Additionally, U.S. Government contract costs are subject to periodic audit and adjustment. Based on information currently available, and based on its evaluation of such information, the Company believes the legal proceedings in which it is currently involved are not material or are not likely to result in a material adverse effect on the Company’s business, financial condition or results of operations, or cannot currently be estimated. The Company is a party to a proceeding filed by Kandice Neals on behalf of herself and others similarly situated (the "Neals Plaintiff") against the Company on March 21, 2019 in the Circuit Court of Cook County, Illinois County Department, Chancery Division. The complaint asserted that the Company violated the Illinois Biometric Information Privacy Act in the alleged collection, use, and storage of her and others' biometric data derived from fingerprint scans taken for authentication purposes on point-of-sale systems. The Neals lawsuit was removed to the Federal District Court for the Northern District of Illinois (the District Court") and was subsequently dismissed on December 19, 2019 without prejudice. On January 15, 2020, the Neals Plaintiff filed an amended complaint against ParTech, Inc. with the District Court. On January 29, 2020, ParTech, Inc. filed its answer and affirmative defenses to the amended complaint. The Company believes the Neals lawsuit is without merit. The Company does not currently believe an accrual is appropriate, but will continue to monitor the lawsuit to provide for probable and estimable losses. In 2016, the Company's Audit Committee commenced an internal investigation into conduct at the Company's China and Singapore offices and voluntarily notified the SEC and the U.S. Department of Justice ("DOJ") of the internal investigation. Following the conclusion of the Audit Committee's internal investigation, the Company voluntarily reported the relevant findings of the investigation to the China and Singapore authorities. During the full year ended December 31, 2019, the Company recorded $0.6 million of expenses relating to the internal investigation, including expenses of outside legal counsel and forensic accountants, compared to $1.1 million for the full year ended December 31, 2018. In early April 2019, the SEC notified the Company that based on current information, it did not intend to recommend an enforcement action against the Company; shortly thereafter, the DOJ advised that it did not intend to separately proceed; the Company is cooperating with the China and Singapore authorities. The Company is currently not able to predict what actions these authorities might take, or what the likely outcome of any such actions might be, or estimate the range of reasonably possible fines or penalties, which may be material. The China and Singapore authorities have a broad range of civil and criminal sanctions, and the imposition of fines or penalties could have a material adverse effect on the Company’s business, prospects, reputation, financial condition, results of operations or cash flows.
