10. Commitments and Contingencies General Under finance products available in the point-of-sale and direct-to-consumer channels, consumers have the ability to borrow up to the maximum credit limit assigned to each individuals account. Unfunded commitments under these products aggregated $717.0 million at March 31, 2019. We have never experienced a situation in which all borrowers have exercised their entire available lines of credit at any given point in time, nor do we anticipate this will ever occur in the future. Moreover, there would be a concurrent increase in assets should there be any exercise of these lines of credit. We also have the effective right to reduce or cancel these available lines of credit at any time. Additionally our CAR operations provide floor-plan financing for a pre-qualified network of independent automotive dealers and automotive finance companies in the buy-here, pay-here used car business. The financings allow dealers and finance companies to borrow up to the maximum pre-approved credit limit allowed in order to finance ongoing inventory needs. These loans are secured by the underlying auto inventory and, in certain cases where we have other lending products outstanding with the dealer, are secured by the collateral under those lending arrangements as well, including any outstanding dealer reserves. As of March 31, 2019, CAR had unfunded outstanding floor-plan financing commitments totaling $8.0 million. Each draw against unused commitments is reviewed for conformity to pre-established guidelines. Under agreements with third -party originating and other financial institutions, we have pledged security (collateral) related to their issuance of consumer credit and purchases thereunder, of which $11.4 million remains pledged as of March 31, 2019 to support various ongoing contractual obligations. Under agreements with third -party originating and other financial institutions, we have agreed to indemnify the financial institutions for certain liabilities associated with the services we provide on behalf of the financial institutionssuch indemnification obligations generally being limited to instances in which we either (a) have been afforded the opportunity to defend against any potentially indemnifiable claims or (b) have reached agreement with the financial institutions regarding settlement of potentially indemnifiable claims. As of March 31, 2019, we have assessed the likelihood of any potential payments related to the aforementioned contingencies as remote. We will accrue liabilities related to these contingencies in any future period if and in which we assess the likelihood of an estimable payment as probable. We also are subject to certain minimum payments under cancelable and non-cancelable lease arrangements. For further information regarding these commitments, see Note 7, Leases. Litigation We are involved in various legal proceedings that are incidental to the conduct of our business, none of which are expected to be material to us.
