Regulatory Information | Regulatory Information Statutory Requirements Our insurance subsidiaries, NMIC and Re One, file financial statements in conformity with statutory accounting principles (SAP) prescribed or permitted by the Wisconsin OCI, NMIC's principal regulator. Prescribed SAP includes state laws, regulations and general administrative rules, as well as a variety of publications of the National Association of Insurance Commissioners (NAIC). The Wisconsin OCI recognizes only statutory accounting practices prescribed or permitted by the state of Wisconsin for determining and reporting the financial condition and results of operations of an insurance company and for determining its solvency under Wisconsin insurance laws. NMIC and Re One generated combined statutory net income of $30.7 million and $98.0 million for the three and nine months ended September 30, 2025, respectively, compared to $20.0 million and $90.7 million for the three and nine months ended September 30, 2024, respectively. The Wisconsin OCI has imposed a prescribed accounting practice for the treatment of statutory contingency reserves that differs from the treatment promulgated by the NAIC. Under Wisconsin OCI's prescribed practice mortgage guaranty insurers are required to reflect changes in their contingency reserves through statutory income. Such approach contrasts with the NAIC's treatment, which records changes to contingency reserves directly to unassigned funds. As a Wisconsin-domiciled insurer, NMIC's statutory net income reflects an expense associated with the change in its contingency reserve. While such treatment impacts NMIC's statutory net income, it does not have an effect on NMIC's statutory capital position. The following table presents NMIC's statutory surplus, contingency reserve, statutory capital and risk-to-capital (RTC) ratio as of September 30, 2025 and December 31, 2024.
| September 30, 2025 |  | December 31, 2024 |  |  |  |
| (In Thousands)
Statutory surplus | $ | 982,245 |  |  | $ | 984,362 |  |  |  |  |
Contingency reserve | 2,161,465 |  |  | 1,905,990 |  |  |  |  |
Statutory capital (1) | $ | 3,143,710 |  |  | $ | 2,890,352 |  |  |  |  |
Risk-to-capital | 13.1:1 |  | 12.7:1 |  |  |  |
(1) Represents the total of the statutory surplus and contingency reserve. Re One had $2.1 million of statutory capital at September 30, 2025 and December 31, 2024. NMIH is not subject to any limitations on its ability to pay dividends except those generally applicable to corporations that are incorporated in Delaware. Delaware law provides that dividends are only payable out of a corporation's capital surplus or, subject to certain limitations, recent net profits. NMIC and Re One are subject to certain rules and regulations prescribed by jurisdictions in which they are authorized to operate and the GSEs that may restrict their ability to pay dividends to NMIH. NMIC has the capacity to pay $98.4 million of aggregate ordinary dividends to NMIH during the twelve-month period ending December 31, 2025, and, on June 2, 2025, NMIC paid a $98.4 million ordinary course dividend to NMIH.
