Basis of presentation

The accompanying consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America ("GAAP"), as codified in the Accounting Standards Codification ("ASC"). Our consolidated financial statements include the accounts of MGIC Investment Corporation and its majority-owned subsidiaries. Intercompany transactions and balances have been eliminated. In accordance with GAAP, we are required to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting periods. Actual results could differ from those estimates. We have considered subsequent events through the date of this filing.

Reclassifications

Certain reclassifications to 2016 and 2015 amounts have been made in the accompanying consolidated financial statements to conform to the 2017 presentation. See Note 3 - "Significant Accounting Policies" for a discussion of our adoption of accounting guidance in 2017 that resulted in other reclassifications.
