California Code, Revenue and Taxation Code - RTC § 24677

(a) If an amount representing damages is received or accrued by a corporation during a taxable year as a result of an award in a civil action for breach of contract or breach of a fiduciary duty or relationship, then the tax attributable to the inclusion in gross income for the taxable year of that part of the amount that would have been received or accrued by the corporation in a prior taxable year or years but for the breach of contract, or breach of a fiduciary duty or relationship, shall not be greater than the aggregate of the increases in taxes that would have resulted had that part been included in gross income for that prior taxable year or years.

(b) A corporation in computing the tax shall be entitled to deduct all credits and deductions for depletion, depreciation, and other items to which it would have been entitled, had the income been received or accrued by the corporation in the year during which it would have received or accrued it, except for the breach of contract or for the breach of fiduciary duty or relationship. The credits, deductions, or other items referred to in the prior sentence, attributable to property, shall be allowed only with respect to that part of the award which represents the corporation's share of income from the actual operation of the property.

(c) Subdivision (a) shall not apply unless the amount representing damage is three thousand dollars ($3,000) or more.
