PowerShares KBW Regional Banking Portfolio 

This exchange-traded fund (ETF) primarily aims to replicate the performance of its underlying benchmark, the New Underlying Index, by investing at least 90% of its total assets in its constituent securities. This index, meticulously compiled, maintained, and calculated by an independent Index Provider, is engineered to identify and monitor companies deemed crucial for delivering key services and technological solutions to the worldwide financial sector. Its construction leverages research from Bloomberg Intelligence (BI), which is an affiliate of the Index Provider, alongside industry classifications defined by the Bloomberg Industry Classification Standard (BICS). To be included in this index, companies must satisfy several criteria: They must reside within Bloomberg's developed markets universe, which currently encompasses countries including Australia, Canada, France, Germany, Japan, the United Kingdom, and the United States, among others. Their primary business must fall into one of these categories: either classified by the Index Provider under BICS as a financial information services provider or a security & commodity exchange operator, or identified by Bloomberg Intelligence as an enterprise fintech company within its capital markets domain. They must meet the Index Provider's specific criteria for large, mid, or small market capitalization. They must maintain a free-float market capitalization of at least $500 million. And demonstrate a minimum 90-day average daily trading volume of $5 million. Each security's influence within the index is determined by its modified market capitalization. However, an individual constituent generally cannot represent more than 4.5% of the index's total weight. The index undergoes quarterly rebalancing, with adjustments made after the market closes on the third Friday of January, April, July, and October.
