Insurance Coverage Q&A: Business Income Loss Following Computer Crash

I have a coverage questions in regards to BI and Extra Expenses. I insure a manufacturer that had their computer system crash causing them to loose very vital information needed to keep the business running. The insured had their existing employees work to rebuild all the programs and input all the necessary information in order to get back up in running. They did this instead of hiring an outside 3rd party since they believed it would be much more cost effective and efficient. With this being said these employees had to take time away from their typical daily job tasks to get the company back up in running. My insured is looking to be reimbursed for this cost. They had to push out sales and shipments since they had to allocate efforts to rebuild their software. My understanding is that this extra expenses or incurred cost should be covered. Am I correct?
