Description of Business, Basis of Presentation, and Summary of Significant Accounting Policies	(1) Description of Business, Basis of Presentation, and Summary of Significant Accounting Policies Description of Business. Primerica, Inc. (the "Parent Company"), together with its subsidiaries (collectively, "we", "us" or the "Company"), is a leading distributor of financial products to middle-income households in the United States and Canada. We assist our clients in meeting their needs for term life insurance, which we underwrite, and mutual funds, annuities, managed investments and other financial products, which we distribute primarily on behalf of third parties. Our primary subsidiaries include the following entities: Primerica Financial Services, Inc. ("PFS"), a general agency and marketing company; Primerica Life Insurance Company ("Primerica Life"), our principal life insurance company; Primerica Financial Services (Canada) Ltd., a holding company for our Canadian operations, which includes Primerica Life Insurance Company of Canada ("Primerica Life Canada") and PFSL Investments Canada Ltd. ("PFSL Investments Canada"); and PFS Investments Inc. ("PFS Investments"), an investment products company and broker-dealer. Primerica Life, domiciled in Massachusetts, owns National Benefit Life Insurance Company ("NBLIC"), a New York insurance company. We established Peach Re, Inc. ("Peach Re") and Vidalia Re, Inc. (“Vidalia Re”) as special purpose financial captive insurance companies and wholly owned subsidiaries of Primerica Life. Peach Re and Vidalia Re have each entered into separate coinsurance agreements with Primerica Life whereby Primerica Life has ceded certain level-premium term life insurance policies to Peach Re and Vidalia Re (respectively, the “Peach Re Coinsurance Agreement” and the “Vidalia Re Coinsurance Agreement”). Basis of Presentation. We prepare our financial statements in accordance with U.S. generally accepted accounting principles ("U.S. GAAP"). These principles are established primarily by the Financial Accounting Standards Board ("FASB"). The preparation of financial statements in conformity with U.S. GAAP requires us to make estimates and assumptions that affect financial statement balances, revenues and expenses and cash flows, as well as the disclosure of contingent assets and liabilities. Management considers available facts and knowledge of existing circumstances when establishing the estimates included in our financial statements. The accompanying unaudited condensed consolidated financial statements contain all adjustments, generally consisting of normal recurring accruals, which are necessary to fairly present the balance sheets as of June 30, 2017 and December 31, 2016, the statements of income and comprehensive income (loss) for the three and six months ended June 30, 2017 and 2016, and the statements of stockholders' equity and cash flows for the six months ended June 30, 2017 and 2016. Results of operations for interim periods are not necessarily indicative of results for the entire year or of the results to be expected in future periods. These unaudited condensed consolidated financial statements have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission ("SEC"). Certain information and note disclosures normally included in annual financial statements prepared in accordance with U.S. GAAP have been condensed or omitted pursuant to those rules and regulations, although the Company believes that the disclosures made are sufficient to make the information not misleading. These unaudited condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto that are included in our Annual Report on Form 10-K for the year ended December 31, 2016 ("2016 Annual Report"). Use of Estimates. The most significant items that involve a greater degree of accounting estimates and actuarial determinations subject to change in the future are the valuation of investments, deferred policy acquisition costs ("DAC"), liabilities for future policy benefits and unpaid policy claims, and income taxes. Estimates for these and other items are subject to change and are reassessed by management in accordance with U.S. GAAP. Actual results could differ from those estimates. Consolidation. The accompanying unaudited condensed consolidated financial statements include the accounts of the Company and those entities required to be consolidated under applicable accounting standards. All material intercompany profits, transactions, and balances among the consolidated entities have been eliminated. Reclassifications. Certain reclassifications have been made to prior-period amounts to conform to current-period reporting classifications. These reclassifications had no impact on net income or total stockholders' equity. Significant Accounting Policies. All significant accounting policies remain unchanged from the 2016 Annual Report. New Accounting Principles. In March 2016, the FASB issued Accounting Standards Update No 2016-09 (“ASU 2016-09”) Compensation—Stock Compensation (Topic 718) - Improvements to Employee Share-Based Payment Accounting. ASU 2016-09 intends to simplify several aspects of the accounting for share-based payment transactions, including the recognition of income tax consequences of awards, the classification of awards as either equity or liabilities, the method of recognizing award forfeitures, and the presentation of items within the statement of cash flows. The most notable impact on the Company’s financial statements involved the change in accounting for the income tax consequences associated with share-based payment transactions in the income statement. Prior to the adoption of ASU 2016-09, the tax effect of the difference between the cumulative compensation cost of a share-based award recognized for financial reporting purposes and the deduction of the award for tax purposes (“excess tax benefits or deficiencies”) was recognized as an adjustment to additional paid-in capital in the statement of stockholders’ equity. The amendments in ASU 2016-09 require that the excess tax benefits or deficiencies be recognized as a reduction to or an increase of income tax expense in the income statement. We adopted the amendments in ASU 2016-09 pertaining to excess tax benefits or deficiencies during the first quarter of 2017 on a prospective basis, which resulted in a reduction of income tax expense of approximately $0.9 million and $4.2 million for the excess tax benefit of share-based transactions for the three and six months ended June 30, 2017, respectively. ASU 2016-09 also changes the presentation of excess tax benefits or deficiencies in the cash flow statement from a financing activity to an operating activity. Therefore, we have presented the excess tax benefits or deficiencies as cash flows from operating activities within the accompanying consolidated statements of cash flows for all periods presented. The adoption of all other amendments outlined in ASU 2016-09 had either no impact to our financial statements or an immaterial impact to our financial statements. Future Application of Accounting Standards. Recent accounting guidance not discussed above is not applicable, is immaterial to our financial statements, or did not or is not expected to have a material impact on our business. For additional information on new accounting pronouncements and recent accounting principles and their impact, if any, on our financial position or results of operations, see Note 1 (Description of Business, Basis of Presentation, and Summary of Accounting Policies) to our consolidated financial statements within our 2016 Annual Report and in the unaudited condensed consolidated financial statements included in our Quarterly Report on Form 10-Q for the quarterly period ended March 31, 2017. Subsequent Events. The Company has evaluated subsequent events for recognition and disclosure for occurrences and transactions after the date of the unaudited condensed consolidated financial statements dated as of June 30, 2017.

(1) Description of Business, Basis of Presentation, and Summary of Significant Accounting Policies

Description of Business. Primerica, Inc. (the "Parent Company"), together with its subsidiaries (collectively, "we", "us" or the "Company"), is a leading distributor of financial products to middle-income households in the United States and Canada. We assist our clients in meeting their needs for term life insurance, which we underwrite, and mutual funds, annuities, managed investments and other financial products, which we distribute primarily on behalf of third parties. Our primary subsidiaries include the following entities: Primerica Financial Services, Inc. ("PFS"), a general agency and marketing company; Primerica Life Insurance Company ("Primerica Life"), our principal life insurance company; Primerica Financial Services (Canada) Ltd., a holding company for our Canadian operations, which includes Primerica Life Insurance Company of Canada ("Primerica Life Canada") and PFSL Investments Canada Ltd. ("PFSL Investments Canada"); and PFS Investments Inc. ("PFS Investments"), an investment products company and broker-dealer. Primerica Life, domiciled in Massachusetts, owns National Benefit Life Insurance Company ("NBLIC"), a New York insurance company. We established Peach Re, Inc. ("Peach Re") and Vidalia Re, Inc. (“Vidalia Re”) as special purpose financial captive insurance companies and wholly owned subsidiaries of Primerica Life. Peach Re and Vidalia Re have each entered into separate coinsurance agreements with Primerica Life whereby Primerica Life has ceded certain level-premium term life insurance policies to Peach Re and Vidalia Re (respectively, the “Peach Re Coinsurance Agreement” and the “Vidalia Re Coinsurance Agreement”).

Basis of Presentation. We prepare our financial statements in accordance with U.S. generally accepted accounting principles ("U.S. GAAP"). These principles are established primarily by the Financial Accounting Standards Board ("FASB"). The preparation of financial statements in conformity with U.S. GAAP requires us to make estimates and assumptions that affect financial statement balances, revenues and expenses and cash flows, as well as the disclosure of contingent assets and liabilities. Management considers available facts and knowledge of existing circumstances when establishing the estimates included in our financial statements.

The accompanying unaudited condensed consolidated financial statements contain all adjustments, generally consisting of normal recurring accruals, which are necessary to fairly present the balance sheets as of June 30, 2017 and December 31, 2016, the statements of income and comprehensive income (loss) for the three and six months ended June 30, 2017 and 2016, and the statements of stockholders' equity and cash flows for the six months ended June 30, 2017 and 2016. Results of operations for interim periods are not necessarily indicative of results for the entire year or of the results to be expected in future periods.

These unaudited condensed consolidated financial statements have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission ("SEC"). Certain information and note disclosures normally included in annual financial statements prepared in accordance with U.S. GAAP have been condensed or omitted pursuant to those rules and regulations, although the Company believes that the disclosures made are sufficient to make the information not misleading. These unaudited condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto that are included in our Annual Report on Form 10-K for the year ended December 31, 2016 ("2016 Annual Report").

Use of Estimates. The most significant items that involve a greater degree of accounting estimates and actuarial determinations subject to change in the future are the valuation of investments, deferred policy acquisition costs ("DAC"), liabilities for future policy benefits and unpaid policy claims, and income taxes. Estimates for these and other items are subject to change and are reassessed by management in accordance with U.S. GAAP. Actual results could differ from those estimates.

Consolidation. The accompanying unaudited condensed consolidated financial statements include the accounts of the Company and those entities required to be consolidated under applicable accounting standards. All material intercompany profits, transactions, and balances among the consolidated entities have been eliminated.

Reclassifications. Certain reclassifications have been made to prior-period amounts to conform to current-period reporting classifications. These reclassifications had no impact on net income or total stockholders' equity.

Significant Accounting Policies. All significant accounting policies remain unchanged from the 2016 Annual Report.

New Accounting Principles. In March 2016, the FASB issued Accounting Standards Update No 2016-09 (“ASU 2016-09”) Compensation—Stock Compensation (Topic 718) - Improvements to Employee Share-Based Payment Accounting. ASU 2016-09 intends to simplify several aspects of the accounting for share-based payment transactions, including the recognition of income tax consequences of awards, the classification of awards as either equity or liabilities, the method of recognizing award forfeitures, and the presentation of items within the statement of cash flows. The most notable impact on the Company’s financial statements involved the change in accounting for the income tax consequences associated with share-based payment transactions in the income statement. Prior to the adoption of ASU 2016-09, the tax effect of the difference between the cumulative compensation cost of a share-based award recognized for financial reporting purposes and the deduction of the award for tax purposes (“excess tax benefits or deficiencies”) was recognized as an adjustment to additional paid-in capital in the statement of stockholders’ equity. The amendments in ASU 2016-09 require that the excess tax benefits or deficiencies be recognized as a reduction to or an increase of income tax expense in the income statement. We adopted the amendments in ASU 2016-09 pertaining to excess tax benefits or deficiencies during the first quarter of 2017 on a prospective basis, which resulted in a reduction of income tax expense of approximately $0.9 million and $4.2 million for the excess tax benefit of share-based transactions for the three and six months ended June 30, 2017, respectively. ASU 2016-09 also changes the presentation of excess tax benefits or deficiencies in the cash flow statement from a financing activity to an operating activity. Therefore, we have presented the excess tax benefits or deficiencies as cash flows from operating activities within the accompanying consolidated statements of cash flows for all periods presented. The adoption of all other amendments outlined in ASU 2016-09 had either no impact to our financial statements or an immaterial impact to our financial statements.

Future Application of Accounting Standards. Recent accounting guidance not discussed above is not applicable, is immaterial to our financial statements, or did not or is not expected to have a material impact on our business. For additional information on new accounting pronouncements and recent accounting principles and their impact, if any, on our financial position or results of operations, see Note 1 (Description of Business, Basis of Presentation, and Summary of Accounting Policies) to our consolidated financial statements within our 2016 Annual Report and in the unaudited condensed consolidated financial statements included in our Quarterly Report on Form 10-Q for the quarterly period ended March 31, 2017.

Subsequent Events. The Company has evaluated subsequent events for recognition and disclosure for occurrences and transactions after the date of the unaudited condensed consolidated financial statements dated as of June 30, 2017.
