During the commitment period, capital is gradually called by the manager in tranches for deployment into investments. It’s common in private market funds where immediate full investment is impractical. The duration can range from 12 months to several years, depending on strategy. After this period, uncalled capital may be returned or converted to committed capital. This schedule impacts fund cash flow modeling, drawdown planning, and performance calculations. Commitment periods are linked to liquidity, GP/LP terms, and fund lifecycle reporting.
