AGG Liquidity, Domicile & Tax Treatment

Liquidity: Average daily volume is 9.5M/day. Higher volume and a larger fund generally mean lower round-trip trading costs. AUM of $136B provides ample scale, supporting tight spreads and issuer commitment to keep the fund open.

Domicile & tax treatment: AGG is a US-domiciled, SEC-registered ('40 Act) exchange-traded fund. Dividends and capital gains distributions are reported to US investors on Form 1099-DIV, and the fund is not subject to the PFIC reporting or UCITS-specific rules that apply to Irish- or Luxembourg-domiciled funds. Non-US investors should note that US-domiciled ETFs are generally subject to 30% US withholding tax on dividends (unless reduced by treaty) and to US estate tax exposure on the position — Irish-domiciled UCITS ETFs tracking the same index often avoid both, which is why non-US residents frequently prefer the UCITS equivalent where one exists. This is general information, not tax advice — consult a tax professional for your situation.
