Nature of Operations and Basis of Presentation	1. Nature of Operations and Basis of Presentation
	Nature of Operations
	Universal Insurance Holdings, Inc., (“UIH”) is a Delaware corporation originally incorporated as Universal Heights, Inc., in November 1990. UIH with its wholly-owned subsidiaries (the “Company”), is a vertically integrated insurance holding company performing all aspects of insurance underwriting, distribution and claims. Through its wholly-owned subsidiaries, including Universal Property & Casualty Insurance Company (“UPCIC”) and American Platinum Property and Casualty Insurance Company (“APPCIC”), collectively referred to as the “Insurance Entities”, the Company is principally engaged in the property and casualty insurance business offered primarily through a network of independent agents. Risk from catastrophic losses is managed through the use of reinsurance agreements. The Company’s primary product is homeowners insurance offered in nine states as of March 31, 2015, including Florida, which comprises the vast majority of the Company’s in-force policies. See “—Note 5 (Insurance Operations)” for more information regarding the Company’s insurance operations.
	The Company generates revenues primarily from the collection of premiums and invests funds in excess of those retained for claims-paying obligations and insurance operations. Other significant sources of revenue include commissions collected from reinsurers, policy fees collected from policyholders through our wholly-owned managing general agency subsidiary and payment plan fees charged to policyholders who choose to pay their premiums in installments.
	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, they do not include all of the information and footnotes required by United States Generally Accepted Accounting Principles (“GAAP”) for complete 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, 2014, filed with the SEC on February 25, 2015. The condensed consolidated balance sheet at December 31, 2014, 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 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 UIH 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.

Significant Accounting Policies	2. Significant Accounting Policies
	The Company reported Significant Accounting Policies in its Annual Report on Form 10-K for the year ended December 31, 2014.  Below are revised disclosures required to be reported on a quarterly basis.
	Goodwill.  Goodwill arising from the acquisition of a business is initially measured at cost and not subject to amortization.  We assess goodwill for potential impairments at the end of each fiscal year, or during the year if an event or other circumstance indicates that we may not be able to recover the carrying amount of the asset.  Goodwill is included under Other Assets in the Condensed Consolidated Balance Sheets.
	Recently Issued Accounting Pronouncements
	In July 2013, the Financial Accounting Standards Board (“FASB”) issued accounting guidance on the presentation of an unrecognized tax benefit when a net operating loss carryforward, a similar tax loss or a tax credit carryforward exists. Under this guidance, an unrecognized tax benefit, or a portion of an unrecognized tax benefit, should generally be presented in the financial statements as a reduction to a deferred tax asset for a net operating loss carryforward. This guidance is effective for fiscal years and interim periods beginning after December 15, 2013, but earlier adoption is permitted. The Company adopted this guidance effective January 1, 2014. The adoption did not have an impact on the presentation of the Company’s financial statements and notes herein.

At March 31, 2015, we held fixed maturity and equity securities that were in an unrealized loss position as presented in the table above. For fixed maturity securities with significant declines in value, we perform quarterly fundamental credit analysis on a security-by-security basis, which includes consideration of credit quality and credit ratings, review of relevant industry analyst reports and other available market data. For fixed maturity and equity securities, the Company considers whether it has the intent and ability to hold the securities for a period of time sufficient to recover its cost basis. Where the Company lacks the intent and ability to hold to recovery, or believes the recovery period is extended, the security’s decline in fair value is considered other than temporary and is recorded in earnings. Based upon management’s intent and ability to hold the securities until recovery and its credit analysis of the individual issuers of the securities, management has no reason to believe the unrealized losses for securities available for sale at March 31, 2015 are other than temporary.

Reinsurance

Insurance [Abstract]
Reinsurance	4. Reinsurance
	The Company seeks to reduce its risk of loss by reinsuring certain levels of risk in various areas of exposure with other insurance enterprises or reinsurers, generally as of the beginning of the hurricane season on June 1 of each year. The Company’s reinsurance program consists of excess of loss, quota share and catastrophe reinsurance, subject to the terms and conditions of the applicable agreements. The Company is responsible for insured losses related to catastrophes and other events in excess of coverage provided by its reinsurance program. The Company remains responsible for the settlement of insured losses irrespective of the failure of any of its reinsurers to make payments otherwise due to the Company.
	The Company reduced the percentage of premiums ceded by UPCIC to its quota share reinsurers to 30% beginning with the reinsurance program effective June 1, 2014, from 45% under the prior year quota share contracts that were effective June 1, 2013 through May 31, 2014. By ceding 15 percentage points less premium to its quota share reinsurers, the Company expects to increase its profitability by retaining more premium. The reduction in cession rate also decreases the amount of losses and loss adjustment expenses (“LAE”) that may be ceded by UPCIC and effectively increases the amount of risk retained by UPCIC and the Company. The reduction of cession rate also reduces the amount of ceding commissions earned from the Company’s quota share reinsurer during the contract term and decreases the amount of deferred ceding commission, which is a component of net deferred policy acquisition costs.
	Amounts recoverable from reinsurers are estimated in a manner consistent with the reinsurance contracts. Reinsurance premiums, losses and LAE are accounted for on a basis consistent with those used in accounting for the original policies issued and the terms of the reinsurance contracts. Deferred ceding commissions are netted against policy acquisition costs and amortized over the effective period of the related insurance policies.
	In order to reduce credit risk for amounts due from reinsurers, the Insurance Entities seek to do business with financially sound reinsurance companies and regularly evaluate the financial strength of all reinsurers used.

	Regulatory Requirements and Restrictions
	The Insurance Entities are subject to regulations and standards of the Florida Office of Insurance Regulation (“OIR”).  UPCIC also is subject to regulation and standards of regulatory authorities in other states where it is licensed, although as a Florida-domiciled insurer its principal regulatory authority is the OIR.  These standards require the Insurance Entities to maintain specified levels of statutory capital and restrict the timing and amount of dividends and other distributions that may be paid by the Insurance Entities to the parent company. Except in the case of extraordinary dividends, these standards generally permit dividends to be paid from statutory unassigned surplus of the regulated subsidiary and are limited based on the regulated subsidiary’s level of statutory net income and statutory capital and surplus. The maximum dividend that may be paid by UPCIC and APPCIC to their immediate parent company, Universal Insurance Holding Company of Florida (“UIHCF”), without prior regulatory approval is limited by the provisions of Florida Statutes. These dividends are referred to as “ordinary dividends.” However, if the dividend, together with other dividends paid within the preceding twelve months, exceeds this statutory limit or is paid from sources other than earned surplus, the entire dividend is generally considered an “extraordinary dividend” and must receive prior regulatory approval.
	In accordance with Florida Statutes, and based on the calculations performed by the Company as of December 31, 2014, UPCIC has the capacity to pay ordinary dividends of $27.7 million during 2015. APPCIC does not have the capacity to pay ordinary dividends during 2015. For the three months ended March 31, 2015, no dividends were paid from UPCIC or APPCIC to UIHCF. Dividends paid to the shareholders of UIH during the three months ended March 31, 2015 were paid from the earnings of UIH and its non-insurance subsidiaries.
	The Florida Insurance Code requires insurance companies to maintain capitalization equivalent to the greater of ten percent of the insurer’s total liabilities or $5.0 million. The following table presents the amount of capital and surplus calculated in accordance with statutory accounting principles, which differ from GAAP, and an amount representing ten percent of total liabilities for both UPCIC and APPCIC as of the dates presented (in thousands):
		March 31,			December 31,

	Ten percent of total liabilities
	UPCIC	$	47,443		$	42,659

	Statutory capital and surplus
	UPCIC	$	215,270		$	200,173
	APPCIC	$	14,003		$	14,036
	As of the dates in the table above, both UPCIC and APPCIC met the Florida capitalization requirement. As of March 31, 2015 UPCIC also met the capitalization requirements of the other states in which it is licensed.  UPCIC and APPCIC are also required to adhere to prescribed premium-to-capital surplus ratios and have met those requirements at such dates.
	The Insurance Entities are required by various state laws and regulations to maintain certain assets in depository accounts. The following table represents assets held by insurance regulators as of the dates presented (in thousands):

	Dividends
	On January 13, 2015, UIH declared a cash dividend of $0.12 per share on its outstanding common stock paid on March 2, 2015, to the shareholders of record at the close of business on February 18, 2015.
	Contingently Redeemable Common Stock
	On December 2, 2014, UIH sold 1,000,000 registered shares of its common stock at a price of $19.00 per share, in a privately negotiated transaction, to Ananke Catastrophe Investments Ltd. (“Ananke”), an affiliate of Nephila Capital Ltd., which is subject to certain holding period restrictions.  Ananke is required to hold the shares of common stock for a minimum of six months and then may: 1) sell up to one-third during the next three-month period, 2) sell another one-third during the next three-month period and 3) sell the remaining shares purchased thereafter.
	The shares sold to Ananke had been subject to a redemption option, conditioned on a covered loss index swap being triggered for payment.
	On February 19, 2015, the company entered into an amended agreement with Ananke to delete, in its entirety effective December 2, 2014, the provision giving rise to the redemption.  This modification results in classification of the common shares in permanent equity on the date of the amendment.  No consideration was exchanged with the amendment since both parties agreed that, given the remote possibility of the redemption to occur, the value of the redemption feature was de-minimis.  The effects of the amendment were recorded during the quarter ended March 31, 2015.  The following table has been provided to illustrate pro-forma effect of the amendment had it been in place as of December 31, 2014.

	During the three months ended March 31, 2015 and 2014, the Company recorded approximately $15.7 million and $9.6 million of income taxes, respectively.  Our effective tax rate for the quarter ending March 31, 2015 is 41.3% compared to a 41.4% effective tax rate for the same period in the prior year.  In arriving at these rates, the Company considers a variety of factors including the forecasted full year pre-tax results, the U.S. federal tax rate of 35%, expected non-deductible expenses, and estimated state income taxes.  The Company’s final effective tax rate for the full year is dependent on the level of pre-tax income and the magnitude of any non-deductible expenses in relation to that pre-tax income.
	Tax years that remain open for purposes of examination of the Company’s income tax liability due to taxing authorities, include the years ended December 31, 2013, 2012 and 2011. However, there is currently an IRS examination underway related to the loss carryback of realized losses from securities sold during 2012 applied to the 2009 tax year.

Fair Value Disclosures [Abstract]
Fair Value Measurements	13. Fair Value Measurements
	GAAP defines fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants as of the measurement date. GAAP describes three approaches to measuring the fair value of assets and liabilities: the market approach, the income approach and the cost approach. Each approach includes multiple valuation techniques. GAAP does not prescribe which valuation technique should be used when measuring fair value, but does establish a fair value hierarchy that prioritizes the inputs used in applying the various techniques. Inputs broadly refer to the assumptions that market participants use to make pricing decisions, including assumptions about risk. Level 1 inputs are given the highest priority in the hierarchy while Level 3 inputs are given the lowest priority. Assets and liabilities carried at fair value are classified in one of the following three categories based on the nature of the inputs to the valuation technique used:
	•	Level 1 — Observable inputs that reflect unadjusted quoted prices for identical assets or liabilities in active markets as of the reporting date. Active markets are those in which transactions for the asset or liability occur in sufficient frequency and volume to provide pricing information on an ongoing basis.
	•	Level 2 — Observable market-based inputs or unobservable inputs that are corroborated by market data.
	•	Level 3 — Unobservable inputs that are not corroborated by market data. These inputs reflect management’s best estimate of fair value using its own assumptions about the assumptions a market participant would use in pricing the asset or liability.
	Summary of significant valuation techniques for assets measured at fair value on a recurring basis
	Level 1
	Common stock: Comprise actively traded, exchange-listed U.S. and international equity securities. Valuation is based on unadjusted quoted prices for identical assets in active markets that the Company can access.
	Mutual funds: Comprise actively traded funds. Valuation is based on daily quoted net asset values for identical assets in active markets that the Company can access.
	Level 2
	U.S. government obligations and agencies: Comprise U.S. Treasury Bills or Notes or U.S. Treasury Inflation Protected Securities. The primary inputs to the valuation include quoted prices for identical assets in inactive markets or similar assets in active or inactive markets, contractual cash flows, benchmark yields and credit spreads.
	Corporate Bonds: Comprise investment-grade fixed income securities. The primary inputs to the valuation include quoted prices for identical assets in inactive markets or similar assets in active or inactive markets, contractual cash flows, benchmark yields and credit spreads.
	Mortgage-backed and asset-backed securities: Comprise securities that are collateralized by mortgage obligations and other assets. The primary inputs to the valuation include quoted prices for identical assets in inactive markets or similar assets in active or inactive markets, contractual cash flows, benchmark yields, collateral performance and credit spreads.
	Redeemable Preferred Stock: Comprise preferred stock securities that are redeemable. The primary inputs to the valuation include quoted prices for identical or similar assets in markets that are not active.
	Short-term investments: Comprise investment securities subject to remeasurement with original maturities within one year but more than three months. The primary inputs to the valuation include quoted prices for identical or similar assets in markets that are not active.
	As required by GAAP, assets and liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value measurement. The Company’s assessment of the significance of a particular input to the fair value measurement requires judgment, and may affect the placement of the asset or liability within the fair value hierarchy levels.
	The following tables set forth by level within the fair value hierarchy the Company’s assets that were measured at fair value including those on a recurring basis as of the dates presented (in thousands):

	The Company utilizes third-party independent pricing services that provide a price quote for each fixed maturity and equity security. Management reviews the methodology used by the pricing services. If management believes that the price used by the pricing service does not reflect an orderly transaction between participants, management will use an alternative valuation methodology. There were no adjustments made by the Company to the prices obtained from the independent pricing source for any fixed maturities or equity securities included in the tables above.
	The following table summarizes the carrying value and estimated fair values of the Company’s financial instruments that are not carried at fair value as of the dates presented (in thousands):

	Promissory note	$	1,390	$	1,390	$	—	$	—
	Level 3
	Long-term debt: The fair value of the surplus note was determined by management from the expected cash flows discounted using the interest rate quoted by the holder. The State Board of Administration of Florida (“SBA”) is the holder of the surplus note and the quoted interest rate is below prevailing rates quoted by private lending institutions. However, as the Company’s use of funds from the surplus note is limited by the terms of the agreement, the Company has determined the interest rate quoted by the SBA to be appropriate for purposes of establishing the fair value of the note.
	The fair value of the term loan and promissory note approximates the carrying value given the original issue discount which was calculated based on the present value of future cash flows using the Company’s effective borrowing rate.

Risk from catastrophic losses is managed through the use of reinsurance agreements. The Company’s primary product is homeowners insurance offered in nine states as of March 31, 2015, including Florida, which comprises the vast majority of the Company’s in-force policies. See “—Note 5 (Insurance Operations)” for more information regarding the Company’s insurance operations.
	The Company generates revenues primarily from the collection of premiums and invests funds in excess of those retained for claims-paying obligations and insurance operations. Other significant sources of revenue include commissions collected from reinsurers, policy fees collected from policyholders through our wholly-owned managing general agency subsidiary and payment plan fees charged to policyholders who choose to pay their premiums in installments.
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, they do not include all of the information and footnotes required by United States Generally Accepted Accounting Principles (“GAAP”) for complete 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, 2014, filed with the SEC on February 25, 2015. The condensed consolidated balance sheet at December 31, 2014, 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 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 UIH 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.
Goodwill	Goodwill.  Goodwill arising from the acquisition of a business is initially measured at cost and not subject to amortization.  We assess goodwill for potential impairments at the end of each fiscal year, or during the year if an event or other circumstance indicates that we may not be able to recover the carrying amount of the asset.  Goodwill is included under Other Assets in the Condensed Consolidated Balance Sheets.
Recently Issued Accounting Pronouncements	Recently Issued Accounting Pronouncements
	In July 2013, the Financial Accounting Standards Board (“FASB”) issued accounting guidance on the presentation of an unrecognized tax benefit when a net operating loss carryforward, a similar tax loss or a tax credit carryforward exists. Under this guidance, an unrecognized tax benefit, or a portion of an unrecognized tax benefit, should generally be presented in the financial statements as a reduction to a deferred tax asset for a net operating loss carryforward. This guidance is effective for fiscal years and interim periods beginning after December 15, 2013, but earlier adoption is permitted. The Company adopted this guidance effective January 1, 2014. The adoption did not have an impact on the presentation of the Company’s financial statements and notes herein.
