would have

Are these sentences OK?

I told John that I did not review the December 2015 operation report as I assumed Robert who had prepared the report would have reviewed it before he left for his holiday.

There's only one sentence. It's missing a couple of commas to set off a parenthetical remark.

Even with the commas, it could be improved by dividing it into two sentences.

 

[Tarheel]

Actually, you need three commas -- after "report", after Robert", and after "report".

 

[Matthew Wai]

Is it correct to replace 'did' with 'would'?

 

[GoesStation]

With "did", it means that you simply didn't review the report. With "would" it means you refused to read it.
