The Antigua Blood Bank, a private charity partly supported by government grants, is located on the Caribbean island of Antigua. The Blood Bank has just finished its operations for September, which was a particularly busy month due to a powerful hurricane that hit neighboring islands causing many injuries. The hurricane largely bypassed Antigua, but residents of Antigua willingly donated their blood to help people on other islands. As a consequence, the blood bank collected and processed over 30% more blood than had been originally planned for the month. A report prepared by a government official comparing actual costs to budgeted costs for the Blood Bank appears below. (The currency on Antigua is the East Caribbean dollar.) Continued support from the government depends on the Blood Bank’s ability to demonstrate control over its costs.

He also pointed out that the additional costs had been fully covered by payments from grateful recipients on the other islands. The government official who prepared the report countered that all of the figures had been submitted by the Blood Bank to the government; he was just pointing out that actual costs were a lot higher than promised in the budget. Required: 1. Prepare a new performance report for September using the flexible budget approach. (Note: Even though some of these costs might be classified as direct costs rather than as overhead, the flexible budget approach can still be used to prepare a flexible budget performance report.) 2. Do you think any of the variances in the report you prepared should be investigated? Why?
