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, 2012.  The results of operations for the three- and nine-month periods ended September 30, 2013 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 parking lot 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 drilled and 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 drilled and 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 2013 and 2012 revenues was $7.1 million and $6.7 million for the three-month periods, and $19.8 million and $20.5 million for the nine-month periods, respectively, which approximates the amount of external freight 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 and completion 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, LIBOR rates over the term of the outstanding debt.  The Company’s financial  liabilities measured at fair value on a recurring basis at September 30, 2013 and December 31, 2012 are summarized below (in thousands):

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.

The following table sets forth operating results and certain other financial data for the Company’s two business segments (in thousands):

5.              Income Per Share of Common Stock

The following table sets forth the computation of basic and diluted income per common share (in thousands, except per share amounts):

Amounts reclassified to interest expense were for payments made by the Company pursuant to the Company’s interest rate hedges.

Accumulated other comprehensive loss consisted of the following (in thousands):

7.              Inventories

Inventories are valued principally at the lower of cost, determined using the average cost method, or market.  Costs for raw materials and finished goods include materials, labor, and production overhead.  Inventories consisted of the following (in thousands):

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 September 30, 2013, 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 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.

9

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 upon 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 September 30, 2013 and December 31, 2012, resulted in liabilities of $1.8 million and $2.6 million, respectively, which are included in accrued expenses ($1.0 million and $1.1 million, respectively) and other liabilities ($0.8 million and $1.5 million, respectively) on the Company’s Condensed Consolidated Balance Sheets.  The Company paid $0.3 million and $0.9 million in quarterly settlement payments pursuant to its hedges during the three- and nine-month periods ended September 30, 2013, respectively, compared to payments of $0.3 million and $1.0 million in the comparable prior year three- and nine-month periods, respectively.  These payments were included in interest expense in the Condensed Consolidated Statements of Operations.

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

(1) The Company had letters of credit totaling $637 issued on the Revolving Facility at both September 30, 2013 and December 31, 2012.

As the Company’s debt bears interest at floating rates, the Company estimates that the carrying values of its debt at September 30, 2013 and December 31, 2012 approximate fair value.

9.              Income Taxes

The Company has estimated that its effective income tax rate for 2013 will be approximately 25.4%.  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.

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 parking lot 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.

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.

11

Revenues from the Company’s Lime and Limestone Operations increased 9.0% in the third quarter 2013, compared to the third quarter 2012, primarily because of increased sales volumes of approximately 8.9% for the Company’s lime and limestone products due to increased demand, principally from its construction and environmental customers, and average product price increases of approximately 0.1% realized for the Company’s lime and limestone products in the third quarter 2013, compared to the third quarter 2012.  For the nine months ended September 30, 2013, revenues from the Company’s Lime and Limestone operations decreased 1.8%, compared to the comparable prior year period, primarily due to decreased sales volumes of approximately 2.6%, principally due to reduced demand from its steel customers due to the reduction in steel output in the United States and from its oil and gas services customers due to reduced oil and gas drilling activity in the Company’s markets, partially offset by increased sales volumes to the Company’s construction and environmental customers. The decreased sales volumes in the first nine months 2013 was partially offset by average product price increases of approximately 0.8% in the first nine months 2013, compared to the comparable 2012 period.  While it is difficult to determine the impact of the recent partial FEDERAL government shutdown in the short term, the Company expects demand for its lime and limestone products from its construction and environmental customers to continue to increase moderately in the fourth quarter 2013, compared to last year’s fourth quarter, while demand from its steel and oil and gas services customers is expected to be flat year over year.

The Company’s gross profit from its Lime and Limestone Operations increased by 20.6% and 0.9% in the third quarter and first nine months 2013, compared to the comparable 2012 periods.  The increased gross profit for the Company’s Lime and Limestone Operations in the third quarter 2013 resulted primarily from the increase in revenues discussed above. The increase in gross profit for the first nine months 2013 resulted primarily from a decrease in outside contractor stripping costs to $1.5 million, compared $2.6 million in the comparable 2012 period, partially offset by the decrease in revenues discussed above.  The timing and amount of contract stripping costs in future periods will depend upon, among other things, the availability and cost-effective utilization of the contractors and their equipment.

Revenues from the Company’s Natural Gas Interests decreased 10.1% in the third quarter 2013, compared to the comparable 2012 quarter, due to lower production volumes (approximately 23.2%) resulting from the normal declines in production rates on the Company’s existing natural gas wells, partially offset by higher prices for the Company’s natural gas (approximately 13.1%).  Revenues from Natural Gas Interests decreased 20.8% in the first nine months 2013, compared to the comparable 2012 period, resulting from lower production volumes (approximately 21.8%), partially offset by higher prices for the Company’s natural gas (approximately 1.0%).  The number of producing wells in 2013 remains at 39 wells.  No new wells were drilled in the first nine months 2013 or are currently being drilled.  The Company cannot predict the number of additional wells that ultimately will be drilled, if any, or their results.

Liquidity and Capital Resources.

Net cash provided by operating activities was $24.2 million in the first nine months 2013, compared to $24.9 million in the comparable 2012 period, a decrease of $0.7 million, or 2.9%.  Net cash provided by operating activities is composed of net income, depreciation, depletion and amortization (“DD&A”), deferred income taxes and other non-cash items included in net income, and changes in working capital.  In the first nine months 2013, cash provided by operating activities was principally composed of $12.2 million net income, $11.0 million DD&A and $1.3 million deferred income taxes, compared to $12.6 million net income, $11.2 million DD&A and $1.9 million deferred income taxes in the first nine months 2012.  The most significant changes in working capital items in the first nine months 2013 were a net increase in trade receivables of $3.2 million and a $1.5 million increase in accounts payable and accrued expenses.  The most significant changes in working capital items in the first nine months 2012 were net increases in inventories and trade receivables of $1.6  million and $0.7 million, respectively.  The net increases in trade receivables in the 2013 and 2012 periods primarily resulted from increases in revenues in the third quarters 2013 and 2012, compared to the fourth quarters 2012 and 2011, respectively.

12

The Company had $6.7 million in capital expenditures in the first nine months 2013, compared to $6.5 million in the comparable period last year.

Net cash used in financing activities was $3.9 million and $44.5 million in the 2013 and 2012 first nine-month periods, respectively, consisting primarily of repayments of $3.8 million of term loan debt in each of the first nine months 2013 and 2012, and $0.2 million and $40.8 million for purchase of treasury shares in the first nine months 2013 and 2012, respectively.  Cash and cash equivalents increased $13.6 million to $43.4 million at September 30, 2013 from $29.8 million at December 31, 2012.

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 September 30, 2013, 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 upon 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 September 30, 2013 and December 31, 2012, resulted in liabilities of $2.0 million and $2.6 million, respectively, which are included in accrued expenses ($1.0 million and $1.1 million, respectively) and other liabilities ($0.8 million and $1.5 million, respectively) on the Company’s Condensed Consolidated Balance Sheets.  The Company paid $0.3 million and $0.9 million in quarterly settlement payments pursuant to its hedges during the three- and nine-month periods ended September 30, 2013, respectively, compared to payments of $0.3 million and $1.0 million in the comparable prior year three- and nine-month periods, respectively.  These payments were included in interest expense in the Condensed Consolidated Statements of Operations.

13

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 September 30, 2013, the Company had no material open orders or commitments that are not included in current liabilities on the September 30, 2013 Condensed Consolidated Balance Sheet.

As of September 30, 2013, the Company had $22.9 million in total debt outstanding and no draws on its $30 million Revolving Facility other than the $0.6 million of letters of credit.  The Company believes that cash on hand, cash generated from operations and funds available under the Revolving Facility will be sufficient to meet the Company’s operating needs, ongoing capital needs and debt service for the next 12 months and liquidity needs for the near future.

Results of Operations.

Revenues in the third quarter 2013 increased to $36.9 million from $34.1 million in the third quarter 2012, an increase of $2.8 million, or 8.2%.  Revenues from the Company’s Lime and Limestone operations in the third quarter 2013 increased $2.9 million, or 9.0%, to $35.5 million from $32.6 million in the comparable 2012 quarter, while revenues from its Natural Gas Interests decreased $157 thousand, or 10.1%, to $1.4 million from $1.6 million in the comparable prior year quarter.  For the nine months ended September 30, 2013, revenues decreased to $103.7 million from $106.7 million in the comparable 2012 period, a decrease of $3.0 million, or 2.8%.  Revenues from the Company’s Lime and Limestone Operations in the first nine months 2013 decreased $1.9 million, or 1.8%, to $99.3 million from $101.2 million in the comparable 2012 period, while revenues from its Natural Gas Interests decreased $1.1 million, or 20.8%, to $4.3 million from $5.5 million in the comparable prior year period.  As discussed above, the increase in Lime and Limestone Operations revenues in the third quarter 2013, compared to last year’s third quarter, resulted primarily from increased sales volumes of the Company’s lime and limestone products, while the decrease in Lime and Limestone Operations revenues in the first nine months 2013, compared to the comparable 2012 period, was caused primarily by the reduced sales volumes.

Production volumes from the Company’s Natural Gas Interests for the third quarter 2013 totaled 239 thousand MCF, sold at an average price of $5.87 per MCF, compared to 303 thousand MCF, sold at an average price of $5.19 per MCF, in the comparable 2012 quarter.  Production volumes for the first nine months 2013 from Natural Gas Interests totaled 751 thousand MCF, sold at an average price of $5.75 per MCF, compared to the first nine months 2012 when 957 thousand MCF was produced and sold at an average price of $5.69 per MCF.  The Company’s average prices per MCF exceeds average natural gas prices because the Company’s natural gas contains liquids.  The Company’s average prices per MCF in the 2013 periods were higher than in the prior year’s comparable periods due to the increases in natural gas prices, partially offset by lower prices for natural gas liquids.

The Company’s gross profit was $9.1 million in the third quarter 2013, compared to $7.8 million in the comparable 2012 quarter, an increase of $1.4 million, or 17.4%. Gross profit in the first nine months 2013 was $24.4 million, a decrease of $950 thousand, or 3.8%, from $25.3 million in the first nine months 2012.

Included in gross profit for the third quarter and first nine months 2013 were $8.4 million and $22.4 million, respectively, from the Company’s Lime and Limestone Operations, compared to $7.0 million and $22.2 million, respectively, in the comparable 2012 periods.  The Company’s gross profit margin as a percent of revenues from its Lime and Limestone Operations increased to 23.7% and 22.6% for the third quarter and first nine months 2013, from 21.4% and 22.0% in the third quarter and first nine months 2012. The increased gross profit and gross profit margin for the Company’s Lime and Limestone Operations in the third quarter 2013 resulted primarily from the increased revenues discussed above.  The increase in gross profit and gross profit margin for the first nine months 2013 resulted primarily from the reduction in outside contractor stripping costs in the 2013 period, partially offset by the decrease in revenues, discussed above.
