(LNL), the lead operating company; Lincoln Life&Annuity Insurance Co. of New York (LLANY), an operating company; and Liberty Life Assurance Co. of Boston (LLACB), an operating company. The ratings also reflect LFG's projected maintenance of very strong capital adequacy, stable earnings, and exceptional liquidity.
