14.  Other Current Liabilities

In September 2007, the Company entered into a Development and License Agreement (the “Development Agreement”) with UTC Power Corporation (“UTCP”), a division of United Technologies Corporation. The Development Agreement engaged UTCP to fund and support the Company’s continued development and commercialization of the Company’s 200 kilowatt (“C200”) microturbine. Pursuant to the terms of the Development Agreement, UTCP contributed $12.0 million in cash and approximately $0.8 million of in-kind services toward the Company’s efforts to develop the C200. In return, the Company pays UTCP an ongoing royalty of 10% of the sales price of the C200 sold to customers other than UTCP until the aggregate of UTCP’s cash and in-kind services investment has been recovered and, thereafter, the royalty will be reduced to 5% of the sales price. In August 2009, the Development Agreement was assigned by UTCP to Carrier Corporation (“Carrier”).

On January 14, 2011, the Company entered into an amendment to the Development Agreement with Carrier that amended the royalty payment from a certain percentage of the sales prices to a predetermined fixed rate for each microturbine system covered by the amendment. The fixed rate royalty was reduced by 50% during the three months ended September 30, 2013 as a result of the contractual reduction. Carrier earned approximately $0.3 million and $0.8 million in royalties for C200 and C1000 Series system sales during the first quarter of Fiscal 2015 and Fiscal 2014, respectively. Earned royalties of approximately $0.3 million and $0.6 million were unpaid as of June 30, 2014 and March 31, 2014, respectively, and are included in accrued expenses in the accompanying balance sheets.
