--- name: capital-structure-optimizer description: "Evaluates the optimal debt-to-equity mix for a company by modeling how leverage changes affect WACC, EPS, credit rating, and financial flexibility, then recommends a target capital structure range with a clear trade-off summary. Use when deciding how much debt to carry, planning a recapitalization, preparing for a refinancing or rating review, or pressure-testing the balance sheet against strategic objectives." argument-hint: "[financials] [strategic-objective]" allowed-tools: ["Read"] --- # Capital Structure Optimizer ## Purpose Determine the debt/equity mix that minimizes the cost of capital while preserving the financial flexibility and credit profile the company actually needs — and translate that into a defensible target leverage range with quantified trade-offs. Replaces gut-feel leverage decisions and one-number "optimal WACC" answers with a range that accounts for rating thresholds, EPS sensitivity, and downside scenarios. ## When to Use Invoke this skill when the user asks to: - Decide how much debt to take on or pay down - Evaluate a recapitalization, dividend recap, or share buyback funded by debt - Pressure-test the balance sheet before an acquisition or major capex program - Prepare for a credit rating review or refinancing and assess headroom - Compare leverage against peers and decide on a target leverage ratio - Quantify the WACC and EPS impact of shifting the debt/equity mix ## Inputs Required Before starting, collect: - **Current capital structure**: Total debt, cash, market cap (or equity value), and any preferred/hybrid instruments - **Income statement basics**: Revenue, EBITDA, EBIT, net income, interest expense, diluted share count, effective tax rate - **Credit metrics**: Current credit rating (or implied), key covenants, and debt maturity profile - **Cost inputs**: Current cost of debt (blended interest rate), equity beta or estimated cost of equity, and risk-free rate if available - **Strategic objective**: What the company is solving for — lower WACC, fund growth, return capital, defend a rating, or maximize flexibility - **Cash flow profile**: Free cash flow trend, cyclicality, and capex intensity - **Constraints**: Target rating to maintain, maximum acceptable leverage, dividend commitments, or board-set guardrails If cost of equity is not provided, estimate it via CAPM using a reasonable equity risk premium (5–6%) and note the assumption. If rating is unknown, infer an implied rating from leverage and coverage metrics. ## Instructions ### Step 1: Baseline the Current Structure Establish the starting point before modeling any change: - Compute current **net debt / EBITDA**, **EBITDA / interest** (coverage), and **debt / total capital** (book and market) - Calculate current **WACC**: WACC = (E/V × Ke) + (D/V × Kd × (1 − tax rate)) - Record current **diluted EPS** and the implied or stated **credit rating** - Flag where the company sits relative to its stated constraints and target rating ### Step 2: Define the Leverage Scenarios Model a structured set of scenarios rather than a single point: - Build at least **5 leverage scenarios** spanning conservative to aggressive — e.g., net debt/EBITDA at roughly 0.5x, 1.5x, 2.5x, 3.5x, and 4.5x (calibrate the range to the company's sector norms) - For each scenario, derive the resulting debt and equity weights, incremental debt raised or repaid, and the assumed use of proceeds (buyback, debt paydown, growth) ### Step 3: Model the Cost of Debt Curve Cost of debt is not constant across leverage — step it up as risk rises: - Map each leverage scenario to a likely credit rating band using standard rating thresholds (e.g., investment grade typically below ~3.0–3.5x net debt/EBITDA with coverage above ~4x) - Assign a cost of debt to each rating band, widening the spread as leverage increases and the rating deteriorates - Note the **rating cliff** — the leverage level where the company crosses from investment grade to sub-investment grade, which materially repriced both debt and access to capital ### Step 4: Model the Cost of Equity Response As leverage rises, equity gets riskier: - Re-lever beta for each scenario using the Hamada relationship: βL = βU × (1 + (1 − tax) × D/E) - Recompute cost of equity (Ke) at each scenario via CAPM - This ensures WACC is not artificially minimized by ignoring the equity risk premium that leverage adds ### Step 5: Calculate WACC, EPS, and Credit Impact Per Scenario For each leverage scenario, produce: - **WACC** with the re-levered Ke and the rating-adjusted Kd - **Diluted EPS** — reflecting new interest expense (after tax) and any change in share count from buybacks or issuance - **Projected credit rating** and key metrics (net debt/EBITDA, interest coverage) - **Financial flexibility score** — qualitative High/Medium/Low based on covenant headroom, maturity concentration, and FCF coverage of debt service ### Step 6: Identify the Optimal Range Find the structure that balances the objective against risk: - Locate the WACC-minimizing scenario — but do **not** automatically recommend it if it crosses the rating cliff or eliminates flexibility - Define a **target range** (not a single number), typically a band of net debt/EBITDA where WACC is near its minimum, the desired rating holds, and FCF comfortably covers debt service through a downside case - Stress the recommended range against a downside scenario (e.g., EBITDA −20%) to confirm covenants and coverage still hold ### Step 7: Build the Trade-Off Summary Make the tension explicit. Summarize what is gained and given up moving across the range: - Lower WACC and EPS accretion (benefit of more debt) vs. rating risk, refinancing risk, and lost flexibility (cost of more debt) - State the single recommended target leverage range and the rationale, written for a board or finance committee ## Output Format - **Structure**: Narrative diagnosis, a scenario comparison table, and a final recommendation with trade-off summary - **Length**: 900–1,300 words - **Format**: Prose for analysis and recommendation; a scenario table comparing all leverage cases across WACC, EPS, rating, coverage, and flexibility - **Sections**: Current Structure Baseline → Scenario Comparison Table → WACC & Rating Analysis → EPS Impact → Recommended Target Range → Trade-Off Summary → Key Assumptions - **Tone**: CFO-to-board — quantitative, decisive, and explicit about assumptions and downside risk ## Quality Checklist Before delivering output, verify: - [ ] At least 5 leverage scenarios are modeled with distinct net debt/EBITDA levels - [ ] Cost of debt rises across scenarios and the investment-grade rating cliff is explicitly identified - [ ] Cost of equity is re-levered per scenario (beta does not stay constant as leverage changes) - [ ] The recommendation is a range, not a single point, and is justified against a downside EBITDA case - [ ] The scenario table reports WACC, EPS, rating, coverage, and flexibility for every case - [ ] Every non-provided input (cost of equity, ERP, implied rating) is flagged as an assumption ## Notes - The WACC-minimizing structure is rarely the right recommendation on its own — flexibility and rating headroom routinely justify carrying less debt than the math suggests, especially for cyclical businesses. - The rating cliff between investment grade and high yield is the most consequential threshold; the cost-of-capital and market-access penalty for crossing it usually outweighs marginal WACC gains. - Anchor the leverage range to sector norms — what is conservative for a regulated utility is aggressive for a software company. - If the strategic objective is funding growth or an acquisition, weight financial flexibility higher; if it is returning capital in a stable business, a tighter, more leveraged range is defensible. --- ## How to use this skill This file is a Claude Code skill in [Anthropic's standard format](https://docs.anthropic.com/en/docs/claude-code/skills) — markdown with YAML frontmatter at the top. **Installing in Claude Code:** - `~/.claude/skills//SKILL.md` — auto-loads in every session anywhere on your machine (recommended for skills you'll use across multiple projects) - `/.claude/skills//SKILL.md` — auto-loads only when working in that project (recommended for project-specific skills) Restart Claude Code or open a new session to register. **Using in Claude.ai, ChatGPT, Gemini, or other AI tools:** 1.
