343 million as adjusted, compared to $325 million for last year on the same basis. The 'as adjusted' comment I made removes the benefit of a one-time legal settlement. These numbers can be found on the non-GAAP reconciliation on the last page of the press release. With total debt ending at $243.6 million, we ended the year with a debt-to-EBITDA ratio of 0.7. We continue to operate with very low debt leverage which affords us a lot of flexibility in executing our business plans and in capitalizing on opportunities as they may arise.
We begin 2012 with a very positive view of our business and the customer focused approach, we believe, has helped 2011 be a record-setting year. We believe the fundamentals of how we run our business, the safety first culture, customer focused solution, technology driven product offerings, a world-class supply chain capability, and a regional organization structure to better understand our customer needs will continue to pay dividends to all of our stakeholders. We expect 2012 to be more profitable than 2011 as we project an increase in volume, revenue and net income. There has been no significant change in the positive fundamentals of our Petroleum Additives business. We do not consider the fourth quarter softness to be indicative of the year to come. We expect industry demand to continue to grow at about a 2% a year rate and we plan to exceed that rate. Our view on margins has not changed. When you look at our year's performance and you add back the one-times, we exceeded 15% margin for the year. We believe the business should be able to continue to deliver in that range.
Over the past several years we have made significant investments to expand our capabilities around the world. These investments have been in people, research centers and production capacity. We intend to use these new capabilities to improve our ability, to deliver the goods and service that our customers value and to expand our business and profits. In summary, we expect the business practices that have produced the outstanding results of the past 2 years will continue in 2012.
As our business continues to generate significant cash, beyond what is needed for the expansion and growth for our business lines, we regularly look at other ways to deploy that, including internal opportunities, both from a geographical and a product line point of view. We continue our efforts in investigating potential acquisitions as both our use for this cash and to generate shareholder value. As we stated, our primary focus in the acquisition area remains in Petroleum Additives industry as it is of our view that this industry will provide the greatest opportunity for a good return on our investment while minimizing risk. We remain focused on this strategy and will evaluate any future opportunity. Nonetheless we are patient in this pursuit and intend to make the right acquisition when the opportunity arises. Until an acquisition materializes, we will build cash in our balance sheet and will continue to evaluate all our current uses of that cash to enhance shareholder value including stock repurchases and dividends.
That ends my prepared remarks. Kevin, can we open the lines for any questions.
