The decrease in statutory policyholders' surplus for the years ended December 31, 2023 and December 31, 2022 is primarily due to dividend payments to MGIC Investment Corporation ("the holding company") (discussed below), offset by statutory net income. For the years ended December 31, 2023, 2022, and 2021 there were no contributions made to MGIC or distributions from other insurance subsidiaries to us. Dividends paid by MGIC are shown in table 14.2 below.

- Definition Tabular disclosure of how the entity's reporting under GAAP as of the balance sheet date differs from the results based on prescribed and permitted accounting practices of the state or country of domicile in which a relevant statutory filing is made, or differences in results based on the National Association of Insurance Commissioners (NAIC) prescribed practices, or a combination thereof. Describes the accounting practices used and the related monetary effect on statutory surplus, net income, and risk-based capital. If an insurance enterprise's risk-based capital would have triggered a regulatory event had it not used a permitted practice, that fact is disclosed in the financial statements. Permitted statutory accounting practices include practices not prescribed but allowed by the domiciliary state insurance department regulatory authority. + References Reference 1: http://www.xbrl.org/2009/role/commonPracticeRef -Topic 944 -SubTopic 210 -Name Accounting Standards Codification -Section S99 -Paragraph 1 -Subparagraph (SX 210.7-03(a)(23)(c)) -Publisher FASB -URI https://asc.fasb.org//1943274/2147479440/944-210-S99-1 Reference 2: http://fasb.org/us-gaap/role/ref/legacyRef -Name Accounting Standards Codification -Topic 944 -SubTopic 505 -Section 50 -Paragraph 1 -Publisher FASB -URI https://asc.fasb.org//1943274/2147479989/944-505-50-1 Reference 3: http://fasb.org/us-gaap/role/ref/legacyRef -Name Accounting Standards Codification -Topic 944 -SubTopic 505 -Section 50 -Paragraph 6 -Publisher FASB -URI https://asc.fasb.org//1943274/2147479989/944-505-50-6 Reference 4: http://fasb.org/us-gaap/role/ref/legacyRef -Name Accounting Standards Codification -Topic 944 -SubTopic 505 -Section 55 -Paragraph 2 -Publisher FASB -URI https://asc.fasb.org//1943274/2147479956/944-505-55-2 Reference 5: http://fasb.org/us-gaap/role/ref/legacyRef -Name Accounting Standards Codification -Topic 944 -SubTopic 505 -Section 55 -Paragraph 1 -Publisher FASB -URI https://asc.fasb.org//1943274/2147479956/944-505-55-1 Reference 6: http://fasb.org/us-gaap/role/ref/legacyRef -Name Accounting Standards Codification -Topic 944 -SubTopic 505 -Section 50 -Paragraph 3 -Publisher FASB -URI https://asc.fasb.org//1943274/2147479989/944-505-50-3 + Details
