In July 2019, the Company resolved the complaint filed by a qui tam relator in October 2017 in the United States District Court for the District of South Carolina. The complaint was the basis of the Office of Inspector General (OIG) subpoena dated February 2018 regarding Medicare billing practices relating to the Company’s hereditary cancer testing from 2014 to 2018. After a 17-month investigation, the Department of Justice declined to intervene in the case. The Company believes this demonstrated that the key allegations made in the complaint were false. In order to avoid a lengthy and distracting litigation with the qui tam relator, the Company entered into a settlement agreement on July 18, 2019 under which the Company would pay $9.1 to the qui tam relator in order to settle the matter. The Company paid the settlement amount of $9.1 in October 2019. The Company denies any wrongdoing and does not anticipate any material change in its billing practices.

In addition, the Company is subject to various claims and legal proceedings covering matters that arise in the ordinary course of its business activities. As of September 30, 2019, the management of the Company believes any reasonably possible liability that may result from the resolution of these matters will not have a material adverse effect on the Company’s consolidated financial position, operating results, or cash flows.

The Company leases certain office spaces and research and development laboratory facilities, vehicles, and office equipment with remaining lease terms ranging from one to six years. These leases require monthly lease payments that may be subject to annual increases throughout the lease term. Certain of these leases also include renewal options which allows the Company to, at its election, renew or extend the lease for a fixed or indefinite period of time. These optional periods have not been considered in the determination of the right-of-use-assets or lease liabilities associated with these leases as the Company did not consider it reasonably certain it would exercise the options.

The Company performed evaluations of its contracts and determined each of its identified leases are operating leases. For the three months ended September 30, 2019, the Company incurred $4.6 in lease costs which are included in operating expenses in the consolidated statement of operations in relation to these operating leases. Of such lease costs, $0.6 was variable lease expense and $0.1 was short-term lease expense, and neither of them were included in the measurement of the Company's operating ROU assets and lease liabilities. The variable rent expense is comprised primarily of the Company's proportionate share of operating expenses, property taxes, and insurance and is classified as lease expense due to the Company's election to not separate lease and non-lease components.

As of September 30, 2019, the maturities of the Company’s operating lease liabilities were as follows:

Fiscal year ending:
2020	$	11.9
2021		14.9
2022		13.7
2023		12.6
2024		12.3
Thereafter		19.3
Total lease payments	$	84.7

As of September 30, 2019, the weighted average remaining lease term is 6.0 years and the weighted average discount rate used to determine the operating lease liability was 3.87%.
