Analyst · Ken Hoexter, Merrill Lynch
Thank you for joining us this morning. Today, we are pleased to report on a year of improvement that was highlighted by our company's return to profitability. Tonnage increases in the early part of the year and a resulting revenue growth paved the way for improved pricing levels and return for the value ABF delivers to its customers. While a relatively small portion of our total revenue, our non-asset-based businesses had significant growth in both revenues and profits, thus making a meaningful contribution to 2011's positive results. Later, Judy will give her perspective on our recent performance and the factors that are affecting it.
Now I'd like to cover the details of our results, the fourth quarter and full year of 2011. Our fourth quarter 2011 revenue was $463.2 million, representing an increase of nearly 6% per day compared to last year. Our net income for the fourth quarter was $0.08 per share, excluding a $0.03 per share charge for a supplemental pension settlement related to an ABF executive retirement. These results compared to a net loss of $0.12 per share in the fourth quarter of 2010. This supplemental benefit plan was previously closed to new participants at the end of 2005. At the end of 2009, the benefits of this plan were frozen for all remaining participants.
For the full year of 2011, Arkansas Best had revenues of $1.91 billion, an increase of 15% per day, compared to 2010 revenues. Excluding the fourth quarter pension settlement charge, our net income for 2011 was $0.26 per share compared to a net loss of $1.30 per share in 2010. Our effective tax rate for 2011 was 33.3%. This includes the effects of an alternative fuels tax credit of approximately $1 million based on ABF's use of propane. Based on current law, this tax credit will not be available in 2012 due to its expiration at the end of 2011. In addition, a reduction in valuation allowances related to deferred tax assets also reduced our tax rate, as did nontaxable life insurance proceeds received in 2011. We anticipate our 2012 full year tax rate to be in a range of 38% to 42%.
Arkansas Best's operating cash flows for 2011 were $101 million, including depreciation and amortization of $74 million. Our net purchases of property and equipment totaled $46 million for the year. In addition, we financed $30 million of ABF's revenue equipment purchases. We did not purchase any treasury stock in 2011. We paid dividends on common stock of $3 million. Full details of our GAAP cash flow are included in our earnings press release.
At year end, our unrestricted cash and short-term investments totaled $175 million. Our restricted cash associated with collateral pledged to our workers' compensation letters of credit and performance bonds totaled $53 million. We had debt of $71 million, consisting of $44 million in equipment capital leases and $27 million in equipment notes payable. Arkansas Best had no borrowings under its accounts receivable securitization program. Availability under this program is $75 million.
At the end of the year, our stockholders' equity was $466 million. It was reduced in the fourth quarter by recognition of a $25 million other comprehensive loss. This reflects the impact of lower interest rate on a nonunion pension benefit obligation and weaker investment performance than anticipated in the nonunion pension plan assets. Based on these factors, we expect that our 2012 plan expense will increase. We'll know more specific details in the coming weeks after our actuaries complete their work. We'll share the 2012 changes when we release first quarter earnings.
Moving on to ABF's results for the quarter. ABF reported fourth quarter revenues of $422 million, an increase of nearly 5% per day compared to last year. ABF's quarterly tonnage per day declined 7.6% versus double-digit increases in last year's fourth quarter. ABF's fourth quarter operating ratio was 99.4% after excluding this year's pension settlement charges compared to 101.9% in fourth quarter 2010. For the full year of 2011, ABF reported revenues of $1.73 billion compared to $1.51 billion in 2010.
In 2011, ABF's total tonnage per day increased 4% versus last year. ABF's full year operating ratio was 99.7% after excluding this year's fourth quarter pension settlement charges compared to 103.9% in 2010.
Beginning with the current financial reporting period, we have expanded the operating segment details we are providing. We are doing this because of accounting rules that require public disclosure of business lines that meet certain operating profit thresholds. The Freight Transportation segment will consist of ABF's results. The 3 new categories consist of non-asset-based business segments, that on a combined basis, had growth of 30% in both revenues and profits in 2011.
I will also point out that we periodically review our work days to ensure accurate representation of per day business level changes and trends. We recently did that review again. As a result, we have reduced the January 2011 and December 2011 workday totals by a 1/2 day each. On both the segment changes and the work day change, David can provide a file that summarizes how this affects historical figures. And now, I'll turn it over to Judy for her thoughts about our quarter.
