Deferred Policy Acquisition Costs Deferred policy acquisition costs consist of commissions paid to outside agents, premium taxes, salaries, and certain other underwriting costs that are incremental or directly related to the successful acquisition of new and renewal insurance contracts and are amortized over the life of the related policy in proportion to premiums earned. Deferred policy acquisition costs are limited to the amount that will remain after deducting from unearned premiums and anticipated investment income, the estimated losses and loss adjustment expenses, and the servicing costs that will be incurred as premiums are earned. The Company’s deferred policy acquisition costs are further limited by excluding those costs not directly related to the successful acquisition of insurance contracts. Deferred policy acquisition cost amortization was $133.8 million and $129.8 million for the three months ended March 31, 2015 and 2014, respectively. The Company does not defer advertising expenditures but expenses them as incurred. The Company recorded net advertising expenses of approximately 16.0 million and $6.4 million for the three months ended March 31, 2015 and 2014, respectively.

The financial data of the Company included herein are unaudited. In the opinion of management, all material adjustments of a normal recurring nature have been made to present fairly the Company’s financial position at March 31, 2015 and the results of operations, comprehensive income, and cash flows for the periods presented. These statements were prepared in accordance with the instructions for interim reporting and do not contain certain information that was included in the annual financial statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2014. Readers are urged to review the Company’s Annual Report on Form 10-K for the year ended December 31, 2014 for more complete descriptions and discussions. Operating results and cash flows for the three months ended March 31, 2015 are not necessarily indicative of the results that may be expected for the year ending December 31, 2015.

Use of Estimates

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosures of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. These estimates require the Company to apply complex assumptions and judgments, and often the Company must make estimates about effects of matters that are inherently uncertain and will likely change in subsequent periods. The most significant assumptions in the preparation of these condensed consolidated financial statements relate to reserves for losses and loss adjustment expenses. Actual results could differ from those estimates (See Note 1 “Summary of Significant Accounting Policies” of the Notes to Consolidated Financial Statements in the Company’s Annual Report on Form 10-K for the year ended December 31, 2014).

Earnings per Share

Potentially dilutive securities representing approximately 2,000 and 48,000 shares of common stock for the three months ended March 31, 2015 and 2014, respectively, were excluded from the computation of diluted earnings per common share for these periods because their effect would have been anti-dilutive.

Deferred Policy Acquisition Costs

Deferred policy acquisition costs consist of commissions paid to outside agents, premium taxes, salaries, and certain other underwriting costs that are incremental or directly related to the successful acquisition of new and renewal insurance contracts and are amortized over the life of the related policy in proportion to premiums earned. Deferred policy acquisition costs are limited to the amount that will remain after deducting from unearned premiums and anticipated investment income, the estimated losses and loss adjustment expenses, and the servicing costs that will be incurred as premiums are earned. The Company’s deferred policy acquisition costs are further limited by excluding those costs not directly related to the successful acquisition of insurance contracts. Deferred policy acquisition cost amortization was $133.8 million and $129.8 million for the three months ended March 31, 2015 and 2014, respectively. The Company does not defer advertising expenditures but expenses them as incurred. The Company recorded net advertising expenses of approximately 16.0 million and $6.4 million for the three months ended March 31, 2015 and 2014, respectively.
