Item 1.01 Entry into a Material Definitive Agreement.

On February 4, 2013, Connecticut General Life Insurance Company ("CGLIC"), a subsidiary of Cigna Corporation ("Cigna"), entered into a Master Transaction Agreement and related agreements (the "Agreements") with Berkshire Hathaway Life Insurance Company of Nebraska ("Berkshire Life") and National Indemnity Company, the parent of Berkshire Life ("NICO"). Pursuant to the Agreements, CGLIC ceded to Berkshire Life liabilities for variable annuity reinsurance contracts related to guaranteed minimum death benefits and guaranteed minimum income benefits up to an approximately $4 billion aggregate limit.

Cigna will fund this transaction with an incremental $100 million of parent company cash, approximately $1.8 billion of the investment assets dedicated in support of the run-off businesses, and an estimated $300 million tax benefit associated with the transaction - resulting in a total reinsurance premium of $2.2 billion in cash to Berkshire Life. One-third of the premium was paid on February 4, 2013 and, during the period ending April 30, 2013, CGLIC will pay the balance of the premium with interest on the remaining balance at 1.25% per annum. Interest will cease to accrue on any funds CGLIC transfers to Berkshire Life before April 30, 2013.

Following payment of the premiums, Berkshire Life and NICO will fund a trust account as security for CGLIC of Berkshire Life's reinsurance obligations and NICO's surety obligations. NICO also issued to CGLIC a surety policy. Under the Agreements, Berkshire Life will have the option to substitute eligible assets for cash in the trust account.

The transaction does not cover liabilities already subject to other third party reinsurance arrangements. While CGLIC currently retains the administration of the reinsured business, Berkshire Life may elect to assume administration under the Agreements.

The Agreements include customary representations, warranties and covenants of CGLIC, Berkshire Life and NICO, including but not limited to, corporate authority, confidentiality and cooperation in administration, reporting or related actions contemplated by the Agreements. CGLIC also made a limited representation with respect to the claims data and coding in its proprietary valuation model. The Agreements contain certain indemnification obligations and penalties for breach of the representations, warranties and/or covenants, including termination of coverage in the event of non-payment of the reinsurance premium.
