- Royalty interests carry zero operational cost exposure and lower risk, but meaningfully lower total returns.
- Both structures receive the 15% depletion allowance, but on different income bases.

Direct Participation Program
Working Interest
Direct ownership in drilling and production. Qualifies for IDC deductions (60-85% Year-1), 15% depletion, and TDC depreciation. Higher risk, higher upside, best tax treatment.
Royalty Interest
Passive Mineral Rights
Fixed percentage of gross revenue. No drilling costs, no operating expenses, no liability. Receives 15% depletion but no IDC deductions. Lower risk, predictable cash flow.

Royalty WinsIllustrative only. DPP model: 75% IDC Year 1, 15% annual depletion, 7-year MACRS TDC, 18% Year-1 gross yield, 35% hyperbolic decline (b=1.2). Royalty model: 7% gross yield, 8% annual decline, 15% depletion, no IDC. All after-tax figures use the marginal rate shown. Nominal, pre-inflation. Oil and gas involves risk of total loss. IDC deductibility requires material participation; consult a CPA. IRR is a numerical approximation. Not a solicitation. Accredited investors only.
