Because of this safety feature, tempered glass is used in the side and rear windows of automobiles made in the United States, as well as in the windshields of some foreign- made cars. Flotation is a method used by scientists to determine the ________________ of a particle of glass.
Coupon tells us the rate of returns(%) for the bonds when it was first issued based on issue price. Yield tells us the rate of returns(%) for the bond based on current price. Assuming a bond was issued at $1000, promising to pay $50 yearly, it has a coupon rate of 5% & yield of 5%. However, if due to unforseen circumstances the bond price drops to $500, it still has a coupon rate of 5% but the yield is currently 10%. Coupon (%) = Returns / Issue Price * 100.
Yield can be different than coupon rates based on the principal price of the bond. If the price is par at time of purchase and you receive par at maturity, then the yield and coupon will be the same. For instance, say a bond at issuance is priced at 100 with 10% coupons. You pay 100 initially and receive 10% coupons over the life of the bond. At maturity, you receive 100.
