Use of Estimates The preparation of the financial statements requires management to make a number of estimates and assumptions that affect the reported amount of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the period.
The most significant estimates, as discussed within our Summary of Significant Accounting Policies, pertain to the critical assumptions utilized in testing real estate assets for impairment as well as in estimating the fair value of real estate assets when an impairment event has taken place.
Actual results could differ from those estimates.
(3) Significant Acquisitions and Dispositions Consolidation of Retail Joint Ventures Through March 31, 2009, we were a member in two retail real estate joint ventures with a retail developer.
Both entities were jointly controlled by us and our partner, through equal voting interests, and were accounted for as unconsolidated subsidiaries under the equity method.
As of April 1, 2009, we had made combined equity contributions of $37.9 million to the two entities and we also had combined outstanding principal and accrued interest of $173.0 million on advances to the two entities.
We advanced $2.0 million to the two entities, who then distributed the $2.0 million to our partner in exchange for the redemption of our partner’s membership interests, effective April 1, 2009, at which time we obtained 100% control of the voting interests of both entities.
We entered these transactions to gain control of these two entities because it will allow us to operate or dispose of the entities in a manner that best serves our capital needs.
In conjunction with the redemption of our partner’s membership interests, we entered a profits interest agreement that entitles our former partner to additional payments should the combined sale of the two acquired entities, as well as the sale of another retail real estate joint venture that we and our partner still jointly control, result in an aggregate profit.
Aggregate profit on the sale of these three projects will be calculated by using a formula defined in the profits interest agreement.
We have estimated that the fair value of the potential additional payment to our partner is insignificant.
A summary of the fair value of amounts recognized for each major class of assets and liabilities acquired is as follows (in thousands):
## Table 0 ##
The fair values recognized from the real estate and related assets acquired were primarily determined using the income approach.
The most significant assumptions in the fair value estimates were the discount rates and the exit capitalization rates.
The estimates of fair value were determined to have primarily relied upon Level 3 inputs.
Five-Year Summary of Wood Products Production
## Table 1 ##
HOW MUCH WE SELL Revenues of our Wood Products business segment come from sales to wood products dealers, do-it-yourself retailers, builders and industrial users.
We provide products and services to the residential construction market under the iLevel?brand.
In 2008, our net sales were $3.8 billion compared with $5.7 billion in 2007.
Five-Year Summary of Net Sales for Wood Products
## Table 2 ##
Five-Year Trend for Total Net Sales in Wood Products
Percentage of 2008 Net Sales in Wood Products
Wood Products Volume The volume of wood products sold in 2008 declined from 2007 primarily due to a significant decline in market demand, resulting from the downturn of the homebuilding and repair and remodel markets.
In response to these market conditions in 2007 and 2008, we sold or closed a number of facilities and curtailed production at several other mills.
The sales and closures include: ?Sales: – 2008 – seven U. S.  distribution centers; and – 2007 – two plywood facilities and 16 Canadian distribution centers.
?Closures: – 2008 – three lumber mills, four U. S.  distribution centers and two Canadian OSB mills that were curtailed in 2007; and – 2007 – two lumber mills, one engineered lumber mill, two U. S.  distribution centers, a plywood line and a veneer peeling operation.
?Indefinite curtailment: – 2008 – one Canadian OSB mill and one engineered lumber mill; and – 2007 – two Canadian OSB mills and two engineered lumber mills.
In December 2008, the board of directors approved an amendment to our bylaws to adopt a December 31 fiscal year-end, effective for the fiscal year-end 2008.
Prior to 2008, our fiscal year ended on the last Sunday of the calendar year.
As a result, the number of weeks in our fiscal year varied.
For the last three years: ?Fiscal year 2008 had 52 weeks and three days.
?Fiscal year 2007 had 52 weeks.
?Fiscal year 2006 had 53 weeks.
In reviewing our results of operations, it is important to understand these terms: ?Price realizations refer to net selling prices – this includes selling price plus freight minus normal sales deductions.
?Contribution to earnings refers to: – earnings before interest and income taxes for the Weyerhaeuser business segments and – earnings before income taxes for the Real Estate business segment.
Interest that previously was capitalized to Real Estate assets that are sold is included in cost of products sold and in contribution to earnings for the Real Estate segment.
CONSOLIDATED RESULTS Net sales and revenue and operating income numbers reported in our consolidated results do not include the activity of our discontinued operations: ?Containerboard, Packaging and Recycling operations (sold in August 2008); ?Australian operations (sold in July 2008); ?Trus Joist?Commercial division (held for sale as of December 2008); ?Fine Paper operations (divested in March 2007); ?Irish composite panel operations (sold in November 2006); and ?North American composite panel operations (sold in July 2006).
We report these activities and results as discontinued operations in our Consolidated Statement of Earnings.
However, we include the results of these operations in the segment discussions that follow.
See Note 3: Discontinued Operations and Assets Held For Sale in the Notes to Consolidated Financial Statements for more information about our discontinued operations.
