A first tranche of $25.0 million principal amount was funded upon execution of the Hercules Loan Agreement in October 2017 and the remaining $15.0 million principal amount was funded in March 2018. The Term Loans bear interest at a variable per annum rate at the greater of (i) the prime rate plus 4.00% and (ii) 8.25% . The interest rate on the Term Loans was 9.00% at June 30, 2018 . Pursuant to the terms of the Hercules Loan Agreement, the Term Loan Maturity Date has been extended from May 1, 2021 to November 1, 2021 as a result of the achievement of a financing milestone during the second quarter of fiscal year 2018. The Company is obligated to make monthly payments of accrued interest until June 1, 2019 , or the Interest-only Period, subject to certain terms and conditions, followed by monthly installments of principal and interest through the maturity date. The Interest-only Period has been extended to December 1, 2019 as a result of the achievement of a financing milestone during the second quarter of fiscal year 2018. The Interest-only Period may be further extended until June 1, 2020 if a certain clinical milestone is met, as specified in the Hercules Loan Agreement. Prepayment of the Term Loan is subject to a prepayment charge. The Company is also obligated to pay an end of term charge of 6.55% of the principal amount of the Term Loans funded under the Hercules Loan Agreement, on the earlier of the maturity date or the date that the Term Loans otherwise become due and payable. The Company’s obligations under the Hercules Loan Agreement are secured by a first lien security interest in substantially all of the Company’s and its subsidiaries’ respective assets, other than intellectual property. The Hercules Loan Agreement includes customary affirmative and restrictive covenants and representations and warranties, including a minimum cash covenant that ceases to apply if the Company achieves certain clinical development and financing milestones as set forth in the Hercules Loan Agreement. The Hercules Loan Agreement also includes customary events of default. Upon the occurrence of an event of default, a default interest rate of an additional 5.00% may be applied to the outstanding principal balance, and Hercules may declare all outstanding obligations immediately due and payable and take such other actions as set forth in the Hercules Loan Agreement. Concurrent with each funding of the Term Loans, the Company is required to issue to Hercules a warrant, or the Warrants, to purchase a number of its common shares equal to 3.00% of the principal amount of the relevant Term Loan funded divided by the exercise price, which is based on the lowest three-day volume-weighted average price for the three consecutive trading days prior to the funding date for such Term Loan. The Warrants may be exercised on a cashless basis, and are immediately exercisable through the seventh anniversary of the applicable funding date. In connection with the first tranche funded under the Hercules Loan Agreement, the Company issued a Warrant to Hercules exercisable for an aggregate of 49,800 of its common shares at an exercise price of $15.06 per common share. Concurrent with the funding of the second tranche, the Company issued a Warrant to Hercules exercisable for an aggregate of 23,910 of its common shares at an exercise price of $18.82 per common share. The Company accounted for the Warrants as equity instruments since they were indexed to the Company’s common shares and met the criteria for classification in shareholders’ equity (deficit). The relative fair value of the Warrants related to the first and second tranche funding were approximately $0.5 million and $0.3 million , respectively, and were treated as a discount to the Term Loans. This amount is being amortized to interest expense using the effective interest method over the life of the Term Loans. The Company estimated the fair value of the Warrants using the Black-Scholes model based on the following key assumptions: Tranche 1 Tranche 2 Exercise price $15.06 $18.82 Common share price on date of issuance $14.39 $18.96 Volatility 73.2% 72.3% Risk-free interest rate 2.15% 2.78% Expected dividend yield —% —% Contractual term (in years) 7.00 years 7.00 years The Company issued the first tranche of the Term Loans at a discount of $2.1 million , including the relative fair value of the related Warrant, and incurred financing costs of $1.3 million relating to the Hercules Loan Agreement which are recorded as an offset to long-term debt on the Company’s unaudited condensed consolidated balance sheets. The second tranche of the Term Loans was issued at a discount of $1.3 million , including the relative fair value of the related Warrant. The debt discount and deferred financing costs are being amortized over the term of the debt using the effective interest method, and are included in interest expense in the Company’s unaudited condensed consolidated statements of operations. During the three months ended June 30, 2018 , interest expense included $0.4 million of amortized debt discount and issuance costs related to the Term Loans.
