9. The following formula may be used to determine total budgeted costs at any level of activity:
Total budgeted costs = Fixed costs + (Total variable cost per unit X Activity level)
10. Total budgeted costs at each level of activity can be shown graphically.
a. In a graph, the activity index is shown on the horizontal axis and costs are shown on the
vertical axis.
b. The total budgeted costs for each level of activity are then identified from the total budgeted
cost line.
Responsibility Accounting and Responsibility Centers
12. (L.O. 3) Responsibility accounting involves accumulating and reporting costs (and revenues,
where relevant) on the basis of the manager who has the authority to make the day–to-day
decisions about the items. A manager’s performance is evaluated on matters directly under that
manager’s control.
13. Responsibility accounting can be used at every level of management in which the following
conditions exist:
a. Costs and revenues can be directly associated with the specific level of management
responsibility.
14. Responsibility accounting is especially valuable in a decentralized company. Decentralization
means that the control of operations is delegated to many managers throughout the organization.
A segment is an identified area of responsibility in decentralized operations.
15. Responsibility accounting is an essential part of any effective system of budgetary control. It
differs from budgeting in two respects:
a. A distinction is made between controllable and noncontrollable items.
b. Performance reports either emphasize or include only items controllable by the individual
manager.
16. A cost is considered controllable at a given level of managerial responsibility if that manager has
the power to incur it within a given period of time. Costs incurred indirectly and allocated to a
responsibility level are considered to be noncontrollable at that level.
