A share class is a version of a fund’s shares carrying its own fee and distribution terms — same portfolio, different cost structure depending on how the shares are sold. In NAV REITs, perpetual BDCs, and interval funds, the multi-class system (commonly Classes S, D, I, and T) is how one product serves brokerage, advisory, and institutional channels at once.
How the class system works
Every class owns the identical portfolio; the differences are entirely in distribution economics. The recurring architecture in perpetual products:
- Class S — the brokerage-channel class: an upfront sales load (often up to ~3.5%) plus the largest ongoing shareholder servicing/distribution fee (commonly ~0.85% annually), compensating broker-dealer selling firms.
- Class T — a similar transactional class with a differently split load and trail, used by some sponsors alongside or instead of S.
- Class D — the fee-based/discount class: little or no upfront load and a smaller trail (~0.25%), typically for advisory programs and certain platforms.
- Class I — institutional: no load, no servicing fee, the lowest expense ratio — for institutions, RIAs, fee-based wrap programs, and large tickets.
Trailing fees on S/T/D classes are usually capped: once cumulative underwriting compensation on a share hits regulatory limits (FINRA Rule 2310's framework), the trail stops or shares convert toward the cheaper class. When a REIT is organized as a trust, the instruments are formally common shares of beneficial interest — same idea, trust vocabulary.
Why it matters: class selection is a pure cost decision on an identical portfolio, which is exactly why regulators watch it. An investor eligible for Class I who’s placed in Class S pays a load plus ~0.60% more per year for the same fund — compounding drag with no offsetting benefit — and share-class selection has been a recurring Reg BI and SEC enforcement theme in mutual funds and alternatives alike. Class also quietly shapes reported performance: sponsor materials frequently lead with Class I returns, while a client in Class S experiences load-and-trail-reduced results. Reading the fee table by class, and confirming eligibility for the cheapest available one, is among the highest-value five minutes in semi-liquid product diligence.
FAQ
What is a share class in simple terms?
Different price tags on the same fund: each class holds the identical portfolio but charges different loads and ongoing fees depending on the sales channel.
What's the difference between Class S and Class I shares?
Class S carries an upfront load and the largest ongoing servicing fee (brokerage channel); Class I has neither (institutional/advisory channel). Same investments, materially different net returns over time.
Why do funds have multiple share classes?
To distribute one product through channels with different compensation models — commissions for broker-sold shares, clean pricing for fee-based and institutional buyers.
