The ETF Mechanism

How ETFs virtually eliminate tax drag on invested capital.

ETFs have a unique tax mechanism that allows rebalancing without triggering taxable gains. What if you could integrate that structure directly into client portfolios?

The Fund States
01A balanced fund

A $200M fund holds $100M in each of two stocks. The manager's job: keep them 50 / 50.

02One stock doubles — now lopsided

To rebalance you'd sell the winner. In a mutual fund that sale creates a gain the law forces onto every shareholder.

04Back in balance — nothing realized

Even weights again. Because no shares were sold, there's no realized gain and no forced distribution.

The Mechanism — How 02 Becomes 04

The ETF never sells — a trading firm does the work
1

An Authorized Participant (e.g. Goldman) buys $50M of Stock A on the open market and contributes it to the ETF for new ETF shares.

→ ETF now holds the Stock A it needs
2

The AP immediately redeems those shares back to the fund — requesting payment in-kind, not cash.

→ ETF selects which shares to deliver
3

The ETF hands over its most-appreciated, lowest-basis Stock B — in-kind. There is no sale.

→ No realized gain leaves the fund
IRC §852(b)(6) · The Basis Step-Up

The embedded gain is permanently extinguished.

The AP receives Stock B at today's fair market value as its cost basis — not the ETF's old low basis. The embedded gain isn't transferred to the AP. Under §852(b)(6), it is permanently extinguished.

Our Unique
ETF Application

Consolidating a client's entire equity allocation into a single ETF moves the rebalancing transactions — and the tax drag that comes with them — out of their taxable account and into a structure built to neutralize them.

No sale means no gain. Rebalancing in-kind is what lets an ETF wash gains out of the fund — year after year.
