Convertible Senior Notes

On September 25, 2017 and October 11, 2017, the Company issued $40.0 million and $6.0 million, respectively, of 5.50% Convertible Senior Notes due 2022 (the “Notes”). The Company received net proceeds, after deducting the initial purchaser’s discount and offering expenses payable by the Company, of approximately $43.0 million. The Notes bear interest at a rate of 5.50% per year, payable semi-annually in arrears on March 15 and September 15 of each year, with payments commencing on March 15, 2018. The Notes mature on September 15, 2022, unless earlier purchased by the Company, redeemed, or converted.

The Notes are unsecured obligations of Maxwell and rank senior in right of payment to any of Maxwell’s subordinated indebtedness; equal in right of payment to all of Maxwell’s unsecured indebtedness that is not subordinated; effectively subordinated in right of payment to any of Maxwell’s secured indebtedness to the extent of the value of the assets securing such indebtedness; and structurally subordinated to all indebtedness and other liabilities (including trade payables) of Maxwell’s subsidiaries.

The Notes are convertible into cash, shares of the Company’s common stock, or a combination thereof, at the Company’s election, upon the satisfaction of specified conditions and during certain periods as described below. The initial conversion rate is 157.5101 shares of the Company’s common stock per $1,000 principal amount of Notes, representing an initial effective conversion price of $6.35 per share of common stock and premiums of 27% and 29% to the Company’s $5.00 and $4.94 stock prices at the September 25, 2017 and October 11, 2017 dates of issuance, respectively. The conversion rate may be subject to adjustment upon the occurrence of certain specified events as provided in the indenture governing the Notes, dated September 25, 2017 between the Company and Wilmington Trust, National Association, as trustee (the “Indenture”), but will not be adjusted for accrued but unpaid interest. As of March 31, 2018, the if-converted value of the Notes did not exceed the principal value of the Notes.

Prior to the close of business on the business day immediately preceding June 15, 2022, the Notes will be convertible at the option of holders only upon the satisfaction of specified conditions and during certain periods. Thereafter until the close of business on the business day immediately preceding maturity, the Notes will be convertible at the option of the holders at any time regardless of these conditions.

Upon the occurrence of certain fundamental changes involving the Company, holders of the Notes may require the Company to repurchase for cash all or part of their Notes at a repurchase price equal to 100% of the principal amount of the Notes to be repurchased, plus accrued and unpaid interest, if any, to, but excluding, the fundamental change repurchase date.

The Company may not redeem the Notes prior to September 20, 2020. The Company may redeem the Notes, at its option, in whole or in part on or after September 20, 2020 if the last reported sale price of the Company’s common stock has been at least 130% of the conversion price then in effect for at least 20 trading days

The Company considered the features embedded in the Notes, that is, the conversion feature, the Company's call feature, and the make-whole feature, and concluded that they are not required to be bifurcated and accounted for separately from the host debt instrument.

The Notes included an initial purchaser’s discount of $2.5 million, or 5.5%. This discount is recorded as an offset to the debt and is amortized over the expected life of the Notes using the effective interest method.

Upon conversion by the holders, the Company may elect to settle such conversion in shares of its common stock, cash, or a combination thereof. As a result of its cash conversion option, the Company segregated the liability component of the instrument from the equity component. The liability component was measured by estimating the fair value of a non-convertible debt instrument that is similar in its terms to the Notes. The calculation of the fair value of the debt component required the use of Level 3 inputs, including utilization of credit assumptions and high yield bond indices. Fair value was estimated using an income approach, through discounting future interest and principal payments due under the Notes at a discount rate of 12.0%, an interest rate equal to the estimated borrowing rate for similar non-convertible debt. The excess of the initial proceeds from the Notes over the estimated fair value of the liability component was $8.5 million and was recognized as a debt discount and recorded as an increase to additional paid-in capital, and will be amortized over the expected life of the Notes using the effective interest method. Amortization of the debt discount is recognized as non-cash interest expense.

The transaction costs of $0.5 million incurred in connection with the issuance of the Notes were allocated to the liability and equity components based on their relative values. Transaction costs allocated to the liability component are being amortized using the effective interest method and recognized as non-cash interest expense over the expected term of the Notes. Transaction costs allocated to the equity component of $0.1 million reduced the value of the equity component recognized in stockholders’ equity.

The initial purchaser debt discount, the equity component debt discount and the transaction costs allocated to the liability are being amortized over the contractual term to maturity of the Notes using an effective interest rate of 12.2%.

Revolving Line of Credit

The Company has a Loan and Security Agreement (the “Loan Agreement”) with East West Bank (“EWB”) whereby EWB made available to the Company a secured credit facility in the form of a revolving line of credit (the “Revolving Line of Credit”). On May 8, 2018, the Company entered into an amendment to the Loan Agreement to amend, restate and extend the Revolving Line of Credit for a three-year period expiring on May 8, 2021. The Revolving Line of Credit is available up to a maximum of the lesser of: (a) $25.0 million; or (b) a certain percentage of domestic and foreign trade receivables, plus, for the twelve months ending May 8, 2019, the lesser of: (a) $5.0 million; and (b) a certain portion of the Company’s cash and cash equivalents.

As of March 31, 2018, the amount available under the Revolving Line of Credit, net of borrowings, was $8.9 million. In general, amounts borrowed under the Revolving Line of Credit are secured by a lien on all of the Company’s assets, including its intellectual property, as well as a pledge of 100% of its equity interests in the Company’s Swiss subsidiary and a pledge of 65% of its equity interests in the Company’s Korean subsidiary. The obligations under the Loan Agreement are also guaranteed directly by the Company’s Swiss and Korean subsidiaries. In the event that the Company is in violation of the representations, warranties and covenants made in the Loan Agreement, including certain financial covenants set forth therein, the Company may not be able to utilize the Revolving Line of Credit or repayment of amounts owed pursuant to the Loan Agreement could be accelerated. The Company is currently in compliance with the financial covenants that it is required to meet during the term of the credit agreement including the minimum two-quarter rolling EBITDA and minimum liquidity requirements.

Amounts borrowed under the Revolving Line of Credit bear interest, payable monthly. Such interest shall accrue based upon, at the Company’s election, subject to certain limitations, either a Prime Rate plus a margin ranging from 0% to 0.50% or the LIBOR Rate plus a margin ranging from 2.75% to 3.25%, the specific rate for each as determined based upon the Company’s leverage ratio from time to time.

The Company is required to pay an annual commitment fee equal to $125,000, and an unused commitment fee of the average daily unused amount of the Revolving Line of Credit, payable monthly, equal to a per annum rate in a range of 0.30% to 0.50%, as determined by the Company’s leverage ratio on the last day of the previous fiscal quarter. Borrowings under the Revolving Line of Credit were $5.0 million and $0 as of March 31, 2018 and December 31, 2017, respectively. The interest rate on the Revolving Line of Credit as of March 31, 2018 was 4.75%.

Other Long-term Borrowings

The Company has various financing agreements for vehicles. These agreements are for up to an original three-year repayment period with interest rates ranging from 0.9% to 1.9%. At March 31, 2018 and December 31, 2017, $109,000 and $115,000, respectively, was outstanding under these financing agreements.
