12. COMMITMENTS AND CONTINGENCIES

Bank Line of Credit — In April 2017 the Company renewed its revolving credit facility which extended the maturity date to June 30, 2019. In May 2018, the facility was revised and the commitment amount increased to $65,000.

Borrowings on the facility bear interest at the greater of a fixed rate of 3.50% per annum or at the borrower’s option of (i) LIBOR plus 1% or (ii) Prime minus 1.50%. As of September 30, 2018 and December 31, 2017, the Company had no borrowings under the credit facility.

As of September 30, 2018, the Company’s available credit under this facility was $60,272 as a result of the issuance of an aggregate amount of $4,728 of various standby letters of credit, which were required in connection with certain office lease and other agreements. The Company incurs a 1% per annum fee on the outstanding balance of issued letters of credit.

Leases —The Company maintains operating leases with expiration dates that extend through 2029. The Company incurred expense relating to its operating leases of $3,963 and $3,866 for the three months ended September 30, 2018 and 2017, respectively, and expenses of $11,864 and $11,302 for the nine months ended September 30, 2018 and 2017, respectively. In addition, during the second quarter of 2016, the Company decided to sublet a portion of its growth space in the U.K. which required a sublease loss reserve to be recognized for the estimated net economics of such sublet. The expense related to the aforementioned sublease loss reserve, which is remeasured at each reporting period for the three months ended September 30, 2018 and 2017, was $0 and $19, respectively, and $0 and $169 for the nine months ended September 30, 2018 and 2017, respectively.

Contractual Arrangements —In the normal course of business, the Company enters into contracts that contain a variety of representations and warranties and which provide indemnification for specified losses, including certain indemnification of certain officers, directors and employees.

Legal —In the ordinary course of business, from time to time the Company and its affiliates are involved in judicial or regulatory proceedings, arbitration or mediation concerning matters arising in connection with the conduct of its businesses, including contractual and employment matters. In addition, government agencies and self-regulatory organizations conduct periodic examinations and initiate administrative proceedings regarding the Company’s business, including, among other matters, compliance, accounting and operational matters, that can result in censure, fine, the issuance of cease-and-desist orders or the suspension or expulsion of a broker-dealer, investment advisor, or its directors, officers or employees. In view of the inherent difficulty of determining whether any loss in connection with such matters is probable and whether the amount of such loss can be reasonably estimated, particularly in cases where claimants seek substantial or indeterminate damages or where investigations and proceedings are in the early stages, the Company cannot estimate the amount of such loss or range of loss, if any, related to such matters, how or if such matters will be resolved, when they will ultimately be resolved, or what the eventual settlement, fine, penalty or other relief, if any, might be. Subject to the foregoing, the Company believes, based on current knowledge and after consultation with counsel, that it is not currently party to any material pending proceedings, individually or in the aggregate, the resolution of which would have a material effect on the Company.
