海外投資- ishare AOA 成本疑問 ishare AOA 成本疑問

因為最近開始學習指數投資
打算利用複委託AOA
搜尋了一下建議和市場先生等 查到的費用都是0.25%
但上去iShare 官網查 卻0.15%??

Fees
as of current prospectus
Management Fee 0.15%
Acquired Fund Fees and Expenses 0.05%
Foreign Taxes and Other Expenses 0.00%
Expense Ratio 0.20%
Fee Waivers 0.05%
Net Expense Ratio 0.15%
請問一下 是有另外的扣血嗎?
謝謝
