NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

1. Accounting Policies and Basis of Presentation:

Compass Minerals International, Inc., through its subsidiaries, is a producer and marketer of essential mineral products with manufacturing sites in North America and the United Kingdom (“U.K.”). References to the “Company,” “Compass,” “Compass Minerals,” “CMP,” “we,” “us” and “our” refer to Compass Minerals International, Inc. (“CMI”, the parent holding company) and its consolidated subsidiaries. The Company’s principal products are salt, consisting of sodium chloride and magnesium chloride, and sulfate of potash (“SOP”), a specialty fertilizer the Company markets under the trade name Protassium+™.  Additionally, the Company sells various premium micronutrient products under its Wolf Trax® brand.  The Company provides highway deicing products to customers in North America and the U.K., and plant nutrients to growers and fertilizer distributors worldwide.  The Company also produces and markets consumer deicing and water conditioning products, ingredients used in consumer and commercial food preparation, and other mineral-based products for consumer, agricultural and industrial applications.  Compass Minerals also provides records management services to businesses located in the U.K.

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

The accompanying unaudited consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles 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. generally accepted accounting principles (“GAAP”) for complete financial statements. These unaudited consolidated financial statements should be read in conjunction with the consolidated financial statements of CMP for the year ended December 31, 2014 as filed with the Securities and Exchange Commission in its Annual Report on Form 10-K. In the opinion of management, all adjustments, consisting of normal recurring accruals considered necessary for a fair presentation, have been included.

The Company experiences a substantial amount of seasonality in salt segment sales, primarily with respect to its deicing products. As a result, 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 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 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.

Recent Accounting Pronouncements – In April 2015, the Financial Accounting Standards Board (“FASB”) issued guidance which requires debt issuance costs to be presented in the balance sheet as a direct deduction from the related debt liability rather than an asset.  The recognition and measurement guidance for debt issuance costs are not affected by this guidance.  This new guidance is effective retrospectively for fiscal years, and interim periods within those years, beginning after December 15, 2015.  Early adoption is permitted.  The Company does not expect that this guidance will have a material impact on its consolidated financial statements.

In August 2014, the FASB issued guidance which requires management to evaluate whether there is substantial doubt about an entity’s ability to continue as a going concern and to provide disclosure in the footnotes under certain circumstances.  This guidance is effective for fiscal years ending after December 15, 2016 with early adoption permitted.  The Company does not expect that this guidance will have a material impact on its consolidated financial statements.

In May 2014, the FASB issued guidance to provide a single, comprehensive revenue recognition model for all contracts with customers.  The new revenue recognition model supersedes existing revenue recognition guidance and requires revenue recognition to depict the transfer of promised goods or services to customers in an amount that reflects the consideration an entity expects to receive in exchange for those goods or services.  This guidance is effective for fiscal years and interim periods with those years beginning after December 15, 2016 and early adoption is not permitted.  The guidance permits the use of either a full or modified retrospective or cumulative effect transition method.  The Company is currently evaluating the impact that the implementation of this standard will have on its consolidated financial statements.

4. Goodwill and Intangible Assets, Net:

The asset value and accumulated amortization as of March 31, 2015 and December 31, 2014 for the finite-lived intangibles assets are as follows (in millions):

	Supply Agreement			SOP Production Rights			Customer/ Distributor Relationships			Lease Rights			Patents			Other			Total
March 31, 2015:
Gross intangible asset	$	28.6		$	24.3		$	7.4		$	1.8		$	16.3		$	4.3		$	82.7

Net finite-lived intangible assets	$	28.8		$	13.5		$	6.1		$	1.7		$	16.7		$	4.0		$	70.8

8

The estimated lives of the Company’s intangible assets are as follows:

Intangible asset	Estimated Lives
Supply agreement		50 years
SOP production rights		25 years
Patents		10-20 years
Developed technology		5 years
Lease rights		25 years
Customer and distributor relationships		5-10 years
Trademarks		10 years
Noncompete agreements		5 years
Trade names		Indefinite
Water rights		Indefinite

None of the finite-lived intangible assets have a residual value.  Aggregate amortization expense was $1.1 million and $0.5 million in the first quarter of 2015 and 2014, respectively.

In addition, the Company has water rights of $22.9 million as of March 31, 2015 and December 31, 2014, and trade names of $11.3 million and $12.4 million as of March 31, 2015 and December 31, 2014, respectively.

The Company has goodwill of $63.1 million and $68.5 million as of March 31, 2015 and December 31, 2014, in its consolidated balance sheets.  Approximately $56.7 million and $62.0 million of the amounts recorded for goodwill as of March 31, 2015 and December 31, 2014, respectively, were recorded in the Company’s plant nutrition segment and the remaining amounts in both periods were immaterial and recorded in its corporate and other and salt segment.  The change in goodwill from December 31, 2014 was due to the impact from translating foreign denominated amounts to U.S. dollars.

5. 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 tax rate differentials, foreign mining taxes, domestic manufacturing deductions, and interest expense recognition differences for book and tax purposes.  The Company’s effective rate is impacted by permanent tax deductions which have a less favorable impact as pretax income increases.

At both March 31, 2015 and December 31, 2014, the Company had approximately $3.8 million of gross foreign federal net operating loss (“NOL”) carryforwards that have no expiration date.  In addition, as of December 31, 2014, the Company had $2.3 million of gross federal NOL carryforwards which expire in 2033 and $0.3 million of tax-effected state NOL carryforwards which expire in 2033. In the future, if the Company determines, based on the existence of sufficient evidence, that it should realize more or less of its deferred tax assets, an adjustment to any existing valuation allowance will be made in the period such determination is made.

Canadian provincial tax authorities have challenged tax positions claimed by one of the Company’s Canadian subsidiaries and have issued tax reassessments for years 2002-2009.  The reassessments are a result of ongoing audits and total approximately $83 million, including interest through March 31, 2015.  The Company disputes these reassessments and plans to 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 and the tax authority have agreed that it will post collateral in the form of a $44 million performance bond.  The Company has paid approximately $30 million (most of which is recorded in other assets in the consolidated balance sheets) with the remaining balance to be paid after 2015.  The Company will be required by the same local regulations to provide security for additional interest on the above 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 dispute is resolved.

In addition, Canadian federal and provincial taxing authorities have reassessed the Company for years 2004-2006 which have been previously settled by agreement among the Company, the Canadian federal taxing authority and the U.S. federal taxing authority.  The Company has fully complied with the agreement since entering into it and it believes this action is highly unusual.  The Company is seeking to enforce the agreement which provided the basis upon which the returns were previously filed and settled.  The total amount of the reassessments, including penalties and interest through March 31, 2015, related to this matter is approximately $92 million.  The Company has agreed to post collateral in the form of an approximately $19 million performance bond and $40 million in the form of a bank letter guarantee which is necessary to proceed with future appeals or litigation.

9

As of March 31, 2015, the Company received Canadian income tax reassessments for years 2007-2008.  The total amount of the reassessments, including penalties and interest through March 31, 2015, related to this matter is approximately $31 million.  The Company does not agree with these adjustments and plans to apply for assistance under Competent Authority provided in the tax treaty between the U.S. and Canadian taxing authorities for relief from the impact of any double taxation.  The Company will file protective Notices of Objection and will post collateral when required by tax authorities.  Although the outcome of examinations by taxing authorities is uncertain, the Company believes it has adequately reserved for this matter.

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 March 31, 2015, the amount reserved related to these reassessments was immaterial to the Company’s consolidated financial statements.

Additionally, the Company has other uncertain tax positions as well as assessments and disputed positions with taxing authorities in its various jurisdictions.

6. Long-term Debt:

Long-term debt consists of the following (in millions):

	March 31, 2015			December 31, 2014
Term Loan due May 2017	$	375.4		$	376.4
Revolving Credit Facility due August 2017		-			-
4.875% Senior Notes due July 2024		250.0			250.0
		625.4			626.4
Less current portion		(3.9	)		(3.9	)
Long-term debt	$	621.5		$	622.5

The term loan and revolving credit facility are secured by substantially all existing and future assets of the Company’s subsidiaries.

7. Commitments and Contingencies:

The Company is involved in legal and administrative proceedings and claims of various types from normal Company activities.

The Company is aware of an aboriginal land claim filed in 2003 by The Chippewas of Nawash and The Chippewas of Saugeen (the “Chippewas”) in the Ontario Superior Court against The Attorney General of Canada and Her Majesty The Queen In Right of Ontario. The Chippewas claim that a large part of the land under Lake Huron was never surrendered by treaty and thus seek a declaration that the Chippewas hold aboriginal title to those submerged lands.  The land to which aboriginal title is claimed includes land under which the Company’s Goderich mine operates and has mining rights granted to it by the government of Ontario. The actions also seek damages for the value and loss of use of lands.  The Company is not a party to the court actions. The Company understands that Canada and Ontario are defending the actions for aboriginal title on the basis, among other things, that common law does not recognize aboriginal title to the Great Lakes and other navigable waterways.

Similar claims are pending with respect to other parts of the Great Lakes by other aboriginal claimants. The Company has been informed by the Ministry of The Attorney General of Ontario that “Canada takes the position that the common law does not recognize aboriginal title to the Great Lakes and its connecting waterways.”

The Company is involved in proceedings alleging unfair labor practices at its Cote Blanche, Louisiana, mine.  This matter arises out of a labor dispute between the Company and the United Steelworkers Union over the terms of a new contract for certain employees at the mine. These employees initiated a strike that began on April 7, 2010, and ended on June 15, 2010.  In September 2012, the U.S. National Labor Relations Board (“NLRB”) issued a decision finding that the Company had committed unfair labor practices in connection with the labor dispute.  Under the ruling, the Company is responsible for back pay to affected employees as a result of changes made in union work rules and past practices beginning April 1, 2010.  Any requirement for the Company to pay back wages will be offset by any wages earned at other places of employment during this period.  In the fourth quarter of 2013, this ruling was upheld by an appeals court and the Company recorded a reserve of approximately $5 million in its consolidated financial statements related to expected payments required to resolve the dispute.

In the first quarter of 2015, additional information became available and the Company recorded an additional $2 million reserve for this matter in its consolidated financial statements.  Both parties are currently negotiating in an effort to reach a settlement. If the Company is unable to come to terms with the union, the parties may agree to arbitration and any decisions

10

reached in arbitration would be binding.  The Company may need to record additional losses in its financial statements as a result of future developments.

The Wisconsin Department of Agriculture, Trade and Consumer Protection (“DATCP”) has information indicating that agricultural chemicals are present within the subsurface area of the Kenosha, Wisconsin plant. The agricultural chemicals were used by previous owners and operators of the site.  None of the identified chemicals have been used in association with Compass Minerals’ operations since it acquired the property in 2002.  DATCP directed the Company to conduct further investigations into the possible presence of agricultural chemicals in soil and ground water at the Kenosha plant.  The Company has completed such investigations of the soils and ground water and has provided the findings to DATCP. The Company is presently proceeding with select remediation activities to mitigate agricultural chemical impact to soils and ground water at the site.  All investigations and mitigation activities to date, and any potential future remediation work, are being conducted under the Wisconsin Agricultural Chemical Cleanup Program (“ACCP”), which would provide for reimbursement of some of the costs. The Company may seek participation by, or cost reimbursement from, other parties responsible for the presence of any agricultural chemicals found in soil and ground water at this site if the Company does not receive an acknowledgement of no further action and is required to conduct further investigation or remedial work that may not be eligible for reimbursement under the ACCP.

In December 2009, a surface salt storage dome which was under construction collapsed at the Company’s mine in Goderich, Ontario. The Company was involved in construction litigation and other contract claims with the contractor and engineering firm relating to the dome’s collapse.  Claims asserted against the Company totaled approximately $13 million.  The Company also counterclaimed for damages and withheld payment for some invoices. In the first quarter of 2015, the parties have agreed to settle this matter for a $4.2 million cash payment by the Company, most of which was for the payment of invoices.  As a result, the Company has recognized a gain of approximately $0.7 million in its consolidated financial statements.

The Company is also involved in legal and administrative proceedings and claims of various types from normal Company activities.

The Company does not believe that these actions will have a material adverse financial effect on the Company. Furthermore, while any litigation contains an element of uncertainty, management presently believes that the outcome of each such proceeding or claim, which is pending or known to be threatened, or all of them combined, will not have a material adverse effect on the Company’s results of operations, cash flows or financial position.

The Company broadened its portfolio of specialty plant nutrient products with the acquisition of Wolf Trax, Inc. (renamed Compass Minerals Manitoba, Inc. or “Compass Manitoba”) in the second quarter of 2014.  This acquisition broadens the Company’s portfolio of specialty crop nutrient products and further differentiates it from commodity fertilizers.  The results of operations and financial position for Compass Manitoba have been included in the Company’s plant nutrition segment from the date of the acquisition.  Segment information is as follows (in millions):

(a) Corporate and Other includes corporate entities, records management operations and other incidental operations and eliminations.  Operating earnings (loss) for corporate and other includes indirect corporate overhead including costs for general corporate governance and oversight, as well as costs for the human resources, information technology and finance functions.

9. Stockholders’ Equity and Equity Instruments:

In the first quarter of 2015, the Company granted 119,769 stock options, 19,311 restricted stock units (“RSUs”) and 35,251 performance stock units (“PSUs”) to certain employees under its 2005 Incentive Award Plan.  The Company’s closing stock price on the grant date was used to set the exercise price for the options and the fair value of the RSUs.  The options vest ratably on each anniversary date over a four-year service period. Unexercised options expire after seven years. The RSUs vest on the third anniversary following the grant date. None of the awards granted have voting rights.  The RSUs granted entitle the holders to receive non-forfeitable dividends or other distributions equal to those declared on the Company’s common stock for RSUs earned.

The PSUs granted in the first quarter of 2015 have a three-year performance period beginning in 2015 and ending in 2017 and earn between 0% and 150% based upon the attainment of certain performance conditions.  The Company granted two types of PSUs in the first quarter of 2015.  The total shareholder return PSU (“TSR PSU”) is earned by determining the Company’s total shareholder return, compared to the total shareholder return for each company comprising the Russell 3000 Index over the three-year performance period.  The return on invested capital PSU (“ROIC PSU”) is earned by averaging the Company’s annual return on invested capital over the three-year performance period.  The performance units will vest three years after the grant date.  The PSUs granted entitle the holders to receive non-forfeitable dividends or other distributions equal to those declared on the Company’s common stock from the grant date through the vest date for PSUs earned.

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 range of estimates and calculated fair values for options granted during the first quarter of 2015 is included in the table below. The weighted-average grant date fair value of these options was $14.79.

	Range
Fair value of options granted		$14.34 - $15.09
Exercise price		$91.75
Expected term (years)		4.5-5
Expected volatility		24.8% - 25.0%
Dividend yield		3.1%
Risk-free rate of return		1.5% - 1.6%

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.  This model uses historical stock prices to estimate expected volatility and the Company’s correlation to the Russell 3000 Index.  The risk-free rate was determined using the same methodology as the option valuations as discussed above. The estimated fair value of the TSR PSUs granted in 2015 is $111.07 per unit.  The Company’s closing stock price on the grant date was used to set 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 three-year vesting period.

During the three months ended March 31, 2015, the Company reissued 28,903 shares of treasury stock related to the exercise of stock options, 15,952 shares related to the release of RSUs which vested, 10,454 shares related to the release of PSUs

12

which vested and 245 shares related to stock payments.  The Company recognized a tax benefit of $0.1 million from its equity compensation awards as an increase to additional paid-in capital during the first quarter of 2015. During the first quarters of 2015 and 2014, the Company recorded $1.6 million and $1.2 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 three months ended March 31, 2015.

	Stock Options					RSUs					PSUs(a)
	Number			Weighted-average exercise price		Number			Weighted-average fair value		Number			Weighted-average fair value
Outstanding at December 31, 2014		278,429		$	79.23		88,532		$	76.58		59,627		$	88.69

(a) Until they vest, PSUs are included in the table at the 100% attainment level at their grant date and at that level represent one share per unit.  The final performance period for the 2012 PSU grant was completed in 2014.  The Company issued 10,454 shares and cancelled 4,443 PSUs due to performance in the first quarter of 2015 related to the 2012 PSU grant.

(b) Common stock issued for exercised options and RSUs and PSUs released from restriction were issued from treasury stock.

Other Comprehensive Income (Loss)

The Company’s comprehensive income (loss) is comprised of net earnings, net amortization of the unrealized loss of the pension obligation, the change in the unrealized gain (loss) on natural gas cash flow hedges and foreign currency translation adjustments.  The components of and changes in accumulated other comprehensive income (“AOCI”) as of and for the three months ended March 31, 2015 and 2014 are as follows (in millions):

Three Months Ended March 31, 2015 (a)	Gains and (Losses) on Cash Flow Hedges			Defined Benefit Pension			Foreign Currency			Total
Beginning balance	$	(2.0	)	$	(9.0	)	$	(4.5	)	$	(15.5	)

10. 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 risk by using derivative instruments.  The Company does not seek to engage in trading activities or take speculative positions with any financial instrument arrangements. The Company has entered into natural gas derivative instruments with counterparties it views as creditworthy.  However, management does attempt to mitigate its counterparty credit risk exposures by, among other things, entering into master netting agreements with these counterparties.

Cash Flow Hedges

As of March 31, 2015, the Company has entered into natural gas derivative instruments. The Company records derivative financial instruments as either assets or liabilities at fair value in the consolidated statements of financial position.  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.  All derivative instruments held by the Company as of March 31, 2015 and December 31, 2014 qualified as cash flow hedges. For these qualifying hedges, the effective portion of 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 (see Note 9). For derivative instruments that are not accounted for as hedges, or for the ineffective portions of qualifying hedges, the change in fair value is recorded through earnings in the period of change. The Company formally documents, designates, and assesses the effectiveness of transactions that receive hedge accounting treatment initially and on an ongoing basis.  Any ineffectiveness related to these hedges was not material for any of the periods presented.

Natural gas is consumed at several of the Company’s production facilities, and a change in natural gas prices impacts the Company’s operating margin.  As of March 31, 2015, the Company had entered into natural gas derivative instruments to hedge a portion of its natural gas purchase requirements through December 2016.  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 March 31, 2015 and December 31, 2014, the Company had agreements in place to hedge forecasted natural gas purchases of 2.6 million and 3.4 million MMBtus, respectively.

As of March 31, 2015, the Company expects to reclassify from accumulated other comprehensive income to earnings during the next twelve months approximately $2.3 million of net losses on derivative instruments related to its natural gas hedges.

14

The following tables present the fair value of the Company’s hedged items as of March 31, 2015 and December 31, 2014, (in millions):

	Asset Derivatives			Liability Derivatives
Derivatives designated as hedging instruments(a) (b)	Balance Sheet Location	March 31, 2015		Balance Sheet Location	March 31, 2015
Commodity contracts	Other current assets	$	-	Accrued expenses	$	2.1
Commodity contracts	Other assets		-	Other noncurrent liabilities		1.2
Total derivatives designated as hedging instruments		$	-		$	3.3

(a) As of March 31, 2015, the Company has commodity hedge agreements with four counterparties.  All of the counterparties are in payable positions.

(b) The Company has master netting agreements with its counterparties and accordingly has netted in its consolidated balance sheets immaterial amounts that are in receivable and payable positions with larger amounts that are in payable and receivable positions, respectively.

	Asset Derivatives			Liability Derivatives
Derivatives designated as hedging instruments(a) (b)	Balance Sheet Location	December 31, 2014		Balance Sheet Location	December 31, 2014
Commodity contracts	Other current assets	$	0.1	Accrued expenses	$	2.5
Commodity contracts	Other assets		-	Other noncurrent liabilities		1.0
Total derivatives designated as hedging instruments		$	0.1		$	3.5

(a) The Company has commodity hedge agreements with four counterparties.  Amounts recorded as liabilities for the Company’s commodity contracts are payable to all counterparties.  The amount recorded as an asset is due from two counterparties.

(b) The Company has master netting agreements with its counterparties and accordingly has netted in its consolidated balance sheets approximately $0.1 million of its commodity contracts that are in a receivable position against its contracts in payable positions.

11. Fair Value Measurements:

The Company’s financial instruments are measured and reported at their estimated fair value.  Fair value is the price that would be received to sell 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 one inputs), or absent quoted market prices, observable market-corroborated inputs over the term of the financial instruments (level two inputs). The Company does not have any unobservable inputs that are not corroborated by market inputs (level three inputs).

15

The Company holds marketable securities associated with its non-qualified retirement plan, 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.  The fair value of the natural gas 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).

	March 31, 2015			Level One			Level Two			Level Three
Asset Class:
Mutual fund investments in a non-qualified retirement plan(a)	$	1.8		$	1.8		$	-		$	-
Total Assets	$	1.8		$	1.8		$	-		$	-
Liability Class:
Liabilities related to non-qualified retirement plan	$	(1.8	)	$	(1.8	)	$	-		$	-
Derivatives – natural gas instruments		(3.3	)		-			(3.3	)		-
Total Liabilities	$	(5.1	)	$	(1.8	)	$	(3.3	)	$	-

(a) Includes mutual fund investments of approximately 15% in the common stock of large-cap U.S. companies, approximately 5% in the common stock of small-cap U.S. companies, approximately 5% in international companies, approximately 5% in bond funds, approximately 30% in short-term investments and approximately 40% in blended funds.

	December 31, 2014			Level One			Level Two			Level Three
Asset Class:
Mutual fund investments in a non-qualified savings plan(a)	$	1.9		$	1.9		$	-		$	-
Total Assets	$	1.9		$	1.9		$	-		$	-
Liability Class:
Liabilities related to non-qualified savings plan	$	(1.9	)	$	(1.9	)	$	-		$	-
Derivatives – natural gas instruments		(3.4	)		-			(3.4	)		-
Total Liabilities	$	(5.3	)	$	(1.9	)	$	(3.4	)	$	-

(a) Includes mutual fund investments of approximately 15% in the common stock of large-cap U.S. companies, approximately 5% in the common stock of international companies, approximately 5% in bond funds, approximately 35% in short-term investments and approximately 40% in blended funds.

Cash and cash equivalents, accounts receivable (net of allowance for bad debts) 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 retirement plan of $1.8 million and $1.9 million as of March 31, 2015 and December 31, 2014, respectively, are stated at fair value based on quoted market prices.  As of March 31, 2015, the estimated amount a third-party would pay for the fixed-rate 4.875% senior notes, based on available trading information, totaled $250.6 million (level 2) compared with the aggregate principal amount at maturity of $250.0 million. The estimated amount a third-party would pay at March 31, 2015 for the amounts outstanding under the credit agreement, based upon available bid information received from the Company’s lender, totaled $371.6 million (level 2) compared with the aggregate principal balance of $375.4 million.

12. 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 March 31,
	2015			2014
Numerator:
Net earnings	$	60.6		$	50.2
Less: net earnings allocated to participating securities (a)		(0.3	)		(0.4	)
Net earnings available to common shareholders	$	60.3		$	49.8
Denominator (in thousands):
Weighted-average common shares outstanding, shares for basic earnings per share		33,626			33,502
Weighted-average awards outstanding (b)		23			18
Shares for diluted earnings per share		33,649			33,520
Net earnings per common share, basic	$	1.79		$	1.49
Net earnings per common share, diluted	$	1.79		$	1.49

(a) Participating securities include options, PSUs and RSUs that receive non-forfeitable dividends. Net earnings were allocated to participating securities of 216,000 and 220,000 for the three months ended March 31, 2015 and 2014, respectively.

(b) For the calculation of diluted 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 343,000 and 373,000 weighted-awards outstanding for the three months ended March 31, 2015 and 2014, respectively, which were anti-dilutive and therefore not included in the diluted earnings per-share calculation.

Critical Accounting Estimates

Preparation of our consolidated financial statements in accordance with generally accepted accounting principles 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, 2014, describe the significant accounting estimates and policies used in preparation of our consolidated financial statements. Actual results in these areas could differ from management’s estimates.

Results of Operations

Salt Segment

Salt is indispensable and enormously versatile with thousands of reported uses. In addition, there are no known cost-effective alternatives for most high-volume uses. As a result, our cash flows from salt have not been materially impacted through a variety of economic cycles. We are among the lowest-cost salt producers in our markets due to our high-grade quality salt deposits which are among the most extensive in the world, and through the use of effective mining techniques and efficient production processes.  Since the highway deicing business accounts for nearly half of our annual sales, our business is seasonal, therefore results and cash flows will vary depending on the severity of the winter weather in our markets.

Deicing products, consisting of deicing salt and magnesium chloride used by highway deicing and consumer and industrial customers, constitute a significant portion of our salt segment sales.  Our deicing sales are seasonal and can fluctuate from year to year depending on the severity of the winter season weather in the markets we serve.  Inventory management practices are employed to respond to the varying level of sales demand which impacts our production volumes, the resulting

18

per-ton cost of inventory and ultimately profit margins, particularly during the second and third quarters when we build our inventory levels for the upcoming winter.  Net earnings are typically lower during the second and third quarters than in the first and fourth quarters.

We assess the severity of winter weather compared to recent averages, using official government snow data and comparisons of our sales volumes to historical trends and other relevant data. Weather affects our highway and consumer and industrial deicing salt sales volumes and resulting gross profit. We estimate that the effect of winter weather in the markets we serve was below average in the first quarter of 2015 and above average in the first quarter of 2014.  Due to the severe 2013-2014 winter season, we purchased salt to supplement our production which unfavorably impacted our production costs. In addition, unplanned downtime at our North American mines in the first quarter of 2015 unfavorably impacted our production costs. The more severe winter in the first quarter of 2014 favorably impacted our sales and our operating earnings and depleted inventories in the market compared to the first quarter of 2015.  The depleted inventories in 2014 strained the adequate supply for deicing products and resulted in higher contract highway deicing prices during the 2014-2015 winter season.

Plant Nutrition Segment

Our plant nutrition segment includes sales of specialty plant nutrition products including SOP as well as micronutrient and other products under our Wolf Trax® product line.  SOP, a specialty potassium fertilizer product which is also an ingredient in specialty fertilizer blends, is used as a potassium source for high-value or chloride-sensitive crops and turf.  The yields and/or quality of many high-value or chloride-sensitive crops are generally better when SOP is used as a potassium nutrient rather than potassium chloride (“MOP” or “KCl”).  Our SOP product is marketed under the brand name Protassium+™.  Our Wolf Trax® product line is produced using proprietary and patented technologies.

The fertilizer market is influenced by many factors such as world grain and food supply, changes in consumer diets, general levels of economic activity, governmental food programs, and governmental agriculture and energy policies around the world.  Economic factors may impact the amount or type of crop grown in certain locations, or the type or amount of fertilizer product used.  Over the last decade, worldwide consumption of potash and other crop nutrients has increased in response to growing populations and the need for additional food supplies.  We expect the long-term demand for potassium and other plant nutrients to continue to grow as arable land per capita decreases, thereby requiring crop yield efficiencies.

Our domestic sales of Protassium+™ are concentrated in the Western and Southeastern U.S. where the crops and soil conditions favor the use of low-chloride potassium nutrients, such as SOP.  Consequently, weather patterns and field conditions in these locations can impact the amount of plant nutrient sales volumes.  Additionally, the demand for and market price of Protassium+™ may be affected by the broader potash market and the economics of the specialty crops SOP serves.

Our SOP production facility in Ogden, Utah, the largest in North America and one of only three large-scale SOP solar brine evaporation operations in the world, utilizes naturally occurring brines in its production process.  The brine moves through a series of solar evaporation ponds over a two to three-year production cycle. Since our production process relies on solar evaporation during the summer to produce SOP at our Ogden facility, the intensity of heat and wind speeds, and relative dryness of the weather conditions during that time impacts the amount of solar evaporation which occurs and correspondingly, the amount of mineral feedstock available to convert into finished product.  We expect the solar pond-based effective capacity to be up to 320,000 tons annually for the Ogden facility, when weather conditions at our site are typical. We are focusing our sales efforts domestically in markets which typically yield higher average selling prices, net of shipping and handling costs, due to their proximity to our facilities.

Our SOP production in Saskatchewan, Canada contributes 40,000 tons to our SOP capacity.  We combine sulfate-rich brine with sourced KCl to create SOP through ion exchange and glaserite processes at this facility.  We purchase the KCl under a long-term supply agreement.  This product is high-purity and in addition to crop nutrient applications is often used in specialty, non-agricultural applications.

In April 2014, we completed the acquisition of Wolf Trax, Inc., a privately-held Canadian corporation (recently renamed Compass Minerals Manitoba Inc. (“Compass Manitoba”)) for $95.5 million Canadian dollars (approximately $86.5 million U.S. dollars at the closing date) in cash after customary post-closing adjustments. The acquisition enhanced our position as a key resource for premium plant nutrition products by adding innovative crop nutrient products based upon proprietary and patented technologies.

Beginning in the latter half of 2013, we purchased and consumed KCl feedstock at our Ogden facility to supplement the potassium available for our SOP harvest, and we increased the volume of KCl feedstock in 2014.  These KCl feedstock purchases helped increase production volumes, yet resulted in increased per-unit costs.  In addition, we experienced heavy localized rainfall during the summer of 2014 which limited our deposit of raw materials and will result in a continuation of the purchases of KCl and/or potassium feedstock in 2015 and at higher levels than in 2014. As the spread between market prices for SOP and KCl has increased, the economics of producing SOP partly from KCl has improved for our unique KCl conversion process.  While these KCl purchases will increase our expected full year product cost and reduce the resulting margin percentages, they are also expected to increase our gross profit.  Future purchases of KCl will be based upon several factors,

19

including but not limited to, the cost of utilizing the sourced KCl in our SOP process and SOP and KCl market prices. We currently expect to continue to supplement our pond-based SOP production as long as it is economically feasible to do so.

General

We contract bulk shipping vessels, barge, trucking and rail services to move products from our production facilities to distribution outlets and customers.  Our North American salt mines and SOP production facilities are near either water or rail transport systems, which reduces our shipping and handling costs compared to alternative methods of distribution. However, shipping and handling costs still account for a relatively large portion of the total delivered cost of our products.  Fuel prices declined in the latter half of 2014 and declined further in the first quarter of 2015.  In addition, portions of the transportation industry have recently been impacted by supply constraints, particularly the trucking and rail sectors, which have increased costs in 2015 in some of our service regions.  Future period shipping and handling per-unit costs will continue to be influenced by oil-based fuel costs and transportation supply constraints.

Manpower costs, energy costs, packaging, and certain raw material costs, particularly KCl, which can be used to make a portion of our SOP, deicing and water conditioning products, are also significant.  Our production workforce is typically represented by labor unions with multi-year collective bargaining agreements.  Our energy costs result from the consumption of electricity with relatively stable, rate-regulated pricing, and natural gas, which can have significant pricing volatility. We manage the pricing volatility of our natural gas purchases with natural gas forward swap contracts up to 36 months in advance of purchases, helping to reduce the impact of short-term spot market price volatility.

The consolidated financial statements have been prepared to present the historical financial condition and results of operations and cash flows for the Company which include our salt segment, plant nutrition segment, our records management business and unallocated corporate activities.  The results of operations for Compass Manitoba have been included in our plant nutrition segment results from the date of acquisition. The results of operations of the records management business and other incidental revenues include sales of $2.7 million in each period for the three months ended March 31, 2015 and 2014, and are not material to our consolidated financial statements and consequently, are not included in the table below.  The following tables and discussion should be read in conjunction with the information contained in our consolidated financial statements and the accompanying notes included elsewhere in this quarterly report.

Three Months Ended March 31, 2015 Compared to Three Months Ended March 31, 2014

Sales

Sales for the first quarter of 2015 of $393.0 million decreased $29.0 million, or 7% compared to $422.0 million for the same quarter of 2014. Sales primarily include revenues from the sale of our salt and plant nutrition products and shipping and handling costs incurred to deliver salt and plant nutrition products to our customers, or “product sales,” and revenues from our records management business.  Shipping and handling costs were $101.9 million during the first quarter of 2015, a decrease of $28.8 million or 22% compared to $130.7 million for the same quarter of 2014.  The decrease in shipping and handling costs is primarily due to lower salt and plant nutrition sales volumes and lower per-unit shipping and handling costs in the first quarter of 2015 compared to the same quarter of 2014.

Product sales for the first quarter of 2015 of $288.4 million decreased $0.2 million compared to $288.6 million for the same period in 2014, reflecting lower salt segment product sales offset by higher plant nutrition segment product sales.

Salt product sales for the first quarter of 2015 of $222.2 million decreased $7.9 million, or 3% compared to $230.1 million for the same period in 2014.  The decrease in the first quarter of 2015 was due primarily to a decrease in highway and consumer and industrial product sales volumes, which unfavorably impacted salt product sales by approximately $47 million. Salt sales volumes in the first quarter of 2015 decreased by approximately 1.0 million tons from the same period in 2014 due principally to lower highway and consumer deicing sales volumes.  The winter weather experienced in the first quarter of 2014 was more severe in the markets we serve in North America compared to the winter weather experienced in the first quarter of 2015. In addition, the exchange rates used to translate our operations denominated in foreign currencies into U.S. dollars in the first quarter of 2015 unfavorably impacted salt product sales by approximately $8 million compared to the exchange rates used in the first quarter of 2014.  The decrease in salt product sales was offset partially by an increase in highway salt deicing average selling prices which favorably impacted salt product sales by approximately $48 million due primarily to higher contract sales prices compared to the prior year and higher sales volumes in the U.K in the first quarter of 2015.

Plant nutrition product sales during the first quarter of 2015 of $66.2 million increased $7.7 million, or 13% compared to $58.5 million for the same period in 2014.  The increase in plant nutrition product sales was due to 23% increase in average selling price realized during the first quarter of 2015 compared to the first quarter of 2014, which was offset partially by a 9% decrease in sales volumes.  The average selling price for plant nutrition products benefited from higher market prices for SOP products in the first quarter of 2015 compared to the first quarter of 2014.  In addition, the acquisition of Wolf Trax, Inc. increased our average sales price in the first quarter of 2015.

Gross Profit

Gross profit for the first quarter of 2015 of $113.2 million increased $20.9 million, or 23% compared to $92.3 million in the same period of 2014.  As a percent of sales, gross margin increased by seven percentage points, from 22% in the first quarter of 2014 to 29% in the first quarter of 2015.  The gross profit for the salt segment increased by approximately $13 million due primarily to higher average selling prices for highway deicing products, which was offset partially by lower salt sales volumes. Salt per-unit costs were unfavorably impacted by unplanned downtime at our North American mines in the first quarter of 2015, additional costs of $2 million related to a settlement of a 2010 labor dispute and purchased salt used to supplement our production as a result of the more severe winter in the first quarter of 2014.  In addition, the effects of exchange rates used to translate our operations denominated in foreign currencies into U.S. dollars in the first quarter of 2015 unfavorably impacted salt gross profit by approximately $2 million compared to the exchange rates used in the first quarter of 2014.

The increase in plant nutrition segment gross profit of approximately $7 million in the first quarter of 2015 was principally due to higher average sales prices compared to the same period in the prior year. Both periods were impacted by higher per-unit production costs as we purchased and consumed KCl and other mineral feedstock to supplement production although costs in the first quarter of 2015 were elevated compared to the same period in 2014.

Selling, General and Administrative Expenses

Selling, general and administrative expenses for the first quarter of 2015 of $28.5 million increased $3.2 million, or 13% compared to $25.3 million for the same period in 2014, and increased to 7.3% from 6.0% as a percentage of sales. The increase in expense in the first quarter of 2015 is primarily related to higher costs in our plant nutrition segment due to the increased costs associated with the ongoing operation of our Compass Manitoba business which totaled approximately $3.5 million and higher expenses in corporate and other due to investment in information technology.  These increases were offset partially by lower professional expenses in both segments.

Interest Expense

Interest expense for the first quarter of 2015 of $5.4 million increased $1.0 million compared to $4.4 million for the same period in 2014.  This increase in interest expense is primarily due to the refinancing of our $100.0 million 8% senior notes with $250.0 million senior notes (“4.875% Senior Notes”) in June 2014.

21

Other Income, Net

Other income was $3.5 million for the first quarter of 2015 compared to income of $3.1 million in the first quarter of 2014.  Net foreign exchange gains increased from $2.7 million in the first quarter of 2014 to $3.3 million in the first quarter of 2015.

Income Tax Expense

Income tax expense for the first quarter of 2015 was $22.2 million, an increase of $6.7 million compared to $15.5 million for the same quarter of 2014 due to higher pretax income.  In addition, our effective rate is impacted by permanent tax deductions which have a less favorable impact as pretax income increases. Our 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 tax rate differentials, foreign mining taxes, domestic manufacturing deductions, and interest expense recognition differences for book and tax purposes.

Liquidity and Capital Resources

Historically, we have used cash generated from operations to meet our working capital needs, to fund capital expenditures, to pay dividends and to repay our debt. Principally due to the nature of our deicing business, our cash flows from operations are seasonal, with the majority of our cash flows from operations generated during the first half of the calendar year.  When we have not been able to meet our short-term liquidity or capital needs with cash from operations, whether as a result of the seasonality of our business or other causes, we have met those needs with borrowings under our $125 million revolving credit facility.  We expect to meet the ongoing requirements for debt service, any declared dividends and capital expenditures from these sources. This, to a certain extent, is subject to general economic, financial, competitive, legislative, regulatory and other factors that are beyond our control.

Cash and cash equivalents of $313.8 million as of March 31, 2015 increased $47.0 million over December 31, 2014.  We generated $122.4 million of operating cash flows in the first quarter of 2015.  We used a portion of those cash flows to fund capital expenditures of $41.7 million and to pay dividends on our common stock of $22.4 million.

As of March 31, 2015, we had $625.4 million of principal indebtedness consisting of $250.0 million 4.875% Senior Notes due 2024 and $375.4 million of borrowings outstanding under our credit agreement.  No amounts were outstanding under our $125 million revolving credit facility as of March 31, 2015. We had $6.4 million of outstanding letters of credit as of March 31, 2015, which reduced our revolving credit facility borrowing availability to $118.6 million.

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 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, including the total leverage ratio and interest coverage ratio, in order to make payments on our 4.875% Senior Notes or pay dividends to our stockholders.  We must also comply with the terms of our indenture.  Although we are in compliance with our debt covenants as of March 31, 2015, 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 the 4.875% Senior Notes, 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 assure you that we will be able to refinance any of our indebtedness on commercially reasonable terms or at all.

We have been able to manage our cash flows generated and used across the Company to permanently reinvest earnings in our foreign jurisdictions or efficiently repatriate those funds to the U.S.  As of March 31, 2015, we had $74.8 million of cash and cash equivalents (in the consolidated balance sheets) that was either held directly or indirectly by foreign subsidiaries.  Due in large part to the seasonality of our deicing salt business, we experience large changes in our working capital requirements from quarter to quarter.  Typically, our consolidated working capital requirements are the highest in the fourth quarter and lowest in the second quarter.  When needed, we fund short-term working capital requirements by accessing our $125 million revolving credit facility.  Due to our ability to generate adequate levels of domestic cash flow on an annual basis, it is our current intention to permanently reinvest our foreign earnings outside of the U.S.  However, if we were to repatriate our foreign earnings to the U.S., we may be required to accrue and pay U.S. taxes in accordance with the applicable U.S. tax rules and regulations as a result of the repatriation.  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, to some extent, impacted by the values charged on the transfer of our products between them.  We calculate values charged on transfers based on guidelines established by the multi-national organization which publishes accepted tax guidelines recognized in all of the jurisdictions in which we operate, and those calculated values are the basis

22

upon which our subsidiary income taxes, profits and cash flows are realized.  Some of our calculated values have been approved by taxing authorities for certain periods while the values for those same periods or different periods have been challenged by the same or other taxing authorities.  While we believe our calculations are proper and consistent with the accepted guidelines, we can make no assurance that the final resolution of these matters with all of the relevant taxing authorities will be consistent with our existing calculations and resulting financial statements.  Additionally, the timing for settling these challenges may not occur for many 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 impact the amount of earnings attributable to our domestic and foreign subsidiaries, which could impact the amount of permanently reinvested earnings and the tax-efficient access to consolidated cash on hand in all jurisdictions, as well as future cash flows from operations.

See Note 5 to our Consolidated Financial Statements for a discussion regarding our Canadian tax reassessments.  See Note 7 to our Consolidated Financial Statements for a discussion regarding labor and litigation matters.

For the Three Months Ended March 31, 2015 and 2014

Net cash flows provided by operating activities for the three months ended March 31, 2015 were $122.4 million, a decrease of $38.3 million compared to $160.7 million for the first quarter of 2014. We had a reduction in working capital items of $34.3 million in the first quarter of 2015 compared to a reduction of $84.5 million in the first quarter 2014. These reductions provided a portion of our cash flows from operations, and reflect the seasonal nature of our deicing products and will vary largely due to the severity and timing of the winter weather in our regions.

Net cash flows used by investing activities of $41.7 million and $13.4 million for the three months ended March 31, 2015 and 2014, respectively, resulted from capital expenditures of $41.7 million and $25.0 million, respectively.  In addition, we received $8.7 million of insurance advances that were presented as investment activities during the first quarters of 2014 related to a tornado that struck our salt mine and salt mechanical evaporation plant in Goderich, Ontario in 2011.

Financing activities during the first quarter of 2015 used $21.1 million of cash flows, primarily to make $22.4 million of dividend payments and $0.9 million of debt payments.  During the first quarter of 2014, we used $19.2 million of cash flows, primarily to make $20.2 million of dividend payments and $0.9 million of debt payment.  Both periods were offset partially by proceeds received from stock option exercises.

Sensitivity Analysis Related to EBITDA and Adjusted EBITDA

Management uses a variety of measures to evaluate the performance of CMI.  While the 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 EBITDA adjusted for items which management believes are not indicative of our ongoing operating performance (“Adjusted EBITDA”).  Both EBITDA and Adjusted EBITDA are non-GAAP financial measures used to evaluate the operating performance of our core business operations. Our resource allocation, financing methods and cost of capital, and income tax positions are managed at a corporate level, apart from the activities of the operating segments, and the operating facilities are located in different taxing jurisdictions, which can cause considerable variation in net earnings.  We also use EBITDA and Adjusted EBITDA to assess our operating performance and return on capital, and to evaluate potential acquisitions or other capital projects.  EBITDA and Adjusted EBITDA are not calculated under U.S. GAAP and should not be considered in isolation or as a substitute for net 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 in other (income) expense.  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.  The calculation of EBITDA and Adjusted EBITDA as used by management is set forth in the table below (in millions).

	Three Months Ended March 31,
	2015			2014
Net earnings	$	60.6		$	50.2
Interest expense		5.4			4.4
Income tax expense		22.2			15.5
Depreciation, depletion and amortization		19.1			18.4
EBITDA		107.3			88.5
Adjustments to EBITDA:
Other income, net		(3.5	)		(3.1	)
Adjusted EBITDA	$	103.8		$	85.4

Our operating earnings were favorably impacted in the first quarter of 2014 and unfavorably impacted in the first quarter of 2015 by winter weather in the markets we serve.

Recent Accounting Pronouncements

In April 2015, the Financial Accounting Standards Board (“FASB”) issued guidance which requires debt issuance costs to be presented in the balance sheet as a direct deduction from the related debt liability rather than an asset.  The recognition and measurement guidance for debt issuance costs are not affected by this guidance.  This new guidance is effective retrospectively for fiscal years, and interim periods within those years, beginning after December 15, 2015.  Early adoption is permitted.  We do not expect that this guidance will have a material impact on our consolidated financial statements.

In August 2014, the FASB issued guidance which requires management to evaluate whether there is substantial doubt about an entity’s ability to continue as a going concern and to provide disclosure in the footnotes under certain circumstances.  This guidance is effective for fiscal years ending after December 15, 2016 with early adoption permitted.  We do not expect that this guidance will have a material impact on our consolidated financial statements.

In May 2014, the FASB issued guidance to provide a single, comprehensive revenue recognition model for all contracts with customers.  The new revenue recognition model supersedes existing revenue recognition guidance and requires revenue recognition to depict the transfer of promised goods or services to customers in an amount that reflects the consideration an entity expects to receive in exchange for those goods or services.  This guidance is effective for fiscal years and interim periods with those years beginning after December 15, 2016 and early adoption is not permitted.  The guidance permits the use of either a full or modified retrospective or cumulative effect transition method.  We are currently evaluating the impact that the implementation of this standard will have on our consolidated financial statements.

Effects of Currency Fluctuations

We conduct operations in Canada 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 enter 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 historical 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 our revenues and costs are denominated in U.S. dollars, with British pounds sterling and Canadian dollars also being significant. Significant changes in the value of the Canadian dollar or British pound sterling relative to the U.S. dollar could have a material adverse 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 in which we operate.

Seasonality

We experience a substantial amount of seasonality in our sales, primarily with respect to our deicing products.  Consequently, sales and operating income are generally higher in the first and fourth quarters and lower during the second and third quarters of each calendar 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.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

Our business is subject to various types of market risks that include, but are not limited to, interest rate risk, foreign currency exchange rate risk and commodity pricing risk. Management has taken actions to mitigate our exposure to commodity pricing by entering into forward derivative instruments, and may take further actions to mitigate our exposure to interest rates and to 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, 2014.

Item 4. Controls and Procedures

Evaluation of Disclosure Controls and Procedures – As of the end of the period covered by this report, 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 Exchange Act) was performed under the supervision and with the participation of the Company’s management, including the CEO and CFO. Based on that evaluation, the Company’s CEO and CFO concluded that the Company’s disclosure controls and procedures were effective as of March 31, 2015 to ensure that information required to be disclosed in the reports it files and submits under the Securities Exchange Act of 1934 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 CEO and CFO, 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

From time to time, we are involved in various routine legal proceedings. These primarily involve commercial claims, product liability claims, personal injury claims and workers’ compensation claims. We cannot predict the outcome of these lawsuits, legal proceedings and claims with certainty. Nevertheless, we believe that the outcome of these proceedings, even if determined adversely, would not have a material adverse effect on our business, financial condition and results of operations. There have been no material developments during 2015 with respect to legal proceedings other than the matter discussed below.

In December 2009, a surface salt storage dome which was under construction collapsed at the Company’s mine in Goderich, Ontario. The Company was involved in construction litigation and other contract claims with the contractor and engineering firm relating to the dome’s collapse.  Claims asserted against the Company totaled approximately $13 million.  The Company also counterclaimed for damages and withheld payment for some invoices. In the first quarter of 2015, the parties have agreed to settle this matter for a $4.2 million cash payment by the Company, most of which was for the payment of invoices.  As a result, the Company has recognized a gain of approximately $0.7 million in its consolidated financial statements.
