The investment period is the contractual phase of a private fund during which the general partner is authorized to call capital from LPs for new investments — primarily initial portfolio company stakes.

How it works

Limited partnership agreements define investment period length — commonly five years from final close, sometimes extendable by GP with LP consent. During this window, the GP calls capital for new deals, management fees, and expenses. Follow-on investments in existing portfolio companies may be permitted after the period ends, but new platform investments are restricted. When the period expires without extension, the fund enters harvest period focus. GPs approaching period end face deployment pressure on remaining dry powder — a dynamic founders sometimes exploit in negotiations. Investment period differs from fund term — total fund life including extensions may run 10–12 years while investment period covers only the front portion.

Why it matters

• LPs: Monitor pacing — slow deployment early may signal selectivity or weak deal flow; rushed late deployment raises quality concerns.
• GPs: Fundraising for the next vintage often overlaps with the tail of the prior fund’s investment period; LP questions focus on remaining capacity.

Common mistake

Confusing investment period end with fund liquidation. Funds routinely hold assets years after the investment period closes.
