Offering a small premium on government securities, such bonds would likely attract long-term investors like pension funds, which otherwise face zero or even negative real returns. For example, with a fiscal outlay of €21 billion ($23.3 billion), the European Investment Bank is set to finance investments worth at least €315 billion by 2017.
相对政府债券，这类债券提供较小的溢价，有望吸引退休基金等长期投资者，否则这类投资者将面临零甚至负实际回报。比如，在财政支出只有210亿欧元的情况下，到2017年，欧洲投资银行需要为至少3,150亿欧元的投资项目融资。
