On December 13, 2012, the United States Bankruptcy Court for the District of Delaware issued an order approving the Stipulation of Settlement (the “Stipulation”) entered into by The PMI Group, Inc. (“TPG”), the Official Committee of Unsecured Creditors in TPG’s Chapter 11 bankruptcy case (the “Creditors’ Committee”), TPG’s subsidiary PMI Mortgage Insurance Co. (“MIC”), the receiver for MIC (the “Receiver”) and the special deputy receiver of MIC (the “Deputy Receiver” and, together with MIC, TPG, the Creditors’ Committee and the Receiver, the “Parties”) with respect to certain issues that were in dispute among the Parties. On December 14, 2012, the Superior Court of the State of Arizona in and for the County of Maricopa, which is overseeing MIC’s receivership proceedings, issued an order approving the Stipulation.

Certain terms of the Stipulation are described below:

1. With respect to the approximately $2.2 billion in net operating loss carryforwards at issue among the Parties, MIC will pay TPG $20 million for the exclusive use of $1 billion of such net operating loss carryforwards and TPG will have the exclusive use of the remaining approximately $1.2 billion of net operating loss carryforwards. MIC will also have the right to direct the use of any net operating losses of MIC and its subsidiaries with respect to any taxable period ending after January 1, 2012. MIC and TPG will remain consolidated in the tax group.

2. TPG is in the process of voluntarily terminating its pension plan. It is expected that the underfunding of this plan upon termination would require a payment to the plan of approximately $15 million to $20 million. TPG will pay certain administrative fees and costs associated with the standard termination and MIC will pay the funding shortfall.

3. TPG has three reinsurance subsidiaries to which MIC and certain of its subsidiaries have ceded risk. Pursuant to the Stipulation, the reinsurance subsidiaries are to enter into commutation agreements pursuant to which all such ceded risk is to be commuted and outstanding intercompany amounts are to be settled. The commutation agreements require that the reinsurance subsidiaries make payments which total an aggregate of approximately $47.4 million to MIC and certain of its subsidiaries.

4. Both TPG and MIC have asserted an entitlement to the distribution on an allowed claim in the liquidation of Reliance Insurance Company in an approximate amount of $1.88 million. Under the Stipulation, TPG waives and transfers, in favor of MIC, its asserted claim to the distribution.

5. In connection with the sale in 2008 by MIC of its Australian operations to QBE Holdings (AAP) Pty Limited (“QBE”), both TPG and MIC have asserted an entitlement to a potential claim against QBE and/or QBE Insurance Group Limited in the approximate amount of $2.5 million. Under the Stipulation, MIC waives and transfers, in favor of TPG, its asserted claim to any recovery from QBE and/or QBE Insurance Group Limited with respect to that matter.

6. Under the Stipulation, the Parties provide a mutual waiver and release of any and all other claims, including the claims that MIC has filed against the TPG estate with the Bankruptcy Court, with certain exceptions specified in the Stipulation.

Effectiveness of the Stipulation is contingent on the satisfaction of a number of conditions. There can be no assurance that such conditions will be satisfied in a timely manner or at all or that the Stipulation will become effective.

Please refer to the Stipulation, a copy of which (without exhibits) is attached hereto and incorporated herein, for further information regarding the terms and conditions thereof.
