Arch Mortgage Insurance Company Announces Ability to Comply with PMIERs 2.0

GREENSBORO, N.C.–()–Arch Mortgage Insurance Company and United Guaranty Residential
Insurance Company (together “Arch MI”) today provided guidance on their
compliance under the revised Private Mortgage Insurer Eligibility
Requirements (PMIERs 2.0) published by Fannie Mae and Freddie Mac on
September 27, 2018.

As previously disclosed, as of June 30, 2018, Arch MI satisfied the
original PMIERs financial requirements with an estimated sufficiency
ratio of 134%. Under the revised requirements of PMIERs 2.0, as of June
30, 2018, Arch MI’s sufficiency ratio (calculated as Available Assets
divided by Required Assets as defined within PMIERs) would have been
approximately 126% and its estimated Available Assets would continue to
exceed the GSEs’ eligibility requirements. PMIERs 2.0 is not expected to
have a significant impact on Arch MI’s operations or have a material
impact on its capital position as of the anticipated effective date of
March 31, 2019.
