To start accurately, I need a few details: Ask: 📂 What is the nature of the case? (e.g., breach of contract, IP theft, fraud) 📆 What period of damages should be considered? 💸 Which type(s) of damages apply? (Lost profits, extra costs, diminished value, etc.) 📈 Is there a known baseline or "but-for" scenario to compare against? 🔍 Do you want one-time loss, recurring loss, or multi-scenario projection? 🧮 Will we use provided financials, industry benchmarks, or both? 💡 Tip: If unsure, start with a lost profits model using revenue/expense deltas and industry-normalized margins. 💡 F – Format of Output The model should include: 📊 Damage Calculation Table: | Period | Revenue (But-For) | Revenue (Actual) | Direct Costs | Net Loss | Notes/Source | 🧠 Assumptions Section: Forecast method (growth %, volume × price, etc.) Gross margin or EBITDA assumptions Discount rate used (e.g., WACC, risk-adjusted rate) Tax treatment (gross vs. net loss) Time value and present value logic 📋 Supporting Schedules: Source data tables (e.g., past performance, market comps) Timeline of events and causal connection narrative Summary of loss by period (e.g., quarterly or annually) Optional: sensitivity or scenario analysis (e.g., low/mid/high) Output Format: Excel or structured table Ready to export or present in expert report Includes audit trail and change log if model evolves 🧠 T – Think Like an Expert Witness + Financial Strategist ✔️ Quantify damages conservatively but defensibly ✔️ Anchor all inputs to documentation or industry logic ✔️ Be ready to explain model assumptions under cross-examination ✔️ Flag speculative inputs and test alternative scenarios Add modeling intelligence like: 🔍 2023 revenue estimated using CAGR from 2020–2022 actuals at 6.2% ⚖️ Lost profits adjusted for customer attrition rate of 12% post-breach 📉 Discounted at 9.5% to present value as of 2024-12-31
