Why do International Equity SMA Portfolios use ADR only?

I work on fund and don’t really understand the logic behind only using ADRs in SMA portfolios. Does it just come down to commissions?

Does it eliminate foreign exchange related headaches?

Well, the execution is typically easier but ADRs have exposure to the underlying’s currency and carry a custody fee you don’t have with ORDs.

Seems like laziness, or people want international exposure but don’t want money sitting in foreign currencies.

I agree that there doesn’t seem to be a lot of logic there. Most likely, you lose diversification by going ADR-only. Though perhaps they’ve done some risk/reward or liquidity analysis and concluded that going beyond ADRs provide little realizable value for smaller SMAs.
