NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

1. Accounting Policies and Basis of Presentation:

Compass Minerals International, Inc. (“CMI”), through its subsidiaries (collectively, the “Company”), is a leading producer of essential minerals that solve nature’s challenges, including salt for winter roadway safety and other consumer, industrial and agricultural uses, specialty plant nutrition minerals that improve the quality and yield of crops, and specialty chemicals for water treatment and other industrial processes. The Company’s principal products are salt, consisting of sodium chloride and magnesium chloride; plant nutrients, consisting of sulfate of potash (“SOP”), secondary nutrients and micronutrients; and specialty chemicals. The Company also provides records management services to businesses located in the United Kingdom (the “U.K.”). The Company’s production sites are located in the United States (“U.S.”), Canada, Brazil and the U.K. Except where otherwise noted, references to North America include only the continental U.S. and Canada, and references to the U.K. include only England, Scotland and Wales. References to “Compass Minerals,” “our,” “us” and “we” refer to CMI and its consolidated subsidiaries.

CMI is a holding company with no significant operations other than those of its wholly-owned subsidiaries. The consolidated financial statements include the accounts of CMI and its wholly-owned subsidiaries. All significant intercompany balances and transactions have been eliminated in consolidation.

The Company uses the equity method of accounting for equity securities when it has significant influence or when it has more than a minor ownership interest or more than minor influence over an investee’s operations but does not have a controlling financial interest. Initial investments are recorded at cost (including certain transaction costs) and are adjusted by the Company’s share of the investees’ undistributed earnings and losses.

The accompanying unaudited consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”) for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by U.S. GAAP for complete financial statements. These unaudited consolidated financial statements should be read in conjunction with the consolidated financial statements of the Company for the year ended December 31, 2019, as filed with the Securities and Exchange Commission (“SEC”) in its Annual Report on Form 10-K. In the opinion of management, all adjustments, consisting of normal recurring adjustments considered necessary for a fair presentation, have been included.

The Company experiences a substantial amount of seasonality in its sales with respect to its deicing salt products. As a result, sales and operating earnings are generally higher in the first and fourth quarters and lower during the second and third quarters of each year. In particular, sales of highway and consumer deicing salt and magnesium chloride products vary based on the severity of the winter conditions in areas where the products are used. Following industry practice in North America and the U.K., the Company seeks to stockpile sufficient quantities of deicing salt throughout the second, third and fourth quarters to meet the estimated requirements for the upcoming winter season. Production of deicing salt can also vary based on the severity or mildness of the preceding winter season. Due to the seasonal nature of the deicing product lines, operating results for the interim periods are not necessarily indicative of the results that may be expected for the full year.

The Company’s plant nutrition business is also seasonal. For example, the strongest demand for the Company’s plant nutrition products in Brazil typically occurs during the spring planting season. As a result, the Company and its customers generally build inventories during the low demand periods of the year to ensure timely product availability during the peak sales season. The seasonality of this demand results in the Company’s sales volumes and operating income for the Plant Nutrition South America segment usually being the highest during the third and fourth quarters of each year (as the spring planting season begins in September in Brazil).

Significant Accounting Policies

The Company’s significant accounting policies are detailed in “Note 2 – Summary of Significant Accounting Policies” within Item 8 of the Company’s Annual Report on Form 10-K for the year ended December 31, 2019.

Recent Accounting Pronouncements

In January 2017, the Financial Accounting Standards Board (“FASB”) issued guidance to simplify the accounting for goodwill impairment. The guidance removes Step 2 of the goodwill impairment test, which requires a hypothetical purchase price

7

allocation. A goodwill impairment will now be the amount by which a reporting unit’s carrying value exceeds its fair value, not to exceed the carrying amount of goodwill. All other goodwill impairment guidance remains largely unchanged. The adoption of this guidance on January 1, 2020 did not have an impact on the Company’s consolidated financial statements.

On January 1, 2020, the Company adopted guidance issued by the FASB related to credit losses for financial instruments, which replaces the incurred loss methodology with a current expected credit loss methodology (“CECL”). The Company has determined that its trade receivables are the only financial instrument that is within scope of this CECL guidance. The CECL methodology requires financial assets to be recorded at the net amount expected to be collected over the lifetime of the asset such that the estimated losses are accrued on the day the asset is acquired. The CECL methodology also requires financial assets to be aggregated and evaluated within pools with similar risk characteristics.

The Company has recorded an allowance on its trade receivables based on historical loss rates modified to consider supportable forecasts related to customer-specific and macroeconomic factors. For instance, the Company’s 2020 allowance for doubtful accounts considered the potential impact that the coronavirus pandemic could have on the collectability of its outstanding receivables. The Company’s customer pools are comprised of North American highway deicing customers, North American consumer and industrial customers, Plant Nutrition North America customers, Plant Nutrition South America customers and customers whose outstanding receivable balances have been sent to collections. Customers grouped within these pools have similar risk characteristics. The Company’s allowance for doubtful accounts consists of estimates of expected credit losses and accruals for returns and allowances. At the transition date of January 1, 2020, the implementation of CECL had an immaterial impact of less than $0.1 million on the Company’s consolidated financial statements. Under CECL, the Company had an allowance for doubtful accounts of $9.4 million and $8.2 million as of January 1, 2020, and June 30, 2020, respectively.

2. Revenue Recognition:

Nature of Products and Services

The Company’s Salt segment products include salt and magnesium chloride for use in road deicing and dust control, food processing, water softeners, and agricultural and industrial applications. The Company’s plant nutrition products include SOP, secondary nutrients, micronutrients and chemicals for the industrial chemical industry. In the U.K., the Company operates a records management business utilizing excavated areas of the Winsford salt mine with one other location in London, England.

Identifying the Contract

The Company accounts for a customer contract when there is approval and commitment from both parties, the rights of the parties and payment terms are identified, the contract has commercial substance and collectability of consideration is probable.

Identifying the Performance Obligations

At contract inception, the Company assesses the goods and services it has promised to its customers and identifies a performance obligation for each promise to transfer to the customer a distinct good or service (or bundle of goods or services). Determining whether products and services are considered distinct performance obligations that should be accounted for separately or aggregated together may require significant judgment.

Identifying and Allocating the Transaction Price

The Company’s revenues are measured based on consideration specified in the customer contract, net of any sales incentives and amounts collected on behalf of third parties such as sales taxes. In certain cases, the Company’s customer contracts may include promises to transfer multiple products and services to a customer. For multiple-element arrangements, the Company generally allocates the transaction price to each performance obligation in proportion to its stand-alone selling price.

When Performance Obligations Are Satisfied

The vast majority of the Company’s revenues are recognized at a point in time when the performance obligations are satisfied based upon transfer of control of the product or service to a customer. To determine when the control of goods is transferred, the Company typically assesses, among other things, the shipping terms of the contract, as shipping is an indicator of transfer of control. Some of the Company’s products are sold when the control of the goods transfers to the customer at the time of shipment. There are also instances when the Company provides shipping services to deliver its products. Shipping and handling costs that occur before the customer obtains control of the goods are deemed to be fulfillment activities and are accounted for as fulfillment costs. The Company recognizes shipping and handling costs that are incurred after the customer obtains control of the goods as fulfillment costs which are accrued at the time of revenue recognition.

8

Significant Payment Terms

The customer contract states the final terms of the sale, including the description, quantity and price of each product or service purchased. Payment is typically due in full within 30 days of delivery. The Company does not adjust the consideration for the effects of a significant financing component if the Company expects, at contract inception, that the period between when the good or service is transferred to the customer and when the customer pays for that good or service will be one year or less.

Refunds, Returns and Warranties

The Company’s products are generally not sold with a right of return and the Company does not generally provide credits or incentives, which may be required to be accounted for as variable consideration when estimating the amount of revenue to be recognized. The Company uses historical experience to estimate accruals for refunds due to manufacturing or other defects.

See Note 10 for disaggregation of revenue by segment, type and geographical region.

3.  Leases:

In February 2016, the FASB issued guidance which requires lessees to recognize on their balance sheet a right-of-use asset which represents a lessee’s right to use the underlying asset and a lease liability which represents a lessee’s obligation to make lease payments for the right to use the asset. In addition, the guidance requires expanded qualitative and quantitative disclosures. The Company adopted this guidance beginning in the first quarter of 2019, using a modified retrospective transition method, which required the cumulative effect of this change in accounting of $0.1 million to be recorded as an adjustment to beginning retained earnings. The Company elected the package of transition provisions available for existing contracts, which allowed entities to carryforward the historical assessment of whether the contract contained a lease and the lease classification.

The Company enters into leases for warehouses and depots, rail cars, vehicles, mobile equipment, office space and certain other types of property and equipment. The Company determines whether an arrangement is or contains a lease at the inception of the contract. The right-of-use asset and lease liability are recognized based on the present value of the future minimum lease payments over the estimated lease term. Lease expense for minimum lease payments is recognized on a straight-line basis over the lease term. The Company estimates its incremental borrowing rate for each lease based upon the estimated lease term, the type of asset and the location of the leased asset. The most significant judgments in the application of the FASB guidance include whether a contract contains a lease and the lease term.

Leases with an initial term of 12 months or less are not recorded on the Company’s Consolidated Balance Sheets. The Company recognizes lease expense for these short-term leases on a straight-line basis over the lease term. Many of the Company’s leases include one or more options to renew and extend the initial lease term. The exercise of lease renewal options is generally at the Company’s discretion. The lease term includes renewal periods in only those instances in which the Company determines it is reasonably assured of renewal.

The depreciable life of assets and leasehold improvements are limited by the expected lease term, unless there is a transfer of title or purchase option reasonably certain of exercise. In these instances, the assets are depreciated over the useful life of the asset.

The Company has elected the practical expedient available under the FASB guidance to not separate lease and nonlease components on all of its lease categories. As a result, many of the Company’s leases include variable payments for services (such as handling or storage) or payments based on the usage of the asset. In addition, certain of the Company’s lease agreements include rental payments that are adjusted periodically for inflation. The Company’s lease agreements do not contain any material residual value guarantees or any material restrictive covenants. The Company’s sublease income is immaterial.

The change in goodwill between December 31, 2019 and June 30, 2020 was due to the impact from translating foreign-denominated amounts to U.S. dollars.

7. Income Taxes:

The Company’s effective income tax rate differs from the U.S. statutory federal income tax rate primarily due to U.S. statutory depletion, state income taxes (net of federal tax benefit), foreign income, mining and withholding taxes, global intangible low-taxed income and interest expense recognition differences for book and tax purposes.

The Company had $11.4 million and $18.8 million as of June 30, 2020 and December 31, 2019, respectively, of gross foreign federal net operating loss (“NOL”) carryforwards that have no expiration date, $1.3 million and $1.7 million, respectively, of gross foreign federal NOL carryforwards which expire beginning in 2033 and $0.2 million and $0.3 million, respectively, of net operating tax-effected state NOL carryforwards which expire beginning in 2027.

Canadian provincial tax authorities have challenged tax positions claimed by one of the Company’s Canadian subsidiaries and have issued tax reassessments for years 2002-2015. The reassessments are a result of ongoing audits and total $127.4 million, including interest, through June 30, 2020. The Company disputes these reassessments and will continue to work with the appropriate authorities in Canada to resolve the dispute. There is a reasonable possibility that the ultimate resolution of this dispute, and any related disputes for other open tax years, may be materially higher or lower than the amounts the Company has reserved for such disputes. In connection with this dispute, local regulations require the Company to post security with the tax authority until the dispute is resolved. The Company has posted collateral in the form of a $93.7 million performance bond and has paid $36.3 million to the Canadian tax authorities (most of which is recorded in other assets in the Consolidated Balance Sheets).

The Company expects that it will be required by local regulations to provide security for additional interest on the above unresolved disputed amounts and for any future reassessments issued by these Canadian tax authorities in the form of cash, letters of credit, performance bonds, asset liens or other arrangements agreeable with the tax authorities until the disputes are resolved.

The Company expects that the ultimate outcome of these matters will not have a material impact on its results of operations or financial condition. However, the Company can provide no assurance as to the ultimate outcome of these matters, and the impact could be material if they are not resolved in the Company’s favor. As of June 30, 2020, the Company believes it has adequately reserved for these reassessments.

Additionally, the Company has other uncertain tax positions as well as assessments and disputed positions with taxing authorities in its various jurisdictions, which are consistent with those matters disclosed in the Company’s Annual Report on Form 10-K for the year ended December 31, 2019.

Settlements

In the fourth quarter of 2017, the Company, the Canadian Revenue Authority (“CRA”) and the U.S. Internal Revenue Service (“IRS”) reached a settlement agreement on transfer pricing issues for the Company’s 2007-2012 tax years. As a result of this settlement agreement, the Company recognized $13.8 million of tax expense in its 2017 Consolidated Statements of Operations related to the Company’s Canadian tax positions for the years 2007-2016. The recording of this settlement resulted in increased sales for the Company’s Canadian subsidiary of $85.7 million and increased offsetting expenses for the Company’s U.S. subsidiary in 2017 causing a domestic loss and significant foreign income. During 2018, in accordance with the settlement agreement, the Company’s U.S. subsidiary made intercompany cash payments of $85.7 million to its Canadian subsidiary and tax payments to Canadian taxing authorities of $17.5 million. The remaining liability was satisfied in 2019 with tax payments of $5.3 million. Corresponding tax refunds of $21.4 million were received primarily in 2019 from U.S. taxing authorities, with the remaining refund of approximately $1.6 million expected in 2020 (recorded in other current assets in the Consolidated Balance Sheets).

In the fourth quarter of 2018, the Company, the CRA and the IRS reached a settlement agreement on transfer pricing and management fees as part of an advanced pricing agreement that covers tax years 2013-2021. The tax expense was previously recognized in 2017, however the recording of this settlement resulted in increased sales for the Company’s Canadian subsidiary of $106.1 million and offsetting expenses for the Company’s U.S. subsidiary in 2018 causing a domestic loss and significant foreign income. During 2019, in accordance with the settlement agreement, the Company’s U.S. subsidiary made intercompany cash payments of $106.1 million to its Canadian subsidiary and tax payments to Canadian taxing authorities of $29.9 million, with the remaining $1.4 million of tax payments to be paid during 2020. Corresponding tax refunds of $59.7 million have been received as of June 30, 2020 from U.S. taxing authorities, of which $55.0 million was received during the first quarter of 2020, with the remaining $1.9 million expected in 2020 (recorded in other current assets in its Consolidated Balance Sheets).

Long-term debt	$	1,247.5	$	1,363.9

In the first quarter of 2020, the Company entered into three loans totaling $20.0 million which mature between February 2021 and March 2022, respectively. Two of the loans were denominated in Brazilian reais and one loan was denominated in euros. In connection with the loan denominated in euros, the Company entered into a swap to exchange principal and interest payments

13

denominated in euros to Brazilian reais (see Note 12). These loans bear interest ranging from 143% - 150% of CDI. As of June 30, 2020, the weighted average interest rate of all the Company’s outstanding debt was approximated 5.49%.

During the first quarter of 2020, the Company sold approximately $3.4 million of Brazilian receivables for $3.3 million. The proceeds of the transaction were used to maintain liquidity for working capital needs. The Company is contingently liable for up to 20% of the sale balance up to $0.7 million if the banks are unable to collect on these accounts. See Note 15 for discussion of the Company’s securitization of a portion of its U.S. trade receivables.

As of June 30, 2020, the term loans and revolving credit facility under the Company’s credit agreement were secured by substantially all existing and future U.S. assets, the Goderich mine in Ontario, Canada and capital stock of certain subsidiaries.

9. Commitments and Contingencies:

The Wisconsin Department of Agriculture, Trade and Consumer Protection (“DATCP”) and the Wisconsin Department of Natural Resources (“DNR”) have information indicating that agricultural chemicals are present within the subsurface area of the Company’s property located in Kenosha, Wisconsin. The agricultural chemicals were used by previous owners and operators of the site. None of the identified chemicals have been used in association with the Company’s operations since it acquired the property in 2002. DATCP and DNR have directed the Company to conduct further investigations into the environmental conditions at the Kenosha property. The Company continues on-property investigations and has provided the findings to DATCP and DNR as they have become available. All investigations and mitigation activities to date, and any potential future remediation work, are being conducted under the Wisconsin Agricultural Chemical Cleanup Program, which provides for reimbursement of some of the costs.

The Company conducts business operations in several countries and is subject to various federal and local labor, social security, environmental and tax laws. While the Company believes it complies with such laws, they are complex and subject to interpretation. In addition to the tax assessments discussed in Note 7, the Company’s Brazilian subsidiaries are party to administrative tax proceedings and claims which totaled $7.5 million and $15.8 million as of June 30, 2020 and December 31, 2019, respectively, and relate primarily to value added tax, state tax (ICMS) and social security tax (PIS and COFINS) assessments. The Company has assessed the likelihood of a loss at less than probable and therefore, has not established a reserve for these matters. The Company also assumed liabilities for labor-related matters in connection with the 2016 acquisition of Compass Minerals South America, which are primarily related to compensation, labor benefits and consequential tax claims that totaled $4.2 million and $5.6 million as of June 30, 2020 and December 31, 2019, respectively. The Company believes the maximum exposure for these other labor matters totaled approximately $18 million and $25 million as of June 30, 2020 and December 31, 2019, respectively.

The Division of Enforcement of the SEC is investigating the Company’s disclosures concerning the operation of the Goderich mine. The Company has cooperated with this investigation and will continue to do so. While it is not possible to predict the timing or the outcome of the SEC inquiry, the Company believes that this matter will not have a material impact on its results of operation, cash flows or financial position.

The Company is also involved in legal and administrative proceedings and claims of various types from the ordinary course of the Company’s business.

Management cannot predict the outcome of legal claims and proceedings with certainty. Nevertheless, management believes the outcome of legal proceedings and claims, which are pending or known to be threatened, even if determined adversely, will not, individually or in the aggregate, have a material adverse effect on the Company’s results of operations, cash flows or financial position.

10. Operating Segments:

The Company’s reportable segments are strategic business units that offer different products and services, and each business requires different technology and marketing strategies. The Company has three reportable segments: Salt, Plant Nutrition North America and Plant Nutrition South America. The Salt segment produces and markets salt, consisting of sodium chloride and magnesium chloride, for use in road deicing for winter roadway safety and for dust control, food processing, water softeners and other consumer, agricultural and industrial applications. Plant nutrients, including SOP, secondary nutrients and micronutrients are produced and marketed through the Plant Nutrition North America segment. The Plant Nutrition South America segment operates two primary businesses in Brazil – agricultural productivity and chemical solutions. The agricultural productivity division manufactures and distributes a broad offering of specialty plant nutrition solution-based products that are used in direct soil and foliar applications, as well as through irrigation systems and for seed treatment. The chemical solutions division manufactures and markets specialty chemicals for the industrial chemical industry.

11. Stockholders’ Equity and Equity Instruments:

In May 2020, the Company’s stockholders approved the 2020 Incentive Award Plan (the “2020 Plan”), which authorizes the issuance of 2,977,933 shares of Company common stock. Since the date the 2020 Plan was approved, the Company ceased issuing equity awards under the 2015 Incentive Award Plan (as amended, the “2015 Plan”). Since the approval of the 2015 Plan in May 2015, the Company ceased issuing equity awards under the 2005 Incentive Award Plan (as amended, the “2005 Plan”). The 2005 Plan, 2015 Plan and 2020 Plan allow for grants of equity awards to executive officers, other employees and directors, including restricted stock units (“RSUs”), performance stock units (“PSUs”), stock options and deferred stock units. The grants occur following approval by the compensation committee of the Company’s board of directors, with the amount and terms communicated to employees shortly thereafter.

Options

Most of the stock options granted under the 2005 Plan and 2015 Plan vest ratably, in tranches, over a four-year service period. Unexercised options expire after seven years. Options do not have dividend or voting rights. Upon vesting, each option can be exercised to purchase one share of the Company’s common stock. The exercise price of options is equal to the closing stock price on the grant date.

17

To estimate the fair value of options on the grant date, the Company uses the Black-Scholes option valuation model. Award recipients are grouped according to expected exercise behavior. Unless better information is available to estimate the expected term of the options, the estimate is based on historical exercise experience. The risk-free rate, using U.S. Treasury yield curves in effect at the time of grant, is selected based on the expected term of each group. The Company’s historical stock price is used to estimate expected volatility. The fair value and inputs used to calculate fair value for options granted in the first six months of 2020 are included in the table below:

Fair value of options granted	$10.91
Exercise price	$58.91
Expected term (years)	4.75
Expected volatility	29.3%
Dividend yield	3.5%
Risk-free rate of return	1.6%

RSUs

Typically, the RSUs granted under the 2015 Plan and 2020 Plan vest after three years and one year of service, respectively. RSUs entitle the holders to one share of common stock for each vested RSU. Unvested RSUs do not have voting rights but are entitled to receive non-forfeitable dividends (generally after a performance hurdle has been satisfied for the year of the grant) or other distributions equal to those declared on the Company’s common stock for RSUs that are earned as a result of the satisfaction of the performance hurdle. The closing stock price on the grant date is used to determine the fair value of RSUs.

PSUs

The PSUs granted under the 2015 Plan are either total shareholder return PSUs (“TSR PSUs”) or return on invested capital PSUs (“ROIC PSUs”). The actual number of shares of the Company’s common stock that may be earned with respect to TSR PSUs is calculated by comparing the Company’s total shareholder return to the total shareholder return for each company comprising the Company’s peer group (for TSR PSUs granted in 2018 and later) over the three-year performance period and may range from 0% to 200% of the target number of shares based upon the attainment of these market conditions. The actual number of shares of common stock that may be earned with respect to ROIC PSUs is calculated based on the average of the Company’s annual return on invested capital for each year in the three-year performance period and may range from 0% to 200% of the target number of shares based upon the attainment of these performance conditions.

PSUs represent a target number of shares of the Company’s common stock that may be earned before adjustment based upon the attainment of certain conditions. Holders of PSUs do not have voting rights but are entitled to receive non-forfeitable dividends or other distributions equal to those declared on the Company’s common stock for PSUs that are earned, which are paid when the shares underlying the PSUs are paid.

To estimate the fair value of the TSR PSUs on the grant date, the Company uses a Monte-Carlo simulation model, which simulates future stock prices of the Company as well as the companies comprising the Russell 3000 Index or the Company’s peer group depending on the year granted. This model uses historical stock prices to estimate expected volatility and the Company’s correlation to the Russell 3000 Index or peer group. The risk-free rate was determined using the same methodology as the option valuations as discussed above. The Company’s closing stock price on the grant date was used to estimate the fair value of the ROIC PSUs. The Company will adjust the expense of the ROIC PSUs based upon its estimate of the number of shares that will ultimately vest at each interim date during the vesting period.

During the six months ended June 30, 2020, the Company reissued the following number of shares from treasury stock: no shares related to the exercise of stock options, 28,835 shares related to the release of RSUs which vested, 11,575 shares related to the release of PSUs which vested and 9,756 shares related to stock payments. In 2019, the Company issued 32,197 shares from treasury stock. The Company withheld 14,627 shares with a fair value of $0.7 million related to the vesting of RSUs and PSUs during the first six months of 2020. The fair value of the shares were valued at the closing price at the vesting date and represent the employee tax withholding for the employee’s compensation. The Company recognized a tax deficiency of $0.1 million from its equity compensation awards as an increase to income tax expense during the first six months of 2020. During the first six months of 2020 and 2019, the Company recorded $5.6 million (includes $0.5 million paid in cash) and $3.4 million, respectively, of compensation expense pursuant to its stock-based compensation plans. No amounts have been capitalized. The following table summarizes stock-based compensation activity during the six months ended June 30, 2020:

12. Derivative Financial Instruments:

The Company is subject to various types of market risks, including interest rate risk, foreign currency exchange rate transaction and translation risk and commodity pricing risk. Management may take actions to mitigate the exposure to these types of risks, including entering into forward purchase contracts and other financial instruments. Currently, the Company manages a portion of its commodity pricing and foreign currency exchange rate risks by using derivative instruments. From time to time, the Company may enter into immaterial foreign exchange contracts to mitigate foreign exchange risk on its sales and accounts receivable. The Company does not seek to engage in trading activities or take speculative positions with any financial instrument arrangement. The Company has entered into natural gas derivative instruments and foreign currency derivative instruments with counterparties it views as creditworthy. However, the Company does attempt to mitigate its counterparty credit risk exposures by, among other things, entering into master netting agreements with some of these counterparties. The Company records derivative financial instruments as either assets or liabilities at fair value in the Consolidated Balance Sheets.

Derivatives qualify for treatment as hedges when there is a high correlation between the change in fair value of the derivative instrument and the related change in value of the underlying hedged item. Depending on the exposure being hedged, the Company must designate the hedging instrument as a fair value hedge, a cash flow hedge or a net investment in foreign operations hedge. For the qualifying derivative instruments that have been designated as hedges, the change in fair value is recognized through earnings when the underlying transaction being hedged affects earnings, allowing a derivative’s gains and losses to offset related results from the hedged item in the statements of operations. Any ineffectiveness related to these hedges was not material for any of the periods presented. For derivative instruments that have not been designated as hedges, the entire change in fair value is recorded through earnings in the period of change.

Natural Gas Derivative Instruments

Natural gas is consumed at several of the Company’s production facilities, and changes in natural gas prices impact the Company’s operating margin. The Company’s objective is to reduce the earnings and cash flow impacts of changes in market prices of natural gas by fixing the purchase price of up to 90% of its forecasted natural gas usage. It is the Company’s policy to consider hedging portions of its natural gas usage up to 36 months in advance of the forecasted purchase. As of June 30, 2020, the Company had entered into natural gas derivative instruments to hedge a portion of its natural gas purchase requirements through December 2021. As of June 30, 2020 and December 31, 2019, the Company had agreements in place to hedge forecasted natural gas purchases of 3.1 million and 2.8 million MMBtus, respectively. All natural gas derivative instruments held by the Company as of June 30, 2020 and December 31, 2019 qualified and were designated as cash flow hedges. As of June 30, 2020, the Company expects to reclassify from accumulated other comprehensive loss to earnings during the next twelve months $0.2 million of net losses on derivative instruments related to its natural gas hedges.

Foreign Currency Derivatives Not Designated as Hedges

In March 2020, the Company entered into forward instruments to swap currency denominated in U.S. dollars to Canadian dollars for a future intercompany payment from a U.S. subsidiary to a Canadian subsidiary. These instruments matured in April 2020 with combined notional amounts of $89.9 million. The objective of the instruments was to mitigate the foreign currency fluctuation risk related to intercompany payments denominated in a currency other than U.S. dollars, the Company’s functional currency. The instrument was not designated as a hedge. During the six months ended June 30, 2020, the Company recognized a foreign exchange loss of $3.1 million in its Consolidated Statements of Operations for these agreements.

Foreign Currency Derivatives Designated as Hedges

The Company has entered into U.S. dollar-denominated debt instruments to provide funds for its operations in Brazil. The Company may also concurrently enter into foreign currency agreements whereby the Company agrees to swap interest and principal payments on loans denominated in U.S. dollars for principal and interest payments denominated in Brazilian reais, its Brazil subsidiary’s functional currency. The objective of the swap agreements is to mitigate the foreign currency fluctuation risk related to holding debt denominated in a currency other than the Company’s Brazil subsidiary’s functional currency. As of June 30, 2020, the Company had a swap agreement in place to hedge $9.5 million of a loan denominated in a currency other than its Brazil subsidiary’s functional currency. Payments on this loan are due on various dates extending through February 2021. As of June 30, 2020, this foreign currency derivative instrument qualified and was designated as a cash flow hedge. As of June 30, 2020, the Company expects to reclassify from accumulated other comprehensive loss to earnings during the next twelve months $2.2 million of net gains on derivative instruments related to this foreign currency swap agreement.

21

The following tables present the fair value of the Company’s hedged items as of June 30, 2020 and December 31, 2019 (in millions):

	Asset Derivatives			Liability Derivatives
Derivatives designated as hedging instruments:	Consolidated Balance Sheets Location	June 30, 2020		Consolidated Balance Sheets Location	June 30, 2020
Commodity contracts	Other current assets	$	0.5	Accrued expenses and other current liabilities	$	0.7
Commodity contracts	Other assets	0.1		Other noncurrent liabilities	0.1
Swap contracts	Other current assets	2.2		Accrued expenses and other current liabilities	—
Total derivatives designated as hedging instruments(a)(b)		$	2.8		$	0.8

(a)The Company has master netting agreements with both of its commodity hedge counterparties and accordingly has netted in its Consolidated Balance Sheets $0.6 million of its commodity contracts that are in a receivable position against its contracts in payable positions.

(b)The Company has commodity hedge agreements with two counterparties and a foreign currency swap agreement with one counterparty. Amounts recorded as liabilities for the Company’s commodity contracts are payable to both counterparties and amounts recorded as assets for the Company’s foreign currency swap agreements are receivable from one counterparty. 

	Asset Derivatives			Liability Derivatives
Derivatives designated as hedging instruments:	Consolidated Balance Sheets Location	December 31, 2019		Consolidated Balance Sheets Location	December 31, 2019
Commodity contracts	Other current assets	$	0.3	Accrued expenses and other current liabilities	$	0.8
Commodity contracts	Other assets	0.1		Other noncurrent liabilities	0.2
Swap contracts	Other current assets	2.8		Accrued expenses and other current liabilities	—
Total derivatives designated as hedging instruments(a)(b)		$	3.2		$	1.0

(a)The Company has master netting agreements with its commodity hedge counterparties and accordingly has netted in its Consolidated Balance Sheets $0.4 million of its commodity contracts that are in a receivable position against its contracts in payable positions.

(b)The Company has both commodity hedge and foreign currency swap agreements with two counterparties each. Amounts recorded as liabilities for the Company’s commodity contracts are payable to both counterparties, and amounts recorded as assets for the Company’s foreign currency swap agreements are receivable from both counterparties. 

13. Fair Value Measurements:

The Company’s financial instruments are measured and reported at their estimated fair values. Fair value is the price that would be received upon the sale of an asset or paid to transfer a liability in an orderly transaction. When available, the Company uses quoted prices in active markets to determine the fair values for its financial instruments (Level 1 inputs) or, absent quoted market prices, observable market-corroborated inputs over the term of the financial instruments (Level 2 inputs). The Company does not have any unobservable inputs that are not corroborated by market inputs (Level 3 inputs).

The Company holds marketable securities associated with its defined contribution and pre-tax savings plans, which are valued based on readily available quoted market prices. The Company utilizes derivative instruments to manage its risk of changes in natural gas prices and its risk of changes in foreign currency exchange rates (see Note 12). The fair values of the natural gas and foreign currency derivative instruments are determined using market data of forward prices for all of the Company’s contracts. 

22

The estimated fair values for each type of instrument are presented below (in millions):

	June 30, 2020		Level One		Level Two		Level Three
Asset Class:
Mutual fund investments in a non-qualified savings plan(a)	$	1.6	$	1.6	$	—	$	—
Derivatives – foreign currency contracts, net	2.2		—		2.2		—
Total Assets	$	3.8	$	1.6	$	2.2	$	—

Derivatives – natural gas instruments, net	(0.6)		—		(0.6)		—
Total Liabilities	$	(2.0)	$	(1.4)	$	(0.6)	$	—

(a)Includes mutual fund investments of approximately 30% in the common stock of large-cap U.S. companies, 15% in the common stock of small to mid-cap U.S. companies, 5% in the common stock of international companies, 10% in bond funds, 20% in short-term investments and 20% in blended funds.

Cash and cash equivalents, receivables (net of allowance for doubtful accounts) and payables are carried at cost, which approximates fair value due to their liquid and short-term nature. The Company’s investments related to its nonqualified savings plan of $1.6 million and $1.4 million at June 30, 2020 and December 31, 2019, respectively, are stated at fair value based on quoted market prices. As of June 30, 2020 and December 31, 2019, the estimated amount a third party would pay for the Company’s fixed-rate 4.875% Senior Notes due July 2024, based on available trading information (Level 2), totaled $252.5 million and $249.1 million, respectively, compared with the aggregate principal amount at maturity of $250.0 million. As of June 30, 2020 and December 31, 2019, the estimated amount a third party would pay for the Company’s fixed-rate 6.75% Senior Notes due December 2027, based on available trading information (Level 2), totaled $530.0 million and $530.6 million, respectively, compared with the aggregate principal amount at maturity of $500.0 million. The estimated amount a third party would pay at June 30, 2020 and December 31, 2019 for the amounts outstanding under the Company’s term loans and revolving credit facility, based upon available bid information received from the Company’s lender (Level 2), totaled $448.9 million and $552.8 million, respectively, compared with the aggregate principal balance of $454.0 million and $560.0 million, respectively. The Brazilian loans have floating rates and their fair value approximates their carrying value.

14. Earnings per Share:

The Company calculates earnings per share using the two-class method. The two-class method requires allocating the Company’s net earnings to both common shares and participating securities. The following table sets forth the computation of basic and diluted earnings per common share (in millions, except for share and per-share data):

	Three Months Ended June 30,				Six Months Ended June 30,
	2020		2019		2020		2019
Numerator:
Net earnings (loss)	$	1.7	$	(11.8)	$	29.3	$	(4.2)
Less: net earnings allocated to participating securities(a)	(0.4)		(0.3)		(0.8)		(0.5)
Net earnings (loss) available to common shareholders	$	1.3	$	(12.1)	$	28.5	$	(4.7)
Denominator (in thousands):
Weighted-average common shares outstanding, shares for basic earnings per share	33,915		33,883		33,903		33,878
Weighted-average awards outstanding(b)	—		—		—		—
Shares for diluted earnings per share	33,915		33,883		33,903		33,878
Net earnings (loss) per common share, basic	$	0.04	$	(0.36)	$	0.85	$	(0.14)
Net earnings (loss) per common share, diluted	$	0.04	$	(0.36)	$	0.84	$	(0.14)

(a)Weighted participating securities include RSUs and PSUs that receive non-forfeitable dividends and consist of 411,000 and 412,000 weighted participating securities for the three and six months ended June 30, 2020, respectively, and 319,000 and 276,000 weighted participating securities for the three and six months ending June 30, 2019, respectively.

(b)For the calculation of diluted net earnings per share, the Company uses the more dilutive of either the treasury stock method or the two-class method to determine the weighted-average number of outstanding common shares. In addition, the Company had 1,255,000 and 1,265,000 weighted-average equity awards outstanding for the three and six months ended June 30, 2020, respectively, and 1,184,000 and 992,000 weighted-average equity awards outstanding for the three and six months ended June 30, 2019, respectively, that were anti-dilutive.

15. Securitization:

On June 30, 2020, certain of the Company’s U.S. subsidiaries entered into a three-year committed revolving accounts receivable financing facility (the “AR Facility”) of up to $100 million with PNC Bank, National Association (“PNC”), as administrative agent and lender, and PNC Capital Markets, LLC, as structuring agent.

In connection with the AR Facility, two of the Company’s U.S. subsidiaries will, from time to time sell and contribute accounts receivable and certain related assets to a special purposes entity and wholly-owned U.S. subsidiary of the Company (the “SPE”). The SPE will finance its acquisition of the receivables by obtaining secured loans from PNC and the other lenders party to a receivables financing agreement. A U.S. subsidiary of the Company will service the accounts receivables on behalf of the SPE for a fee. In addition, the Company has agreed to guarantee the performance by its subsidiaries. The Company and its subsidiaries do not guarantee the loan principal or interest under the receivables financing agreement or the collectability of the receivables under the AR Facility. In July 2020, the Company received proceeds from its first loan amount of $24.0 million.

The purchase price for the sale of receivables will consist of cash available to the SPE from loans under the AR Facility and from collections on previously sold receivables and, to the extent the SPE does not have funds available to pay the purchase price due on any day in cash, through an increase in the principal amount of a subordinated intercompany loan. The SPE will pay monthly interest and fees with respect to amounts advanced by the lenders under the AR Facility.

The SPE’s sole business consists of the purchase or acceptance through capital contributions of the receivables and the subsequent granting of a security interest in these receivables and related rights to PNC on behalf of the lenders under the AR Facility. The SPE is a separate legal entity with its own separate creditors who will be entitled, upon its liquidation, to be satisfied out of the SPE’s assets prior to any assets or value in the SPE becoming available to the Company and the assets of the SPE are not available to pay creditors of the Company or any of its affiliates other than the SPE.

COVID-19 Pandemic

The global spread of the COVID-19 pandemic in recent months has negatively impacted the global economy, disrupted global supply chains and created significant volatility and disruption of financial markets. As an essential business, we have continued

25

producing and delivering products that support critical industries such as transportation, agriculture, chemical, food, pharmaceutical and animal nutrition. However, we have instituted several measures in response to the COVID-19 pandemic.

•Employee welfare: Our management team has taken multiple actions to limit the exposure of employees to the spread of COVID-19, including instituting remote working where possible, adjusting shift schedules and crew sizes, restricting visitation to operational sites, curtailing all business-related commercial air travel, and increasing sanitation of offices and common areas within our facilities.

•Operations: Our manufacturing facilities in North America and Brazil remained in operation throughout the first quarter. Operations at our U.K. salt mine were idled near the end of March 2020 due to the very mild winter weather experienced in that market, along with U.K. government guidance on COVID-19 preventative measures. Mine operations resumed in mid-May 2020, utilizing a gradual ramp up.

•Supply chain and logistics: To date, we have experienced no material supply chain or logistics issues. We continue to evaluate potential supply chain and logistics impacts, proactively increase inventory levels of critical sourced inputs and identify secondary suppliers where possible. Both our operations and our logistics partners are deemed “essential” under current governmental guidance and we have worked to ensure we understand and comply with their safety precautions to limit potential disruptions.

The ultimate impact that COVID-19 will have on our 2020 results is unknown at this time. However, we have identified several potential impacts on our business, which include:

•A protracted North American economic shutdown could lower bid volumes due to budgetary limitations or reduced traffic on the roadways and reduced demand from our chemical customers.

•Customer access to retailers in our North American markets could impact consumer and industrial product demand.

•Potential reduced demand in our specialty crop markets in North America. As a result, our current Plant Nutrition North America volume guidance for 2020 ranges from 340,000 to 365,000 tons.

•A significant decline in global demand of crops, water conditioning products and chemical products that use our Plant Nutrition South America products could reduce demand in this segment.

For more information, see “Part II–Item 1A–Risk Factors.”

Critical Accounting Estimates

Preparation of our consolidated financial statements in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses. Management believes the most complex and sensitive judgments result primarily from the need to make estimates about matters that are inherently uncertain. Management’s Discussion and Analysis and Note 2 to the Consolidated Financial Statements included in our Annual Report on Form 10-K for the year ended December 31, 2019 describe the significant accounting estimates and policies used in preparation of our consolidated financial statements. For a further description of our critical accounting policies, see Note 1 to our Consolidated Financial Statements included in this Quarterly Report on Form 10-Q. Actual results in these areas could differ from management’s estimates.

Company Overview

Compass Minerals is a leading producer of essential minerals, including salt, sulfate of potash (“SOP”) specialty fertilizer and magnesium chloride. As of June 30, 2020, we operated 21 production and packaging facilities, including:

•The largest rock salt mine in the world in Goderich, Ontario, Canada;

•The largest dedicated rock salt mine in the U.K. in Winsford, Cheshire;

•A solar evaporation facility located in Ogden, Utah, which is both the largest SOP production site and the largest solar salt production site in the Western Hemisphere;

OTHER EXPENSES AND INCOME

COMMENTARY: THREE MONTHS ENDED JUNE 30, 2019 AND 2020

SG&A: Increased $0.1 million; Decreased 0.7 percentage points as a percentage of sales from 17.0% to 16.3%

•The increase in SG&A expense was primarily due to higher corporate incentive compensation and corporate professional service fees, which were partially offset by reduced travel and advertising expenses due to COVID-19.

Interest Expense: Increased $0.4 million to $17.2 million

•The increase was primarily due to an increase in interest rates due to the refinancing of our debt in the fourth quarter of 2019, which was partially offset by lower debt levels.

Loss (Gain) on Foreign Exchange: Increased $0.9 million from an expense of $4.1 million to expense of $5.0 million

•We realized foreign exchange losses of $5.0 million in the second quarter of 2020 compared to $4.1 million in the second quarter of 2019 due primarily to changes in translating our intercompany loans from Canadian dollars to U.S. dollars. The foreign currency swaps associated with these loans matured in the second quarter of 2020.

28

Other Income, Net: Decreased $0.1 million from income of $0.5 million to income of $0.4 million

•The decrease in other income was primarily due to lower interest income.

Income Tax Expense: Increased $5.6 million from a benefit of $4.4 million to an expense of $1.2 million

•The increase in income tax expense was primarily due to higher pretax income in the second quarter of 2020 versus the pretax loss in the second quarter of 2019 and discrete tax expense items in the second quarter of 2020.

•Our income tax provision in both periods differs from the U.S. statutory rate primarily due to U.S. statutory depletion, state income taxes, global intangible low-taxed income, foreign income, mining and withholding taxes and interest expense recognition differences for tax and financial reporting purposes.

•Our effective tax rate increased from 27% in the second quarter of 2019 to 41% in the second quarter of 2020 primarily due to the impact of discrete tax items in the second quarter of 2020 on low pretax income.

•We realized foreign exchange gains of $9.3 million in the first six months of 2020 compared to a loss of $9.0 million in the first six months of 2019 due primarily to changes in translating our intercompany loans from Canadian dollars to U.S. dollars.

Other Income, Net: Decreased $0.7 million from income of $1.0 million to income of $0.3 million

•The decrease in other income is primarily due to losses incurred in the first quarter of 2020 related to our non-qualified deferred compensation plan for certain executives and lower interest income in the current period.

Income Tax Expense: Increased $12.4 million from $0.5 million to $12.9 million

•The increase in income tax expense was primarily due to higher pretax income in the first half of 2020 versus pretax losses in the first half of 2019, partially offset by the discrete tax expense items in the first quarter of 2019.

•Our income tax provision in both periods differs from the U.S. statutory rate primarily due to U.S. statutory depletion, state income taxes, global intangible low-taxed income, foreign income, mining and withholding taxes and interest expense recognition differences for tax and financial reporting purposes.

•Our effective tax rate increased from 14% in the first half of 2019 to 31% in the first half of 2020 primarily due to the impact of discrete tax items in the first quarter of 2019.

Liquidity and Capital Resources

Historically, our cash flows from operating activities have generally been adequate to fund our basic operating requirements and ongoing debt service. We have also used cash generated from operations to fund capital expenditures which strengthen our operational position, pay dividends, fund smaller acquisitions and repay our debt. To a certain extent, our ability to meet our short- and long-term liquidity and capital needs is subject to general economic, financial, competitive, legislative, regulatory and weather conditions, effects of climate change, geological variations in our mine deposits and other factors that are beyond our control. Historically, our working capital requirements have been the highest in the fourth quarter and lowest in the second quarter. When needed, we may fund short-term working capital requirements by accessing our $300 million revolving credit facility.

We have been able to manage our cash flows generated and used across Compass Minerals to permanently reinvest earnings in our foreign jurisdictions or efficiently repatriate those funds to the U.S. As of June 30, 2020, we had $32.8 million of cash and cash equivalents (in our Consolidated Balance Sheets) that were either held directly or indirectly by foreign subsidiaries. During the fourth quarter of 2018, we revised our permanently reinvested assertion to indicate that we expect to repatriate approximately $150 million of unremitted foreign earnings on which we have recorded a $4.8 million deferred tax liability as of June 30, 2020 for foreign withholding tax and state income tax. Due to our ability to generate adequate levels of domestic cash flow on an annual basis, it is our current intention to continue to reinvest all remaining undistributed earnings of our foreign subsidiaries indefinitely. We review our tax circumstances on a regular basis with the intent of optimizing cash accessibility and minimizing tax expense. In addition, the amount of permanently reinvested earnings is influenced by, among other things, the profits generated by our foreign subsidiaries and the amount of investment in those same subsidiaries. The profits generated by our domestic and foreign subsidiaries are impacted by the transfer price charged on the transfer of our products between them. As discussed in Note 7 to our Consolidated Financial Statements, our calculated transfer price on certain products between one of our foreign subsidiaries and a domestic subsidiary has been challenged by Canadian federal and provincial governments. In the fourth quarter of 2017, we reached a federal settlement agreement with Canadian and U.S. tax authorities related to our transfer pricing issues for our 2007-2012 tax years. The recording of this settlement resulted in increased sales for our Canadian subsidiary of $85.7 million and increased offsetting expenses for our U.S. subsidiary in 2017 causing a domestic loss and significant foreign income. During 2018, in accordance with the settlement agreement, our U.S. subsidiary made intercompany cash payments of $85.7 million to our Canadian subsidiary and tax payments to Canadian taxing authorities of $17.5 million. The remaining liability was satisfied in 2019 with tax payments of $5.3 million. Corresponding tax refunds of $21.4 million were received primarily in 2019 from U.S. taxing authorities, with the remaining refund of approximately $1.6 million expected in 2020. Additionally during the fourth quarter of 2018, we reached a federal settlement agreement with Canadian and U.S. tax authorities on transfer pricing and management fees as part of an advanced pricing agreement that covers tax years 2013-2021.

33

The recording of this settlement in 2018 resulted in increased sales for our Canadian subsidiary of $106.1 million and offsetting expenses for our US subsidiary causing a domestic loss and significant foreign income in 2018. During the second quarter of 2019, in accordance with the settlement agreement, our U.S. subsidiary made intercompany cash payments of $106.1 million to our Canadian subsidiary and tax payments to Canadian taxing authorities of $29.9 million with the remaining $1.4 million of tax payments to be paid during 2020. Corresponding tax refunds of $59.7 million have been received as of June 30, 2020 from U.S. taxing authorities, of which $55 million was received during the first quarter of 2020, with the remaining $1.9 million expected in 2020. There are ongoing challenges by Canadian provincial taxing authorities regarding our transfer prices of certain products. The final resolution of these challenges may not occur for several years. We currently expect the outcome of these matters will not have a material impact on our results of operations. However, it is possible the resolution could materially impact the amount of earnings attributable to our domestic and foreign subsidiaries, which could impact the amount of permanently reinvested foreign earnings as well as future cash flows from our domestic operations. See Note 7 to our Consolidated Financial Statements for a discussion regarding our Canadian tax reassessments and settlement.

A portion of our loans in Brazil are denominated in U.S. dollars. We have entered into a foreign currency agreement whereby we agreed to swap interest and principal payments on the loans denominated in U.S. dollars for principal and interest payments denominated in Brazilian reais, the functional currency of our Brazil subsidiary. See Note 12 to our Consolidated Financial Statements for a discussion of our foreign currency agreement.

Cash and cash equivalents as of June 30, 2020 of $67.2 million, increased $32.5 million from December 31, 2019. We generated $233.9 million of operating cash flows in the first six months of 2020. In the first six months of 2020, we used cash on hand and cash flows from operations to pay $100.5 million of net long-term debt, to fund capital expenditures of $42.7 million and pay dividends on our common stock of $49.5 million.

As of June 30, 2020, we had $1.3 billion of indebtedness, consisting of $250.0 million outstanding under our 4.875% Senior Notes due 2024, $500.0 million outstanding under our 6.75% Senior Notes due 2027, $454.0 million of borrowings outstanding under our senior secured credit facilities (consisting of term loans and a revolving credit facility), including $59.0 million borrowed against our revolving credit facility, and $95.9 million of Brazilian debt (see Note 8 to our Consolidated Financial Statements for more detail regarding our debt). We had $10.4 million of outstanding letters of credit as of June 30, 2020, which reduced our revolving credit facility borrowing availability to $230.6 million.

On June 30, 2020, certain of our U.S. subsidiaries entered into a three-year committed revolving accounts receivable financing facility of up to $100 million with PNC Bank, National Association, as administrative agent and lender, and PNC Capital Markets, LLC, as structuring agent. In July 2020, we received our first loan amount of $24.0 million. See Note 15 to our Consolidated Financial Statements for more information.

Our debt service obligations could, under certain circumstances, materially affect our financial condition and impair our ability to operate our business or pursue our business strategies. As a holding company, CMI’s investments in its operating subsidiaries constitute substantially all of its assets. Consequently, our subsidiaries conduct substantially all of our consolidated operating activities and own substantially all of our operating assets. The principal source of the cash needed to pay our obligations is the cash generated from our subsidiaries’ operations and their borrowings. Our subsidiaries are not obligated to make funds available to CMI. Furthermore, we must remain in compliance with the terms of our credit agreement governing our term loans and revolving credit facility, including the total leverage ratio and interest coverage ratio, in order to make payments on our debt or pay dividends to our stockholders. We must also comply with the terms of our indenture governing our senior notes. Although we are in compliance with our debt covenants as of June 30, 2020, we can make no assurance that we will remain in compliance with these ratios nor can we make any assurance that the agreements governing the current and future indebtedness of our subsidiaries will permit our subsidiaries to provide us with sufficient dividends, distributions or loans to fund scheduled interest payments on our debt when due. If we consummate an additional acquisition, our debt service requirements could increase. Furthermore, we may need to refinance all or a portion of our indebtedness on or before maturity; however, we cannot provide assurance that we will be able to refinance any of our indebtedness on commercially reasonable terms or at all.

Sensitivity Analysis Related to EBITDA and Adjusted EBITDA

Management uses a variety of measures to evaluate our performance. While our consolidated financial statements, taken as a whole, provide an understanding of our overall results of operations, financial condition and cash flows, we analyze components of the consolidated financial statements to identify certain trends and evaluate specific performance areas. In addition to using U.S. GAAP financial measures, such as gross profit, net earnings and cash flows generated by operating activities, management uses EBITDA and Adjusted EBITDA. Both EBITDA and Adjusted EBITDA are non-GAAP financial measures used to evaluate the operating performance of our core business operations, because our resource allocation, financing methods, cost of capital and income tax positions are managed at a corporate level apart from the activities of the operating segments and our operating facilities are located in different taxing jurisdictions, which can cause considerable variation in net earnings. We also use these measures to assess our operating performance and return on capital, and to evaluate potential acquisitions or other capital projects. These measures are not calculated under U.S. GAAP and should not be considered in isolation or as a substitute for net earnings, operating earnings, cash flows or other financial data prepared in accordance with U.S. GAAP or as a measure of our overall profitability or liquidity. EBITDA and Adjusted EBITDA exclude interest expense, income taxes and depreciation and amortization, each of which are an essential element of our cost structure and cannot be eliminated. Furthermore, Adjusted EBITDA excludes other cash and non-cash items including stock-based compensation, (gain) loss on foreign exchange and other expense (income). Our borrowings are a significant component of our capital structure and interest expense is a continuing cost of debt. We are also required to pay income taxes, a required and ongoing consequence of our operations. We have a significant investment in capital assets and depreciation and amortization reflect the utilization of those assets in order to generate revenues. Consequently, any measure that excludes these elements has material limitations. While EBITDA and Adjusted EBITDA are frequently used as measures of operating performance, these terms are not necessarily comparable to similarly titled measures of other companies due to the potential inconsistencies in the method of calculation.

Recent Accounting Pronouncements

See Note 1 to our Consolidated Financial Statements for a discussion of recent accounting pronouncements.

Effects of Currency Fluctuations

Our operations outside of the U.S. are conducted primarily in Canada, Brazil and the U.K. Therefore, our results of operations are subject to both currency transaction risk and currency translation risk. We incur currency transaction risk whenever we or one of our subsidiaries enters into either a purchase or sales transaction using a currency other than the local currency of the transacting entity. With respect to currency translation risk, our financial condition and results of operations are measured and recorded in the relevant local currency and then translated into U.S. dollars for inclusion in our consolidated financial statements. Exchange rates between these currencies and the U.S. dollar have fluctuated significantly from time to time and may do so in the future. The majority of revenues and costs are denominated in U.S. dollars, with Canadian dollars, Brazilian reais and British pounds sterling also being significant. Significant changes in the value of the Canadian dollar, Brazilian reais or British pound sterling relative to the U.S. dollar could have a material effect on our financial condition.

Although inflation has not had a significant impact on our operations, our efforts to recover cost increases due to inflation may be hampered as a result of the competitive industries and countries in which we operate.

Seasonality

We experience a substantial amount of seasonality in our sales. Our sales of our salt deicing products are seasonal. Consequently, our Salt sales and operating income are generally higher in the first and fourth quarters and lower during the second and third quarters of each year. In particular, sales of highway and consumer deicing salt and magnesium chloride products vary based on the severity of the winter conditions in areas where the product is used. Following industry practice in North America, we seek to stockpile sufficient quantities of deicing salt in the second, third and fourth quarters to meet the estimated requirements for the winter season.

Our plant nutrition business is also seasonal. The strongest demand for our Plant Nutrition South America products in Brazil typically occurs during the spring planting season. As a result, we and our customers generally build inventories during the low demand periods of the year to ensure timely product availability during the peak sales season. The seasonality of this demand results in our sales volumes and net sales for our Plant Nutrition South America segment usually being the highest during the third and fourth quarters of each year (as the spring planting season begins in September in Brazil).

Item 3. Quantitative and Qualitative Disclosures About Market Risk

Our business is subject to various types of market risks that include interest rate risk, foreign currency exchange rate risk and commodity pricing risk. Management has taken actions to mitigate our exposure to commodity pricing and foreign currency exchange rate risk by entering into natural gas derivative instruments and foreign currency contracts. We may take further actions to mitigate our exposure to interest rates, exchange rates and changes in the cost of transporting our products due to variations in our contracted carriers’ cost of fuel, which is typically diesel fuel. However, there can be no assurance that our hedging activities will eliminate or substantially reduce these risks. We do not enter into any financial instrument arrangements for speculative purposes. Our market risk exposure related to these items has not changed materially since December 31, 2019.

Item 4. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

As of the end of the period covered by this Quarterly Report on Form 10-Q, an evaluation of the effectiveness of the design and operation of the Company’s disclosure controls and procedures (as defined in Rule 13a-15(e) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”)) was performed under the supervision and with the participation of the Company’s management, including the Chief Executive Officer and Chief Financial Officer. Based on that evaluation, the Company’s Chief Executive Officer and Chief Financial Officer concluded that the Company’s disclosure controls and procedures were effective as of June 30, 2020 to ensure that information required to be disclosed in the reports it files and submits under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms.

For this purpose, disclosure controls and procedures include controls and procedures designed to ensure that information that is required to be disclosed under the Exchange Act is accumulated and communicated to the Company’s management, including the Chief Executive Officer and Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosure.

Changes in Internal Control Over Financial Reporting

There has been no change in the Company’s internal control over financial reporting during the most recently completed fiscal quarter that has materially affected, or is reasonably likely to materially affect, the Company’s internal control over financial reporting.

PART II. OTHER INFORMATION

Item 1. Legal Proceedings

We are involved in the legal proceedings described in Note 7 and Note 9 to our Consolidated Financial Statements and, from time to time, various routine legal proceedings and claims arising from the ordinary course of our business. These primarily involve tax assessments, disputes with former employees and contract labor, commercial claims, product liability claims, personal injury claims and workers’ compensation claims. Management cannot predict the outcome of legal proceedings and claims with certainty. Nevertheless, management believes that the outcome of legal proceedings and claims, which are pending or known to be threatened, even if determined adversely, will not, either individually or in the aggregate, have a material adverse effect on our results of operations, cash flows or financial condition. There have been no material developments since December 31, 2019 with respect to our legal proceedings, except as described in Note 7 and Note 9 to our Consolidated Financial Statements.

Item 1A. Risk Factors

For a discussion of the risk factors applicable to Compass Minerals, please refer to Part I, Item 1A. “Risk Factors” in our Annual Report on Form 10-K for the year ended December 31, 2019, as updated and supplemented by the discussion below related to the COVID-19 pandemic. 

The COVID-19 pandemic, or other outbreaks of infectious disease or similar public health threats, could materially and adversely affect our business, financial condition and results of operations.

The recent outbreak of COVID-19, and any other outbreaks of contagious diseases or other adverse public health developments in the United States or worldwide, could have a material adverse effect on our business, financial condition and results of operations. As an essential business, we have continued producing and delivering products that support critical industries such as transportation, agriculture, chemical, food, pharmaceutical and animal nutrition. However, COVID-19 has significantly impacted economic activity and markets worldwide in 2020, and it could negatively affect our business in a number of ways. These effects could include, but are not limited to:

•Disruptions or restrictions on our employees’ ability to work effectively due to illness, travel bans, quarantines, shelter-in-place orders or other limitations could impact our business.

•Temporary closures or disruptions at our facilities or the facilities of our customers or suppliers could reduce demand for our products or affect our ability to timely meet our customer’s orders and negatively impact our supply chain. For example, we experienced lost sales in the second quarter of 2020 primarily for certain customers of our non-deicing salt products due to manufacturing outages and retail disruptions. Compliance with new governmental regulations, such as social distancing regulations, could increase our operational costs. Our mining and manufacturing facilities in North America and Brazil remained in operation throughout the first half of 2020; however, operations at our U.K. salt mine were idled near the end of March 2020 due to the mild 2019-2020 winter weather experienced in that market, along with U.K. government guidance on COVID-19 preventative measures, with operations resuming in mid-May 2020 using a gradual ramp up. In addition, we have incurred increased costs related to health and safety precautions we have put in place at our facilities, such as increasing sanitation of offices and common areas within our facilities.

•Our mining and manufacturing facilities rely on raw materials and components provided by our suppliers. If the ongoing quarantining or similar measures cause delays along our supply chain, we could experience a mining or manufacturing slow-down or seek to obtain alternate sources of supply, which may not be available or may be more expensive. Disruptions to our supply chain and business operations, or to our suppliers’ or customers’ supply chains and business operations, could include disruptions from the closure of supplier and manufacturer facilities, interruptions in the supply of raw materials and components, personnel absences, or restrictions on the shipment of our or our suppliers’ or customers’ products, any of which could have adverse ripple effects on our business.

•Global health concerns, such as COVID-19, could result in social, economic and labor instability in the countries and localities in which we or our suppliers and customers operate. Any of these uncertainties could have a material adverse effect on our business, financial condition or results of operations.

•The failure of third parties on which we rely, including our suppliers, customers, contractors, commercial banks and external business partners, to meet their respective obligations to the Company, or significant disruptions in their ability to do so, which may be caused by their own financial or operational difficulties, could have an adverse impact on our business, financial condition or results of operations.

•Remote work arrangements for our employees could strain our technology resources and introduce operational risks, including heightened cybersecurity risk. Remote working environments may be less secure and more

38

susceptible to hacking attacks, including phishing and social engineering attempts that seek to exploit the COVID-19 pandemic. These risks could also impact the third parties on which we rely.

•The COVID-19 pandemic has significantly increased economic and demand uncertainty and has led to disruption and volatility in the global credit and financial markets, which increases the cost of capital and adversely impacts access to capital for both the Company and our customers and suppliers. Disruption and volatility in the global and financial markets or other factors may also cause adverse fluctuations in foreign currency exchange rates, particularly an increase in the value of the U.S. dollar against the Canadian dollar, the Brazilian reais or the U.K. pound sterling, which could negatively affect our business, financial condition and reported results of operations.

The impact of COVID-19 may also exacerbate other risks discussed in Part I, Item 1A. “Risk Factors” in our Annual Report on Form 10-K for the year ended December 31, 2019, any of which could have a material adverse effect on us. The extent to which the COVID-19 pandemic, or other outbreaks of disease or similar public health threats, materially and adversely impact our business, financial condition and results of operations is highly uncertain and will depend on future developments. Such developments may include the geographic spread and duration of the virus, the severity of the disease and the actions that may be taken by various governmental authorities and other third parties in response to the outbreak. In addition, how quickly, and to what extent, normal economic and operating conditions can resume cannot be predicted, and the resumption of normal business operations may be delayed or constrained by lingering effects on our suppliers, third-party service providers and customers.

Item 2. Unregistered Sales of Equity Securities and Use of Proceeds

(a) None.

(b) None.

(c)  Issuer Purchases of Equity Securities

The Company withheld 14,627 shares with a fair value of $0.7 million related to the vesting of restricted stock units during the first six months of 2020. The fair value of the shares were valued at the closing price at the vesting date and represent the employee tax withholding for the employee’s compensation. These shares are not considered common stock repurchases under the Company’s equity compensation plans.

Item 3. Defaults Upon Senior Securities

None.

Item 4. Mine Safety Disclosures

EX-10.1

Exhibit 10.1

Non-Employee Director Compensation Policy

Effective May 14, 2020

Non-employee members of the board of directors (the “Board”) of Compass Minerals International, Inc. (the “Company”) will be eligible to receive compensation as set forth in this Non-Employee Director Compensation Policy (this “Policy”). The compensation described in this Policy will be paid, granted or issued, as applicable, to each member of the Board who is not an employee of the Company or any parent or subsidiary of the Company (each, a “Director”). This Policy is effective May 14, 2020 (the “Effective Date”) and will remain in effect until it is revised or rescinded by further action of the Board. As of the Effective Date, this Policy will replace and supersede, in its entirety, the Company’s Non-Employee Director Compensation Policy, effective January 1, 2017 (the “2017 Policy”).

A.Cash Compensation

1.Annual Retainers and Other Fees. Directors may receive retainers and other fees (the “Cash Compensation”), payable in cash (subject to Section C), as compensation for their service as a Director, as the Board may determine from time to time which may include, without limitation, an annual retainer, committee service fees, committee chair fees, chairman of the board fees, lead independent director fees and meeting fees.   

2.Payment

1.Payment Date. The Cash Compensation will be earned on a quarterly basis based on a calendar quarter and will be paid by the Company in arrears.

2.Partial Service. In the event a Director does not serve as a Director (or in an applicable position on the Board) for an entire calendar quarter (but serves for a portion of the quarter), such Director will receive a prorated portion of the Cash Compensation otherwise payable to him or her for such calendar quarter, with such prorated portion determined by multiplying the Cash Compensation that would otherwise be payable by a fraction, the numerator of which is the number of days during which the Director serves as a Director or in an applicable position during the applicable calendar quarter and the denominator of which is the number of days in the applicable calendar quarter.

B.Equity Compensation

1.Equity Awards. Directors may receive equity awards as compensation for service as the Board may determine from time to time (“Equity Compensation”). The awards will be granted under, and be subject to the, terms and provisions of the Company’s 2020 Incentive Award Plan or any other applicable Company equity incentive plan then-maintained by the Company (the “Equity Plan”). All applicable terms of the Equity Plan apply to this Policy as if fully set forth herein, and all equity grants hereunder are subject in all respects to the terms of the Equity Plan. The Board will establish the dollar amount of the Equity Compensation payable to Directors (the “Annual Equity Award Value”).

2.Payment

a.Number of Shares. Directors will receive Equity Compensation in the form of restricted stock units of the Company (“RSUs”). The number RSUs awarded to a Director will be determined by dividing (i) the Annual Equity Award Value by (ii) the closing market price per share of the Common Stock on the date of grant, or on the next trading day if such date

was not a trading day, as reported on the New York Stock Exchange Composite Transactions listing (the “Fair Market Value”).

b.RSU Account. The Company will maintain a separate bookkeeping account (the “RSU Account”) to reflect the RSUs (whether issued by the Company under this Policy or otherwise) issued to each Director.

c.Fractional Shares. Only whole shares will be issued in settlement of RSUs; fractional shares will be eliminated by rounding up to the next whole number.

3.Grant Date. As of the date of any annual meeting of the Company’s stockholders that occurs during or following 2020 (an “Annual Meeting”), each Director who following such Annual Meeting will continue to serve as a non-employee Director immediately following such Annual Meeting will be automatically granted, on the date of such Annual Meeting, the number of RSUs set forth in Section B(2)(a) (the “RSU Award”).

4.Vesting.

i.The RSU Award will vest on the earlier of (i) the day immediately preceding the date of the first Annual Meeting following the date of grant that is at least 50 weeks from the date of grant and (ii) the first anniversary of the date of grant, subject to the Director continuing in service on the Board through the applicable vesting date (other than the circumstance set forth in Sections B(4)(b) and B(4)(c)). Shares underlying the RSU Award will be distributed as soon as reasonably practicable after, and in any event within thirty days following the Annual Meeting at which it vests.

ii.In the event of a Director’s cessation of service due to death or disability (as determined in good faith by the Board), the RSU Award will become fully vested as of the date of such cessation of service.

iii.Partial Service. Except as set forth in the preceding Section B(4)(b), in the event a Director does not serve as a Director (or in an applicable position on the Board) for the entire vesting period (but serves for a portion of such period), a prorated portion of the RSU Award will become vested, with such prorated portion determined by multiplying the RSU Award by a fraction, the numerator of which is the number of days during which the Director serves as a Director or in the applicable position during the applicable year and the denominator of which is 365.

C.Payment Elections and Deferrals

1.Cash Compensation. Notwithstanding Section A, Directors may elect in accordance with Section C(3) that an amount equal to all or a portion of the Cash Compensation be paid:

a.In the form of Deferred Stock Units, in which case the dollar value of any such amount will be paid pursuant to Section C(4);

b.In the form of shares of Common Stock, in which case the Director will receive shares of Common Stock with an aggregate Fair Market Value equal to the dollar value of any such amount; or

c.Subject to the Board’s approval, under other deferred compensation plans or programs established by the Board.

2

|

2.Equity Compensation. Directors may elect in accordance with Section C(3) that an amount equal to all or a portion of the Equity Compensation to be paid in the form of Deferred Stock Units. The dollar value of any such amount to be paid in the form of Deferred Stock Units will be paid pursuant to Section C(4).

3.Elections; Notification Requirements. If a Director desires to defer receipt of all or a portion of his or her Cash Compensation or Equity Compensation or otherwise make an election pursuant to this Section C, he or she must make an election (a “Deferral Election”) by delivering an election form to the Secretary of the Company. Any initial Deferral Election must satisfy the requirements of Section 409A of the Internal Revenue Code, as amended (the “Code”), to the extent applicable. Any initial Deferral Election must be made not later than December 31 of the calendar year immediately preceding the calendar year of service by delivering an election form to the Secretary of the Company. Notwithstanding the foregoing, any newly-appointed or elected Director may make a Deferral Election no later than thirty days after such Director first becomes eligible to participate in this Policy and such Deferral Election may only be made with respect to Cash Compensation and Equity Compensation payable for services to be performed during or after the period commencing on the first day of the first full calendar quarter immediately following the date of such Deferral Election. Once a Deferral Election is made, it may be revoked and changed only for future years. Each Deferral Election will carry over to Cash Compensation and Equity Compensation in subsequent plan years unless and until terminated.

4.Deferred Stock Units

a.Payment

i.Deferred Stock Account. The Company will maintain a separate bookkeeping account (the “Deferred Stock Account”) to reflect the deferred stock units (whether issued by the Company under this Policy or otherwise, “Deferred Stock Units”) issued to each Director.

ii.Number of Units.

1.With respect to the Cash Compensation that is being deferred in the form of Deferred Stock Units, the number of Deferred Stock Units issued to a Director will be determined by dividing the Cash Compensation that the Director has elected to defer by the Fair Market Value on the date of issuance.

2.With respect to the Equity Compensation that is being deferred in the form of Deferred Stock Units, the number of Deferred Stock Units issued to a Director will be determining by dividing the Equity Compensation that the Director has elected to defer by the Fair Market Value on the date of issuance.

iii.Issuance Date.

1.With respect to the Cash Compensation that is being deferred in the form of Deferred Stock Units, such Deferred Stock Units will be earned on a quarterly basis based on a calendar quarter and the date of issuance will be the last business day of each calendar quarter, with distributions to be made pursuant to Section C(4)(b).

2.With respect to the Equity Compensation that is being deferred in the form of Deferred Stock Units, such Deferred Stock Units will be earned on an annual basis beginning on the Annual Meeting and the date of issuance will be the

3

|

subsequent Annual Meeting, with distributions to be made pursuant to Section C(4)(b).

iv.Partial Service – Cash Compensation. In the event a Director does not serve as a Director (or in an applicable position on the Board) for an entire calendar quarter (but serves for a portion of the quarter), such Director will receive a prorated portion of Deferred Stock Units otherwise payable to him or her for such calendar quarter as Cash Compensation, with such prorated portion of Deferred Stock Units determined by multiplying the Annual Equity Award Value that the Director has elected to defer by a fraction, the numerator of which is the number of days during which the Director serves as a Director or in the applicable position during the applicable calendar quarter and the denominator of which is the number of days in the applicable calendar quarter.

i.Distribution. Deferred Stock Units will be distributed to Directors in the form of shares of Common Stock, with each Deferred Stock Unit equal to one share of Common Stock. Such distribution will be made in whole shares of Common Stock, to be specified pursuant to a fixed schedule under the applicable Deferral Election pursuant to Section C(3) and subject to compliance with Section 409A of the Code. All distributions will be made no later than 5 business days following the elected payment date.

ii.Vesting.

i.With respect to the Cash Compensation that is being deferred in the form of Deferred Stock Units, such Deferred Stock Units will be immediately vested.

ii.With respect to the Equity Compensation that is being deferred in the form of Deferred Stock Units, such Deferred Stock Units will vest in accordance with Section B(4), including, without limitation, Sections B(4)(b) and B(4)(c).

iii.Voting Rights. Director will have no voting rights with respect to any RSUs or Deferred Stock Units.

iv.Dividend Equivalents

i.Right to Receive. Each RSU will carry with it a right to receive dividend equivalents which will be payable in the form of cash. Each Deferred Stock Unit credited to a Director’s Deferred Stock Account will carry with it a right to receive dividend equivalents which will be paid in the form of additional Deferred Stock Units. The Dividend Equivalent rights associated with Deferred Stock Units will remain outstanding until the delivery to the Director of the shares of Common Stock underlying such Deferred Stock Unit.

ii.Issuance Date. Deferred Stock Units issued with respect to dividend equivalents will be issued as of the date the Company pays any dividend (whether in cash or in kind) on shares of Common Stock.

iii.Number of Units. The number of Deferred Stock Units issued to a Director with respect to dividend equivalents will be determined by dividing (A) the aggregate dollar value of the dividend that would have been payable with respect to the RSU credited to a Director’s RSU Account immediately prior to the dividend payment date by (B) the Fair Market Value on the date of issuance.

4

|

iv.Distribution. Deferred Stock Units issued with respect to dividend equivalents will be distributed to Directors pursuant to Section C(4)(b) using the fixed schedule under the applicable Deferral Election for the year in which such Deferred Stock Units were issued.

v.Fractional Shares. Only whole shares will be issued in settlement of dividend equivalents; fractional shares will be eliminated by rounding down to the previous whole number.

v.Payment Following Change of Control. Notwithstanding anything in this Policy to the contrary or any election made by any Director, if a “change in control event” within the meaning of Section 409A of the Code occurs, any RSU or Deferred Stock Unit credited to a Director’s Deferred Stock Account as of such Change of Control will be distributed in a single lump sum to the Director (or, as applicable, his or her beneficiary) immediately following the Change of Control.

D.General

1.Unfunded Obligation.This Policy is designed and will be administered at all times as an unfunded arrangement and each Director will be treated as an unsecured general creditor and will have no beneficial ownership of any assets of the Company.

2.Taxes. Directors will be solely responsible for any federal, state or other taxes imposed in connection with Cash Compensation and Equity Compensation (including RSUs and Deferred Stock Units) and each Director authorizes the Company or any of its subsidiaries to make any withholding for taxes which the Company or any subsidiary deems, in their sole discretion, necessary or desirable in connection therewith.

3.Acceleration of Payment to Pay State, Local or Foreign Taxes. The time or schedule of any distribution or payment of any RSUs or Deferred Stock Units or any other award that constitutes non-qualified deferred compensation for purposes of Section 409A of the Code will not be accelerated, except as otherwise permitted under Section 409A of the Code, including without limitation, Treasury Regulation 1.409A-3(j). Subject to the foregoing, the Company will accelerate the payment of a portion of the shares of RSUs or Deferred Stock Units credited to a Director’s RSU Account or Deferred Stock Account for the sole purpose of allowing such Director to pay applicable state, local and foreign taxes relating to such Deferred Stock Units consistent with Section 409A of the Code. Accelerated payment will be limited to the amount of taxes due as a result of such Director’s participation in the Company’s deferred compensation program, all as certified by the Director’s personal tax advisor. Directors will be solely responsible for any tax consequences relating to or resulting from the accelerated payment from his or her RSU Account or Deferred Stock Account.

4.Amendments; Etc. This Policy may be amended, modified or terminated by the Board at any time in its sole discretion. To the extent that the Company’s Annual Meeting schedule is materially changed from the schedule in effect on the Effective Date, this Policy may be equitably adjusted by the Company in connection with such change. The terms and conditions of this Policy supersede any prior compensation arrangements for service as a member of the Board between the Company and any of its Directors and between any subsidiary of the Company and any of its Directors.

5.Governing Law. This Policy and any agreements or documents hereunder will be administered, construed and enforced in accordance with the laws of the State of Delaware without regard to conflicts of laws thereof.

Mine Safety Disclosure

We understand that to prevent employee and contractor injuries, we must approach safety excellence from many directions at once. We have developed a three-pronged approach towards world class safety performance. This approach consists of (1) setting a high standard of risk mitigation, (2) having robust safety management systems, and (3) supporting a culture of full engagement and personal accountability at all levels of the organization.

We continuously monitor our safety performance by assessing injury and non-injury incidents (e.g., near misses/near hits) as well as key performance indicators. We believe our approach to safety excellence will help us deliver on our commitment to our employees, contractors, their families and our customers to provide a safe working environment.

Mine Safety Data

A subsidiary of Compass Minerals International, Inc. owns and operates the Cote Blanche mine, an underground salt mine located in St. Mary Parish, Louisiana. The Cote Blanche mine is subject to regulation by the Mine Safety and Health Administration (“MSHA”) under the Federal Mine Safety and Health Act of 1977, as amended (the “Mine Act”).

MSHA is required to regularly inspect the Cote Blanche mine and issue a citation, or take other enforcement action, if an inspector or authorized representative believes that a violation of the Mine Act or MSHA’s standards or regulations has occurred. MSHA is required to propose a civil penalty for each alleged violation that it cites.

We have the option to contest any enforcement action or related penalty we receive before the Federal Mine Safety and Health Review Commission. As a result of this process, an enforcement action may be modified or vacated and any civil penalty proposed by MSHA for an alleged violation may be increased, reduced or eliminated. However, under the Mine Act, we are required to abate (or correct) each alleged violation within a specified time period, regardless of whether we contest the alleged violation.

The table below sets forth information for the quarterly period ended June 30, 2020 concerning certain mine safety violations and other regulatory matters pursuant to requirements under the Dodd-Frank Wall Street Reform and Consumer Protection Act and Securities and Exchange Commission rules and regulations. The information only reflects our U.S. mining operations, as these requirements do not apply to mining operations outside the U.S.

Accounting Policies [Abstract]

Accounting Policies and Basis of Presentation

Accounting Policies and Basis of Presentation:

Compass Minerals International, Inc. (“CMI”), through its subsidiaries (collectively, the “Company”), is a leading producer of essential minerals that solve nature’s challenges, including salt for winter roadway safety and other consumer, industrial and agricultural uses, specialty plant nutrition minerals that improve the quality and yield of crops, and specialty chemicals for water treatment and other industrial processes. The Company’s principal products are salt, consisting of sodium chloride and magnesium chloride; plant nutrients, consisting of sulfate of potash (“SOP”), secondary nutrients and micronutrients; and specialty chemicals. The Company also provides records management services to businesses located in the United Kingdom (the “U.K.”). The Company’s production sites are located in the United States (“U.S.”), Canada, Brazil and the U.K. Except where otherwise noted, references to North America include only the continental U.S. and Canada, and references to the U.K. include only England, Scotland and Wales. References to “Compass Minerals,” “our,” “us” and “we” refer to CMI and its consolidated subsidiaries.

CMI is a holding company with no significant operations other than those of its wholly-owned subsidiaries. The consolidated financial statements include the accounts of CMI and its wholly-owned subsidiaries. All significant intercompany balances and transactions have been eliminated in consolidation.

The Company uses the equity method of accounting for equity securities when it has significant influence or when it has more than a minor ownership interest or more than minor influence over an investee’s operations but does not have a controlling financial interest. Initial investments are recorded at cost (including certain transaction costs) and are adjusted by the Company’s share of the investees’ undistributed earnings and losses.

The accompanying unaudited consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”) for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by U.S. GAAP for complete financial statements. These unaudited consolidated financial statements should be read in conjunction with the consolidated financial statements of the Company for the year ended December 31, 2019, as filed with the Securities and Exchange Commission (“SEC”) in its Annual Report on Form 10-K. In the opinion of management, all adjustments, consisting of normal recurring adjustments considered necessary for a fair presentation, have been included.

The Company experiences a substantial amount of seasonality in its sales with respect to its deicing salt products. As a result, sales and operating earnings are generally higher in the first and fourth quarters and lower during the second and third quarters of each year. In particular, sales of highway and consumer deicing salt and magnesium chloride products vary based on the severity of the winter conditions in areas where the products are used. Following industry practice in North America and the U.K., the Company seeks to stockpile sufficient quantities of deicing salt throughout the second, third and fourth quarters to meet the estimated requirements for the upcoming winter season. Production of deicing salt can also vary based on the severity or mildness of the preceding winter season. Due to the seasonal nature of the deicing product lines, operating results for the interim periods are not necessarily indicative of the results that may be expected for the full year.

The Company’s plant nutrition business is also seasonal. For example, the strongest demand for the Company’s plant nutrition products in Brazil typically occurs during the spring planting season. As a result, the Company and its customers generally build inventories during the low demand periods of the year to ensure timely product availability during the peak sales season. The seasonality of this demand results in the Company’s sales volumes and operating income for the Plant Nutrition South America segment usually being the highest during the third and fourth quarters of each year (as the spring planting season begins in September in Brazil).

Significant Accounting Policies

The Company’s significant accounting policies are detailed in “Note 2 – Summary of Significant Accounting Policies” within Item 8 of the Company’s Annual Report on Form 10-K for the year ended December 31, 2019.

Recent Accounting Pronouncements

In January 2017, the Financial Accounting Standards Board (“FASB”) issued guidance to simplify the accounting for goodwill impairment. The guidance removes Step 2 of the goodwill impairment test, which requires a hypothetical purchase price

allocation. A goodwill impairment will now be the amount by which a reporting unit’s carrying value exceeds its fair value, not to exceed the carrying amount of goodwill. All other goodwill impairment guidance remains largely unchanged. The adoption of this guidance on January 1, 2020 did not have an impact on the Company’s consolidated financial statements.

On January 1, 2020, the Company adopted guidance issued by the FASB related to credit losses for financial instruments, which replaces the incurred loss methodology with a current expected credit loss methodology (“CECL”). The Company has determined that its trade receivables are the only financial instrument that is within scope of this CECL guidance. The CECL methodology requires financial assets to be recorded at the net amount expected to be collected over the lifetime of the asset such that the estimated losses are accrued on the day the asset is acquired. The CECL methodology also requires financial assets to be aggregated and evaluated within pools with similar risk characteristics.

The Company has recorded an allowance on its trade receivables based on historical loss rates modified to consider supportable forecasts related to customer-specific and macroeconomic factors. For instance, the Company’s 2020 allowance for doubtful accounts considered the potential impact that the coronavirus pandemic could have on the collectability of its outstanding receivables. The Company’s customer pools are comprised of North American highway deicing customers, North American consumer and industrial customers, Plant Nutrition North America customers, Plant Nutrition South America customers and customers whose outstanding receivable balances have been sent to collections. Customers grouped within these pools have similar risk characteristics. The Company’s allowance for doubtful accounts consists of estimates of expected credit losses and accruals for returns and allowances. At the transition date of January 1, 2020, the implementation of CECL had an immaterial impact of less than $0.1 million on the Company’s consolidated financial statements. Under CECL, the Company had an allowance for doubtful accounts of $9.4 million and $8.2 million as of January 1, 2020, and June 30, 2020, respectively.

Revenue Recognition

Revenue from Contract with Customer [Abstract]

Revenue Recognition

Revenue Recognition:

Nature of Products and Services

The Company’s Salt segment products include salt and magnesium chloride for use in road deicing and dust control, food processing, water softeners, and agricultural and industrial applications. The Company’s plant nutrition products include SOP, secondary nutrients, micronutrients and chemicals for the industrial chemical industry. In the U.K., the Company operates a records management business utilizing excavated areas of the Winsford salt mine with one other location in London, England.

Identifying the Contract

The Company accounts for a customer contract when there is approval and commitment from both parties, the rights of the parties and payment terms are identified, the contract has commercial substance and collectability of consideration is probable.

Identifying the Performance Obligations

At contract inception, the Company assesses the goods and services it has promised to its customers and identifies a performance obligation for each promise to transfer to the customer a distinct good or service (or bundle of goods or services). Determining whether products and services are considered distinct performance obligations that should be accounted for separately or aggregated together may require significant judgment.

Identifying and Allocating the Transaction Price

The Company’s revenues are measured based on consideration specified in the customer contract, net of any sales incentives and amounts collected on behalf of third parties such as sales taxes. In certain cases, the Company’s customer contracts may include promises to transfer multiple products and services to a customer. For multiple-element arrangements, the Company generally allocates the transaction price to each performance obligation in proportion to its stand-alone selling price.

When Performance Obligations Are Satisfied

The vast majority of the Company’s revenues are recognized at a point in time when the performance obligations are satisfied based upon transfer of control of the product or service to a customer. To determine when the control of goods is transferred, the Company typically assesses, among other things, the shipping terms of the contract, as shipping is an indicator of transfer of control. Some of the Company’s products are sold when the control of the goods transfers to the customer at the time of shipment. There are also instances when the Company provides shipping services to deliver its products. Shipping and handling costs that occur before the customer obtains control of the goods are deemed to be fulfillment activities and are accounted for as fulfillment costs. The Company recognizes shipping and handling costs that are incurred after the customer obtains control of the goods as fulfillment costs which are accrued at the time of revenue recognition.

Significant Payment Terms

The customer contract states the final terms of the sale, including the description, quantity and price of each product or service purchased. Payment is typically due in full within 30 days of delivery. The Company does not adjust the consideration for the effects of a significant financing component if the Company expects, at contract inception, that the period between when the good or service is transferred to the customer and when the customer pays for that good or service will be one year or less.

Refunds, Returns and Warranties

The Company’s products are generally not sold with a right of return and the Company does not generally provide credits or incentives, which may be required to be accounted for as variable consideration when estimating the amount of revenue to be recognized. The Company uses historical experience to estimate accruals for refunds due to manufacturing or other defects.

See Note 10 for disaggregation of revenue by segment, type and geographical region.

Leases

Leases [Abstract]

Leases

Leases:

In February 2016, the FASB issued guidance which requires lessees to recognize on their balance sheet a right-of-use asset which represents a lessee’s right to use the underlying asset and a lease liability which represents a lessee’s obligation to make lease payments for the right to use the asset. In addition, the guidance requires expanded qualitative and quantitative disclosures. The Company adopted this guidance beginning in the first quarter of 2019, using a modified retrospective transition method, which required the cumulative effect of this change in accounting of $0.1 million to be recorded as an adjustment to beginning retained earnings. The Company elected the package of transition provisions available for existing contracts, which allowed entities to carryforward the historical assessment of whether the contract contained a lease and the lease classification.

The Company enters into leases for warehouses and depots, rail cars, vehicles, mobile equipment, office space and certain other types of property and equipment. The Company determines whether an arrangement is or contains a lease at the inception of the contract. The right-of-use asset and lease liability are recognized based on the present value of the future minimum lease payments over the estimated lease term. Lease expense for minimum lease payments is recognized on a straight-line basis over the lease term. The Company estimates its incremental borrowing rate for each lease based upon the estimated lease term, the type of asset and the location of the leased asset. The most significant judgments in the application of the FASB guidance include whether a contract contains a lease and the lease term.

Leases with an initial term of 12 months or less are not recorded on the Company’s Consolidated Balance Sheets. The Company recognizes lease expense for these short-term leases on a straight-line basis over the lease term. Many of the Company’s leases include one or more options to renew and extend the initial lease term. The exercise of lease renewal options is generally at the Company’s discretion. The lease term includes renewal periods in only those instances in which the Company determines it is reasonably assured of renewal.

The depreciable life of assets and leasehold improvements are limited by the expected lease term, unless there is a transfer of title or purchase option reasonably certain of exercise. In these instances, the assets are depreciated over the useful life of the asset.

The Company has elected the practical expedient available under the FASB guidance to not separate lease and nonlease components on all of its lease categories. As a result, many of the Company’s leases include variable payments for services (such as handling or storage) or payments based on the usage of the asset. In addition, certain of the Company’s lease agreements include rental payments that are adjusted periodically for inflation. The Company’s lease agreements do not contain any material residual value guarantees or any material restrictive covenants. The Company’s sublease income is immaterial.

Income Tax Disclosure [Abstract]

Income Taxes

Income Taxes:

The Company’s effective income tax rate differs from the U.S. statutory federal income tax rate primarily due to U.S. statutory depletion, state income taxes (net of federal tax benefit), foreign income, mining and withholding taxes, global intangible low-taxed income and interest expense recognition differences for book and tax purposes.

The Company had $11.4 million and $18.8 million as of June 30, 2020 and December 31, 2019, respectively, of gross foreign federal net operating loss (“NOL”) carryforwards that have no expiration date, $1.3 million and $1.7 million, respectively, of gross foreign federal NOL carryforwards which expire beginning in 2033 and $0.2 million and $0.3 million, respectively, of net operating tax-effected state NOL carryforwards which expire beginning in 2027.

Canadian provincial tax authorities have challenged tax positions claimed by one of the Company’s Canadian subsidiaries and have issued tax reassessments for years 2002-2015. The reassessments are a result of ongoing audits and total $127.4 million, including interest, through June 30, 2020. The Company disputes these reassessments and will continue to work with the appropriate authorities in Canada to resolve the dispute. There is a reasonable possibility that the ultimate resolution of this dispute, and any related disputes for other open tax years, may be materially higher or lower than the amounts the Company has reserved for such disputes. In connection with this dispute, local regulations require the Company to post security with the tax authority until the dispute is resolved. The Company has posted collateral in the form of a $93.7 million performance bond and has paid $36.3 million to the Canadian tax authorities (most of which is recorded in other assets in the Consolidated Balance Sheets).

The Company expects that it will be required by local regulations to provide security for additional interest on the above unresolved disputed amounts and for any future reassessments issued by these Canadian tax authorities in the form of cash, letters of credit, performance bonds, asset liens or other arrangements agreeable with the tax authorities until the disputes are resolved.

The Company expects that the ultimate outcome of these matters will not have a material impact on its results of operations or financial condition. However, the Company can provide no assurance as to the ultimate outcome of these matters, and the impact could be material if they are not resolved in the Company’s favor. As of June 30, 2020, the Company believes it has adequately reserved for these reassessments.

Additionally, the Company has other uncertain tax positions as well as assessments and disputed positions with taxing authorities in its various jurisdictions, which are consistent with those matters disclosed in the Company’s Annual Report on Form 10-K for the year ended December 31, 2019.

Settlements

In the fourth quarter of 2017, the Company, the Canadian Revenue Authority (“CRA”) and the U.S. Internal Revenue Service (“IRS”) reached a settlement agreement on transfer pricing issues for the Company’s 2007-2012 tax years. As a result of this settlement agreement, the Company recognized $13.8 million of tax expense in its 2017 Consolidated Statements of Operations related to the Company’s Canadian tax positions for the years 2007-2016. The recording of this settlement resulted in increased sales for the Company’s Canadian subsidiary of $85.7 million and increased offsetting expenses for the Company’s U.S. subsidiary in 2017 causing a domestic loss and significant foreign income. During 2018, in accordance with the settlement agreement, the Company’s U.S. subsidiary made intercompany cash payments of $85.7 million to its Canadian subsidiary and tax payments to Canadian taxing authorities of $17.5 million. The remaining liability was satisfied in 2019 with tax payments of $5.3 million. Corresponding tax refunds of $21.4 million were received primarily in 2019 from U.S. taxing authorities, with the remaining refund of approximately $1.6 million expected in 2020 (recorded in other current assets in the Consolidated Balance Sheets).

In the fourth quarter of 2018, the Company, the CRA and the IRS reached a settlement agreement on transfer pricing and management fees as part of an advanced pricing agreement that covers tax years 2013-2021. The tax expense was previously recognized in 2017, however the recording of this settlement resulted in increased sales for the Company’s Canadian subsidiary of $106.1 million and offsetting expenses for the Company’s U.S. subsidiary in 2018 causing a domestic loss and significant foreign income. During 2019, in accordance with the settlement agreement, the Company’s U.S. subsidiary made intercompany cash payments of $106.1 million to its Canadian subsidiary and tax payments to Canadian taxing authorities of $29.9 million, with the remaining $1.4 million of tax payments to be paid during 2020. Corresponding tax refunds of $59.7 million have been received as of June 30, 2020 from U.S. taxing authorities, of which $55.0 million was received during the first quarter of 2020, with the remaining $1.9 million expected in 2020 (recorded in other current assets in its Consolidated Balance Sheets).

In the first quarter of 2020, the Company entered into three loans totaling $20.0 million which mature between February 2021 and March 2022, respectively. Two of the loans were denominated in Brazilian reais and one loan was denominated in euros. In connection with the loan denominated in euros, the Company entered into a swap to exchange principal and interest payments

denominated in euros to Brazilian reais (see Note 12). These loans bear interest ranging from 143% - 150% of CDI. As of June 30, 2020, the weighted average interest rate of all the Company’s outstanding debt was approximated 5.49%.

During the first quarter of 2020, the Company sold approximately $3.4 million of Brazilian receivables for $3.3 million. The proceeds of the transaction were used to maintain liquidity for working capital needs. The Company is contingently liable for up to 20% of the sale balance up to $0.7 million if the banks are unable to collect on these accounts. See Note 15 for discussion of the Company’s securitization of a portion of its U.S. trade receivables.

As of June 30, 2020, the term loans and revolving credit facility under the Company’s credit agreement were secured by substantially all existing and future U.S. assets, the Goderich mine in Ontario, Canada and capital stock of certain subsidiaries.

Commitments and Contingencies

Commitments and Contingencies:

The Wisconsin Department of Agriculture, Trade and Consumer Protection (“DATCP”) and the Wisconsin Department of Natural Resources (“DNR”) have information indicating that agricultural chemicals are present within the subsurface area of the Company’s property located in Kenosha, Wisconsin. The agricultural chemicals were used by previous owners and operators of the site. None of the identified chemicals have been used in association with the Company’s operations since it acquired the property in 2002. DATCP and DNR have directed the Company to conduct further investigations into the environmental conditions at the Kenosha property. The Company continues on-property investigations and has provided the findings to DATCP and DNR as they have become available. All investigations and mitigation activities to date, and any potential future remediation work, are being conducted under the Wisconsin Agricultural Chemical Cleanup Program, which provides for reimbursement of some of the costs.

The Company conducts business operations in several countries and is subject to various federal and local labor, social security, environmental and tax laws. While the Company believes it complies with such laws, they are complex and subject to interpretation. In addition to the tax assessments discussed in Note 7, the Company’s Brazilian subsidiaries are party to administrative tax proceedings and claims which totaled $7.5 million and $15.8 million as of June 30, 2020 and December 31, 2019, respectively, and relate primarily to value added tax, state tax (ICMS) and social security tax (PIS and COFINS) assessments. The Company has assessed the likelihood of a loss at less than probable and therefore, has not established a reserve for these matters. The Company also assumed liabilities for labor-related matters in connection with the 2016 acquisition of Compass Minerals South America, which are primarily related to compensation, labor benefits and consequential tax claims that totaled $4.2 million and $5.6 million as of June 30, 2020 and December 31, 2019, respectively. The Company believes the maximum exposure for these other labor matters totaled approximately $18 million and $25 million as of June 30, 2020 and December 31, 2019, respectively.

The Division of Enforcement of the SEC is investigating the Company’s disclosures concerning the operation of the Goderich mine. The Company has cooperated with this investigation and will continue to do so. While it is not possible to predict the timing or the outcome of the SEC inquiry, the Company believes that this matter will not have a material impact on its results of operation, cash flows or financial position.

The Company is also involved in legal and administrative proceedings and claims of various types from the ordinary course of the Company’s business.

Management cannot predict the outcome of legal claims and proceedings with certainty. Nevertheless, management believes the outcome of legal proceedings and claims, which are pending or known to be threatened, even if determined adversely, will not, individually or in the aggregate, have a material adverse effect on the Company’s results of operations, cash flows or financial position.

Stockholders' Equity and Equity Instruments

6 Months Ended

Jun. 30, 2020

Equity [Abstract]

Stockholders' Equity and Equity Instruments

Stockholders’ Equity and Equity Instruments:

In May 2020, the Company’s stockholders approved the 2020 Incentive Award Plan (the “2020 Plan”), which authorizes the issuance of 2,977,933 shares of Company common stock. Since the date the 2020 Plan was approved, the Company ceased issuing equity awards under the 2015 Incentive Award Plan (as amended, the “2015 Plan”). Since the approval of the 2015 Plan in May 2015, the Company ceased issuing equity awards under the 2005 Incentive Award Plan (as amended, the “2005 Plan”). The 2005 Plan, 2015 Plan and 2020 Plan allow for grants of equity awards to executive officers, other employees and directors, including restricted stock units (“RSUs”), performance stock units (“PSUs”), stock options and deferred stock units. The grants occur following approval by the compensation committee of the Company’s board of directors, with the amount and terms communicated to employees shortly thereafter.

Options

Most of the stock options granted under the 2005 Plan and 2015 Plan vest ratably, in tranches, over a four-year service period. Unexercised options expire after seven years. Options do not have dividend or voting rights. Upon vesting, each option can be exercised to purchase one share of the Company’s common stock. The exercise price of options is equal to the closing stock price on the grant date.

To estimate the fair value of options on the grant date, the Company uses the Black-Scholes option valuation model. Award recipients are grouped according to expected exercise behavior. Unless better information is available to estimate the expected term of the options, the estimate is based on historical exercise experience. The risk-free rate, using U.S. Treasury yield curves in effect at the time of grant, is selected based on the expected term of each group. The Company’s historical stock price is used to estimate expected volatility. The fair value and inputs used to calculate fair value for options granted in the first six months of 2020 are included in the table below:

Fair value of options granted	$10.91
Exercise price	$58.91
Expected term (years)	4.75
Expected volatility	29.3%
Dividend yield	3.5%
Risk-free rate of return	1.6%

RSUs

Typically, the RSUs granted under the 2015 Plan and 2020 Plan vest after three years and one year of service, respectively. RSUs entitle the holders to one share of common stock for each vested RSU. Unvested RSUs do not have voting rights but are entitled to receive non-forfeitable dividends (generally after a performance hurdle has been satisfied for the year of the grant) or other distributions equal to those declared on the Company’s common stock for RSUs that are earned as a result of the satisfaction of the performance hurdle. The closing stock price on the grant date is used to determine the fair value of RSUs.

PSUs

The PSUs granted under the 2015 Plan are either total shareholder return PSUs (“TSR PSUs”) or return on invested capital PSUs (“ROIC PSUs”). The actual number of shares of the Company’s common stock that may be earned with respect to TSR PSUs is calculated by comparing the Company’s total shareholder return to the total shareholder return for each company comprising the Company’s peer group (for TSR PSUs granted in 2018 and later) over the three-year performance period and may range from 0% to 200% of the target number of shares based upon the attainment of these market conditions. The actual number of shares of common stock that may be earned with respect to ROIC PSUs is calculated based on the average of the Company’s annual return on invested capital for each year in the three-year performance period and may range from 0% to 200% of the target number of shares based upon the attainment of these performance conditions.

PSUs represent a target number of shares of the Company’s common stock that may be earned before adjustment based upon the attainment of certain conditions. Holders of PSUs do not have voting rights but are entitled to receive non-forfeitable dividends or other distributions equal to those declared on the Company’s common stock for PSUs that are earned, which are paid when the shares underlying the PSUs are paid.

To estimate the fair value of the TSR PSUs on the grant date, the Company uses a Monte-Carlo simulation model, which simulates future stock prices of the Company as well as the companies comprising the Russell 3000 Index or the Company’s peer group depending on the year granted. This model uses historical stock prices to estimate expected volatility and the Company’s correlation to the Russell 3000 Index or peer group. The risk-free rate was determined using the same methodology as the option valuations as discussed above. The Company’s closing stock price on the grant date was used to estimate the fair value of the ROIC PSUs. The Company will adjust the expense of the ROIC PSUs based upon its estimate of the number of shares that will ultimately vest at each interim date during the vesting period.

During the six months ended June 30, 2020, the Company reissued the following number of shares from treasury stock: no shares related to the exercise of stock options, 28,835 shares related to the release of RSUs which vested, 11,575 shares related to the release of PSUs which vested and 9,756 shares related to stock payments. In 2019, the Company issued 32,197 shares from treasury stock. The Company withheld 14,627 shares with a fair value of $0.7 million related to the vesting of RSUs and PSUs during the first six months of 2020. The fair value of the shares were valued at the closing price at the vesting date and represent the employee tax withholding for the employee’s compensation. The Company recognized a tax deficiency of $0.1 million from its equity compensation awards as an increase to income tax expense during the first six months of 2020. During the first six months of 2020 and 2019, the Company recorded $5.6 million (includes $0.5 million paid in cash) and $3.4 million, respectively, of compensation expense pursuant to its stock-based compensation plans. No amounts have been capitalized. The following table summarizes stock-based compensation activity during the six months ended June 30, 2020:

	Stock Options			RSUs			PSUs(a)
	Number	Weighted-average exercise price		Number	Weighted-average fair value		Number	Weighted-average fair value

Derivative Instruments and Hedging Activities Disclosure [Abstract]

Derivative Financial Instruments

Derivative Financial Instruments:

The Company is subject to various types of market risks, including interest rate risk, foreign currency exchange rate transaction and translation risk and commodity pricing risk. Management may take actions to mitigate the exposure to these types of risks, including entering into forward purchase contracts and other financial instruments. Currently, the Company manages a portion of its commodity pricing and foreign currency exchange rate risks by using derivative instruments. From time to time, the Company may enter into immaterial foreign exchange contracts to mitigate foreign exchange risk on its sales and accounts receivable. The Company does not seek to engage in trading activities or take speculative positions with any financial instrument arrangement. The Company has entered into natural gas derivative instruments and foreign currency derivative instruments with counterparties it views as creditworthy. However, the Company does attempt to mitigate its counterparty credit risk exposures by, among other things, entering into master netting agreements with some of these counterparties. The Company records derivative financial instruments as either assets or liabilities at fair value in the Consolidated Balance Sheets.

Derivatives qualify for treatment as hedges when there is a high correlation between the change in fair value of the derivative instrument and the related change in value of the underlying hedged item. Depending on the exposure being hedged, the Company must designate the hedging instrument as a fair value hedge, a cash flow hedge or a net investment in foreign operations hedge. For the qualifying derivative instruments that have been designated as hedges, the change in fair value is recognized through earnings when the underlying transaction being hedged affects earnings, allowing a derivative’s gains and losses to offset related results from the hedged item in the statements of operations. Any ineffectiveness related to these hedges was not material for any of the periods presented. For derivative instruments that have not been designated as hedges, the entire change in fair value is recorded through earnings in the period of change.

Natural Gas Derivative Instruments

Natural gas is consumed at several of the Company’s production facilities, and changes in natural gas prices impact the Company’s operating margin. The Company’s objective is to reduce the earnings and cash flow impacts of changes in market prices of natural gas by fixing the purchase price of up to 90% of its forecasted natural gas usage. It is the Company’s policy to consider hedging portions of its natural gas usage up to 36 months in advance of the forecasted purchase. As of June 30, 2020, the Company had entered into natural gas derivative instruments to hedge a portion of its natural gas purchase requirements through December 2021. As of June 30, 2020 and December 31, 2019, the Company had agreements in place to hedge forecasted natural gas purchases of 3.1 million and 2.8 million MMBtus, respectively. All natural gas derivative instruments held by the Company as of June 30, 2020 and December 31, 2019 qualified and were designated as cash flow hedges. As of June 30, 2020, the Company expects to reclassify from accumulated other comprehensive loss to earnings during the next twelve months $0.2 million of net losses on derivative instruments related to its natural gas hedges.

Foreign Currency Derivatives Not Designated as Hedges

In March 2020, the Company entered into forward instruments to swap currency denominated in U.S. dollars to Canadian dollars for a future intercompany payment from a U.S. subsidiary to a Canadian subsidiary. These instruments matured in April 2020 with combined notional amounts of $89.9 million. The objective of the instruments was to mitigate the foreign currency fluctuation risk related to intercompany payments denominated in a currency other than U.S. dollars, the Company’s functional currency. The instrument was not designated as a hedge. During the six months ended June 30, 2020, the Company recognized a foreign exchange loss of $3.1 million in its Consolidated Statements of Operations for these agreements.

Foreign Currency Derivatives Designated as Hedges

The Company has entered into U.S. dollar-denominated debt instruments to provide funds for its operations in Brazil. The Company may also concurrently enter into foreign currency agreements whereby the Company agrees to swap interest and principal payments on loans denominated in U.S. dollars for principal and interest payments denominated in Brazilian reais, its Brazil subsidiary’s functional currency. The objective of the swap agreements is to mitigate the foreign currency fluctuation risk related to holding debt denominated in a currency other than the Company’s Brazil subsidiary’s functional currency. As of June 30, 2020, the Company had a swap agreement in place to hedge $9.5 million of a loan denominated in a currency other than its Brazil subsidiary’s functional currency. Payments on this loan are due on various dates extending through February 2021. As of June 30, 2020, this foreign currency derivative instrument qualified and was designated as a cash flow hedge. As of June 30, 2020, the Company expects to reclassify from accumulated other comprehensive loss to earnings during the next twelve months $2.2 million of net gains on derivative instruments related to this foreign currency swap agreement.

The following tables present the fair value of the Company’s hedged items as of June 30, 2020 and December 31, 2019 (in millions):

Fair Value Disclosures [Abstract]

Fair Value Measurements

Fair Value Measurements:

The Company’s financial instruments are measured and reported at their estimated fair values. Fair value is the price that would be received upon the sale of an asset or paid to transfer a liability in an orderly transaction. When available, the Company uses quoted prices in active markets to determine the fair values for its financial instruments (Level 1 inputs) or, absent quoted market prices, observable market-corroborated inputs over the term of the financial instruments (Level 2 inputs). The Company does not have any unobservable inputs that are not corroborated by market inputs (Level 3 inputs).

The Company holds marketable securities associated with its defined contribution and pre-tax savings plans, which are valued based on readily available quoted market prices. The Company utilizes derivative instruments to manage its risk of changes in natural gas prices and its risk of changes in foreign currency exchange rates (see Note 12). The fair values of the natural gas and foreign currency derivative instruments are determined using market data of forward prices for all of the Company’s contracts. 

The estimated fair values for each type of instrument are presented below (in millions):

	June 30, 2020		Level One		Level Two		Level Three

Cash and cash equivalents, receivables (net of allowance for doubtful accounts) and payables are carried at cost, which approximates fair value due to their liquid and short-term nature. The Company’s investments related to its nonqualified savings plan of $1.6 million and $1.4 million at June 30, 2020 and December 31, 2019, respectively, are stated at fair value based on quoted market prices. As of June 30, 2020 and December 31, 2019, the estimated amount a third party would pay for the Company’s fixed-rate 4.875% Senior Notes due July 2024, based on available trading information (Level 2), totaled $252.5 million and $249.1 million, respectively, compared with the aggregate principal amount at maturity of $250.0 million. As of June 30, 2020 and December 31, 2019, the estimated amount a third party would pay for the Company’s fixed-rate 6.75% Senior Notes due December 2027, based on available trading information (Level 2), totaled $530.0 million and $530.6 million, respectively, compared with the aggregate principal amount at maturity of $500.0 million. The estimated amount a third party would pay at June 30, 2020 and December 31, 2019 for the amounts outstanding under the Company’s term loans and revolving credit facility, based upon available bid information received from the Company’s lender (Level 2), totaled $448.9 million and $552.8 million, respectively, compared with the aggregate principal balance of $454.0 million and $560.0 million, respectively. The Brazilian loans have floating rates and their fair value approximates their carrying value.

Receivables [Abstract]

Securitization

Securitization:

On June 30, 2020, certain of the Company’s U.S. subsidiaries entered into a three-year committed revolving accounts receivable financing facility (the “AR Facility”) of up to $100 million with PNC Bank, National Association (“PNC”), as administrative agent and lender, and PNC Capital Markets, LLC, as structuring agent.

In connection with the AR Facility, two of the Company’s U.S. subsidiaries will, from time to time sell and contribute accounts receivable and certain related assets to a special purposes entity and wholly-owned U.S. subsidiary of the Company (the “SPE”). The SPE will finance its acquisition of the receivables by obtaining secured loans from PNC and the other lenders party to a receivables financing agreement. A U.S. subsidiary of the Company will service the accounts receivables on behalf of the SPE for a fee. In addition, the Company has agreed to guarantee the performance by its subsidiaries. The Company and its subsidiaries do not guarantee the loan principal or interest under the receivables financing agreement or the collectability of the receivables under the AR Facility. In July 2020, the Company received proceeds from its first loan amount of $24.0 million.

The purchase price for the sale of receivables will consist of cash available to the SPE from loans under the AR Facility and from collections on previously sold receivables and, to the extent the SPE does not have funds available to pay the purchase price due on any day in cash, through an increase in the principal amount of a subordinated intercompany loan. The SPE will pay monthly interest and fees with respect to amounts advanced by the lenders under the AR Facility.

The SPE’s sole business consists of the purchase or acceptance through capital contributions of the receivables and the subsequent granting of a security interest in these receivables and related rights to PNC on behalf of the lenders under the AR Facility. The SPE is a separate legal entity with its own separate creditors who will be entitled, upon its liquidation, to be satisfied out of the SPE’s assets prior to any assets or value in the SPE becoming available to the Company and the assets of the SPE are not available to pay creditors of the Company or any of its affiliates other than the SPE.

Accounting Policies [Abstract]

Basis of Consolidation

CMI is a holding company with no significant operations other than those of its wholly-owned subsidiaries. The consolidated financial statements include the accounts of CMI and its wholly-owned subsidiaries. All significant intercompany balances and transactions have been eliminated in consolidation.

Equity Method Investments

The Company uses the equity method of accounting for equity securities when it has significant influence or when it has more than a minor ownership interest or more than minor influence over an investee’s operations but does not have a controlling financial interest. Initial investments are recorded at cost (including certain transaction costs) and are adjusted by the Company’s share of the investees’ undistributed earnings and losses.

Basis of Presentation

The accompanying unaudited consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”) for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by U.S. GAAP for complete financial statements. These unaudited consolidated financial statements should be read in conjunction with the consolidated financial statements of the Company for the year ended December 31, 2019, as filed with the Securities and Exchange Commission (“SEC”) in its Annual Report on Form 10-K. In the opinion of management, all adjustments, consisting of normal recurring adjustments considered necessary for a fair presentation, have been included.

Significant and Recent Accounting Pronouncements

Significant Accounting Policies

The Company’s significant accounting policies are detailed in “Note 2 – Summary of Significant Accounting Policies” within Item 8 of the Company’s Annual Report on Form 10-K for the year ended December 31, 2019.

Recent Accounting Pronouncements

In January 2017, the Financial Accounting Standards Board (“FASB”) issued guidance to simplify the accounting for goodwill impairment. The guidance removes Step 2 of the goodwill impairment test, which requires a hypothetical purchase price

allocation. A goodwill impairment will now be the amount by which a reporting unit’s carrying value exceeds its fair value, not to exceed the carrying amount of goodwill. All other goodwill impairment guidance remains largely unchanged. The adoption of this guidance on January 1, 2020 did not have an impact on the Company’s consolidated financial statements.

On January 1, 2020, the Company adopted guidance issued by the FASB related to credit losses for financial instruments, which replaces the incurred loss methodology with a current expected credit loss methodology (“CECL”). The Company has determined that its trade receivables are the only financial instrument that is within scope of this CECL guidance. The CECL methodology requires financial assets to be recorded at the net amount expected to be collected over the lifetime of the asset such that the estimated losses are accrued on the day the asset is acquired. The CECL methodology also requires financial assets to be aggregated and evaluated within pools with similar risk characteristics.

The Company has recorded an allowance on its trade receivables based on historical loss rates modified to consider supportable forecasts related to customer-specific and macroeconomic factors. For instance, the Company’s 2020 allowance for doubtful accounts considered the potential impact that the coronavirus pandemic could have on the collectability of its outstanding receivables. The Company’s customer pools are comprised of North American highway deicing customers, North American consumer and industrial customers, Plant Nutrition North America customers, Plant Nutrition South America customers and customers whose outstanding receivable balances have been sent to collections. Customers grouped within these pools have similar risk characteristics. The Company’s allowance for doubtful accounts consists of estimates of expected credit losses and accruals for returns and allowances. At the transition date of January 1, 2020, the implementation of CECL had an immaterial impact of less than $0.1 million on the Company’s consolidated financial statements. Under CECL, the Company had an allowance for doubtful accounts of $9.4 million and $8.2 million as of January 1, 2020, and June 30, 2020, respectively.

Derivative Financial Instruments

The Company is subject to various types of market risks, including interest rate risk, foreign currency exchange rate transaction and translation risk and commodity pricing risk. Management may take actions to mitigate the exposure to these types of risks, including entering into forward purchase contracts and other financial instruments. Currently, the Company manages a portion of its commodity pricing and foreign currency exchange rate risks by using derivative instruments. From time to time, the Company may enter into immaterial foreign exchange contracts to mitigate foreign exchange risk on its sales and accounts receivable. The Company does not seek to engage in trading activities or take speculative positions with any financial instrument arrangement. The Company has entered into natural gas derivative instruments and foreign currency derivative instruments with counterparties it views as creditworthy. However, the Company does attempt to mitigate its counterparty credit risk exposures by, among other things, entering into master netting agreements with some of these counterparties. The Company records derivative financial instruments as either assets or liabilities at fair value in the Consolidated Balance Sheets.

Derivatives qualify for treatment as hedges when there is a high correlation between the change in fair value of the derivative instrument and the related change in value of the underlying hedged item. Depending on the exposure being hedged, the Company must designate the hedging instrument as a fair value hedge, a cash flow hedge or a net investment in foreign operations hedge. For the qualifying derivative instruments that have been designated as hedges, the change in fair value is recognized through earnings when the underlying transaction being hedged affects earnings, allowing a derivative’s gains and losses to offset related results from the hedged item in the statements of operations. Any ineffectiveness related to these hedges was not material for any of the periods presented. For derivative instruments that have not been designated as hedges, the entire change in fair value is recorded through earnings in the period of change.
