MUELLER WATER PRODUCTS, INC. AND SUBSIDIARIES
NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
FOR THE THREE AND SIX MONTHS ENDED MARCH 31, 2022
(UNAUDITED)
Note 1. Organization and Basis of Presentation
Mueller Water Products, Inc., a Delaware corporation, together with its consolidated subsidiaries, operates in two business segments: Water Flow Solutions and Water Management Solutions. These segments are based on a management reorganization that became effective October 1, 2021; prior period information has been recast to conform to the current presentation. Water Flow Solutions’ product portfolio includes iron gate valves, specialty valves and service brass products. Water Management Solutions’ product and service portfolio includes fire hydrants, repair and installation, natural gas, metering, leak detection, pressure control and software products. The “Company,” “we,” “us” or “our” refer to Mueller Water Products, Inc. and its subsidiaries, and may also refer to the segment being discussed.
On December 3, 2018, we completed our acquisition of Krausz Industries Development Ltd. and subsidiaries (“Krausz”). During the quarter ended March 31, 2021, we aligned the consolidation of the financial statements of Krausz in the Company’s consolidated financial statements, eliminating the previous inclusion of Krausz financial statements with a one-month reporting lag. In accordance with applicable accounting literature, the elimination of the one-month reporting lag is considered to be a change in accounting principle. We believe this change in accounting principle is preferable as the financial statements of all of our subsidiaries are now reported on the same basis, providing the most current information available. The effect of the elimination of the reporting lag during the year ended September 30, 2021 resulted in an increase of $6.0 million to net sales and an increase of $1.4 million to operating income. We concluded that the effect of this change is not material to the balance sheets, statements of operations, statements of cash flows, net income and earnings per share and therefore have not retrospectively applied this change.
On June 14, 2021, we acquired all the outstanding capital stock of i2O Water Ltd (“i2O”), a provider of pressure management solutions to more than 100 water companies in 45 countries. The consolidated balance sheet at September 30, 2021 included the preliminary estimated fair values of the net assets of i2O. The accounting for this business combination became final during the three months ended March 31, 2022. The results of i2O’s operations and cash flows subsequent to the acquisition are included in the Company’s consolidated statement of operations and consolidated statement of cash flows, respectively. Refer to Note 2. for additional disclosures related to the acquisition.
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 in recording assets, liabilities, sales and expenses as well as in the disclosure of contingent assets and liabilities. Actual results could differ from those estimates. All significant intercompany balances and transactions have been eliminated. These condensed consolidated financial statements should be read in conjunction with the consolidated financial statements included in our Annual Report on Form 10-K for the year ended September 30, 2021. In our opinion, all normal and recurring adjustments that we consider necessary for a fair financial statement presentation have been made. The condensed consolidated balance sheet at September 30, 2021 was derived from audited financial statements, but it does not include all disclosures required by GAAP.
Our business is seasonal as a result of cold weather conditions. Net sales and operating income historically have been lowest in the three month 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.

In preparing these financial statements in conformity with GAAP, we have considered and, where appropriate, included the effects of the COVID-19 pandemic on our operations. The pandemic continues to provide significant challenges to the U.S. and global economies.

Unless the context indicates otherwise, whenever we refer to a particular year, we mean our fiscal year ended or ending September 30 in that particular calendar year.
Recently Adopted Accounting Guidance
During 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Codification (“ASC”) 326 - Current Expected Credit Losses to replace the “incurred loss” impairment approach with an “expected loss” approach, which requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates. We completed historical and forward-looking analyses for receivables and adopted this guidance effective October 1, 2020. Upon adoption, there was no material impact to our financial statements.
9

In December 2019, the FASB issued Accounting Standards Update (“ASU”) No. 2019-12, "Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes” (“ASU 2019-12”). ASU 2019-12 simplifies the accounting for income taxes by clarifying and amending existing guidance related to the recognition of franchise tax, the evaluation of a step up in the tax basis of goodwill, and the effects of enacted changes in tax laws or rates in the effective tax rate computation, among other clarifications. ASU 2019-12 is effective for public business entities for fiscal years beginning after December 15, 2020, including interim periods within that fiscal year, with early adoption permitted. We adopted this standard on October 1, 2021 and there was no material impact to our financial statements.
In March 2020, the FASB issued ASU No. 2020-04, "Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting" (“ASU 2020-04”). This guidance provides optional expedients and exceptions for applying GAAP to contracts, hedging relationships and other transactions affected by reference rate reform if certain criteria are met. The amendments apply only to contracts and hedging relationships that reference the London Inter Bank Offered Rate (“LIBOR”) or another reference rate expected to be discontinued due to reference rate reform. ASU 2020-04 is effective from March 12, 2020, but can be adopted prospectively from a date within an interim period subsequent to March 12, 2020. We evaluated our contracts and the optional expedients provided by ASU 2020-04. We adopted this standard on October 1, 2021 and there was no material impact to our financial statements.
Restructuring
Since November 2019, we have announced the purchase and closure of several facilities. We purchased a new facility in Kimball, Tennessee to support and enhance our investment in our Chattanooga, Tennessee large casting foundry and closed our facilities in Hammond, Indiana, Woodland, Washington and Surrey, British Columbia, Canada. We also announced the closure of our facility in Aurora, Illinois which we expect to complete substantially by the third quarter of fiscal year 2022. The majority of the activities from these facilities have been, or will be, transferred to our Kimball, Tennessee facility. Activity in accrued restructuring, reported as part of Other current liabilities, is presented below.

New Markets Tax Credit Program
On December 22, 2020, we entered into a financing transaction with Wells Fargo Community Investment Holdings, LLC (“Wells Fargo”) related to our brass foundry construction project in Decatur, Illinois under a qualified New Markets Tax Credit program (“NMTC”). The NMTC is a federal program intended to encourage capital investment in qualified lower income communities. Under the NMTC, investors claim federal income tax credits over a period of seven years in connection with qualified investments in the equity of community development entities (“CDE”s), which are privately managed investment institutions that are certified to make qualified low-income community investments, such as in our foundry project.
Under the NMTC, Wells Fargo contributed capital of $4.8 million to an investment fund and we loaned $12.2 million to the fund. Wells Fargo is entitled to the associated tax credits, which are subject to 100% recapture if we do not comply with various regulations and contractual provisions surrounding the foundry project. We have indemnified Wells Fargo for any loss or recapture of tax credits related to the transaction until the seven-year period elapses. We do not anticipate any credit recaptures will be required in connection with this arrangement.
The investment fund contributed $16.5 million cash for a 99.99% stake in a joint venture (“Sub-CDE”) with a CDE. The Sub-CDE then loaned $16.2 million to us, with the use of the loan proceeds restricted to foundry project expenditures. This transaction also includes a put/call provision under which we may be obligated or entitled to repurchase Wells Fargo’s interest in the investment fund. We believe that Wells Fargo will exercise its put option in December 2027 for nominal consideration, resulting in our becoming the sole owner of the investment fund, cancelling the related loans, and recognizing an estimated gain of $3.9 million.
We determined that the investment fund and the Sub-CDE are variable interest entities (“VIEs”) and that we are the primary beneficiary of the VIEs. The ongoing activities of the VIEs, namely collecting and remitting interest and fees and administering NMTC compliance, were contemplated in the initial design of the transaction and are not expected to
10

significantly affect economic performance throughout the life of the VIEs. Additionally, we are obligated to deliver tax benefits and provide various other guarantees to Wells Fargo and to absorb the losses of the VIEs. Wells Fargo does not have a material interest in the underlying economics of the project. Consequently, we have included the financial statements of the VIEs in our consolidated financial statements.
Intercompany transactions between us and the VIEs have been eliminated in consolidation. Wells Fargo’s contribution to the investment fund is consolidated in our financial statements within Other noncurrent liabilities as a result of its redemption features.
Direct costs associated with Wells Fargo’s capital contribution were netted against the recorded proceeds, resulting in a net cash contribution of $3.9 million. Other direct costs associated with the transaction were capitalized and are being recognized as interest expense over the seven-year tax credit period. Incremental costs to maintain the structure during the compliance period are expensed as incurred.

Note 2.    Acquisitions
Acquisition of i2O Water Ltd
On June 14, 2021, we acquired all the outstanding capital stock of i2O for $19.7 million, net of cash acquired. The purchase agreement provided for customary final adjustments, including a net working capital adjustment that was completed during the three months ended December 31, 2021, resulting in a purchase price of $19.5 million.
We have recognized the assets acquired and liabilities assumed at their estimated acquisition date fair values, with the excess of the purchase price over the estimated fair values of the identifiable net assets acquired recorded as goodwill. The accounting for the business combination is considered to be final. The results of i2O are included in our Water Management Solutions segment.
The goodwill below is attributable to the strategic opportunities and synergies that we expect to arise from the acquisition of i2O and the value of its workforce. Goodwill is nondeductible for income tax purposes. Identified intangible assets consist of customer relationships, non-compete agreements and developed technology with an estimated weighted-average useful life of approximately 12 years and trade names with an indefinite life. Values of intangible assets were determined using a discounted cash flow method.
The following is a summary of the fair values of the net assets acquired (in millions):
Assets, net of cash:
Receivables$0.5 
Inventories0.6 
Other current assets0.9

Note 3.    Revenue from Contracts with Customers
We recognize revenue when control of promised products or services is transferred to our customers, in amounts that reflect the consideration to which we expect to be entitled in exchange for those products or services. We account for a contract when it has approval and commitment from both parties, the rights of the parties are identified, the payment terms are identified, the contract has commercial substance and collectability of consideration is probable. We determine the appropriate revenue recognition for our contracts with customers by analyzing the type, terms and conditions of each contract or arrangement with a customer.
Disaggregation of Revenue
We disaggregate our revenue from contracts with customers by reportable segment (see Note 10.) and further by geographical region as we believe this best depicts how the nature, amount, timing and uncertainty of our revenue and cash flows are affected by economic factors. Geographical region represents the location of the customer.
Contract Asset and Liability Balances
Differences in the timing of revenue recognition, billing and cash collection result in customer receivables, advance payments and billings in excess of revenue recognized. Customer receivables include amounts billed and currently due from customers as well as unbilled amounts (i.e., contract assets). Amounts are billed in accordance with contractual terms and unbilled amounts arise when the timing of billing differs from the timing of revenue recognized.
Advance payments and billings in excess of revenue are recognized and recorded as deferred revenue, the majority of which we expect to receive within one year and therefore is included within Other current liabilities in the accompanying consolidated balance sheets. Deferred revenue represents contract liabilities and are recorded when customers remit cash payments in advance of our satisfaction of performance obligations under contractual arrangements. Contract liabilities are relieved and revenue is recognized when the performance obligation is satisfied.
The table below represents the balances of our customer receivables and deferred revenue.

(in millions)
Billed receivables$224.8 $213.4 
Unbilled receivables1.9 2.3

Allowance for credit losses(4.5)(3.5)
Receivables, net$222.2 $212.2 
Deferred revenue$7.6 $5.4 
Performance Obligations
A performance obligation is a promise in a contract to transfer a distinct good or service to the customer. Our performance obligations are satisfied at a point in time for sales of product or over time for our software hosting and leak detection monitoring services. Performance obligations are supported by customer contracts, which provide frameworks for the nature of the distinct products or services. We allocate the transaction price of each contract to the performance obligations on the basis of standalone selling price and recognize revenue when control of the performance obligation transfers to the customer. The transaction price is adjusted for our estimate of variable consideration which may include discounts, and rebates. To estimate variable consideration, we apply the expected value or the most likely amount method, based on whichever method most appropriately predicts the amount of consideration we expect to receive. The method applied is based typically on historical experience and known trends. We do not recognize variable consideration in the event there are uncertainties in the amount of variable consideration to be paid nor when it is probable there will be a significant reversal in the related revenue.
We exclude from the measurement of the transaction price all taxes assessed by a governmental authority. We classify shipping and handling costs, such as freight to our customers’ destinations, as a component of Cost of sales.
We have elected to use the practical expedient to not adjust the transaction price of a contract for the effects of a significant financing component if, at the inception of the contract, we expect that the period between when we transfer a product or service to a customer and when a customer remits payment will be one year or less.
12

The revenue recognized at a point in time related to the sale of our products is recognized when the obligations of the terms of our contract are satisfied, which generally occurs upon shipment when control of the product transfers to the customer.
We offer warranties that provide assurance that the products provided will function as intended and comply with any agreed-upon specifications. These cannot be purchased separately.
Costs to Obtain or Fulfill a Contract
We incur certain incremental costs to obtain a contract, which primarily relate to incremental sales commissions. Our commissions are paid based on a combination of orders and shipments, and we reserve the right to claw back any commissions in case of product returns or lost collections. As the expected benefit associated with these incremental costs is generally one year or less based on the nature of the product sold and benefits received, we have applied a practical expedient and therefore do not capitalize the related costs and expense them as incurred.

ABL Agreement. Our asset-based lending agreement (“ABL Agreement”) consists of a revolving credit facility for up to $175.0 million which includes up to $25.0 million of swing line loans and may have up to $60.0 million of letters of credit. The ABL Agreement permits us to increase the size of the credit facility by an additional $150.0 million in certain circumstances subject to adequate borrowing base availability.
Borrowings under the ABL Agreement bear interest at a floating rate equal to LIBOR plus an applicable margin range of 200 to 225 basis points, or a base rate, as defined in the ABL Agreement, plus an applicable margin range of from 100 to 125 basis points. At March 31, 2022 the applicable margin for LIBOR based loans was 200 basis points and for base rate loans was 100 basis points.
13

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) 70% of the value of eligible inventory or (ii) 85% of the net orderly liquidation value of eligible inventory, less certain reserves. Prepayments can be made at any time without penalty.
Substantially all of our United States 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 United States inventories, accounts receivable, certain cash and other related items.
The ABL Agreement terminates on July 29, 2025 and includes a commitment fee for any unused borrowing capacity of 37.5 basis points per annum. Borrowings are not subject to any financial maintenance covenants unless excess availability is less than the greater of $17.5 million or 10% of the Loan Cap as defined in the ABL Agreement. Excess availability based on March 31, 2022 data was $160.1 million, as reduced by $14.7 million of outstanding letters of credit and $0.2 million of accrued fees and expenses.
4.0% Senior Unsecured Notes. On May 28, 2021, we privately issued $450.0 million of 4.0% Senior Unsecured Notes (“4.0% Senior Notes”), which mature on June 15, 2029 and bear interest at 4.0%, paid semi-annually in June and December. We capitalized $5.5 million of financing costs which are being amortized over the term of the 4.0% Senior Notes using the effective interest method. Substantially all of our U.S. subsidiaries guarantee the 4.0% Senior Notes that are subordinate to borrowings under our ABL Agreement. Based on quoted market prices that are a Level 1 measurement, the outstanding 4.0% Senior Notes had a fair value of $426.0 million at March 31, 2022.
An indenture governing the 4.0% Senior Notes (“Indenture”) contains customary covenants and events of default, including covenants that limit our ability to incur certain debt and liens. There are no financial maintenance covenants associated with the Indenture. We believe we were in compliance with these covenants at March 31, 2022.
As set forth in the Indenture, we may redeem some or all of the 4.0% Senior Notes at any time prior to June 15, 2024 at certain “make-whole” redemption prices and on or after June 15, 2024 at specified redemption prices. Additionally, we may redeem up to 40% of the aggregate principal amount of the 4.0% Senior Notes at any time prior to June 15, 2024 with the net proceeds of specified equity offerings at specified redemption prices. Upon a change of control, we would be required to offer to purchase the 4.0% Senior Notes at a price equal to 101% of the outstanding principal amount of the 4.0% Senior Notes.
Note 6. Derivative Financial Instruments
In connection with the acquisition of Singer Valve in 2017, we loaned funds to one of our Canadian subsidiaries. Although this intercompany loan had no direct effect on our consolidated financial statements, it created exposure to currency risk for the Canadian subsidiary. To reduce this exposure, we entered into a U.S. dollar-Canadian dollar swap contract with the Canadian subsidiary and an offsetting Canadian dollar-U.S. dollar swap with a domestic bank. We did not designate these swaps as hedges and the changes in their fair value were included in earnings, offsetting the currency gains and losses associated with the intercompany loan.
The value of our currency swap contracts as of September 30, 2021 was a liability of $1.1 million, and was included in Other current liabilities. The currency swap contracts expired in February 2022.

Note 8. Stock-based Compensation Plans
We grant various forms of stock-based compensation, including market-based restricted stock units (“MRSUs”), restricted stock units, stock options and performance-based restricted stock units (“PRSUs”) under our Amended and Restated 2006 Mueller Water Products, Inc. Stock Incentive Plan (the “2006 Stock Plan”), Phantom Plan instruments under our Mueller Water Products, Inc. 2012 Phantom Plan, and Employee stock purchase plan instruments under our 2006 Employee Stock Purchase Plan.

An MRSU award represents a target number of units that may be paid out at the end of a three-year award cycle based on a calculation of our relative total shareholder return (“TSR”) performance as compared with the TSR of a selected peer group. Settlements, in our common shares, will range from zero to two times the number of MRSUs granted, depending on our TSR performance relative to that of the peer group.
15

Compensation expense attributed to MRSUs is based on the fair value of the awards on their respective grant dates, as determined using a Monte Carlo model. The assumptions used to determine the grant date fair value are indicated below.
November 30, 2021
Variables used in determining grant date fair value:
Dividend yield1.70 %
Risk-free rate0.76 %
Expected term (in years)2.83

The expected dividend yield is based on our estimated annual dividend and our stock price history at the grant date. The risk-free interest rate is based on the U.S. Treasury zero-coupon yield in effect at the grant date with a term equal to the expected term. The expected term represents the average period of time the units are expected to be outstanding.
At March 31, 2022, the outstanding Phantom Plan instruments had a fair value of $12.92 per instrument and our liability for Phantom Plan instruments was $2.1 million and is included within Other current and Other noncurrent liabilities.

Stock options generally vest ratably over three years on each anniversary date. Compensation expense attributed to stock options is based on the fair value of the awards on their respective grant dates, using a Black-Scholes model. The assumptions used to determine the grant date fair value are indicated below.
November 30, 2021
Dividend yield1.62 %
Risk-free rate1.33 %
Expected term (in years)6.00

The expected dividend yield is based on our estimated annual dividend and our stock price history at the grant date. The risk-free interest rate is based on the U.S. Treasury zero-coupon yield in effect at the grant date with a term equal to the expected term. The expected term represents the average period of time the options are expected to be outstanding.
A PRSU award consists of a number of units that may be paid out at the end of a three-year award cycle consisting of a series of annual performance periods coinciding with our fiscal years. After we establish the financial performance targets related to PRSUs for a given performance period, typically during the first quarter of that fiscal year, we consider that portion of a PRSU award to be granted. Thus, each award consists of a grant in the year of award and grants in the two following years. Settlements, in our common shares, will range from zero to two times the number of PRSUs granted, depending on our financial performance relative to the targets.
We did not issue any shares of common stock to settle PRSUs vested during the three months ended March 31, 2022; however, we issued 240,412 shares of common stock to settle PRSUs vested during the six months ended March 31, 2022. Additionally, we issued 104,380 and 235,095 shares of common stock to settle restricted stock units vested during the three and six months ended March 31, 2022, respectively. Finally, we issued no shares of common stock to settle stock options exercised during the three months ended March 31, 2022; however, we issued 24,153 shares of common stock to settle stock options exercised during the six months ended March 31, 2022.
Operating income included stock-based compensation expense of $2.5 million in each of the three months ended March 31, 2022 and 2021. Operating income included stock-based compensation expense of $5.1 million and $5.0 million during the six months ended March 31, 2022 and 2021, respectively. At March 31, 2022, there was approximately $13.3 million of unrecognized compensation expense related to stock-based compensation arrangements and there were 58,139 PRSUs that have been awarded for the 2022 performance period for which performance goal achievement cannot yet be determined.
We excluded 944,631 and 664,082 stock-based compensation instruments from the calculations of diluted earnings per share in the three months ended March 31, 2022 and 2021, respectively, and 563,299 and 447,086 for the six months ended March 31, 2022 and 2021, respectively, since their inclusion would have been antidilutive.
