UNITED STATES LIME & MINERALS, INC. AND SUBSIDIARIES

Notes to Condensed Consolidated Financial Statements

(Unaudited)

1.Basis of Presentation

The condensed consolidated financial statements included herein have been prepared by United States Lime & Minerals, Inc. (the “Company”) without independent audit.  In the opinion of the Company’s management, all adjustments of a normal and recurring nature necessary to present fairly the financial position, results of operations, comprehensive income and cash flows for the periods presented have been made.  Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America (“US GAAP”) have been condensed or omitted.  These condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the period ended December 31, 2013.  The results of operations for the three-month period ended March 31, 2014 are not necessarily indicative of operating results for the full year.

2.    Organization

The Company is headquartered in Dallas, Texas, and operates through two business segments.  Through its Lime and Limestone Operations, the Company is a manufacturer of lime and limestone products, supplying primarily the construction, (including highway, road and building contractors), metals (including steel producers), environmental (including municipal sanitation and water treatment facilities and flue gas treatment), oil and gas services, industrial (including paper and glass manufacturers), roof shingle and agriculture (including poultry and cattle feed producers) industries.  The Company operates lime and limestone plants and distribution facilities in Arkansas, Colorado, Louisiana, Oklahoma and Texas through its wholly owned subsidiaries, Arkansas Lime Company, Colorado Lime Company, Texas Lime Company, U.S. Lime Company, U.S. Lime Company — Shreveport, U.S. Lime Company — St. Clair and U.S. Lime Company — Transportation.

The Company’s Natural Gas Interests segment is held in its wholly owned subsidiary, U.S. Lime Company — O & G, LLC (“U.S. Lime O & G”).  Under a lease agreement (the “O & G Lease”), U.S. Lime O & G has royalty interests ranging from 15.4% to 20% and a 20% non-operating working interest, resulting in an overall average revenue interest of 34.7%, with respect to oil and gas rights in 33 wells currently producing on the Company’s approximately 3,800 acres of land located in Johnson County, Texas, in the Barnett Shale Formation. Through U. S. Lime O & G, the Company also has a drillsite and production facility lease agreement and subsurface easement (the “Drillsite Agreement”) relating to approximately 538 acres of land contiguous to the Company’s Johnson County, Texas property.  Pursuant to the Drillsite Agreement, the Company receives a 3% royalty interest and a 12.5% non-operating working interest, resulting in a 12.4% revenue interest, in the six wells currently producing from pad sites located on the Company’s property.

3.    Accounting Policies

Revenue Recognition.  The Company recognizes revenue for its Lime and Limestone Operations in accordance with the terms of its purchase orders, contracts or purchase agreements, which are generally upon shipment, and when payment is considered probable. Revenues include external freight billed to customers with related costs in cost of revenues.  The Company’s returns and allowances are minimal.  External freight billed to customers included in first quarter 2014 and 2013 revenues was $6.5 million and $6.0 million, respectively, which approximates the amount of external freight billed to customers included in cost of revenues.  Sales taxes billed to customers are not included in revenues.  For its Natural Gas Interests, the Company recognizes revenue in the month of production and delivery.

6

Successful-Efforts Method Used for Natural Gas Interests.  The Company uses the successful-efforts method to account for oil and gas exploration and development expenditures.  Under this method, drilling, completion and workover costs for successful exploratory wells and all development well costs are capitalized and depleted using the units-of-production method.  Costs to drill exploratory wells that do not find proved reserves are expensed.

Fair Values of Financial Instruments.  Fair value is defined as “the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date.”  The Company uses a three-tier fair value hierarchy, which classifies the inputs used in measuring fair values, in determining the fair value of its financial assets and liabilities.  These tiers include:  Level 1, defined as observable inputs such as quoted prices for identical instruments in active markets; Level 2, defined as observable inputs other than Level 1 prices such as quoted prices for similar assets or liabilities, quoted prices in markets that are not active, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities; and Level 3, defined as unobservable inputs in which little or no market data exists, therefore requiring an entity to develop its own assumptions.  There were no changes in the methods and assumptions used in measuring fair value during the period, which include, as of the valuation date, quoted three-month LIBOR rates for the remaining life of the interest rate swaps.  The Company’s financial liabilities measured at fair value on a recurring basis at March 31, 2014 and December 31, 2013 are summarized below (in thousands):

							Significant Other Observable Inputs (Level 2)
	March 31, 2014			December 31, 2013			March 31, 2014			December 31, 2013			Valuation Technique
Interest rate swap liabilities	$	(1,304	)	$	(1,533	)	$	(1,304	)	$	(1,533	)	Cash flows approach

Comprehensive Income (Loss).  Accounting principles generally require that recognized revenue, expenses, gains and losses be included in net income.  Certain changes in assets and liabilities, such as mark-to-market gains or losses of interest rate hedges, are reported as a separate component of the equity section of the balance sheet.  Such items, along with net income, are components of comprehensive income (loss).

4.   Business Segments

The Company has identified two business segments based on the distinctness of their activities and products:  Lime and Limestone Operations and Natural Gas Interests.  All operations are in the United States.  In evaluating the operating results of the Company’s segments, management primarily reviews revenues and gross profit.  The Company does not allocate corporate overhead or interest costs to its business segments.

	6,809		8,487
Service parts inventories	5,183		5,201
	$	11,992	$	13,688

8.  Banking Facilities and Debt

The Company’s credit agreement includes a ten-year $40 million term loan (the “Term Loan”), a ten-year $20 million multiple draw term loan (the “Draw Term Loan”) and a $30 million revolving credit facility (the “Revolving Facility”) (collectively, the “Credit Facilities”).  At March 31, 2014, the Company had $0.7 million of letters of credit issued, which count as draws under the Revolving Facility.  Pursuant to a security agreement, dated August 25, 2004, the Credit Facilities are secured by the Company’s existing and hereafter acquired tangible assets, intangible assets and real property.

The Term Loan requires quarterly principal payments of $0.8 million, with a final principal payment of $10.0 million due on December 31, 2015.  The Draw Term Loan requires quarterly principal payments of $0.4 million, with a final principal payment of $6.7 million due on December 31, 2015.  The maturity of the Term Loan, the Draw Term Loan and the Revolving Facility can be accelerated if any event of default, as defined under the Credit Facilities, occurs.

The Revolving Facility commitment fee ranges from 0.250% to 0.400%.  The Credit Facilities bear interest, at the Company’s option, at either LIBOR plus a margin of 1.750% to 2.750%, or the Lender’s Prime Rate plus a margin of 0.000% to plus 1.000%.  The Revolving Facility commitment fee and the interest rate margins are determined quarterly in accordance with a pricing grid based upon the Company’s Cash Flow Leverage Ratio, defined as the ratio of the Company’s total funded senior indebtedness to earnings before interest, taxes, depreciation, depletion and amortization (“EBITDA”) for the 12 months ended on the last day of the most recent calendar quarter, plus pro forma EBITDA from any businesses acquired during the period.

The Company has hedges, with Wells Fargo Bank, N.A as the counterparty to the hedges, that fix LIBOR through maturity at 4.695%, 4.875% and 5.500% on the outstanding balance of the Term Loan, 75% of the outstanding balance of the Draw Term Loan and 25% of the outstanding balance of the Draw Term Loan, respectively.  Based on the current LIBOR margin of 1.750%, the Company’s current interest rates are: 6.445% on the outstanding balance of the Term Loan; 6.625% on 75% of the outstanding balance of the Draw Term Loan; and 7.250% on 25% of the outstanding balance of the Draw Term Loan.

9

The hedges have been effective as defined under applicable accounting rules.  Therefore, changes in fair value of the interest rate hedges are reflected in comprehensive income (loss).  The Company will be exposed to credit losses in the event of non-performance by the counterparty to the hedges.  The Company’s mark to market of its interest rate hedges, at March 31, 2014 and December 31, 2013, resulted in liabilities of $1.3 million and $1.5 million, respectively, which are included in accrued expenses ($0.9 million at each date) and other liabilities ($0.4 million and $0.6 million, respectively) on the Company’s Condensed Consolidated Balance Sheets.  The Company paid $0.2 million and $0.3 million in the first quarters 2014 and 2013, respectively, in quarterly settlement payments pursuant to the hedges.  These payments are included in interest expense on the Company’s Condensed Consolidated Statements of Operations.

A summary of outstanding debt at the dates indicated is as follows (in thousands):

	March 31,		December 31,
	2014		2013
Term Loan	$	12,500	$	13,334
Draw Term Loan	7,917		8,337
Revolving Facility (1)	—		—
Subtotal	20,417		21,667
Less current installments	5,000		5,000
Debt, excluding current installments	$	15,417	$	16,667

(1) The Company had letters of credit totaling $660 issued on the Revolving Facility at both March 31, 2014 and December 31, 2013.

As the Company’s debt bears interest at floating rates, the Company estimates that the carrying values of its debt at March 31, 2014 and December 31, 2013 approximate fair value.

9.  Income Taxes

The Company has estimated that its effective income tax rate for 2014 will be approximately 25.2%.  As in prior periods, the primary reason for the effective rate being below the federal statutory rate is due to statutory depletion, which is allowed for income tax purposes and is a permanent difference between net income for financial reporting purposes and taxable income.

10. Dividend

On March 20, 2014, the Company paid $0.7 million in cash dividends, based on a dividend of $0.125 (12.5 cents) per share on its common stock, to shareholders of record at the close of business on February 28, 2014.

11. Subsequent Event

On April 30, 2014, the Company declared a regular quarterly cash dividend of $0.125 (12.5 cents) per share on the Company’s common stock.  This dividend is payable on June 20, 2014 to shareholders of record at the close of business on May 30, 2014.

Overview.

The Company has two operating segments:  Lime and Limestone Operations and Natural Gas Interests.  Revenues and gross profit are the primary items utilized to evaluate the operating results of the Company’s segments and to allocate resources.

Through its Lime and Limestone Operations, the Company is a manufacturer of lime and limestone products, supplying primarily the construction (including highway, road and building contractors), metals (including steel producers), environmental (including municipal sanitation and water treatment facilities and flue gas treatment), oil and gas services, industrial (including paper and glass manufacturers), roof shingle and agriculture (including poultry and cattle feed producers) industries.  The Company is headquartered in Dallas, Texas and operates lime and limestone plants and distribution facilities in Arkansas, Colorado, Louisiana, Oklahoma and Texas through its wholly owned subsidiaries, Arkansas Lime Company, Colorado Lime Company, Texas Lime Company, U.S. Lime Company, U.S. Lime Company — Shreveport, U.S. Lime Company — St. Clair and U.S. Lime Company — Transportation.  The Lime and Limestone Operations represent the Company’s principal business.

11

The Company’s Natural Gas Interests are held in its wholly owned subsidiary, U.S. Lime Company — O & G, LLC, and consist of royalty and non-operating working interests under the O & G Lease with EOG Resources, Inc. and the Drillsite Agreement with XTO Energy, Inc. related to the Company’s Johnson County, Texas property, located in the Barnett Shale Formation, on which Texas Lime Company conducts its lime and limestone operations.

Revenues from the Company’s Lime and Limestone Operations increased 16.2% in the first quarter 2014, compared to the first quarter 2013, because of increased sales volumes of approximately 14.9% for the Company’s lime and limestone products, primarily resulting from the increase in demand from its construction, industrial and environmental customers, and average product price increases of approximately 1.3% realized for the Company’s lime and limestone products in the first quarter 2014, compared to the comparable 2013 quarter.  The Company’s gross profit from its Lime and Limestone Operations increased 35.2% in the first quarter 2014, compared to the first quarter 2013, primarily because of the increase in revenues in the first quarter 2014, compared to the comparable 2013 quarter.

Revenues from the Company’s Natural Gas Interests increased 14.7% in the first quarter 2014, primarily due to increased prices for natural gas, compared to the comparable 2013 quarter.  This increase was partially offset by decreased production volumes resulting from the normal declines in production rates on the Company’s 39 existing natural gas wells.  The increase in revenues from Natural Gas Interests in the first quarter 2014, as compared to last year’s comparable quarter, resulted from price increases (approximately 37.1% for the 2014 quarter, compared to the comparable 2013 quarter), partially offset by decreased production volumes (approximately 22.4% for the 2014 quarter, compared to the comparable 2013 quarter).  The Company’s gross profit from its Natural Gas Interests increased 49.0% in the first quarter 2014, compared to the comparable 2013 quarter, primarily because of the increase in revenues discussed above.

The Company’s continued significant cash flows and strong balance sheet enabled it to declare and pay in the first quarter 2014 a regular quarterly cash dividend of $0.125 (12.5 cents) per share on its common stock.

Liquidity and Capital Resources.

Net cash provided by operating activities was $3.8 million in the first quarter 2014, compared to $5.4 million in the first quarter 2013, a decrease of $1.6 million, or 29.6%.  Net cash provided by operating activities is composed of net income, depreciation, depletion and amortization (“DD&A”) and other non-cash items included in net income, and changes in working capital.  In the first quarter 2014, cash provided by operating activities was principally composed of net income of $4.5 million and DD&A of $3.6 million, compared to $2.8 million of net income and $3.7 million of DD&A in the first quarter 2013.  The most significant changes in working capital in the 2014 and 2013 quarters were net increases in trade receivables of $4.7 million and $2.2 million and decreases in inventories of $1.7 million and $0.4 million, respectively, and a $1.4 million decrease in accounts payable and accrued expenses in the 2014 quarter, compared to a $0.6 million increase in the 2013 quarter.  The net increases in trade receivables in the 2014 and 2013 periods primarily resulted from increased revenues in the last month of the first quarters compared to the corresponding last month of the prior year fourth quarters.

The Company had $2.9 million in capital expenditures in the first quarter 2014, compared to $1.5 million in the comparable period last year.

Net cash used in financing activities was $2.0 million and $0.2 million in the 2014 and 2013 quarters, respectively, primarily consisting of repayment of $1.25 million of term loan debt in the 2014 quarter (because March 31, 2013 was not a business day, the first quarter 2013 $1.25 million repayment of term loan debt was made on April 1, 2013) and $0.1 million and $0.2 million for purchase of treasury shares in the first quarters 2014 and 2013, respectively.  Additionally, the Company paid $0.7 million in dividends during the first quarter 2014.  Cash and cash equivalents decreased to $48.5 million at March 31, 2014 from $49.5 million at December 31, 2013 primarily because of the $4.7 million net increase in trade receivables discussed above.

12

The Company’s credit agreement includes a ten-year $40 million term loan (the “Term Loan”), a ten-year $20 million multiple draw term loan (the “Draw Term Loan”) and a $30 million revolving credit facility (the “Revolving Facility”) (collectively, the “Credit Facilities”).  At March 31, 2014, the Company had $0.6 million of letters of credit issued, which count as draws under the Revolving Facility.  Pursuant to a security agreement, dated August 25, 2004, the Credit Facilities are secured by the Company’s existing and hereafter acquired tangible assets, intangible assets and real property.

The Term Loan requires quarterly principal payments of $0.8 million, with a final principal payment of $10.0 million due on December 31, 2015.  The Draw Term Loan requires quarterly principal payments of $0.4 million, with a final principal payment of $6.7 million due on December 31, 2015.  The maturity of the Term Loan, the Draw Term Loan and the Revolving Facility can be accelerated if any event of default, as defined under the Credit Facilities, occurs.

The Revolving Facility commitment fee ranges from 0.250% to 0.400%.  The Credit Facilities bear interest, at the Company’s option, at either LIBOR plus a margin of 1.750% to 2.750%, or the Lender’s Prime Rate plus a margin of 0.000% to plus 1.000%.  The Revolving Facility commitment fee and the interest rate margins are determined quarterly in accordance with a pricing grid based upon the Company’s Cash Flow Leverage Ratio, defined as the ratio of the Company’s total funded senior indebtedness to earnings before interest, taxes, depreciation, depletion and amortization (“EBITDA”) for the 12 months ended on the last day of the most recent calendar quarter, plus pro forma EBITDA from any businesses acquired during the period.

The Company has hedges, with Wells Fargo Bank, N.A as the counterparty to the hedges, that fix LIBOR through maturity at 4.695%, 4.875% and 5.500% on the outstanding balance of the Term Loan, 75% of the outstanding balance of the Draw Term Loan and 25% of the outstanding balance of the Draw Term Loan, respectively.  Based on the current LIBOR margin of 1.750%, the Company’s current interest rates are: 6.445% on the outstanding balance of the Term Loan; 6.625% on 75% of the outstanding balance of the Draw Term Loan; and 7.250% on 25% of the outstanding balance of the Draw Term Loan.

The hedges have been effective as defined under applicable accounting rules.  Therefore, changes in fair value of the interest rate hedges are reflected in comprehensive income (loss).  The Company will be exposed to credit losses in the event of non-performance by the counterparty to the hedges.  The Company’s mark to market of its interest rate hedges, at March 31, 2014 and December 31, 2013, resulted in liabilities of $1.3 million and $1.5 million, respectively, which are included in accrued expenses ($0.9 million at each date) and other liabilities ($0.4 million and $0.6 million, respectively) on the Company’s Condensed Consolidated Balance Sheets.  The Company paid $0.2 million and $0.3 million in the first quarters 2014 and 2013, respectively, in quarterly settlement payments pursuant to the hedges.  These payments are included in interest expense on the Company’s Condensed Consolidated Statements of Operations.

The Company is not contractually committed to any planned capital expenditures for its Lime and Limestone Operations until actual orders are placed for equipment.  As of March 31, 2014, the Company had no material open orders or commitments that are not included in current liabilities on the March 31, 2014 Condensed Consolidated Balance Sheet.

As of March 31, 2014, the Company had $20.4 million in total debt outstanding and no draws on its $30 million Revolving Facility other than the $0.7 million of letters of credit.  The Company believes that cash on hand and cash generated from operations will be sufficient to meet the Company’s operating needs, ongoing capital needs, including the capital for possible modernization and development projects, debt service needs and liquidity needs and pay regular cash dividends for the near future.

Results of Operations.

Revenues in the first quarter 2014 increased to $36.7 million from $31.6 million in the first quarter 2013, an increase of $5.1 million, or 16.2%.  Revenues from the Company’s Lime and Limestone Operations in the first quarter 2014 increased $4.9 million, or 16.2%, to $35.1 million from $30.2 million in the comparable 2013 quarter, while revenues from its Natural Gas Interests increased $0.2 million, or 14.7%, to $1.6 million from $1.4 million in the comparable prior year quarter.

The increase in Lime and Limestone Operations revenues in the first quarter 2014 as compared to the first quarter 2013 resulted primarily from increased sales volumes due to increased demand for the Company’s lime and limestone products.  Although some of the increased demand from the Company’s construction customers was to be expected after the postponement of certain construction projects in the fourth quarter 2013 due to the inclement weather, there was also increased demand in the first quarter 2014 for other construction projects as well as from the Company’s industrial and environmental customers.  Production volumes from the Company’s Natural Gas Interests for the first quarter 2014 totaled 218 thousand MCF, sold at an average price of $7.52 per MCF, compared to 261 thousand MCF, sold at an average price of $5.49 per MCF, in the comparable 2013 quarter.  The Company’s average price per MCF in the first quarter 2014 was higher than its average price in the first quarter 2013 primarily due to increases in natural gas prices.

The Company’s gross profit in the first quarter 2014 was $8.6 million, compared to $6.3 million in the comparable 2013 quarter, an increase of $2.3 million, or 36.6%.  Included in gross profit for the 2014 quarter was $7.7 million from the Company’s Lime and Limestone Operations, compared to $5.7 million in the comparable 2013 quarter, an increase of $2.0 million, or 35.2%.  The increase in gross profit for the Company’s Lime and Limestone Operations in the first quarter 2014 compared to the first quarter 2013 resulted primarily from the increase in revenues discussed above.  Gross profit from the Company’s Natural Gas Interests was $0.9 million in the first quarter 2014, compared to $0.6 million in the comparable 2013 quarter, an increase of $0.3 million, or 49.0%, due to the increase in revenues discussed above.

Selling, general and administrative expenses (“SG&A”) were $2.2 million in the first quarter 2014, compared to $2.1 million in the first quarter 2013, an increase of $39 thousand, or 1.8%. As a percentage of revenues, SG&A decreased to 6.0% in the first quarter 2014, compared to 6.8% in the first quarter 2013 primarily due to the increase in revenues in the 2014 quarter, compared to the comparable 2013 quarter.

Interest expense in the first quarter 2014 decreased $0.1 million, or 18.4% to $0.4 million from $0.5 million in the first quarter 2013, resulted from decreased average outstanding debt due to the repayment of debt since March 31, 2013.  Interest expense in the first quarter 2014 included $0.2 million in quarterly settlement payments on the Company’s hedges, compared to $0.3 million of such settlement payments in the comparable 2013 quarter.

Income tax expense increased to $1.5 million in the first quarters 2014 from $0.9 million in the first quarter 2013, an increase of $0.6 million, or 61.2%.  The increase in income taxes was primarily due to the increase in the Company’s income before taxes in the first quarter 2014, compared to the first quarter 2013.

The Company’s net income was $4.5 million ($0.80 per share diluted) in the first quarter 2014, compared to net income of $2.8 million ($0.50 per share diluted) in the first quarter 2013, an increase of $1.7 million, or 62.9%.

ITEM 3:QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Interest Rate Risk.

The Company is exposed to changes in interest rates, primarily as a result of floating interest rates on the Term Loan, Draw Term Loan and Revolving Facility.  At March 31, 2014, the Company had $20.4 million of indebtedness outstanding under floating rate debt. The Company has entered into interest rate hedge agreements to swap floating rates for fixed rates at 4.695%, plus the applicable LIBOR margin, through maturity on the Term Loan balance of $12.5 million, 4.875%, plus the applicable LIBOR margin, on $5.9 million of the Draw Term Loan balance and 5.50%, plus the applicable LIBOR margin, on $2.0 million of the Draw Term Loan balance.  There was no outstanding balance on the Revolving Facility subject to interest rate risk at March 31, 2014.  Any future borrowings under the Revolving Facility would be subject to interest rate risk.  See Note 8 of Notes to Condensed Consolidated Financial Statements.

ITEM 4:CONTROLS AND PROCEDURES

The Company’s management, with the participation of the Company’s Chief Executive Officer (“CEO”) and Chief Financial Officer (“CFO”), evaluated the effectiveness of the Company’s disclosure controls and procedures as of the end of the period covered by this Report.  Based on that evaluation, the CEO and CFO concluded that the Company’s disclosure controls and procedures as of the end of the period covered by this Report were effective.

No change in the Company’s internal control over financial reporting occurred during the Company’s most recent 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 2:UNREGISTERED SALES OF EQUITY SECURITIES AND USE OF PROCEEDS

The Company’s Amended and Restated 2001 Long-Term Incentive Plan allows employees and directors to pay the exercise price for stock options and the tax withholding liability upon the lapse of restrictions on restricted stock by payment in cash and/or delivery of shares of the Company’s common stock.  In the first quarter 2014, pursuant to these provisions, the Company received 1,464 shares of its common stock for the payment of tax withholding liability upon the lapse of restrictions on restricted stock.  The 1,464 shares were valued at $54.01 to $54.55 per share (weighted average of $54.40 per share), the fair market value of one share of the Company’s common stock on the date that they were tendered to the Company.

ITEM 4:MINE SAFETY DISCLOSURES

Under Section 1503(a) of the Dodd-Frank Wall Street Reform and Consumer Protection Act and Item 104 of SEC Regulation S-K, each operator of a coal or other mine is required to include disclosures regarding certain mine safety results in its periodic reports filed with the SEC.  The operation of the Company’s quarries, underground mine and plants is subject to regulation by the federal Mine Safety and Health Administration (“MSHA”) under the Federal Mine Safety and Health Act of 1977.  The required information regarding certain mining safety and health matters, broken down by mining complex, for the quarter ended March 31, 2014 is presented in Exhibit 95.1 to this Report.

The Company believes it is responsible to employees to provide a safe and healthy workplace environment. The Company seeks to accomplish this by: training employees in safe work practices; openly communicating with employees; following safety standards and establishing and improving safe work practices; involving employees in safety processes; and recording, reporting and investigating accidents, incidents and losses to avoid reoccurrence.

Following passage of the Mine Improvement and New Emergency Response Act of 2006, MSHA significantly increased the enforcement of mining safety and health standards on all aspects of mining operations. There has also been an increase in the dollar penalties assessed for citations and orders issued in recent years.

EXHIBIT 95.1

MINE SAFETY DISCLOSURES

The following disclosures are provided pursuant to Section 1503(a) of the Dodd-Frank Wall Street Reform and Consumer Protection Act and Item 104 of SEC Regulation S-K, which require certain disclosures by companies required to file periodic reports under the Securities Exchange Act of 1934, as amended, that operate mines regulated under the Federal Mine Safety and Health Act of 1977 (the “Mine Act”).

The Mine Act has been construed as authorizing MSHA to issue citations and orders pursuant to the legal doctrine of strict liability, or liability without fault. If, in the opinion of an MSHA inspector, a condition that violates the Mine Act or regulations promulgated pursuant to it exists, then a citation or order will be issued regardless of whether the operator had any knowledge of, or fault in, the existence of that condition. Many of the Mine Act standards include one or more subjective elements, so that issuance of a citation or order often depends on the opinions or experience of the MSHA inspector involved and the frequency and severity of citations and orders will vary from inspector to inspector.

Whenever MSHA believes that a violation of the Mine Act, any health or safety standard, or any regulation has occurred, it may issue a citation or order which describes the violation and fixes a time within which the operator must abate the violation. In some situations, such as when MSHA believes that conditions pose a hazard to miners, MSHA may issue an order requiring cessation of operations, or removal of miners from the area of the mine, affected by the condition until the hazards are corrected. Whenever MSHA issues a citation or order, it has authority to propose a civil penalty or fine, as a result of the violation, that the operator is ordered to pay.

The table that follows reflects citations, orders, violations and proposed assessments issued to the Company by MSHA during the quarter ended March 31, 2014 and all pending legal actions as of March 31, 2014. Due to timing and other factors, the data may not agree with the mine data retrieval system maintained by MSHA. The proposed assessments for the quarter ended March 31, 2014 were taken from the MSHA system as of  May 1, 2014.

Additional information follows about MSHA references used in the table:

·Section 104(a) Citations: The total number of citations received from MSHA under section 104(a) of the Mine Act for alleged violations of health or safety standards that could significantly and substantially contribute to a serious injury if left unabated.

·Section 104(b) Orders: The total number of orders issued by MSHA under section 104(b) of the Mine Act, which represents a failure to abate a citation under section 104(a) within the period of time prescribed by MSHA. This results in an order of immediate withdrawal from the area of the mine affected by the condition until MSHA determines that the violation has been abated.

·Section 104(d) Citations and Orders: The total number of citations and orders issued by MSHA under section 104(d) of the Mine Act for unwarrantable failure to comply with mandatory health or safety standards.

·Section 110(b)(2) Violations: The total number of flagrant violations issued by MSHA under section 110(b)(2) of the Mine Act.

·Section 107(a) Orders: The total number of orders issued by MSHA under section 107(a) of the Mine Act for situations in which MSHA determined an imminent danger existed.

Citations and orders can be contested before the Federal Mine Safety and Health Review Commission (the “Commission”), and as part of that process, are often reduced in severity and amount, and are sometimes dismissed.  The Commission is an independent adjudicative agency that provides administrative trial and appellate review of legal disputes arising under the Mine Act. These cases may involve, among other questions, challenges by operators to citations, orders and penalties they have received from MSHA, or complaints of discrimination by miners under section 105 of the Mine Act.

(1)The definition of a mine under section 3 of the Mine Act includes the mine, as well as other items used in, or to be used in, or resulting from, the work of extracting and processing limestone, such as roads, land, structures, facilities, equipment, machines, tools, kilns, and other property. These other items associated with a single mine have been aggregated in the totals for that mine.

(2)The proposed MSHA assessments issued during the reporting period do not necessarily relate to the citations or orders issued by MSHA during the reporting period or to the pending contests reported above.

(3)Includes any pending legal action before the Commission involving such mine as of March 31, 2014. All pending legal actions were initiated by the Company. The pending legal actions may relate to the citations or orders issued by MSHA during the reporting period or to citations or orders issued in prior periods. There were six legal actions instituted and no legal actions resolved during the reporting period.

Pattern or Potential Pattern of Violations. During the quarter ended March 31, 2014, none of the mines operated by the Company received written notice from MSHA of either (a) a pattern of violations of mandatory health or safety standards that are of such nature as could have significantly and substantially contributed to mine health or safety hazards under section 104(e) of the Mine Act or (b) the potential to have such a pattern.

The Company is headquartered in Dallas, Texas, and operates through two business segments.  Through its Lime and Limestone Operations, the Company is a manufacturer of lime and limestone products, supplying primarily the construction, (including highway, road and building contractors), metals (including steel producers), environmental (including municipal sanitation and water treatment facilities and flue gas treatment), oil and gas services, industrial (including paper and glass manufacturers), roof shingle and agriculture (including poultry and cattle feed producers) industries.  The Company operates lime and limestone plants and distribution facilities in Arkansas, Colorado, Louisiana, Oklahoma and Texas through its wholly owned subsidiaries, Arkansas Lime Company, Colorado Lime Company, Texas Lime Company, U.S. Lime Company, U.S. Lime Company — Shreveport, U.S. Lime Company — St. Clair and U.S. Lime Company — Transportation.

The Company’s Natural Gas Interests segment is held in its wholly owned subsidiary, U.S. Lime Company — O & G, LLC (“U.S. Lime O & G”).  Under a lease agreement (the “O & G Lease”), U.S. Lime O & G has royalty interests ranging from 15.4% to 20% and a 20% non-operating working interest, resulting in an overall average revenue interest of 34.7%, with respect to oil and gas rights in 33 wells currently producing on the Company’s approximately 3,800 acres of land located in Johnson County, Texas, in the Barnett Shale Formation. Through U. S. Lime O & G, the Company also has a drillsite and production facility lease agreement and subsurface easement (the “Drillsite Agreement”) relating to approximately 538 acres of land contiguous to the Company’s Johnson County, Texas property.  Pursuant to the Drillsite Agreement, the Company receives a 3% royalty interest and a 12.5% non-operating working interest, resulting in a 12.4% revenue interest, in the six wells currently producing from pad sites located on the Company’s property.

Accounting Policies

Revenue Recognition

Revenue Recognition.  The Company recognizes revenue for its Lime and Limestone Operations in accordance with the terms of its purchase orders, contracts or purchase agreements, which are generally upon shipment, and when payment is considered probable. Revenues include external freight billed to customers with related costs in cost of revenues.  The Company’s returns and allowances are minimal.  External freight billed to customers included in first quarter 2014 and 2013 revenues was $6.5 million and $6.0 million, respectively, which approximates the amount of external freight billed to customers included in cost of revenues.  Sales taxes billed to customers are not included in revenues.  For its Natural Gas Interests, the Company recognizes revenue in the month of production and delivery.

Successful-Efforts Method Used for Natural Gas Interests

Successful-Efforts Method Used for Natural Gas Interests.  The Company uses the successful-efforts method to account for oil and gas exploration and development expenditures.  Under this method, drilling, completion and workover costs for successful exploratory wells and all development well costs are capitalized and depleted using the units-of-production method.  Costs to drill exploratory wells that do not find proved reserves are expensed.

Fair Values of Financial Instruments

Fair Values of Financial Instruments.  Fair value is defined as “the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date.”  The Company uses a three-tier fair value hierarchy, which classifies the inputs used in measuring fair values, in determining the fair value of its financial assets and liabilities.  These tiers include:  Level 1, defined as observable inputs such as quoted prices for identical instruments in active markets; Level 2, defined as observable inputs other than Level 1 prices such as quoted prices for similar assets or liabilities, quoted prices in markets that are not active, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities; and Level 3, defined as unobservable inputs in which little or no market data exists, therefore requiring an entity to develop its own assumptions.  There were no changes in the methods and assumptions used in measuring fair value during the period, which include, as of the valuation date, quoted three-month LIBOR rates for the remaining life of the interest rate swaps.  The Company’s financial liabilities measured at fair value on a recurring basis at March 31, 2014 and December 31, 2013 are summarized below (in thousands):

							Significant Other Observable Inputs (Level 2)
	March 31, 2014			December 31, 2013			March 31, 2014			December 31, 2013			Valuation Technique
Interest rate swap liabilities	$	(1,304	)	$	(1,533	)	$	(1,304	)	$	(1,533	)	Cash flows approach

Comprehensive Income (Loss)

Comprehensive Income (Loss).  Accounting principles generally require that recognized revenue, expenses, gains and losses be included in net income.  Certain changes in assets and liabilities, such as mark-to-market gains or losses of interest rate hedges, are reported as a separate component of the equity section of the balance sheet.  Such items, along with net income, are components of comprehensive income (loss).

8.  Banking Facilities and Debt

The Company’s credit agreement includes a ten-year $40 million term loan (the “Term Loan”), a ten-year $20 million multiple draw term loan (the “Draw Term Loan”) and a $30 million revolving credit facility (the “Revolving Facility”) (collectively, the “Credit Facilities”).  At March 31, 2014, the Company had $0.7 million of letters of credit issued, which count as draws under the Revolving Facility.  Pursuant to a security agreement, dated August 25, 2004, the Credit Facilities are secured by the Company’s existing and hereafter acquired tangible assets, intangible assets and real property.

The Term Loan requires quarterly principal payments of $0.8 million, with a final principal payment of $10.0 million due on December 31, 2015.  The Draw Term Loan requires quarterly principal payments of $0.4 million, with a final principal payment of $6.7 million due on December 31, 2015.  The maturity of the Term Loan, the Draw Term Loan and the Revolving Facility can be accelerated if any event of default, as defined under the Credit Facilities, occurs.

The Revolving Facility commitment fee ranges from 0.250% to 0.400%.  The Credit Facilities bear interest, at the Company’s option, at either LIBOR plus a margin of 1.750% to 2.750%, or the Lender’s Prime Rate plus a margin of 0.000% to plus 1.000%.  The Revolving Facility commitment fee and the interest rate margins are determined quarterly in accordance with a pricing grid based upon the Company’s Cash Flow Leverage Ratio, defined as the ratio of the Company’s total funded senior indebtedness to earnings before interest, taxes, depreciation, depletion and amortization (“EBITDA”) for the 12 months ended on the last day of the most recent calendar quarter, plus pro forma EBITDA from any businesses acquired during the period.

The Company has hedges, with Wells Fargo Bank, N.A as the counterparty to the hedges, that fix LIBOR through maturity at 4.695%, 4.875% and 5.500% on the outstanding balance of the Term Loan, 75% of the outstanding balance of the Draw Term Loan and 25% of the outstanding balance of the Draw Term Loan, respectively.  Based on the current LIBOR margin of 1.750%, the Company’s current interest rates are: 6.445% on the outstanding balance of the Term Loan; 6.625% on 75% of the outstanding balance of the Draw Term Loan; and 7.250% on 25% of the outstanding balance of the Draw Term Loan.

The hedges have been effective as defined under applicable accounting rules.  Therefore, changes in fair value of the interest rate hedges are reflected in comprehensive income (loss).  The Company will be exposed to credit losses in the event of non-performance by the counterparty to the hedges.  The Company’s mark to market of its interest rate hedges, at March 31, 2014 and December 31, 2013, resulted in liabilities of $1.3 million and $1.5 million, respectively, which are included in accrued expenses ($0.9 million at each date) and other liabilities ($0.4 million and $0.6 million, respectively) on the Company’s Condensed Consolidated Balance Sheets.  The Company paid $0.2 million and $0.3 million in the first quarters 2014 and 2013, respectively, in quarterly settlement payments pursuant to the hedges.  These payments are included in interest expense on the Company’s Condensed Consolidated Statements of Operations.

A summary of outstanding debt at the dates indicated is as follows (in thousands):

	March 31,		December 31,
	2014		2013
Term Loan	$	12,500	$	13,334
Draw Term Loan	7,917		8,337
Revolving Facility (1)	—		—
Subtotal	20,417		21,667
Less current installments	5,000		5,000
Debt, excluding current installments	$	15,417	$	16,667

(1) The Company had letters of credit totaling $660 issued on the Revolving Facility at both March 31, 2014 and December 31, 2013.

As the Company’s debt bears interest at floating rates, the Company estimates that the carrying values of its debt at March 31, 2014 and December 31, 2013 approximate fair value.

9.  Income Taxes

The Company has estimated that its effective income tax rate for 2014 will be approximately 25.2%.  As in prior periods, the primary reason for the effective rate being below the federal statutory rate is due to statutory depletion, which is allowed for income tax purposes and is a permanent difference between net income for financial reporting purposes and taxable income.

Revenue Recognition.  The Company recognizes revenue for its Lime and Limestone Operations in accordance with the terms of its purchase orders, contracts or purchase agreements, which are generally upon shipment, and when payment is considered probable. Revenues include external freight billed to customers with related costs in cost of revenues.  The Company’s returns and allowances are minimal.  External freight billed to customers included in first quarter 2014 and 2013 revenues was $6.5 million and $6.0 million, respectively, which approximates the amount of external freight billed to customers included in cost of revenues.  Sales taxes billed to customers are not included in revenues.  For its Natural Gas Interests, the Company recognizes revenue in the month of production and delivery.

Successful-Efforts Method Used for Natural Gas Interests.  The Company uses the successful-efforts method to account for oil and gas exploration and development expenditures.  Under this method, drilling, completion and workover costs for successful exploratory wells and all development well costs are capitalized and depleted using the units-of-production method.  Costs to drill exploratory wells that do not find proved reserves are expensed.

Fair Values of Financial Instruments.  Fair value is defined as “the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date.”  The Company uses a three-tier fair value hierarchy, which classifies the inputs used in measuring fair values, in determining the fair value of its financial assets and liabilities.  These tiers include:  Level 1, defined as observable inputs such as quoted prices for identical instruments in active markets; Level 2, defined as observable inputs other than Level 1 prices such as quoted prices for similar assets or liabilities, quoted prices in markets that are not active, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities; and Level 3, defined as unobservable inputs in which little or no market data exists, therefore requiring an entity to develop its own assumptions.  There were no changes in the methods and assumptions used in measuring fair value during the period, which include, as of the valuation date, quoted three-month LIBOR rates for the remaining life of the interest rate swaps.  The Company’s financial liabilities measured at fair value on a recurring basis at March 31, 2014 and December 31, 2013 are summarized below (in thousands):

							Significant Other Observable Inputs (Level 2)
	March 31, 2014			December 31, 2013			March 31, 2014			December 31, 2013			Valuation Technique
Interest rate swap liabilities	$	(1,304	)	$	(1,533	)	$	(1,304	)	$	(1,533	)	Cash flows approach

Comprehensive Income (Loss).  Accounting principles generally require that recognized revenue, expenses, gains and losses be included in net income.  Certain changes in assets and liabilities, such as mark-to-market gains or losses of interest rate hedges, are reported as a separate component of the equity section of the balance sheet.  Such items, along with net income, are components of comprehensive income (loss).
