Leverage and Regulatory Limits
BDCs are regulated under the 1940 Act, which limits leverage. Historically the limit was 1:1 debt-to-equity (200% asset coverage). The 2018 Small Business Credit Availability Act reduced required asset coverage to 150%, allowing 2:1 debt-to-equity for BDCs whose boards or shareholders approve.
Higher leverage amplifies yield in good times and accelerates NAV destruction in bad times. 2008 wiped out several over-levered BDCs; 2020 stressed more.

§ 03Try it
In ARCC's filings, find the asset coverage ratio. Anything below 165-170% means cushion is thin and a downturn could force forced asset sales.
§ 04Key insight
With 1.5x debt-to-equity, every dollar of equity supports $2.50 of assets. A 10% asset value loss = $0.25 hit per dollar of equity = ~25% NAV decline. This is why BDC leverage matters so much. Pre-2008, several BDCs ran 1.5-2x and were wiped out when credit spreads widened. Always pair the headline leverage ratio with the asset coverage ratio (200% pre-2018, 150% post-SBCAA) — when asset coverage gets within 10-15 points of the regulatory floor, forced asset sales become a realistic risk in the next downturn.
§ 05Check-in
A BDC just increased regulatory leverage from 1.2x to 1.7x (debt/equity). Management says this boosts ROE. Honest assessment?

Sit with the ideas.
A BDC operates at 1.5x debt-to-equity. The portfolio loses 10% of value. Roughly what happens to NAV per share?
