U.S. and Canadian Borrowers Credit Facility

For the company's U.S. and Canadian Borrowers, the Credit Agreement provides for an asset-based-lending senior secured revolving credit facility which is secured by substantially all the company’s U.S. and Canadian assets, other than real estate. The Credit Agreement provides the company and the other Borrowers with a credit facility in an aggregate principal amount of

$100,000,000, subject to availability based on a borrowing base formula, under a senior secured revolving credit, letter of credit

and swing line loan facility (the “U.S. and Canadian Credit Facility”). Up to $25,000,000 of the U.S. and Canadian Credit Facility will be available for issuance of letters of credit. The aggregate principal amount of the U.S. and Canadian Credit Facility may be increased by up to $25,000,000 to the extent requested by the company and agreed to by any Lender or new financial institution approved by the Administrative Agent.

The aggregate borrowing availability under the U.S. and Canadian Credit Facility is determined based on a borrowing base formula. The aggregate usage under the U.S. and Canadian Credit Facility may not exceed an amount equal to the sum of (a) 85% of eligible U.S. accounts receivable plus (b) the lesser of (i) 70% of eligible U.S. inventory and eligible foreign in-transit inventory and (ii) 85% of the net orderly liquidation value of eligible U.S. inventory and eligible foreign in-transit inventory (not to exceed $4,000,000), plus (c) the lesser of (i) 85% of the net orderly liquidation value of U.S. eligible machinery and equipment and (ii) $1,170,000 as of March 31, 2018 (subject to reduction as provided in the Credit Agreement), plus (d) 85% of eligible Canadian accounts receivable, plus (e) the lesser of (i) 70% of eligible Canadian inventory and (ii) 85% of the net orderly liquidation value of eligible Canadian inventory, less (f) swing loans outstanding under the U.S. and Canadian Credit Facility, less (g) letters of credit issued and undrawn under the U.S. and Canadian Credit Facility, less (h) a $5,000,000 minimum availability reserve, less (i) other reserves required by the Administrative Agent, and in each case subject to the definitions and limitations in the Credit Agreement. As of March 31, 2018, the company was in compliance with all covenant requirements and had borrowing capacity on the U.S. and Canadian Credit Facility under the Credit Agreement of $24,012,000, considering the minimum availability reserve, then-outstanding letters of credit, other reserves and the $11,250,000 dominion trigger amount described below. Borrowings under the U.S. and Canadian Credit Facility are secured by substantially all of the company’s U.S. and Canadian assets, other than real estate.

Interest will accrue on outstanding indebtedness under the Credit Agreement at the LIBOR rate, plus a margin ranging from 2.25% to 2.75%, or at the alternate base rate, plus a margin ranging from 1.25% to 1.75%, as selected by the company. Borrowings under the U.S. and Canadian Credit Facility are subject to commitment fees of 0.25% or 0.375% per year, depending on utilization.

The Credit Agreement contains customary representations, warranties and covenants. Exceptions to the operating covenants in the Credit Agreement provide the company with flexibility to, among other things, enter into or undertake certain sale and leaseback transactions, dispositions of assets, additional credit facilities, sales of receivables, additional indebtedness and intercompany indebtedness, all subject to limitations set forth in the Credit Agreement, as amended. The Credit Agreement also contains a covenant requiring the company to maintain minimum availability under the U.S. and Canadian Credit Facility of not less than the greater of (i) 11.25% of the maximum amount that may be drawn under the U.S. and Canadian Credit Facility for five (5) consecutive business days, or (ii) $5,000,000 on any business day. The company also is subject to dominion triggers under the U.S. and Canadian Credit Facility requiring the company to maintain borrowing capacity of not less than $11,250,000 on any business day or $12,500,000 for five consecutive days in order to avoid triggering full control by an agent for the lenders of the company's cash receipts for application to the company’s obligations under the agreement.

The Credit Agreement contains customary default provisions, with certain grace periods and exceptions, which provide that events of default that include, among other things, failure to pay amounts due, breach of covenants, representations or warranties, bankruptcy, the occurrence of a material adverse effect, exclusion from any medical reimbursement program, and an interruption of any material manufacturing facilities for more than 10 consecutive days. There were no borrowings outstanding under the U.S. and Canadian Credit Facility at March 31, 2018.

European Credit Facility

The Credit Agreement also provides for a revolving credit, letter of credit and swing line loan facility which gives the company and the European Borrowers the ability to borrow up to an aggregate principal amount of $30,000,000, with a $5,000,000 sublimit for letters of credit and a $2,000,000 sublimit for swing line loans (the “European Credit Facility”). Up to $15,000,000 of the European Credit Facility will be available to each of Invacare Limited (the “UK Borrower”) and Invacare Poirier SAS (the “French Borrower” and, together with the UK Borrower, the “European Borrowers”). The European Credit Facility matures in January 2021, together with the U.S. and Canadian Credit Facility.

The aggregate borrowing availability for each European Borrower under the European Credit Facility is determined based on a borrowing base formula. The aggregate borrowings of each of the European Borrowers under the European Credit Facility may not exceed an amount equal to (a) 85% of the European Borrower’s eligible accounts receivable, less (b) the European Borrower’s borrowings and swing line loans outstanding under the European Credit Facility, less (c) the European Borrower’s letters of credit issued and undrawn under the European Credit Facility, less (d) a $3,000,000 minimum availability reserve, less (e) other reserves required by the European Agent, and in each case subject to the definitions and limitations in the Credit Agreement. As of March 31, 2018, the aggregate borrowing availability to the European Borrowers under the European Credit Facility was approximately $11,397,000, considering the $3,000,000 minimum availability reserve and the $3,375,000 dominion trigger amount described below.

Interest will accrue on outstanding indebtedness under the European Credit Facility at the LIBOR rate, plus a margin ranging from 2.50% to 3.00%, or for swing line loans, at the overnight LIBOR rate, plus a margin ranging from 2.50% to 3.00%, as selected by the company. The margin that will be adjusted quarterly based on utilization. Borrowings under the European Credit Facility are subject to commitment fees of 0.25% or 0.375% per year, depending on utilization.

The European Credit Facility is secured by substantially all the personal property assets of the UK Borrower and its in-country subsidiaries, and all the receivables of the French Borrower and its in-country subsidiaries. The UK and French facilities (which comprise the European Credit Facility) are cross collateralized, and the US personal property assets previously pledged under the U.S. and Canadian Credit Facility also serve as collateral for the European Credit Facility.

The European Credit Facility is subject to customary representations, warranties and covenants generally consistent with those applicable to the U.S. and Canadian Credit Facility. Exceptions to the operating covenants in the Credit Agreement provide the company with flexibility to, among other things, enter into or undertake certain sale/leaseback transactions, dispositions of assets, additional credit facilities, sales of receivables, additional indebtedness and intercompany indebtedness, all subject to limitations set forth in the Credit Agreement.

The European Borrowers also are subject to cash dominion triggers under the European Credit Facility requiring the European Borrower to maintain borrowing capacity of not less than $3,375,000 on any business day or 12.50% of the maximum amount that may be drawn under the European Credit Facility for five (5) consecutive business days in order to avoid triggering full control by an agent for the Lenders of the European Borrower’s cash receipts for application to its obligations under the European Credit Facility.

The European Credit Facility is subject to customary default provisions, with certain grace periods and exceptions, consistent with those applicable to the U.S. and Canadian Credit Facility, which provide that events of default include, among other things, failure to pay amounts due, breach of covenants, representations or warranties, cross-default, bankruptcy, the occurrence of a material adverse effect, exclusion from any medical reimbursement program, and an interruption in the operations of any material manufacturing facility for more than 10 consecutive days.

Convertible senior subordinated debentures due 2027

In 2007, the company issued $135,000,000 principal amount of 4.125% Convertible Senior Subordinated Debentures due 2027 (the "debentures"), of which $0 principal amount remains outstanding as of March 31, 2018. The holders of the debentures exercised their right to require the company to repurchase all the debentures on February 1, 2017 at a price equal to 100% of the principal amount, which totaled $13,350,000. As a result of the repurchase, the company wrote-off unamortized debt fees of $207,000 and recognized amortization expense of $311,000 in the first quarter of 2017.

Convertible senior notes due 2021

In the first quarter of 2016, the company issued $150,000,000 aggregate principal amount of 5.00% Convertible Senior Notes due 2021 (the “2021 notes”) in a private offering to qualified institutional buyers pursuant to Rule 144A under the Securities Act. The 2021 notes bear interest at a rate of 5.00% per year payable semi-annually in arrears on February 15 and August 15 of each year, beginning August 15, 2016. The 2021 notes will mature on February 15, 2021, unless repurchased or converted in accordance with their terms prior to such date. Prior to August 15, 2020, the 2021 notes will be convertible only upon satisfaction of certain conditions and during certain periods, and thereafter, at any time until the close of business on the second scheduled trading day immediately preceding the maturity date. Unless and until the company obtains shareholder approval under applicable New York Stock Exchange rules, the 2021 notes will be convertible, subject to certain conditions, into only cash. If the company obtains such shareholder approval, the 2021 notes may be settled in cash, the company’s common shares or a combination of cash and the company’s common shares, at the company’s election.

Holders of the 2021 notes will have the right to require the company to repurchase all or some of their 2021 notes at 100% of their principal, plus any accrued and unpaid interest, upon the occurrence of certain fundamental changes. The initial conversion rate is 60.0492 common shares per $1,000 principal amount of 2021 notes (equivalent to an initial conversion price of approximately $16.65 per common share). The company evaluated the terms of the conversion features under the applicable accounting literature, including Derivatives and Hedging, ASC 815, and determined that the features did require separate accounting as a derivative. This derivative was capitalized on the balance sheet as a long-term liability and will be adjusted to reflect fair value each quarter. The fair value of the convertible debt conversion liability at issuance was $34,480,000. The fair value of the convertible debt conversion liability at March 31, 2018 was $55,527,000 compared to $53,154,000 as of December 31, 2017. The company recognized a loss of $2,373,000 for the three months ended March 31, 2018 compared to a gain of $6,731,000 for the three months ended March 31, 2017 related to the convertible debt conversion liability.

In connection with the offering of the 2021 notes, the company entered into privately negotiated convertible note hedge transactions with two financial institutions (the “option counterparties”). These transactions cover, subject to customary anti-dilution adjustments, the number of the company’s common shares that will initially underlie the 2021 notes, and are expected generally to reduce the potential equity dilution, and/or offset any cash payments in excess of the principal amount due, as the case may be, upon conversion of the 2021 notes. The company evaluated the note hedges under the applicable accounting literature, including Derivatives and Hedging, ASC 815, and determined that the note hedges should be accounted for as derivatives. These derivatives were capitalized on the balance sheet as long-term assets and will be adjusted to reflect fair value each quarter. The fair value of the convertible note hedge assets at issuance was $27,975,000. The fair value of the convertible note hedge assets at March 31, 2018 was $48,962,000 compared to $46,915,000 as of December 31, 2017. The company recognized a gain of $2,047,000 for the three months ended March 31, 2018 compared to a loss of $5,830,000 for the three months ended March 31, 2017 related to the convertible note hedge asset.

The company entered into separate, privately negotiated warrant transactions with the option counterparties at a higher strike price relating to the same number of the company’s common shares, subject to customary anti-dilution adjustments, pursuant to which the company sold warrants to the option counterparties. The warrants could have a dilutive effect on the company’s outstanding common shares and the company’s earnings per share to the extent that the price of the company’s common shares exceeds the strike price of those warrants. The initial strike price of the warrants is $22.4175 per share and is subject to certain adjustments under the terms of the warrant transactions. The company evaluated the warrants under the applicable accounting literature, including Derivatives and Hedging, ASC 815, and determined that the warrants meet the definition of a derivative, are indexed to the company's own stock and should be classified in shareholder's equity. The amount paid for the warrants and capitalized in shareholder's equity was $12,376,000.

The net proceeds from the offering of the 2021 notes were approximately $144,034,000, after deducting fees and offering expenses of $5,966,000, which were paid in 2016. These debt issuance costs were capitalized and are being amortized as interest expense through February 2021. In accordance with ASU 2015-03, Simplifying the Presentation of Debt Issuance Costs, these debt issuance costs are presented on the balance sheet as a direct deduction from the carrying amount of the related debt liability. Approximately $5,000,000 of the net proceeds from the offering were used to repurchase the company’s common shares from purchasers of 2021 notes in the offering in privately negotiated transactions. A portion of the net proceeds from the offering were used to pay the cost of the convertible note hedge transactions (after such cost is partially offset by the proceeds to the company from the warrant transactions), which net cost was $15,600,000.

The liability components of the 2021 notes consist of the following (in thousands):



	March 31, 2018			December 31, 2017
Principal amount of liability component	$	150,000		$150,000
