Operating expenses stand at 0.03% per annum, among the lowest in the fixed-income ETF universe. The fund’s annual distribution yield is 3.88%, and its five-year beta versus the S&P 500 is 0.27, reflecting low correlation to equities. With assets under management totalling $137 billion, the ETF remains one of the largest vehicles for investment-grade bond exposure in the U.S. market.
