until the date hereof and thereafter at the judgment rate until payment这句话的翻译

同上，这句话经常在香港的一些判决中出现，比如the 1st and 2nd Defendants do pay the Plaintiff the sum of USD1,391,902.24 or the Hong Kong dollar equivalent at the time of payment with interest thereon at the rate of 4% per month from 18th March 2008 until the date hereof and thereafter at the judgment rate until payment;前面的我还能看懂，后面这一句两个UNTIL把我搞糊涂了，而且 at the judgment rate 如何理解？是不是“判决中确定的比率”？hereof and thereafter 是什么意思？多谢达人指教？PS 拿翻译器翻译的不要来了，再次提示

不知道

at the judgment rate 判决率 hereof and thereafter 在此期间和以后
