MUELLER WATER PRODUCTS, INC. AND SUBSIDIARIES

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

Note 1. Organization

Mueller Water Products, Inc., a Delaware corporation, together with its consolidated subsidiaries, operates in two business segments: Mueller Co. and Anvil. Mueller Co. manufactures valves for water and gas systems, including butterfly, iron gate, tapping, check, plug and ball valves, as well as dry-barrel and wet-barrel fire hydrants and a broad range of metering, leak detection and pipe condition assessment products for the water infrastructure industry. Anvil manufactures and sources a broad range of products, including a variety of fittings, couplings, hangers and related products. The “Company,” “we,” “us” or “our” refer to Mueller Water Products, Inc. and its subsidiaries or their management. With regard to the Company's segments, “we,” “us” or “our” may also refer to the segment being discussed or its management.

On April 1, 2012, we sold the businesses comprising our former U.S. Pipe segment to USP Holdings Inc., an affiliate of Wynnchurch Capital, Ltd (“Wynnchurch”). U.S. Pipe's results of operations have been reclassified as discontinued operations, and its assets and liabilities reclassified as held for sale, for all prior periods.

Our consolidated financial statements are prepared in conformity with accounting principles generally accepted in the United States of America ("GAAP"), which require us to make certain estimates and assumptions that affect the reported amounts of assets, liabilities, sales and expenses and the disclosure of contingent assets and liabilities for the reporting periods. Actual results could differ from those estimates. All significant intercompany balances and transactions have been eliminated. In our opinion, all normal and recurring adjustments that we consider necessary for a fair financial statement presentation have been made. Certain reclassifications have been made to previously reported amounts to conform to the current presentation. The condensed consolidated balance sheet data at September 30, 2012 was derived from audited financial statements, but does not include all disclosures required by GAAP.

Unless the context indicates otherwise, whenever we refer to a particular year, we mean the fiscal year ended or ending September 30 in that particular calendar year.

Note 2. Discontinued Operations

On April 1, 2012, we sold our former U.S. Pipe segment and received proceeds of $94.0 million in cash, subject to adjustments, and the agreement by the purchaser to reimburse us for expenditures to settle certain previously-existing liabilities estimated at $10.1 million at March 31, 2012. During the quarter ended December 31, 2012, we received $4.5 million in cash for certain purchase price adjustments and reduced our loss on sale of discontinued operations accordingly. Additional purchase price adjustments related to closing date balances, which would increase the purchase price by $1.0 million if resolved in our favor, remain in dispute.

The table below represents a summary of the operating results for the U.S. Pipe discontinued operations.

Note 3. Income Taxes

After including the tax effect of the loss on the sale of U.S. Pipe, our U.S. deferred tax liabilities are insufficient to fully support our U.S. deferred tax assets, which include net operating loss carryforwards.  Accordingly, we initially recorded income tax expense to establish valuation allowances related to our overall deferred tax assets during the quarter ended March 31, 2012.

We reevaluate the need for a valuation allowance against the U.S. deferred tax assets each quarter, considering results to date, projections of taxable income, tax planning strategies and reversing taxable temporary differences. During the quarter ended December 31, 2012, we decreased our U.S. deferred tax valuation allowance by $4.6 million, including $0.8 million included in other comprehensive income. Notwithstanding the valuation allowance, our net operating loss carryforwards remain available to offset future taxable earnings.

The components of income tax benefit on continuing operations are provided below.

	$	(1.6	)	$	(3.2	)

At December 31, 2012 and September 30, 2012, the gross liabilities for unrecognized income tax benefits were $4.3 million and $4.3 million, respectively.

We recognize interest related to uncertain income tax positions as interest expense and would recognize any penalties that may be incurred as selling, general and administrative expense. At December 31, 2012 and September 30, 2012, we had $0.9 million and $0.9 million, respectively, of accrued interest expense related to uncertain tax positions.

Generally, our state income tax returns are closed for years prior to 2006, except to the extent of our state net operating loss carryforwards, and our Canadian income tax returns are closed for years prior to 2005. During 2012, we concluded an audit by the Internal Revenue Service (the "IRS") for the years 2007 through 2010 with no adverse changes. We are also under audit by several states at various levels of completion. We do not have any material unpaid assessments.

ABL Agreement. On December 18, 2012, we entered into a first amendment to our asset based lending agreement dated August 26, 2010 (the “ABL Agreement”). This amendment, among other things, provides for the following:

• a reduction of $50.0 million in the size of the revolving credit facility to $225.0 million;

•a 100 basis point per annum reduction in the interest rate margins;

• a reduction in the commitment fee to either 0.375% per annum or 0.25% per annum, based on daily average availability during the previous calendar quarter, from 0.50% per annum;

• the extension of the maturity date to the earlier of (1) December 18, 2017 and (2) 60 days prior to the final maturity of our 7.375% Senior Subordinated Notes;

• additional flexibility for us to incur debt, make investments (including acquisitions), dispose of assets and make restricted payments (whether as dividends or junior debt repayments); and

•a reduction in the springing consolidated fixed charge coverage ratio to 1.0:1.0 from 1.1:1.0.

The ABL Agreement also permits us to increase the size of the credit facility by an additional $150 million in certain circumstances subject to adequate borrowing base availability. We may borrow up to $25 million through swing line loans and may have up to $60 million of letters of credit outstanding.

Borrowings under the ABL Agreement bear interest at a floating rate equal to LIBOR plus a margin ranging from 175 to 225 basis points, or a base rate, as defined in the ABL Agreement, plus a margin ranging from 75 to 125 basis points. At December 31, 2012, the applicable LIBOR-based margin was 200 basis points.

Our obligations under the ABL Agreement are secured by a first-priority perfected lien on all of our U.S. receivables and inventory, certain cash and other supporting obligations. Borrowings are not subject to any financial maintenance covenants unless excess availability is less than the greater of $22.5 million and 10% of the aggregate commitments under the ABL Agreement. Excess availability based on December 31, 2012 data, as reduced by outstanding letters of credit and accrued fees and expenses of $34.6 million, was $122.1 million.

8.75%Senior Unsecured Notes. The 8.75% Senior Unsecured Notes (the “Senior Unsecured Notes”) mature in September 2020 and bear interest at 8.75%, paid semi-annually. Based on quoted market prices, the outstanding Senior Unsecured Notes had a fair value of $230.9 million at December 31, 2012.

On January 23, 2013, we delivered notice to redeem $22.5 million aggregate principal amount on February 22, 2013 at a redemption price of 103% plus accrued and unpaid interest. This amount is included in current portion of long-term debt at December 31, 2012.

We may also redeem up to $33.8 million of the Senior Unsecured Notes at a redemption price of 108.75%, plus accrued and unpaid interest, with the net cash proceeds from certain equity offerings prior to September 2013. After August 2015, we may redeem the Senior Unsecured Notes at specified redemption prices plus accrued and unpaid interest. Upon a Change of Control (as defined in the indenture securing the Senior Unsecured Notes), we are required to offer to purchase the outstanding Senior Unsecured Notes at a purchase price of 101% plus accrued and unpaid interest. The Senior Unsecured Notes are subordinate to borrowings under the ABL Agreement.

The indenture securing the Senior Unsecured Notes contains customary covenants and events of default, including covenants that limit our ability to incur debt, pay dividends and make investments. Substantially all of our U.S. subsidiaries guarantee the Senior Unsecured Notes. We believe we were compliant with these covenants at December 31, 2012 and expect to remain in compliance through December 31, 2013.

7.375%Senior Subordinated Notes. The 7.375% Senior Subordinated Notes (the “Senior Subordinated Notes”) mature in June 2017 and bear interest at 7.375%, paid semi-annually. Based on quoted market prices, the outstanding Senior Subordinated Notes had a fair value of $433.7 million at December 31, 2012.

We may redeem any portion of the Senior Subordinated Notes at specified redemption prices plus accrued and unpaid interest, subject to restrictions in the Senior Unsecured Notes. Upon a Change of Control (as defined in the indenture securing the Senior Subordinated Notes), we are required to offer to purchase the outstanding Senior Subordinated Notes at a purchase price of 101%, plus accrued and unpaid interest. The Senior Subordinated Notes are subordinate to borrowings under the ABL Agreement and the Senior Unsecured Notes.

The indenture securing the Senior Subordinated Notes contains customary covenants and events of default, including covenants that limit our ability to incur debt, pay dividends and make investments. Substantially all of our U.S. subsidiaries

guarantee the Senior Subordinated Notes. We believe we were compliant with these covenants at December 31, 2012 and expect to remain in compliance through December 31, 2013.

Note 5. Derivative Financial Instruments

Our ongoing business operations expose us to commodity price risk and interest rate risk that we have previously managed to some extent using derivative instruments. We have used natural gas swap contracts to manage the price risk associated with purchases of natural gas used in certain of our manufacturing processes and interest rate swap contracts to manage interest rate risk associated with our variable-rate borrowings. During 2010, we terminated all of our remaining interest rate swap contracts and no new interest rate swap contracts have been initiated. During 2012, we terminated our remaining natural gas swap contract.

We had designated our natural gas swap contracts and interest rate swap contracts as cash flow hedges of our purchases of natural gas and our interest payments, respectively. As a result, to the extent the hedges were effective, the changes in the fair value of these contracts prior to settlement were reported as a component of other comprehensive income (loss) and reclassified into earnings in the periods during which the hedged transactions affected earnings. Gains and losses on those contracts representing either hedge ineffectiveness or hedge components excluded from the assessment of effectiveness were recognized in earnings as they occurred.

Our derivative contracts were recorded at fair value using publicly observable data such as market natural gas prices and market interest rates. We did not have any derivative contracts outstanding at December 31, 2012 or September 30, 2012.

In the quarter endedDecember 31,2011, we reclassified $1.4 million related to previously terminated interest rate swap contracts to interest expense from accumulated other comprehensive loss.

Note 6. Retirement Plans

The components of net periodic benefit cost allocated to continuing operations for defined benefit pension plans are as follows.

	Three months ended
	December 31,
	2012			2011
	(in millions)
Service cost	$	0.5		$	0.3
Interest cost	1.6			2.6

Amortization of prior service cost	—			0.1
Amortization of actuarial net loss	0.7			0.8
Net periodic benefit cost	$	0.7		$	0.9

The amortization of unrecognized prior service cost and of actuarial losses, net of tax, are recorded as components of other comprehensive income (loss).

Our U.S. pension plan was 103% funded at January 1, 2012 under the provisions of the Pension Protection Act. This reflects the revised governmental guidance of Moving Ahead for Progress in the 21st Century (“MAP-21”). As a result of the MAP-21 changes, we do not expect to make any contributions to our U.S. pension plan during 2013. For financial reporting purposes, our pension plan obligations were 86% funded at September 30, 2012.

On April 1, 2012, we changed certain provisions of our pension and postretirement benefit plans affecting U.S. Pipe participants in these plans. These changes vested all accumulated pension benefits and then froze the plan such that no additional pension benefits would accumulate. Postretirement medical benefits substantially ceased on December 31, 2012. During the three months ended December 31, 2012, we recorded a benefit of $7.4 million, which is included in income from discontinued operations, related to this cessation of benefits.

Note 7. Stock-based Compensation Plans

During the quarter ended December 31, 2012, we granted cash-settled and stock-settled performance shares under our Amended and Restated 2006 Mueller Water Products, Inc. Stock Incentive Plan (the "2006 Stock Plan"). The performance shares are part of multi-year award cycles consisting of annual performance periods coinciding with our fiscal years, with performance goals established within 90 days of the beginning of each performance period by the Compensation and Human Resources Committee of our board of directors. Performance shares do not convey voting rights or earn dividends. Performance shares vest on the last day of the award cycle, unless vested sooner due to change-of-control, death, disability or retirement after accumulation of the required number of points, which are a function of age and years of service, provided that the participant continues to be employed by us through that date. We will distribute the related cash and common stock within 90 days of the end of the award cycle.

A cash-settled performance share entitles the recipient to a cash payment determined at the end of each of two annual performance periods. The amount of cash to be distributed equals the product of the number of performance shares granted multiplied by a performance factor ranging from 0.0 to 2.0 and by the closing price of our common stock on the last day of the award cycle. Compensation expense for cash-settled performance shares is charged against income over the applicable performance period based on the estimated performance factor and the closing price per share of our common stock at each balance sheet date. Outstanding cash-settled performance shares had a fair value of $5.61 per share and a total fair value of $2.1 million at December 31, 2012.

10

A stock-settled performance share entitles the recipient to receive a number of shares of our common stock determined at the end of each of three performance periods. The number of shares of our common stock issuable equals the number of performance shares granted multiplied by a performance factor that ranges from 0.0 to 2.0. Compensation expense for stock-settled performance shares is charged against income over the applicable performance period based on the estimated performance factor and the grant-date price of our common stock.

During the quarter ended December 31, 2011, the Company adopted the Mueller Water Products, Inc. Phantom Plan (the "Phantom Plan"). Phantom Plan awards entitle a recipient to a per-award cash payment equal to the closing price per share of our common stock on the vesting date. Awards generally vest in thirds on successive anniversaries of the grant date. Compensation expense for Phantom Plan awards is charged against income over the vesting period, based on the closing stock price at each balance sheet date until vested. Outstanding Phantom Plan awards had a fair value of $5.61 per award and a total fair value of $3.5 million at December 31, 2012.

We recorded stock-based compensation expense of $2.3 million during the three months endedDecember 31, 2012, and $1.4 million during the three months endedDecember 31, 2011. At December 31, 2012, there was approximately $8.4 million of unrecognized compensation expense related to stock-based awards.

Because the effect of including normally dilutive securities in the earnings per share calculation is antidilutive in loss periods, we exclude all stock-based compensation instruments from the calculations of diluted earnings per share in such periods. Accordingly, we excluded 0.8 million of such instruments from the calculation of diluted earnings per share for the three months endedDecember 31, 2011.

We granted stock-based compensation awards under the 2006 Stock Plan, Mueller Water Products, Inc. 2006 Employee Stock Purchase Plan and Phantom Plan during the three months endedDecember 31, 2012 as follows.    

	Number granted	Weighted average grant date fair value per instrument		Total grant date fair value (in millions)

Note 10.Commitments and Contingencies

We are involved in various legal proceedings that have arisen in the normal course of operations, including the proceedings summarized below. The effect of the outcome of these matters on our financial statements cannot be predicted with certainty as any such effect depends on the amount and timing of the resolution of such matters. Other than the litigation described below, we do not believe that any of our outstanding litigation would have a material adverse effect on our business or prospects.

Environmental. We are subject to a wide variety of laws and regulations concerning the protection of the environment, both with respect to the operations at many of our properties and with respect to remediating environmental conditions that may exist at our own or other properties. We strive to comply with federal, state and local environmental laws and regulations. We accrue for environmental expenses resulting from existing conditions that relate to past operations when the costs are probable and reasonably estimable.

In the acquisition agreement pursuant to which a predecessor to Tyco sold our Mueller Co. and Anvil businesses to the prior owners of these businesses in August 1999, Tyco agreed to indemnify us and our affiliates, among other things, for all “Excluded Liabilities.” Excluded Liabilities include, among other things, substantially all liabilities relating to the time prior to August 1999, including environmental liabilities. The indemnity survives indefinitely. Tyco's indemnity does not cover liabilities to the extent caused by us or the operation of our businesses after August 1999, nor does it cover liabilities arising with respect to businesses or sites acquired after August 1999. Since 2007, Tyco has engaged in multiple corporate restructurings, split-offs and divestitures. While none of these transactions directly affects the indemnification obligations of

13

the Tyco indemnitors under the 1999 acquisition agreement, the result of such transactions is that the assets of, and control over, such Tyco indemnitors has changed. Should any of these Tyco indemnitors become financially unable or fail to comply with the terms of the indemnity, we may be responsible for such obligations or liabilities.

In September 1987, we implemented an Administrative Consent Order (“ACO”) for our Burlington, New Jersey property, which was required under the New Jersey Environmental Cleanup Responsibility Act (now known as the Industrial Site Recovery Act). The ACO required soil and ground-water cleanup, and we completed, and received final approval on, the soil cleanup required by the ACO. We retained this property related to the sale of our former U.S. Pipe segment. We expect ground-water issues as well as issues associated with the demolition of former manufacturing facilities at this site will continue and remediation by us could be required. Long-term ground-water monitoring may also be required, but we do not know how long such monitoring would be required and do not believe monitoring or further remediation costs, if any, will have a material adverse effect on any of our financial statements.

On July 13, 2010, Rohcan Investments Limited (“Rohcan”), the former owner of property leased by Mueller Canada Ltd. and located in Milton, Ontario, filed suit against Mueller Canada Ltd. and its directors seeking C$10.0 million in damages arising from the defendants' alleged environmental contamination of the property and breach of lease. Mueller Canada Ltd. leased the property from 1988 through 2008. We are pursuing indemnification from a former owner for certain potential liabilities that are alleged in this lawsuit, and we have accrued for other liabilities not covered by indemnification.  On December 7, 2011, the Court denied the plaintiff's motion for summary judgment.

Walter Energy-related Income Taxes. Each member of a consolidated group for federal income tax purposes is severally liable for the federal income tax liability of each other member of the consolidated group for any year in which it is a member of the group at any time during such year. Each member of the Walter Energy consolidated group, which included us through December 14, 2006, is also jointly and severally liable for pension and benefit funding and termination liabilities of other group members, as well as certain benefit plan taxes. Accordingly, we could be liable under such provisions in the event any such liability is incurred, and not discharged, by any other member of the Walter Energy consolidated group for any period during which we were included in the Walter Energy consolidated group.

A dispute exists with regard to federal income taxes for 1980 through 1994 allegedly owed by the Walter Energy consolidated group. According to Walter Energy's last available public filing on the matter, Walter Energy's management estimated that the amount of tax claimed by the IRS was approximately $34.0 million for issues currently in dispute in bankruptcy court for matters unrelated to us. This amount is subject to interest and penalties. Of the $34.0 million in claimed tax, $21.0 million represents issues in which the IRS is not challenging the deductibility of the particular expense but only whether such expense is deductible in a particular year. Walter Energy's management believes that Walter Energy's financial exposure should be limited to interest and possible penalties and the amount of any tax claimed will be offset by favorable adjustments in other years.

In addition, the IRS previously issued a Notice of Proposed Deficiency assessing additional tax of $82.2 million for the fiscal years ended May 31, 2000 through December 31, 2005. Walter Energy filed a formal protest with the IRS, but had not reached a final resolution with the Appeals Division at December 31, 2012. The unresolved issues relate primarily to Walter Energy's method of recognizing revenue on the sale of homes and related interest on the installment notes receivable. The items at issue relate primarily to the timing of revenue recognition and consequently, should the IRS prevail on its positions, Walter Energy's financial exposure should be limited to interest and penalties. As a matter of law, we are jointly and severally liable for any final tax determination for any year in which any of our subsidiaries were members of the Walter Energy consolidated group, which means that we would be liable in the event Walter Energy is unable to pay any amounts owed. Walter Energy has disclosed that it believes its filing positions have substantial merit and that it intends to defend vigorously any claims asserted.

Walter Energy effectively controlled all of our tax decisions for periods during which we were a member of the Walter Energy consolidated group for federal income tax purposes and certain combined, consolidated or unitary state and local income tax groups. Under the terms of the income tax allocation agreement between us and Walter Energy dated May 26, 2006, we generally compute our tax liability on a stand-alone basis, but Walter Energy has sole authority to respond to and conduct all tax proceedings (including tax audits) relating to our federal income and combined state returns, to file all such returns on our behalf and to determine the amount of our liability to (or entitlement to payment from) Walter Energy for such previous periods. This arrangement may result in conflicts between Walter Energy and us.

Our separation from Walter Energy on December 14, 2006 was intended to qualify as a tax-free spin-off under Section 355 of the Internal Revenue Code. In addition, the tax allocation agreement provides that if the spin-off is determined not to be tax-free pursuant to Section 355, we generally will be responsible for any taxes incurred by Walter Energy or its shareholders if such taxes result from certain of our actions or omissions and for a percentage of any such taxes that are not a result of our

14

actions or omissions or Walter Energy's actions or omissions or taxes based upon our market value relative to Walter Energy's market value. Additionally, to the extent that Walter Energy was unable to pay taxes, if any, attributable to the spin-off and for which it is responsible under the tax allocation agreement, we could be liable for those taxes as a result of being a member of the Walter Energy consolidated group for the year in which the spin-off occurred.

In accordance with the income tax allocation agreement, Walter Energy used certain tax assets of one of our predecessors in its calendar 2006 tax return for which payment to us is required. The income tax allocation agreement only requires Walter Energy to make the payment upon realization of the tax benefit by receiving a refund or otherwise offsetting taxes due. Walter Energy currently owes us $11.6 million, which includes recent tax audit and amended tax return adjustments, that is payable pending completion of an IRS audit of Walter Energy's 2006 tax year and the related refund of tax from that year. This receivable is included in other current assets at December 31, 2012.

Indemnifications. We are a party to contracts in which it is common for us to agree to indemnify third parties for certain liabilities that arise out of or relate to the subject matter of the contract. In some cases, this indemnity extends to related liabilities arising from the negligence of the indemnified parties, but usually excludes any liabilities caused by gross negligence or willful misconduct. We cannot estimate the potential amount of future payments under these indemnities until events arise that would trigger a liability under the indemnities.

Additionally, in connection with the sale of assets and the divestiture of businesses, such as the divestiture of our U.S. Pipe segment, we may agree to indemnify buyers and related parties for certain losses or liabilities incurred by these parties with respect to: (i) the representations and warranties made by us to these parties in connection with the sale and (ii) liabilities related to the pre-closing operations of the assets or business sold. Indemnities related to pre-closing operations generally include certain environmental and tax liabilities and other liabilities not assumed by these parties in the transaction.

Indemnities related to the pre-closing operations of sold assets or businesses normally do not represent additional liabilities to us, but simply serve to protect these parties from potential liability associated with our obligations existing at the time of the sale. As with any liability, we have accrued for those pre-closing obligations that are considered probable and reasonably estimable. Should circumstances change, increasing the likelihood of payments related to a specific indemnity, we will accrue a liability when future payment is probable and the amount is reasonably estimable.

Other Matters. We are party to a number of other lawsuits arising in the ordinary course of business, including product liability cases for products manufactured by us or third parties. We provide for costs relating to these matters when a loss is probable and the amount is reasonably estimable. Administrative costs related to these matters are expensed as incurred. The effect of the outcome of these matters on our future financial statements cannot be predicted with certainty as any such effect depends on the amount and timing of the resolution of such matters. While the results of litigation cannot be predicted with certainty, we believe that the final outcome of such other litigation is not likely to have a materially adverse effect on our business or prospects.

Note 11. Subsequent Events

On January 23, 2013, we delivered notice to redeem $22.5 million of the Senior Unsecured Notes at a redemption price of 103% plus accrued and unpaid interest on February 22, 2013. We expect to record a loss on early extinguishment of debt of $1.4 million on that date.

On January 30, 2013, our board of directors declared a dividend of $0.0175 per share on our common stock, payable on or about February 20, 2013, to stockholders of record at the close of business on February 11, 2013.

Item 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The following discussion should be read in conjunction with the unaudited condensed consolidated financial statements and notes thereto that appear elsewhere in this report. This report contains certain statements that may be deemed “forward-looking statements” within the meaning the Private Securities Litigation Reform Act of 1995. All statements that address activities, events or developments that the Company's management intends, expects, plans, projects, believes or anticipates will or may occur in the future are forward-looking statements. Examples of forward-looking statements include, but are not limited to, statements we make regarding the general municipal spending environment and the condition of our end markets. Forward-looking statements are based on certain assumptions and assessments made by management in light of their experience and their perception of historical trends, current conditions and expected future developments. Actual results and the timing of events may differ materially from those contemplated by the forward-looking statements due to a number of factors, including regional, national or global political, economic, business, competitive, market and regulatory conditions and the other factors that are described in the section entitled “RISK FACTORS” in Item 1A. of our annual report on Form 10-K for the year ended September 30, 2012 ("Annual Report"). Undue reliance should not be placed on any forward-looking statements. The Company does not have any intention or obligation to update forward-looking statements, except as required by law.

Overview

Organization

On October 3, 2005, Walter Energy acquired all outstanding shares of capital stock representing the Mueller Co. and Anvil businesses and contributed them to its U.S. Pipe business to form the Company. In June 2006, we completed an initial public offering of 28,750,000 shares of Series A common stock and in December 2006, Walter Energy distributed to its shareholders all of its equity interests in the Company, consisting of all of the Company's outstanding shares of Series B common stock. On January 28, 2009, each share of Series B common stock was converted into one share of Series A common stock and the Series A designation was discontinued.

On April 1, 2012, we sold the businesses comprising our former U.S. Pipe segment. U.S. Pipe's results of operations have been reclassified as discontinued operations for all periods presented.

Unless the context indicates otherwise, whenever we refer to a particular year, we mean the fiscal year ended or ending September 30 in that particular calendar year. We manage our businesses and report operations through two business segments, Mueller Co. and Anvil, based largely on the products sold and the customers served.

Business

Most of the net sales of Mueller Co. are for water infrastructure related directly to municipal spending and residential construction activity in the United States.

Spending on water infrastructure is based on the condition of the infrastructure systems and access to funding from existing resources, the issuance of debt, higher tax rates or higher water rates. Municipalities and water authorities may find it challenging to increase tax or water rates. We believe the general municipal spending environment continues to improve, although budget pressures and economic uncertainty persist. According to U.S. Census Bureau data at September 30, 2012, state and local tax receipts during the quarter ended September 30, 2012 grew at over 3.9% over the prior year period. The U.S. Census Bureau may revise published survey data from time to time.

We believe residential construction activity measures indicate the housing market is improving. U.S. Census Bureau data for housing starts, on a seasonally adjusted annualized basis, indicates that housing starts in December 2012 represented the fourth consecutive month of greater than 800,000 units. December 2012 housing activity of 954,000 starts was the highest level since June 2008. Furthermore, the December 2012 single family housing starts of 616,000 units was above 500,000 units for the ninth consecutive month and was the strongest since August 2008.

As another potential future indicator, U.S. Census Bureau data shows housing permits in December 2012 above 900,000 units for the second consecutive month. Total and single family permits grew 29% and 27%, respectively, in December 2012 on a year-over-year basis.

We believe an improving housing market would also bolster municipalities' fiscal condition, since local governments benefit from increased property taxes as well as connection and other ancillary fees associated with residential construction.

23

Overall we think the signs we are seeing in our water infrastructure markets are mostly positive, giving us more confidence that our markets have stabilized and we could see some continued growth.

Most of Anvil's net sales are driven by commercial construction, and we expect a slight decrease in shipment volumes in the second quarter year-over-year as we face some softness in our end markets, primarily oil & gas. Additionally, we expect to recognize the remaining higher per-unit overhead costs capitalized in inventory related to lower production levels in the second half of fiscal 2012 in cost of sales during the quarter ending March 31, 2013.

Raw material costs for both segments have continued to be relatively stable year-over-year and we expect average per-unit costs for 2013 could be slightly lower than those for 2012.

Consolidated Analysis

Net sales for the quarter ended December 31, 2012 increased to $245.1 million from $215.4 million in the prior year period. Net sales increased primarily due to approximately $27 million of higher shipment volumes across both segments.

Gross profit for the quarter ended December 31, 2012 increased to $57.1 million from $52.8 million in the prior year period. However, gross margin declined 120 basis points to 23.3% in the quarter ended December 31, 2012 from 24.5% in the prior year period. The favorable gross margin effects of increased shipment volumes, higher sales pricing, and improved raw material costs were more than offset by the unfavorable effects of higher per-unit overhead costs and other cost increases of approximately 260 basis points.

Selling, general and administrative expenses ("SG&A") in the quarter ended December 31, 2012 increased to $49.5 million from $46.5 million in the prior year period. SG&A increased primarily due to higher expenses associated with higher shipment volumes. However, SG&A decreased as a percent of net sales to 20.2% in the quarter ended December 31, 2012 compared to 21.6% in the prior year period.

Interest expense, net decreased $2.1 million in the quarter endedDecember 31, 2012 compared to prior year period due to $1.4 million of non-cash costs for terminated interest rate swap contracts in the quarter ended December 31, 2011 and $0.7 million due primarily to lower levels of total debt outstanding in the quarter ended December 31, 2012. The components of interest expense, net are detailed below.

Segment Analysis

Mueller Co.

Net sales in the quarter endedDecember 31, 2012 increased to $151.1 million from $128.1 million in the prior year period. Net sales increased primarily due to approximately $22 million of higher shipment volumes. Domestic unit shipments increased for valves, hydrants and brass products in the quarter endedDecember 31, 2012 compared to the prior year period. Also, net sales of our newer technology products more than doubled in the quarter endedDecember 31, 2012 compared to the prior year period. Over half of the $23 million net sales increase was attributable to our metering products.

Gross profit for the quarter endedDecember 31, 2012 increased to $32.9 million from $28.5 million in the prior year period primarily due to higher shipment volumes. However, gross margin decreased to 21.8% for the quarter endedDecember 31, 2012 compared to 22.2% in the prior year period primarily due to the increased sales of our newer technology

25

products and services, which had lower gross margins, and an unfavorable mix of Henry Pratt valves sold in the quarter endedDecember 31, 2012 compared to the prior year period.

SG&A in the quarter endedDecember 31, 2012 increased to $24.1 million compared to $23.4 million in the prior year period was primarily due to higher shipment volumes.

Anvil

Net sales in the quarter endedDecember 31, 2012 increased to $94.0 million from $87.3 million in the prior year period. The increase in net sales was primarily due to approximately $5 million of higher shipment volumes primarily of Anvil's fire protection and mechanical market products. Net sales to Anvil's oil & gas market, which comprise approximately 20% of Anvil's net sales, had minimal growth in the quarter endedDecember 31, 2012 after exhibiting strong growth in fiscal 2012.

Gross profit in the quarter endedDecember 31, 2012 decreased to $24.2 million from $24.3 million in the prior year period. The increase attributable to higher net sales was more than offset by increased inventory costs reflecting higher per-unit overhead costs driven by lower production in the six months ended September 30, 2012. Gross margin declined to 25.7% in the quarter endedDecember 31, 2012 compared to 27.8% in the prior year period. Increased inventory costs reduced gross margin by approximately 350 basis points.

SG&A increased to $18.3 million in the quarter endedDecember 31, 2012 compared to $16.5 million in the prior year period. This was primarily the result of increased selling costs commensurate with increased shipment volumes.

Corporate

SG&A increased to $7.1 million in the quarter ended December 31, 2012 from $6.6 million in the prior year period primarily due to timing differences for professional fees.

Liquidity and Capital Resources

We had cash and cash equivalents of $74.5 million at December 31, 2012. We also had $122.1 million of borrowing capacity under our ABL Agreement using December 31, 2012 data.

On April 1, 2012, we sold our former U.S. Pipe segment and received proceeds of $94.0 million in cash, subject to adjustments, and the agreement by the purchaser to reimburse us for expenditures to settle certain previously-existing liabilities estimated at $10.1 million at March 31, 2012. During the quarter ended December 31, 2012, we received an additional $4.5 million in cash for certain purchase price adjustments and reduced our loss on sale of discontinued operations accordingly. Additional purchase price adjustments related to closing date balances, which would increase the purchase price by $1.0 million if resolved in our favor, remain in dispute.

On January 23, 2013, we delivered notice to redeem $22.5 million of the Senior Unsecured Notes at a redemption price of 103% plus accrued and unpaid interest. The redemption date is February 22, 2013. We expect to record a loss on early extinguishment of debt of $1.4 million.

Cash flows from operating activities from continuing operations are categorized below.

	Three months ended
	December 31,
	2012			2011
	(in millions)
Collections from customers	$	274.4		$	241.1
Disbursements other than interest and income taxes	(257.7		)	(212.7		)
Interest payments, net	(16.0		)	(16.3		)
Income tax payments, net	(0.1		)	(0.2		)
	$	0.6		$	11.9

Collections of receivables were higher during the three months endedDecember 31, 2012 compared to the prior year period primarily related to the increased net sales compared to a year ago.

Increased disbursements other than interest and income taxes during the three months endedDecember 31, 2012 reflect higher purchasing activity associated with higher net sales and general timing differences of disbursements related to the

26

purchase of material, labor and overhead. Also, we contributed $4.0 million to our pension plans in the three months endedDecember 31, 2011 and there were no comparable contributions during the three months ended December 31, 2012.

Capital expenditures were $6.2 million during the three months endedDecember 31, 2012 compared to $5.3 million in the prior year period. We estimate 2013 capital expenditures will be between $30 million and $34 million.

Our U.S. pension plan was 103% funded at January 1, 2012 (the most recent date this analysis has been performed) under the provisions of the Pension Protection Act. This reflects the revised governmental guidance of the Moving Ahead for Progress in the 21^st Century Act . As a result of the MAP-21 changes, we do not expect to make any contributions to our U.S. pension plan during 2013. A significant portion of the assets invested in our defined benefit pension plans is invested in equity securities. If we lower our estimated rate of return on these assets, pension expense and our required contributions to these plans may increase.

We anticipate that our existing cash, cash equivalents and borrowing capacity combined with our expected cash flows from operating activities will be sufficient to meet our anticipated operating expenses, capital expenditures and debt service obligations as they become due through December 31, 2013. However, our ability to make these payments will depend partly upon our future operating performance, which will be affected by general economic, financial, competitive, legislative, regulatory, business and other factors beyond our control.

ABL Agreement

On December 18, 2012, we entered into a first amendment to our ABL Agreement, dated August 26, 2010. This amendment, among other things, provides for the following:

• a reduction of $50 million in the size of the revolving credit facility to $225 million;

•a 100 basis point per annum reduction in the interest rate margins;

• a reduction in the commitment fee to either 0.375% per annum or 0.25% per annum, based on daily average availability during the previous calendar quarter, from 0.50% per annum;

• the extension of the maturity date to the earlier of (1) December 18, 2017 and (2) 60 days prior to the final maturity of our 7.375% Senior Subordinated Notes;

• additional flexibility for us to incur debt, make investments (including acquisitions), dispose of assets and make restricted payments (whether as dividends or junior debt repayments); and

•a reduction in the springing consolidated fixed charge coverage ratio to 1.0:1.0 from 1.1:1.0.

At December 31, 2012, the ABL Agreement consisted of a revolving credit facility for up to $225 million of revolving credit borrowings, swing line loans and letters of credit. The ABL Agreement also permits us to increase the size of the credit facility by an additional $150 million in certain circumstances subject to adequate borrowing base availability. We may borrow up to $25 million through swing line loans and may have up to $60 million of letters of credit outstanding.

Borrowings under the ABL Agreement bear interest at a floating rate equal to LIBOR plus a margin ranging from 175 to 225 basis points, or a base rate, as defined in the ABL Agreement, plus a margin ranging from 75 to 125 basis points. At December 31, 2012, the applicable LIBOR-based margin was 200 basis points.

Our obligations are secured by a first-priority perfected lien on all of our U.S. receivables and inventory, certain cash and other supporting obligations. Borrowings are not subject to any financial maintenance covenants unless excess availability is less than the greater of $22.5 million and 10% of the aggregate commitments under the ABL Agreement. As measured using December 31, 2012 data, excess availability as reduced by outstanding letters of credit and accrued fees and expenses of $34.6 million was $122.1 million.

The ABL Agreement is subject to mandatory prepayments if total outstanding borrowings under the ABL Agreement are greater than the aggregate commitments under the revolving credit facility or if we dispose of overdue accounts receivable in certain circumstances. The borrowing base under the ABL Agreement is equal to the sum of (a) 85% of the value of eligible accounts receivable and (b) the lesser of (i) 65% of the value of eligible inventory or (ii) 85% of the net orderly liquidation value of the value of eligible inventory, less certain reserves. Prepayments can be made at any time with no penalty.

Substantially all of our U.S. subsidiaries are borrowers under the ABL Agreement and are jointly and severally liable for any outstanding borrowings. Our obligations under the ABL Agreement are secured by a first-priority perfected lien on all of our U.S. inventory, accounts receivable, certain cash and other supporting obligations.

27

The ABL Agreement contains customary negative covenants and restrictions on our ability to engage in specified activities, such as:

• limitations on other debt, liens, investments and guarantees;

• restrictions on dividends and redemptions of our capital stock and prepayments and redemptions of debt; and

• restrictions on mergers and acquisition, sales of assets and transactions with affiliates.

8.75% Senior Unsecured Notes

We owed $202.5 million aggregate principal amount of 8.75% Senior Unsecured Notes at December 31, 2012. Interest on the Senior Unsecured Notes is paid semi-annually and the principal is due September 2020. On January 23, 2013, we delivered notice to redeem $22.5 million aggregate principal amount at a redemption price of 103% plus accrued and unpaid interest on February 22, 2013. We may redeem up to $33.8 million aggregate principal amount of the Senior Unsecured Notes at a redemption price of 108.75%, plus accrued and unpaid interest, with the net cash proceeds from certain equity offerings prior to September 2013. After August 2015, the Senior Unsecured Notes may be redeemed at specified redemption prices plus accrued and unpaid interest. Upon a “Change of Control” (as defined in the indenture securing the Senior Unsecured Notes), we are required to offer to purchase the outstanding Senior Unsecured Notes at a purchase price of 101%, plus accrued and unpaid interest. The Senior Unsecured Notes are secured by the guarantees of essentially all of our U.S. subsidiaries, but are subordinate to borrowings under the ABL Agreement.

7.375%Senior Subordinated Notes

We owed $420 million of principal of 7.375% Senior Subordinated Notes at December 31, 2012. Interest on the Senior Subordinated Notes is payable semi-annually and the principal is due June 2017. We may redeem any portion of the Senior Subordinated Notes at specified redemption prices plus accrued and unpaid interest, subject to limitations under our ABL agreement and the indenture related to our Senior Unsecured Notes. Upon a “Change of Control” (as defined in the indenture securing the Senior Subordinated Notes), we are required to offer to purchase the outstanding Senior Subordinated Notes at 101%, plus accrued and unpaid interest. The Senior Subordinated Notes are secured by the guarantees of essentially all of our U.S. subsidiaries, but are subordinate to the borrowings under the ABL Agreement and the Senior Unsecured Notes.

Off-Balance Sheet Arrangements

We do not have any relationships with unconsolidated entities or financial partnerships, such as entities often referred to as structured finance or special purpose entities, which could have been established for the purpose of facilitating off-balance sheet arrangements or other contractually narrow or limited purposes. In addition, we do not have any undisclosed borrowings or debt, any derivative contracts or synthetic leases. Therefore, we are not exposed to any financing, liquidity, market or credit risk that could have arisen if we had engaged in such relationships.

We use letters of credit and surety bonds in the ordinary course of business to ensure the performance of contractual obligations. At December 31, 2012, we had $34.4 million of letters of credit and $50.5 million of surety bonds outstanding.

Seasonality

Our business is dependent upon the construction industry, which is seasonal due to the impact of cold weather conditions. Net sales and operating income have historically been lowest in the quarterly periods ending December 31 and March 31 when the northern United States and all of Canada generally face weather conditions that restrict significant construction activity.

28

Item 4. CONTROLS AND PROCEDURES

During the quarter ended December 31, 2012, there were no changes in our internal control over financial reporting that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

We maintain disclosure controls and procedures that are designed to ensure that information required to be disclosed in the reports we file or submit under the Exchange Act, is recorded, processed, summarized and reported within the time periods specified in the rules and forms of the Securities and Exchange Commission and that such information is accumulated and communicated to our management, including the Chief Executive Officer and the Chief Financial Officer as appropriate, to allow timely decisions regarding required disclosure.

Our Chief Executive Officer and our Chief Financial Officer have concluded, based on an evaluation of the effectiveness of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) of the Securities Exchange Act of 1934, as amended) by our management, with the participation of our Chief Executive Officer and our Chief Financial Officer, that such disclosure controls and procedures were effective as of the end of the period covered by this report.

Our management, including the Chief Executive Officer and Chief Financial Officer, does not expect that our disclosure controls can prevent all errors and all fraud. A control system, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. There are inherent limitations in all control systems, including the realities that judgments in decision-making can be faulty, and that breakdowns can occur because of simple error or mistake. Additionally, controls can be circumvented by the individual acts of one or more persons. The design of any system of controls also is based in part upon certain assumptions about the likelihood of future events, and, while our disclosure controls and procedures are designed to be effective under circumstances where they should reasonably be expected to operate effectively, there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions. Because of the inherent limitations in any control system, misstatements due to error or fraud may occur and not be detected.

Discontinued Operations and Assets Held for Sale

Discontinued Operations

On April 1, 2012, we sold our former U.S. Pipe segment and received proceeds of $94.0 million in cash, subject to adjustments, and the agreement by the purchaser to reimburse us for expenditures to settle certain previously-existing liabilities estimated at $10.1 million at March 31, 2012. During the quarter ended December 31, 2012, we received $4.5 million in cash for certain purchase price adjustments and reduced our loss on sale of discontinued operations accordingly. Additional purchase price adjustments related to closing date balances, which would increase the purchase price by $1.0 million if resolved in our favor, remain in dispute.

The table below represents a summary of the operating results for the U.S. Pipe discontinued operations.

Organization And Basis Of Presentation [Abstract]

Organization

Organization

Mueller Water Products, Inc., a Delaware corporation, together with its consolidated subsidiaries, operates in two business segments: Mueller Co. and Anvil. Mueller Co. manufactures valves for water and gas systems, including butterfly, iron gate, tapping, check, plug and ball valves, as well as dry-barrel and wet-barrel fire hydrants and a broad range of metering, leak detection and pipe condition assessment products for the water infrastructure industry. Anvil manufactures and sources a broad range of products, including a variety of fittings, couplings, hangers and related products. The “Company,” “we,” “us” or “our” refer to Mueller Water Products, Inc. and its subsidiaries or their management. With regard to the Company's segments, “we,” “us” or “our” may also refer to the segment being discussed or its management.

On April 1, 2012, we sold the businesses comprising our former U.S. Pipe segment to USP Holdings Inc., an affiliate of Wynnchurch Capital, Ltd (“Wynnchurch”). U.S. Pipe's results of operations have been reclassified as discontinued operations, and its assets and liabilities reclassified as held for sale, for all prior periods.

Our consolidated financial statements are prepared in conformity with accounting principles generally accepted in the United States of America ("GAAP"), which require us to make certain estimates and assumptions that affect the reported amounts of assets, liabilities, sales and expenses and the disclosure of contingent assets and liabilities for the reporting periods. Actual results could differ from those estimates. All significant intercompany balances and transactions have been eliminated. In our opinion, all normal and recurring adjustments that we consider necessary for a fair financial statement presentation have been made. Certain reclassifications have been made to previously reported amounts to conform to the current presentation. The condensed consolidated balance sheet data at September 30, 2012 was derived from audited financial statements, but does not include all disclosures required by GAAP.

Unless the context indicates otherwise, whenever we refer to a particular year, we mean the fiscal year ended or ending September 30 in that particular calendar year.

Commitments and Contingencies

We are involved in various legal proceedings that have arisen in the normal course of operations, including the proceedings summarized below. The effect of the outcome of these matters on our financial statements cannot be predicted with certainty as any such effect depends on the amount and timing of the resolution of such matters. Other than the litigation described below, we do not believe that any of our outstanding litigation would have a material adverse effect on our business or prospects.

Environmental. We are subject to a wide variety of laws and regulations concerning the protection of the environment, both with respect to the operations at many of our properties and with respect to remediating environmental conditions that may exist at our own or other properties. We strive to comply with federal, state and local environmental laws and regulations. We accrue for environmental expenses resulting from existing conditions that relate to past operations when the costs are probable and reasonably estimable.

In the acquisition agreement pursuant to which a predecessor to Tyco sold our Mueller Co. and Anvil businesses to the prior owners of these businesses in August 1999, Tyco agreed to indemnify us and our affiliates, among other things, for all “Excluded Liabilities.” Excluded Liabilities include, among other things, substantially all liabilities relating to the time prior to August 1999, including environmental liabilities. The indemnity survives indefinitely. Tyco's indemnity does not cover liabilities to the extent caused by us or the operation of our businesses after August 1999, nor does it cover liabilities arising with respect to businesses or sites acquired after August 1999. Since 2007, Tyco has engaged in multiple corporate restructurings, split-offs and divestitures. While none of these transactions directly affects the indemnification obligations of the Tyco indemnitors under the 1999 acquisition agreement, the result of such transactions is that the assets of, and control over, such Tyco indemnitors has changed. Should any of these Tyco indemnitors become financially unable or fail to comply with the terms of the indemnity, we may be responsible for such obligations or liabilities.

In September 1987, we implemented an Administrative Consent Order (“ACO”) for our Burlington, New Jersey property, which was required under the New Jersey Environmental Cleanup Responsibility Act (now known as the Industrial Site Recovery Act). The ACO required soil and ground-water cleanup, and we completed, and received final approval on, the soil cleanup required by the ACO. We retained this property related to the sale of our former U.S. Pipe segment. We expect ground-water issues as well as issues associated with the demolition of former manufacturing facilities at this site will continue and remediation by us could be required. Long-term ground-water monitoring may also be required, but we do not know how long such monitoring would be required and do not believe monitoring or further remediation costs, if any, will have a material adverse effect on any of our financial statements.

On July 13, 2010, Rohcan Investments Limited (“Rohcan”), the former owner of property leased by Mueller Canada Ltd. and located in Milton, Ontario, filed suit against Mueller Canada Ltd. and its directors seeking C$10.0 million in damages arising from the defendants' alleged environmental contamination of the property and breach of lease. Mueller Canada Ltd. leased the property from 1988 through 2008. We are pursuing indemnification from a former owner for certain potential liabilities that are alleged in this lawsuit, and we have accrued for other liabilities not covered by indemnification.  On December 7, 2011, the Court denied the plaintiff's motion for summary judgment.

Walter Energy-related Income Taxes. Each member of a consolidated group for federal income tax purposes is severally liable for the federal income tax liability of each other member of the consolidated group for any year in which it is a member of the group at any time during such year. Each member of the Walter Energy consolidated group, which included us through December 14, 2006, is also jointly and severally liable for pension and benefit funding and termination liabilities of other group members, as well as certain benefit plan taxes. Accordingly, we could be liable under such provisions in the event any such liability is incurred, and not discharged, by any other member of the Walter Energy consolidated group for any period during which we were included in the Walter Energy consolidated group.

A dispute exists with regard to federal income taxes for 1980 through 1994 allegedly owed by the Walter Energy consolidated group. According to Walter Energy's last available public filing on the matter, Walter Energy's management estimated that the amount of tax claimed by the IRS was approximately $34.0 million for issues currently in dispute in bankruptcy court for matters unrelated to us. This amount is subject to interest and penalties. Of the $34.0 million in claimed tax, $21.0 million represents issues in which the IRS is not challenging the deductibility of the particular expense but only whether such expense is deductible in a particular year. Walter Energy's management believes that Walter Energy's financial exposure should be limited to interest and possible penalties and the amount of any tax claimed will be offset by favorable adjustments in other years.

In addition, the IRS previously issued a Notice of Proposed Deficiency assessing additional tax of $82.2 million for the fiscal years ended May 31, 2000 through December 31, 2005. Walter Energy filed a formal protest with the IRS, but had not reached a final resolution with the Appeals Division at December 31, 2012. The unresolved issues relate primarily to Walter Energy's method of recognizing revenue on the sale of homes and related interest on the installment notes receivable. The items at issue relate primarily to the timing of revenue recognition and consequently, should the IRS prevail on its positions, Walter Energy's financial exposure should be limited to interest and penalties. As a matter of law, we are jointly and severally liable for any final tax determination for any year in which any of our subsidiaries were members of the Walter Energy consolidated group, which means that we would be liable in the event Walter Energy is unable to pay any amounts owed. Walter Energy has disclosed that it believes its filing positions have substantial merit and that it intends to defend vigorously any claims asserted.

Walter Energy effectively controlled all of our tax decisions for periods during which we were a member of the Walter Energy consolidated group for federal income tax purposes and certain combined, consolidated or unitary state and local income tax groups. Under the terms of the income tax allocation agreement between us and Walter Energy dated May 26, 2006, we generally compute our tax liability on a stand-alone basis, but Walter Energy has sole authority to respond to and conduct all tax proceedings (including tax audits) relating to our federal income and combined state returns, to file all such returns on our behalf and to determine the amount of our liability to (or entitlement to payment from) Walter Energy for such previous periods. This arrangement may result in conflicts between Walter Energy and us.

Our separation from Walter Energy on December 14, 2006 was intended to qualify as a tax-free spin-off under Section 355 of the Internal Revenue Code. In addition, the tax allocation agreement provides that if the spin-off is determined not to be tax-free pursuant to Section 355, we generally will be responsible for any taxes incurred by Walter Energy or its shareholders if such taxes result from certain of our actions or omissions and for a percentage of any such taxes that are not a result of our actions or omissions or Walter Energy's actions or omissions or taxes based upon our market value relative to Walter Energy's market value. Additionally, to the extent that Walter Energy was unable to pay taxes, if any, attributable to the spin-off and for which it is responsible under the tax allocation agreement, we could be liable for those taxes as a result of being a member of the Walter Energy consolidated group for the year in which the spin-off occurred.

In accordance with the income tax allocation agreement, Walter Energy used certain tax assets of one of our predecessors in its calendar 2006 tax return for which payment to us is required. The income tax allocation agreement only requires Walter Energy to make the payment upon realization of the tax benefit by receiving a refund or otherwise offsetting taxes due. Walter Energy currently owes us $11.6 million, which includes recent tax audit and amended tax return adjustments, that is payable pending completion of an IRS audit of Walter Energy's 2006 tax year and the related refund of tax from that year. This receivable is included in other current assets at December 31, 2012.

Indemnifications. We are a party to contracts in which it is common for us to agree to indemnify third parties for certain liabilities that arise out of or relate to the subject matter of the contract. In some cases, this indemnity extends to related liabilities arising from the negligence of the indemnified parties, but usually excludes any liabilities caused by gross negligence or willful misconduct. We cannot estimate the potential amount of future payments under these indemnities until events arise that would trigger a liability under the indemnities.

Additionally, in connection with the sale of assets and the divestiture of businesses, such as the divestiture of our U.S. Pipe segment, we may agree to indemnify buyers and related parties for certain losses or liabilities incurred by these parties with respect to: (i) the representations and warranties made by us to these parties in connection with the sale and (ii) liabilities related to the pre-closing operations of the assets or business sold. Indemnities related to pre-closing operations generally include certain environmental and tax liabilities and other liabilities not assumed by these parties in the transaction.

Indemnities related to the pre-closing operations of sold assets or businesses normally do not represent additional liabilities to us, but simply serve to protect these parties from potential liability associated with our obligations existing at the time of the sale. As with any liability, we have accrued for those pre-closing obligations that are considered probable and reasonably estimable. Should circumstances change, increasing the likelihood of payments related to a specific indemnity, we will accrue a liability when future payment is probable and the amount is reasonably estimable.

Other Matters. We are party to a number of other lawsuits arising in the ordinary course of business, including product liability cases for products manufactured by us or third parties. We provide for costs relating to these matters when a loss is probable and the amount is reasonably estimable. Administrative costs related to these matters are expensed as incurred. The effect of the outcome of these matters on our future financial statements cannot be predicted with certainty as any such effect depends on the amount and timing of the resolution of such matters. While the results of litigation cannot be predicted with certainty, we believe that the final outcome of such other litigation is not likely to have a materially adverse effect on our business or prospects.

Derivative Instrument Detail [Abstract]

Derivative Financial Instruments

Derivative Financial Instruments

Our ongoing business operations expose us to commodity price risk and interest rate risk that we have previously managed to some extent using derivative instruments. We have used natural gas swap contracts to manage the price risk associated with purchases of natural gas used in certain of our manufacturing processes and interest rate swap contracts to manage interest rate risk associated with our variable-rate borrowings. During 2010, we terminated all of our remaining interest rate swap contracts and no new interest rate swap contracts have been initiated. During 2012, we terminated our remaining natural gas swap contract.

We had designated our natural gas swap contracts and interest rate swap contracts as cash flow hedges of our purchases of natural gas and our interest payments, respectively. As a result, to the extent the hedges were effective, the changes in the fair value of these contracts prior to settlement were reported as a component of other comprehensive income (loss) and reclassified into earnings in the periods during which the hedged transactions affected earnings. Gains and losses on those contracts representing either hedge ineffectiveness or hedge components excluded from the assessment of effectiveness were recognized in earnings as they occurred.

Our derivative contracts were recorded at fair value using publicly observable data such as market natural gas prices and market interest rates. We did not have any derivative contracts outstanding at December 31, 2012 or September 30, 2012.

In the quarter endedDecember 31,2011, we reclassified $1.4 million related to previously terminated interest rate swap contracts to interest expense from accumulated other comprehensive loss.

ABL Agreement. On December 18, 2012, we entered into a first amendment to our asset based lending agreement dated August 26, 2010 (the “ABL Agreement”). This amendment, among other things, provides for the following:

• a reduction of $50.0 million in the size of the revolving credit facility to $225.0 million;

•a 100 basis point per annum reduction in the interest rate margins;

• a reduction in the commitment fee to either 0.375% per annum or 0.25% per annum, based on daily average availability during the previous calendar quarter, from 0.50% per annum;

• the extension of the maturity date to the earlier of (1) December 18, 2017 and (2) 60 days prior to the final maturity of our 7.375% Senior Subordinated Notes;

• additional flexibility for us to incur debt, make investments (including acquisitions), dispose of assets and make restricted payments (whether as dividends or junior debt repayments); and

•a reduction in the springing consolidated fixed charge coverage ratio to 1.0:1.0 from 1.1:1.0.

The ABL Agreement also permits us to increase the size of the credit facility by an additional $150 million in certain circumstances subject to adequate borrowing base availability. We may borrow up to $25 million through swing line loans and may have up to $60 million of letters of credit outstanding.

Borrowings under the ABL Agreement bear interest at a floating rate equal to LIBOR plus a margin ranging from 175 to 225 basis points, or a base rate, as defined in the ABL Agreement, plus a margin ranging from 75 to 125 basis points. At December 31, 2012, the applicable LIBOR-based margin was 200 basis points.

Our obligations under the ABL Agreement are secured by a first-priority perfected lien on all of our U.S. receivables and inventory, certain cash and other supporting obligations. Borrowings are not subject to any financial maintenance covenants unless excess availability is less than the greater of $22.5 million and 10% of the aggregate commitments under the ABL Agreement. Excess availability based on December 31, 2012 data, as reduced by outstanding letters of credit and accrued fees and expenses of $34.6 million, was $122.1 million.

8.75%Senior Unsecured Notes. The 8.75% Senior Unsecured Notes (the “Senior Unsecured Notes”) mature in September 2020 and bear interest at 8.75%, paid semi-annually. Based on quoted market prices, the outstanding Senior Unsecured Notes had a fair value of $230.9 million at December 31, 2012.

On January 23, 2013, we delivered notice to redeem $22.5 million aggregate principal amount on February 22, 2013 at a redemption price of 103% plus accrued and unpaid interest. This amount is included in current portion of long-term debt at December 31, 2012.

We may also redeem up to $33.8 million of the Senior Unsecured Notes at a redemption price of 108.75%, plus accrued and unpaid interest, with the net cash proceeds from certain equity offerings prior to September 2013. After August 2015, we may redeem the Senior Unsecured Notes at specified redemption prices plus accrued and unpaid interest. Upon a Change of Control (as defined in the indenture securing the Senior Unsecured Notes), we are required to offer to purchase the outstanding Senior Unsecured Notes at a purchase price of 101% plus accrued and unpaid interest. The Senior Unsecured Notes are subordinate to borrowings under the ABL Agreement.

The indenture securing the Senior Unsecured Notes contains customary covenants and events of default, including covenants that limit our ability to incur debt, pay dividends and make investments. Substantially all of our U.S. subsidiaries guarantee the Senior Unsecured Notes. We believe we were compliant with these covenants at December 31, 2012 and expect to remain in compliance through December 31, 2013.

7.375%Senior Subordinated Notes. The 7.375% Senior Subordinated Notes (the “Senior Subordinated Notes”) mature in June 2017 and bear interest at 7.375%, paid semi-annually. Based on quoted market prices, the outstanding Senior Subordinated Notes had a fair value of $433.7 million at December 31, 2012.

We may redeem any portion of the Senior Subordinated Notes at specified redemption prices plus accrued and unpaid interest, subject to restrictions in the Senior Unsecured Notes. Upon a Change of Control (as defined in the indenture securing the Senior Subordinated Notes), we are required to offer to purchase the outstanding Senior Subordinated Notes at a purchase price of 101%, plus accrued and unpaid interest. The Senior Subordinated Notes are subordinate to borrowings under the ABL Agreement and the Senior Unsecured Notes.

The indenture securing the Senior Subordinated Notes contains customary covenants and events of default, including covenants that limit our ability to incur debt, pay dividends and make investments. Substantially all of our U.S. subsidiaries guarantee the Senior Subordinated Notes. We believe we were compliant with these covenants at December 31, 2012 and expect to remain in compliance through December 31, 2013.

The amortization of unrecognized prior service cost and of actuarial losses, net of tax, are recorded as components of other comprehensive income (loss).

Our U.S. pension plan was 103% funded at January 1, 2012 under the provisions of the Pension Protection Act. This reflects the revised governmental guidance of Moving Ahead for Progress in the 21st Century (“MAP-21”). As a result of the MAP-21 changes, we do not expect to make any contributions to our U.S. pension plan during 2013. For financial reporting purposes, our pension plan obligations were 86% funded at September 30, 2012.

On April 1, 2012, we changed certain provisions of our pension and postretirement benefit plans affecting U.S. Pipe participants in these plans. These changes vested all accumulated pension benefits and then froze the plan such that no additional pension benefits would accumulate. Postretirement medical benefits substantially ceased on December 31, 2012. During the three months ended December 31, 2012, we recorded a benefit of $7.4 million, which is included in income from discontinued operations, related to this cessation of benefits.

The assets of the defined benefit pension plans at December 31, 2012 and September 30, 2012, by level within the fair value hierarchy, are presented below.

Stock-based Compensation Plans

Share-based Compensation, Allocation and Classification in Financial Statements [Abstract]

Stock-based Compensation Plans

Stock-based Compensation Plans

During the quarter ended December 31, 2012, we granted cash-settled and stock-settled performance shares under our Amended and Restated 2006 Mueller Water Products, Inc. Stock Incentive Plan (the "2006 Stock Plan"). The performance shares are part of multi-year award cycles consisting of annual performance periods coinciding with our fiscal years, with performance goals established within 90 days of the beginning of each performance period by the Compensation and Human Resources Committee of our board of directors. Performance shares do not convey voting rights or earn dividends. Performance shares vest on the last day of the award cycle, unless vested sooner due to change-of-control, death, disability or retirement after accumulation of the required number of points, which are a function of age and years of service, provided that the participant continues to be employed by us through that date. We will distribute the related cash and common stock within 90 days of the end of the award cycle.

A cash-settled performance share entitles the recipient to a cash payment determined at the end of each of two annual performance periods. The amount of cash to be distributed equals the product of the number of performance shares granted multiplied by a performance factor ranging from 0.0 to 2.0 and by the closing price of our common stock on the last day of the award cycle. Compensation expense for cash-settled performance shares is charged against income over the applicable performance period based on the estimated performance factor and the closing price per share of our common stock at each balance sheet date. Outstanding cash-settled performance shares had a fair value of $5.61 per share and a total fair value of $2.1 million at December 31, 2012.

A stock-settled performance share entitles the recipient to receive a number of shares of our common stock determined at the end of each of three performance periods. The number of shares of our common stock issuable equals the number of performance shares granted multiplied by a performance factor that ranges from 0.0 to 2.0. Compensation expense for stock-settled performance shares is charged against income over the applicable performance period based on the estimated performance factor and the grant-date price of our common stock.

During the quarter ended December 31, 2011, the Company adopted the Mueller Water Products, Inc. Phantom Plan (the "Phantom Plan"). Phantom Plan awards entitle a recipient to a per-award cash payment equal to the closing price per share of our common stock on the vesting date. Awards generally vest in thirds on successive anniversaries of the grant date. Compensation expense for Phantom Plan awards is charged against income over the vesting period, based on the closing stock price at each balance sheet date until vested. Outstanding Phantom Plan awards had a fair value of $5.61 per award and a total fair value of $3.5 million at December 31, 2012.

We recorded stock-based compensation expense of $2.3 million during the three months endedDecember 31, 2012, and $1.4 million during the three months endedDecember 31, 2011. At December 31, 2012, there was approximately $8.4 million of unrecognized compensation expense related to stock-based awards.

Because the effect of including normally dilutive securities in the earnings per share calculation is antidilutive in loss periods, we exclude all stock-based compensation instruments from the calculations of diluted earnings per share in such periods. Accordingly, we excluded 0.8 million of such instruments from the calculation of diluted earnings per share for the three months endedDecember 31, 2011.

We granted stock-based compensation awards under the 2006 Stock Plan, Mueller Water Products, Inc. 2006 Employee Stock Purchase Plan and Phantom Plan during the three months endedDecember 31, 2012 as follows.    

	Number granted	Weighted average grant date fair value per instrument		Total grant date fair value (in millions)

After including the tax effect of the loss on the sale of U.S. Pipe, our U.S. deferred tax liabilities are insufficient to fully support our U.S. deferred tax assets, which include net operating loss carryforwards.  Accordingly, we initially recorded income tax expense to establish valuation allowances related to our overall deferred tax assets during the quarter ended March 31, 2012.

We reevaluate the need for a valuation allowance against the U.S. deferred tax assets each quarter, considering results to date, projections of taxable income, tax planning strategies and reversing taxable temporary differences. During the quarter ended December 31, 2012, we decreased our U.S. deferred tax valuation allowance by $4.6 million, including $0.8 million included in other comprehensive income. Notwithstanding the valuation allowance, our net operating loss carryforwards remain available to offset future taxable earnings.

The components of income tax benefit on continuing operations are provided below.

At December 31, 2012 and September 30, 2012, the gross liabilities for unrecognized income tax benefits were $4.3 million and $4.3 million, respectively.

We recognize interest related to uncertain income tax positions as interest expense and would recognize any penalties that may be incurred as selling, general and administrative expense. At December 31, 2012 and September 30, 2012, we had $0.9 million and $0.9 million, respectively, of accrued interest expense related to uncertain tax positions.

Generally, our state income tax returns are closed for years prior to 2006, except to the extent of our state net operating loss carryforwards, and our Canadian income tax returns are closed for years prior to 2005. During 2012, we concluded an audit by the Internal Revenue Service (the "IRS") for the years 2007 through 2010 with no adverse changes. We are also under audit by several states at various levels of completion. We do not have any material unpaid assessments.
