Great Western purchased another insurance firm.

The Beverly Hills-based financial-services giant said it acquired United Fidelity Life Insurance Co. for an undisclosed amount. United, a 64-year-old firm based in Fort Worth, operates in 40 states and manages insurance policies worth about $4 billion. Great Western Financial, with assets of $23.5 billion, said United Fidelity will dovetail well with its other insurance operations.
