Request comments from my boss

As my boss promised to provide his comments for my report last week, but no response was found from him until now. I would like to ask him when will be available for the comments on my report. How can I write to him politely?

Please help to comment the following sentences whether are polite or not.

1. Please be reminded that the comments on my report are still outstanding and please forward it to me as soon as possible.

1. As the comments on my report are still outstanding. I hope I’m not intruding, but could you tell me about your comments by this week?
