Operating assets and liabilities are recognized at commencement date based on the present value of operationsthe lease payments over the lease term. As most of our leases do not provide an implicit rate, we use our incremental borrowing rate based on the information available at commencement date in determining the present value of lease payments. We use the implicit rate when readily determinable. Lease terms may include options to extend or terminate the lease when it is reasonably certain that we will exercise that option. Lease expense for lease payments is recognized on a straight-line basis over the lease term.

Lease and non-lease components are generally accounted for separately for real estate leases. For non-real estate leases, we account for the nine months ended December 30, 2018 are not necessarily indicative of the results that may be expected for the full year.

Our revenue arrangements generally consist of a single performance obligation to transfer promised goods or services. As a result, the application of ASU 2014-09 had no impact on our financial statement line items as compared with the guidance that was in effect before the change. Accordingly, the impact of adopting the standard resulted in no adjustment to accumulated retained earnings.

Net sales include products and shipping charges, net of estimates for product returns and any related sales rebates. Revenue is measured as the amount of consideration we expect to receive in exchange for transferring products. All revenue is recognized when we satisfy our performance obligations under the contract. Our criteria for recording revenue is consistent between our operating segments and types of products sold. We recognize revenue upon transfer of control of the promised products to the customer, with revenue recognized at the point in time the customer obtains control of the products. In arrangements where product is shipped directly from the vendor to our customer, we act as the principal in the transaction as we direct the other party to provide the product to our customer on our behalf, take inventory risk, establish the selling price, and are exposed to credit risk for the collection of the invoiced amount. If there were circumstances where we were to manufacture products for customers that were unique to their specifications and we would be prohibited by contract to use the product for any alternate use, we would recognize revenue over time if all criteria were met. We have made a policy election to treat shipping costs for FOB shipping point sales as fulfillment costs. As such, we recognize revenue for all shipping charges, if applicable, at the same time we recognize revenue on the products delivered. We estimate product returns based on historical return rates. Using probability assessments, we estimate sales rebates expected to be paid over the term of the contract. The majority of our contracts have a single performance obligation and are short term in nature. Sales taxes that are collected from customers and remitted to governmental authorities are accounted for on a net basis and therefore are excluded from net sales. We offer certain customers cash discounts and volume rebates as sales incentives. The discounts and volume rebates are recorded as a reduction

in sales at the time revenue is recognized in an amount estimated based on historical experience and contractual obligations. We periodically review the assumptions underlying our estimates of discounts and volume rebates and adjustsadjust revenues accordingly.

Basic earnings per share (“EPS”) are computed by dividing net earnings by the weighted-average number of common shares outstanding. Diluted EPS includes the dilutive impact of incremental shares assumed to be issued as performance units and restricted stock. Basic and diluted EPS were calculated using the following:

We have in place an interest rate swap agreement to manage the risk associated with a portion of our variable-rate long-term debt. We do not utilize derivative instruments for speculative purposes. The interest rate swap involves the exchange of fixed-rate and variable-rate payments without the exchange of the underlying notional amount on which the interest payments are calculated. The swap agreement will terminate on December 23, 2020. The notional amount of the swap agreement was $40 million from September 1, 2017 through August 31, 2018, and is currently $30 million from September 1, 2018 through August 31, 2019 and reduces to $20 million from September 1, 2019 through December 23, 2020. We have designated this swap as a cash flow hedge and have determined that it qualifies for hedge accounting treatment. For so long as the hedge is effective, changes in fair value of the cash flow hedge are recorded in other comprehensive income (net of tax) until income or loss from the cash flows of the hedged item is realized.

For both the three and nine months ended DecemberJune 30, 2018,2019, we recorded $0.2 million in other comprehensive income related to unrealized losses (net of tax) on the cash flow hedge described above. For the three and nine months ended December 31, 2017July 1, 2018, we recorded $0.1 milliona nominal amount in other comprehensive income related to unrealized gains (net of tax) on the cash flow hedge. Included in other long-term assets on our condensed consolidated balance sheet was $0.6$0.2 million as of DecemberJune 30, 20182019 and $0.8$0.4 million as of April 1, 2018March 31, 2019 related to the cash flow hedge. Unrealized gains and losses will be reflected in net income when the related cash flows or hedged transactions occur and offset the related performance of the hedged item.

By their nature, derivative instruments are subject to market risk. Derivative instruments are also subject to credit risk associated with counterparties to the derivative contracts. Credit risk associated with derivatives is measured based on the replacement cost should the counterparty with a contract in a gain position to us fail to perform under the terms of the contract. We do not anticipate nonperformance by the counterparty.

Our financial assets and liabilities are measured at fair value at the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date (exit price). We classify the inputs used to measure fair value into the following hierarchy:

Our financial assets that are measured at fair value on a recurring basis are an interest rate swap and assets held in a deferred compensation retirement plan. Both of these assets are classified as other long-term assets on our balance sheet, with the portion of the deferred compensation retirement plan assets expected to be paid within twelve months reclassified to current assets. The fair value of the interest rate swap is determined by the respective counterparties based on interest rate changes. Interest rate swaps are valued based on observable interest rate yield curves for similar instruments. The deferred compensation plan assets relate to contributions made to a non-qualified compensation plan, established in fiscal 2017, on behalf of certain employees who are classified as “highly compensated employees” as determined by IRS guidelines. The assets are part of a rabbi trust and the funds are held in mutual funds. The fair value of the deferred compensation is based on the quoted market prices for the mutual funds at the end of the period.

The following table summarizestables summarize the balances of assets measured at fair value on a recurring basis as of DecemberJune 30, 20182019 and April 1, 2018.March 31, 2019.

We are subject to U.S. federal income tax as well as income tax of multiple state jurisdictions. The tax years prior to our fiscal year ended April 3, 2016 are closed to examination by the Internal Revenue Service, and with few exceptions, state and local

income tax jurisdictions. Our effective tax rate for the ninethree months ended DecemberJune 30, 20182019 was 26.8%.26.3% and was 27.3% for the three months ended July 1, 2018. The effective tax rate is impacted by projected levels of annual taxable income, permanent items, and state taxes.

No significant changes to identifiable assets by segment occurred during the ninethree months ended DecemberJune 30, 2018.2019.

We focus on total profitability dollars when evaluating our financial results as opposed to profitability as a percentage of sales, as sales dollars tend to fluctuate, particularly in our Industrial and Water Treatment segments, as raw material costs rise and fall. The costs for certain of our raw materials can rise or fall rapidly, causing fluctuations in gross profit as a percentage of sales.

Results of Operations

Our effective income tax rate was 26.2%26.3% for the three months ended DecemberJune 30, 2018.2019. Our effective tax rate for the three months ended December 31, 2017July 1, 2018 was not meaningful as we recorded a $13.2 million one-time income tax benefit during the period as a result of the U.S. Tax Cuts and Jobs Act of 2017 which was signed into law in December 2017. The effective tax rate is impacted by projected levels of annual taxable income, permanent items, and state taxes.

We expect our cash balances and funds available under our credit facility, discussed below, along with cash flows generated from operations, will be sufficient to fund the cash requirements of our ongoing operations for the foreseeable future.

We were partyOur Board of Directors has authorized the repurchase of up to a credit agreement (the “Prior Credit Agreement”) with U.S. Bank National Association (“U.S. Bank”) as Sole Lead Arranger and Sole Book Runner and other lenders from time to time party thereto (collectively, the “Prior Lenders”), whereby U.S. Bank was also serving as Administrative Agent. The Prior Credit Agreement provided us with senior secured credit facilities totaling $165.0 million, consisting of a $100.0 million senior secured term loan credit facility and a $65.0 million senior secured revolving loan credit facility. The term loan facility required mandatory quarterly repayments, with the balance due at maturity. The revolving loan facility included a letter of credit subfacility in the amount of $5.0 million and a swingline subfacility in the amount of $8.0 million. The Prior Credit Agreement was scheduled to terminate on December 23, 2020 and the underlying credit facility was secured by substantially all800,000 shares of our personal property assetsoutstanding common stock, including an increase of 500,000 shares in February 2019. The shares may be purchased on the open market or in privately negotiated transactions subject to applicable securities laws and thoseregulations. The primary objective of the share repurchase program is to offset the impact of dilution from issuances relating to employee and director equity grants and our subsidiaries. Borrowingsemployee stock purchase program. During the first quarter of fiscal 2020, we repurchased 47,136 shares of common stock with an aggregate purchase price of $1.8 million. No shares were repurchased during the first quarter of fiscal 2019. As of June 30, 2019, 457,244 shares remained available for purchase under the Prior Credit Agreement bore interest at a variable rate per annum equal to one of the following, plus, in both cases, an applicable margin based upon our leverage ratio: (a) LIBOR for an interest period of one, two, three or six months as selected by us, reset at the end of the selected interest period, or (b) a base rate determined by reference to the highest of (1) U.S. Bank’s prime rate, (2) the Federal Funds Effective Rate plus 0.5%, or (3) one-month LIBOR for U.S. dollars plus 1.0%. The LIBOR margin was 1.125%, 1.25% or 1.5%, depending on our leverage ratio. The base rate margin was either 0.125%, 0.25% or 0.5%, depending on our leverage ratio.program

On November 30, 2018, we entered intoWe are party to an amended and restated credit agreement (the “Credit Agreement”) with U.S. Bank National Association (“U.S. Bank”) as Sole Lead Arranger and Sole Book Runner, and other lenders from time to time party thereto (collectively, the “Lenders”), whereby U.S. Bank is also serving as Administrative Agent. The Credit Agreement refinanced the term and revolving loans under the Prior Credit Agreement and provides us with senior secured revolving credit facilities (the “Revolving Loan Facility”) totaling $150.0 million. The Revolving Loan Facility includes a $5.0 million letter of credit subfacility and $15.0 million swingline subfacility. The Revolving Loan Facility has a five-year maturity date, maturing on November 30, 2023. The Revolving Loan Facility is secured by substantially all of our personal property assets and those of our subsidiaries.

Borrowings under the Revolving Loan Facility bear interest at a rate per annum equal to one of the following, plus, in both cases, an applicable margin based upon our leverage ratio: (a) LIBOR for an interest period of one, two, three or six months as selected by us, reset at the end of the selected interest period, or (b) a base rate determined by reference to the highest of (1) U. S. Bank’s prime rate, (2) the Federal Funds Effective Rate plus 0.5%, or (3) one-month LIBOR for U.S. dollars plus 1.0%. The

In addition to paying interest on the outstanding principal under the Revolving Loan Facility, we are required to pay a commitment fee on the unutilized commitments thereunder. The commitment fee is between 0.15% - 0.25%, depending on our leverage ratio.

Debt issuance costs of $0.2 million paid to the lenders in connection with the Credit Agreement, as well as unamortized debt issuance costs of $0.3 million paid in connection with the Prior Credit Agreement, are reflected as a reduction of debt and will bebeing amortized as interest expense over the term of the Revolving Loan Facility.Credit Agreement. As of June 30, 2019, the unamortized balance of these costs was $0.4 million, and is reflected as a reduction of debt on our balance sheet.

The Credit Agreement requires us to maintain (a) a minimum fixed charge coverage ratio of 1.15 to 1.00 and (b) a maximum total cash flow leverage ratio of 3.0 to 1.0. The Credit Agreement also contains other customary affirmative and negative covenants, including covenants that restrict our ability to incur additional indebtedness, dispose of significant assets, make certain investments, including any acquisitions other than permitted acquisitions, make certain payments, enter into sale and leaseback transactions, grant liens on our assets or rate management transactions, subject to certain limitations. We are permitted to make distributions, pay dividends and repurchase shares so long as no default or event of default exists or would exist as a result thereof. We were in compliance with all covenants of the Credit Agreement as of June 30, 2019.

The Credit Agreement contains customary events of default, including failure to comply with covenants in the Credit Agreement and other loan documents, cross default to other material indebtedness, failure by us to pay or discharge material judgments, bankruptcy, and change of control. The occurrence of an event of default would permit the lenders to terminate their commitments and accelerate loans under the Credit Facility.
