NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)

AS OF JUNE 30, 2013 AND DECEMBER 31, 2012 AND FOR THE SIX MONTH PERIODS ENDED JUNE 30, 2013 AND 2012

Nature of Business:

General — Longview Timber LLC (or the “Company”) is a limited liability company engaged in the ownership and management of timberlands in Oregon and Washington, which principally produce logs for sale from its timberlands. All of the timber facilities are located in the United States (U.S.). Longview Timber LLC owns and manages approximately 644,900 acres of timberlands in the U.S. Pacific Northwest composed primarily of softwoods. Longview Timber LLC is owned 98.89% by Longview Timber Holdings LLC, its initial member and 1.11% by Longview GP LLC, its special member.

Longview Timber LLC is the owner of Longview Fibre Company which is a real estate investment trust (“REIT”). A REIT is a company that derives most of its income from investments in real estate, which includes timberlands. A corporation that qualifies as a REIT generally will not be subject to corporate taxes on income and gains from investments in real estate to the extent that it distributes such income and gains to its shareholders. The principal REIT qualifying investment of Longview Timber LLC consists of timberlands. As a REIT, Longview Fibre Company will be required to pay federal corporate income tax on earnings from non-real estate investments and on earnings from real estate investments that are not distributed to its shareholders.

Basis of Presentation — The consolidated financial statements presented herein are those of Longview Timber LLC and its subsidiaries, and are derived from the records of such entities after the elimination of intercompany balances and transactions. Reference to Longview Timber LLC or the Company also includes, as applicable, reference directly or indirectly to any of its subsidiaries including –Longview Fibre Company; Longview Timberlands LLC; and Longview Timber, Corp. The consolidated financial statements have been prepared by Longview Timber LLC without audit and are subject to year-end adjustment, in accordance with accounting principles generally accepted in the United States of America, except that certain information and footnote disclosures made in the latest year-end financial statements may have been condensed or omitted for the interim statements. Certain costs are estimated for the full year and allocated into interim periods based on estimates of operating time expired, benefit received, or activity associated with the interim period. The consolidated financial statements reflect all adjustments which are, in the opinion of management, necessary for a fair presentation of the results for the interim periods. The year-end balance sheet data was derived from audited financial statements, but does not include all disclosures required by accounting principles generally accepted in the United States of America.

Cash and Cash Equivalents — Cash and cash equivalents consist of cash and highly liquid investments purchased with maturities of three months or less at date of acquisition. Cash equivalents held by Longview Timber LLC are considered Level 2 assets as defined by fair value accounting guidance, as the fair value of such assets are based on inputs, other than quoted prices in active markets which are observable either directly or indirectly.

- 6 -

Accounts Receivable and Allowance for Doubtful Accounts — Accounts receivable are comprised mainly of trade accounts receivable primarily from the sale of products on credit. Credit is extended to customers based on an evaluation of their financial condition. The adequacy of the allowance for doubtful accounts is based on historical experience and past due status, in addition to management’s evaluation of material customer accounts including ability to pay, bankruptcy, payment history, and other factors.

Bad debt expense associated with uncollectible accounts was zero for the six month periods ended June 30, 2013 and June 30, 2012, respectively. The Company recorded no allowance for doubtful accounts as of June 30, 2013 and December 31, 2012, respectively.

Inventories — Inventories are stated at the lower of cost or market. If actual demand or market conditions are less favorable than those projected by management, inventory write-downs may be required. Cost is determined on a first-in, first-out basis except for supplies, which are stated using the average cost method. Seedlings are reclassified to timber, timberlands, and logging roads when used in the reforestation process.

Timber, Timberlands, and Logging Roads; Timber Depletion, Logging Roads Amortization and Bridge Amortization — Timber, timberlands and logging roads are stated at cost, net of accumulated depletion and amortization. Timber, upon reaching the age of 35 years, is considered merchantable and available for harvesting, with all timber younger than 35 years of age being classified as premerchantable. Timber is tracked on a county-by-county basis whereby capital costs and estimated recoverable timber volumes are accumulated in the county in which the related timber is located. Expenditures for reforestation, including costs such as site preparation, tree planting, fertilization and herbicide application for the two years after planting, are capitalized and depleted as timber is harvested. After two years of age, plantation maintenance and tree farm management costs, consisting of recurring items necessary to the ownership and administration of the timber and timberlands, are recorded as a current period expense. Impairment is reviewed annually, or whenever events or circumstances indicate that the carrying value of an asset or group of assets may not be recovered pursuant to Accounting Standards Codification (“ASC”) 360, Property, Plant and Equipment.(“ASC 360”). Management evaluates whether or not the undiscounted future cash flows generated by the asset, or comparable sales will exceed its carrying value. If estimated future cash flows indicate the carrying value of an asset or group of assets may not be recoverable, impairment exists, and the asset’s net book value is written down to its estimated fair value.

Provision for depletion of merchantable timber represents a charge per unit of production (“depletion rate”) applied to actual harvest volumes. Management has applied four depletion rates for its timberlands which are based on geographical regions in Oregon and Washington. The depletion rates are validated to a computer growth index model that tracks the timber volumes through the growth cycle and is based upon actual growth rates from permanent timber growth plots throughout the U.S. Pacific Northwest. The depletion rates are adjusted annually for timber maturity, estimated growth, and actual harvest volumes or when there is a significant acquisition or disposition.

Direct costs associated with the building of primary and major secondary access logging roads are capitalized and amortized on the straight-line basis over estimated useful lives ranging from 3 to 15 years. Bridges are amortized over an estimated useful life of 35 years. Costs incurred for logging roads that serve short-term harvest needs are expensed as incurred. Costs for road base construction of mainline roads, such as clearing and grading, are not amortized and remain a capitalized cost until disposition as they provide permanent value to the timberlands.

- 7 -

Timberland acquisitions are recorded originally at fair value and any gain or loss on timberland dispositions are recorded at the time of sale.

Property, Plant and Equipment, and Depreciation — Property, plant and equipment are recorded at cost, net of accumulated depreciation. Plant and equipment, include those additions and improvements that add to production capacity or extend useful life. Impairment, in accordance with ASC 360, is reviewed annually, or whenever events or circumstances indicate that the carrying value of an asset or group of assets may not be recovered. Impairment evaluates whether or not the undiscounted future cash flows generated by an asset will exceed its carrying value. If estimated future cash flows indicate the carrying value of an asset or group of assets may not be recoverable, impairment exists, and the asset’s net book value is written down to its estimated fair value. When properties are sold or otherwise disposed of, the cost and the related accumulated depreciation are removed from the respective accounts, and the resulting profit or loss is recorded in operations. The costs of maintenance and repairs are charged to operations when incurred.

Depreciation is computed on a straight-line basis over the estimated useful lives of the assets. The estimated useful lives of assets range from 4 to 10 years for machinery and equipment.

Revenue Recognition — Revenues are recognized from sales to customers when title and risk of loss pass to the customer and when the sales price is fixed or determinable. For all sales, ownership transfers upon receipt by customers of logs (“FOB-destination”) or upon shipment to customers of logs (“FOB-shipping point”).

Use of Estimates — The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results may differ from those estimates.

New Accounting Pronouncements — In February 2013, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2013-02, which amends FASB Accounting Standards Codification (“ASC”) Topic 220, “Comprehensive Income.” The amendments in this guidance require an entity to provide information about the amounts reclassified out of accumulated other comprehensive income by component. In addition, an entity is required to present, either on the face of the financial statements or in the notes, significant amounts reclassified out of AOCI by the respective line items of net income if the amount reclassified is required under GAAP to be reclassified to net income in its entirety in the same reporting period. For other amounts that are not required under GAAP to be reclassified in their entirety to net income, an entity is required to cross-reference to other disclosures required by GAAP that provide additional detail about those amounts. This guidance is effective prospectively for interim and annual reporting periods beginning after December 15, 2012. Longview Timber LLC has evaluated the impact of adopting this guidance on its financial statements and disclosures included within Notes to Consolidated Financial Statements and has determined the standard had no impact.

Longview Timber LLC is taxable as a partnership and is generally not subject to income taxes on its stand-alone taxable income from operations and investments; such taxes are the responsibility of the individual members. During the six month periods ended June 30, 2013 and 2012, Longview Timber LLC made cash distributions to its members of $42.8 million and $30.0 million, respectively.

Generally, in any year which Longview Timber LLC’s subsidiary Longview Fibre Company qualifies as a REIT under the Internal Revenue Code (“IRC”), it is not subject to federal income tax on that portion of its income that it distributes to its shareholders. During the six month periods ended June 30, 2013 and 2012, Longview Fibre Company made cash distributions to its shareholders of $43.3 million and $29.7 million, respectively. Such distributions in the six month periods ended June 30, 2013 and 2012 have been designated as $26.0 and $16.4 million of capital gain distributions and $17.3 and $13.3 million of return of capital, respectively. None of the amounts distributed were ordinary dividends as defined by the IRC. In addition, Longview Fibre Company anticipates it will distribute all of the net capital gains for 2013. All of the net capital gains for 2012 were distributed as noted above.

With limited exceptions, Longview Fibre Company will; however, be subject to corporate tax on built-in gains (the excess of fair market value over tax basis of property at January 1, 2006, the date of REIT election) on taxable sales of such built-in gain property during the ten years following REIT conversion. Built-in gain tax from the sale of REIT property may be off-set by utilization of pre-REIT net operating losses or by reinvesting sale proceeds in similar property that qualifies as like-kind under requirements of the IRC.

In order to maintain compliance with REIT tax rules, Longview Fibre Company utilizes a taxable REIT subsidiary (“TRS”) for various non-REIT qualifying activities including the harvest and sale of logs. The TRS is consolidated by Longview Timber LLC.

Accordingly, the provision for corporate income taxes relates to deferred tax on certain property sales (from utilization of pre-REIT net operating losses) and on income from TRS operations.

The provision for income taxes for the six month periods ended June 30, 2013 and 2012, consisted of the following (dollars in thousands):

An analysis of the income tax provision for the six month periods ended June 30, 2013 and 2012, is as follows (dollars in thousands):

The tax effect of temporary differences giving rise to deferred tax assets at June 30, 2013 and December 31, 2012, is as follows (dollars in thousands):

The tax years 2009 through 2012 are subject to examination by the tax authorities. With few exceptions, Longview Timber LLC is no longer subject to U.S. federal, state, local examinations by tax authorities for years before 2009.

Uncertain Tax Positions — Income tax positions must meet a more likely than not recognition threshold at the effective date to be recognized upon the adoption of ASC 740, Income Taxes (“ASC 740”), and in subsequent periods. ASC 740 also provides guidance on measurement, derecognition, classification, interest and penalties, accounting in interim periods, disclosure and transition.

Longview Timber LLC recognizes tax liabilities in accordance with ASC 740 and adjusts these liabilities when our judgment changes as a result of the evaluation of new information not previously available. Due to the complexity of some of these uncertainties, the ultimate resolution may result in a payment that is materially different from the current estimate of the tax liabilities. These differences will be reflected as increases or decreases to income tax expense in the period in which they are determined. Longview Timber LLC records the related interest and penalties on these within income tax expense as well.

Longview Timber LLC does not have any reserves for uncertain tax positions as of June 30, 2013 or December 31, 2012.

Accrued liabilities at June 30, 2013 and December 31, 2012, consisted of the following (dollars in thousands):

Debt is provided by Metropolitan Life Insurance Company and a syndicate of lenders (the “Lenders”). The total debt on the balance sheet is $1,070 million as of June 30, 2013 and December 31, 2012. The debt is collateralized with the timber, timberlands, and logging roads.

Total debt consists of the following tranches:

The portion of the debt ($453.3 million), which originally matured on April 3, 2013, was replaced through a new agreement with the Lenders with variable rate debt on June 18, 2013. This debt matures on April 3, 2018. The variable rates are calculated quarterly as the three-month LIBOR interest rate, which is a predetermined number of days prior to the interest payment, plus a set amount of basis points as defined in the related debt agreement on the 15^th day of the month starting the calendar quarter. The LIBOR rate used for the most recent interest payment was 2.273%. The related cash interest expense recorded was $26.6 million and $26.5 million during the six month periods ended June 30, 2013, and 2012, respectively.

Longview Timber LLC’s debt agreements contain customary covenants and default provisions, including a covenant not to exceed a specified debt-to-value ratio of 0.60. It also includes a restriction on distributions if the cash flow coverage ratio is less than 1.25 on a rolling eight-quarter basis. See Note 15 related to distribution amounts to shareholders. As of June 30, 2013, Longview Timber LLC was in compliance with all financial and nonfinancial covenants of its debt agreements.

Longview Timber LLC has no participation in any pension, retiree medical, or health care insurance plans. Longview Timber LLC has a matching defined contribution 401k plan. The amount contributed and expensed to the 401k plan was $0.2 million for the six month periods ended June 30, 2013 and 2012, respectively.

A summary of the significant related party transactions is provided below:

- 13 -

In 2008, Longview Timber LLC held a bridge loan with three lenders — Merrill Lynch USA, Royal Bank of Canada and The Bank of Nova Scotia (the “Bridge Loan”). On April 3, 2008, the Bridge Loan was refinanced with a combination of long-term debt and a short-term related party bridge loan. Longview Timber LLC used fixed interest rate swap agreements (“swaps”) to manage changes in cash flow as a result of changes in interest rate movements on certain of the variable rate debt formerly held under the Bridge Loan. Longview Timber LLC had designated these swaps as cash flow hedges. To receive hedge accounting treatment, all of the swaps were formally documented at the inception of each hedge and the hedges were determined to be highly effective at swap inception and throughout the term of the Bridge Loan. As the swaps were highly effective, the change in fair value, net of income taxes, was recorded in other comprehensive income or loss, except for the ineffective portion of the fair value change, which was recognized in operations. If the swaps had not been determined to be highly effective, Longview Timber LLC would have recorded the change in fair value in operations.

Longview Timber LLC terminated the swaps in connection with the re-financing of the Bridge Loan in 2008 with $53.5 million being paid to the counterparties.

The previously recognized losses related to these swaps, which are recorded in accumulated other comprehensive loss, will be recorded into operations in the same periods that the hedged transaction affects operations. The amounts are recorded within interest expense and the expense related to this was $2.2 million for the six month periods ended June 30, 2013 and 2012, respectively.

Noncontrolling interest represents preferred stock interest in the equity of Longview Fibre Company, which was recorded as noncontrolling interest within equity in the amount of $(9) thousand and $(1) thousand as of June 30, 2013 and December 31 2012, respectively.

On May 10, 2007, Longview Fibre Company issued 125 shares of non-voting preferred stock with par value of $1 thousand to 125 individual stockholders. Preferred stock has a par value of $1 thousand per share, with liquidation preference of the same amount. The dividend rate for preferred shares is 12.5%. The shares were callable with a premium of 5% as of December 31, 2012. The premium reduced, net of issuance costs, 5% per annum such that there will be no premium after December 31, 2012.

Dividends — Longview Fibre Company declared and paid dividends in the amount of $8 thousand for the six month periods ended June 30, 2013 and 2012, respectively.

Longview Timber LP entered into a limited partnership as of April 20, 2007, with Longview GP LLC as the general partner and Longview Timber Holdings LLC as the limited partner. On October 9, 2008, Longview Timber LP converted to a limited liability company, Longview Timber LLC, pursuant to and in accordance with the Delaware Limited Liability Company Act upon which Longview GP LLC became the special member and Longview Timber Holdings LLC became the initial member. As of June 30, 2013 and December 31, 2012, the ownership interest is 1.11% or 15,295 units as to the special member and 98.89% or 1,364,458 units as to the initial member.

Allocation and Distribution to Members — Profit and loss shall be allocated to the members in proportion to their interest percentage for the period. All cash derived from operations of the limited liability company, but less cash used to pay current operating expenses and to pay or establish reasonable reserves as determined by the special member, shall be distributed to the members in proportion to their interest percentage.

Longview Timber LLC made distributions of $42.3 million and $29.7 million to the initial member and $0.5 million and $0.3 million to the special member for the six month periods ended June 30, 2013 and 2012, respectively.

Legal Matters and Litigation — Longview Timber LLC is subject to legal proceedings and claims that arise in the ordinary course of the business. Although there can be no assurance as to the disposition of these matters and the proceedings, it is the opinion of Longview Timber LLC’s management, based upon the information available at this time, that the expected outcome of these matters, individually or in aggregate, will not have a material effect on the ongoing results of operations, the financial condition of the business, or cash flows.

Log Sales Agreement — Longview Timber LLC has two log sale agreements with Hampton Tree Farms, Inc., a subsidiary of Hampton Affiliates, under which Longview Timber LLC must provide a combined 50 million board feet of logs per year at the applicable market rate. One agreement, which supplies 20 million board feet annually, runs through October 2023 and may be extended for an additional five year term unless it is terminated by either party. The other agreement, which supplies 30 million board feet annually, runs through December 2016.

Longview Timber LLC’s debt is carried at cost in the consolidated financial statements. The fair value of fixed-rate debt has been estimated based on the present value of future cash flows discounted at rates consistent with comparable maturities with similar credit risks. The carrying amount of variable-rate debt approximates fair value because of the frequent re-pricing of these instruments at market rates. The following table presents the carrying amount and estimated fair value of Longview Timber LLC’s fixed-rate and variable-rate debt (in thousands):

Longview Timber LLC had the following concentrations of Sales and Accounts Receivable as of and for the six month periods ended June 30, 2013 and 2012:

The Company maintains cash balances, which, at times, exceed the federally insured amount of $250,000. The Company has not experienced any losses from these accounts and believes it is not exposed to significant credit risk.

Longview Timber LLC has evaluated subsequent events through July 26, 2013 which is the date the consolidated financial statements were available to be issued. On June 14, 2013, Weyerhaeuser Columbia Holding Co. LLC entered into an agreement to acquire 100% of the members’ units of Longview Timber LLC. The sales price was $2,650 million adjusted for normal working capital as defined in the agreement, with closing occurring on July 23, 2013.
