Schiffers controller uses the following rule of thumb: Investigate all variances equal to or greater than $30,000, which is 6 percent of standard cost.

Required:

Which variances would have been investigated during the year? (Indicate month and type of variance.)

What characteristics of the variance pattern shown in the report should draw the controllers attention, regardless of the usual investigation rule?

Which of the following is the best reason to also follow up on favorable variances?

Which variances would have been investigated during the year? (Indicate month and type of variance.) Note: Indicate the effect of each variance by selecting "Favorable" or "Unfavorable". Select "None" and enter "0" for no effect (i.e., zero variance).) Round "Percentage of Standard cost" to 2 decimal places. What characteristics of the variance pattern shown in the report should draw the controller's attention, regardless of the usual investigation rule? Note: Select "Yes" if the characteristics of the variance pattern draws the controller's attention, and "No" if it does not.
