GENERAL DEVELOPMENT OF THE BUSINESS

Changes in the Business 2015-2018

Inverness Project

In October 2017, construction was substantially completed and production commenced at the Company’s new Inverness, Scotland OSB line, with no disruption to existing production capacity. The Company had previously announced on January 28, 2016 a US $135 million investment to modernize and expand the mill, including moving the unused second press from its Grande Prairie, Alberta mill. The reinvested mill has a stated capacity of 720 million square feet (3/8-inch basis), an increase of 325 million square feet over the mill’s existing capacity.

Normal Course Issuer Bid

On October 27, 2017, the Company announced that it had received approval from the Toronto Stock Exchange (TSX) to renew its normal course issuer bid in accordance with TSX rules. Under the bid, the Company may purchase up to 5,142,773 of its Common Shares, representing 10% of the Company's public float of 51,427,739 as of October 20, 2017 (a total of 86,387,210 Common Shares were issued and outstanding). Purchases under the bid will terminate on the earlier of November 2, 2018,

Norbord Inc. 2018 Annual Information Form Page 4

the date Norbord completes its purchases pursuant to the notice of intention to make a normal course issuer bid filed with the TSX or the date of notice by Norbord of termination of the bid. As of the date of this AIF, the Company had not made any purchases under this bid or the previous bid which expired on November 2, 2017. Shareholders may obtain a copy of the notice filed with the TSX authorizing the bid without charge, by contacting the Company at (416) 365-0705 or info@norbord.com.

In-kind Distribution

On October 13, 2017, Brookfield completed an in-kind distribution (the Distribution) of an aggregate of 7.1 million Common Shares of Norbord to investors in certain of its funds. Upon completion of the Distribution, Brookfield owned and controlled approximately 40% of Norbord Common Shares.

Huguley, Alabama

In October 2017, Norbord's Huguley, Alabama mill, which had been curtailed since 2009, restarted production.

Secondary Offering

On August 2, 2017, Brookfield and the Company entered into an agreement with a syndicate of underwriters to complete a bought deal secondary offering of Norbord’s Common Shares (the Offering). Under the Offering, the syndicate agreed to purchase 3.6 million Common Shares from Brookfield at a purchase price of C $42.35 per Common Share. On August 9, 2017, upon the completion of the Offering, Brookfield owned, directly and indirectly, approximately 49% of Norbord's Common Shares (subsequently reduced to 40% following the Distribution described above). Norbord did not receive any proceeds from the Offering.

British Columbia Wildfires

On July 10, 2017, Norbord announced that its mill in 100 Mile House, British Columbia had temporarily suspended production in order to comply with evacuation orders due to wild fires burning nearby in the region.  The mill resumed operation approximately two weeks later. The curtailment did not materially impact Norbord's results.

Chambord Wood Allocation

On June 26, 2017, Norbord announced that the Quebec Minister of Forests, Wildlife and Parks had granted the Company a wood allocation for its curtailed Chambord, Quebec OSB mill that will take effect April 1, 2018. Norbord acquired the Chambord OSB mill in the fall of 2016 following an asset exchange (see Quebec mill exchange below). The Chambord mill was built in the 1980s and has a stated capacity of 470 million square feet (3/8-inch basis). Production from the mill was indefinitely curtailed in 2008 by its previous owner.

Repayment of Debt Securities

On February 15, 2017, the Company permanently repaid its $200 million senior secured notes upon maturity using cash on hand and temporary drawings on the accounts receivable securitization program which were repaid in the second quarter of 2017.

Quebec Mill Exchange

On October 28, 2016 the Company announced that it had reached an agreement with Louisiana-Pacific Corporation (LP) to swap ownership of its mill in Val-d’Or for LP’s mill in Chambord, Quebec. Production at both mills has been curtailed for a number of years. The non-monetary asset exchange transaction closed November 3, 2016. The Chambord mill has a stated capacity of 470 million square feet (3/8-inch basis) and the Val-d’Or mill has a stated capacity of 340 million square feet (3/8-inch basis).

High Level Fire

On May 4, 2016, a fire started in the woodyard of the High Level, Alberta mill. Production was halted immediately while the fire was brought under control. The mill has an annual production capacity of 860 million square feet (3/8-inch basis) and has been ramping up toward full production since resuming operations in late 2013. The fire destroyed a portion of the mill’s log inventory. The mill returned to production approximately three weeks later. The claim was closed in 2017 and the Company recognized an insurance recovery of $18 million for the reimbursement of the lost log inventory, costs of fighting the fire, site restoration and business interruption.

Norbord Inc. 2018 Annual Information Form Page 5

NYSE Listing

On February 16, 2016, the Company announced that its shares had been authorized for listing on the New York Stock Exchange (NYSE). The shares began trading on the NYSE on February 19, 2016 under the symbol “OSB”. Concurrent with the NYSE listing, the Company changed its ticker symbol on the TSX to “OSB”.

Bank Line Amendments

In April 2016, the Company amended its committed revolving bank lines to increase the tangible net worth covenant to $500 million and extend the maturity date to May 2019. The bank lines are secured by a first lien on the Company’s North American OSB inventory and property, plant and equipment. This lien is shared pari passu with the holders of the 2020 and 2023 senior secured notes.

Merger with Ainsworth

On March 31, 2015, the Company's merger (the Merger) with Ainsworth was completed. Under the terms of the transaction, Norbord acquired all of the outstanding common shares of Ainsworth in an all-share transaction and Ainsworth shareholders received 0.1321 of a share of Norbord for each Ainsworth share. Norbord issued 31,830,328 Common Shares to Ainsworth shareholders on closing. Ainsworth common shares were de-listed from the TSX on April 2, 2015. A business acquisition report prepared in connection with the Merger was filed on the System for Electronic Document Analysis and Retrieval (SEDAR) at www.sedar.com.

Other Developments

In April 2015, the Company issued $315 million in senior secured notes due 2023 with an interest rate of 6.25%. The notes rank pari passu with the Company’s existing senior secured notes due in 2020 and committed revolving bank lines. The Company used the proceeds to redeem, prior to maturity, the outstanding $315 million senior secured notes of Ainsworth due in 2017 that were assumed upon closing of the Merger.

In April 2015, the Company amended its accounts receivable securitization program with a third-party trust sponsored by a highly rated Canadian financial institution, increasing the program commitment by $25 million to $125 million to reflect the Merger.

DESCRIPTION OF THE BUSINESS

Principal Products and Markets

Norbord’s business comprises the manufacturing, sales, marketing and distribution of panelboards and related products used primarily in the construction of new homes or the renovation and repair of existing structures. In general, the business is affected by the level of housing starts, the level of home repairs, the availability and cost of financing, changes in industry capacity, changes in raw material prices, changes in foreign exchange rates (primarily the Canadian dollar, Pound Sterling and Euro currencies) and other operating costs.

Products are primarily sold to major retail chains, contractor supply yards and industrial users. Some mill products are sold to industrial customers for further processing or as components for other products. Norbord OSB products are sold in North America under the following brand names: Durastrand pointSIX®, Pinnacle® and Stabledge® (premium flooring), TruFlor pointSIX® and TruFlor® (commodity flooring), SteadiTred® (industrial), QuakeZone®, Tallwall®, Trubord™ and Windstorm™ (wall sheathing) and SolarBord™ (radiant barrier sheathing), TruDeck® (flat roof sheathing for large industrial/commercial buildings), and StableDeck® (utility trailer floors). In Europe, Norbord products are sold under the trademarks SterlingOSB® (OSB), Caberwood MDF® (MDF), Conti® and Caberboard® (particleboard).

The Company operates in North America and Europe. Sales revenues by geographic segment are determined based on the origin of shipment. In 2017, 80% of Norbord’s sales originated from North America (2016 – 77%) and 20% from Europe (2016 – 23%).

North America is the principal market destination for Norbord’s products. In 2017 and 2016, Norbord’s panel shipments by volume originated as follows:

	2017		2016
North America	76	%	77	%
Europe	24	%	23	%
Total	100	%	100	%

OSB is used principally for sheathing, flooring and roofing in home construction. According to the APA – The Engineered Wood Association, OSB production represented approximately 67% of total 2017 North American structural panel production. In Europe, OSB’s share of the structural panel market is lower than in North America due mainly to different housing construction methods; however, OSB use is growing rapidly in Europe. Norbord’s particleboard is used primarily in flooring and other construction applications. MDF applications include cabinet doors, mouldings and interior wall paneling.

Principal Operating Interests

Information regarding Norbord’s estimated annual production capacity is set forth in the following table. The estimated annual production capacity is based on normal operating rates and normal production mixes under current market conditions, taking into account known constraints, such as permit restrictions. Factors such as market conditions, fluctuations in raw material availability, mechanical interruptions and the nature of current orders may cause actual production rates and mixes to vary significantly from the estimated production rates and mixes used to derive the estimated annual capacities shown.

(1) In November 2016, Norbord exchanged ownership of its Val-d’Or OSB mill for Louisiana-Pacific Corporation’s curtailed Chambord OSB mill (the Quebec Mill Exchange). Production at Chambord has been curtailed since the third quarter of 2008.

(2) In January 2009, Norbord indefinitely curtailed production at its Huguley, Alabama OSB mill. The mill subsequently resumed operations in October 2017.

(3) During the fourth quarter of 2017, the estimated annual capacity increased from 395 MMsf-3/8" based on the substantial completion of the Inverness expansion project.

In the US, Norbord employs multi-opening press technology at its Minnesota, Georgia, Mississippi, and two Texas OSB mills. Norbord employs continuous press technology at its South Carolina and Alabama OSB mills in the US. Continuous press technology allows for the production of OSB in non-standard sizes and with specialized performance characteristics. Most of the US mills’ production is sold in the domestic US market. All of these mills purchase their wood fibre requirements from outside sources with prices based on regional market dynamics. These mills are not unionized.

In Canada, Norbord also employs multi-opening press technology at its British Columbia OSB mill, one of the two Alberta (Grande Prairie) OSB mills, the Ontario OSB mill and the two Quebec OSB mills.

Norbord Inc. 2018 Annual Information Form Page 8

Norbord employs continuous press technology at its other Alberta (High Level) OSB mill. A significant portion of the production of the Canadian mills is shipped to the US and offshore export markets (Western mills). The wood fibre requirements for these mills are obtained primarily from Crown land under long-term forest management agreements with the provincial governments and also from other outside sources, with prices based on regional market dynamics. The two Alberta mills are non-unionized and the other Canadian mills are unionized.

All employees in the North American operating mills, with the exception of 100 Mile House, British Columbia and Barwick, Ontario, participate in profit sharing programs whereby a percentage of each mill’s operating income is shared equally across all employees at that mill.

Norbord’s mill in Cowie, Scotland is a large operation with a continuous press MDF production line and a continuous press particleboard line. The South Molton, England particleboard mill employs single-opening press technology and is integrated with laminating operations and a flat-pack furniture manufacturing facility. The OSB mill in Inverness, Scotland employs two multi-opening press lines which were replaced with one state-of-the-art continuous press line put into production in the fourth quarter of 2017. All of Norbord’s UK mills purchase their wood fibre requirements from outside sources with prices based on regional market dynamics. These mills are all unionized.

The Genk, Belgium OSB mill employs continuous press technology. The Genk mill purchases its wood fibre requirements on the open market from a combination of public and private sources in the region. The mill is unionized.

Manufacturing Inputs

Wood fibre, resin, wax and energy are the principal raw material inputs used in the production of Norbord’s panelboard products.

Wood Fibre

Norbord does not own any timberlands and purchases timber, wood chips and other wood fibre as well as recycled materials on the open market in competition with other users of such resources.

Norbord’s wood fibre supply comes from several different sources. In the US, roundwood logs are primarily sourced from private and industry-owned woodlands. In Canada, Norbord holds forest licences and agreements to source roundwood logs from Crown timberlands, which are supplemented by open market and private purchases. In Europe, wood fibre is purchased from government and private landowners.

Resin and Wax

Resin and wax is sourced through tolling arrangements with outside suppliers with prices for the underlying feedstocks based on global indices. These feedstocks are widely-used industrial chemicals derived from oil and gas, such as benzene, phenol and methanol. Feedstock prices are influenced by global supply and demand conditions, and have exhibited significant volatility over time.

Energy

Norbord’s manufacturing processes generate residual wood material that cannot be used in the final product. This biomass material can be used as a renewable energy source to produce heat. Of the 28 million MMBTU in total energy requirements, approximately 80% or 22 million MMBTU of Norbord’s total manufacturing energy needs and all of Norbord’s OSB process heat requirements are met with renewable biomass fuel.

Norbord also procures electricity and natural gas for its manufacturing and air emissions control processes. In 2017, Norbord consumed 4 million MMBTU of non-renewable fossil fuels, the majority of which was used to operate air emissions control equipment, power mobile equipment and provide residual process heat. Approximately 38% of natural gas consumption was used to generate 484 GW of electricity and provide process heat at Norbord’s Cowie, Scotland operations. Another 21% of natural gas consumption was used to operate regulatory required air emissions control equipment. An additional 849 GW of electricity is procured directly from local grids. Energy prices have experienced significant volatility in recent years, particularly in deregulated markets.

Seasonality and Cyclicality of Business

Quarterly financial results are impacted by seasonal factors such as weather and building activity. Market demand varies seasonally, as homebuilding activity and repair and renovation work – the principal end uses of Norbord’s products – are generally stronger in the spring and summer months. Adverse weather can also limit access to logging areas, which can affect the supply

Norbord Inc. 2018 Annual Information Form Page 9

of fibre to Norbord’s operations. Shipment volumes and commodity prices are affected by these factors as well as by global supply and demand conditions.

Operating working capital is typically built up in the first quarter of the year due primarily to winter log inventory purchases in the Northern regions of North America and Europe. This inventory is generally consumed in the spring and summer months.

Competitive Conditions

The wood-based panels industry is a highly competitive business environment in which companies compete, to a large degree, on the basis of price. Factors including production costs, freight charges and market dynamics between producing and consuming regions have an impact on the competitive position of all potential structural panel suppliers in a given market. OSB’s significant cost advantage over plywood continues to support long-term OSB market growth. Norbord’s principal market destination is the United States where it competes with North American and, in some instances, foreign producers. Most of Norbord’s European products are sold in the United Kingdom, Germany and the BeNeLux region where it competes primarily with other European producers.

Research and Development

Norbord carries out research and applied technology programs, identifying new techniques to improve production and product quality, develop new products and minimize the environmental impact of its operations. The Company operates a central laboratory facility in St. Laurent, Quebec. In addition, the Company performs contract work at a number of industry-wide organizations including FPInnovations and the Alberta Innovates Technology Futures aimed at reducing production costs and developing new products.

Environment, Health and Safety

Norbord’s Environment, Health and Safety Policies are available on Norbord’s website at www.norbord.com.

Norbord measures its performance against environment, health and safety targets in three areas: 1) injury frequency and severity; 2) environmental compliance; and 3) environment, health and safety management systems. Norbord conducts audits on its operations on a regular schedule to ensure continuing high standards of performance.

Norbord’s operations are subject to a range of general and industry-specific environmental laws and regulations relating to air emissions, wastewater discharges, solid and hazardous waste management, plant and wildlife protection and site remediation.

Approximately 80% of Norbord's manufacturing energy needs are met by renewable biomass fuel which makes Norbord's manufacturing processes a relatively small source of greenhouse gases (GHG). Norbord operations emit approximately 246 KT of Scope 1 GHG annually from energy consumption.

In the fall of 2016, the Paris Agreement (Agreement) resulting from the United Nations Framework Convention on Climate Change entered into force. At present, Canada, the European Union and the United Kingdom have all ratified the agreement. The Canadian federal government and the four provinces in which Norbord operates have enacted regulations to meet GHG reduction obligations through carbon taxes or cap-and-trade initiatives. Currently, none of these programs have a significant direct financial impact on Norbord’s operations. The United States has withdrawn from the Agreement. There are currently no GHG regulatory initiatives that are expected to negatively impact Norbord’s US operations.

All of Norbord’s UK operations entered into the Kyoto climate change energy efficiency agreements in 2001, which has to-date resulted in more than £51 million in tax and energy efficiency cost savings. A cap-and-trade carbon trading program has been in place in Europe since 2005. Biomass heat energy generating units have enabled the European mills to comply with energy efficiency targets and have resulted in a surplus of carbon credits and renewable heat incentives (RHI) across Norbord’s European business. Since 2005 surplus credits traded on environmental exchanges and RHI payments have resulted in approximately £7 million in additional income. Norbord expects to have sufficient credits to meet 2017 compliance commitments.

Norbord holds third party verified sustainable forest management and fibre sourcing certification from the Sustainable Forestry Initiative® (SFI®) program, and chain-of-custody certificates from the SFI® program and the Forest Stewardship Council® forest certification program and the Programme for the Endorsement of Forest Certification (PEFC).

Norbord Inc. 2018 Annual Information Form Page 10

Human Resources

Norbord’s corporate head office is in Toronto, Canada. Norbord employs approximately 2,750 people at its operations in the US, Canada and Europe. Approximately 35% of these employees are represented by labour unions. All of Norbord’s UK and Belgian union contracts are evergreen. Norbord’s North American union contracts expire as follows:

Union	Mill Covered	Contract Expiry Date
Pulp, Paper and Woodworkers of Canada (PPWC)	100 Mile House, BC	In negotiation(1)
Unifor	Barwick, ON	In negotiation(1)
Unifor	La Sarre, QC	June 30, 2021
Unifor	Chambord, QC(2)	June 1, 2026

(1) expected to be concluded in Q1 2018

(2) mill indefinitely curtailed

RISKS OF THE BUSINESS

Norbord is exposed to a number of risks and uncertainties in the normal course of its business which could have a material adverse effect on the Company’s business, financial position, operating results and cash flows. A discussion of some of the major risks and uncertainties follows.

Product Concentration and Cyclicality

OSB accounts for approximately 90% of Norbord’s panel production capacity. The price of OSB is one of the most volatile in the wood products industry. Norbord’s concentration on OSB increases its sensitivity to product pricing and may result in a high degree of sales and earnings volatility.

Norbord’s financial performance is principally dependent on the selling price of its products. Most of Norbord’s products are traded commodities for which no liquid futures markets exist. The markets for most of Norbord’s products are highly cyclical and characterized by periods of supply and demand imbalance, during which its product prices have tended to fluctuate significantly. In addition, since many of Norbord’s products are used for new home construction, seasonal and annual weather changes can affect demand and sales volumes. These imbalances, which may affect different areas of Norbord’s business at different times, are influenced by numerous factors that are beyond Norbord’s control and include: changes in global and regional production capacity for a particular product or group of products; changes in the end use of those products, or the increased use of substitute products; a significant increase in longer-term interest rates; changes in the availability of mortgage financing; and the overall level of economic activity in the regions in which Norbord conducts business. In the past, Norbord has been negatively affected by declines in product pricing and has taken production downtime to manage working capital and minimize cash losses. Severe and prolonged weakness in the markets for Norbord’s products, particularly OSB, could seriously harm the Company’s financial position, operating results and cash flows, including the ability to satisfy interest and principal payments on outstanding debt.

Based on operations running at full capacity, the following table shows the approximate annualized impact of changes in realized product prices on Adjusted EBITDA:

	Sensitivity Factor	Impact on    Adjusted EBITDA(1)  (US $ millions)
OSB – North America	$10 per Msf–7/16”	$59(2)
OSB – Europe	€10 per m3	12

⁽¹⁾  Norbord defines Adjusted EBITDA as earnings (loss) determined in accordance with International Financial Reporting Standards (IFRS) before finance costs, income taxes, depreciation and amortization and other unusual or non-recurring items. Adjusted EBITDA is a non-IFRS financial measure that does not have any standardized meaning prescribed by IFRS and is therefore unlikely to be comparable to similar measures presented by other companies. See the Non-IFRS Financial Measures section in Norbord’s 2017 Management’s Discussion and Analysis dated February 1, 2018 for a quantitative reconciliation of Adjusted EBITDA to earnings (the most directly comparable IFRS measure).

⁽²⁾    Impact on Adjusted EBITDA of a $10 per Msf-7/16” change is ± $[50] million based on the last twelve months of production.

Liquidity

Norbord relies on long-term borrowings, access to revolving bank lines and an accounts receivable securitization program to fund its ongoing operations. The Company’s ability to refinance or renew such facilities is dependent upon financial market

Norbord Inc. 2018 Annual Information Form Page 11

conditions. Although Norbord has notes maturing in 2020 and 2023 and has bank lines that are committed to May 2019, financing may not be available when required or may not be available on commercially favourable or otherwise satisfactory terms in the future.

Competition

The wood-based panels industry is a highly competitive business environment in which companies compete, to a large degree, on the basis of price. Norbord’s principal market is the US, where it competes with North American and, in some instances, foreign producers. Norbord’s European operations compete primarily with other European producers. Certain competitors may have lower-cost facilities than Norbord. Norbord’s ability to compete in these and other markets is dependent on a variety of factors, such as manufacturing costs, availability of key production inputs, continued free access to markets, customer service, product quality, financial resources and currency exchange rates. In addition, competitors could develop new cost-effective substitutes for Norbord’s wood-based panels, or building codes could be changed making the use of Norbord’s products less attractive for certain applications.

Customer Dependence

Norbord sells its products primarily to major retail chains, contractor supply yards and industrial manufacturers, and faces strong competition for the business of significant customers. In 2017, Norbord had one customer whose purchases represented greater than 10% of total sales. Norbord generally does not have contractual assurances of future sales. As a result, the loss of a significant customer or any significant customer order cancellations could negatively affect the Company’s sales and earnings. Continued consolidation in the retail industry could expose Norbord to increased concentration of customer dependence and increase customers’ ability to exert pricing pressure on Norbord.

Cross Border Trade

Norbord’s future performance is dependent upon international trade and, in particular, cross border trade between Canada and the United States and between the United Kingdom and European Union. Access to markets in the United States and other countries may be affected from time to time by various trade-related events. The Company’s financial condition and results of operations could be materially adversely affected by trade rulings, the failure to reach or adopt trade agreements, the imposition of customs duties or other tariffs, or an increase in trade restrictions in the future.

Manufacturing Inputs

Norbord is exposed to commodity price risk on most of its manufacturing inputs, which principally comprise wood fibre, resin, wax and energy. These manufacturing inputs are purchased primarily on the open market in competition with other users of such resources, and prices are influenced by factors beyond the Company’s control. Norbord may not be able to hedge the purchase price of manufacturing inputs or pass increased costs on to its customers.

Fibre Resource

Fibre for Norbord’s OSB mills comes from roundwood logs while the MDF and particleboard mills source fibre in the form of roundwood logs, wood chips, sawdust and recycled wood. Norbord’s wood fibre supply comes from several different sources. In the US, roundwood logs are primarily sourced from private and industry-owned woodlands. In Canada, Norbord holds forest licences and agreements to source roundwood logs from Crown timberlands, which are supplemented by open market and private purchases. In Europe, wood fibre is purchased from government and private landowners.

When Norbord purchases timber, wood chips, fibre and other wood recycled materials on the open market, it is in competition with other uses of such resources, where prices are influenced by factors beyond Norbord’s control. Fibre supply could also be influenced by natural events, such as forest fires, severe weather conditions, insect epidemics and other natural disasters, which may increase wood fibre costs, restrict access to wood fibre or force production curtailments. In addition, Norbord’s supply and cost of fibre may be negatively impacted by increased demand resulting from market-based or legislative initiatives to use wood-based biomass materials in the production of heat, electricity or other bio-based products.

In Canada, the Crown licences and agreements require the payment of stumpage fees for the timber harvested and compliance with specified operating, rehabilitation and silviculture management practices. They can be revoked or cancelled for non-performance and contain terms and conditions that could, under certain circumstances, result in a reduction of annual allowable timber that may be harvested by Norbord without any compensation. The Company may not be able to renew or replace the

Norbord Inc. 2018 Annual Information Form Page 12

Crown licences when they come due. Any changes to government regulations and policies governing forest management practices could adversely affect the Company’s access to, or increase the cost of, wood fibre.

Aboriginal groups have claimed substantial portions of land in various Canadian provinces over which they claim aboriginal title, or in which they have a traditional interest, and for which they are seeking compensation from various levels of government. The results of these claims and related forest policy mechanisms may adversely affect the supply of wood fibre and the commercial terms of supply agreements with provincial governments.

Currency Exposures

Norbord reports its financial results in US dollars. A portion of Norbord’s product prices and costs are influenced by relative currency values (particularly the Canadian dollar, Pound Sterling and Euro). Significant fluctuations in relative currency values could negatively affect the cost competitiveness of the Company’s facilities, the value of its foreign investments, the results of its operations and its financial position.

Norbord’s foreign exchange exposure arises from the following sources:

• net investments in foreign operations, limited to Norbord’s investment in its European operations which transact in both Pounds Sterling and Euros;

• net Canadian dollar-denominated monetary assets and liabilities; and

• committed or anticipated foreign currency-denominated transactions, primarily Canadian dollar costs in Norbord’s Canadian operations and Euro revenues in Norbord’s UK operations.

Third-Party Transportation Services

Norbord relies on third-party transportation services for delivery of products to customers as well as for delivery of raw materials from suppliers. The majority of products manufactured and raw materials used are transported by rail or truck, which are highly regulated. Transportation rates and fuel surcharges are influenced by factors beyond Norbord’s control. Any failure of third-party transportation providers to deliver finished goods or raw materials in a timely manner, including failure caused by adverse weather conditions could harm the Company’s reputation, negatively affect customer relationships or disrupt production at the Company’s mills.

Employee Retention and Labour Relations

Norbord’s success depends in part on its ability to attract and retain senior management and other key employees. Competition for qualified personnel depends on economic and industry conditions, competitors’ hiring practices and the effectiveness of Norbord’s compensation programs. The loss of, or inability to recruit and retain, any such personnel could impact the Company’s ability to execute on its strategy.

Norbord’s US employees are non-unionized while its UK, Belgian and most of its Canadian mill employees are unionized – representing approximately 35% of the workforce. All of Norbord’s UK and Belgian union contracts are evergreen. Canadian union contracts typically cover a three- to five-year term, and the current contracts with Unifor representing members at the OSB mills in La Sarre, Quebec and Chambord, Quebec expire June 30, 2021 and June 1, 2026, respectively. The contract with Unifor representing members at the Barwick, Ontario mill expired on July 31, 2017 and is currently being renegotiated. The contract with the Pulp, Paper and Woodworkers of Canada (PPWC) representing members at the OSB mill in 100 Mile House, British Columbia expired on June 30, 2017 and is currently being renegotiated. Strikes or work stoppages could result in lost production and sales, higher costs or supply constraints if Norbord is unable to negotiate acceptable contracts with its various trade unions upon expiry.

Environmental and Other Regulations

Norbord’s operations are subject to a range of general and industry-specific laws and regulations that apply to most of the Company's business activities. This includes environmental laws and regulations relating to air emissions, wastewater discharges, solid and hazardous waste management, plant and wildlife protection and site remediation. Further, the Company is required to obtain approvals, permits and licences for the operation of its manufacturing facilities which impose conditions that must be complied with. Failure to comply with applicable laws and regulations could result in fines, penalties or other enforcement actions that could impact Norbord’s production capacity or increase its production costs. The Company has incurred, and expects to continue to incur, capital expenditures and operating costs to comply with applicable laws and regulations. In addition, laws and regulations could become more stringent or subject to different interpretation in the future.

Norbord Inc. 2018 Annual Information Form Page 13

International Sales

A portion of the Company’s sales are exported to customers in developing markets. International sales present a number of risks and challenges, including but not limited to the effective marketing of the Company’s products in foreign countries, collectability of accounts receivable, tariffs and other barriers to trade and recessionary environments in foreign economies. Although the Company purchases credit insurance on all export sales, revenues could be negatively impacted by any customer losses.

Product Liability and Legal Proceedings

Norbord produces a variety of wood-based panels that are used in new home construction, repair-and-remodelling of existing homes, furniture and fixtures, and industrial applications. In the normal course of business, the end users of Norbord’s products have in the past made, and could in the future make, claims with respect to the fitness for use of its products or claims related to product quality or performance issues. In addition, Norbord has been in the past and may in the future be involved in legal proceedings related to antitrust, negligence, personal injury, property damage and other claims against the Company or its predecessors. Norbord could face increased costs if any future claims exceed purchased insurance coverage.

Capital Intensity

The production of wood-based panels is capital intensive. There can be no assurance that key pieces of equipment will not need to be repaired or replaced, or that operation of the Company's manufacturing facilities could not otherwise be disrupted unexpectedly, for example by adverse weather, power outages, fire, explosion or other hazards. In certain circumstances, the costs of repairing or replacing equipment, and the associated downtime of the affected production line, may not be insurable.

Tax Exposures

In the normal course of business, Norbord takes various positions in the filing of its tax returns, and there can be no assurance that tax authorities will not challenge such filing positions. In addition, Norbord is subject to further uncertainties concerning the interpretation and application of tax laws in various operating jurisdictions. Norbord provides for known estimated tax exposures in all jurisdictions. These exposures are settled primarily through the closure of audits with the jurisdictional taxing authorities. However, future settlements could differ materially from the Company’s estimated liabilities.

Potential Future Changes in Tax Laws

The Company’s structure is based on prevailing taxation law and practice in the local jurisdictions in which it operates. The Company is aware that new taxation rules could be enacted or that existing rules could be applied in a manner that subjects its profits to additional taxation or otherwise has a material adverse effect on its profitability, results of operations, financial condition or the trading price of its securities. Management is continually monitoring changes in tax policy, tax legislation (including in relation to taxation rates), and the interpretation of tax policy or legislation or practice that could have such an effect.

US Tax Reform Legislation

On December 22, 2017, the US government enacted H.R. 1, An Act to provide for reconciliation pursuant to titles II and V of the concurrent resolution on the budget for fiscal year 2018 (informally titled the Tax Cuts and Jobs Act). Among a number of significant changes to the US federal income tax laws, the Tax Cuts and Jobs Act reduces the marginal US corporate income tax rate from 35% to 21%, limits the deduction for net interest expense, shifts the US toward a modified territorial tax system, and imposes new taxes to combat erosion of the US federal income tax base. Although the Company has recognized a net income tax recovery due to the reduction of the income tax rate, the long-term tax effect of the Tax Cuts and Jobs Act on Norbord, whether adverse or favourable, is uncertain, and may not become evident for some period of time.

Norbord Inc. 2018 Annual Information Form Page 14

Defined Benefit Pension Plan Funding

Although Norbord’s defined benefit pension plans are largely closed to new entrants, the Company continues to be subject to market risk on the plan assets and obligations related to existing members. Defined benefit pension plan funding requirements are based on actuarial valuations that make assumptions about the long-term expected rate of return on assets, salary escalation, life expectancy and discount rates. The Company’s latest funding valuations indicate the plans are in a solvency deficit position and therefore Norbord is required to make cash funding contributions. If actual experience differs from these assumptions or any of these assumptions change such that the solvency deficit increases, the Company would be required to increase cash funding contributions, reducing the availability of such funds for other corporate purposes.

Information Technology Infrastructure

In order to optimize performance, the Company regularly implements business process improvement initiatives and invests capital to upgrade its information technology infrastructure. These initiatives may involve risks to the operations and the Company may experience difficulties during the transition to these new or upgraded systems and processes. Difficulties in implementing new or upgraded information systems or significant system failures could disrupt operations and have a material adverse effect on the business.

Cyber Security

Norbord relies on information technology to support the Company’s operations and to maintain business records. Some systems are internally managed and some are maintained by third-party service providers. Norbord and its service providers employ what the Company believes are adequate security measures. A security failure of that technology, security breaches of company, customer, employee and vendor information as well as a disruption of business resulting from a natural disaster, hardware or software corruption, failure or error, telecommunications system failure, service provider error, intentional or unintentional personnel actions or other disruptions could disrupt operations and have a material adverse effect on the business. Further, such disruptions could expose the Company to potential liability or other proceedings by affected individuals, business partners and/or regulators. As a result, Norbord could face increased costs if any future claims exceed purchased insurance coverage.

Description of Debt Securities

In February 2017, the Company permanently repaid its $200 million senior secured notes upon maturity using cash on hand and temporary drawings on its accounts receivable securitization program which were repaid in the second quarter of 2017.

At February 1, 2018, Norbord had issued and outstanding senior debt securities as follows:

• $240 million of 5.375% senior secured notes due December 1, 2020; and

• $315 million of 6.25% senior secured notes due April 1, 2023.

Credit Ratings

Maintaining a stable balance sheet is an important element of Norbord’s financing strategy. Norbord believes that its record of superior operational performance and prudent balance sheet management will enable it to access public and private capital markets (subject to financial market conditions).

As at February 1, 2018, the Company’s long-term debt and issuer ratings were:

	DBRS		Standard &     Poor’s Ratings Services		Moody’s     Investors Service
Secured Notes		BB		BB+		Ba1
Issuer		BB		BB		Ba1
Outlook		Stable		Stable		Stable

Credit ratings are intended to provide investors with an independent measure of the credit quality of any securities issue. The credit ratings accorded to debt securities by the rating agencies are not recommendations to purchase, hold or sell the debt securities, as such ratings do not comment on market price or suitability for a particular investor. There is no assurance that any rating will remain in effect for any given period of time or that any rating will not be revised or withdrawn entirely by a rating agency in the future if, in its judgement, circumstances warrant.

DBRS credit ratings are on a long-term debt rating scale that ranges from AAA to D, which represents the range from highest to lowest quality of such securities rated. According to DBRS, a rating of BB is the fifth highest of ten major categories, and debt securities rated BB are defined to be speculative and non-investment grade. Rating categories AA through C are denoted by the subcategories “high” and “low”. The absence of either a “high” or “low” designation indicates the rating is in the “middle” of the category.

S&P credit ratings are on a long-term debt rating scale that ranges from AAA to D, which represents the range from highest to lowest quality of such securities rated. According to S&P, the BB rating is the fifth highest of ten major categories, and debt securities rated BB or lower are regarded as having significant speculative characteristics. Debt securities rated BB are less vulnerable to non-payment than other speculative issues; however, they face major ongoing uncertainties or exposure to adverse business, financial or economic conditions. The ratings from AA to CCC may be modified by the addition of a plus (+) or minus (–) sign to show relative standing within the major rating categories.

Moody’s credit ratings are on a long-term debt rating scale that ranges from Aaa to C, which represents the range from highest to lowest quality of such securities rated. According to Moody’s, a rating of Ba is the fifth highest of nine major categories, and debt securities rated Ba are judged to have speculative elements and are subject to substantial credit risk. Moody’s applies numerical modifiers 1, 2 and 3 in each generic rating classification from Aa through Caa. The modifier 1 indicates that the

Norbord Inc. 2018 Annual Information Form Page 16

security ranks in the higher end of its generic rating category, the modifier 2 indicates a mid-range ranking and the modifier 3 indicates a ranking in the lower end of that generic rating category.

DIVIDENDS

Norbord’s variable dividend policy targets the payment to shareholders of a portion of free cash flow based upon the Company’s financial position, results of operations, cash flow, capital requirements and restrictions under the Company’s revolving bank lines, as well as the market outlook for the Company’s principal products and broader market and economic conditions, among other factors. Under this policy, the Board of Directors has declared the following dividends:

(in C $)	Quarterly Dividend Declared per Common Share
Q2 2013 to Q4 2014	$	0.60
Q1 2015 & Q2 2015	0.25
Q3 2015 to Q1 2017	0.10
Q2 2017	0.30
Q3 2017	0.50
Q4 2017	0.60

The dividend level was decreased twice during 2015 to maintain flexibility in the Company’s capital structure as well as to fund growth and other attractive capital investment opportunities.  The dividend level was increased three times during 2017, reflecting the strength in North American benchmark OSB prices last year and resulting robust operating cash flow for the Company, the positive market outlook for the Company’s products and the continuing expectation that free cash flow will be sufficient to fund current growth and other capital investment commitments for the foreseeable future.

The Board retains the discretion to amend the Company’s dividend policy in any manner and at any time as it may deem necessary or appropriate in the future. For these reasons, as well as others, the Board in its sole discretion can decide to increase, maintain, decrease, suspend or discontinue the payment of cash dividends in the future.

The Company has a Dividend Reinvestment Plan (DRIP) whereby shareholders resident in Canada or the United States can elect to receive their dividends in Common Shares.

The table below summarizes the total dividends on Common Shares declared by the Board, the amounts paid out in cash and the amounts distributed as shares under the DRIP for the preceding three financial years.

($ millions)	2017		2016		2015
Cash distribution	$	101	$	26	$	40
Share distribution(1)	—		—		—
Total dividends on Common Shares	$	101	$	26	$	40

(1) Common Shares distributed in the DRIP represented less than $1 million in 2017, 2016 and 2015. All Common Shares were issued from treasury.
