NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)

FOR THE QUARTER ENDED MARCH 31, 2018 AND 2017

NOTE 1: BASIS OF PRESENTATION

We are a corporation that has elected to be taxed as a real estate investment trust (REIT). We expect to derive most of our REIT income from investments in timberlands, including the sale of standing timber. As a REIT, we generally are not subject to federal corporate level income taxes on REIT taxable income that is distributed to shareholders. We are required to pay corporate income taxes on earnings of our taxable REIT subsidiaries (TRSs), which includes our Wood Products segment and portions of our Timberlands and Real Estate, Energy and Natural Resources (Real Estate & ENR) segments.

Our consolidated financial statements provide an overall view of our results of operations and financial condition. They include our accounts and the accounts of entities we control, including:


•	majority-owned domestic and foreign subsidiaries and


•	variable interest entities in which we are the primary beneficiary.

They do not include our intercompany transactions and accounts, which are eliminated.

We account for investments in and advances to unconsolidated equity affiliates using the equity method, with taxes provided on undistributed earnings. This means that we record earnings and accrue taxes in the period earnings are recognized by our unconsolidated equity affiliates.

Throughout these Notes to Consolidated Financial Statements, unless specified otherwise, references to “Weyerhaeuser,” “we,” “the company” and “our” refer to the consolidated company.

The accompanying unaudited Consolidated Financial Statements reflect all adjustments that are, in the opinion of management, necessary for a fair presentation of our financial position, results of operations and cash flows for the interim periods presented. Except as otherwise disclosed in these Notes to Consolidated Financial Statements, such adjustments are of a normal, recurring nature. The Consolidated Financial Statements have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission pertaining to interim financial statements. Certain information and footnote disclosures normally included in our annual Consolidated Financial Statements have been condensed or omitted. These quarterly Consolidated Financial Statements should be read in conjunction with the Consolidated Financial Statements and Management’s Discussion and Analysis of Financial Condition and Results of Operations included in our Annual Report on Form 10-K for the year ended December 31, 2017 . Results of operations for interim periods should not necessarily be regarded as indicative of the results that may be expected for the full year.

NEW ACCOUNTING PRONOUNCEMENTS

Leases

In February 2016, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2016-02, which requires lessees to recognize assets and liabilities for the rights and obligations created by those leases and requires leases to be recognized on the balance sheet. The new guidance is effective for fiscal years beginning after December 15, 2018, and early adoption is permitted. We expect to adopt on January 1, 2019. We are still evaluating certain aspects of the revised guidance and subsequent revisions either made or being contemplated by the FASB, including application of the available practical expedients. We expect the adoption to result in the recognition of the present value of the future commitments on operating leases on our Consolidated Balance Sheet .

Reclassification of Certain Amounts from Accumulated Other Comprehensive Loss

In February 2018, the FASB issued ASU 2018-02, which allows for the reclassification of certain income tax effects related to the Tax Cuts and Jobs Act (the "Tax Act") between “Accumulated other comprehensive loss” and “Retained earnings.” This ASU provides that adjustments to deferred tax liabilities and assets related to a change in tax laws be included in “Income from continuing operations”, even in situations where the related items were originally recognized in “Other comprehensive income.” The amendments in this ASU are effective for all entities for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years, with early adoption permitted. Adoption of this ASU is to be applied either in the period of adoption or retrospectively to each period in which the effect of the change in the tax laws was recognized. We adopted this ASU during first quarter 2018 using the period of adoption method, which resulted in a reclassification of $253 million from "Accumulated other comprehensive loss" to "Retained earnings" on our Consolidated Balance Sheet due to changes in federal statutory and effective state rates. In general, tax effects unrelated to the Tax Cuts and Jobs Act are released from accumulated other comprehensive loss using the portfolio approach.

In January 2016, the FASB issued ASU No. 2016-01, which updates certain aspects of recognition, measurement, presentation and disclosure of financial instruments. We adopted ASU 2016-01 in first quarter 2018, which resulted in a reclassification of accumulated unrealized gains on available-for-sale securities of $9 million from "Accumulated other comprehensive loss" to "Retained earnings" on our Consolidated Balance Sheet .

NOTE 2: BUSINESS SEGMENTS

Reportable business segments are determined based on the company’s "management approach," as defined by FASB ASC 280, “Segment Reporting.” The management approach is based on the way the chief operating decision maker organizes the segments within a company for making decisions about resources to be allocated and assessing their performance.

We are principally engaged in growing and harvesting timber; manufacturing, distributing, and selling products made from trees; maximizing the value of every acre we own through the sale of higher and better use (HBU) properties; and monetizing reserves of minerals, oil, gas, coal, and other natural resources on our timberlands. The following is a brief description of each of our reportable business segments and activities:


•	Timberlands – which includes logs, timber and leased recreational access;


•	Real Estate & ENR – which includes sales of timberlands; rights to explore for and extract hard minerals, oil and gas production and coal; and equity interests in our Real Estate Development Ventures; and


•	Wood Products – which includes softwood lumber, engineered wood products, structural panels, medium density fiberboard and building materials distribution.

A reconciliation of our business segment information to the respective information in the Consolidated Statement of Operations is as follows:



	QUARTER ENDED
DOLLAR AMOUNTS IN MILLIONS	MARCH 2018			MARCH 2017

Net earnings	$	269		$	157


(1)	The Real Estate & ENR segment includes the equity earnings from investments in and advances to our Real Estate Development Ventures, which are accounted for under the equity method.


(2)	Unallocated items are gains or charges not related to, or allocated to, an individual operating segment. They include a portion of items such as: share-based compensation expenses, pension and postretirement costs, foreign exchange transaction gains and losses and the elimination of intersegment profit in inventory and LIFO.

NOTE 3: REVENUE

A majority of our revenue is derived from sales of delivered logs and manufactured wood products. We account for revenue in accordance with ASC Topic 606, Revenue from Contracts with Customers , which we adopted on January 1, 2018, using the cumulative effect method. The adoption of the new revenue recognition guidance did not materially impact our Consolidated Statement of Operations , Consolidated Balance Sheet , or Consolidated Statement of Cash Flows .

PERFORMANCE OBLIGATIONS

A performance obligation, as defined in ASC Topic 606, is a promise in a contract to transfer a distinct good or service to a customer. A contract's transaction price is allocated to each distinct performance obligation and recognized as revenue at the point in time, or over the period, in which the performance obligation is satisfied.

Performance obligations associated with delivered log sales are typically satisfied when the logs are delivered to our customers’ mills or delivered to an ocean vessel in the case of export sales. Performance obligations associated with the sale of wood products are typically satisfied when the products are shipped. Customers are generally invoiced shortly after logs are delivered or after wood products are shipped, with payment generally due within a month or less of the invoice date. ASC Topic 606 requires entities to consider significant financing components of contracts with customers, though allows for the use of a practical expedient when the period between satisfaction of a

performance obligation and payment receipt is one year or less. Given the nature of our revenue transactions, we have elected to utilize this practical expedient.

Performance obligations associated with real estate sales are generally met when placed into escrow and all conditions of closing have been satisfied.

CONTRACT ESTIMATES

Substantially all of the company’s performance obligations are satisfied as of a point in time. Therefore, there is little judgment in determining when control transfers for our business segments as described above.

The transaction price for log sales generally equals the amount billed to our customer for logs delivered during the accounting period. For the limited number of log sales subject to a long-term supply agreement, the transaction price is variable but is known at the time of billing. For wood products sales, the transaction price is generally the amount billed to the customer for the products shipped but may be reduced slightly for estimated cash discounts and rebates.

There are no significant contract estimates related to the real estate business.

CONTRACT BALANCES

In general, customers are billed and a receivable is recorded as we ship and/or deliver wood products and logs. We generally receive payment shortly after products have been received by our customers. Contract asset and liability balances are immaterial.

For real estate sales, the company receives the entire consideration in cash at closing.

On June 2, 2017, the Weyerhaeuser Board of Directors approved an equity purchase agreement with a consortium led by BTG Pactual's Timberland Investment Group (TIG), including other long-term investors, pursuant to which the Company agreed to sell, in exchange for $403 million in cash, all of its equity interest in the subsidiaries that collectively owned and operated its Uruguayan timberlands and manufacturing operations.

On September 1, 2017, we completed the sale of our Uruguay timberlands and manufacturing operations for approximately $403 million of cash proceeds. Due to the $147 million impairment of our Uruguayan operations recorded during second quarter 2017, no material gain or loss was recorded as a result of this sale.

The sale of our Uruguayan operations was not considered a strategic shift that had or will have a major effect on our operations or financial results, and therefore did not meet the requirements for presentation as discontinued operations.

NOTE 5: NET EARNINGS PER SHARE

Our basic and diluted earnings per share were:


•	$0.35 during first quarter 2018 and


•	$0.21 during first quarter 2017 .

Basic earnings per share is net earnings divided by the weighted average number of our outstanding common shares, including stock equivalent units where there is no circumstance under which those shares would not be issued. Diluted earnings per share is net earnings divided by the sum of the weighted average number of our outstanding common shares and the effect of our outstanding dilutive potential common shares:



	QUARTER ENDED
SHARES IN THOUSANDS	MARCH 2018	MARCH 2017
Weighted average common shares outstanding – basic	756,815	750,665
Dilutive potential common shares:
Stock options	1,682	2,981
Restricted stock units	569	547
Performance share units	396	554
Total effect of outstanding dilutive potential common shares	2,647	4,082
Weighted average common shares outstanding – dilutive	759,462	754,747

We use the treasury stock method to calculate the dilutive effect of our outstanding stock options, restricted stock units and performance share units. Share-based payment awards that are contingently issuable upon the achievement of specified performance or market conditions are included in our diluted earnings per share calculation in the period in which the conditions are satisfied.

Potential Shares Not Included in the Computation of Diluted Earnings per Share

The following shares were not included in the computation of diluted earnings per share because they were either antidilutive or the required performance or market conditions were not met. Some or all of these shares may be dilutive potential common shares in future periods.



	QUARTER ENDED
SHARES IN THOUSANDS	MARCH 2018	MARCH 2017
Stock options	1,301	1,432
Performance share units	744	568

NOTE 6: INVENTORIES

Inventories include raw materials, work-in-process, finished goods, and materials and supplies.



DOLLAR AMOUNTS IN MILLIONS	MARCH 31, 2018		DECEMBER 31, 2017
LIFO inventories:
Logs	$	19	$	17
Lumber, plywood, panels and fiberboard	76		66

Lumber, plywood, panels, fiberboard and engineered wood products	109		91
Other products	77		77
Materials and supplies	84		84
Total	$	445	$	383

LIFO – the last-in, first-out method – applies to major inventory products held at our U.S. locations. The FIFO – the first-in, first-out method – or moving average cost methods apply to the balance of our U.S. raw material and product inventories, all material and supply inventories and all

foreign inventories. If we used FIFO for all LIFO inventories, our stated inventories would have been higher by $70 million as of March 31, 2018 , and $70 million as of December 31, 2017 .

NOTE 7: SPECIAL-PURPOSE ENTITIES

From 2002 through 2004, we sold certain nonstrategic timberlands in five separate transactions. We are the primary beneficiary and consolidate the assets and liabilities of certain monetization and buyer-sponsored Special-purpose entities (SPEs) involved in these transactions. We have an equity interest in the monetization SPEs, but no ownership interest in the buyer-sponsored SPEs. The long-term notes of our monetization SPEs and the financial investments of our buyer-sponsored SPEs include $209 million and $253 million scheduled to mature in fourth quarter 2018 and first quarter 2019, respectively. We have classified the long-term notes scheduled to mature in fourth quarter 2018 as current liabilities and the financial investments scheduled to mature in first quarter 2019 as current receivables on our Consolidated Balance Sheet .

NOTE 8: PENSION AND OTHER POSTRETIREMENT BENEFIT PLANS

The components of net periodic benefit costs are:

For the periods presented, Service cost is included in "Cost of products sold," "Selling expenses," and "General and administrative expenses" and the remaining other items are included in "Non-operating pension and other postretirement benefit costs." Refer to the Consolidated Statement of Operations .

FAIR VALUE OF PENSION PLAN ASSETS AND OBLIGATIONS

We estimate the fair value of pension plan assets based upon the information available during the year-end reporting process. In some cases, primarily private equity funds, the information available consists of net asset values as of an interim date, cash flows between the interim date and the end of the year and market events. We update the year-end estimated fair value of pension plan assets to incorporate year-end net asset values reflected in financial statements received after we have filed our Annual Report on Form 10-K. We expect to complete the valuation of our pension plan assets during the second quarter 2018 .

EXPECTED CONTRIBUTIONS AND BENEFIT PAYMENTS

In 2018 we expect to:


•	be required to contribute approximately $23 million for our Canadian registered plan;


•	be required to contribute or make benefit payments for our Canadian nonregistered plans of $4 million ;


•	make benefit payments of $19 million for our U.S. nonqualified pension plans; and


•	make benefit payments of $19 million for our U.S. and Canadian other postretirement plans.

We do not anticipate being required to make a contribution to our U.S. qualified pension plans in 2018 .

NOTE 9: ACCRUED LIABILITIES

Accrued liabilities were comprised of the following:



DOLLAR AMOUNTS IN MILLIONS	MARCH 31, 2018		DECEMBER 31, 2017

NOTE 10:

LONG-TERM DEBT AND LINES OF CREDIT

During first quarter 2018, we paid our $62 million 7.00 percent debenture at maturity.

During March 2017, we entered into a new $1.5 billion five-year senior unsecured revolving credit facility that expires in March 2022 . This replaced a $1.0 billion senior unsecured revolving credit facility that was set to expire September 2018 . The entire amount is available to Weyerhaeuser Company. Interest on borrowings are at LIBOR plus a spread or at other interest rates mutually agreed upon between the borrower and the lending banks. As of March 31, 2018 , there were no borrowings outstanding.

NOTE 11: FAIR VALUE OF FINANCIAL INSTRUMENTS

The estimated fair values and carrying values of our long-term debt consisted of the following:



	MARCH 31, 2018				DECEMBER 31, 2017
DOLLAR AMOUNTS IN MILLIONS	CARRYING VALUE		FAIR VALUE (LEVEL 2)		CARRYING VALUE		FAIR VALUE (LEVEL 2)
Long-term debt (including current maturities) ⁽¹⁾ :
Fixed rate	$	5,704	$	6,568	$	5,768	$	6,823
Variable rate	224		225		224		225
Total debt	$	5,928	$	6,793	$	5,992	$	7,048

(1) Excludes nonrecourse debt held by our Variable Interest Entities (VIEs).

To estimate the fair value of fixed rate long-term debt, we used the following valuation approaches:


•	market approach – based on quoted market prices we received for the same types and issues of our debt; or


•	income approach – based on the discounted value of the future cash flows using market yields for the same type and comparable issues of debt.

We believe that our variable rate long-term debt instruments have net carrying values that approximate their fair values with only insignificant differences.

The inputs to these valuations are based on market data obtained from independent sources or information derived principally from observable market data. The difference between the fair value and the carrying value represents the theoretical net premium or discount we would pay or receive to retire all debt at the measurement date.

FAIR VALUE OF OTHER FINANCIAL INSTRUMENTS

We believe that our other financial instruments, including cash and cash equivalents, short-term investments, mutual fund investments held in grantor trusts, receivables, and payables, have net carrying values that approximate their fair values with only insignificant differences. This is primarily due to the short-term nature of these instruments and the allowance for doubtful accounts.

NOTE 12: LEGAL PROCEEDINGS, COMMITMENTS AND CONTINGENCIES

LEGAL PROCEEDINGS

We are party to various legal proceedings arising in the ordinary course of business. We are not currently a party to any legal proceeding that management believes could have a material adverse effect on our Consolidated Balance Sheet , Consolidated Statement of Operations , or Consolidated Statement of Cash Flows . See Note 18: Income Taxes for a discussion of a tax proceeding involving Plum Creek's 2008 U.S. federal income tax return.

ENVIRONMENTAL MATTERS

Site Remediation

Under the Comprehensive Environmental Response, Compensation and Liability Act (CERCLA) – commonly known as the Superfund – and similar state laws, we:


•	are a party to various proceedings related to the cleanup of hazardous waste sites and


•	have been notified that we may be a potentially responsible party related to the cleanup of other hazardous waste sites for which proceedings have not yet been initiated.

We have received notification from the Environmental Protection Agency (the EPA) and have acknowledged that we are a potentially responsible party in a portion of the Kalamazoo River Superfund site in southwest Michigan. Our involvement in the remediation site is based on our former ownership of the Plainwell, Michigan mill located within the remediation site. Several other companies also have been deemed potentially responsible parties as past or present owners or operators of facilities within the site, or as arrangers under CERCLA.

We are currently cooperating with other parties to jointly implement an administrative order issued by the EPA on April 14, 2016, with respect to a portion of the site comprising a stretch of the river approximately 1.7 miles long referred to as the Otsego Township Dam Area. We do not expect to incur material losses related to the implementation of this administrative order.

In 2010, the company, along with others, was named as a defendant by Georgia-Pacific Consumer Products LP, Fort James Corporation and Georgia-Pacific LLC in an action seeking contribution under CERCLA for remediation costs relating to a certain area within the site. On March 29, 2018, the U.S. District Court issued an opinion and order assigning the company responsibility for five percent of approximately $50 million in past costs incurred by the plaintiffs. The remaining ninety-five percent of this pool of past costs incurred was allocated to the plaintiffs and other defendants.

The opinion and order does not establish allocation for future remediation costs, and accordingly, we may incur additional costs in connection with future remediation tasks for other areas of the site. In connection with the opinion and order, we have updated our assessment of the company’s reasonably possible estimated liability associated with the site and have recorded a pretax charge of $28 million in the first quarter as "Other operating costs, net" on the Consolidated Statement of Operations .

As of March 31, 2018 , our total accrual for future estimated remediation costs on the active Superfund sites and other sites for which we are potentially responsible was approximately $72 million . These amounts are recorded in "Accrued liabilities" and "Other liabilities" on our Consolidated Balance Sheet .

Asset Retirement Obligations

We have obligations associated with the future retirement of tangible long-lived assets consisting primarily of reforestation obligations related to forest management licenses in Canada and obligations to close and cap landfills. As of March 31, 2018 , our accrued balance for these obligations was $34 million . These obligations are recorded in "Accrued liabilities" and "Other liabilities" on our Consolidated Balance Sheet . The accruals have not changed materially since the end of 2017 .

Some of our sites have materials containing asbestos. We have met our current legal obligation to identify and manage these materials. In situations where we cannot reasonably determine when materials containing asbestos might be removed from the sites, we have not recorded an accrual because the fair value of the obligation cannot be reasonably estimated.

PRODUCT REMEDIATION

In July 2017, the company announced it was implementing a solution to address concerns regarding our TJI® Joists with Flak Jacket® Protection product. The company has determined that an odor in certain newly constructed homes is related to a recent formula change to the Flak Jacket coating that included a formaldehyde-based resin. This issue is isolated to Flak Jacket product manufactured after December 1, 2016, and does not affect any of the company’s other products. We recorded pretax charges of $290 million to accrue for remediation costs in the year-to-date period ended December 31, 2017 . We received insurance recoveries of $20 million during the quarter ended March 31, 2018 . Refer to Note 16: Charges (Recoveries) for Product Remediation for further information.

NOTE 14: SHARE-BASED COMPENSATION

Share-based compensation activity in first quarter 2018 included the following:



SHARES IN THOUSANDS	Granted	Vested
Restricted Stock Units (RSUs)	673	576
Performance Share Units (PSUs)	344	110

A total of 1.5 million shares of common stock were issued as a result of RSU vestings, PSU vestings and stock option exercises.

RESTRICTED STOCK UNITS

The weighted average fair value of the RSUs granted in 2018 was $34.14 . The vesting provisions for RSUs granted in 2018 were as follows:


•	vest ratably over four years;


•	immediately vest in the event of death while employed or disability;


•	continue to vest upon retirement at an age of at least 62, but a portion of the grant is forfeited if retirement occurs before the one-year anniversary of the grant;


•	continue vesting for one year in the event of involuntary termination when the retirement criteria has not been met; and


•	will be entirely forfeited upon termination of employment in all other situations including early retirement prior to age 62.

PERFORMANCE SHARE UNITS

The weighted average grant date fair value of PSUs granted in 2018 was $35.49 .

The final number of shares granted in 2018 will range from 0 percent to 150 percent of each grant's target, depending upon actual company performance.

The ultimate number of PSUs earned is based on two measures:


•	our relative total shareholder return (TSR) ranking measured against the S&P 500 over a three year period and


•	our relative TSR ranking measured against an industry peer group of companies over a three year period.

The vesting provisions for PSUs granted in 2018 were as follows:


•	vest 100 percent on the third anniversary of the grant date if the individual remains employed by the company;


•	fully vest in the event the participant dies or becomes disabled while employed;


•	continue to vest upon retirement at an age of at least 62, but a portion of the grant is forfeited if retirement occurs before the one year anniversary of the grant;


•	continue vesting for one year in the event of involuntary termination when the retirement criteria has not been met and the employee has met the second anniversary of the grant date; and


•	will be entirely forfeited upon termination of employment in all other situations including early retirement prior to age 62.

NOTE 16: CHARGES (RECOVERIES) FOR PRODUCT REMEDIATION

In July 2017, we announced we were implementing a solution to address concerns regarding our TJI® Joists with Flak Jacket® Protection product. This issue was isolated to Flak Jacket product manufactured after December 1, 2016, and does not affect any of our other products. We estimate that approximately 2,400 homes were affected.

We recorded pretax charges of $290 million in the year-to-date period ended December 31, 2017, to accrue for expected costs associated with the remediation. During first quarter 2018, we received and recorded insurance recoveries of $20 million . The charges and recoveries are attributable to our Wood Products segment and were recorded in "Charges (recoveries) for product remediation," on the Consolidated Statement of Operations.

As of March 31, 2018 , $247 million has been paid out in relation to our remediation efforts. The remaining accrual of $43 million is recorded in "Accrued liabilities" on the Consolidated Balance Sheet . The company ultimately expects a significant portion of the total expense will be covered by insurance. As of March 31, 2018 , $20 million has been received and recorded for insurance recoveries.

NOTE 17: OTHER OPERATING COSTS, NET

Other operating costs, net:


•	includes both recurring and occasional income and expense items and


•	can fluctuate from year to year.

(1) "Other, net" includes environmental remediation charges. See Note 12: Legal Proceedings, Commitments, and Contingencies for more information.

NOTE 18: INCOME TAXES

As a REIT, we generally are not subject to federal corporate level income taxes on REIT taxable income that is distributed to shareholders. We are required to pay corporate income taxes on earnings of our wholly-owned TRSs, which includes our Wood Products segment and portions of our Timberlands and Real Estate & ENR segments' earnings.

The quarterly provision for income taxes is based on the current estimate of the annual effective tax rate. Our 2018 estimated annual effective tax rate for our TRSs is approximately 24 percent , which is higher than the U.S. domestic statutory federal tax rate primarily due to higher foreign tax rates applicable to foreign earnings and state income taxes.

TAX LEGISLATION

On December 22, 2017, H.R. 1, commonly known as the Tax Cuts and Jobs Act (the "Tax Act"), was enacted. The Tax Act contains significant changes to corporate taxation, including the reduction of the corporate tax rate from 35 percent to 21 percent . As a result of the reduction in the corporate tax rate, we revalued our deferred tax assets and liabilities and recorded a tax expense of $74 million during 2017, which reduced our net deferred tax asset. The deemed repatriation on deferred foreign income provisions does not impact our operations due to the fact that we have no foreign undistributed earnings.

The impact of the Tax Act provisions effective in 2018 is a reduction to our overall estimated annual effective tax rate primarily due to the reduced corporate tax rate.

During first quarter 2018, we adopted ASU 2018-02 which allows for the reclassification of certain income tax effects related to the Tax Act between accumulated other comprehensive income and retained earnings. Refer to Note 1: Basis of Presentation for further details on this ASU and the related impact on our financial statements.

ONGOING IRS MATTER

In connection with the merger with Plum Creek, we acquired equity interests in Southern Diversified Timber, LLC, a timberland joint venture (Timberland Venture) with an affiliate of Campbell Global LLC (TCG Member). On August 31, 2016, the Timberland Venture redeemed TCG Member's interest and became a fully consolidated, wholly-owned subsidiary of Weyerhaeuser.

We received a Notice of Final Partnership Administrative Adjustment (FPAA), dated July 20, 2016, from the Internal Revenue Service (IRS) in regard to Plum Creek's 2008 U.S. federal income tax treatment of the transaction forming the Timberland Venture. The IRS is asserting that the transfer of the timberlands to the Timberland Venture was a taxable transaction to Plum Creek at the time of the transfer rather than a nontaxable capital contribution. We have filed a petition in the U.S. Tax Court and will vigorously contest this adjustment.

In the event that we are unsuccessful in this tax litigation, we could be required to recognize and distribute gain to shareholders of approximately $600 million and pay built-in gains tax of approximately $100 million . We would also be required to pay interest on both of those amounts, which would be substantial. As much as 80 percent of any such gain distribution could be made with our common stock, and shareholders would be subject to tax on the distribution at the applicable capital gains tax rate. Alternatively, we could elect to retain the gain and pay corporate-level tax to minimize interest costs to the company.

Although the outcome of this process cannot be predicted with certainty, we are confident in our position based on U.S. tax law and believe we will be successful in defending it. Accordingly, no reserve has been recorded related to this matter.

Forward-looking statements speak only as of the date they are made, and we undertake no obligation to publicly update or revise any forward-looking statements, whether because of new information, future events, or otherwise.

RESULTS OF OPERATIONS

In reviewing our results of operations, it is important to understand these terms:


•	Sales realizations for Timberlands and Wood Products refer to net selling prices – this includes selling price plus freight, minus normal sales deductions. Real Estate transactions are presented at the contract sales price before commissions and closing costs, net of any credits.


•	Net contribution to earnings does not include interest expense and income taxes.

In the following discussion, unless otherwise noted, references to increases or decreases in income and expense items, sales realizations, shipment volumes, and net contributions to earnings are based on the quarter ended March 31, 2018 , compared to quarter ended March 31, 2017 .

ECONOMIC AND MARKET CONDITIONS AFFECTING OUR OPERATIONS

The demand for logs within our Timberlands segment is directly affected by production levels of domestic wood-based building products. The strength of the U.S. housing market strongly affects demand in our Wood Products segment, as does repair and remodeling activity. Our Timberlands segment, specifically the Western region, is also affected by export demand. Japanese housing starts are a key driver of export log demand in Japan.

In first quarter 2018, housing starts averaged 1.32 million total units on a seasonally adjusted annual basis according to the U.S. Census Bureau. Single family units accounted for 67 percent of total housing starts in first quarter. Multifamily starts rebounded from the decline posted in 2017. Single family starts are 6 percent higher on a year ago basis for the quarter. We continue to expect improving U.S. housing starts and anticipate a level of approximately 1.30 million units in 2018, an 8 percent increase compared to 2017. We attribute this continued improvement primarily to employment growth, improving consumer confidence and favorable mortgage rates, remain near historic lows.

According to the Joint Center for Housing of Harvard University, the Leading Indicator of Remodeling Activity, increased by 6.4 percent in 2017 and is expected to average 7.5 percent year over year for 2018.

U.S. wood product markets advanced in the first quarter of 2018, consistent with growth in homebuilding and remodeling segments, as described above. According to Forest Economic Advisors, LLC, North American lumber consumption is expected to grow at a 4 percent rate in 2018. Consistent with this expectation, demand for logs increased with wood products production within our Western region. This coupled with higher market prices in the first quarter drove higher realizations. In the South, log supplies kept pace with increased demand, leaving prices flat to slightly increased from fourth quarter 2017.

Log inventories in Chinese ports increased in the latter part of first quarter as reported by International Wood Markets China Bulletin. The increased inventory level is attributed to a slow start to the construction season due to the later occurrence of the Spring Festival and is expected to normalize over upcoming quarters. In Japan, wooden housing starts for January and February are down 1.7 percent from the same period last year.

We expect demand from China and Japan in 2018 to be similar to demand experienced in 2017.

Our Real Estate, Energy and Natural Resources segment is affected by the health of the U.S. economy and especially the U.S. housing sector of the economy. According to the Realtors Land Institute (RLI) of the National Association of Realtors, the dollar volume of rural properties, including timber, sold in 2017 grew 4 percent over 2016 sales while per acre prices were up 3 percent on average. Additionally, RLI is optimistic that these trends will continue in 2018.

Comparing First Quarter 2018 with First Quarter 2017

Net sales

Net sales increased $172 million – 10 percent – primarily attributable to the following factors:


•	Wood Products sales to unaffiliated customers increased $155 million – 13 percent – primarily due to increased sales realizations across the majority of product lines.


•	Timberlands sales to unaffiliated customers increased $19 million – 4 percent – primarily attributable to increased Western log sales realizations, partially offset by decreased international operations revenue from the sale of our Uruguayan operations in third quarter 2017.

Costs of products sold

Costs of products sold increased $76 million – 6 percent – primarily attributable to the following:


•	Wood Products segment costs of products sold increased $79 million – 9 percent – primarily due to increased log and fiber costs across all product lines in the West and Canada; and


•	Unallocated costs of product sold increased $18 million – 14 percent – primarily due to a $15 million increase in costs for elimination of intersegment profit in inventory and LIFO. Refer to Unallocated Items for further details.

Increased costs of products sold was partially offset by a $26 million increase – 13 percent – in Timberland intersegment sales which are eliminated upon consolidation. Refer to Timberlands for further details.

Operating income

Operating income increased $111 million – 38 percent – primarily attributable to:


•	increased consolidated gross margin of $96 million as described above;


•	increased product remediation insurance recoveries of $20 million received in first quarter of 2018; and


•	decreased general and administrative expenses and integration costs related to the merger of Plum Creek for $20 million.

Increased operating income was partially offset by $28 million increased environmental charges in first quarter 2018. Refer to Note 17: Other Operating Costs, Net , "Other, net" for further details.

Net earnings

Our Net earnings increased $112 million – 71 percent . This is attributable to increased operating income, as described above.

Comparing First Quarter 2018 with First Quarter 2017

Net sales to unaffiliated customers

Net sales to unaffiliated customers increased $19 million – 4 percent – primarily due to a $41 million increase in Western log sales attributable to a 26% increase in Western log prices, partially offset by a 6% decrease in Western delivered logs sales volumes.

This increase was partially offset by a $19 million decrease in sales from our Uruguay operations, which were divested in third quarter 2017.

Intersegment sales

Intersegment sales increased $26 million – 13 percent – primarily due to increases in Western log prices, consistent with third party sales discussed above.

Costs of products sold

Costs of products sold increased $7 million – 1 percent – primarily due to increased external sourcing costs to meet increased demand for export sales. The increase was partially offset by a decrease in our international cost of products sold due to the divestiture of our Uruguayan operations in third quarter 2017.

Operating income and Net contribution to earnings

Operating income and Net contribution to earnings increased $41 million – 28 percent – primarily attributable to increased gross margin discussed above.

The timing of real estate sales is a function of many factors, including the general state of the economy, demand in local real estate markets, the ability to obtain entitlements, the ability of buyers to obtain financing, the number of competing properties listed for sale, the seasonal nature of sales (particularly in the northern states), the plans of adjacent landowners, our expectation of future price appreciation, the timing of harvesting activities, and the availability of government and not-for-profit funding. In any period the average sales price per acre will vary based on the location and physical characteristics of parcels sold.

Comparing First Quarter 2018 with First Quarter 2017

Net sales

Net sales decreased $2 million – 4 percent – primarily attributable to a decrease in average price realized per acre due to mix of properties sold offset by an increase in acres sold.

Costs of products sold

Costs of products sold decreased $1 million – 5 percent – primarily attributable to mix of properties sold in first quarter 2018 as compared to first quarter 2017, as discussed above.

Comparing First Quarter 2018 with First Quarter 2017

Changes in Unallocated Items were primarily related to:


•	a $28 million increase in charges for "Other," due to environmental remediation charges recorded in first quarter 2018 (refer to Note 12: Legal Proceedings, Commitments and Contingencies );


•	a $15 million increase in charges for "Elimination of intersegment profit in inventory and LIFO" due to an increase in intercompany lumber and log inventories from first quarter 2017 to first quarter 2018; and


•	a $12 million decrease in charges related to our merger with Plum Creek compared to first quarter 2017 (refer to Note 15: Charges for Integration and Restructuring, Closures, and Asset Impairments for further details).

INTEREST EXPENSE

Our interest expense, net of capitalized interest incurred was:


•	$93 million for the first quarter 2018 and


•	$99 million for the first quarter 2017 .

Interest expense decreased by $6 million primarily due to the decreased average outstanding debt in first quarter 2018 compared to first quarter 2017.

INCOME TAXES

Our provision for income taxes was:


•	$30 million for the first quarter 2018 and


•	$24 million for the first quarter 2017 .

Our provision for income taxes is primarily driven by earnings generated by our TRSs. Overall performance results for our business segments can be found in Consolidated Results .

The Tax Act, enacted in December 2017, reduced the U.S. corporate tax rate from 35 percent to 21 percent. In first quarter 2018, our provision for income taxes was higher compared to first quarter 2017 due to increased earnings in our TRS. The tax impact of the increased earnings more than offset the benefit of the reduced U.S. corporate tax rate.

Refer to Note 18: Income Taxes for additional information.

LIQUIDITY AND CAPITAL RESOURCES

We are committed to maintaining an appropriate capital structure that enables us to protect the interests of our shareholders and lenders and maintain access to all major financial markets.

CASH FROM OPERATIONS

Consolidated net cash from operations was:


•	$136 million for first quarter 2018 ; and


•	$35 million for first quarter 2017 .

Comparing first quarter 2018 with first quarter 2017

Net cash from operations increased $101 million , primarily due to:


•	increased cash flows generated from our business segments, excluding working capital changes, of $103 million;


•	decreased cash paid for income taxes of $42 million ;


•	product remediation insurance recoveries received of $20 million in first quarter 2018;


•	decreased working capital used for accrued wages, salaries, and severance pay of $17 million; and


•	decreased cash paid for interest of $15 million; and

These increases were partially offset by a net increase in working capital from our business segments of $126 million.

CASH FROM INVESTING ACTIVITIES

Consolidated net cash used in investing activities was:


•	$76 million for first quarter 2018 ; and


•	$68 million for first quarter 2017 .

Comparing first quarter 2018 with first quarter 2017

Net cash used in investing activities increased $8 million , primarily due to:


•	a $6 million decrease in proceeds from sale of non-strategic assets; and


•	a $6 million increase in cash used for capital expenditures.

We expect our net capital expenditures for 2018 to be $420 million , which is comparable to 2017 capital spending. The amount we spend on capital expenditures could change.

CASH FROM FINANCING ACTIVITIES

Consolidated net cash used in financing activities was:


•	$286 million for first quarter 2018 and


•	$188 million for first quarter 2017 .

Comparing first quarter 2018 with first quarter 2017

Net cash used in financing activities increased $98 million primarily due to the following:


•	an increase of $62 million in cash used for payments of long-term debt; and


•	a decrease of $30 million in proceeds from exercises of stock options.

Lines of Credit

During March 2017, we entered into a new $1.5 billion five-year senior unsecured revolving credit facility that expires in March 2022 . This replaces a $1 billion senior unsecured revolving credit facility that was set to expire September 2018 . As of March 31, 2018 , there were no borrowings outstanding.

Refer to Note 10: Long-Term Debt and Lines of Credit for further information.

Long-term Debt

During first quarter 2018, we paid our $62 million 7.00 percent debenture at maturity.

Refer to Note 10: Long-Term Debt and Lines of Credit for further information.

Debt Covenants

As of March 31, 2018 , Weyerhaeuser Company was in compliance with its debt covenants. There have been no significant changes during first quarter 2018 to the debt covenants presented in our 2017 Annual Report on Form 10-K for our existing long-term debt instruments.

Option Exercises

We received cash proceeds from the exercise of stock options of:


•	$25 million in first quarter 2018 and


•	$55 million in first quarter 2017 .

Our average stock price was $35.29 and $32.53 for first quarter 2018 and first quarter 2017 , respectively.

Paying Dividends and Repurchasing Shares

We paid cash dividends on common shares of:


•	$242 million in first quarter 2018 and


•	$233 million in first quarter 2017 .

The increase in dividends paid is primarily due to an increase in our quarterly dividend from 31 cents per share to 32 cents per share in November 2017.

The 2016 Share Repurchase Authorization was approved in November 2015 by our Board of Directors and authorized management to repurchase up to $2.5 billion of outstanding shares. During first quarter 2018 , we did not repurchase any shares. As of March 31, 2018 , we had remaining authorization of $500 million for future share repurchases.

If a repurchase were to occur, we would record share repurchases upon the trade date as opposed to the settlement date when cash is disbursed. We would record a liability for repurchases that had not yet been settled. There were no unsettled repurchases as of March 31, 2018 .

PERFORMANCE MEASURES

We use Adjusted Earnings before Interest, Taxes, Depreciation, Depletion and Amortization (Adjusted EBITDA) as a key performance measure to evaluate the performance of the consolidated company and our business segments. This measure should not be considered in isolation from and is not intended to represent an alternative to our results reported in accordance with U.S. generally accepted accounting principles (U.S. GAAP). However, we believe Adjusted EBITDA provides meaningful supplemental information for investors about our operating performance, better facilitates period to period comparisons, and is widely used by analysts, lenders, rating agencies and other interested parties.

Our definition of Adjusted EBITDA may be different from similarly titled measures reported by other companies. Adjusted EBITDA, as we define it, is operating income adjusted for depreciation, depletion, amortization, basis of real estate sold, unallocated pension service costs and special items. Adjusted EBITDA excludes results from joint ventures.
