[1] As of March 31, 2017, the current portion of the Company's debt (i.e. becoming due in the next 12 months) included $14.3 million of the balance of its U.S. dollar denominated debt under the Credit Agreement facility, $6.7 million of the balance of its Japanese yen-denominated debt under the Credit Agreement facility and $6.0 million of the Japan subsidiary loan. The Company has classified the $72.5 million borrowed under the revolving line of credit as short term because it is the Company's intention to use the line of credit to borrow and pay back funds over short periods of time.
[2] The carrying value of the debt reflects the amounts stated in the above table less a debt discount of $11.9 million and debt issuance costs of $5.2 million (consisting of $14.2 million related to the Convertible Note and $2.9 million related to the credit agreement), which is not reflected in this table.
