TORONTO — AIG United Guaranty,1 whose affiliate companies provide mortgage guaranty insurance designed to increase home ownership, has announced that Mario Vachon will serve as Chief Risk Officer for AIG United Guaranty Canada.

The new office will offer Canadian consumers additional choice by providing innovative mortgage default insurance products for consumers, mortgage brokers, financial institutions, and secondary capital markets. According to Andy Charles, who will serve as president and CEO of Canadian operations, “Mario is a key hire for our organization and is valuable member of our leadership team. He brings a tremendous amount of knowledge and experience, as well as the drive required to build a successful mortgage insurance company.”

With more than 15 years of mortgage industry experience, Vachon has held senior-level positions with RBC Royal Bank and Canada Mortgage and Housing Corporation in the areas of Product Management, Risk, Treasury, and Securitization.

The mortgage insurance subsidiaries of AIG United Guaranty provide mortgage guaranty insurance service to financial institutions worldwide, helping to minimize reliance on government fiscal support through private-sector risk management. Mortgage insurance coverage on low-down-payment loans protects a lender against losses due to homeowner default. Home ownership studies show that loans with limited down payments have an increased likelihood of default, particularly in periods of severe or prolonged economic distress.
