Business Overview

We are a North American diversified wood products company which produces lumber (SPF and SYP), panels (plywood, MDF and LVL), pulp (NBSK and BCTMP), newsprint, wood chips and energy. We hold rights to timber resources that are sufficient to supply a significant amount of the fibre required by our Canadian operations and have long-term agreements for the supply of a considerable amount of the fibre required by our United States operations. We carry on our operations through subsidiaries and joint operations in British Columbia, Alberta and the southern United States. Our operations located in western Canada manufacture all of the products described above except SYP lumber. Our sawmills located in the southern U.S. produce SYP lumber and wood chips.

The annual production capacities of our wholly-owned facilities and our share of the capacities of our 50%-owned operations are as follows:

Lumber (MMfbm)
SPF	4,100

Corporate Strategy

Our goal at West Fraser is to generate strong financial results through the business cycle, relying on our committed work force, the quality of our assets and our well-established corporate culture. This culture emphasizes cost control in all aspects of the business and internal and external competitiveness. In our approach to employee relations, we emphasize employee involvement and favour internal promotions whenever possible.

We are a diversified producer of wood products with access to extensive timber resources. Our Canadian lumber, plywood, LVL and veneer operations are directly or indirectly the primary source of raw material for our pulp & paper and MDF operations.

Acquisitions and expansions are considered with a view to extending our existing business lines, particularly in lumber operations, and to product and geographic diversification. Our earnings over the business cycle have enabled us to make significant and ongoing capital investments in our facilities with the goal of achieving, maintaining or improving an overall low-cost position.

We are committed to operating in a financially conservative and prudent manner. The North American wood products industry is cyclical and periodically faces very difficult market conditions and serious challenges. During such cyclical downturns, we focus on financial discipline, including reduction or deferral of non-essential capital expenditures. As market conditions improve we will typically undertake an expanded capital investment program in order to catch up on expenditures reduced or deferred during the downturn. We believe that maintaining a strong balance sheet provides the ability to react to growth opportunities and is a key tool in managing our operations through a business cycle.
