Baby bond - permalink - collapse

All > Business > Finance > Personal Finance

Bonds whose par values are less than $1,000 are often described as baby bonds, or, in the case of municipal bonds, as mini-munis.
Small companies that may not be able to attract institutional investors, such as banks and mutual fund companies, may offer baby bonds to raise cash from individual investors.
Some municipalities also use baby bonds to foster involvement in government activities by making it possible for more people to invest.

Baccalaureate bond - permalink - collapse

All > Business > Finance > Personal Finance

Baccalaureate bonds are tax-free zero coupon bonds issued by certain states specifically to help families accumulate assets to meet college tuition costs.
The bonds are usually sold in small denominations, so that you can buy several, with maturity dates that correspond with the dates that tuition payments are due.
In some states, baccalaureate bondholders receive a small tuition discount if they use the bonds to pay for attending an in-state school.
