And that's not to say that there are not costs involved, environmental risks involved.

这并不是说不涉及成本， 涉及环境风险。

Few borrowers want to risk huge prepayment costs if their circumstances change and markets have moved in the wrong direction.

如果情况发生变化并且市场朝着错误的方向发展，很少有借款人愿意承担巨额提前还款成本的风险。

Thus the long-period supply price is equal to the sum of the prime cost, the supplementary cost, the risk cost and the interest cost, into which several components it can be analysed.

因此，长期供应价格等于主要成本、补充成本、风险成本和利息成本之和， 可以分解为几个组成部分。
