Loan Funding and Purchase Commitments For loans listed on the platform as a result of direct marketing efforts, we have committed to invest in such loans if investors do not provide funding for all or a portion of such loans.

In connection with transitional activities related to the acquisition of Springstone, in June 2014, we entered into a contingent loan purchase agreement with an issuing bank that originates loans facilitated by Springstone and a third-party investor that has agreed to purchase certain of these loans from the issuing bank.

The contingent loan purchase commitment provides that we will purchase such loans from the bank if the third-party investor defaults on its loan purchase obligations to the bank through January 2016.

Credit Support Agreement We are subject to a credit support agreement with a certificate investor. The credit support agreement requires us to pledge and restrict cash in support of its contingent obligation to reimburse the investor for credit losses on loans underlying the investor’s certificate that are in excess of a specified, aggregate loss threshold. We are contingently obligated to pledge cash, not to exceed $5.0 million, to support this contingent obligation. As of March 31, 2015, approximately $3.4 million was pledged and restricted to support this contingent obligation. As of March 31, 2015, the credit losses pertaining to the investor’s certificates have not exceeded the specified threshold, nor are future credit losses expected to exceed the specified threshold, and thus no liability has been recorded. We currently do not anticipate recording losses under this credit support agreement. If losses related to the credit support agreement are later determined to be likely to occur and are estimable, results of operations could be affected in the period in which such losses are recorded. Loan Purchase Obligation Under our loan account program with WebBank, our primary issuing bank, WebBank retains ownership of the loans facilitated through our marketplace for two business days after origination. As part of this arrangement, we have committed to purchase the loans at par plus accrued interest, at the conclusion of the two business days. As of March 31, 2015 we were committed to purchase loans with an outstanding principal balance of $3.6 million at par plus accrued interest.

The purpose of the investigation is to determine whether Springstone engaged in unlawful acts or practices in connection with the marketing, issuance, and servicing of loans for healthcare related financing during the period.
