Frequently Asked Questions
Can I buy KB Financial Group from a US brokerage account?
Yes. KB is listed on the NYSE as a sponsored ADR and trades like any US-listed stock at any major US brokerage (Schwab, Fidelity, Interactive Brokers, etc.).
How are KB dividends taxed?
Under the US-Korea tax treaty, Korean withholding tax of 15% is deducted first. US residents can claim a foreign tax credit (Form 1116) to offset this against US tax owed. When KB Financial Group pays dividends, ADR holders receive the equivalent in USD (after a small depositary fee).
Why does KB sometimes trade at a different price than the Korean shares?
In theory, the ADR price should equal (Korean share price ÷ exchange rate) × ADR ratio. In practice, premiums or discounts arise from (1) time-zone gaps — Korea's market closes before US trading begins, (2) USD/KRW exchange rate moves, (3) limited ADR liquidity, and (4) arbitrage costs. Even sponsored NYSE ADRs show minute-by-minute deviations.
What does an ADR ratio of 1:1 mean?
It means 1 ADR represents 1 ordinary share of KB Financial Group. With a 1:1 ratio, you only need to apply the USD/KRW exchange rate to compare prices directly.
