If I can reciprocate in any way, please do not hesitate to contact me.

Thank you for sending me the personnel file on John Doe. He is due for a review this month, and I have not worked closely enough with John to make any decisions without the information in his file. Please let me know if there is anything I might do to make your job easier as you face personnel reviews or other hectic times.
