Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The Company has prepared the accompanying unaudited Condensed Consolidated Financial Statements (“Financial Statements”) in accordance with the rules and regulations of the United States Securities and Exchange Commission (“SEC”) for interim financial information. Accordingly, the Financial Statements do not include all of the information and footnotes required by United States Generally Accepted Accounting Principles (“GAAP”) for annual financial statements. Therefore, the Financial Statements should be read in conjunction with the audited Consolidated Financial Statements contained in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2016, filed with the SEC on February 24, 2017. The condensed consolidated balance sheet at December 31, 2016, was derived from audited financial statements, but does not include all disclosures required by GAAP. In the opinion of management, all adjustments (consisting of normal recurring adjustments) necessary for a fair presentation have been included in the Financial Statements. The results for interim periods do not necessarily indicate the results that may be expected for any other interim period or for the full year. To conform to the current period presentation, certain amounts in the prior periods’ consolidated financial statements and notes have been reclassified. Such reclassifications were of an immaterial amount and had no effect on net income or stockholders’ equity. The Financial Statements include the accounts of UVE and its wholly-owned subsidiaries. All material intercompany balances and transactions have been eliminated in consolidation. Management must make estimates and assumptions that affect amounts reported in the Company’s Financial Statements and in disclosures of contingent assets and liabilities. Actual results could differ from those estimates.
Recently Adopted Accounting Pronouncements	Recently Adopted Accounting Pronouncements In March 2016, the Financial Accounting Standards Board (“FASB”) issued guidance which simplifies several aspects of the accounting for share-based payment transactions. The new guidance requires excess income tax benefits (windfalls) and deficiencies (shortfalls) to be recognized in the income statement as income tax benefits or charges when the awards vest or are settled. The former guidance required the recognition of excess tax benefits or deficiencies in stockholders’ equity. In addition, all income tax-related cash flows resulting from share-based payments will be reported as operating activities in the statement of cash flows under the new guidance. The guidance also allows us to repurchase more of an employee's shares for tax withholding purposes without triggering liability accounting; clarifies that all cash payments for tax withholdings made on an employee’s behalf should be presented as a financing activity on the Company’s statement of cash flows; and provides an accounting policy election to account for forfeitures as they occur. The guidance is effective for fiscal years and interim periods beginning after December 15, 2016, with early adoption permitted. The Company adopted this guidance effective January 1, 2017. The adoption of the new standard resulted in the recognition of excess tax benefit of $0.8 million reflected in the Company’s Condensed Consolidated Statements of Income as an income tax benefit for the six months ended June 30, 2017. Additionally, excess tax benefits on the Company’s Condensed Consolidated Statement of Cash Flows are presented as an operating activity on a prospective basis. The presentation requirement for cash flows related to employee taxes paid for withheld shares did not impact any of the periods presented in the Company’s Condensed Consolidated Statement of Cash Flows since these cash flows have historically been presented as a financing activity. The Company will continue to account for forfeitures as they occur. The standard also modifies the calculation of dilutive earnings per share to no longer use proceeds from tax benefits or deficiencies.
