SCHEDULE V
LITIGATION

I. Ordinary Course of Business Litigation

As a residential mortgage lender originating, closing and servicing loans in all 50 states, Quicken Loans Inc. (and its Subsidiaries) may, at any point in time, be named as a party to dozens of legal proceedings which arise in the ordinary course of business, such as actions alleging improper lending practices, improper servicing, quiet title actions, improper foreclosure practices, violations of consumer protection laws, etc. and on account of consumer bankruptcies. In many of these actions, Quicken Loans (and its Subsidiaries) may not be the real party of interest (because Quicken Loans is not the servicer of the loan or the holder of the note) but it may appear in the pleadings because it is in the chain of title to property over which there may be a dispute. Such matters are turned over to the servicer of the loan for those loans Quicken Loans or its Subsidiary do not service. In other cases, such as lien avoidance cases brought in bankruptcy, Quicken Loans or its Subsidiary are insured by title insurance and the case is turned over to the title insurer who tenders our defense.

As to other matters that arise in the ordinary course, management does not believe that the amount of liability, if any, for any of the pending matters individually or in the aggregate will materially affect Quicken Loans’ consolidated financial position in a material way. However, regardless of the outcome of this or other matters referred to herein, litigation can have a significant effect on Quicken Loans and its Subsidiaries for other reasons such as defense costs, diversion of management focus and resources, and other factors. To the best of Quicken Loans’ information and belief, there are no outstanding judgments, liens or orders that have not been satisfied.

III. Regulatory and Administrative Matters

As a non-depository mortgage banker, Quicken Loans (and its Subsidiaries) are regulated by and subject to various state agencies that oversee and regulate (a) mortgage lending and the activities of bank and/or non-bank financial institutions and/or (b) insurance agency / escrow agent activities and practices. These state agencies are generally authorized to: issue licenses or registrations where state law requires; conduct periodic on-site or remote audits or examinations of the regulated institution’s books, files and practices; investigate consumer complaints; issue findings of audit or compliance variances that may require refunds to borrowers for charges beyond those permitted under the state’s laws or regulations; assess fines or penalties if administrative rules are not adhered to, and/or require other corrective actions to be taken. These agencies also have the authority to seek revocation of an institution’s or individual’s license or registration to operate as a mortgage lender or loan originator in the state. In the ordinary course of business and in any given year, Quicken Loans (and its Subsidiaries) participate in and respond to
