This ETN was delisted after the market close on April 12, 2018, and now trades over-the-counter on the pink sheets. As a result, shareholders should anticipate ultra-wide spreads, minimal trading volumes, and prices well above or below NAVs. GBB delivers the returns of the British pound/US dollar exchange rate, along with the British overnight lending rate. The concept is simple: Provide straightforward access to the same pattern of returns (before expenses) that an investor would receive if he were to purchase the British pound with US dollars and store the currency at a bank in the UK. GBB has succeeded in that respect, but the note suffers from low assets and little-to-no trading volume, so tread carefully. In fact, GBB is at high risk of getting shut down. Structured as an ETN, GBB comes with credit risk of the issuing bank, Barclays. On the tax front, gains are all taxed as ordinary income.
