Notes to Unaudited Condensed Consolidated Financial Statements

NOTE 1 - BASIS OF PRESENTATION AND SIGNIFICANT ACCOUNTING POLICIES

The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with SEC rules and regulations and, in the opinion of management, include all adjustments (consisting of normal recurring adjustments) necessary to present fairly the financial position, results of operations, comprehensive loss and cash flows for the periods presented. The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Management bases its estimates on various assumptions and historical experience, which are believed to be reasonable; however, due to the inherent nature of estimates, actual results may differ significantly due to changed conditions or assumptions. The results of operations for the three months endedMarch 31, 2019 are not necessarily indicative of results to be expected for the year ending December 31, 2019 or any other future period. These unaudited condensed consolidated financial statements should be read in conjunction with the financial statements and notes included in our Annual Report on Form 10-K for the year ended December 31, 2018.

As more fully described in the Form 10-K for the year ended December 31, 2018, in 2018 we committed to a course of action leading to the permanent closure of the Asia Pacific Iron Ore mining operations and, as planned, completed our final shipment in June 2018. Factors considered in this decision included increasingly discounted prices for lower-iron-content ore and the quality of the remaining iron ore reserves.

During 2018, we sold all of the assets of our Asia Pacific Iron Ore business through a series of sales to third parties.As a result of our planned exit, management determined that our Asia Pacific Iron Ore operating segment met the criteria to be classified as held for sale and a discontinued operation under ASC Topic 205, Presentation of Financial Statements. As such, all Asia Pacific Iron Ore operating segment results are classified within discontinued operations. Refer to NOTE 14 - DISCONTINUED OPERATIONS for further information.

We have two reportable segments - the Mining and Pelletizing segment and the Metallics segment. Unless otherwise noted, discussion of our business and results of operations in this Quarterly Report on Form 10-Q refers to our continuing operations.

Basis of Consolidation

The unaudited condensed consolidated financial statements include our accounts and the accounts of our wholly-owned subsidiaries, including the following operations as of March 31, 2019:

Name	Location	Business Segment	Status of Operations
Northshore	Minnesota	Mining and Pelletizing	Active
United Taconite	Minnesota	Mining and Pelletizing	Active
Tilden	Michigan	Mining and Pelletizing	Active
Empire	Michigan	Mining and Pelletizing	Indefinitely Idled
Toledo HBI	Ohio	Metallics	Construction Stage

Intercompany transactions and balances are eliminated upon consolidation.

Equity Method Investments

Our 23% ownership interest in Hibbing is recorded as an equity method investment. As of March 31, 2019 and December 31, 2018, our investment in Hibbing was $10.8 million and $15.4 million, respectively, classified as Other liabilities in the Statements of Unaudited Condensed Consolidated Financial Position.

Significant Accounting Policies

A detailed description of our significant accounting policies can be found in the audited financial statements for the fiscal year ended December 31, 2018 included in our Annual Report on Form 10-K filed with the SEC. There have been no material changes in our significant accounting policies and estimates from those disclosed therein.

NOTE 2 - NEW ACCOUNTING STANDARDS

Issued and Adopted

In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842). The new standard requires lessees to recognize a right-of-use asset and a lease liability on the balance sheet for all leases except for short-term leases. For lessees, leases will be classified as either operating or finance leases in the Statements of Unaudited Condensed Consolidated Operations. We adopted this standard on its effective date of January 1, 2019 using the optional alternative approach, which requires application of the new guidance at the beginning of the standard's effective date. Adoption of the updated standard did not have a material effect on our consolidated financial statements.

Issued and Not Effective

In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments–Credit Losses (Topic 326), which introduces a new accounting model, CECL. CECL requires earlier recognition of credit losses, while also providing additional transparency about credit risk. The CECL model utilizes a lifetime expected credit loss measurement objective for the recognition of credit losses for receivables at the time the financial asset is originated or acquired. The expected credit losses are adjusted each period for changes in expected lifetime credit losses. We plan to adopt this standard on its effective date of January 1, 2020, and are currently evaluating the impact of this standard on our financial statements.

NOTE 3 - SEGMENT REPORTING

In alignment with our strategic goals, our Company’s continuing operations are organized and managed in two operating segments according to our differentiated products. Our Mining and Pelletizing segment is a major supplier of iron ore pellets to the North American steel industry from our mines and pellet plants located in Michigan and Minnesota. In our Metallics segment, we are currently constructing an HBI production plant in Toledo, Ohio. We expect to complete construction and begin production in 2020.

We evaluate performance based on sales margin, defined as revenues less cost of goods sold identifiable to each segment. Additionally, we evaluate performance on a segment basis, as well as a consolidated basis, based on EBITDA and Adjusted EBITDA. These measures allow management and investors to focus on our ability to service our debt as well as illustrate how the business is performing.  Additionally, EBITDA and Adjusted EBITDA assist management and investors in their analysis and forecasting as these measures approximate the cash flows associated with operational earnings.

The following tables present a summary of our reportable segments including a reconciliation of segment sales margin to Income (loss) from Continuing Operations Before Income Taxes and a reconciliation of Net loss to EBITDA and Adjusted EBITDA:

NOTE 4 - REVENUE

We sell primarily a single product, iron ore pellets, in the North American market. Revenue is recognized generally when iron ore is delivered to our customers. Revenue is measured at the point that control transfers and represents the amount of consideration we expect to receive in exchange for transferring goods. We offer standard payment terms to our customers, generally requiring settlement within 30 days.

We enter into supply contracts of varying lengths to provide customers iron ore pellets to use in their blast furnaces. Blast furnaces run continuously with a constant feed of iron ore and, once shut down, cannot easily be restarted. As a result, we ship iron ore in large quantities for storage and use by customers at a later date. Customers do not simultaneously receive and consume the iron ore. Based on our assessment of the factors that indicate the pattern of satisfaction, we transfer control of the iron ore at a point in time upon shipment or delivery of the product. The customer is able to direct the use of, and obtain substantially all of the benefits from, the product at the time the product is delivered.

Most of our customer supply agreements specify a provisional price, which is used for initial billing and cash collection. Revenue recorded in accordance with Topic 606 is calculated using the expected revenue rate at the point when control transfers. The final settlement includes market inputs for a specified period of time, which may vary by customer, but typically include one or more of the following published rates: Platts 62% Price, Atlantic Basin pellet premiums, Platts international indexed freight rates and changes in specified Producer Price Indices, including industrial commodities, fuel and steel. Changes in the expected revenue rate from the date control transfers through final settlement of contract terms is recorded in accordance with Topic 815. Refer to NOTE 13 - DERIVATIVE INSTRUMENTS for further information on how our estimated and final revenue rates are determined.

A supply agreement with a customer provides for supplemental revenue or refunds based on the average annual daily market price for hot-rolled coil steel in the year the iron ore is consumed in the customer’s blast furnaces. As control transfers prior to consumption, the supplemental revenue is recorded in accordance with ASC Topic 815. Refer to NOTE 13 - DERIVATIVE INSTRUMENTS for further information on supplemental revenue or refunds.

Included within Revenues from product sales and services is derivative revenue related to Topic 815 of $5.5 million and $43.8 million, for three months endedMarch 31, 2019 and 2018, respectively.

The terms of one of our pellet supply agreements required supplemental payments to be paid by the customer during the period 2009 through 2012. Installment amounts received under this arrangement in excess of sales were classified as Other current liabilities and Other liabilities in the Statements of Unaudited Condensed Consolidated Financial Position upon receipt of payment. Revenue is recognized over the life of the supply agreement, which extends until 2022, in equal annual installments. As of March 31, 2019 and December 31, 2018, installment amounts received in excess of sales totaled $51.4 million related to this agreement. As of March 31, 2019 and December 31, 2018, deferred revenue of $12.9 million was recorded in Other current liabilities and $38.5 million was recorded as long-term in Other liabilities in the Statements of Unaudited Condensed Consolidated Financial Position, related to this agreement.

Due to the payment terms and the timing of cash receipts near a period end, cash receipts can exceed shipments for certain customers. Revenue recognized on these transactions totaling $5.3 million and $8.2 million was deferred and included in Other current liabilities in the Statements of Unaudited Condensed Consolidated Financial Position as of March 31, 2019 and December 31, 2018, respectively.

Total	$	—	$	3.7	$	—	$	3.7

Financial assets classified in Level 1 included money market funds. The valuation of these instruments is based upon unadjusted quoted prices for identical assets in active markets.

The valuation of financial assets and liabilities classified in Level 2 is determined using a market approach based upon quoted prices for similar assets and liabilities in active markets, or other inputs that are observable. Level 2 assets include commercial paper, certificates of deposit and commodity hedge contracts. Level 2 liabilities include commodity hedge contracts.

The Level 3 assets and liabilities include derivative assets that consist of freestanding derivative instruments related to a certain supply agreement and derivative assets and liabilities related to certain provisional pricing arrangements with our customers.

The supply agreement included in our Level 3 assets contains provisions for supplemental revenue or refunds based on the average annual daily market price for hot-rolled coil steel in the year the iron ore product is consumed in the customer’s blast furnaces. We account for these provisions as derivative instruments at the time of sale and adjust the derivative instruments to fair value through Product revenues each reporting period until the product is consumed and the amounts are settled. We had assets of $106.4 million and $89.3 million at March 31, 2019 and December 31, 2018, respectively, related to this supply agreement.

The provisional pricing arrangements included in our Level 3 assets/liabilities specify provisional price calculations, where the pricing mechanisms generally are based on market pricing, with the final revenue rate to be based on market inputs at a specified point in time in the future, per the terms of the supply agreements. The difference between the estimated final revenue rate at the date of sale and the estimated final revenue rate at the measurement date is characterized as a derivative and is required to be accounted for separately once the revenue has been recognized. The derivative instruments are adjusted to fair value through Product revenues each reporting period based upon current market data and forward-looking estimates provided by management until the final revenue rates are determined. We had assets of $0.3 million and liabilities of $9.8 million related to provisional pricing arrangements at March 31, 2019 compared to assets of $2.1 million related to provisional pricing arrangements at December 31, 2018.

Provisional pricing arrangements	$	9.8	Other current liabilities	Market Approach	PPI Estimates	180 - 240 (208)
					Management's Estimate of Platts 62% Price per dry metric ton for respective contract period	$80

The significant unobservable input used in the fair value measurement of our customer supply agreement is a forward-looking estimate of the average annual daily market price for hot-rolled coil steel determined by management.

The significant unobservable inputs used in the fair value measurement of our provisional pricing arrangements include estimates for PPI data and management’s estimate of Platts 62% Price based upon current market data and index pricing, which include forward-looking estimates determined by management.

NOTE 9 - PENSIONS AND OTHER POSTRETIREMENT BENEFITS

We offer defined benefit pension plans, defined contribution pension plans and OPEB plans, primarily consisting of retiree healthcare benefits, to most employees as part of a total compensation and benefits program. The defined benefit pension plans are noncontributory and benefits generally are based on a minimum formula or employees’ years of service and average earnings for a defined period prior to retirement.

The following are the components of defined benefit pension and OPEB costs:

Based on funding requirements, we made pension contributions of $3.2 million for the three months endedMarch 31, 2019, compared to pension contributions of $2.3 million for the three months endedMarch 31, 2018. OPEB contributions are typically made on an annual basis in the first quarter of each year, but due to plan funding requirements being met, no OPEB contributions were required or made for the three months endedMarch 31, 2019 and 2018.

NOTE 10 - STOCK COMPENSATION PLANS

Employees’ Plans

On February 19, 2019, the Compensation Committee approved grants under the A&R 2015 Equity Plan to certain officers and employees for the 2019 to 2021 performance period. Shares granted under the awards consisted of 0.6 million restricted stock units and 0.6 million performance shares.

Restricted stock units granted during 2019 are subject to continued employment, are retention based and are payable in common shares. The outstanding restricted stock units that were granted in 2019 cliff vest on December 31, 2021.

Performance shares are subject to continued employment, and each performance share, if earned, entitles the holder to be paid out in common shares. Performance is measured on the basis of relative TSR for the period of January 1, 2019 to December 31, 2021 and measured against the constituents of the SPDR S&P Metals and Mining ETF Index at the beginning of the relevant performance period. The final payouts for the outstanding performance period grants will vary from zero to 200% of the original grant depending on whether and to what extent the Company achieves certain objectives and performance goals as established by the Compensation Committee.

Determination of Fair Value

The fair value of each performance share grant is estimated on the date of grant using a Monte Carlo simulation to forecast relative TSR performance. A correlation matrix of historic and projected stock prices was developed for both the Company and our predetermined peer group of mining and metals companies. The fair value assumes that the objective will be achieved.

The expected term of the grant represents the time from the grant date to the end of the service period. We estimate the volatility of our common shares and that of the peer group of mining and metals companies using daily price intervals for all companies. The risk-free interest rate is the rate at the grant date on zero-coupon government bonds with a term commensurate with the remaining life of the performance period.

The following assumptions were utilized to estimate the fair value for the 2019 performance share grant:

Grant Date	Grant Date Market Price		Average Expected Term (Years)	Expected Volatility	Risk-Free Interest Rate	Dividend Yield	Fair Value		Fair Value (Percent of Grant Date Market Price)
February 19, 2019	$	11.24	2.87	67.5%	2.55%	—%	$	18.31	162.90%

18

NOTE 11 - INCOME TAXES

Our 2019 estimated annual effective tax rate before discrete items is 12.9%. The estimated annual effective tax rate differs from the U.S. statutory rate of 21.0% primarily due to the deductions for percentage depletion in excess of cost depletion related to U.S. operations. The 2018 estimated annual effective tax rate before discrete items at March 31, 2018 was 0.1%. The rate in the comparable prior-year period was significantly lower due to the reversal of valuation allowance in the same period.

For the three months endedMarch 31, 2019 and 2018, we recorded discrete items that resulted in an income tax benefit of $0.4 million and expense of $15.7 million, respectively. The prior-year period expense of $15.7 million primarily relates to the $14.5 million reduction of the refundable AMT credit recorded in Income tax receivable, non-current in our Statements of Unaudited Condensed Consolidated Financial Position based on the sequestration guidance issued by the Internal Revenue Service during the first quarter of 2018. This position was subsequently reversed by the Internal Revenue Service during the fourth quarter of 2018. The prior-year period expense was a $15.7 million reduction of an asset and did not result in a cash tax outlay.

NOTE 12 - ENVIRONMENTAL AND MINE CLOSURE OBLIGATIONS

Mine Closure

The accrued closure obligation for our active mining operations provides for contractual and legal obligations associated with the eventual closure of the mining operations. The closure date for each of our active operating mine sites was determined based on the exhaustion date of the remaining iron ore reserves. The closure date and expected timing of the capital requirements to meet our obligations for our indefinitely idled or closed mines is determined based on the unique circumstances of each property. For indefinitely idled or closed mines, the accretion of the liability is recognized over the anticipated timing of remediation. The amortization of the related asset and accretion of the liability is recognized over the estimated mine lives for our active operations.

The following represents a roll forward of our mine closure obligation liability for the three months ended March 31, 2019 and for the year ended December 31, 2018:

Derivatives Not Designated as Hedging Instruments

Customer Supply Agreement

A supply agreement with one customer provides for supplemental revenue or refunds to the customer based on the average annual daily steel market price for hot-rolled coil steel at the time the iron ore product is consumed in the customer’s blast furnace. The supplemental pricing is characterized as a freestanding derivative and is required to be accounted for separately once control transfers to the customer. The derivative instrument, which is finalized based on a future price, is adjusted to fair value through Product revenues each reporting period based upon current market data and forward-looking estimates provided by management until the pellets are consumed and the amounts are settled.

Provisional Pricing Arrangements

Certain of our supply agreements specify provisional price calculations, where the pricing mechanisms generally are based on market pricing, with the final revenue rate based on certain market inputs at a specified period in time in the future, per the terms of the supply agreements. Market inputs are tied to indexed price adjustment factors that are integral to the iron ore supply contracts and vary based on the agreement. The pricing mechanisms typically include

20

adjustments based upon changes in the Platts 62% Price, Atlantic Basin pellet premiums, Platts international indexed freight rates and changes in specified Producer Price Indices, including those for industrial commodities, fuel and steel. The pricing adjustments generally operate in the same manner, with each factor typically comprising a portion of the price adjustment, although the weighting of each factor varies based upon the specific terms of each agreement. The price adjustment factors have been evaluated to determine if they qualify as embedded derivatives. The price adjustment factors share the same economic characteristics and risks as the host contract and are integral to the host contract as inflation adjustments; accordingly, they have not been separately valued as derivative instruments.

Revenue is recognized generally upon delivery to our customers. Revenue is measured at the point that control transfers and represents the amount of consideration we expect to receive in exchange for transferring goods. Changes in the expected revenue rate from the date that control transfers through final settlement of contract terms is recorded in accordance with ASC Topic 815 and is characterized as a derivative and accounted for separately.  Subsequently, the derivative instruments are adjusted to fair value through Product revenues each reporting period based upon current market data and forward-looking estimates provided by management until the final revenue rate is determined.

The provisional amounts represent the difference between the amount we expect to receive when revenue was initially measured at the point control transfers and our subsequent estimate of the final revenue rate based on the price calculation established in the supply agreements.

Asia Pacific Iron Ore Operations

Background

In January 2018, we announced that we would accelerate the time frame for the planned closure of our Asia Pacific Iron Ore mining operations in Australia. In April 2018, we committed to a course of action leading to the permanent closure of the Asia Pacific Iron Ore mining operations and, as planned, completed our final shipment in June 2018. Factors considered in this decision included increasingly discounted prices for lower-iron-content ore and the quality of the remaining iron ore reserves.

During 2018, we sold all of the assets of our Asia Pacific Iron Ore business through a series of sales to third parties.As a result of our planned exit, management determined that our Asia Pacific Iron Ore operating segment met the criteria to be classified as held for sale and a discontinued operation under ASC Topic 205, Presentation of Financial Statements. As such, all Asia Pacific Iron Ore operating segment results are classified within discontinued operations.

NOTE 20 - COMMITMENTS AND CONTINGENCIES

Purchase Commitments

In 2017, we began to incur capital commitments related to the construction of our HBI production plant in Toledo, Ohio. In total, we expect to spend approximately $830 million on the HBI production plant, exclusive of construction-related contingencies and capitalized interest through 2020. Through March 31, 2019, we have entered into contracts and purchase orders for approximately $780 million of the total capital investment for the HBI production plant, of which a total of approximately $265 million has been expended project-to-date, including deposits. We expect expenditures of approximately $290 million during the remaining nine months of 2019. Of the remaining committed capital, expenditures of approximately $275 million are expected to be made during 2020.

Contingencies

We are currently the subject of, or party to, various claims and legal proceedings incidental to our operations. If management believes that a loss arising from these matters is probable and can reasonably be estimated, we record the amount of the loss or the minimum estimated liability when the loss is estimated using a range, and no point within the range is more probable than another. As additional information becomes available, any potential liability related to these matters is assessed and the estimates are revised, if necessary. Based on currently available information, management believes that the ultimate outcome of these matters, individually and in the aggregate, will not have a material effect on our financial position, results of operations or cash flows. However, these claims and legal proceedings are subject to inherent uncertainties and unfavorable rulings could occur. An unfavorable ruling could include monetary damages, additional funding requirements or an injunction. If an unfavorable ruling were to occur, there exists the possibility of a material impact on the financial position and results of operations for the period in which the ruling occurs or future periods. However, we do not believe that any pending claims or legal proceedings will result in a material liability in relation to our consolidated financial statements.

NOTE 21 - SUBSEQUENT EVENTS

We have evaluated subsequent events through the date of financial statement issuance.

On April 24, 2019, the Company’s Board of Directors authorized the Company to repurchase common shares in an additional amount of up to a maximum of $100 million. On November 24, 2018, the Company’s Board of Directors previously authorized share repurchases of up to a maximum amount of $200 million, and approximately $29 million of this earlier authorization remains available as of April 25, 2019. When combined with the additional amount of share repurchase authorization, the Company now has authorization to repurchase common shares up to a maximum of approximately $129 million as of April 25, 2019. Such share repurchases may be made via acquisitions in the open market or privately negotiated transactions, including through accelerated share repurchases or pursuant to the terms of a Rule 10b5-1 plan. The Company is not obligated to make any purchases and the program may be suspended or discontinued at any time. The authorization is active until December 31, 2019.

Item 2. Management's Discussion and Analysis of Financial Condition and Results of Operations

Management's Discussion and Analysis of Financial Condition and Results of Operations ("MD&A") is designed to provide a reader of our financial statements with a narrative from the perspective of management on our financial condition, results of operations, liquidity and other factors that may affect our future results. We believe it is important to read our MD&A in conjunction with our Annual Report on Form 10-K for the year ended December 31, 2018 as well as other publicly available information.

Overview

Founded in 1847, Cleveland-Cliffs Inc. is the largest and oldest independent iron ore mining company in the United States. We are a major supplier of iron ore pellets to the North American steel industry from our mines and pellet plants located in Michigan and Minnesota. By 2020, we expect to be the sole producer of HBI in the Great Lakes region with the development of our first production plant in Toledo, Ohio. Driven by the core values of safety, social, environmental and capital stewardship, our employees endeavor to provide all stakeholders with operating and financial transparency.

The key driver of our business is demand for steelmaking raw materials from U.S. steelmakers. During the first two months of 2019, the U.S. produced approximately 14 million metric tons of crude steel, which is up 7% when compared to the same period in 2018, or about 5% of total global crude steel production. U.S. total steel capacity utilization was approximately 82% in the first three months of 2019, which is an approximate 7% increase from the same period in 2018. Through the first two months of 2019, global crude steel production increased about 4% compared to the same period in 2018, driven by an approximate 9% increase in Chinese crude steel production.

Through the first quarter of the year, economic conditions surrounding the markets that influence our profitability were, in the aggregate, at their most favorable levels since 2014. In January 2019, a tailings dam operated by Vale S.A., the largest iron ore miner in the world, suffered a catastrophic failure resulting in hundreds of fatalities in Brumadinho,

34

Brazil. The fallout of this disaster has led to multiple disruptions in iron ore supply, leading to capacity reductions in the seaborne iron ore market. Due in large part to these disruptions, the Platts 62% Price, a key component in our pellet pricing arrangements, averaged $83 per metric ton in the first quarter, a 12% increase compared to $74 per metric ton in the first quarter of 2018.

The Vale S.A. incident in Brazil also intensified the already prevailing shortage in the iron ore pellet market. This shortage, along with the continued global focus on iron ore product quality, pushed pellet premiums higher during the first quarter. The Atlantic Basin pellet premium, another important pricing factor in our contracts, averaged $67 per metric ton for the first three months of 2019, a 16% increase compared to the same period in 2018. We believe the supply-demand dynamics of this market will continue to be favorable for us for the near term. Iron ore pellets remain scarce in the international market and new capacity is unlikely to come online in the near term due to the time and expense required to do so. We believe this scarcity will support and potentially increase these multi-year high premiums for pellet products in the foreseeable future.

The price for domestic hot-rolled coil steel, which is an important attribute in the calculation of supplemental revenue in a customer's supply agreement, averaged $692 per net ton for the first three months of 2019, 9% lower than the same period last year. While purchasers scrambled to place steel orders in the wake of the Section 232 tariffs implemented in the first quarter of 2018, the market has since normalized and prices have remained stable during the first quarter of 2019. While prices averaged a lower rate compared to the prior-year first quarter, they still remain well above the prior decade’s averages as tariffs have re-rated marginal import prices higher. Because the United States is the largest importer of steel in the world, we believe these tariffs should not only alleviate some national security concerns, but also keep the prices for domestic hot-rolled coil steel elevated above historical averages for as long as they remain in place. As such, we remain positive on our outlook for the domestic steel market.

For the three months ended March 31, 2019 and 2018, our consolidated revenues were $157.0 million and $180.0 million, respectively, with net loss from continuing operations per diluted share of $0.08 and $0.05, respectively.

First Quarter 2019 Recent Developments

Changes to our Executive Leadership

On February 12, 2019, Keith Koci was appointed Executive Vice President, Chief Financial Officer. Mr. Koci replaces Timothy K. Flanagan. Mr. Koci joins us from Metals USA Holdings Corp., where he served most recently as its Senior Vice President and Chief Financial Officer. Prior to that role, Mr. Koci served as Metals USA's Senior Vice President, Business Development from 2006 to 2013 and various other accounting and finance roles with increasing responsibility from 1998 to 2005.

Authorization for Additional Share Repurchases

On April 24, 2019, the Company’s Board of Directors authorized the Company to repurchase common shares in an additional amount of up to a maximum of $100 million. On November 24, 2018, the Company’s Board of Directors previously authorized share repurchases of up to a maximum amount of $200 million, and approximately $29 million of this earlier authorization remains available as of April 25, 2019. When combined with the additional amount of share repurchase authorization, the Company now has authorization to repurchase common shares up to a maximum of approximately $129 million as of April 25, 2019. Such share repurchases may be made via acquisitions in the open market or privately negotiated transactions, including through accelerated share repurchases or pursuant to the terms of a Rule 10b5-1 plan. The Company is not obligated to make any purchases and the program may be suspended or discontinued at any time. The authorization is active until December 31, 2019.

2 Cash cost of goods sold rate is a non-GAAP financial measure. Refer to "Non-GAAP Reconciliation" for reconciliation in dollars back to our consolidated financial statements.
3 Tons are long tons.

Sales margin was $30.9 million for the three months ended March 31, 2019, compared with $61.5 million for the three months ended March 31, 2018. Sales margin per long ton decreased 47.8% to $19.93 in the first three months of 2019 compared to the first three months of 2018.

Revenue decreased by $23.8 million during the three months ended March 31, 2019, compared to the prior-year period, excluding the domestic freight increase of $0.8 million. This was driven by a decrease in the average year-to-date realized product revenue rate of $11 per long ton, or 10.7%, during the three months ended March 31, 2019, compared to the first three months of 2018, which resulted in a decrease of $18 million. This is predominantly due to:

• Changes in hot-rolled coil steel pricing, which had a negative effect on the realized revenue rate of $19 per long ton, or $30 million, during the first three months of 2019 compared to the first three months of 2018. The imposition of the Section 232 actions increased the first quarter of 2018 actual pricing and our full-year estimates for hot-rolled coil steel in 2018. Additionally, due to current market trends, there has been a slight decrease in the full-year estimates for 2019.

• This decrease was offset partially by higher full-year estimated Platts 62% Price as of March 31, 2019, compared to the prior-year period's full-year estimated Platts 62% Price as of March 31, 2018, which positively affected the realized revenue rate by $8 per long ton, or $12 million.

Cost of goods sold increased $6.8 million during the three months ended March 31, 2019, excluding the domestic freight increase of $0.8 million, compared to the same period in 2018, predominantly as a result of an unfavorable change in the full-year standard cost driven by higher maintenance costs of $3 million, or $2 per long ton, reduced energy rebates

36

of $3 million, or $2 per long ton, increased transportation rates of $2 million, or $1 per long ton, higher stripping costs of $2 million, or $1 per long ton and increased royalties of $1 million, or $1 per long ton.

Production

Our share of production was relatively consistent for the three months ended March 31, 2019 when compared to the same period in 2018, decreasing approximately 2%.

Other Operating Income (Expense)

The following is a summary of Other operating expense:

Selling, general and administrative expenses for the three months endedMarch 31, 2019, had an unfavorable variance of $3.0 million, from the comparable period in 2018, primarily due to increased employment costs, including severance and incentive-based compensation.     

Other Income (Expense)

The following is a summary of Other income (expense):

	$	(25.0	)	$	(28.0	)	$	3.0

Interest expense, net for the three months ended March 31, 2019 was $7.3 million lower than the prior-year period, primarily due to capitalized interest related to the HBI production plant and upgrades at the Northshore plant. Additionally, debt restructuring activities during 2018 reduced the first quarter of 2019 interest expense.

37

Income Taxes

Our effective tax rate is impacted by permanent items, primarily depletion. It also is affected by discrete items that may occur in any given period but are not consistent from period to period. The following represents a summary of our tax provision and corresponding effective rates:

	(In Millions)
	Three Months Ended March 31,
	2019			2018			Variance
Income tax benefit (expense)	$	3.7		$	(15.7	)	$	19.4
Effective tax rate	14.3		%	682.7		%	(668.4		)%

Our tax provision for the three months ended March 31, 2019 was a benefit of $3.7 million and a 14.3% effective tax rate compared with a $15.7 million expense and a 682.7% effective tax rate for the comparable prior-year period. The difference in the effective rate and income tax expense from the comparable prior-year periods primarily relates to discrete items recorded in each period as well as the reversal of valuation allowance in the prior year.

For the three months endedMarch 31, 2019 and 2018, we recorded discrete items that resulted in an income tax benefit of $0.4 million and expense of $15.7 million, respectively. The prior year expense of $15.7 million primarily relates to the $14.5 million reduction of the refundable AMT credit recorded in Income tax receivable, non-current in our Statements of Unaudited Condensed Consolidated Financial Position based on the sequestration guidance issued by the Internal Revenue Service during the first quarter of 2018. This position was subsequently reversed by the Internal Revenue Service during the fourth quarter of 2018. The prior-year period expense was a reduction of an asset and did not result in a cash tax outlay.

Our 2019 estimated annual effective tax rate before discrete items is 12.9%. This estimated annual effective tax rate differs from the U.S. statutory rate of 21% primarily due to the deductions for percentage depletion in excess of cost depletion related to U.S. operations. The 2018 estimated annual effective tax rate before discrete items at March 31, 2018 was 0.1%. The rate in the comparable prior-year period was significantly lower due to the reversal of valuation allowance in the same period.

Loss from Discontinued Operations, net of tax

During the three months ended March 31, 2018, we had a loss of $70.9 millionprimarily due to the exit from our Asia Pacific Iron Ore operations, which was not repeated in 2019. Refer to NOTE 14 - DISCONTINUED OPERATIONS for further information.

EBITDA and Adjusted EBITDA

We evaluate performance based on EBITDA and Adjusted EBITDA, which are non-GAAP measures. These measures allow management and investors to focus on our ability to service our debt as well as illustrate how the business is performing.  Additionally, EBITDA and Adjusted EBITDA assist management and investors in their analysis and forecasting as these measures approximate the cash flows associated with operational earnings.

EBITDA increased $30.4 million for the three months endedMarch 31, 2019 on a consolidated basis from the comparable period in 2018. The favorable variance in EBITDA for the three months endedMarch 31, 2019 was driven primarily by the impact of the $63.1 million from Loss from discontinued operations, net of tax during the prior-year period that did not recur in 2019, partially offset by a decrease in sales margin of $30.6 million.

Adjusted EBITDA decreased $31.2 million for the three months endedMarch 31, 2019 from the comparable period in 2018, which was driven by a decrease in sales margin of $30.6 million compared to the prior-year period.

Liquidity, Cash Flows and Capital Resources

Our primary sources of liquidity are Cash and cash equivalents and cash generated from our operating and financing activities. Our capital allocation decision-making process is focused on returning capital to shareholders while maintaining the strength of our balance sheet and creating financial flexibility to manage through the inherent cyclical demand for our products and volatility in commodity prices. We are focused on maximizing the cash generation of our operations as well as reducing operating costs, aligning capital investments with our strategic priorities and the requirements of our business plan, including regulatory and permission-to-operate related projects.

During the first three months of 2019, we took action consistent with our capital allocation priorities of returning capital to shareholders, maintaining the strength of our balance sheet, improving our financial flexibility and executing on opportunities that will allow us to increase our long-term profitability. We have remained focused on protecting our business based on our actions to allocate capital to both sustaining our existing operations and our two major capital projects: the HBI plant in Toledo, Ohio and the upgrade to the Northshore plant to replace up to 3.5 million long tons of blast furnace pellet production with DR-grade pellet production.

39

Based on our outlook for the next 12 months, which is subject to continued changing demand from steelmakers that utilize our products and volatility in iron ore and domestic steel prices, we expect to generate cash from operations sufficient to meet the needs of our existing operations, service our debt obligations and fund our dividends.

Refer to “Outlook” for additional guidance regarding expected future results, including projections on sales volume and production.

The following discussion summarizes the significant activities impacting our cash flows during the three months ended March 31, 2019 and 2018 as well as expected impacts to our future cash flows over the next 12 months. Refer to the Statements of Unaudited Condensed Consolidated Cash Flows for additional information.

Operating Activities

Net cash used by operating activities was $111.2 million and $142.9 million for the three months ended March 31, 2019 and 2018, respectively. The incremental decrease in cash used by operating activities during the first quarter of 2019 primarily was due to prior year uses of cash by our discontinued operations.

Our U.S. cash and cash equivalents balance at March 31, 2019 was $428.7 million, or 99.7% of our consolidated total cash and cash equivalents balance of $430.2 million. Additionally, we had a cash balance at March 31, 2019 of $10.8 million classified as part of Other current assets in the Statements of Unaudited Condensed Consolidated Financial Position, which will be utilized to support the completion of our exit from Australia.

Investing Activities

Net cash used by investing activities was $125.6 million for the three months ended March 31, 2019, compared with $71.4 million for the comparable period in 2018. During the first three months of 2019, we had net cash outflows, including deposits, of approximately $90 million on development of the HBI production plant and approximately $20 million on the upgrades at Northshore Mine. Additionally, we spent approximately $13 million and $12 million on expenditures related to sustaining capital during the three months ended March 31, 2019 and 2018, respectively. Sustaining capital spend includes infrastructure, mobile equipment, environment, safety, fixed equipment, product quality and health.

We anticipate total cash used for capital expenditures, excluding amounts attributable to construction-related contingencies and capitalized interest, during the next 12 months to be approximately $530 million. Included within this estimate is approximately $100 million for sustaining capital, $400 million related to development of the HBI production plant and $30 million for upgrades at the Northshore plant. In total, including amounts spent to date, we expect to spend approximately $830 million on the HBI production plant and $90 million on the Northshore upgrades, exclusive of construction-related contingencies and capitalized interest, through 2020.

Financing Activities

Net cash used by financing activities in the first three months of 2019 was $157.8 million, compared to $7.0 million for the comparable period in 2018. Net cash used by financing activities during the first three months of 2019 primarily related to the repurchase of 11.5 million common shares for $124.3 million in the aggregate under the $200 million program authorized by our Board on November 24, 2018. On April 25, 2019, we announced Board authorization to repurchase up to an additional $100 million of common shares. Approximately $29 million of the original authorization remains available. When combined with the additional amount of share repurchase authorization, as of April 25, 2019, we have total share repurchase authorization remaining of up to approximately $129 million.

Additional uses of cash from financing activities included a cash dividend on our common shares of $14.8 million, and the repurchase of debt of $10.3 million. Uses of cash for financing activities during the first three months of 2018 primarily related to the repayment of lease liabilities.

We anticipate future uses of cash for financing activities during the next 12 months to include quarterly cash dividend payments of approximately $15 million per quarter and our final $44 million distribution of Empire partnership equity.

Cash and cash equivalents	$	430.2		$	823.2
Cash and cash equivalents from discontinued operations, included within other current assets	10.8			12.4
Total cash and cash equivalents	$	441.0		$	835.6
Available borrowing base on ABL Facility1	$	305.4		$	323.7
ABL Facility loans drawn	—			—
Letter of credit obligations and other commitments	(65.4		)	(55.0		)
Borrowing capacity available	$	240.0		$	268.7
1 The ABL Facility has a maximum borrowing base of $450 million, determined by applying customary advance rates to eligible accounts receivable, inventory and certain mobile equipment.

Our primary sources of funding are cash on hand, which totaled $441.0 million as of March 31, 2019, cash generated by our business, availability under the ABL Facility and other financing activities. The combination of cash and availability under the ABL Facility gives us $681.0 million in liquidity entering the second quarter of 2019, which is expected to be adequate to fund operations, letter of credit obligations, sustaining and expansion capital expenditures and other cash commitments for at least the next 12 months.

As of March 31, 2019, we were in compliance with the ABL Facility liquidity requirements and, therefore, the springing financial covenant requiring a minimum Fixed Charge Coverage Ratio of 1.0 to 1.0 was not applicable.

Off-Balance Sheet Arrangements

In the normal course of business, we are a party to certain arrangements that are not reflected on our Statements of Unaudited Condensed Consolidated Financial Position. These arrangements include minimum "take or pay" purchase commitments, such as minimum electric power demand charges, minimum coal, diesel and natural gas purchase commitments and minimum railroad transportation commitments. We also have financial instruments with off-balance sheet risk, such as bank letters of credit and bank guarantees.

Market Risks

We are subject to a variety of risks, including those caused by changes in commodity prices and interest rates. We have established policies and procedures to manage such risks; however, certain risks are beyond our control.

Pricing Risks

Commodity Price Risk

Our consolidated revenues include primarily the sale of a single product, iron ore pellets, in the North American market. Our financial results can vary significantly as a result of fluctuations in the market prices of iron ore, hot-rolled coil steel and iron ore pellet premiums. World market prices for these commodities have fluctuated historically and are affected by numerous factors beyond our control. The world market price that is most commonly utilized in our iron ore sales contracts is the Platts 62% Price, which can fluctuate widely due to numerous factors, such as global economic growth or contraction, change in demand for steel or changes in availability of supply.

41

Customer Supply Agreement

A supply agreement with one customer provides for supplemental revenue or refunds based on the average annual daily market price for hot-rolled coil steel at the time the iron ore product is consumed in the customer’s blast furnaces. At March 31, 2019, we had derivative assets of $106.4 million, representing the fair value of the pricing factors, based upon the amount of unconsumed long tons and an estimated average hot-rolled coil steel price for the period in which the iron ore is expected to be consumed in the customer's blast furnaces, subject to final pricing at a future date. We estimate that a $75 positive or negative change in the average daily market price for hot-rolled coil steel realized from the March 31, 2019 estimated price recorded would cause the fair value of the derivative instrument to increase or decrease by approximately $25.5 million, respectively, thereby impacting our consolidated revenues by the same amount. We have not entered into any hedging programs to mitigate the risk of adverse price fluctuations.

Volatile Energy and Fuel Costs

The cost of energy is an important factor affecting the production costs at our iron ore operations. Our operations consumed 4.0 million MMBtu’s of natural gas at an average delivered price of $4.46 per MMBtu during the first three months of 2019. Additionally, our operations consumed 4.7 million gallons of diesel fuel at an average delivered price of $2.14 per gallon during the first three months of 2019.    

Our strategy to address volatile natural gas and diesel rates includes improving efficiency in energy usage, identifying alternative providers and utilizing the lowest cost alternative fuels. We utilize a full-year hedging program to manage the price risk of natural gas and diesel at our Mining and Pelletizing mines. We will continue to monitor relevant energy markets for risk mitigation opportunities and may make additional forward purchases or employ other hedging instruments in the future as warranted and deemed appropriate by management. Based on the expected consumption for the remaining nine months of 2019, a 10% change in our current average year-to-date prices for both natural gas and diesel fuel would result in a change of approximately $8.8 million in our annual fuel and energy cost.

In the ordinary course of business, there may also be increases in prices relative to electricity costs at our mine sites. Specifically, Tilden has entered into large curtailable special contracts with Wisconsin Electric Power Company. Charges under those special contracts are subject to a power supply cost recovery mechanism that is based on variations in the utility's actual fuel and purchase power expenses.

Valuation of Other Long-Lived Assets

Long-lived assets are reviewed for impairment upon the occurrence of events or changes in circumstances that would indicate that the carrying value of the assets may not be recoverable. Such indicators may include: a significant decline in expected future cash flows; a sustained, significant decline in market pricing; a significant adverse change in legal or environmental factors or in the business climate; changes in estimates of our recoverable reserves; and unanticipated competition. Any adverse change in these factors could have a significant impact on the recoverability of our long-lived assets and could have a material impact on our consolidated statements of operations and statement of financial position.

A comparison of each asset group's carrying value to the estimated undiscounted net future cash flows expected to result from the use of the assets, including cost of disposition, is used to determine if an asset is recoverable. Projected future cash flows reflect management's best estimates of economic and market conditions over the projected period, including growth rates in revenues and costs, estimates of future expected changes in operating margins and capital expenditures. If the carrying value of the asset group is higher than its undiscounted net future cash flows, the asset group is measured at fair value and the difference is recorded as a reduction to the long-lived assets. We estimate fair value using a market approach, an income approach or a cost approach. As of March 31, 2019, no impairment factors were present that would indicate that the carrying value of our asset groups may not be recoverable; as a result, no impairment assessment was required.

Interest Rate Risk

Interest payable on our senior notes is at fixed rates. Interest payable under our ABL Facility is at a variable rate based upon the base rate plus the base rate margin depending on the excess availability. As of March 31, 2019, we had no amounts drawn on the ABL Facility.

Supply Concentration Risks

Many of our mines are dependent on one source each of electric power and natural gas. A significant interruption or change in service or rates from our energy suppliers could materially impact our production costs, margins and profitability.

Outlook

	2019 Outlook Summary
Per Long Ton Information	Mining and Pelletizing
Cost of goods sold rate	$74 - $79
Less:
Freight expense rate1	$8
Depreciation, depletion & amortization rate	$4
Cash cost of goods sold rate	$62 - $67
Sales volume (million long tons)2	20.0
Production volume (million long tons)	20.0
1 Freight has an offsetting amount in revenue and has no impact on sales margin.
2 This includes approximately 500,000 long tons of intercompany sales volumes to Cliffs' HBI facility.

Mining and Pelletizing Outlook (Long tons)

Based on the assumption that relevant pricing indices will average for the remainder of 2019 their respective year-to-date averages, including iron ore prices of $85 per metric ton, steel prices of $691 per short ton, and pellet premiums of $67 per metric ton, we would expect to realize Mining and Pelletizing revenue rates in the range of $108 to $113 per long ton, a $6 per long ton increase versus the comparable range provided last quarter. Assuming spot prices as of April 24, 2019, including an iron ore price of $94 per metric ton, a steel price of $676 per short ton, and a pellet premium of $66 per metric ton, will average these levels for the remainder of 2019, we would expect to realize Mining and Pelletizing revenue rates in the range of $111 to $116 per long ton for the full-year 2019.

For 2019, we maintained our full-year sales and production volume expectation of 20 million long tons. Our full-year 2019 Mining and Pelletizing cash cost of goods sold expectation is maintained at $62 to $67 per long ton.

Other Outlook

Our full-year 2019 SG&A expense expectation of $120 million is being maintained. We note that of the $120 million expectation, approximately $20 million is considered non-cash. Our full-year 2019 net interest expense expectation is maintained at $100 million. Full-year 2019 depreciation, depletion and amortization is expected to be approximately $80 million.

Based on refined projections, our 2019 effective tax rate is now expected to be approximately 12-14%.  However, due to our net operating loss position, our cash tax payments are still expected to be zero. We also expect to receive $117 million in cash tax refunds during the second quarter of 2019, which is earlier than previously expected.

Our total capital expenditures expectation of approximately $555 million (including capitalized interest) for the year 2019 is maintained.

Non-GAAP Reconciliation

We present cash cost of goods sold rate per long ton, which is a non-GAAP financial measure that management uses in evaluating operating performance. We believe our presentation of non-GAAP cash cost of goods sold is useful to investors because it excludes depreciation, depletion and amortization, which are non-cash, and freight, which has no impact on sales margin, thus providing a more accurate view of the cash outflows related to the sale of iron ore. The presentation of this measure is not intended to be considered in isolation from, as a substitute for, or as superior to, the financial information prepared and presented in accordance with GAAP. The presentation of this measure may be different from non-GAAP financial measures used by other companies. Below is a reconciliation in dollars of this non-GAAP financial measure to our consolidated financial statements.

	(In Millions)
	Three Months Ended March 31,

Item 3. Quantitative and Qualitative Disclosures About Market Risk

Information regarding our Market Risk is presented under the caption Market Risks, which is included inour Annual Report on Form 10-K for the year ended December 31, 2018, and in the Management's Discussion and Analysis section of this report.

Item 4. Controls and Procedures

We maintain disclosure controls and procedures that are designed to ensure that information required to be disclosed in our Exchange Act reports is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms, and that such information is accumulated and communicated to our management, including the Chief Executive Officer and the Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure based solely on the definition of “disclosure controls and procedures” in Rule 13a-15(e) promulgated under the Exchange Act. In designing and evaluating the disclosure controls and procedures, management recognized that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives, and management necessarily was required to apply its judgment in evaluating the cost-benefit relationship of possible controls and procedures.

As of the end of the period covered by this report, we carried out an evaluation under the supervision and with the participation of our management, including the Chief Executive Officer and the Chief Financial Officer, of the effectiveness of the design and operation of our disclosure controls and procedures. Based on the foregoing, the Chief Executive Officer and the Chief Financial Officer, concluded that our disclosure controls and procedures were effective.

There have been no changes in our internal control over financial reporting or in other factors that occurred during our last fiscal quarter that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

PART II - OTHER INFORMATION

Item 1. Legal Proceedings

Bluestone Litigation. On April 7, 2017, the Company was served with an Amended Complaint adding Cliffs, among others, as a defendant to a lawsuit brought by Bluestone Coal Corporation and Double-Bonus Mining Company against Pinnacle Mining Company, LLC and Target Drilling, Inc. in the U.S. District Court for the Southern District of West Virginia. The Amended Complaint alleges that the defendants deviated from plans authorized by plaintiffs and MSHA in the drilling of a borehole in 2013 and 2014 at the Pinnacle mine and through an inactive portion of plaintiffs’ mine. Plaintiffs further allege negligence and trespass in the drilling of the borehole and claim compensatory and punitive damages due to flooding. On October 3, 2018, the parties reached a settlement in full. We do not believe that our portion of the agreed-upon amount will have a material adverse impact on our business. The Court entered an order dismissing the case with prejudice subject to reopening on good cause shown within 90 days. However, on October 14, 2018, Mission Coal Company, LLC and ten of its affiliates, including Pinnacle Mining Company, LLC, filed a petition in the U.S. Bankruptcy Court for the Northern District of Alabama for relief under Chapter 11 of Title 11 of the U.S. Bankruptcy Code. We do not believe the bankruptcy petition will have a material adverse effect on our settlement. In light of the Mission Coal bankruptcy, the Court granted plaintiffs' motion to extend the deadline for potentially reopening the Bluestone case on good cause shown for an additional 120 days. As of April 12, 2019, the bankruptcy court lifted the automatic stay on the Bluestone litigation as it applied to non-debtor defendants, and Bluestone has moved to finalize the settlement with the non-debtor parties.

Item 4. Mine Safety Disclosures

We are committed to protecting the occupational health and well-being of each of our employees. Safety is one of our core values and we strive to ensure that safe production is the first priority for all employees. Our internal objective is to achieve zero injuries and incidents across the Company by focusing on proactively identifying needed prevention activities, establishing standards and evaluating performance to mitigate any potential loss to people, equipment, production and the environment. We have implemented intensive employee training that is geared toward maintaining a high level of awareness and knowledge of safety and health issues in the work environment through the development and coordination of requisite information, skills and attitudes. We believe that through these policies we have developed an effective safety management system.

Under the Dodd-Frank Act, each operator of a coal or other mine is required to include certain mine safety results within its periodic reports filed with the SEC. As required by the reporting requirements included in §1503(a) of the Dodd-Frank Act and Item 104 of Regulation S-K, the required mine safety results regarding certain mining safety and health matters for each of our mine locations that are covered under the scope of the Dodd-Frank Act are included in Exhibit 95 of Item 6.Exhibitsof this Quarterly Report on Form 10-Q.

Item 5. Other Information

Adoption of Form of Director and Officer Indemnification Agreement

On April 24, 2019, the Board of Directors approved a new form of Director and Officer Indemnification Agreement (the “Indemnification Agreement”) to be entered into by and between the Company and its directors and officers (each, an “Indemnitee”). The Indemnification Agreement provides that the Company will indemnify the Indemnitee against certain expenses and costs arising out of claims to which he or she becomes subject to in connection with his or her service to the Company. The Indemnification Agreement contains customary terms and conditions and establishes certain customary procedures and presumptions.

The Company intends to enter into a new Indemnification Agreement with each current member of the Board, the Company’s current executive officers and certain other Company officers. Each new Indemnification Agreement with a current director or officer will replace and supersede the prior indemnification agreement between the Company and such director or officer, if such director or officer was a party to a prior indemnification agreement.

The above description of the Indemnification Agreement does not purport to be complete and is qualified in its entirety by reference to the Indemnification Agreement, the form of which is filed as Exhibit 10.2 hereto and incorporated herein by reference.

of Section 409A, and the accumulated amounts shall be paid in a lump sum within ten (10) calendar days after the end of the six (6)-month period. If Employee dies during the six-month postponement period prior to the payment of such accumulated amounts, the payments which are deferred on account of Section 409A shall be paid to the personal representative of Employee’s estate within 60 calendar days after the date of Employee’s death. For purposes of this Agreement, each amount to be paid or benefit to be provided to Employee pursuant to this Agreement shall be construed as a separate identified payment for purposes of Section 409A. All reimbursements and in-kind benefits provided under the Agreement shall be made or provided in accordance with the requirements of Section 409A to the extent applicable, including, where applicable, the requirement that (i) any reimbursement is for expenses incurred during the period of time specified in this Agreement, (ii) the amount of expenses eligible for reimbursement, or in-kind benefits provided, during a calendar year may not affect the expenses eligible for reimbursement, or in kind benefits to be provided, in any other calendar year, (iii) the reimbursement of an eligible expense will be made no later than the last calendar day of the calendar year following the year in which the expense is incurred, and (iv) the right to reimbursement or in kind benefits is not subject to liquidation or exchange for another benefit.

EX-10.2

EXHIBIT 10.2

DIRECTOR AND OFFICER INDEMNIFICATION AGREEMENT

This Director and Officer Indemnification Agreement, dated as of ___________ ___, ____ (this “Agreement”), is made by and between Cleveland-Cliffs Inc., an Ohio corporation (the “Company”), and _______________________ (“Indemnitee”).

RECITALS:

A.    Section 1701.59 of the ORC provides that the business and affairs of a corporation shall be managed by or under the direction of its directors.

B.    By virtue of the managerial prerogatives vested in the directors and officers of an Ohio corporation, directors and officers act as fiduciaries of the corporation and its shareholders.

C.    Thus, it is critically important to the Company and its shareholders that the Company be able to attract and retain the most capable persons reasonably available to serve as directors and officers of the Company.

D.    In recognition of the need for corporations to be able to induce capable and responsible persons to accept and continue in positions in corporate management, Ohio law authorizes (and in some instances requires) corporations to indemnify their directors and officers, and further authorizes corporations to purchase and maintain insurance for the benefit of their directors and officers.

E.    Indemnification by a corporation serves the dual policies of (1) allowing corporate officials to resist unjustified lawsuits, secure in the knowledge that, if vindicated, the corporation will bear the expense of litigation and (2) encouraging capable women and men to serve as corporate directors and officers, secure in the knowledge that the corporation will absorb the costs of defending their honesty and integrity.

F.     Ohio law also authorizes a corporation to pay in advance of the final disposition of an action, suit or proceeding the expenses incurred by a director or officer in the defense thereof, and any such right to the advancement of expenses may be made separate and distinct from any right to indemnification and need not be subject to the satisfaction of any standard of conduct or otherwise affected by the merits of any claims against the director or officer.

G.    Lawsuits challenging the judgment and actions of directors and officers of corporations are frequent, and the high costs of defending those lawsuits, and the related threat to directors’ and officers’ personal assets made individuals less willing to undertake the responsibilities imposed on corporate directors and officers.

H.    Federal legislation and rules adopted by the Securities and Exchange Commission and the national securities exchanges have imposed additional disclosure and corporate governance obligations on directors and officers of public companies and have exposed such directors and officers to new and substantially broadened civil liabilities.

I.    These legislative and regulatory initiatives have also exposed directors and officers of public companies to a significantly greater risk of criminal proceedings, with attendant defense costs and potential criminal fines and penalties.

J.    Under Ohio law, a director’s and officer’s right to be reimbursed for the costs of defense of criminal actions does not depend upon the merits of the claims asserted against the director or officer and indemnification of the director or officer against criminal fines is permitted if the director or officer satisfies the applicable standard of conduct.

K.    Indemnitee is a director or officer of the Company and his or her willingness to serve in such capacity is predicated, in substantial part, upon the Company’s willingness to indemnify him or her in accordance with the principles reflected above, to the fullest extent permitted by the laws of the state of Ohio, and upon the other undertakings set forth in this Agreement.

L.    Therefore, in recognition of the need to provide Indemnitee with substantial and contractual protection against personal liability, in order to procure Indemnitee’s continued service as a director or officer of the Company

1

2019 04 Form of D&O Indemnification Agreement

and to enhance Indemnitee’s ability to serve the Company in an effective manner, and in order to provide such protection pursuant to express contract rights (intended to be enforceable irrespective of, among other things, any amendment to the Company’s articles of incorporation or regulations (collectively, the “Constituent Documents”), any change in the composition of the Company’s Board of Directors (the “Board”) or any change-in-control or business combination transaction relating to the Company), the Company wishes to provide in this Agreement for the indemnification of and the advancement of Expenses (as defined in Section 1(e)) to Indemnitee as set forth in this Agreement and for the continued coverage of Indemnitee under the Company’s directors’ and officers’ liability insurance policies.

M.    In light of the considerations referred to in the preceding recitals, it is the Company’s intention and desire that the provisions of this Agreement be construed liberally, subject to their express terms, to maximize the protections to be provided to Indemnitee hereunder.

AGREEMENT:

NOW, THEREFORE, in consideration of the mutual covenants contained herein and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereby agree as follows:

In addition to any service at the actual request of the Company, for purposes of this Agreement, Indemnitee shall be deemed to be serving or to have served at the request of the Company as a director, officer, employee, member, manager, trustee or agent of another entity or enterprise if Indemnitee is or was serving as a director, officer, employee, member, manager, trustee or agent of such entity or enterprise and (i) such entity or enterprise is or at the time of such service was a Controlled Affiliate, (ii) such entity or enterprise is or at the time of such service was an employee benefit plan (or related trust) sponsored or maintained by the Company or a Controlled Affiliate, or (iii) the Company or a Controlled Affiliate directly or indirectly caused or authorized Indemnitee to be nominated, elected, appointed, designated, employed, engaged or selected to serve in such capacity.

2.Indemnification Obligation. Subject to Section 8, the Company shall indemnify, defend and hold harmless Indemnitee, to the fullest extent permitted or required by the laws of the State of Ohio in effect on the date hereof or as such laws may from time to time hereafter be amended to increase the scope of such permitted or required indemnification, against any and all Indemnifiable Claims and Indemnifiable Losses; provided, however, that no repeal or amendment of any law of the State of Ohio shall in any way diminish or adversely affect the rights of Indemnitee pursuant to this Agreement in respect of any occurrence or matter arising prior to any such repeal or amendment.

3.Advancement of Expenses. Indemnitee shall have the right to advancement by the Company prior to the final disposition of any Indemnifiable Claim of any and all reasonableExpenses relating to, arising out of or

3

2019 04 Form of D&O Indemnification Agreement

resulting from any Indemnifiable Claim paid or incurred by Indemnitee or which Indemnitee determines are reasonably likely to be paid or incurred by Indemnitee. Indemnitee’s right to such advancement is not subject to the satisfaction of any standard of conduct and is not conditioned upon any prior determination that Indemnitee is entitled to indemnification under this Agreement with respect to the Indemnifiable Claim or the absence of any prior determination to the contrary. Without limiting the generality or effect of the foregoing, within five business days after any request by Indemnitee, the Company shall, in accordance with such request (but without duplication), (a) pay such Expenses on behalf of Indemnitee, (b) advance to Indemnitee funds in an amount sufficient to pay such Expenses, or (c) reimburse Indemnitee for such Expenses; provided that Indemnitee shall repay, without interest any amounts actually advanced to Indemnitee that, at the final disposition of the Indemnifiable Claim to which the advance related, were in excess of amounts paid or payable by Indemnitee in respect of Expenses relating to, arising out of or resulting from such Indemnifiable Claim. In connection with any such payment, advancement or reimbursement, Indemnitee shall execute and deliver to the Company an undertaking in the form attached hereto as Exhibit A (subject to Indemnitee filling in the blanks therein and selecting from among the bracketed alternatives therein), which need not be secured and shall be accepted by the Company without reference to Indemnitee’s ability to repay the Expenses. For purposes of obtaining payments of Expenses in advance of final disposition of any Indemnifiable Claim, Indemnitee shall submit to the Company an undertaking averring that Indemnitee has reasonably incurred or will reasonably incur actual Expenses in defending an Indemnifiable Claim. The undertaking need not be secured and the Company must accept the undertaking without reference to Indemnitee’s ability to repay the Expenses. Unless at the time of Indemnitee’s act or omission at issue, the Constituent Documents prohibit such advances by specific reference to ORC Section l701.13(E)(5)(a) or unless the only liability asserted against Indemnitee in the subject action, suit or proceeding is pursuant to ORC Section 1701.95, Indemnitee shall be eligible to execute Part A of the undertaking by which Indemnitee undertakes to: (i) repay such amount if it is proved by clear and convincing evidence in a court of competent jurisdiction that Indemnitee’s action or failure to act involved an act or omission undertaken with deliberate intent to cause injury to the Company or undertaken with reckless disregard for the best interests of the Company; and (ii) reasonably cooperate with the Company concerning the action, suit, proceeding or claim. In all cases, Indemnitee shall be eligible to execute Part B of the undertaking by which Indemnitee undertakes to repay such amount if it ultimately is determined that Indemnitee is not entitled to be indemnified by the Company under this Agreement or otherwise. In the event that Indemnitee is eligible to and does execute both Part A and Part B of the undertaking, the Expenses which are paid by the Company pursuant thereto shall be required to be repaid by Indemnitee only if Indemnitee is required to do so under the terms of both Part A and Part B of the undertaking. In no event shall Indemnitee’s right to the payment, advancement or reimbursement of Expenses pursuant to this Section 3 be conditioned upon any undertaking that is less favorable to Indemnitee than, or that is in addition to, the undertaking set forth in Exhibit A.

4.Indemnification for Additional Expenses. Without limiting the generality or effect of the foregoing, the Company shall indemnify and hold harmless Indemnitee against and, if requested by Indemnitee, shall reimburse Indemnitee for, or advance to Indemnitee, within five business days of such request, any and all reasonableExpenses paid or incurred by Indemnitee or which Indemnitee determines are reasonably likely to be paid or incurred by Indemnitee in connection with any Claim made, instituted or conducted by Indemnitee, in each case to the fullest extent permitted or required by the laws of the State of Ohio in effect on the date hereof or as such laws may from time to time hereafter be amended to increase the scope of such permitted or required indemnification, reimbursement or advancement of such Expenses, for (a) indemnification or payment, advancement or reimbursement of Expenses by the Company under any provision of this Agreement, or under any other agreement or provision of the Constituent Documents now or hereafter in effect relating to Indemnifiable Claims, and/or (b) recovery under any directors’ and officers’ liability insurance policies maintained by the Company; provided, however, that Indemnitee shall return, without interest, any such advance of Expenses (or portion thereof) which remains unspent at the final disposition of the Claim to which the advance related.

5.Contribution. To the fullest extent permissible under applicable law in effect on the date hereof or as such law may from time to time hereafter be amended to increase the scope of permitted or required indemnification, if the indemnification provided for in this Agreement is unavailable to Indemnitee for any reason whatsoever, the Company, in lieu of indemnifying Indemnitee, shall contribute to the payment of any and all Indemnifiable Claims or Indemnifiable Losses, in such proportion as is fair and reasonable in light of all of the circumstances in order to reflect (i) the relative benefits received by the Company and Indemnitee as a result of the event(s) and/or transaction(s) giving cause to such Indemnifiable Claim or Indemnifiable Loss and/or (ii) the relative fault of the Company (and its other directors, officers, employees and agents) and Indemnitee in connection with such event(s) and/or transaction(s); provided that such contribution shall not be required where it is determined, pursuant to a final disposition of such Indemnifiable Claim or Indemnifiable Loss in accordance with Section 8 or pursuant to the last sentence of Section 9(a), that Indemnitee is not entitled to indemnification by the Company with respect to such Indemnifiable Claim or Indemnifiable Loss. The Company will indemnify and hold harmless Indemnitee from any claim of contribution that

4

2019 04 Form of D&O Indemnification Agreement

may be brought by directors, officers, employees or other agents or representatives of the Company, other than Indemnitee, who may be jointly liable with Indemnitee.

6.Partial Indemnity. If Indemnitee is entitled under any provision of this Agreement to indemnification by the Company for some or a portion of any Indemnifiable Loss, but not for all of the total amount thereof, the Company shall indemnify Indemnitee for the portion thereof to which Indemnitee is entitled.

7.Procedure for Notification. To obtain indemnification under this Agreement in respect of an Indemnifiable Claim or Indemnifiable Loss, Indemnitee shall submit to the Company a written request therefor, including a brief description (based upon information then available to Indemnitee) of such Indemnifiable Claim or Indemnifiable Loss. If, at the time of the receipt of such request, the Company has directors’ and officers’ liability insurance in effect under which coverage for such Indemnifiable Claim or Indemnifiable Loss is potentially available, the Company shall give prompt written notice of such Indemnifiable Claim or Indemnifiable Loss to the applicable insurers in accordance with the procedures set forth in the applicable policies. The Company shall provide to Indemnitee a copy of such notice delivered to the applicable insurers, and copies of all subsequent correspondence between the Company and such insurers regarding the Indemnifiable Claim or Indemnifiable Loss, in each case substantially concurrently with the delivery or receipt thereof by the Company. If requested by Indemnitee, the Company shall use its best efforts when reasonable, at the Company’s expense, to enforce on behalf of and for the benefit of Indemnitee all rights (including rights to receive payment) that may exist under the applicable policies of insurance in relation to such Indemnifiable Claim or Indemnifiable Loss. The failure by Indemnitee to timely notify the Company of any Indemnifiable Claim or Indemnifiable Loss shall not relieve the Company from any liability hereunder unless, and only to the extent that, the Company did not otherwise learn of such Indemnifiable Claim or Indemnifiable Loss and such failure results in forfeiture by the Company of substantial defenses, rights or insurance coverage.

8.Determination of Right to Indemnification.

(a)To the extent that Indemnitee shall have been successful on the merits or otherwise in defense of any Indemnifiable Claim or any portion thereof or in defense of any issue or matter therein, including through a dismissal without prejudice, Indemnitee shall be indemnified against Indemnifiable Losses relating to, arising out of or resulting from such Indemnifiable Claim in accordance with Section 2 and no Standard of Conduct Determination (as defined in Section 8(b)) shall be required with respect to such Indemnifiable Claim.

(b)To the extent that the provisions of Section 8(a) are inapplicable to an Indemnifiable Claim that shall have been finally disposed of, any determination of whether Indemnitee has satisfied any applicable standard of conduct under Ohio law that is a legally required condition precedent to indemnification of Indemnitee hereunder against Indemnifiable Losses relating to, arising out of or resulting from such Indemnifiable Claim (a “Standard of Conduct Determination”) shall be made as follows: (i) by a majority vote of the Disinterested Directors, even if less than a quorum of the Board, (ii) if such Disinterested Directors so direct, by a majority vote of a committee of Disinterested Directors designated by a majority vote of all Disinterested Directors, or (iii) if there are no such Disinterested Directors or if Indemnitee so requests, by Independent Counsel, selected by the Indemnitee and approved by the Board (such approval not to be unreasonably withheld, delayed or conditioned), in a written opinion addressed to the Board, a copy of which shall be delivered to Indemnitee; provided, however, that if at the time of any Standard of Conduct Determination Indemnitee is neither a director nor an officer of the Company, such Standard of Conduct Determination may be made by or in the manner specified by the Board, any duly authorized committee of the Board or any duly authorized officer of the Company (unless Indemnitee requests that such Standard of Conduct Determination be made by Independent Counsel, in which case such Standard of Conduct Determination shall be made by Independent Counsel). Indemnitee will cooperate with the person or persons making such Standard of Conduct Determination, including providing to such person or persons, upon reasonable advance request, any documentation or information which is not privileged or otherwise protected from disclosure and which is reasonably available to Indemnitee and reasonably necessary to such determination. The Company shall indemnify and hold harmless Indemnitee against and, if requested by Indemnitee, shall reimburse Indemnitee for, or advance to Indemnitee, within five business days of such request, any and all reasonablecosts and expenses (including attorneys’ and experts’ fees and expenses) incurred by Indemnitee in so cooperating with the person or persons making such Standard of Conduct Determination.

(c)The Company shall use its reasonable efforts to cause any Standard of Conduct Determination required under Section 8(b) to be made as promptly as practicable. If (i) the person or persons empowered or selected under Section 8 to make the Standard of Conduct Determination shall not have made a determination within 30 days after the later of (A) receipt by the Company of written notice from Indemnitee advising the Company of the final disposition of the applicable Indemnifiable Claim (the date of such receipt being the “Notification Date”) and (B) the

5

2019 04 Form of D&O Indemnification Agreement

selection of an Independent Counsel, if such determination is to be made by Independent Counsel, and (ii) Indemnitee shall have fulfilled his or her obligations set forth in the second sentence of Section 8(b), then Indemnitee shall be deemed to have satisfied the applicable standard of conduct; provided that such 30-day period may be extended for a reasonable time, not to exceed an additional 30 days, if the person or persons making such determination in good faith requires such additional time for obtaining or evaluating any documentation or information relating thereto.

(d)If (i) Indemnitee shall be entitled to indemnification hereunder against any Indemnifiable Losses pursuant to Section 8(a), (ii) no determination of whether Indemnitee has satisfied any applicable standard of conduct under Ohio law is a legally required condition precedent to indemnification of Indemnitee hereunder against any Indemnifiable Losses, or (iii) Indemnitee has been determined or deemed pursuant to Section 8(b) or (c) to have satisfied any applicable standard of conduct under Ohio law which is a legally required condition precedent to indemnification of Indemnitee hereunder against any Indemnifiable Losses, then the Company shall pay to Indemnitee, within five business days after the later of (x) the Notification Date in respect of the Indemnifiable Claim or portion thereof to which such Indemnifiable Losses are related, out of which such Indemnifiable Losses arose or from which such Indemnifiable Losses resulted and (y) the earliest date on which the applicable criterion specified in clause (i), (ii) or (iii) above shall have been satisfied, an amount equal to the amount of such Indemnifiable Losses.

9.Presumption of Entitlement.

(a)In making a determination of whether Indemnitee has been successful on the merits or otherwise in defense of any Indemnifiable Claim or any portion thereof or in defense of any issue or matter therein, the Company acknowledges that a resolution, disposition or outcome short of dismissal or final judgment, including outcomes that permit Indemnitee to avoid expense, delay, embarrassment, injury to reputation, distraction, disruption or uncertainty, may constitute such success. In the event that any Indemnifiable Claim or any portion thereof or issue or matter therein is resolved or disposed of in any manner other than by adverse judgment against Indemnitee (including any resolution or disposition thereof by means of settlement with or without payment of money or other consideration), it shall be presumed that Indemnitee has been successful on the merits or otherwise in defense of such Indemnifiable Claim or portion thereof or issue or matter therein. The Company may overcome such presumption only by its adducing clear and convincing evidence to the contrary.

(b)In making any Standard of Conduct Determination, the person or persons making such determination shall presume that Indemnitee has satisfied the applicable standard of conduct, and the Company may overcome such presumption only by its adducing clear and convincing evidence to the contrary. The knowledge and/or action, or failure to act, of any other director, officer, employee, agent or representative of the Company will not be imputed to Indemnitee for purposes of any Standard of Conduct Determination. Any Standard of Conduct Determination that Indemnitee has satisfied the applicable standard of conduct shall be final and binding in all respects, including with respect to any litigation or other action or proceeding initiated by Indemnitee to enforce his or her rights hereunder. Any Standard of Conduct Determination that is adverse to Indemnitee may be challenged by Indemnitee in the state or federal courts in the State of Ohio. No determination by the Company (including by its directors or any Independent Counsel) that Indemnitee has not satisfied any applicable standard of conduct shall create a presumption that Indemnitee has not met any applicable standard of conduct.

(c)Without limiting the generality or effect of Section 9(b), (i) to the extent that any Indemnifiable Claim relates to any entity or enterprise (other than the Company) referred to in clause (i) of the first sentence of the definition of “Indemnifiable Claim,” Indemnitee shall be deemed to have satisfied the applicable standard of conduct if Indemnitee acted in good faith and in a manner Indemnitee reasonably believed to be in or not opposed to the interests of such entity or enterprise (or the owners or beneficiaries thereof, including in the case of any employee benefit plan the participants and beneficiaries thereof) and, with respect to any criminal action or proceeding, had no reasonable cause to believe that his or her conduct was unlawful, and (ii) in all cases, any belief of Indemnitee that is based on the records or books of account of the Company, including financial statements, or on information supplied to Indemnitee by the directors or officers of the Company in the course of their duties, or on the advice of legal counsel for the Company, the Board, any committee of the Board or any director, or on information or records given or reports made to the Company, the Board, any committee of the Board or any director by an independent certified public accountant or by an appraiser or other expert selected by or on behalf of the Company, the Board, any committee of the Board or any director shall be deemed to be reasonable.

10.No Adverse Presumption. For purposes of this Agreement, the termination of any Claim by judgment, order, settlement (whether with or without court approval) or conviction, or upon a plea of nolo contendere or its

6

2019 04 Form of D&O Indemnification Agreement

equivalent, will not create a presumption that Indemnitee did not meet any applicable standard of conduct or that indemnification hereunder is otherwise not permitted.

11.Non‑Exclusivity. The rights of Indemnitee hereunder will be in addition to any other rights Indemnitee may have against the Company under the Constituent Documents, or the substantive laws of the Company’s jurisdiction of incorporation, any other contract or otherwise (collectively, “Other Indemnity Provisions”); provided, however, that (a) to the extent that Indemnitee otherwise would have any greater right to indemnification under any Other Indemnity Provision, Indemnitee will be deemed to have such greater right hereunder and (b) to the extent that any change is made to any Other Indemnity Provision which permits any greater right to indemnification than that provided under this Agreement as of the date hereof, Indemnitee will be deemed to have such greater right hereunder. The Company will not adopt any amendment to any of the Constituent Documents the effect of which would be to deny, diminish or encumber Indemnitee’s right to indemnification under this Agreement or any Other Indemnity Provision.

12.Liability Insurance and Funding. For the duration of Indemnitee’s service as a director and/or officer of the Company, and thereafter for so long as Indemnitee shall be subject to any pending or possible Indemnifiable Claim, the Company shall use reasonable efforts (taking into account the scope and amount of coverage available relative to the cost thereof and other relevant factors, including changes in the Company’s business and/or industry) to cause to be maintained in effect policies of directors’ and officers’ liability insurance providing coverage for current and former directors and/or officers of the Company. Upon request, the Company shall provide Indemnitee with a copy of all directors’ and officers’ liability insurance applications, binders, policies, declarations and endorsements. The Company shall not discontinue or significantly reduce the scope or amount of coverage from one policy period to the next without the prior approval thereof by a majority vote of the Incumbent Directors, even if less than a quorum. In all policies of directors’ and officers’ liability insurance obtained by the Company, Indemnitee shall be included as an insured in such a manner as to provide Indemnitee the same rights and benefits, subject to the same limitations, as are accorded to the Company’s directors and officers most favorably insured by such policy. The Company may, but shall not be required to, create a trust fund, grant a security interest or use other means, including a letter of credit, to ensure the payment of such amounts as may be necessary to satisfy its obligations to indemnify and advance expenses pursuant to this Agreement.

13.Subrogation. In the event of payment under this Agreement, the Company shall be subrogated to the extent of such payment to all of the related rights of recovery of Indemnitee against other persons or entities (other than Indemnitee’s successors), including any entity or enterprise referred to in clause (i) of the definition of “Indemnifiable Claim” in Section 1(g). Indemnitee shall execute all papers reasonably required to evidence such rights (all of Indemnitee’s reasonable Expenses, including attorneys’ fees and charges, related thereto to be reimbursed by or, at the option of Indemnitee, advanced by the Company).

14.No Duplication of Payments. The Company shall not be liable under this Agreement to make any payment to Indemnitee in respect of any Indemnifiable Losses to the extent Indemnitee has otherwise actually received and is entitled to retain payment (net of any Expenses incurred in connection therewith and any repayment by Indemnitee made with respect thereto) under any insurance policy, the Constituent Documents and Other Indemnity Provisions or otherwise (including from any entity or enterprise referred to in clause (i) of the definition of “Indemnifiable Claim” in Section 1(g)) in respect of such Indemnifiable Losses otherwise indemnifiable hereunder.

15.Defense of Claims. Except for any Indemnifiable Claim asserted by or in the right of the Company (as to which Indemnitee shall be entitled to exclusively control the defense), the Company shall be entitled to participate in the defense of any Indemnifiable Claim or to assume the defense thereof, with counsel reasonably satisfactory to Indemnitee. The Company’s participation in the defense of any Indemnifiable Claim of which the Company has not assumed the defense will not in any manner affect the rights of Indemnitee under this Agreement, including Indemnitee’s right to control the defense of such Indemnifiable Claims. With respect to the period (if any) commencing at the time at which the Company notifies Indemnitee that the Company has assumed the defense of any Indemnifiable Claim and continuing for so long as the Company shall be using its reasonable best efforts to provide an effective defense of such Indemnifiable Claim, the Company shall have the right to control the defense of such Indemnifiable Claim and shall have no obligation under this Agreement in respect of any attorneys’ or experts’ fees or expenses or any other costs or expensespaid or incurred by Indemnitee in connection with defending such Indemnifiable Claim (other than such costs and expenses paid or incurred by Indemnitee in connection with any cooperation in the Company’s defense of such Indemnifiable Claim or other action undertaken by Indemnitee at the request of the Company or with the consent of the Company (which consent shall not be unreasonably withheld, conditioned or delayed)); provided that if Indemnitee believes, after consultation with counsel selected by Indemnitee, that (a) the use of counsel chosen by the Company to represent Indemnitee would present such counsel with an actual or potential conflict, (b) the named

7

2019 04 Form of D&O Indemnification Agreement

parties in any such Indemnifiable Claim (including any impleaded parties) include both the Company and Indemnitee and Indemnitee shall conclude that there may be one or more legal defenses available to him or her that are different from or in addition to those available to the Company, or (c) any such representation by such counsel chosen by the Company would be precluded under the applicable standards of professional conduct then prevailing, then Indemnitee shall be entitled to retain and use the services of separate counsel (but not more than one law firm plus, if applicable, local counsel in respect of any particular Indemnifiable Claim) at the Company’s expense. Nothing in this Agreement shall limit Indemnitee’s right to retain or use his or her own counsel at his or her own expense in connection with any Indemnifiable Claim; provided that in all events Indemnitee shall not unreasonably interfere with the conduct of the defense by the Company of any Indemnifiable Claim that the Company shall have assumed and of which the Company shall be using its reasonable best efforts to provide an effective defense. The Company shall not be liable to Indemnitee under this Agreement for any amounts paid in settlement of any threatened or pending Indemnifiable Claim effected without the Company’s prior written consent. The Company shall not, without the prior written consent of Indemnitee, effect any settlement of any threatened or pending Indemnifiable Claim to which Indemnitee is, or could have been, a party unless such settlement solely involves the payment of money and includes a complete and unconditional release of Indemnitee from all liability on any claims that are the subject matter of such Indemnifiable Claim. Neither the Company nor Indemnitee shall unreasonably withhold, condition or delay its consent to any proposed settlement; provided that Indemnitee may withhold consent to any settlement that does not provide a complete and unconditional release of Indemnitee.

16.Successors and Binding Agreement.

(a)The Company shall require any successor (whether direct or indirect, by purchase, merger, consolidation, reorganization or otherwise) to all or substantially all of the business or assets of the Company, by agreement in form and substance satisfactory to Indemnitee and his or her counsel, expressly to assume and agree to perform this Agreement in the same manner and to the same extent the Company would be required to perform if no such succession had taken place. This Agreement shall be binding upon and inure to the benefit of the Company and any successor to the Company, including any person acquiring directly or indirectly all or substantially all of the business or assets of the Company whether by purchase, merger, consolidation, reorganization or otherwise (and such successor will thereafter be deemed the “Company” for purposes of this Agreement), but shall not otherwise be assignable or delegatable by the Company.

(b)This Agreement shall inure to the benefit of and be enforceable by Indemnitee’s personal or legal representatives, executors, administrators, heirs, distributees, trustees, legatees and other successors.

(c)This Agreement is personal in nature and neither of the parties hereto shall, without the consent of the other, assign or delegate this Agreement or any rights or obligations hereunder except as expressly provided in Sections 16(a) and 16(b). Without limiting the generality or effect of the foregoing, Indemnitee’s right to receive payments hereunder shall not be assignable, whether by pledge, creation of a security interest or otherwise, other than by a transfer by Indemnitee’s will or by the laws of descent and distribution, and, in the event of any attempted assignment or transfer contrary to this Section 16(c), the Company shall have no liability to pay any amount so attempted to be assigned or transferred.

17.Notices. For all purposes of this Agreement, all communications, including notices, consents, requests or approvals, required or permitted to be given hereunder shall be in writing and shall be deemed to have been duly given when hand delivered or dispatched by electronic facsimile or email transmission (with receipt thereof orally confirmed), or five business days after having been mailed by United States registered or certified mail, return receipt requested, postage prepaid or one business day after having been sent for next‑day delivery by a nationally recognized overnight courier service, addressed to the Company (to the attention of the Secretary of the Company) and to Indemnitee at the applicable address shown on the signature page hereto, or to such other address as any party hereto may have furnished to the other in writing and in accordance herewith, except that notices of changes of address will be effective only upon receipt.

18.Governing Law. The validity, interpretation, construction and performance of this Agreement shall be governed by and construed in accordance with the substantive laws of the State of Ohio, without giving effect to the principles of conflict of laws of such State. The Company and Indemnitee each hereby irrevocably consent to the jurisdiction of the state and federal courts located in State of Ohio for all purposes in connection with any action or proceeding which arises out of or relates to this Agreement and agree that any action instituted under this Agreement shall be brought only in the state and federal courts located in State of Ohio.

19.Validity. If any provision of this Agreement or the application of any provision hereof to any person or circumstance is held invalid, unenforceable or otherwise illegal, the remainder of this Agreement and the application of such provision to any other person or circumstance shall not be affected, and the provision so held to be invalid, unenforceable or otherwise illegal shall be reformed to the extent, and only to the extent, necessary to make it enforceable, valid or legal. In the event that any court or other adjudicative body shall decline to reform any provision of this Agreement held to be invalid, unenforceable or otherwise illegal as contemplated by the immediately preceding sentence, the parties thereto shall take all such action as may be necessary or appropriate to replace the provision so held to be invalid, unenforceable or otherwise illegal with one or more alternative provisions that effectuate the purpose and intent of the original provisions of this Agreement as fully as possible without being invalid, unenforceable or otherwise illegal. This Agreement shall replace and supersede the indemnification agreement in effect between Indemnitee and the Company immediately prior to the execution and delivery of this Agreement by Indemnitee and the Company.

20.Miscellaneous. No provision of this Agreement may be waived, modified or discharged unless such waiver, modification or discharge is agreed to in writing signed by Indemnitee and the Company. No waiver by either party hereto at any time of any breach by the other party hereto or compliance with any condition or provision of this Agreement to be performed by such other party shall be deemed a waiver of similar or dissimilar provisions or conditions at the same or at any prior or subsequent time. No agreements or representations, oral or otherwise, expressed or implied with respect to the subject matter hereof have been made by either party hereto that are not set forth expressly in this Agreement.

21.Legal Fees and Expenses; Interest.

(a)It is the intent of the Company that Indemnitee not be required to incur legal fees and or other Expenses associated with the interpretation, enforcement or defense of Indemnitee’s rights under this Agreement by litigation or otherwise because the cost and expense thereof would substantially detract from the benefits intended to be extended to Indemnitee hereunder. Accordingly, without limiting the generality or effect of any other provision hereof, if it should appear to Indemnitee that the Company has failed to comply with any of its obligations under this Agreement (including its obligations under Section 3) or in the event that the Company or any other person takes or threatens to take any action to declare this Agreement void or unenforceable, or institutes any litigation or other action or proceeding designed to deny, or to recover from, Indemnitee the benefits provided or intended to be provided to Indemnitee hereunder, the Company irrevocably authorizes Indemnitee from time to time to retain counsel of Indemnitee’s choice, at the expense of the Company as hereafter provided, to advise and represent Indemnitee in connection with any such interpretation, enforcement or defense, including the initiation or defense of any litigation or other legal action, whether by or against the Company or any director, officer, shareholder or other person affiliated with the Company, in any jurisdiction. Notwithstanding any existing or prior attorney-client relationship between the Company and such counsel, the Company irrevocably consents to Indemnitee’s entering into an attorney-client relationship with such counsel, and in that connection the Company and Indemnitee agree that a confidential relationship shall exist between Indemnitee and such counsel. The Company will pay and be solely financially responsible for any and all reasonableattorneys’ and related fees and expenses incurred by Indemnitee in connection with any of the foregoing to the fullest extent permitted or required by the laws of the State of Ohio in effect on the date hereof or as such laws may from time to time hereafter be amended to increase the scope of such permitted or required payment of such fees and expenses.

(b)Any amount due to Indemnitee under this Agreement that is not paid by the Company by the date on which it is due will accrue interest at the maximum legal rate under Ohio law from the date on which such amount is due to the date on which such amount is paid to Indemnitee.

22.Certain Interpretive Matters. Unless the context of this Agreement otherwise requires, (a) “it” or “its” or words of any gender include each other gender, (b) words using the singular or plural number also include the plural or singular number, respectively, (c) the terms “hereof,” “herein,” “hereby” and derivative or similar words refer to this entire Agreement, (d) the terms “Article”, “Section” or “Exhibit” refer to the specified Section or Exhibit of or to this Agreement, (e) the terms “include,” “includes” and “including” will be deemed to be followed by the words “without limitation” (whether or not so expressed), and (f) the word “or” is disjunctive but not exclusive. Whenever this Agreement refers to a number of days, such number will refer to calendar days unless business days are specified and whenever action must be taken (including the giving of notice or the delivery of documents) under this Agreement during a certain period of time or by a particular date that ends or occurs on a non-business day, then such period or date will be extended until the immediately following business day. As used herein, “business day” means any day other than Saturday, Sunday or a United States federal holiday.

Exhibit 95

Mine Safety Disclosures

The operation of our mines located in the United States is subject to regulation by MSHA under the FMSH Act. MSHA inspects these mines on a regular basis and issues various citations and orders when it believes a violation has occurred under the FMSH Act. We present information below regarding certain mining safety and health citations that MSHA has issued with respect to our mining operations. In evaluating this information, consideration should be given to factors such as: (i) the number of citations and orders will vary depending on the size of the mine; (ii) the number of citations issued will vary from inspector to inspector and mine to mine, and (iii) citations and orders can be contested and appealed and, in that process, are often reduced in severity and amount, and are sometimes dismissed.

Under the Dodd-Frank Act, each operator of a coal or other mine is required to include certain mine safety results within its periodic reports filed with the SEC. As required by the reporting requirements included in §1503(a) of the Dodd-Frank Act, we present the following items regarding certain mining safety and health matters, for the period presented, for each of our mine locations that are covered under the scope of the Dodd-Frank Act:

(A) The total number of violations of mandatory health or safety standards that could significantly and substantially contribute to the cause and effect of a coal or other mine safety or health hazard under section 104 of the FMSH Act (30 U.S.C. 814) for which the operator received a citation from MSHA;

(B) The total number of orders issued under section 104(b) of the FMSH Act (30 U.S.C. 814(b));

(C) The total number of citations and orders for unwarrantable failure of the mine operator to comply with mandatory health or safety standards under section 104(d) of the FMSH Act (30 U.S.C. 814(d));

(D) The total number of imminent danger orders issued under section 107(a) of the FMSH Act (30 U.S.C. 817(a));

(E) The total dollar value of proposed assessments from MSHA under the FMSH Act (30 U.S.C. 801 et seq.);

(F) Legal actions pending before the Federal Mine Safety and Health Review Commission involving such coal or other mine as of the last day of the period;

(G) Legal actions initiated before the Federal Mine Safety and Health Review Commission involving such coal or other mine during the period; and

(H) Legal actions resolved before the Federal Mine Safety and Health Review Commission involving such coal or other mine during the period.

During the three months ended March 31, 2019, our U.S. mine locations did not receive any flagrant violations under section 110(b)(2) of the FMSH Act or any written notices of a pattern of violations, or the potential to have such a pattern of violations, under section 104(e) of the FMSH Act. In addition, there were no mining-related fatalities at any of our U.S. mine locations during this same period.

Following is a summary of the information listed above for the three months ended March 31, 2019:

BASIS OF PRESENTATION AND SIGNIFICANT ACCOUNTING POLICIES

NOTE 1 - BASIS OF PRESENTATION AND SIGNIFICANT ACCOUNTING POLICIES

The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with SEC rules and regulations and, in the opinion of management, include all adjustments (consisting of normal recurring adjustments) necessary to present fairly the financial position, results of operations, comprehensive loss and cash flows for the periods presented. The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Management bases its estimates on various assumptions and historical experience, which are believed to be reasonable; however, due to the inherent nature of estimates, actual results may differ significantly due to changed conditions or assumptions. The results of operations for the three months endedMarch 31, 2019 are not necessarily indicative of results to be expected for the year ending December 31, 2019 or any other future period. These unaudited condensed consolidated financial statements should be read in conjunction with the financial statements and notes included in our Annual Report on Form 10-K for the year ended December 31, 2018.

As more fully described in the Form 10-K for the year ended December 31, 2018, in 2018 we committed to a course of action leading to the permanent closure of the Asia Pacific Iron Ore mining operations and, as planned, completed our final shipment in June 2018. Factors considered in this decision included increasingly discounted prices for lower-iron-content ore and the quality of the remaining iron ore reserves.

During 2018, we sold all of the assets of our Asia Pacific Iron Ore business through a series of sales to third parties.As a result of our planned exit, management determined that our Asia Pacific Iron Ore operating segment met the criteria to be classified as held for sale and a discontinued operation under ASC Topic 205, Presentation of Financial Statements. As such, all Asia Pacific Iron Ore operating segment results are classified within discontinued operations. Refer to NOTE 14 - DISCONTINUED OPERATIONS for further information.

We have two reportable segments - the Mining and Pelletizing segment and the Metallics segment. Unless otherwise noted, discussion of our business and results of operations in this Quarterly Report on Form 10-Q refers to our continuing operations.

Basis of Consolidation

The unaudited condensed consolidated financial statements include our accounts and the accounts of our wholly-owned subsidiaries, including the following operations as of March 31, 2019:

Name	Location	Business Segment	Status of Operations
Northshore	Minnesota	Mining and Pelletizing	Active
United Taconite	Minnesota	Mining and Pelletizing	Active
Tilden	Michigan	Mining and Pelletizing	Active
Empire	Michigan	Mining and Pelletizing	Indefinitely Idled
Toledo HBI	Ohio	Metallics	Construction Stage

Intercompany transactions and balances are eliminated upon consolidation.

Equity Method Investments

Our 23% ownership interest in Hibbing is recorded as an equity method investment. As of March 31, 2019 and December 31, 2018, our investment in Hibbing was $10.8 million and $15.4 million, respectively, classified as Other liabilities in the Statements of Unaudited Condensed Consolidated Financial Position.

Significant Accounting Policies

A detailed description of our significant accounting policies can be found in the audited financial statements for the fiscal year ended December 31, 2018 included in our Annual Report on Form 10-K filed with the SEC. There have been no material changes in our significant accounting policies and estimates from those disclosed therein.

NEW ACCOUNTING STANDARDS

New Accounting Pronouncements and Changes in Accounting Principles [Abstract]

NEW ACCOUNTING STANDARDS

NOTE 2 - NEW ACCOUNTING STANDARDS

Issued and Adopted

In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842). The new standard requires lessees to recognize a right-of-use asset and a lease liability on the balance sheet for all leases except for short-term leases. For lessees, leases will be classified as either operating or finance leases in the Statements of Unaudited Condensed Consolidated Operations. We adopted this standard on its effective date of January 1, 2019 using the optional alternative approach, which requires application of the new guidance at the beginning of the standard's effective date. Adoption of the updated standard did not have a material effect on our consolidated financial statements.

Issued and Not Effective

In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments–Credit Losses (Topic 326), which introduces a new accounting model, CECL. CECL requires earlier recognition of credit losses, while also providing additional transparency about credit risk. The CECL model utilizes a lifetime expected credit loss measurement objective for the recognition of credit losses for receivables at the time the financial asset is originated or acquired. The expected credit losses are adjusted each period for changes in expected lifetime credit losses. We plan to adopt this standard on its effective date of January 1, 2020, and are currently evaluating the impact of this standard on our financial statements.

Segment Reporting [Abstract]

Segment Reporting Disclosure [Text Block]

NOTE 3 - SEGMENT REPORTING

In alignment with our strategic goals, our Company’s continuing operations are organized and managed in two operating segments according to our differentiated products. Our Mining and Pelletizing segment is a major supplier of iron ore pellets to the North American steel industry from our mines and pellet plants located in Michigan and Minnesota. In our Metallics segment, we are currently constructing an HBI production plant in Toledo, Ohio. We expect to complete construction and begin production in 2020.

We evaluate performance based on sales margin, defined as revenues less cost of goods sold identifiable to each segment. Additionally, we evaluate performance on a segment basis, as well as a consolidated basis, based on EBITDA and Adjusted EBITDA. These measures allow management and investors to focus on our ability to service our debt as well as illustrate how the business is performing.  Additionally, EBITDA and Adjusted EBITDA assist management and investors in their analysis and forecasting as these measures approximate the cash flows associated with operational earnings.

The following tables present a summary of our reportable segments including a reconciliation of segment sales margin to Income (loss) from Continuing Operations Before Income Taxes and a reconciliation of Net loss to EBITDA and Adjusted EBITDA:

REVENUE

Revenue from Contract with Customer [Abstract]

Revenue from Contract with Customer [Text Block]

NOTE 4 - REVENUE

We sell primarily a single product, iron ore pellets, in the North American market. Revenue is recognized generally when iron ore is delivered to our customers. Revenue is measured at the point that control transfers and represents the amount of consideration we expect to receive in exchange for transferring goods. We offer standard payment terms to our customers, generally requiring settlement within 30 days.

We enter into supply contracts of varying lengths to provide customers iron ore pellets to use in their blast furnaces. Blast furnaces run continuously with a constant feed of iron ore and, once shut down, cannot easily be restarted. As a result, we ship iron ore in large quantities for storage and use by customers at a later date. Customers do not simultaneously receive and consume the iron ore. Based on our assessment of the factors that indicate the pattern of satisfaction, we transfer control of the iron ore at a point in time upon shipment or delivery of the product. The customer is able to direct the use of, and obtain substantially all of the benefits from, the product at the time the product is delivered.

Most of our customer supply agreements specify a provisional price, which is used for initial billing and cash collection. Revenue recorded in accordance with Topic 606 is calculated using the expected revenue rate at the point when control transfers. The final settlement includes market inputs for a specified period of time, which may vary by customer, but typically include one or more of the following published rates: Platts 62% Price, Atlantic Basin pellet premiums, Platts international indexed freight rates and changes in specified Producer Price Indices, including industrial commodities, fuel and steel. Changes in the expected revenue rate from the date control transfers through final settlement of contract terms is recorded in accordance with Topic 815. Refer to NOTE 13 - DERIVATIVE INSTRUMENTS for further information on how our estimated and final revenue rates are determined.

A supply agreement with a customer provides for supplemental revenue or refunds based on the average annual daily market price for hot-rolled coil steel in the year the iron ore is consumed in the customer’s blast furnaces. As control transfers prior to consumption, the supplemental revenue is recorded in accordance with ASC Topic 815. Refer to NOTE 13 - DERIVATIVE INSTRUMENTS for further information on supplemental revenue or refunds.

Included within Revenues from product sales and services is derivative revenue related to Topic 815 of $5.5 million and $43.8 million, for three months endedMarch 31, 2019 and 2018, respectively.

Deferred Revenue

The table below summarizes our deferred revenue balances:

	(In Millions)
	Deferred Revenue (Current)					Deferred Revenue (Long-Term)
	2019			2018		2019		2018
Opening balance as of January 1	$	21.0		$	23.8	$	38.5	$	51.4
Closing balance as of March 31	18.1			31.0		38.5		51.4
Increase (decrease)	$	(2.9	)	$	7.2	$	—	$	—

The terms of one of our pellet supply agreements required supplemental payments to be paid by the customer during the period 2009 through 2012. Installment amounts received under this arrangement in excess of sales were classified as Other current liabilities and Other liabilities in the Statements of Unaudited Condensed Consolidated Financial Position upon receipt of payment. Revenue is recognized over the life of the supply agreement, which extends until 2022, in equal annual installments. As of March 31, 2019 and December 31, 2018, installment amounts received in excess of sales totaled $51.4 million related to this agreement. As of March 31, 2019 and December 31, 2018, deferred revenue of $12.9 million was recorded in Other current liabilities and $38.5 million was recorded as long-term in Other liabilities in the Statements of Unaudited Condensed Consolidated Financial Position, related to this agreement.

Due to the payment terms and the timing of cash receipts near a period end, cash receipts can exceed shipments for certain customers. Revenue recognized on these transactions totaling $5.3 million and $8.2 million was deferred and included in Other current liabilities in the Statements of Unaudited Condensed Consolidated Financial Position as of March 31, 2019 and December 31, 2018, respectively.

Financial assets classified in Level 1 included money market funds. The valuation of these instruments is based upon unadjusted quoted prices for identical assets in active markets.

The valuation of financial assets and liabilities classified in Level 2 is determined using a market approach based upon quoted prices for similar assets and liabilities in active markets, or other inputs that are observable. Level 2 assets include commercial paper, certificates of deposit and commodity hedge contracts. Level 2 liabilities include commodity hedge contracts.

The Level 3 assets and liabilities include derivative assets that consist of freestanding derivative instruments related to a certain supply agreement and derivative assets and liabilities related to certain provisional pricing arrangements with our customers.

The supply agreement included in our Level 3 assets contains provisions for supplemental revenue or refunds based on the average annual daily market price for hot-rolled coil steel in the year the iron ore product is consumed in the customer’s blast furnaces. We account for these provisions as derivative instruments at the time of sale and adjust the derivative instruments to fair value through Product revenues each reporting period until the product is consumed and the amounts are settled. We had assets of $106.4 million and $89.3 million at March 31, 2019 and December 31, 2018, respectively, related to this supply agreement.

The provisional pricing arrangements included in our Level 3 assets/liabilities specify provisional price calculations, where the pricing mechanisms generally are based on market pricing, with the final revenue rate to be based on market inputs at a specified point in time in the future, per the terms of the supply agreements. The difference between the estimated final revenue rate at the date of sale and the estimated final revenue rate at the measurement date is characterized as a derivative and is required to be accounted for separately once the revenue has been recognized. The derivative instruments are adjusted to fair value through Product revenues each reporting period based upon current market data and forward-looking estimates provided by management until the final revenue rates are determined. We had assets of $0.3 million and liabilities of $9.8 million related to provisional pricing arrangements at March 31, 2019 compared to assets of $2.1 million related to provisional pricing arrangements at December 31, 2018.

The following table illustrates information about quantitative inputs and assumptions for the assets and liabilities categorized in Level 3 of the fair value hierarchy:

PENSIONS AND OTHER POSTRETIREMENT BENEFITS

NOTE 9 - PENSIONS AND OTHER POSTRETIREMENT BENEFITS

We offer defined benefit pension plans, defined contribution pension plans and OPEB plans, primarily consisting of retiree healthcare benefits, to most employees as part of a total compensation and benefits program. The defined benefit pension plans are noncontributory and benefits generally are based on a minimum formula or employees’ years of service and average earnings for a defined period prior to retirement.

The following are the components of defined benefit pension and OPEB costs:

Stock Compensation Plans

NOTE 10 - STOCK COMPENSATION PLANS

Employees’ Plans

On February 19, 2019, the Compensation Committee approved grants under the A&R 2015 Equity Plan to certain officers and employees for the 2019 to 2021 performance period. Shares granted under the awards consisted of 0.6 million restricted stock units and 0.6 million performance shares.

Restricted stock units granted during 2019 are subject to continued employment, are retention based and are payable in common shares. The outstanding restricted stock units that were granted in 2019 cliff vest on December 31, 2021.

Performance shares are subject to continued employment, and each performance share, if earned, entitles the holder to be paid out in common shares. Performance is measured on the basis of relative TSR for the period of January 1, 2019 to December 31, 2021 and measured against the constituents of the SPDR S&P Metals and Mining ETF Index at the beginning of the relevant performance period. The final payouts for the outstanding performance period grants will vary from zero to 200% of the original grant depending on whether and to what extent the Company achieves certain objectives and performance goals as established by the Compensation Committee.

Determination of Fair Value

The fair value of each performance share grant is estimated on the date of grant using a Monte Carlo simulation to forecast relative TSR performance. A correlation matrix of historic and projected stock prices was developed for both the Company and our predetermined peer group of mining and metals companies. The fair value assumes that the objective will be achieved.

The expected term of the grant represents the time from the grant date to the end of the service period. We estimate the volatility of our common shares and that of the peer group of mining and metals companies using daily price intervals for all companies. The risk-free interest rate is the rate at the grant date on zero-coupon government bonds with a term commensurate with the remaining life of the performance period.

The following assumptions were utilized to estimate the fair value for the 2019 performance share grant:

Grant Date	Grant Date Market Price		Average Expected Term (Years)	Expected Volatility	Risk-Free Interest Rate	Dividend Yield	Fair Value		Fair Value (Percent of Grant Date Market Price)

Income Taxes

NOTE 11 - INCOME TAXES

Our 2019 estimated annual effective tax rate before discrete items is 12.9%. The estimated annual effective tax rate differs from the U.S. statutory rate of 21.0% primarily due to the deductions for percentage depletion in excess of cost depletion related to U.S. operations. The 2018 estimated annual effective tax rate before discrete items at March 31, 2018 was 0.1%. The rate in the comparable prior-year period was significantly lower due to the reversal of valuation allowance in the same period.

For the three months endedMarch 31, 2019 and 2018, we recorded discrete items that resulted in an income tax benefit of $0.4 million and expense of $15.7 million, respectively. The prior-year period expense of $15.7 million primarily relates to the $14.5 million reduction of the refundable AMT credit recorded in Income tax receivable, non-current in our Statements of Unaudited Condensed Consolidated Financial Position based on the sequestration guidance issued by the Internal Revenue Service during the first quarter of 2018. This position was subsequently reversed by the Internal Revenue Service during the fourth quarter of 2018. The prior-year period expense was a $15.7 million reduction of an asset and did not result in a cash tax outlay.

Mine Closure

The accrued closure obligation for our active mining operations provides for contractual and legal obligations associated with the eventual closure of the mining operations. The closure date for each of our active operating mine sites was determined based on the exhaustion date of the remaining iron ore reserves. The closure date and expected timing of the capital requirements to meet our obligations for our indefinitely idled or closed mines is determined based on the unique circumstances of each property. For indefinitely idled or closed mines, the accretion of the liability is recognized over the anticipated timing of remediation. The amortization of the related asset and accretion of the liability is recognized over the estimated mine lives for our active operations.

Derivatives Not Designated as Hedging Instruments

Customer Supply Agreement

A supply agreement with one customer provides for supplemental revenue or refunds to the customer based on the average annual daily steel market price for hot-rolled coil steel at the time the iron ore product is consumed in the customer’s blast furnace. The supplemental pricing is characterized as a freestanding derivative and is required to be accounted for separately once control transfers to the customer. The derivative instrument, which is finalized based on a future price, is adjusted to fair value through Product revenues each reporting period based upon current market data and forward-looking estimates provided by management until the pellets are consumed and the amounts are settled.

Provisional Pricing Arrangements

Certain of our supply agreements specify provisional price calculations, where the pricing mechanisms generally are based on market pricing, with the final revenue rate based on certain market inputs at a specified period in time in the future, per the terms of the supply agreements. Market inputs are tied to indexed price adjustment factors that are integral to the iron ore supply contracts and vary based on the agreement. The pricing mechanisms typically include adjustments based upon changes in the Platts 62% Price, Atlantic Basin pellet premiums, Platts international indexed freight rates and changes in specified Producer Price Indices, including those for industrial commodities, fuel and steel. The pricing adjustments generally operate in the same manner, with each factor typically comprising a portion of the price adjustment, although the weighting of each factor varies based upon the specific terms of each agreement. The price adjustment factors have been evaluated to determine if they qualify as embedded derivatives. The price adjustment factors share the same economic characteristics and risks as the host contract and are integral to the host contract as inflation adjustments; accordingly, they have not been separately valued as derivative instruments.

Revenue is recognized generally upon delivery to our customers. Revenue is measured at the point that control transfers and represents the amount of consideration we expect to receive in exchange for transferring goods. Changes in the expected revenue rate from the date that control transfers through final settlement of contract terms is recorded in accordance with ASC Topic 815 and is characterized as a derivative and accounted for separately.  Subsequently, the derivative instruments are adjusted to fair value through Product revenues each reporting period based upon current market data and forward-looking estimates provided by management until the final revenue rate is determined.

The provisional amounts represent the difference between the amount we expect to receive when revenue was initially measured at the point control transfers and our subsequent estimate of the final revenue rate based on the price calculation established in the supply agreements.

Asia Pacific Iron Ore Operations

Background

In January 2018, we announced that we would accelerate the time frame for the planned closure of our Asia Pacific Iron Ore mining operations in Australia. In April 2018, we committed to a course of action leading to the permanent closure of the Asia Pacific Iron Ore mining operations and, as planned, completed our final shipment in June 2018. Factors considered in this decision included increasingly discounted prices for lower-iron-content ore and the quality of the remaining iron ore reserves.

During 2018, we sold all of the assets of our Asia Pacific Iron Ore business through a series of sales to third parties.As a result of our planned exit, management determined that our Asia Pacific Iron Ore operating segment met the criteria to be classified as held for sale and a discontinued operation under ASC Topic 205, Presentation of Financial Statements. As such, all Asia Pacific Iron Ore operating segment results are classified within discontinued operations.

COMMITMENTS AND CONTINGENCIES

NOTE 20 - COMMITMENTS AND CONTINGENCIES

Purchase Commitments

In 2017, we began to incur capital commitments related to the construction of our HBI production plant in Toledo, Ohio. In total, we expect to spend approximately $830 million on the HBI production plant, exclusive of construction-related contingencies and capitalized interest through 2020. Through March 31, 2019, we have entered into contracts and purchase orders for approximately $780 million of the total capital investment for the HBI production plant, of which a total of approximately $265 million has been expended project-to-date, including deposits. We expect expenditures of approximately $290 million during the remaining nine months of 2019. Of the remaining committed capital, expenditures of approximately $275 million are expected to be made during 2020.

Contingencies

We are currently the subject of, or party to, various claims and legal proceedings incidental to our operations. If management believes that a loss arising from these matters is probable and can reasonably be estimated, we record the amount of the loss or the minimum estimated liability when the loss is estimated using a range, and no point within the range is more probable than another. As additional information becomes available, any potential liability related to these matters is assessed and the estimates are revised, if necessary. Based on currently available information, management believes that the ultimate outcome of these matters, individually and in the aggregate, will not have a material effect on our financial position, results of operations or cash flows. However, these claims and legal proceedings are subject to inherent uncertainties and unfavorable rulings could occur. An unfavorable ruling could include monetary damages, additional funding requirements or an injunction. If an unfavorable ruling were to occur, there exists the possibility of a material impact on the financial position and results of operations for the period in which the ruling occurs or future periods. However, we do not believe that any pending claims or legal proceedings will result in a material liability in relation to our consolidated financial statements.

When combined with the additional amount of share repurchase authorization, the Company now has authorization to repurchase common shares up to a maximum of approximately $129 million as of April 25, 2019. Such share repurchases may be made via acquisitions in the open market or privately negotiated transactions, including through accelerated share repurchases or pursuant to the terms of a Rule 10b5-1 plan.

Supplemental Guarantor Information [Text Block]

NOTE 22 - SUPPLEMENTARY GUARANTOR INFORMATION

The accompanying unaudited condensed consolidating financial information has been prepared and presented pursuant to SEC Regulation S-X, Rule 3-10, “Financial Statements of Guarantors and Issuers of Guaranteed Securities Registered or Being Registered.” Certain of our subsidiaries (the "Guarantors") have guaranteed the obligations under the $1.075 billion5.75% 2025 Senior Notes issued by Cleveland-Cliffs Inc. See NOTE 7 - DEBT AND CREDIT FACILITIES for further information.

The following presents the unaudited condensed consolidating financial information for: (i) the Parent Company and the Issuer of the guaranteed obligations (Cleveland-Cliffs Inc.); (ii) the Guarantor subsidiaries, on a combined basis; (iii) the non-guarantor subsidiaries, on a combined basis; (iv) consolidating eliminations; and (v) Cleveland-Cliffs Inc. and subsidiaries on a consolidated basis. Each Guarantor subsidiary is 100% owned by the Parent Company as of March 31, 2019 and December 31, 2018. The unaudited condensed consolidating financial information is presented as if the Guarantor structure at March 31, 2019 existed for all periods presented.

Each of the Guarantor subsidiaries fully and unconditionally guarantee, on a joint and several basis, the obligations of Cleveland-Cliffs Inc. under the $1.075 billion5.75% 2025 Senior Notes. The guarantee of a Guarantor subsidiary will be automatically and unconditionally released and discharged, and such Guarantor subsidiary’s obligations under the guarantee and the related indenture governing the $1.075 billion5.75% 2025 Senior Notes (the “Indenture”) will be automatically and unconditionally released and discharged, upon:

(a) any sale, exchange, transfer or disposition of such Guarantor subsidiary (by merger, consolidation, or the sale of) or the capital stock of such Guarantor subsidiary after which the applicable Guarantor subsidiary is no longer a subsidiary of the Company or the sale of all or substantially all of such Guarantor subsidiary’s assets (other than by lease);

(b) upon designation of any Guarantor subsidiary as an “excluded subsidiary” (as defined in the Indenture); or

(c) upon defeasance or satisfaction and discharge of the Indenture.

Each entity in the unaudited consolidating financial information follows the same accounting policies as described in the consolidated financial statements. The accompanying unaudited condensed consolidating financial information has been presented on the equity method of accounting for all periods presented. Under this method, investments in subsidiaries are recorded at cost and adjusted for the subsidiaries’ cumulative results of operations, capital contributions and distributions, and other changes in equity. Elimination entries include consolidating and eliminating entries for investments in subsidiaries, and intra-entity activity and balances.
