the Underlying Fund could also suffer losses related to its derivatives positions as a result of unanticipated market movements, which losses are potentially unlimited. BFA’s use of derivatives is not intended to predict the direction of securities prices, currency exchange rates, interest rates and other economic factors, which could cause the Fund’s derivatives positions to lose value. Derivatives may give rise to a form of leverage and may expose the Fund or the Underlying Fund to greater risk and increase its costs. Regulatory requirements may make derivatives more costly, may limit the availability of derivatives, and may delay or restrict the exercise of remedies by the Fund upon a counterparty default under derivatives held by the Fund (which could result in losses), remedies or termination rights by the Fund, and may otherwise adversely affect the value and performance of derivatives. In addition, the Fund's or Underlying Fund's use of derivatives may expose the Fund or Underlying Fund to risks related to potential operational issues, such as documentation and settlement issues, systems failures, inadequate controls and human error. Derivatives may also involve legal risks, including insufficient documentation, insufficient capacity or authority of a counterparty, and legality and enforceability of a contract.
Financials Sector Risk. The performance of companies
in the financials sector may be adversely impacted by many factors, including, among others, changes in government regulations, economic conditions, and interest rates, credit rating downgrades, adverse public perception, exposure concentration and decreased liquidity in credit markets. The impact of changes in regulation of any individual financial
company, or of the financials sector as a whole, cannot be
predicted. Cybersecurity incidents and technology malfunctions and failures have become increasingly frequent and have caused significant losses to companies in this sector, which may negatively impact the Underlying Fund.
Geographic Risk. A natural disaster could occur
in a geographic region in which the Fund or the Underlying Fund invests, which could adversely affect the
economy or the business operations of companies in the specific geographic region, causing an adverse impact on the Fund's or the Underlying Fund's investments in, or which are exposed to, the affected region.
Indexing Investment Risk. The Fund and the Underlying
Fund are not actively managed, and BFA generally does not attempt to take defensive positions under any market conditions, including declining markets.
Infectious Illness Risk. A widespread outbreak of an infectious illness, such as the COVID-19 pandemic, may result in travel restrictions, disruption of healthcare services, prolonged quarantines, cancellations, supply chain disruptions, business closures, lower consumer demand, layoffs, ratings downgrades, defaults and other significant economic, social and political impacts. Markets may experience temporary closures, extreme volatility, severe losses, reduced liquidity and increased trading costs. Such events may adversely affect the Fund and its investments and may impact the Fund’s ability to purchase or sell securities or cause elevated tracking error and increased premiums or discounts to the Fund's NAV. Despite the development of vaccines, the duration of the COVID-19
