Potlatch Reports Fourth Quarter and Full Year 2008 Results

SPOKANE, Wash--(BUSINESS WIRE)--February 12, 2009--Potlatch Corporation (NYSE:PCH) today reported financial results for the fourth quarter and full year ended December 31, 2008.

On December 16, 2008, Potlatch successfully completed the spin-off of its pulp-based manufacturing businesses and the Lewiston, Idaho lumber mill into a new company, Clearwater Paper Corporation. “We accomplished a major strategic objective in 2008 with the successful spin-off of Clearwater Paper in the 4^th quarter. Potlatch is now clearly positioned as a 'pure play' timber REIT,” said Michael J. Covey, chairman, president and chief executive officer. The results for Clearwater Paper for the quarter and year through December 15, 2008, are shown as discontinued operations.

Q4 2008 Financial Summary

• The company recorded earnings from continuing operations for the quarter of $5.4 million, or $0.14 per diluted common share, compared to earnings of $7.5 million, or $0.19 per diluted common share for Q4 2007.
  • Q4 2008 results from continuing operations included higher operating income from the Resource segment due to increased harvest levels compared to Q4 2007. Offsetting this improvement were lower earnings from the Real Estate segment primarily due to fewer acres sold in Q4 2008 versus Q4 2007, and a larger loss from the Wood Products segment.
• Including discontinued operations, we recorded a net loss of $4.3 million, or $0.11 per diluted common share, compared to earnings of $11.2 million, or $0.28 per diluted common share, for Q4 2007.
  • Discontinued operations for both periods included the effects of the spin-off of the Clearwater Paper operations and the closure of our Prescott, Arkansas lumber mill. Results for Q4 2008 reflected a loss of $9.8 million related to discontinued operations compared to earnings of $3.7 million in Q4 2007.

“The Resource segment had solid results for Q4 2008, primarily due to higher harvest levels in both the southern and northern regions during the quarter. In comparing to Q4 2007, sawlog pricing was lower in both regions by approximately 16 percent, while pulpwood pricing increased slightly in the northern region and remained relatively flat in the southern region.

“The Real Estate segment had lower income in the fourth quarter compared to Q4 2007 primarily due to decreased acreage sold. Approximately 2,000 acres were sold in Q4 2008, compared to approximately 6,900 acres in Q4 2007.

“The Wood Products segment continued to experience extremely weak market conditions, with a segment operating loss of $11.4 million in Q4 2008 compared to a loss of $5.0 million in Q4 2007. Due to the continuing weak market conditions, most of our lumber mill operations were down from one to two weeks during the fourth quarter. Our Post Falls, Idaho particleboard facility was shut down for five weeks during the quarter. Most of our wood products mills continue to run at reduced production levels since the beginning of this year. We expect to experience continued weak market conditions well into 2009, and are taking steps to mitigate the losses,” concluded Mr. Covey.

2008 Full Year Financial Summary

• Earnings from continuing operations for the full year 2008 were $68.8 million, or $1.73 per diluted common share, compared to $72.3 million, or $1.84 per diluted common share for the full year 2007.
  • Earnings for 2008 from continuing operations included pre-tax charges totaling $3.0 million ($1.8 million after-tax) related to settlements with the direct and indirect purchaser classes in the OSB antitrust lawsuit. Both settlements have been given final court approval.
  • Earnings for 2007 from continuing operations included a $2.7 million ($2.3 million after-tax) restructuring charge for the Resource segment.

• Net earnings for the full year 2008, including discontinued operations, were $52.6 million, or $1.32 per diluted common share, compared to $56.4 million, or $1.43 per diluted common share, for the full year 2007.
  • Discontinued operations for both periods included the effects of the spin-off of the Clearwater Paper operations and the closure of the Prescott, Arkansas lumber mill. For 2007, discontinued operations also reflected the sale of the company’s hybrid poplar tree farm in Boardman, Oregon. Results for full year 2008 reflected a loss of $16.2 million related to discontinued operations compared to a loss of $15.9 million for 2007.

Q4 2008 Business Performance

Resource

• Operating income for the segment was $15.9 million, compared to $10.6 million earned in Q4 2007.

Southern Region

• Fee harvest levels increased 95% in Q4 2008 compared to Q4 2007, as harvest levels in the region were reduced in Q4 2007 to avoid a buildup of log inventories, coupled with favorable logging conditions in Q4 2008. Fee harvest levels in Q4 2008 increased 21% compared to Q3 2008, due to reduced harvest levels in Q3 2008 resulting from extremely wet conditions from hurricane events.
• Sawlog pricing was lower by 16%, while pulpwood pricing remained flat in Q4 2008 compared to Q4 2007. Q4 2008 sawlog prices increased 4% when compared to Q3 2008, while pulpwood pricing remained flat.

Northern Region

• Fee harvest levels increased 12% in Q4 2008 compared to Q4 2007 due to ideal fall logging conditions in Idaho. Fee harvest levels decreased 34% compared to Q3 2008, which is seasonally the Northern region’s strongest production quarter.
• Sawlog pricing was lower by 16%, while pulpwood pricing increased 3% in Q4 2008 compared to Q4 2007. Sawlog prices were 17% lower when compared to Q3 2008, primarily due to a lower percentage of cedar sawlogs sold in Q4 2008 coupled with lower mixed sawlog pricing.

Real Estate

• Operating income for the segment was $0.3 million in Q4 2008, compared to $7.9 million in Q4 2007.
  • Land sold in Q4 2008 in Arkansas, Idaho, Minnesota and Wisconsin totaled approximately 2,000 acres at an overall average price of nearly $1,440 per acre.
  • Land sold in Q4 2007 totaled approximately 6,900 acres at an overall average price of approximately $1,710 per acre. More HBU/development acres were sold in 2007 than 2008.

Wood Products

• The segment reported an operating loss of $11.4 million for Q4 2008, compared to a loss of $5.0 million for Q4 2007.
  • Lumber results were negatively impacted by the continued downturn in the housing market, resulting in lower net sales prices and shipments. Lower revenues were somewhat offset by lower production costs.
  • Many of our mills were operating with reduced production schedules during Q4 2008.

New Credit Agreement

During the fourth quarter, Potlatch replaced its existing revolver with a new $250 million revolving credit facility. The new revolver, which is secured with a portion of the company’s Idaho timberlands, has a five-year term. “In spite of the difficult credit environment, we were successful in securing a new revolver,” concluded Mr. Covey.

Impact of Clearwater Paper Spin-off on Balance Sheet

As noted above, Potlatch successfully spun off Clearwater Paper in the fourth quarter of 2008. Although the year-end 2008 balance sheet excludes Clearwater Paper assets and liabilities, the year-end 2007 balance sheet still includes those assets and liabilities. Further, as part of the spin-off, Clearwater Paper retained the obligation to repay $100 million of credit sensitive debentures which are on Potlatch’s balance sheet. Since Potlatch is ultimately responsible for repayment of the debentures in the event Clearwater Paper fails to pay them when due, Potlatch will continue to represent the liability on its balance sheet as a current installment on long-term debt, but it is offset by a $100 million current note receivable from Clearwater Paper. Once Clearwater Paper repays the credit sensitive debentures, both the liability and the asset will be removed from Potlatch’s balance sheet.

In addition, on the Statements of Operations and Comprehensive Income (Loss), the significant "Other comprehensive loss" amounts for 2008 are primarily attributable to the negative performance of our defined benefit pension plans as a result of the steep downturn in the stock market in the fourth quarter of the year.

Dividend Distribution

During the fourth quarter, Potlatch paid a regular quarterly cash distribution on the company’s common stock of $0.51 per share. The spin-off of Clearwater Paper resulted in a common stock distribution of one share of Clearwater Paper common stock for every 3.5 shares of Potlatch common stock.

Outlook

“Looking ahead, our Resource business in the Southern region remains relatively stable, but we are experiencing downward price pressure in the Northern region as sawmills curtail production. Fortunately, our geographic diversity allows us to balance harvest levels depending on regional strengths and weaknesses. Our Real Estate business continues to operate reasonably well in this challenging economic environment. In fact, despite the economic uncertainties, we sold approximately 24,800 acres of principally pre-merchantable, non-strategic timberland in southwest Arkansas for approximately $43.3 million in early January 2009. We expect continued weakness from our Wood Products business well into 2009, but we are moving aggressively to minimize the losses,” concluded Mr. Covey.
