Arkansas Best Corporation Announces 4th Quarter And Full Year 2006 Results

FORT SMITH, Ark., Jan. 24 /PRNewswire-FirstCall/ -- Arkansas Best Corporation (Nasdaq: ABFS - News) today announced fourth quarter 2006 income from continuing operations of $14.2 million, or $0.56 per diluted common share, compared to $29.5 million, or $1.15 per diluted common share in the fourth quarter of 2005. Arkansas Best's revenue during the fourth quarter of 2006 was $449.0 million, a per-day decrease of 3.9% compared to the fourth quarter of 2005.

"Despite a challenging economic environment in the last few months of the year, Arkansas Best closed the year with a strong financial position, and ABF generated its fifth best yearly operating ratio since the industry was deregulated in 1980," said Robert A. Davidson, Arkansas Best President and Chief Executive Officer.

For the full year of 2006, Arkansas Best reported income from continuing operations of $3.16 per diluted common share compared to $3.99 per diluted common share in 2005. Excluding a previously disclosed after-tax pension settlement accounting charge of $0.24 per share, full year 2006 earnings from continuing operations were $3.40 per diluted share. This compares to full year 2005 earnings from continuing operations of $3.61 per diluted share, after adjusting for a $0.38 per share gain on the sale of properties to G.I. Trucking Company. Arkansas Best's 2006 full year revenue was $1.86 billion, a per-day increase of 6.6% over 2005 full year revenue from continuing operations of $1.75 billion.

ABF Freight System, Inc.®

ABF Freight System, Inc. had fourth quarter 2006 revenue of $436.1 million, a per-day decrease of 4.3% compared to fourth quarter 2005 revenue of $455.5 million. ABF's total tonnage per day during the fourth quarter of 2006 decreased by 6.8% compared to the same period last year. ABF's operating income during the 2006 fourth quarter was $20.8 million compared to $48.4 million in the same period last year. ABF's fourth quarter 2006 operating ratio was 95.2% compared to its fourth quarter 2005 operating ratio of 89.4%.

"In October and continuing into November, traditionally among the busiest months of the year, ABF experienced a sudden and dramatic reduction in business that mirrored conditions throughout the trucking industry," said Mr. Davidson. "This year's sequential decline in total weight per day from September to October was the largest, by far, in over twenty years. It occurred at a time when ABF was operationally prepared for strong seasonal business and for maintaining the aggressive customer service level improvements initiated in the third quarter of 2006. In addition, ABF was, and continues to be, in the midst of further expansion of its regional service under the Regional Performance Model (RPM). As a result, we were delayed in reducing labor and other costs from the ABF network, and our fourth quarter operating ratio was negatively impacted."

"The negative operating leverage ABF experienced in the fourth quarter was reminiscent of ABF's 2001 results compared to 2000, when similar tonnage declines resulted in a significant increase in ABF's operating ratio," said Mr. Davidson. "In a cyclical industry, ABF has managed through previous periods of declining tonnage by maintaining pricing discipline and closely monitoring costs. We are doing that now. As in the past, when tonnage levels improve, we expect that profitability should return to traditional levels."

"This year's fourth quarter operating ratio deteriorated by about one percentage point due to investments in the RPM initiative, as we anticipated," said Mr. Davidson. "This is in addition to the negative impact of declining tonnage on our quarterly results. Workers' compensation costs added 0.5 percentage points to ABF's operating ratio compared to unusually favorable expenses in the last three months of 2005. This year's fourth quarter workers' compensation costs were in line with expectations and below the ten- year average as a percent of revenue. However, during the fourth quarter of 2005, these costs were unusually low because of favorable claim and severity trends and because of a reserve reduction related to positive information regarding claims covered by the California guaranty fund."

"A large part of ABF's past financial success has been the result of closely matching labor costs with available freight levels. ABF has taken steps to scale expenses to available tonnage although we do expect unit labor costs to be higher until industry tonnage levels recover," said Mr. Davidson. "As we move through 2007, ABF has the flexibility of selling a greater amount of revenue equipment, if needed, in order to better match its fleet size to current business levels."

Total billed revenue per hundredweight was $25.07, an increase of 3.2% over last year's fourth quarter figure of $24.30. "Despite a very challenging freight environment, ABF's pricing has remained very good," said Mr. Davidson. "During a quarter when more than a third of ABF's contract and deferred pricing agreements renewed, the average price increase on that portion of ABF's business was 4.6%. This is encouraging and an indication of the success of ABF's focus on individual account profitability. It also demonstrates that ABF's customers recognize the value ABF offers as a result of lower freight claims, improved transit time reliability, better cargo handling, superior technology and a higher level of personal customer service."

For the full year of 2006, ABF's revenue was $1.81 billion, a per-day increase of 6.4% over 2005 revenue. ABF's 2006 operating ratio was 92.5%, after adjusting for the settlement accounting charge, versus an operating ratio of 90.9% in 2005. ABF's 2006 operating income was $125.1 million versus $155.7 million during 2005. Excluding the settlement accounting charge, ABF's 2006 operating income was $135.3 million. Total tonnage per day in 2006 increased 1.5% over 2005. Total billed revenue per hundredweight for 2006 was $25.03, an increase of 4.7% over last year's full year figure of $23.90.

ABF's 2006 full year cargo claim ratio, a measure of net cash payouts to revenue, was 0.76%, the best ABF has experienced in over twenty years. "We believe this is one of the lowest cargo claim ratios in the LTL industry and an illustration of ABF's reliable freight handling and superior customer service," said Mr. Davidson. In addition, ABF's 2006 Department of Transportation (DOT) reportable accidents per million road miles decreased by 14% versus 2005 and ABF's 2006 DOT reportable accidents per million city miles decreased by 25%. "These significant improvements in reducing vehicular accidents confirm ABF's reputation as the safest carrier on our nation's highways," said Mr. Davidson.

In early January, ABF began the marketing of the Central and Southern portions of its Regional Performance Model (RPM), which now provides improved next-day and second-day services in the eastern two-thirds of the United States. The RPM network, which features enhanced flexibility and operational efficiency for short-haul freight transportation, includes regional linehaul operating models that are separate from and parallel to those of ABF's national linehaul network. "ABF continues to develop the RPM infrastructure in order to provide competitive service in these lanes," said Mr. Davidson. "ABF's sales force and our other employees are enthusiastic and fully engaged in this exciting new effort. Our customers are pleased that ABF is able to extend its high level of service and value to shorter-haul shipments."

"The RPM initiative did not have a significant impact on our system revenue totals in the fourth quarter of 2006. Until it gains traction, possibly not until the latter half of this year, we do not anticipate that RPM will have a meaningful impact on revenue. However, we will continue the operational investments necessary to fully implement RPM. As in our traditional long-haul markets, ABF will sell higher value rather than cheaper prices. As a result, market penetration will require patience, but the additional business will be more profitable and lasting customer relationships will be developed," said Mr. Davidson. "The current economic environment hasn't been a particularly good time to begin this important initiative. Nevertheless, it's vital for our company's future, and the sooner we start, the sooner we reach our goals. We believe that enhanced regional capabilities and improved service throughout our system are excellent investments that, over time, will yield solid results."

Capital Expenditures

Arkansas Best estimates 2007 net capital expenditures will be approximately $110 million to $135 million. Total net capital expenditures in 2006 were $136 million. Other than purchases related to the RPM initiative, the 2007 capital expenditure plan does not include expansion of the road tractor and doubles trailer fleets. Road and city equipment replacements are expected to be $63 million, and investments in RPM should be $20 million.

The low-end 2007 capital expenditure plan is below our net capital expenditures for 2006 because in 2007 ABF does not expect to purchase rail trailers and is adding less city delivery equipment.

There is the potential for additional capital expenditures amounting to as much as $25 million above the low-end figure of $110 million. These could include real estate opportunities throughout ABF's network and purchases of city equipment, if needed.

Arkansas Best's depreciation and amortization for 2007 is estimated to be approximately $75 million to $80 million.

Common Stock Purchase

During the fourth quarter of 2006, Arkansas Best purchased 250,000 shares of its common stock in the open market for an aggregate cost of $10.1 million. These common shares were added to the company's treasury stock. Since January 2003, Arkansas Best has purchased 1,493,150 shares totaling $51.9 million. Under a program announced in July 2005, Arkansas Best currently has authorization to purchase up to an additional $23.1 million of its common stock. Arkansas Best plans to continue making open-market purchases of its stock on an opportunistic basis.

Pension Plans

Arkansas Best has an unfunded supplemental pension benefit plan for the purpose of providing supplemental retirement benefits to executive officers of the company. As a result of benefit distributions under this plan, in 2006 Arkansas Best recorded pre-tax settlement accounting charges of $10.2 million, or $0.24 per diluted common share, net of taxes. Likewise, an upcoming distribution of benefits to another retiring officer will result in Arkansas Best recording, in the first quarter of 2007, pre-tax charges estimated to be $1.1 million, or $0.03 per diluted common share, net of taxes. Effective December 16, 2005, Arkansas Best's supplemental pension benefit plan was closed to new participants, and executive officers added since that date are participating in a three-year, performance-based plan.

In order to recognize the funded status of Arkansas Best's nonunion defined benefit pension and other postretirement benefit plans on its balance sheet, as now required by Financial Accounting Standards Board Statement No. 158, Arkansas Best's stockholders' equity was reduced, net of deferred taxes, by $34 million as of December 31, 2006.

Non-GAAP Financial Measures. The company reports its financial results in accordance with generally accepted accounting principles ("GAAP"). However, management believes that certain non-GAAP performance measures and ratios utilized for internal analysis provide financial statement users meaningful comparisons between current and prior period results, as well as important information regarding performance trends. Certain information discussed in this press release and in the scheduled conference call could be considered non-GAAP measures. Non-GAAP financial measures should be viewed in addition to, and not as an alternative for, the company's reported results.
