15.  Commitments and Contingencies

Purchase Commitments

As of September 30, 2016, the Company had firm commitments to purchase inventories of approximately $25.8 million through Fiscal 2019. Certain inventory delivery dates and related payments are not firmly scheduled; therefore, amounts under these firm purchase commitments will be payable upon the receipt of the related inventories.

Lease Commitments

The Company leases offices and manufacturing facilities under various non-cancelable operating leases expiring at various times through the fiscal year ending March 31, 2020. All of the leases require the Company to pay maintenance, insurance and property taxes. The lease agreements for primary office and manufacturing facilities provide for rent escalation over the lease term and renewal options for five-year periods. Rent expense is recognized on a straight-line basis over the term of the lease. The difference between rent expense recorded and the amount paid is credited or charged to deferred rent, which is included in other long-term liabilities in the accompanying balance sheets. The balance of deferred rent was approximately $0.2 million as of each of September 30, 2016 and March 31, 2016. Rent expense was approximately $0.6 million during each of the three months ended September 30, 2016 and 2015. Rent expense was approximately $1.2 million during each of the six months ended September 30, 2016 and 2015.

Other Commitments

In September 2010, the Company was awarded a grant from the U.S. Department of Energy (“DOE”) for the research, development and testing of a more efficient microturbine CHP system. The contract had a term of five years, a project cost of approximately $11.7 million and was completed in September 2015. The DOE contributed $5.0 million toward the project, of which $4.2 million was allocated to the Company, and the Company incurred approximately $6.7 million in research and development expense. The Company billed the DOE under the contract for this project a cumulative amount of $4.2 million through September 30, 2015, the date on which the contract was completed.

The Company has agreements with certain of its distributors requiring that if the Company renders parts obsolete in inventories the distributors own and hold in support of their obligations to serve fielded microturbines, then the Company is required to replace the affected stock at no cost to the distributors. While the Company has never incurred costs or obligations for these types of replacements, it is possible that future changes in the Company’s product technology could result and yield costs to the Company if significant amounts of inventory are held at distributors. As of September 30, 2016, no significant inventories were held at distributors.

Legal Matters

Federal Securities Class Action

Two putative securities class action complaints were filed against the Company and certain of its current and former officers in the United States District Court for the Central District of California under the following captions:  David Kinney, etc. v. Capstone Turbine, et al., No. 2:15-CV-08914 on November 16, 2015 (the “Kinney Complaint”) and Kevin M. Grooms, etc. v. Capstone Turbine, et al., No. 2:15-CV-09155 on December 18, 2015 (the “Grooms Complaint”).

The putative class in the Kinney Complaint is comprised of all purchasers of the Company’s securities between November 7, 2013 and November 5, 2015.  The Kinney Complaint alleges material misrepresentations and omissions in public statements regarding BPC and the likelihood that BPC would not be able to fulfill many legal and financial obligations to the Company.  The Kinney Complaint also alleges that the Company’s financial statements were not appropriately adjusted in light of this situation and were not maintained in accordance with GAAP, and that the Company lacked adequate internal controls over accounting.  The Kinney Complaint alleges that these public statements and accounting irregularities constituted violations by all named defendants of Section 10(b) of the Exchange Act, and Rule 10b-5 thereunder, as well as violations of Section 20(a) of the Exchange Act by the individual defendants.  The Grooms Complaint makes allegations and claims that are substantially identical to those in the Kinney Complaint, and both complaints seek compensatory damages of an undisclosed amount.  On January 16, 2016, several shareholders filed motions to consolidate the Kinney and Grooms actions and for appointment as lead plaintiff.  On February 29, 2016, the Court granted the motions to consolidate, and appointed a lead plaintiff.  On May 6, 2016, a Consolidated Amended Complaint with allegations and claims substantially identical to those of the Kinney Complaint was filed in the consolidated action.  The putative class period in the Consolidated Amended Complaint is June 12, 2014 to November 5, 2015. Defendants filed a motion to dismiss the Consolidated Amended Complaint on June 17, 2016. Plaintiffs’ opposition was filed July 29, 2016, and Defendants’ reply was filed September 23, 2016. The Company has not recorded any liability as of September 30, 2016 since any potential loss is not probable or reasonably estimable given the preliminary nature of the proceedings.

State Derivative Lawsuits — California

On February 18, 2016, a purported shareholder derivative action was filed in Los Angeles Superior Court in the State of California against the Company and certain of its current and former officers and directors under the following caption:  Stesiak v. Jamison, et al., No. BC610782.  The lawsuit alleges that certain of the Company’s current and former officers and directors knew or should have known that BPC would be unable to fulfill its obligations to the Company, but allowed the Company to make false and misleading statements regarding BPC and the Company’s financial condition.  The complaint also alleges that the defendants failed to timely adjust the Company’s account receivables and backlog to reflect BPC’s inability to pay the Company.  The complaint asserts causes of action for breach of fiduciary duty and unjust enrichment.  It demands damages for the amount of damage sustained by the Company as a result of the individual defendants’ alleged breach of fiduciary duties and unjust enrichment, that the Company institute corporate governance reforms, and disgorgement from the individual defendants.  On May 5, 2016, the parties filed a stipulation and proposed order seeking to stay this action until such time as the defendants’ motion(s) to dismiss the federal securities class action are decided.  On May 10, 2016, the Court entered that proposed order. A status conference is scheduled for December 16, 2016.
