26  Summary of Risk Factors   We may not continue to meet the GSEs’ mortgage insurer eligibility requirements and our returns may decrease as we are required to maintain more capital in order to maintain our eligibility. The amount of insurance we write could be adversely affected if lenders and investors select alternatives to private mortgage insurance. Competition or changes in our relationships with our customers could reduce our revenues, reduce our premium yields and/or increase our losses. Changes in the business practices of the GSEs, federal legislation that changes their charters or a restructuring of the GSEs could reduce our revenues or increase our losses. The benefit of our net operating loss carryforwards may become substantially limited. We are involved in legal proceedings and are subject to the risk of additional legal proceedings in the future. Resolution of our dispute with the Internal Revenue Service could adversely affect us. Because we establish loss reserves only upon a loan default rather than based on estimates of our ultimate losses on risk in force, losses may have a disproportionate adverse effect on our earnings in certain periods. Because loss reserve estimates are subject to uncertainties, paid claims may be substantially different than our loss reserves. We rely on our management team and our business could be harmed if we are unable to retain qualified personnel or successfully develop and/or recruit their replacements. Loan modification and other similar programs may not continue to provide benefits to us and our losses on loans that re-default can be higher than what we would have paid had the loan not been modified. If the volume of low down payment home mortgage originations declines, the amount of insurance that we write could decline, which would reduce our revenues. State capital requirements may prevent us from continuing to write new insurance on an uninterrupted basis. Downturns in the domestic economy or declines in the value of borrowers’ homes from their value at the time their loans closed may result in more homeowners defaulting and our losses increasing. The mix of business we write affects the likelihood of losses occurring, our Minimum Required Assets for purposes of the GSE Financial Requirements, and our premium yields. The premiums we charge may not be adequate to compensate us for our liabilities for losses and as a result any inadequacy could materially affect our financial condition and results of operations. We are susceptible to disruptions in the servicing of mortgage loans that we insure. Changes in interest rates, house prices or mortgage insurance cancellation requirements may change the length of time that our policies remain in force. Your ownership in our company may be diluted by additional capital that we raise or if the holders of our outstanding convertible debt convert that debt into shares of our common stock. Our debt obligations materially exceed our holding company cash and investments. We could be adversely affected if personal information on consumers that we maintain is improperly disclosed and our information technology systems may become outdated and we may not be able to make timely modifications to support our products and services. Our Australian operations may suffer significant losses.
