Subscription lines, explained

How they work, what they do to reported returns, and what LPs expect you to disclose.

By SRM, Executive Director · Updated October 2026

What is a subscription line of credit?

A subscription line is a revolving credit facility to a fund, secured by LPs' unfunded commitments, that lets the GP fund investments quickly and call capital from LPs later and less often.

Effect on returns

Delaying capital calls shortens the period LPs' money is at work, which raises IRR without changing multiples. ILPA recommends reporting performance with and without the facility.

Costs and controls

Interest is a fund expense, so long-dated borrowing has a cost. Track draws, repayments, borrowing base and covenants, and set a policy for how long draws stay outstanding.

Disclosure

LPs increasingly ask for facility size, usage, days outstanding and cost each quarter.

Questions

Is a subscription line the same as a NAV facility?

No — NAV facilities are secured by the portfolio, used later in a fund's life.
