Some three weeks after Fitch and S&P assigned 'AA/Stable' and 'AA-/Stable' insurer financial strength ratings respectively to Westpac Lenders Mortgage Insurance Ltd, Moody's followed with the assignment of a 'Aa3/Negative rating. The rating considers the amount of support, including capital and other forms, available to WLMI from its parent, Westpac Banking Corp, as well as the strong stand-alone credit profile of WLMI itself. The negative outlook is in line with that on the bank. WLMI has operated as the bank's captive LMI since it was established in 1996, and now operates as a sister company to St George Insurance Australia Pty Ltd., but under the same management and division.
