Understanding Economic Damages in Commercial Litigation
Economic damages, also called compensatory damages, are designed to make the injured party whole by compensating them for actual financial losses suffered due to another party's breach or wrongful conduct. Unlike punitive damages (which punish the wrongdoer) or nominal damages (which recognize a legal wrong without substantial harm), economic damages represent measurable financial harm.
The Purpose of Economic Damages
South Carolina follows the fundamental principle that damages should place the plaintiff in the position they would have occupied "but for" the defendant's wrongful conduct. This compensatory principle drives every aspect of damages calculation—we're not trying to punish the defendant or provide a windfall to the plaintiff, but rather to measure and restore what was lost.
For Greenville businesses engaged in commercial litigation, this means demonstrating not just that harm occurred, but quantifying that harm with sufficient specificity that a judge or jury can make a reasoned award.
Economic vs. Non-Economic Damages
Economic Damages (Measurable):
- Lost profits from business operations
- Lost revenue from interrupted contracts
- Diminished business value
- Increased operating costs
- Lost business opportunities
- Cost to repair or replace damaged property
- Out-of-pocket expenses incurred
The Role of the Forensic Accountant
Calculating economic damages requires specialized expertise that combines accounting knowledge, industry expertise, financial modeling, economic analysis, and understanding of the legal framework. This is where forensic accountants become invaluable. We don't just calculate numbers—we build defensible, well-documented analyses that withstand cross-examination and meet South Carolina's legal standards for damages proof.
South Carolina Legal Standards for Proving Damages
Before diving into calculation methodologies, it's essential to understand what South Carolina law requires to recover economic damages in commercial litigation. Even the most sophisticated financial analysis is worthless if it doesn't meet the legal standards for admissibility and persuasiveness.
Reasonable Certainty Standard
South Carolina courts require that damages be proven with "reasonable certainty." This doesn't mean absolute precision—the law recognizes that calculating damages often involves estimates and projections. However, damages cannot be speculative, conjectural, based on mere possibilities, or derived from guesswork.
Important Note:
The reasonable certainty standard means that damages must be established through credible evidence and sound methodology, even if the precise amount involves some degree of estimation. In practice, you cannot simply assert "we would have made significant profits"—you must demonstrate through historical performance, market analysis, and financial projections what those profits would reasonably have been.
Proximate Cause Requirement
Economic damages must be proximately caused by the defendant's wrongful conduct. This means the damages must be a direct and natural consequence of the wrong, the harm must be reasonably foreseeable, and the causal chain cannot be too remote or indirect.
Duty to Mitigate Damages
South Carolina law imposes a duty on the injured party to take reasonable steps to minimize their damages. The plaintiff cannot simply sit idle and allow damages to accumulate when reasonable mitigation is possible. Key principles include:
- Plaintiff must make reasonable efforts to mitigate
- Defendant bears burden of proving failure to mitigate
- Plaintiff need not take extraordinary measures
- Cost of mitigation efforts can be recovered
- Damages are reduced by amounts that could have been avoided
Types of Economic Damages in Commercial Cases
Commercial litigation in South Carolina encompasses numerous damage theories. Understanding which type of damages applies to your case is the first step in proper quantification.
1. Lost Profits
Lost profits represent the net income a business would have earned "but for" the defendant's wrongful conduct. This is the most common form of economic damages in commercial litigation.
Key Distinction: Lost profits are NET income (revenue minus variable costs), not gross revenue. A common error is claiming all lost revenue as damages without accounting for costs that wouldn't have been incurred.
2. Business Interruption Damages
Business interruption damages compensate for lost income when operations are disrupted due to property damage, supplier failure, or other interrupting events. Components include:
- Lost net profits during interruption period
- Continuing fixed expenses (rent, salaries, insurance)
- Extra expenses incurred to minimize interruption
- Time required to restore business to pre-interruption level
3. Diminished Business Value
When wrongful conduct permanently reduces the value of a business, the diminished value represents recoverable damages.
4. Intellectual Property Damages
IP infringement damages take several forms under South Carolina and federal law:
- Patent Infringement: Lost profits or reasonable royalty
- Trade Secret Misappropriation: Lost profits, unjust enrichment, or reasonable royalty
- Trademark Infringement: Lost profits, corrective advertising costs
The "But For" Analysis Framework
The cornerstone of economic damages analysis is the "but for" scenario—what would have happened if the wrongful conduct had not occurred? Every damages calculation compares actual performance against this hypothetical but-for scenario.
Components of But-For Analysis
1. Historical Performance Baseline
Analyze the business's historical financial performance to establish normal operating patterns including revenue trends, profit margins, seasonal patterns, and growth trajectories.
2. Industry and Market Conditions
The but-for scenario must account for market realities including industry growth rates, competitive dynamics, economic conditions, and market size analysis.
3. Business-Specific Factors
Consider management capabilities, capacity constraints, capital availability, key customer relationships, and competitive advantages or disadvantages.
4. Damage Period Definition
Clearly define when damages begin and end—the start date when wrongful conduct first caused harm and the end date when damages are complete.
Methodologies for But-For Analysis
Before-and-After Method
Compare performance before the wrongful event with performance after. Most appropriate when the business was stable before the event and the event caused a clear disruption.
Yardstick Method
Use a comparable business or market segment as a benchmark for what plaintiff's performance should have been. Useful when plaintiff's actual performance is completely disrupted or when comparable data exists.
Sales Projection Method
Use the plaintiff's pre-event business projections, validated and adjusted as necessary. Requires that projections were created before the dispute arose and are realistic and supportable.
Market Share Method
Project plaintiff's market share and apply to total market size to determine but-for performance. Particularly useful in IP infringement and unfair competition cases.
Lost Profits Calculation Methodologies
Lost profits represent the most common economic damages in South Carolina commercial litigation. Calculating lost profits requires sophisticated analysis that courts will scrutinize carefully.
Step-by-Step Lost Profits Calculation
Step 1: Calculate Lost Revenue
Use one of the but-for methodologies to project what revenues would have been absent the wrongful conduct. Consider growth trajectory, capacity constraints, customer commitments, market conditions, and competitive factors.
Step 2: Deduct Variable Costs
Only NET profits are recoverable. You must deduct all costs that would have been incurred to generate the lost revenue:
- Cost of goods sold (COGS)
- Direct labor tied to production/sales
- Sales commissions
- Shipping and freight costs
- Raw materials and supplies
- Variable utilities
Critical Concept:
Fixed costs that continue regardless (rent, administrative salaries, insurance, depreciation) are generally NOT deducted from lost revenue when calculating lost profits.
Step 3: Account for Mitigation
South Carolina law requires plaintiffs to mitigate damages. The calculation must reflect revenue earned from alternative sources, costs saved through mitigation, and any benefits realized from mitigation activities.
Step 4: Define Damage Period
Lost profits continue until the contract term would have ended, the business returns to but-for performance level, the business permanently stabilizes at a lower level, or the harm is otherwise remedied.
Present Value Considerations
When lost profits extend into future periods, they must be reduced to present value. This accounts for the time value of money, investment opportunity cost, inflation, and risk.
Business Interruption Claims
Business interruption damages compensate for lost income when operations are disrupted. While similar to lost profits, business interruption has unique characteristics requiring specialized analysis.
Components of Business Interruption Damages
1. Lost Net Income
The profits the business would have earned during the interruption period, calculated similar to lost profits analysis.
2. Continuing Fixed Expenses
Fixed costs that continue despite interruption: rent, insurance, salaried employees, loan payments, property taxes, equipment leases.
3. Extra Expenses
Costs incurred to minimize interruption: expedited repairs, temporary facilities, premium shipping, overtime pay, additional advertising.
4. Extended Business Interruption
Time required to rebuild customer base and return to pre-interruption performance levels after physical reopening.
Defining the Interruption Period
Accurately defining the interruption period is critical. Consider:
- Start Date: When operations first became impaired
- End Date: Physical restoration, operational restoration, or revenue restoration
- Extended Period: Time to rebuild customer relationships and market position
Intellectual Property Damages
Intellectual property infringement creates unique damages issues. South Carolina courts handle both state law trade secret cases and federal patent and trademark cases, each with distinct damage frameworks.
Patent Infringement Damages
Patent cases in federal court follow 35 U.S.C. § 284, providing for "damages adequate to compensate for the infringement, but in no event less than a reasonable royalty."
Lost Profits from Patent Infringement
Patent owner must prove:
- Demand for patented product existed
- Absence of acceptable non-infringing substitutes
- Manufacturing and marketing capability
- Amount of profit patent owner would have made
Reasonable Royalty
When lost profits can't be proven, patent owner is entitled to at least a reasonable royalty—the amount a willing licensee would pay for the right to use the patent. Courts consider the Georgia-Pacific factors to determine appropriate royalty rates.
Trade Secret Misappropriation (SC Uniform Trade Secrets Act)
South Carolina Code § 39-8-30 governs trade secret damages. Plaintiff can recover:
- Actual loss caused by misappropriation
- Unjust enrichment not captured by actual loss
- Reasonable royalty for unauthorized use
Diminished Business Value Analysis
When wrongful conduct permanently reduces a business's value, the diminution in value represents recoverable economic damages. This requires business valuation expertise.
When Diminished Value Claims Apply
- Loss of key customer relationships that won't be regained
- Destruction of competitive advantage
- Permanent market share loss
- Damage to business reputation affecting future earnings
- Loss of intellectual property providing lasting competitive edge
Business Valuation Approaches
Income Approach
Values business based on present value of future economic benefits. Most common for diminished value claims using discounted cash flow or capitalization methods.
Market Approach
Compares business to similar businesses that have sold. Uses market multiples applied to financial metrics.
Asset Approach
Values business based on underlying assets minus liabilities. Less common for damages as commercial businesses derive value from earnings, not assets.
Avoiding Double Recovery
Plaintiff cannot recover BOTH lost profits AND diminished value for the same harm. Choose either lost profits for specific period until harm ends, OR diminished value if harm is permanent.
The Expert Witness Process
When economic damages are disputed in South Carolina commercial litigation, forensic accountants typically serve as expert witnesses. Understanding this process helps attorneys and businesses work effectively with their experts.
Initial Engagement and Case Assessment
- Conflict Check: Ensure no conflicts of interest
- Initial Consultation: Discuss case facts and damages issues
- Engagement Letter: Define scope, fees, and timeline
- Early Assessment: Determine if damages can be calculated with reasonable certainty
Expert Report Requirements
For testifying experts in federal court and many state court cases, a comprehensive written report is required including:
- Complete statement of all opinions to be expressed
- Basis and reasons for each opinion
- Facts and data considered
- Exhibits to support opinions
- Expert qualifications and prior testimony
- Compensation for the case
Deposition and Trial Testimony
After reports are exchanged, experts typically face deposition by opposing counsel. During trial, experts present findings through direct examination, withstand cross-examination, and may be rehabilitated on re-direct.
Expert Witness Standards
South Carolina State Courts: Jones-Council standard under SC Rule of Evidence 702
Federal District Court: Daubert standard under Federal Rule of Evidence 702
Both require qualified expert, reliable methodology, and testimony that assists factfinder.

Frequently Asked Questions
Q: How are economic damages different from punitive damages?
Economic damages compensate for actual financial losses suffered—they're designed to make the plaintiff whole. Punitive damages are intended to punish the defendant for particularly egregious conduct. South Carolina allows punitive damages only in specific circumstances and caps them at three times compensatory damages or $500,000, whichever is greater.
Q: Can I recover lost profits if my business is new?
It's more challenging but not impossible. South Carolina courts require proving lost profits with reasonable certainty, which is harder for new businesses lacking historical performance. You'll need strong evidence including detailed business plans, industry analysis, market data, specific customer commitments, and management with relevant track record.
Q: What's the statute of limitations for commercial lawsuits in SC?
For breach of written contracts: 3 years. For breach of oral contracts: 3 years. For fraud: 3 years from discovery. For unfair trade practices: 3 years. Time begins running from when the breach occurred or was discovered. Consult an attorney promptly as these deadlines are strictly enforced.
Q: Do I need to hire a forensic accountant for damages?
For significant damages claims in commercial litigation, expert testimony is typically necessary. While parties can testify about their own losses, complex damages calculations require expert analysis to meet the "reasonable certainty" standard. Courts find expert testimony more credible than self-interested party testimony.
Q: How much does a forensic accountant cost?
Hourly rates in Greenville typically range $200-$450. Total costs might range from $15,000 for straightforward calculations to $50,000-$100,000+ for complex cases with business valuation. Early consultation can help estimate costs for your specific case.
Q: How does the duty to mitigate damages work?
South Carolina law requires plaintiffs to take reasonable steps to minimize damages after a breach. You can't allow damages to accumulate if reasonable alternatives exist. However, you're not required to take extraordinary measures. The defendant bears the burden of proving failure to mitigate. Document all mitigation attempts to show you acted reasonably.
