5. Commitments and contingencies Operating and Capital Leases As of March 31, 2013, we had an aggregate of $15.4 million of financial commitments related to office space under noncancelable operating leases and equipment under capital leases. The aggregate of $15.4 million of future minimum commitments consisted of $3.9 million due for the remainder of fiscal 2013; $4.4 million due in fiscal 2014; $3.8 million due in fiscal 2015; and $3.3 million due in fiscal 2016. Legal Contingencies We were named in a lawsuit filed on September 9, 2010 in the Superior Court of the State of California, San Mateo County (Edwards v. Silver Spring Networks). The lawsuit claims to be a  class action  on behalf of California consumers, and alleges that smart meters are defective and generate incorrect bills. We have filed a motion to dismiss this case and, on September 1, 2011, the San Mateo Superior Court granted our motion without leave to amend as to two of the plaintiffs  causes of action and with leave to amend as to a third claim. On February 25, 2012 the plaintiffs filed an amended complaint. On May 30, 2012, we filed an answer to the amended complaint denying the plaintiffs  allegations. On August 3, 2012, the plaintiffs filed a second amended complaint, and on September 18, 2012, we filed a demurrer to one of the two claims asserted in the second amended complaint. The court has overruled our demurrer. On November 9, 2012, the plaintiffs filed a motion for class certification. A hearing on the class certification motion was held on January 25, 2013. On April 11, 2013, the court denied the class certification motion without prejudice. We intend to continue vigorously defending against the action. The amount of any potential exposure to us is not estimable at this time. On June 17, 2011, EON Corp. IP Holdings, LLC, a non-producing entity, filed suit in United States District Court for the Eastern District of Texas, Tyler Division against a number of smart grid providers, including Landis+Gyr, which was since acquired by Toshi
