Build America Bonds (a variation on the taxable bond) were introduced as part of the American Recovery and Reinvestment Act (ARRA) of 2009. According to the White House,[xxviii] over $70 billion in Build America Bonds have been issued in 47 states since April 2009 to fund a wide array of critical infrastructure projects. Build America Bonds provide a 35% reimbursement to states. The Build America Bond Program is near the end of its authorized life, but there's a possibility it may be renewed giving states another avenue to finance public infrastructure at especially attractive rates of return.
