Business, Basis of Presentation and Summary of Significant Accounting Policies [Abstract]
Business, Basis of Presentation and Summary of Significant Accounting Policies	1. Business, Basis of Presentation and Summary of Significant Accounting Policies Business “MICC” or the “Company” refers to MetLife Insurance Company of Connecticut, a Connecticut corporation incorporated in 1863, and its subsidiaries, including MetLife Investors USA Insurance Company (“MLI-USA”). MetLife Insurance Company of Connecticut is a subsidiary of MetLife, Inc. (“MetLife”). The Company offers individual annuities, individual life insurance, and institutional protection and asset accumulation products. Basis of Presentation The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America (“GAAP”) requires management to adopt accounting policies and make estimates and assumptions that affect amounts reported in the interim condensed consolidated financial statements. In applying the Company's accounting policies, management makes subjective and complex judgments that frequently require estimates about matters that are inherently uncertain. Many of these policies, estimates and related judgments are common in the insurance and financial services industries; others are specific to the Company's businesses and operations. Actual results could differ from these estimates. The accompanying interim condensed consolidated financial statements include the accounts of MetLife Insurance Company of Connecticut and its subsidiaries, as well as partnerships and joint ventures in which the Company has control, and variable interest entities (“VIEs”) for which the Company is the primary beneficiary. Intercompany accounts and transactions have been eliminated. The Company uses the equity method of accounting for investments in equity securities in which it has a significant influence or more than a 20% interest and for real estate joint ventures and other limited partnership interests in which it has more than a minor equity interest or more than a minor influence over the joint venture's or partnership's operations, but does not have a controlling interest and is not the primary beneficiary. The Company uses the cost method of accounting for investments in real estate joint ventures and other limited partnership interests in which it has a minor equity investment and virtually no influence over the joint venture's or the partnership's operations. Certain amounts in the prior year periods' interim condensed consolidated financial statements have been reclassified to conform with the 2011 presentation. Such reclassifications include: • Reclassification from other net investment gains (losses) of $563 million and $255 million to net derivative gains (losses) in the interim condensed consolidated statements of operations for the three months and six months ended June 30, 2010, respectively; • Reclassifications related to operating revenues and expenses that affected results of operations on a segment and consolidated basis. See Note 8. Since the Company is a member of a controlled group of affiliated companies, its results may not be indicative of those of a stand-alone entity. The accompanying interim condensed consolidated financial statements reflect all adjustments (including normal recurring adjustments) necessary to present fairly the consolidated financial position of the Company at June 30, 2011, its consolidated results of operations for the three months and six months ended June 30, 2011 and 2010, its consolidated statements of stockholders' equity for the six months ended June 30, 2011 and 2010, and its consolidated statements of cash flows for the six months ended June 30, 2011 and 2010, in conformity with GAAP. Interim results are not necessarily indicative of full year performance. The December 31, 2010 consolidated balance sheet data was derived from audited consolidated financial statements included in MetLife Insurance Company of Connecticut's Annual Report on Form 10-K for the year ended December 31, 2010 (the “2010 Annual Report”), filed with the U.S. Securities and Exchange Commission, which include all disclosures required by GAAP. Therefore, these interim condensed consolidated financial statements should be read in conjunction with the consolidated financial statements of the Company included in the 2010 Annual Report. Adoption of New Accounting Pronouncements Effective January 1, 2011, the Company adopted new guidance that addresses when a business combination should be assumed to have occurred for the purpose of providing pro forma disclosure. Under the new guidance, if an entity presents comparative financial statements, the entity should disclose revenue and earnings of the combined entity as though the business combination that occurred during the current year had occurred as of the beginning of the comparable prior annual reporting period. The guidance also expands the supplemental pro forma disclosures to include additional narratives. The adoption did not have an impact on the Company's consolidated financial statements. Effective January 1, 2011, the Company adopted new guidance regarding goodwill impairment testing. This guidance modifies Step 1 of the goodwill impairment test for reporting units with zero or negative carrying amounts. For those reporting units, an entity would be required to perform Step 2 of the test if qualitative factors indicate that it is more likely than not that goodwill impairment exists. The adoption did not have an impact on the Company's consolidated financial statements. Effective January 1, 2011, the Company adopted new guidance regarding accounting for investment funds determined to be VIEs. Under this guidance, an insurance entity would not be required to consolidate a voting-interest investment fund when it holds the majority of the voting interests of the fund through its separate accounts. In addition, an insurance entity would not consider the interests held through separate accounts for the benefit of policyholders in the insurer's evaluation of its economics in a VIE, unless the separate account contractholder is a related party. The adoption did not have a material impact on the Company's consolidated financial statements. Future Adoption of New Accounting Pronouncements In June 2011, the Financial Accounting Standards Board (“FASB”) issued new guidance regarding comprehensive income (Accounting Standards Update (“ASU”) 2011-05, Comprehensive Income (Topic 220): Presentation of Comprehensive Income), effective for fiscal years, and interim periods within those years, beginning after December 15, 2011. The guidance should be applied retrospectively and early adoption is permitted. The new guidance provides companies with the option to present the total of comprehensive income, components of net income, and the components of other comprehensive income either in a single continuous statement of comprehensive income or in two separate but consecutive statements. The objective of the standard is to increase the prominence of items reported in other comprehensive income and to facilitate convergence of GAAP and International Financial Reporting Standards (“IFRS”). The standard eliminates the option to present components of other comprehensive income as part of the statement of changes in stockholders' equity. The Company is currently evaluating the impact of this guidance on its consolidated financial statements. In May 2011, the FASB issued new guidance regarding fair value measurement (ASU 2011- 04, Fair Value Measurement (Topic 820): Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and IFRSs), effective for the first interim or annual period beginning after December 15, 2011. The guidance should be applied prospectively. The amendments in this ASU are intended to establish common requirements for measuring fair value and for disclosing information about fair value measurements in accordance with GAAP and IFRS. Some of the amendments clarify the FASB's intent on the application of existing fair value measurement requirements. Other amendments change a particular principle or requirement for measuring fair value or for disclosing information about fair value measurements. The Company is currently evaluating the impact of this guidance on its consolidated financial statements. In April 2011, the FASB issued new guidance regarding effective control in repurchase agreements (ASU 2011-03, Transfers and Servicing (Topic 860): Reconsideration of Effective Control for Repurchase Agreements), effective for the first interim or annual period beginning on or after December 15, 2011. The guidance should be applied prospectively to transactions or modifications of existing transactions that occur on or after the effective date. The amendments in this ASU remove from the assessment of effective control the criterion requiring the transferor to have the ability to repurchase or redeem the financial assets. The Company is currently evaluating the impact of this guidance on its consolidated financial statements. In April 2011, the FASB issued new guidance regarding accounting for troubled debt restructuring (ASU 2011-02, Receivables (Topic 310): A Creditor's Determination of Whether a Restructuring Is a Troubled Debt Restructuring), effective for the first interim or annual period beginning on or after June 15, 2011 and which should be applied retrospectively to the beginning of the annual period of adoption. This guidance clarifies whether a creditor has granted a concession and whether a debtor is experiencing financial difficulties for the purpose of determining when a restructuring constitutes a troubled debt restructuring. The Company does not expect the adoption of this guidance to have a material impact on its consolidated financial statements and related disclosures. In October 2010, the FASB issued new guidance regarding accounting for deferred acquisition costs (ASU 2010-26, Financial Services— Insurance (Topic 944): Accounting for Costs Associated with Acquiring or Renewing Insurance Contracts) effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2011. The guidance should be applied prospectively upon adoption. Retrospective application to all prior periods presented upon the date of adoption also is permitted, but not required. This guidance clarifies the costs that should be deferred by insurance entities when issuing and renewing insurance contracts. The guidance also specifies that only costs related directly to successful acquisition of new or renewal contracts can be capitalized. All other acquisition-related costs should be expensed as incurred. The Company is currently evaluating the impact of this guidance on its consolidated financial statements and related disclosures.

Business, Basis of Presentation and Summary of Significant Accounting Policies

1. Business, Basis of Presentation and Summary of Significant Accounting Policies

Business

“MICC” or the “Company” refers to MetLife Insurance Company of Connecticut, a Connecticut corporation incorporated in 1863, and its subsidiaries, including MetLife Investors USA Insurance Company (“MLI-USA”). MetLife Insurance Company of Connecticut is a subsidiary of MetLife, Inc. (“MetLife”). The Company offers individual annuities, individual life insurance, and institutional protection and asset accumulation products.

Basis of Presentation

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America (“GAAP”) requires management to adopt accounting policies and make estimates and assumptions that affect amounts reported in the interim condensed consolidated financial statements.

In applying the Company's accounting policies, management makes subjective and complex judgments that frequently require estimates about matters that are inherently uncertain. Many of these policies, estimates and related judgments are common in the insurance and financial services industries; others are specific to the Company's businesses and operations. Actual results could differ from these estimates.

The accompanying interim condensed consolidated financial statements include the accounts of MetLife Insurance Company of Connecticut and its subsidiaries, as well as partnerships and joint ventures in which the Company has control, and variable interest entities (“VIEs”) for which the Company is the primary beneficiary. Intercompany accounts and transactions have been eliminated.

The Company uses the equity method of accounting for investments in equity securities in which it has a significant influence or more than a 20% interest and for real estate joint ventures and other limited partnership interests in which it has more than a minor equity interest or more than a minor influence over the joint venture's or partnership's operations, but does not have a controlling interest and is not the primary beneficiary. The Company uses the cost method of accounting for investments in real estate joint ventures and other limited partnership interests in which it has a minor equity investment and virtually no influence over the joint venture's or the partnership's operations.

Certain amounts in the prior year periods' interim condensed consolidated financial statements have been reclassified to conform with the 2011 presentation. Such reclassifications include:

• Reclassification from other net investment gains (losses) of $563 million and $255 million to net derivative gains (losses) in the interim condensed consolidated statements of operations for the three months and six months ended June 30, 2010, respectively;

• Reclassifications related to operating revenues and expenses that affected results of operations on a segment and consolidated basis. See Note 8.

Since the Company is a member of a controlled group of affiliated companies, its results may not be indicative of those of a stand-alone entity.

The accompanying interim condensed consolidated financial statements reflect all adjustments (including normal recurring adjustments) necessary to present fairly the consolidated financial position of the Company at June 30, 2011, its consolidated results of operations for the three months and six months ended June 30, 2011 and 2010, its consolidated statements of stockholders' equity for the six months ended June 30, 2011 and 2010, and its consolidated statements of cash flows for the six months ended June 30, 2011 and 2010, in conformity with GAAP. Interim results are not necessarily indicative of full year performance. The December 31, 2010 consolidated balance sheet data was derived from audited consolidated financial statements included in MetLife Insurance Company of Connecticut's Annual Report on Form 10-K for the year ended December 31, 2010 (the “2010 Annual Report”), filed with the U.S. Securities and Exchange Commission, which include all disclosures required by GAAP. Therefore, these interim condensed consolidated financial statements should be read in conjunction with the consolidated financial statements of the Company included in the 2010 Annual Report.

The guidance should be applied prospectively.

The Company is currently evaluating the impact of this guidance on its consolidated financial statements.

In April 2011, the FASB issued new guidance regarding effective control in repurchase agreements (ASU 2011-03, Transfers and Servicing (Topic 860): Reconsideration of Effective Control for Repurchase Agreements), effective for the first interim or annual period beginning on or after December 15, 2011. The guidance should be applied prospectively to transactions or modifications of existing transactions that occur on or after the effective date. The amendments in this ASU remove from the assessment of effective control the criterion requiring the transferor to have the ability to repurchase or redeem the financial assets. The Company is currently evaluating the impact of this guidance on its consolidated financial statements.

In April 2011, the FASB issued new guidance regarding accounting for troubled debt restructuring (ASU 2011-02, Receivables (Topic 310): A Creditor's Determination of Whether a Restructuring Is a Troubled Debt Restructuring), effective for the first interim or annual period beginning on or after June 15, 2011 and which should be applied retrospectively to the beginning of the annual period of adoption. This guidance clarifies whether a creditor has granted a concession and whether a debtor is experiencing financial difficulties for the purpose of determining when a restructuring constitutes a troubled debt restructuring. The Company does not expect the adoption of this guidance to have a material impact on its consolidated financial statements and related disclosures.

In October 2010, the FASB issued new guidance regarding accounting for deferred acquisition costs (ASU 2010-26, Financial Services— Insurance (Topic 944): Accounting for Costs Associated with Acquiring or Renewing Insurance Contracts) effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2011. The guidance should be applied prospectively upon adoption. Retrospective application to all prior periods presented upon the date of adoption also is permitted, but not required. This guidance clarifies the costs that should be deferred by insurance entities when issuing and renewing insurance contracts. The guidance also specifies that only costs related directly to successful acquisition of new or renewal contracts can be capitalized. All other acquisition-related costs should be expensed as incurred. The Company is currently evaluating the impact of this guidance on its consolidated financial statements and related disclosures.
