That 7.375% on the Coca-cola bond looks like the coupon (approximate yield) from its initial issue, which appears to be in 1993. ("Ticker: KO 7.375 07/29/93") The yield-to-maturity (yield calculated from current market price) is likely to be lower. Coca-Cola is A-rated[1], and Schwab is showing A-rated corporate bonds as yielding 5% (3-month) to 6.4% (30 years)
