Leases [Abstract]

LEASES

(H) LEASES

We lease certain real estate, buildings, and equipment. Certain of these leases contain escalations of rent over the term of the lease, as well as options for us to extend the term of the lease at the end of the original term. These extensions range from periods of 1 to 20 years. Our lease agreements do not contain material residual value guarantees or material restrictive covenants. In calculating the present value of future minimum lease payments, we use the rate implicit in the lease if it can be determined. Otherwise, we use our incremental borrowing rate in effect at the commencement of the lease to determine the present value of the future minimum lease payments. Additionally, we lease certain equipment under short-term leases with initial terms of less than 12 months, which are not recorded on the balance sheet.

Lease expense for our operating and short-term leases is as follows:

INCOME TAXES

Dec. 31, 2023

Income Tax Disclosure [Abstract]

INCOME TAXES

(L) INCOME TAXES

Income Taxes for the interim periods presented have been included in the accompanying financial statements on the basis of an estimated annual effective tax rate. In addition to the amount of tax resulting from applying the estimated annual effective tax rate to pre-tax income, we will include, when appropriate, certain items treated as discrete events to arrive at an estimated overall tax amount. The effective tax rate for the nine months ended December 31, 2023, was approximately 22%, which was consistent with the effective tax rate for the nine months ended December 31, 2022. The effective tax rate was higher than the U.S. Statutory rate of 21% mainly because of state income taxes, partially offset by a benefit recognized related to percentage depletion.

- Definition

The entire disclosure for income taxes. Disclosures may include net deferred tax liability or asset recognized in an enterprise's statement of financial position, net change during the year in the total valuation allowance, approximate tax effect of each type of temporary difference and carryforward that gives rise to a significant portion of deferred tax liabilities and deferred tax assets, utilization of a tax carryback, and tax uncertainties information.

BASIS OF PRESENTATION

(A) BASIS OF PRESENTATION

The accompanying Unaudited Consolidated Financial Statements as of and for the three and nine months ended December 31, 2023, include the accounts of Eagle Materials Inc. and its majority-owned subsidiaries (collectively, the Company, us, or we) and have been prepared by the Company, without audit, pursuant to the rules and regulations of the Securities and Exchange Commission. These Unaudited Consolidated Financial Statements should be read in conjunction with the Audited Consolidated Financial Statements and the notes thereto included in our Annual Report on Form 10-K filed with the Securities and Exchange Commission on May 19, 2023.

Certain information and footnote disclosures normally included in financial statements prepared in accordance with generally accepted accounting principles have been condensed or omitted pursuant to such rules and regulations, although we believe that the disclosures are adequate to make the information presented not misleading. In our opinion, all adjustments (consisting solely of normal recurring adjustments) necessary to present fairly the information in the following unaudited consolidated financial statements of the Company have been included. The results of operations for interim periods are not necessarily indicative of the results for the full year.

The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosures of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates.

There have been no recent accounting pronouncements that are expected to materially affect the Company.

REVENUE

Dec. 31, 2023

Revenue from Contract with Customer [Abstract]

REVENUE

(D) REVENUE

We earn Revenue primarily from the sale of products, which include cement, concrete, aggregates, gypsum wallboard, and recycled paperboard. The vast majority of Revenue from the sale of concrete, aggregates, and gypsum wallboard is originated by purchase orders from our customers, who are mostly third-party contractors and suppliers. Revenue from the sale of cement is recognized at the point-of-sale to customers under sales orders. Revenue from our Recycled Paperboard segment is generated mainly through long-term supply agreements. These agreements do not have a stated maturity date, but may be terminated by either party with a two to three-year notice period. We invoice customers upon shipment, and our collection terms range from 30 to 75 days. Revenue from the sale of cement, concrete, aggregates, and gypsum wallboard not related to long-term supply agreements is recognized upon shipment of the related products to customers, which is when title and ownership are transferred, and the customer is obligated to pay.

Revenue from sales under our long-term supply agreements is also recognized upon transfer of control to the customer, which generally occurs at the time the product is shipped from the production facility or terminal location. Our long-term supply agreements with customers define, among other commitments, the volume of product that we must provide and the volume that the customer must purchase by the end of the defined periods. Pricing structures under our agreements are generally market-based, but are subject to certain contractual adjustments. Shortfall amounts, if applicable under these arrangements, are constrained and not recognized as Revenue until an agreement is reached with the customer and, therefore, are not subject to the risk of reversal.

The Company offers certain of its customers, including those with long-term supply agreements, rebates and incentives, which we treat as variable consideration. We adjust the amount of Revenue recognized for the variable consideration using the most likely amount method based on past history and projected volumes in the rebate and incentive period. Any amounts billed to customers for taxes are excluded from Revenue.

The Company has elected to treat freight and delivery charges we pay for the delivery of goods to our customers as a fulfillment activity rather than a separate performance obligation. When we arrange for a third party to deliver products to customers, fees for shipping and handling billed to the customer are recorded as Revenue, while costs we incur for shipping and handling are recorded as expenses and included in Cost of Goods Sold.

Other Non-Operating Income includes lease and rental income, asset sale income, non-inventoried aggregates sales income, distribution center income, and trucking income, as well as other miscellaneous revenue items and costs that have not been allocated to a business segment.

See Footnote (N) to the Unaudited Consolidated Financial Statements for disaggregation of revenue by segment.

- Definition

The entire disclosure of revenue from contract with customer to transfer good or service and to transfer nonfinancial asset. Includes, but is not limited to, disaggregation of revenue, credit loss recognized from contract with customer, judgment and change in judgment related to contract with customer, and asset recognized from cost incurred to obtain or fulfill contract with customer. Excludes insurance and lease contracts.

Share-Based Payment Arrangement [Abstract]

SHARE-BASED EMPLOYEE COMPENSATION

(I) Share-BASED EMPLOYEE COMPENSATION

On August 3, 2023, our stockholders approved the Eagle Materials Inc. 2023 Equity Incentive Plan (the 2023 Plan), which reserves 1,425,000 shares for future grants of stock awards. Under the terms of the 2023 Plan, we can issue equity awards, including stock options, restricted stock units, restricted stock, and stock appreciation rights, to employees of the Company, members of the Board of Directors, consultants, independent contractors, and agents of the Company. The Compensation Committee of our Board of Directors specifies grant terms for awards under the Plan.

Long-Term Compensation Plans

OPTIONS

In May 2023, under the 2013 Amended and Restated Incentive Plan (the Prior Plan), the Compensation Committee of the Board of Directors approved the granting to certain officers and key employees an aggregate of 2,296 performance-vesting stock options that will be earned only if certain performance conditions are satisfied (the Fiscal 2024 Employee Performance Stock Option Award). The performance criteria for the Fiscal 2024 Employee Performance Stock Option Award are based upon the achievement of certain levels of return on equity (as defined in the option agreements), ranging from 10.0% to 20.0%, for the performance periods described in the table below. All stock options in each performance period will be earned if the return on equity is 20.0% or greater. If the return on equity is less than 20% but at least 10% in any performance period, the amount of stock options earned in such period will be reduced proportionately using straight-line interpolation, such that approximately 66.7% of the amount of stock options granted will be earned if the return on equity is 10.0%. If the Company does not achieve a return on equity of at least 10.0% during any performance period, all stock option awards for that performance period will be forfeited. The stock option performance periods are as follows:


	Options		Performance Period	Vesting Date
One-Year Performance Shares		574	April 1, 2023 to March 31, 2024	May 2024
Two-Year Performance Shares		574	April 1, 2023 to March 31, 2025	May 2025
Three-Year Performance Shares		1,148	April 1, 2023 to March 31, 2026	May 2026

The stock options have a term of 10 years from the grant date. The Compensation Committee also approved the granting of 1,914 time-vesting stock options to the same officers and key employees, which vest ratably over three years (the Fiscal 2024 Employee Time-Vesting Stock Option Award).

In August 2023, under the 2023 Plan, the Compensation Committee granted 1,348 options to members of the Board of Directors (the Fiscal 2024 Board of Directors Stock Option Award). Options granted under the Fiscal 2024 Board of Directors Stock Option Award vest one year after the grant date, and can be exercised from the date of vesting until their expiration on the tenth anniversary of the grant date.

The Fiscal 2024 Employee Performance Stock Option Award, the Fiscal 2024 Employee Time-Vesting Stock Option Award, and the Fiscal 2024 Board of Directors Stock Option Award were valued at their grant date using the Black-Scholes option pricing model. The weighted-average assumptions used in the Black-Scholes model to value the option awards for fiscal 2024 are as follows:



Dividend Yield		0.8	%
Expected Volatility		38.8	%
Risk-Free Interest Rate		3.7	%
Expected Life	6.0 years

In addition to the stock options described above, we issue stock options to certain employees from time to time. Any options issued are valued using the Black-Scholes options pricing model on the grant date and expensed over the vesting period.

Stock option expense for all outstanding stock option awards totaled approximately $0.5 million and $1.5 million for the three and nine months ended December 31, 2023, respectively, and $0.8 million and $2.7 million for the three and nine months ended December 31, 2022, respectively. At December 31, 2023, there was approximately $2.2 million of unrecognized compensation cost related to outstanding stock options, which is expected to be recognized over a weighted-average period of 1.9 years.

The following table represents stock option activity for the nine months ended December 31, 2023:


	Number of Shares			Weighted- Average Exercise Price
Outstanding Options at March 31, 2023		436,949		$	89.69
Granted		5,558		$	172.62
Exercised		(131,099	)	$	88.17
Cancelled		(1,000	)	$	73.37
Outstanding Options at December 31, 2023		310,408		$	91.86
Options Exercisable at December 31, 2023		215,822
Weighted-Average Fair Value of Options Granted During the Year	$	69.84

The following table summarizes information about stock options outstanding at December 31, 2023:


	Options Outstanding						Options Exercisable
Range of Exercise Prices	Number of Shares Outstanding		Weighted- Average Remaining Contractual Life (in years)		Weighted- Average Exercise Price		Number of Shares Outstanding		Weighted- Average Exercise Price
$59.32 - $81.28		113,490		5.91	$	62.49		71,086	$	63.67
$87.37 - $106.24		125,721		4.60	$	95.77		122,005	$	95.72
$118.27 - $166.75		71,197		8.34	$	131.77		22,731	$	130.79
		310,408		5.94	$	91.86		215,822	$	88.86

At December 31, 2023, the aggregate intrinsic value of the outstanding and exercisable options was approximately $34.4 million and $24.6 million, respectively. The total intrinsic value of options exercised during the nine months ended December 31, 2023, was approximately $10.6 million.

RESTRICTED STOCK

In May 2023, under the Prior Plan, the Compensation Committee approved the granting to certain officers and key employees an aggregate of 45,693 shares of performance-vesting restricted stock that will be earned if certain performance conditions are satisfied (the Fiscal 2024 Employee Restricted Stock Performance Award). The performance criteria for the Fiscal 2024 Employee Restricted Stock Performance Award are based upon the

achievement of certain levels of return on equity (as defined in the award agreement), ranging from 10.0% to 20.0%, for the performance periods described in the table below. All restricted shares in each performance period will be earned if the return on equity is 20.0% or greater. If the return on equity is less than 20% but at least 10% in any performance period, the amount of shares earned in such period will be reduced proportionately using straight-line interpolation, such that approximately 66.7% of the amount of shares issued will be earned if the return on equity is 10.0%. If the Company does not achieve a return on equity of at least 10.0% during any performance period, all awards for that performance period will be forfeited. The restricted share performance periods are as follows:


	Shares		Performance Period	Vesting Date
One-Year Performance Shares		11,424	April 1, 2023 to March 31, 2024	May 2024
Two-Year Performance Shares		11,424	April 1, 2023 to March 31, 2025	May 2025
Three-Year Performance Shares		22,845	April 1, 2023 to March 31, 2026	May 2026

The Compensation Committee also approved the granting of 38,072 shares of time-vesting restricted stock to the same officers and key employees, which vest ratably over three years (the Fiscal 2024 Employee Restricted Stock Time-Vesting Award). The Fiscal 2024 Employee Restricted Stock Performance Award and the Fiscal 2024 Employee Restricted Stock Time-Vesting Award were valued at the closing price of the stock on the grant date and are being expensed over a three-year period.

In August 2023, under the 2023 Plan, we granted 10,755 shares of restricted stock to members of the Board of Directors (the Fiscal 2024 Board of Directors Restricted Stock Award). Restrictions on these shares will lapse one year after the grant date. The Fiscal 2024 Board of Directors Restricted Stock Award was valued at the closing price of the stock on the grant date, and is being expensed over a one-year period.

In addition to the restricted stock described above, from time to time we issue restricted stock to certain employees. These awards are valued at the closing price of the stock on the grant date and expensed over the vesting period.

The fair value of restricted stock is based on the stock price on the grant date. The following table summarizes the activity for nonvested restricted shares during the nine months ended December 31, 2023:


	Number of Shares			Weighted-Average Grant Date Fair Value
Nonvested Restricted Stock at March 31, 2023		219,084		$	96.54
Granted		97,257		$	169.62
Vested		(35,958	)	$	146.24
Forfeited		(3,000	)	$	139.03
Nonvested Restricted Stock at December 31, 2023		277,383		$	125.10

Expense related to restricted shares was approximately $4.0 million and $13.8 million for the three and nine months ended December 31, 2023, respectively, and $3.3 million and $11.0 million for the three and nine months ended December 31, 2022, respectively. At December 31, 2023, there was approximately $21.5 million of unearned compensation from restricted stock, which will be recognized over a weighted-average period of 1.7 years.

The number of shares available for future grants of stock options, restricted stock units, stock appreciation rights, and restricted stock under the 2023 Plan was 1,411,804 at December 31, 2023.

Revolving Credit Facility

We have an unsecured $750.0 million revolving credit facility (the Revolving Credit Facility). The Revolving Credit Facility includes a separate $200.0 million term loan facility (the Term Loan) and also provides the Company the option to increase the borrowing capacity by up to $375.0 million (for a total borrowing capacity of $1,125.0

million), provided the existing lenders, or new lenders, agree to such increase. The Revolving Credit Facility includes a $40.0 million letter of credit facility and a swingline loan sub-facility of $25.0 million, and expires on May 5, 2027.

The Revolving Credit Facility contains customary covenants for an unsecured investment-grade facility, including covenants that restrict the Company’s and/or its subsidiaries’ ability to incur additional debt; encumber assets; merge with or transfer or sell assets to other persons; and enter into certain affiliate transactions. The Revolving Credit Facility also requires the Company to maintain at the end of each fiscal quarter a Leverage Ratio of 3.50:1.00 or less and an Interest Coverage Ratio (both ratios, as defined in the Revolving Credit Facility) equal to or greater than 2.50 to 1.00 (collectively, the Financial Covenants).

At the Company’s option, outstanding loans under the Revolving Credit Facility bear interest, at a variable rate equal to either (i) the adjusted term SOFR rate (secured overnight financing rate), plus 10 basis points, plus an agreed spread (ranging from 100 to 162.5 basis points, which is established based on the Company's credit rating); (ii) in respect of any Revolving Loans (until such time as the then-existing Benchmark (as defined in the Revolving Credit Facility) is replaced in accordance with the Revolving Credit Facility), the adjusted daily simple SOFR rate, plus 10 basis points, plus an agreed spread (ranging from 100 to 162.5 basis points, which is established based on the Company's credit rating) or (iii) an Alternate Base Rate (as defined in the Revolving Credit Facility), which is the highest of (a) the Prime Rate (as defined in the Revolving Credit Facility) in effect on any applicable day, (b) the NYFRB Rate (as defined in the Revolving Credit Facility) in effect on any applicable day, plus ½ of 1%, and (c) the Adjusted Term SOFR (as defined in the Revolving Credit Facility) for a one month interest period on any applicable day, or if such day is not a business day, the immediately preceding business day, plus 1.0%, in each case plus an agreed upon spread (ranging from 0 to 62.5 basis points), which is established quarterly based on the Company's credit rating. The Company is also required to pay a facility fee on unused available borrowings under the Revolving Credit Facility ranging from 9 to 22.5 basis points, which is established based on the Company's then credit rating.

The Company pays each lender a participation fee with respect to such lender’s participations in letters of credit, which fee accrues at the same Applicable Rate (as defined in the Revolving Credit Facility) used to determine the interest rate applicable to Eurodollar Revolving Loans (as defined in the Revolving Credit Facility), plus a fronting fee for each letter of credit issued by the issuing bank in an amount equal to 12.5 basis points per annum on the daily maximum amount then available to be drawn under such letter of credit. The Company also pays each issuing bank such bank’s standard fees with respect to issuance, amendment or extensions of letters of credit and other processing fees, and other standard costs and charges relating to such issuing bank’s letters of credit from time to time.

There were $107.0 million of outstanding borrowings under the Revolving Credit Facility, plus $8.3 million outstanding letters of credit as of December 31, 2023, resulting in $634.7 million of available borrowings under the Revolving Credit Facility, net of the outstanding letters of credit. We were in compliance with all Financial Covenants on December 31, 2023; therefore, the entire $634.7 million is available for future borrowings.

Term Loan

On May 5, 2022, we borrowed the $200.0 million Term Loan under the Revolving Credit Facility, and used these proceeds to, among other things, pay down a portion of the Revolving Credit Facility. The Term Loan requires quarterly principal payments of $2.5 million, with any unpaid amounts due upon maturity on May 5, 2027. At the Company’s option, principal amounts outstanding under the Term Loan bear interest as set forth in the Revolving Credit Facility (but not, for the avoidance of doubt, at a daily simple SOFR rate unless and until such time as the then-existing Benchmark (as defined in the Revolving Credit Facility) is replaced in accordance with the Revolving Credit Facility).

2.500% Senior Unsecured Notes Due 2031

On July 1, 2021, we issued $750.0 million aggregate principal amount of 2.500% senior notes due July 2031 (the 2.500% Senior Unsecured Notes). The 2.500% Senior Unsecured Notes are senior unsecured obligations of the Company and are not guaranteed by any of our subsidiaries. The 2.500% Senior Unsecured Notes were issued net of original issue discount of $6.3 million and have an effective interest rate of approximately 2.6%. The original issue discount is being amortized by the effective interest method over the 10-year term of the notes. The 2.500% Senior Unsecured Notes are redeemable prior to April 1, 2031, at a redemption price equal to 100% of the aggregate principal amount of the 2.500% Senior Unsecured Notes being redeemed, plus the present value of remaining scheduled payments of principal and interest from the applicable redemption date to April 1, 2031, discounted to the redemption date on a semi-annual basis at the Treasury rate plus 20 basis points. The 2.500% Senior Unsecured Notes are redeemable on or after April 1, 2031, at a redemption price equal to 100% of the aggregate principal amount of the 2.500% Senior Unsecured Notes being redeemed, plus accrued and unpaid interest to, but excluding, the applicable redemption date. If we experience certain change of control triggering events, we would be required to offer to repurchase the 2.500% Senior Unsecured Notes at a purchase price equal to 101% of the aggregate principal amount of the 2.500% Senior Unsecured Notes being repurchased, plus accrued and unpaid interest to, but excluding, the applicable redemption date. The indenture governing the 2.500% Senior Unsecured Notes contains certain covenants that limit our ability to create or permit to exist certain liens; enter into sale and leaseback transactions; and consolidate, merge, or transfer all or substantially all of our assets, and provides for certain events of default that, if any occurred, would permit or require the principal of and accrued interest on the 2.500% Senior Unsecured Notes to become or be declared due and payable.

Segment Reporting [Abstract]

SEGMENT INFORMATION

(N) SEGMENT INFORMATION

Operating segments are defined as components of an enterprise that engage in business activities that earn revenue, incur expenses, and prepare separate financial information that is evaluated regularly by our chief operating decision maker in order to allocate resources and assess performance.

Our business is organized into two sectors within which there are four reportable business segments. The Heavy Materials sector includes the Cement and Concrete and Aggregates segments. The Light Materials sector includes the Gypsum Wallboard and Recycled Paperboard segments.

Our primary products are commodities that are essential in commercial and residential construction; public construction projects; and projects to build, expand, and repair roads and highways. Demand for our products is generally cyclical and seasonal, depending on economic and geographic conditions. We distribute our products throughout most of the United States, except the Northeast, which provides us with regional economic diversification. Our operations are conducted in the U.S. and include the mining of limestone for the manufacture, production, distribution, and sale of portland cement, including portland limestone cement (a basic construction material that is the essential binding ingredient in concrete); the grinding and sale of slag; the mining of gypsum for the manufacture and sale of gypsum wallboard; the manufacture and sale of recycled paperboard to the gypsum wallboard industry and other paperboard converters; the sale of readymix concrete; and the mining and sale of aggregates (crushed stone, sand, and gravel).

We operate eight modern cement plants (one of which is operated through a joint venture located in Buda, Texas), one slag grinding facility, and over 30 cement distribution terminals. Our cement companies focus on the U.S. heartland and operate as an integrated network selling product primarily in California, Colorado, Illinois, Indiana, Iowa, Kansas, Kentucky, Missouri, Nebraska, Nevada, Ohio, Oklahoma, Tennessee, and Texas. We operate over 25 readymix concrete batch plants and five aggregates processing plants in markets that are complementary to our cement network.

We operate five gypsum wallboard plants and a recycled paperboard mill. We distribute gypsum wallboard and recycled paperboard throughout the continental U.S., with the exception of the Northeast.

We account for intersegment sales at market prices. For segment reporting purposes only, we proportionately consolidate our 50% share of the Joint Venture Revenue and Operating Earnings, consistent with the way management reports the segments within the Company for making operating decisions and assessing performance.

Segment Operating Earnings, including the proportionately consolidated 50% interest in the revenue and expenses of the Joint Venture, represent Revenue, less direct operating expenses, segment Depreciation, and segment Selling, General, and Administrative expenses. We account for intersegment sales at market prices. Corporate assets consist mainly of cash and cash equivalents, general office assets, and miscellaneous other assets.

The basis used to disclose Identifiable Assets; Capital Expenditures; and Depreciation, Depletion, and Amortization conforms with the equity method, and is similar to how we disclose these accounts in our Unaudited Consolidated Balance Sheets and Unaudited Consolidated Statements of Earnings.

The segment breakdown of Goodwill is as follows:


	December 31,		March 31,
	2023		2023
	(dollars in thousands)
Cement	$	227,669	$	215,781
Concrete and Aggregates		40,774		40,774
Gypsum Wallboard		116,618		116,618
Recycled Paperboard		7,538		7,538
	$	392,599	$	380,711

The increase in Goodwill in the Cement segment is related to the Stockton Terminal Acquisition. The purchase price allocation is still in progress, and may affect the recorded balance of Goodwill when completed.

Commitments and Contingencies Disclosure [Abstract]

COMMITMENTS AND CONTINGENCIES

(P) COMMITMENTS AND CONTINGENCIES

We have certain deductible limits under our workers’ compensation and liability insurance policies for which reserves are established based on the undiscounted estimated costs of known and anticipated claims. We have entered into standby letter of credit agreements relating to workers’ compensation, auto, and general liability self-insurance. At December 31, 2023, we had contingent liabilities under these outstanding letters of credit of approximately $8.3 million.

In the ordinary course of business, we execute contracts involving indemnifications that are both standard in the industry and specific to a transaction, such as the sale of a business. These indemnifications may include claims relating to any of the following: environmental and tax matters; intellectual property rights; governmental regulations and employment-related matters; customer, supplier, and other commercial contractual relationships; and construction contracts and financial matters. While the maximum amount to which the Company may be exposed under such agreements cannot be estimated, management believes these indemnifications will not have a material adverse effect on our consolidated financial position, results of operations, or cash flows. We currently have no outstanding guarantees.

We are currently contingently liable for performance under $29.3 million in performance bonds required by certain states and municipalities, and their related agencies. The bonds are principally for certain reclamation obligations and mining permits. We have indemnified the underwriting insurance company against any exposure under the performance bonds. In our experience, no material claims have been made against these financial instruments.

Retirement Benefits [Abstract]

PENSION AND EMPLOYEE BENEFIT PLANS

(K) PENSION AND EMPLOYEE BENEFIT PLANS

We sponsor several single-employer defined benefit plans and defined contribution plans, which together cover substantially all our employees. Benefits paid under the single-employer defined benefit plans covering certain hourly employees were historically based on years of service and the employee’s qualifying compensation over the last few years of employment. Over the last several years, these plans have been frozen to new participants and new benefits, with the last plan becoming frozen during fiscal 2020. Our defined benefit plans are all fully funded, with plan assets exceeding the benefit obligation at March 31, 2023. Due to the frozen status and current funding of the single-employer pension plans, our expected pension expense for fiscal 2024 is less than $0.2 million.
