9. Commitments and Contingencies Leases and Other Long-Term Commitments In May 2018, the Company entered into a lease agreement to lease facilities under a noncancelable operating lease that expires January 2026. Estimated annual future minimum payments related to the Companys operating leases were as follows at September 30, 2018 (in thousands): 2018 $ 748 2019 1,880 2020 1,192 2021 886 2022 898 Thereafter 2,848 $ 8,452 Royalty Payments Pursuant to the terms of its 2006 license agreement with the Ipsen Group, the Company is required to make royalty payments of two percent of net sales of NUPLAZID. Corporate Credit Card Program In connection with the Companys credit card program, the Company established a letter of credit for $2.0 million, which has automatic annual extensions and is fully secured by restricted cash. Fleet Program In connection with the Companys fleet program, the Company established letters of credit with the leasing entities totaling $0.7 million, which have automatic annual extensions and are fully secured by restricted cash. Legal Proceedings Between July 19 and August 3, 2018, following recent negative publicity about NUPLAZID, three purported Company stockholders filed putative securities class action complaints (captioned Staublein v. ACADIA Pharmaceuticals, Inc., Case No. 18-cv-01647-JAH-MDD, Stone v. ACADIA Pharmaceuticals Inc., Case No. 18-cv-01672-LAB-JMA, and Barglow v. ACADIA Pharmaceuticals Inc., Case No. 18-cv-1812-DMS-WVG) in the U.S. District Court for the Southern District of California against the Company and certain of its current executive officers. The complaints generally allege that defendants violated Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 by making materially false and misleading statements regarding the Companys business, operations, and prospects by failing to disclose that adverse events and safety concerns regarding NUPLAZID threatened initial and continuing FDA approval, and by failing to disclose that the Company engaged in business practices likely to attract regulatory scrutiny. The complaints seek unspecified monetary damages and other relief. Several putative lead plaintiffs have filed motions to consolidate the cases and to appoint a lead plaintiff. The motions have been fully briefed and are set to be heard on January 3, 2019. The defendants response to the complaints is stayed pending resolution of the lead plaintiff motions. The Company has assessed such legal proceedings, and given the unpredictability inherent in litigation, the Company cannot predict the outcome of these matters. At this time, the Company is unable to estimate possible losses or ranges of losses that may result from such legal proceedings, and it has not accrued any amounts in connection with such legal proceedings other than ongoing attorneys fees . Government Investigation In September 2018 the Company received a civil investigative demand (CID) from the Department of Justice (DOJ) requesting certain documents and information related to the Companys sales and marketing of NUPLAZID. The Company is cooperating with the DOJs request. Responding to the CID will require considerable resources and no assurance can be given as to the timing or outcome of the DOJs investigation.
