Willis Towers Watson Financial Model

• Total assets: Approximately $30-35 billion.
• Key asset categories: Fiduciary assets (premiums collected from clients but not yet remitted to insurers) are a massive component, alongside accounts receivable and goodwill.
• Goodwill & intangibles: Represent a high percentage of total assets (often exceeding 30%) due to the historical Willis and Towers Watson merger and continuous bolt-on acquisitions.
• Working capital profile:
• Days Sales Outstanding (DSO): Typically 60-70 days.
• Days Inventory Outstanding (DIO): Not applicable.
• Days Payable Outstanding (DPO): Typically 30-40 days for operating payables.
• Net working capital as % of revenue: Often appears heavily skewed due to the matching of fiduciary assets and fiduciary liabilities.
• Is working capital positive or negative: Operating working capital is generally positive. The company holds client funds temporarily, generating interest income which flows directly to the bottom line.
• PP&E: Minimal due to the asset-light model. Mostly consists of leasehold improvements and IT equipment.
• Right-of-use assets: Material due to a vast global office footprint required for local client coverage.

• Capex as % of revenue: 2.0-2.5% (approximately $230-250 million annually).
• Maintenance capex vs. growth capex: Heavily skewed towards growth, specifically capitalised software development for platforms like Radar and LifeSight.
• Major capex programmes: Continuous investment in data analytics, artificial intelligence tools for risk modelling, and client-facing digital portals.
• Capitalised software: Highly material and represents the majority of the capital expenditure cash outflow.
• M&A pattern: Serial bolt-on acquirer targeting niche expertise, regional presence, or technology (such as the Newfront acquisition).
• Typical acquisition multiple paid: 10-15x EV/EBITDA for high-quality brokerage and advisory assets.

• Total debt: Approximately $4.7 billion in long-term debt.
• Debt/EBITDA ratio: Target range of 2.0x to 2.5x.
• Credit rating: Investment grade (typically BBB/Baa2).
• Key debt instruments: Senior unsecured notes with staggered maturities and a revolving credit facility for liquidity.
• Maturity profile: Well-laddered with average maturities exceeding 5 years.
• Interest rate profile: Predominantly fixed-rate bonds, insulating the company from short-term rate spikes.
• Covenants: Standard interest coverage and leverage ratio covenants, with significant headroom.
• Share repurchase programme: Highly active. The company repurchased $1.65 billion in shares in 2025 and $901 million in 2024.
• Dividend policy: Progressive dividend policy yielding approximately 1.2-1.5%, with a payout ratio of roughly 20-25% of adjusted earnings.

• Operating cash flow conversion: OCF / Net Income is often greater than 1.5x due to high non-cash charges (amortisation, stock-based compensation) and the timing of fiduciary settlements.
• Free cash flow margin: 15.9% in 2025 (Free Cash Flow of $1.55 billion on $9.7 billion revenue).
• Major non-cash items: Amortisation of acquisition intangibles, depreciation, and periodic impairment charges (such as the TRANZACT write-down).
• Working capital cash flow impact: The timing of fiduciary fund settlements can cause significant quarter-to-quarter volatility in operating cash flow.
• Capex intensity: Very low, resulting in exceptionally strong cash conversion.
• Cash tax rate vs. GAAP effective tax rate: Cash taxes are generally aligned with the adjusted effective tax rate of 21-22%, though GAAP rates fluctuate wildly during impairment years.

1. Assumptions: Hardcoded drivers for organic growth, margins, tax rate, share repurchases, and foreign exchange impacts.
2. Scenarios: Base, Bull, and Bear cases for P&C pricing cycles and interest rate environments.
3. Revenue Build: Segment-level build for HWC and R&B, explicitly stripping out TRANZACT historicals for pro-forma comparability.
4. Income Statement: Mirroring WTW's reporting structure (Salaries and benefits, Other operating expenses, Depreciation, Amortisation, Restructuring costs, Interest expense).
5. Fiduciary Funds Schedule: Tracking fiduciary assets, fiduciary liabilities, and the resulting fiduciary investment income based on short-term interest rates.
6. Balance Sheet: Assets (Cash, Fiduciary assets, Receivables, Goodwill) and Liabilities (Fiduciary liabilities, Payables, Debt).
7. Cash Flow Statement: Operating, Investing, and Financing cash flows, highlighting share repurchases and capitalised software additions.
8. Debt Schedule: Tranche-by-tranche bond maturities, revolving credit facility drawdowns, and interest expense calculation.
9. DCF Valuation: Unlevered free cash flow build, WACC calculation, and terminal value derivation.
10. Outputs & Charts: Summary dashboard of adjusted EPS, operating margins, and free cash flow conversion.

1. HWC Revenue = Prior Year HWC Revenue * (1 + HWC Organic Growth + FX Impact + M&A Impact)
2. R&B Revenue = Prior Year R&B Revenue * (1 + R&B Organic Growth + FX Impact + M&A Impact)
3. Total Revenue = HWC Revenue + R&B Revenue + Corporate/Unallocated Revenue
4. Salaries and Benefits = Total Revenue * Salaries and Benefits Margin (historically 54-56%)
5. Fiduciary Investment Income = Average Fiduciary Assets * Average Short-Term Yield
6. Adjusted Operating Income = Total Revenue - Salaries and Benefits - Other Operating Expenses - Depreciation - Amortisation (excluding transaction and transformation costs)
7. Adjusted Operating Margin = Adjusted Operating Income / Total Revenue
8. Free Cash Flow = Cash Flows from Operating Activities - Additions to Fixed Assets and Capitalised Software
9. Shares Outstanding = Prior Period Shares - (Share Repurchase Amount / Average Share Price)
10. Adjusted Diluted EPS = Adjusted Net Income / Diluted Shares Outstanding

The Revenue Build feeds the top line of the Income Statement. Fiduciary asset balances on the Balance Sheet feed the Fiduciary Funds Schedule, which calculates interest income that flows back to the Income Statement. Net Income from the Income Statement is the starting point for the Cash Flow Statement. The Cash Flow Statement determines the cash balance and debt paydown or drawdown, which link back to the Balance Sheet. Share repurchases in the Cash Flow Statement reduce the share count in the Assumptions and Income Statement for EPS calculations. Circularity risk exists if share repurchases are modelled as a percentage of net income while interest expense depends on debt used to fund those repurchases.

Revenue and income items are modelled as positive numbers. Expenses (Salaries, Other operating expenses, Depreciation, Amortisation, Interest expense) are modelled as negative numbers in the Income Statement build to allow for simple summation. In the Cash Flow Statement, cash inflows are positive and cash outflows (capex, share repurchases, dividends) are negative. Balance Sheet assets are positive; liabilities and equity are positive.

1. Failing to adjust historical 2023 and 2024 revenue for the TRANZACT divestiture will artificially depress 2025 growth rates if not handled on a pro-forma basis.
2. Misunderstanding fiduciary funds is a common error; these are client monies and must be strictly segregated from operating cash in the balance sheet and cash flow statement.
3. Double-counting fiduciary investment income can occur if it is included in operating revenue rather than modelled as a separate line item.
4. Ignoring the impact of foreign exchange is dangerous; WTW generates significant revenue outside the US, making a constant-currency toggle essential.
5. Overestimating operating margins by failing to add back the normalisation of transformation costs which flattered adjusted metrics in 2024.
6. Mismodelling seasonality will break quarterly models; the first and fourth quarters are significantly larger for revenue and cash flow than the middle quarters due to insurance renewal cycles.
7. Underestimating the cash drag of capitalised software will inflate valuation; this is a real cash outflow that must be deducted to reach true Free Cash Flow.
8. Miscalculating the share count reduction is a major risk; WTW's aggressive buyback programme ($1.65 billion in 2025) has a massive impact on EPS growth and must be modelled dynamically.

1. Adjusted Operating Margin should be in the 22-25% range; flag if it drops below 20% or exceeds 26%.
2. Salaries and benefits must remain between 53% and 57% of total revenue.
3. Free Cash Flow margin should be greater than 15% based on 2025 performance.
4. Total Assets must equal Total Liabilities plus Equity in every projected period.
5. Fiduciary Assets should roughly equal Fiduciary Liabilities (usually within a 5% variance).
6. Debt/EBITDA should remain between 2.0x and 2.5x; flag if leverage exceeds 3.0x.
7. Effective tax rate should be modelled at 21-22% for adjusted earnings.
8. Capex (including capitalised software) should not exceed 3% of revenue.
