## Facts

- American Mutual Life Insurance Company, a mutual life insurer, was required by state law to maintain actuarial reserves to pay policy benefits.
- For tax years 1962–1981, American Mutual had net increases in life-insurance reserves and deducted those increases under the Internal Revenue Code provisions governing life insurers.
- In later years, American Mutual’s reserves decreased; under the life-insurance company tax rules, net reserve decreases (“releases”) were included in income.
- American Mutual sought refunds, arguing that portions of later reserve decreases should be excluded from income under I.R.C. § 111 (tax-benefit rule) because some earlier reserve-increase deductions allegedly produced no tax benefit in low- or zero-income years.
- The Court of Federal Claims granted summary judgment for the United States, finding American Mutual received tax benefits from the prior deductions and that reserve releases were not “fundamentally inconsistent” with the prior deductions.
- American Mutual appealed to the Federal Circuit.

## Issues

1. Whether American Mutual’s prior deductions for reserve increases yielded tax benefits such that § 111’s exclusionary aspect could not apply.
2. Whether later reserve decreases constitute a “fundamentally inconsistent” recovery event that triggers the tax-benefit rule and permits exclusion from income.

## Decision

- The Federal Circuit affirmed summary judgment for the United States.
- The court held American Mutual’s reserve-increase deductions yielded tax benefits.
- The court held later reserve decreases were not “fundamentally inconsistent” with the premise of the earlier reserve-increase deductions.
- American Mutual was required to include reserve decreases in taxable income and could not exclude any portion under § 111 or the tax-benefit rule.

## Legal Principles

- The tax-benefit rule applies only when a later event is sufficiently inconsistent with the premise of an earlier deduction to require an adjustment (“fundamental inconsistency”).
- I.R.C. § 111’s exclusionary aspect does not permit exclusion of a later recovery from income when the prior deduction produced a tax benefit.
- Routine changes in life-insurance reserves reflected in statutory reserve increases and decreases are treated under the specialized life-insurance tax regime; general doctrines like the tax-benefit rule do not override that regime absent the required inconsistency.
- A reserve decrease that reflects ordinary actuarial and policy experience does not negate the original premise that reserves were needed when deducted.

## Conclusion

The Federal Circuit held that reserve releases by a life insurer must be included in income because the insurer previously received tax benefits from reserve-increase deductions and later reserve decreases are not a fundamentally inconsistent “recovery” that would permit exclusion under § 111.
