Trade-off Theory

Capital Structure

Turkish: Denkleştirme Teorisi

Short definition

Trade-off theory balances the tax-shield benefit of debt against distress and bankruptcy costs. It implies an interior leverage band; it is a rival narrative to pecking-order.

Detailed explanation

The marginal shield stops when tax capacity is used up; marginal distress rises with cash volatility and asset specificity. Collateralised, cash-stable businesses carry more debt.

Dynamic trade-off allows a miss to persist because adjustment (issue costs, covenants) is costly. High rates look like a larger shield and also raise cash Kd and default probability.

Why it matters for the CFO

Target leverage and the rating conversation rest on this balance. Counting only the shield leaves distress cost outside WACC.

How to read it

The optimum is the net of shield PV minus distress PV minus lost flexibility. One year of interest deduction is not a sustainable balance.
