NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

Note 1. Basis of Presentation

The accompanying unaudited Condensed Consolidated Financial Statements of Kimball International, Inc. (the “Company,” “Kimball International,” “we,” “us,” or “our”) have been prepared in accordance with the instructions to Form 10-Q. As such, certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) have been condensed or omitted, although we believe that the disclosures are adequate to make the information presented not misleading. Intercompany transactions and balances have been eliminated. Management believes the financial statements include all adjustments (consisting only of normal recurring adjustments) considered necessary to present fairly the financial statements for the interim periods. The results of operations for the interim periods shown in this report are not necessarily indicative of results for any future interim period or for the entire fiscal year. It is suggested that these financial statements be read in conjunction with the financial statements and the notes thereto included in our latest annual report on Form 10-K.

Prior Period Reclassifications

Our prior period financial statements were recast for the full retrospective adoption of guidance on the recognition of revenue from contracts with customers. Certain prior period amounts on the Condensed Consolidated Statements of Cash Flows have also been recast to incorporate restricted cash flows and restricted cash balances, as a result of the retrospective adoption of new accounting guidance.

Note 2. Recent Accounting Pronouncements and Supplemental Information

Recently Adopted Accounting Pronouncements:

In August 2018, the Securities and Exchange Commission adopted disclosure and simplification amendments which update certain disclosure requirements that were redundant, duplicative, overlapping, outdated, or superseded. The amendments require a shareowners’ equity statement provided in interim financial statements or in a note. The adoption resulted in the addition of an interim Condensed Consolidated Statements of Shareowners’ Equity.

In June 2018, the Financial Accounting Standards Board (“FASB”) issued guidance to improve the accounting for and to reduce the cost and complexity of share-based payments to nonemployees for goods and services. The guidance is effective for our first quarter of fiscal year 2020 with early adoption permitted, but it may not be adopted earlier than our adoption of the new revenue standard. We early adopted the guidance in our first quarter of fiscal year 2019 in advance of the October 2018 retirement of our Chief Executive Officer and Chairman of our Board of Directors, who will have stock compensation awards vesting after his retirement. The adoption did not have a material effect on our first quarter of fiscal year 2019 condensed consolidated financial statements.

In May 2017, the FASB issued guidance that clarifies when changes to the terms or conditions of a share-based payment award must be accounted for as modifications. The guidance was adopted during our first quarter of fiscal year 2019 and was applied prospectively to awards modified on or after the adoption date. The adoption of the guidance did not have a material effect on our condensed consolidated financial statements.

In March 2017, the FASB issued guidance that requires employers that present a measure of operating income in their statement of income to include only the service cost component of net periodic benefit cost in operating expenses, which will impact the presentation of our postemployment benefit plan. Employers are required to present all other components of net benefit cost separate from the service costs and disclose the line item in which the components of net benefit cost other than the service cost are included. Due to the immaterial amounts in prior periods we did not apply the rule retrospectively. The guidance was adopted during our first quarter of fiscal year 2019 and did not have a material effect on our condensed consolidated financial statements.

In February 2017, the FASB issued guidance that clarifies the scope of guidance on nonfinancial asset derecognition as well as the accounting for partial sales of nonfinancial assets. This new guidance is meant to clarify the scope of the original guidance that was issued in connection with the guidance relating to the recognition of revenue from contracts with customers, as defined below, which addresses recognizing gains and losses from the transfer of nonfinancial assets in contracts with noncustomers. The guidance was adopted during our first quarter of fiscal year 2019 concurrently with the adoption of the guidance on recognition of

revenue from contracts with customers. The adoption of this guidance did not have a material impact on our condensed consolidated financial statements.

In November 2016, the FASB issued guidance which requires an entity to include in their cash and cash equivalent balances in the statement of cash flows those amounts that are deemed to be restricted cash and restricted cash equivalents. The guidance was adopted during our first quarter of fiscal year 2019 and was applied retrospectively to each prior reporting period. The guidance resulted in certain prior period amounts being reclassified to conform with the current period presentation, including the addition of restricted cash to cash and cash equivalents on the Condensed Consolidated Statements of Cash Flows.

In January 2016, the FASB issued guidance which is intended to improve the recognition and measurement of financial instruments. The guidance revises an entity’s accounting related to the classification and measurement of investments in equity securities and the presentation of certain fair value changes for financial liabilities measured at fair value. The guidance also amends certain disclosure requirements associated with the fair value of financial instruments. The guidance was adopted during our first quarter of fiscal year 2019 and did not have a material effect on our condensed consolidated financial statements.

In May 2014, the FASB issued guidance on the recognition of revenue from contracts with customers. The core principle of the guidance is that a company should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration which the company expects to receive in exchange for those goods or services. To achieve this core principle, the guidance provides a five-step analysis of transactions to determine when and how revenue is recognized. The guidance addresses several areas including transfer of control, contracts with multiple performance obligations, and costs to obtain and fulfill contracts. The guidance also requires additional disclosure about the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments and changes in judgments and assets recognized from costs incurred to obtain or fulfill a contract. In July 2015, the FASB decided to defer the effective date for this new revenue standard by one year, which made the guidance effective for our first quarter of fiscal year 2019 financial statements using either of two acceptable adoption methods: (i) full retrospective adoption to each prior reporting period presented with the option to elect certain practical expedients; or (ii) adoption with the cumulative effect of initially applying the guidance recognized at the date of initial application and providing certain additional disclosures. In March 2016, the FASB issued additional guidance which further clarified assessing whether an entity is a principal or an agent in a revenue transaction, and impacted whether an entity reports revenue on a gross or net basis; in April 2016, the FASB issued additional guidance that addressed identifying performance obligations and implementing licensing guidance; and in May 2016, the FASB issued additional guidance that clarified collectability, noncash consideration, and other transition issues. The amendments had the same effective date and transition requirements as the new revenue standard. We adopted the standard at the beginning of fiscal year 2019 using the full retrospective approach which required that we recast prior year comparative periods to provide comparable financial reporting for all reported fiscal years. All changes required by the new standard, including accounting policies, controls, and disclosures, have been identified and implemented as of the beginning of fiscal 2019. We applied the transition practical expedient related to remaining performance obligations for reporting periods presented before the date of initial application. See Note 4 - Revenue in the Notes to Condensed Consolidated Financial Statements for more information on revenue recognition.

Recently Issued Accounting Pronouncements Not Yet Adopted:

In August 2018, the FASB issued guidance on a customer’s accounting for implementation, set-up, and other upfront costs incurred in a cloud computing arrangement that is hosted by the vendor. Under the new guidance, customers will apply the same criteria for capitalizing implementation costs as they would for an arrangement that has a software license. The guidance is effective for our first quarter of fiscal year 2021 with early adoption permitted. Entities can choose to adopt the guidance prospectively to eligible costs incurred on or after the date this guidance is first applied or retrospectively. We have not yet determined the effect of this guidance on our condensed consolidated financial statements.

In August 2018, the FASB issued guidance to add, remove, and clarify disclosure requirements related to defined pension benefit and other postretirement plans. The guidance is effective for our first quarter of fiscal year 2021 with early adoption permitted and should be applied retrospectively. We have not yet determined the effect of this guidance on our condensed consolidated financial statements.

In August 2018, the FASB issued guidance which changes the fair value measurement disclosure requirements. The guidance modifies and removes certain disclosures related to the fair value hierarchy, and adds new disclosure requirements such as disclosing the changes in unrealized gains and losses included in other comprehensive income for recurring Level 3 fair value measurements and disclosing the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements. The guidance is effective for our first quarter of fiscal year 2021 with early adoption permitted and should

be applied retrospectively except for certain disclosures. We have not yet determined the effect of this guidance on our condensed consolidated financial statements.

In March 2017, the FASB issued guidance that will shorten the amortization period for certain callable debt securities held at a premium to the earliest call date. This guidance does not require an accounting change for securities held at a discount. This guidance is to be applied on a modified retrospective basis, with a cumulative-effect adjustment directly to retained earnings as of the beginning of the period of adoption. The guidance is effective for our first quarter of fiscal year 2020 with early adoption permitted. We have not yet determined the effect of this guidance on our condensed consolidated financial statements.

In June 2016, the FASB issued guidance on the measurement of credit losses on financial instruments. Under the guidance, an entity recognizes as an allowance its estimate of expected credit losses, which the FASB believes will result in more timely recognition of such losses. The guidance is also intended to reduce the complexity by decreasing the number of credit impairment models that entities use to account for debt instruments. The guidance is effective for our first quarter of fiscal year 2021 with early adoption in our fiscal year 2020 permitted. We have not yet determined the effect of this guidance on our condensed consolidated financial statements.

In February 2016, the FASB issued guidance that revises the accounting for leases. The guidance is intended to improve financial reporting of leasing transactions by requiring lessees to record right-of-use assets and corresponding lease liabilities on the balance sheet. Leases will continue to be classified as either operating or finance leases, with the classification affecting the pattern of expense recognition in the statement of income. The guidance will also require additional disclosures to help investors and other financial statement users better understand the amount, timing, and uncertainty of cash flows arising from leases. In January 2018, the FASB issued additional guidance for land easements which permits entities to forgo the evaluation of existing land easement arrangements to determine if they contain a lease. New land easement arrangements, or modifications to existing arrangements, after the adoption of the lease standard will be evaluated to determine if they meet the definition of a lease. In July 2018, the FASB amended the new standard to clarify certain aspects of the guidance, and also issued another standard that allows the option to apply the provisions of the leasing standard at the adoption date instead of at the earliest comparative period in the condensed consolidated financial statements. The guidance is effective for our first quarter of fiscal year 2020 with early adoption permitted. We expect to utilize the option to not retrospectively adjust prior comparative periods. We are currently evaluating the impact of this guidance but have not yet determined the effect on our condensed consolidated financial statements.

Goodwill and Other Intangible Assets:

Goodwill represents the difference between the purchase price and the related underlying tangible and intangible net asset fair values resulting from business acquisitions. Goodwill is assigned to and the fair value is tested at the reporting unit level. Annually, or if conditions indicate an earlier review is necessary, we may assess qualitative factors to determine if it is more likely than not that the fair value is less than its carrying amount. We also have the option to bypass the qualitative assessment and proceed directly to performing the quantitative goodwill impairment test which compares the carrying value of the reporting unit to the reporting unit’s fair value to identify impairment. Under the quantitative assessment, if the fair value of the reporting unit is less than the carrying value, goodwill is written down to its fair value. The fair value is established primarily using a discounted cash flow analysis and secondarily a market approach utilizing current industry information. The calculation of the fair value of the reporting unit considers current market conditions existing at the assessment date. During the three months ended September 30, 2018 , no goodwill impairment was recognized.

During fiscal year 2018, we recorded $8.8 million and $10.7 million , respectively, in goodwill and other intangible assets from the acquisition of D’style, Inc. See Note 3 - Acquisition in the Notes to Condensed Consolidated Financial Statements for more information on this acquisition.

Other Intangible Assets reported on the Condensed Consolidated Balance Sheets consist of capitalized software, product rights, customer relationships, trade names, and non-compete agreements. Intangible assets are reviewed for impairment when events or circumstances indicate that the carrying value may not be recoverable over the remaining lives of the assets. A summary of intangible assets subject to amortization is as follows:

	September 30, 2018												June 30, 2018
(Amounts in Thousands)	Cost				Accumulated Amortization				Net Value				Cost				Accumulated Amortization				Net Value
Capitalized Software	$	38,658			$	36,134			$	2,524			$	38,482			$	35,922			$	2,560
Product Rights	162				162				—				162				162				—
Customer Relationships	7,050				574				6,476				7,050				422				6,628
Trade Names	3,570				327				3,243				3,570				238				3,332
Non-Compete Agreements	100				18				82				100				13				87
Other Intangible Assets	$	49,540			$	37,215			$	12,325			$	49,364			$	36,757			$	12,607

Amortization expense related to intangible assets was, in thousands, $475 and $295 during the three months ended September 30, 2018 and 2017 , respectively. Amortization expense in future periods is expected to be, in thousands, $1,435 for the remainder of fiscal year 2019, and $1,997 , $1,613 , $1,272 , and $1,044 in the four years ending June 30, 2023, and $4,964 thereafter. The estimated useful life of internal-use software ranges from 3 to 10 years . The amortization period for customer relationship intangible assets is 20 years . The estimated useful life of trade names is 10 years . The estimated useful life of non-compete agreements is 5 years .

Internal-use software is stated at cost less accumulated amortization and is amortized using the straight-line method. During the software application development stage, capitalized costs include external consulting costs, cost of software licenses, and internal payroll and payroll-related costs for employees who are directly associated with a software project. Upgrades and enhancements are capitalized if they result in added functionality which enable the software to perform tasks it was previously incapable of performing. Software maintenance, training, data conversion, and business process re-engineering costs are expensed in the period in which they are incurred. 

Trade names, non-compete agreements, and product rights to produce and sell certain products are amortized on a straight-line basis over their estimated useful lives. Capitalized customer relationships are amortized on estimated attrition rate of customers. We have no intangible assets with indefinite useful lives which are not subject to amortization.

Notes Receivable and Trade Accounts Receivable:

Notes receivable and trade accounts receivable are recorded per the terms of the agreement or sale, and accrued interest is recognized when earned. We determine on a case-by-case basis the cessation of accruing interest, the resumption of accruing interest, the method of recording payments received on nonaccrual receivables, and the delinquency status for our limited number of notes receivable.

Our policy for estimating the allowance for credit losses on trade accounts receivable and notes receivable includes analysis of such items as aging, credit worthiness, payment history, and historical bad debt experience. Management uses these specific analyses in conjunction with an evaluation of the general economic and market conditions to determine the final allowance for credit losses on the trade accounts receivable and notes receivable. Trade accounts receivable and notes receivable are written off after exhaustive collection efforts occur and the receivable is deemed uncollectible. Our limited amount of notes receivable allows management to monitor the risks, credit quality indicators, collectability, and probability of impairment on an individual basis. Adjustments to the allowance for credit losses are recorded in selling and administrative expenses. Customary terms require payment within 30 days , with terms beyond 30 days being considered extended.

Non-operating Income (Expense), net:

The non-operating income (expense), net line item includes the impact of such items as fair value adjustments on Supplemental Employee Retirement Plan (“SERP”) investments, amortization of actuarial income, foreign currency rate movements, investment gain or loss, non-production rent income, bank charges, and other miscellaneous non-operating income and expense items that are not directly related to operations. The gain or loss on SERP investments is offset by a change in the SERP liability that is recognized in selling and administrative expenses.

Components of the Non-operating income (expense), net line, were:

Note 3. Acquisition

On November 6, 2017, we acquired certain assets of D’style, Inc. (“D’style”) and all of the capital stock of Diseños de Estilo S.A. de C.V. headquartered in Tijuana, Mexico, a member of the D’style group which manufactures exclusively for D’style, strengthening our North American manufacturing footprint. The purchase price allocation did not change from the amounts disclosed in our Annual Report on Form 10-K for the fiscal year ended June 30, 2018, and is final as of September 30, 2018. The portion of the earn-out related to fiscal year 2018 performance totaling $0.4 million was paid during our quarter ended September 30, 2018 which reduced the fair value earn-out liability as of June 30, 2018 from $1.1 million to $0.7 million as of September 30, 2018. The remaining earn-out is contingent based upon fiscal year 2019 D’style, Inc. operating income compared to a predetermined target.

Note 4. Revenue

We adopted new accounting guidance on the recognition of revenue from contracts with customers at the beginning of fiscal year 2019 using the full retrospective approach and adjusted fiscal year 2018 to provide comparable financial reporting for all reported fiscal years. The primary impact of the new revenue standard was a reclassification of certain items on the statement of income. For contracts involving products that are sold directly to end customers, fees paid to dealer agents for facilitating the sale and performing certain services are recognized as either cost of sales or selling expense rather than being netted against revenue. In addition, any commissions or fees paid to third-party purchasing organizations are recognized as a selling expense rather than being netted against revenue. The result of these changes was increases in net sales, cost of sales, and selling expenses. On a net basis these changes had no impact to operating income dollars but did reduce operating income as a percent of net sales. The new standard also required several less significant changes including classifying the reserve for returns and allowance as a liability rather than a contra-receivable, recognizing a recovery asset for potential product returns, and capitalizing costs to obtain sales contracts. There was no cumulative effect of adopting the standard at the date of initial application in retained earnings.

The following tables present the effects of the adoption of the new standard on prior period financial statements:

Performance Obligations

Revenue is measured as the amount of consideration we expect to receive in exchange for transferring distinct goods or providing services to customers. Our revenue consists substantially of product sales, and is reported net of sales discounts, rebates, incentives, returns, and other allowances offered to customers. We recognize revenue when performance obligations under the terms of contracts with our customers are satisfied, which occurs when control passes to a customer to enable them to direct the use of and obtain benefit from a product. This typically occurs when a customer obtains legal title, obtains the risks and rewards of ownership, has received the goods according to the contractual shipping terms either at the shipping point or destination, and is obligated to pay for the product. Customary terms require payment within 30 days , and for certain customers, deposits may be required in advance of shipment.

We sell products both to independent dealers and directly to end customers. Sales to independent dealers typically include products only, as the independent dealer provides additional value-added services to end customers. Direct sales to end customers include products and may include related services such as installation and design services. These services are distinct from the delivered products within the context of the contract, and therefore revenue is recognized for products, installation, and design on a discrete basis. The performance of services may be outsourced to independent dealers or other third parties, but we typically retain the primary responsibility for performance of the services when selling directly to end customers. For services, revenue is recognized when the service is performed and we have an enforceable right to payment. Service revenue does not represent a significant portion of our total sales.

We provide an assurance-type warranty that guarantees our product complies with agreed-upon specifications. This warranty is not sold separately and does not convey any additional services to the customer; therefore, our warranty is not considered a separate performance obligation. We estimate the costs that may be incurred under warranties and record a liability at the time product revenue is recognized. See Note 8 - Commitments and Contingent Liabilities in the Notes to Condensed Consolidated Financial Statements for additional information on warranty obligations.

Disaggregation of Revenue

The following table provides information about revenue by vertical market:

We report revenue under a single aggregated reportable segment consisting of three operating segments which have similar products and services in nature, utilize similar production and distribution processes, and share similar long-term economic characteristics.

Contract Balances

We have contract assets reported as Receivables in the Condensed Consolidated Balance Sheets, which represent the amount of consideration to which we are entitled in exchange for the goods or services sold to our customers, net of allowances for doubtful accounts. Receivables are recorded when the right to consideration from the customer becomes unconditional, which is generally upon billing or upon satisfaction of a performance obligation, whichever is earlier. During the three months ended September 30, 2018 and 2017, impairment losses on doubtful accounts receivable, where collectability is not reasonably assured, were $0.5 million and $0.2 million , respectively.

We also receive deposits from certain customers before revenue is recognized, resulting in the recognition of a contract liability reported as Customer Deposits in the Condensed Consolidated Balance Sheets. Changes in the customer deposits during the three months ended September 30, 2018 are as follows:

Customer deposits are typically utilized within a year of the receipt of the deposit. The amount of revenue recognized during the three months ended September 30, 2018 that was included in the June 30, 2018 customer deposit balance was $16.7 million . The amount of revenue recognized during the three months ended September 30, 2017 that was included in the June 30, 2017 customer deposit balance was $15.0 million .

Additionally, we have contract assets representing funds paid to certain independent dealers in exchange for their multi-year commitment to market and sell our product. These incremental costs of obtaining contracts are capitalized to the extent we expect to recover them, with $0.3 million reported in Prepaid Expenses and Other Current Assets and $0.3 million reported in Other Assets in the Condensed Consolidated Balance Sheets as of both September 30, 2018 and June 30, 2018. The capitalized costs are amortized over the term of the contract. Amortization expense recognized in Selling and Administrative Expenses was $0.1 million for both the three months ended September 30, 2018 and 2017.

Significant Judgments

We use significant judgment in estimating the reduction in net sales driven by customer rebate and incentive programs. Judgments primarily include an estimate of the most likely sales levels to be achieved and the corresponding rebate and incentive amounts expected to be earned by dealers and salespersons. In the three months ended September 30, 2018 and 2017, we had an immaterial amount of adjustments to estimates for cumulative growth rebates and incentives that related to the preceding fiscal years. We also use judgment in estimating a reserve for returns and allowances recorded at the time of the sale, resulting in a reduction of revenue, based on estimated product returns and price concessions.

Accounting Policies and Practical Expedients Elected

For shipping and handling activities, we are applying an accounting policy election which allows an entity to account for shipping and handling activities as fulfillment activities rather than a promised good or service when the activities are performed, even if those activities are performed after the control of the good has been transferred to the customer. Therefore, we expense shipping and handling costs at the time revenue is recognized. We classify shipping and handling expenses in Cost of Sales in the Condensed Consolidated Statements of Income.

We are also applying an accounting policy election which allows an entity to exclude from revenue any amounts collected from customers on behalf of third parties, such as sales taxes and other similar taxes we collect concurrent with revenue-producing activities. Therefore, we present revenue net of sales taxes and similar revenue-based taxes.

For incremental costs of obtaining a contract, we elected a practical expedient which permits an entity to recognize incremental costs to obtain a contract as an expense when incurred if the amortization period is less than one year. This election had an immaterial effect on our financial statements.

For significant financing components, we elected a practical expedient which allows an entity to recognize the promised amount of consideration without adjusting for the time value of money if the contract has a duration of one year or less, or if the reason

the contract extended beyond one year is because the timing of delivery of the product is at the customer’s discretion. As our contracts typically are less than one year in length and do not have significant financing components, we have not presented revenue on a present value basis.

Note 5. Income Taxes

On December 22, 2017, the Tax Cuts and Jobs Act (“Tax Act”) was signed into law. The Tax Act reduced federal corporate income tax rates effective January 1, 2018 and changed numerous other provisions. Because Kimball International has a June 30 fiscal year-end, the lower corporate federal income tax rate was phased in, resulting in a blended U.S. federal statutory tax rate of 28.1%  for our fiscal year ended June 30, 2018, and  21%  for fiscal year 2019. Prior to the effective date of the Tax Act, the U.S. federal statutory tax rate was 35% .

In determining the quarterly provision for income taxes, we use an estimated annual effective tax rate which is based on expected annual income, statutory tax rates, and available tax planning opportunities in the various jurisdictions in which we operate. Unusual or infrequently occurring items are separately recognized in the quarter in which they occur. Our effective tax rate of 24.4% for the three months ended September 30, 2018 was lower than the effective tax rate of 33.4% for the three months ended September 30, 2017 , primarily due to the benefits of the Tax Act. Our effective tax rate for the three months ended September 30, 2018 approximated the combined federal and state statutory tax rate, and our effective tax rate for the three months ended September 30, 2017 was lower than the combined federal and state statutory tax rate primarily due to excess tax benefits from stock award vesting.

For interim reporting, LIFO inventories are computed based on quantities as of the end of the quarter and interim changes in price levels. Changes in quantities and price levels are reflected in the interim financial statements in the period in which they occur, except in cases where LIFO inventory liquidations are expected to be reinstated by fiscal year end. The earnings impact of LIFO inventory liquidations during the three month periods ended September 30, 2018 and 2017 was immaterial.

The following reclassifications were made from Accumulated Other Comprehensive Income to the Condensed Consolidated Statements of Income:

Amounts in parentheses indicate reductions to income.

(2) See Note 13 - Postemployment Benefits in the Notes to Condensed Consolidated Financial Statements for further information on postemployment benefit plans.

Note 8. Commitments and Contingent Liabilities

Guarantees:

Standby letters of credit were issued to lessors and insurance institutions and can only be drawn upon in the event of our failure to pay our obligations to a beneficiary. As of September 30, 2018 , we had a maximum financial exposure from unused standby letters of credit totaling $1.4 million .

We are periodically required to provide performance bonds in order to conduct business with certain customers. The bonds are required to provide assurances to customers that the products and services they have purchased will be installed and/or provided properly and without damage to their facilities. We are ultimately liable for claims that may occur against the performance bonds. We had a maximum financial exposure from one performance bond totaling $0.5 million as of September 30, 2018 .

We are not aware of circumstances that would require us to perform under these arrangements and believe that the resolution of any claims that might arise in the future, either individually or in the aggregate, would not materially affect our condensed consolidated financial statements. Accordingly, no liability has been recorded as of September 30, 2018 with respect to the standby letters of credit or performance bond. We also enter into commercial letters of credit to facilitate payments to vendors and from customers.

Product Warranties:

We provide an assurance-type warranty that guarantees our product complies with agreed-upon specifications. This warranty is not sold separately and does not convey any additional services to the customer. We estimate product warranty liability at the time of sale based on historical repair or replacement cost trends in conjunction with the length of the warranty offered. Management refines the warranty liability periodically based on changes in historical cost trends and in certain cases where specific warranty issues become known.
