Preferred Providers Strength and Stability. When it comes to your retirement, you want to partner with companies that have a long history of meeting their obligations. Our leading insurance providers are committed to meeting the long-term needs and expectations of our customers. Not all insurance companies will work with insured pension plans, and not all contracts are suitable for use inside a defined benefit pension. We use insurance carriers with deep roots and solid ratings to provide the insured contracts within our plans, and have done extensive research to find annuity and life insurance contracts that are fully compatible with the requirements of the Internal Revenue Code.
