The iShares Global Healthcare ETF seeks to track the investment results of an index composed of global equities in the healthcare sector. The Fund seeks investment results that correspond generally to the price and yield performance, before fees and expenses, of the SP Global Healthcare Sector Index (the Underlying Index). The Underlying Index measures the performance of companies that SP deems to be a part of the healthcare sector of the economy and that SP believes are important to global markets. It is a subset of the SP Global Index. Component companies include health care providers, biotechnology companies and manufacturers of medical supplies, advanced medical devices and pharmaceuticals. The Fund generally invests at least 90% of its assets in securities of the Underlying Index and in depositary receipts representing securities of the Underlying Index.
