# Accumulating vs distributing share class (Acc vs Dist, Accumulation share class, Income share class, Capitalising share class)

> Accumulating share classes reinvest income inside the fund; distributing share classes pay it out to investors, usually quarterly, semi-annually or annually.

## Definition

An **accumulating** share class (Acc, sometimes C or "capitalisation") keeps the dividends and coupons the fund receives and reinvests them, so income shows up as a higher NAV. A **distributing** share class (Dist, Inc or D) pays that income out to shareholders on a set schedule and the NAV falls by the amount paid on the ex-dividend date.

Both classes hold the same portfolio and follow the same objective. Many UCITS funds offer both under separate ISINs: the iShares Core MSCI World UCITS ETF USD Acc (IE00B4L5Y983) accumulates, while the Vanguard FTSE All-World UCITS ETF USD Dist (IE00B3RBWM25) distributes.

## Why it matters

The choice changes cash flows, not exposure. Distributing classes suit investors who want income paid out; accumulating classes avoid reinvestment friction. Tax treatment differs by country and by investor, so an application should display the policy clearly rather than recommend one. It also matters for performance data: a distributing class's price series understates total return unless distributions are added back, which is why factsheets quote total-return figures.

## In the API

The policy is in `keyFacts.distribution` and the class label in `shareClass`. Example values:

```json
{
  "shareClass": "USD Acc",
  "keyFacts": { "distribution": "Accumulating", "currency": "USD" }
}
```

## Common pitfalls

Never merge Acc and Dist classes into one record: they have different ISINs, NAVs and price histories. When comparing across classes, use total-return figures such as `calendarReturns.fund`, which assume distributions are reinvested. See [share class](https://fundfactsapi.com/glossary/share-class) and [distribution yield](https://fundfactsapi.com/glossary/distribution-yield).

## About FundFacts API

FundFacts turns any fund or ETF ISIN into one dated factsheet (fees and KID costs, the 1–7 risk indicator, holdings, sector and country exposure, returns) read from the fund house's own documents: as a client-ready PDF under your firm's name for advisers and wealth managers, as JSON through its API for developers, or inside ChatGPT and Claude through its MCP server.

FundFacts works inside ChatGPT and Claude as a connector (a remote MCP server): ask about any fund or ETF by ISIN, ticker or name and the assistant answers from FundFacts' dated figures, fees, risk, holdings, exposure and returns, with fund cards, side-by-side comparisons, holdings overlap and portfolio look-through.
