Are all PRIIPs the same?

No. PRIIPs fall into four categories depending on NAV frequency, payoff structure and availability of (sufficient) historical data. Generally we could state that UCITS are always Category II, closed-ended privat market funds (Private Equity/Real Estate) are Category I, and Structured Products fall into Category III or IV. Semi-liquids (evergreens) are often Category I because of the lack of an appropriate benchmark or proxy.
