14. Other Current Liabilities

The Company is a party to a Development and License Agreement with Carrier Corporation (“Carrier”) regarding the payment of royalties on the sale of each of the Company’s 200 kilowatt (“C200”) microturbines. During the three months ended September 30, 2013, we reached our repayment threshold level and the fixed rate royalty was reduced by 50%. Carrier earned $0.9 million in royalties for C200 and C1000 Series system sales during each of the fiscal years ended March 31, 2018 and 2017, which will continue until the obsolescence of the C200 microturbine product line. Earned royalties of $0.2 million and $0.3 million were unpaid as of March 31, 2018 and March 31, 2017, respectively, and are included in accrued expenses in the accompanying balance sheets.
