INTEGRATIVE
EXERCISE (CHAPTERS 5-10)
The
Two Cost Systems
Sacred
Heart Hospital (SHH) faces skyrocketing nursing costs, all
which relate to its two biggest nursing service lines – the Emergency Room (ER)
and the Operating Room (OR). SHH’s current cost system assigns total nursing
costs to ER and OR based on the number of patients serviced by each line. Total
hospital annual nursing costs for these two lines are expected to equal
$300,000. The table below shows expected patient volume for both lines.

3. Using
the results from Requirement 2, calculate the cost per OR nursing hour under
the current cost system.
Cost per OR nursing hour : $150,000 : $30

After discussion with several
experienced nurses, Jack Bauer (SHH’s accountant) decided that assigning
nursing costs to the two service lines based on number of time that nurses must
check patients’ vital signs might more closely match the underlying use of
costly hospital resources. Therefore, for comparative purposes, Jack decided to
develop a second cost system on his computer that assigns total nursing costs
to the ER and OR based on the number of times nurses check patients’ vital
signs. This system is referred to as the “vital-signs costing system.” The
earlier table also shows data for vital signs checks for lines.
4. Using
the vital-sign costing system, calculate the hospital-wide rate based on the
number of vital signs checks.
The hospital-wide rate : $300,000 : $50

5. Calculate
the amount of nursing costs the vital-signs costing system assigns to the ER
and to the OR.

Budgeting
and Variance Analysis
In an effort to better plan for and
control OR costs, SHH management asked Jack to calculate the flexible budget
variance (i.e., flexible budget costs-actual costs) for OR nursing costs,
including the price variance and efficiency variance that make up the flexible
budget variance for OR nursing costs. Given that Jack is interested in
comparing the reported costs of both systems, he decided to prepare the
requested OR variance analysis for both the current cost system and the vital
signs costing system. In addition, Jack chose to use each cost system’s
estimate of the cost per OR nursing hour as the standard cost per OR nursing
hour. Jack collected the following additional information for use in preparing
the flexible budget variance for both systems:
Actual number of surgeries performed =
950
Standard number of nursing hours allowed
for each OR surgery = 5
Actual number of OR nursing hours used =
5,000
Actual OR nursing costs = $190,000
7. For
the OR service line, use the information above and the cost per OR nursing hour
under the current cost system to calculate the
a.
Flexible budget variance. (Hint: Use your answer to Requirement 3
as the standard cost per OR nursing hour for the current cost system).

= $190,000/5,000 = $38

Discussion
of Reported Costs and Variances from the Two Systems
9. Consider
SHH’s need to control its skyrocketing costs, Jack’s discussion with
experienced nurses regarding their use hospital resources, and the reported
costs that you calculated from each cost system. Based on the consideration,
which cost system (current or vital signs) should Jack choose? Briefly explain
the reasoning behind your choice.
Sistem Cost yang harus dipilih oleh
Jack adalah vital sign karena lebih menguntungkan dan lebih menggamarkan dengan
keadaan yang sebenarnya.
10. What
does each of the calculated variances suggest to Jack regarding actions that
should or should not take with respect to investigating and improving each
variance? Also, briefly explain why the variances differ between the two cost
systems.
Varian adalah perbedaan antara
standar harga dan kuantitas dengan harga dan kuantitas yang sebenarnya terjadi.
Jika varian nya semakin besar maka Jack harus segera melakukan investigasi
penyebabnya untuk dapat mengontrol biaya. 2 cost sistem memberikan varian yang
berbeda karena standar cost unit yang digunakan juga berbeda.
Problem 11-57
Understanding Relationships, Incomplete Data, Overhead Analysis
Lynwood Company produces surge
protectors. To help control costs, Lynwood employs a standard costing system
uses a flexible budget to predict overhead costs at various levels of activity.
For the most recent year, Lynwood used a standard overhead rate of $18 per
direct labor hour. The rate was computed using practical activity. Budgeted
overhead costs are $396,000 for 18,000 direct labor hours and $540,000 for
30,000 direct labor hours. During the past year, Lynwood generated the
following data: (a) Actual production: 100,000 units; (b) Fixed overhead volume
variance: $20,000 U; (c) Variable overhead efficiency variance: $18,000 F; (d)
Actual fixed overhead costs: $200,000; and (e) Actual variable overhead costs:
$310,000.
Required:
1. Calculate
the fixed overhead rate
Fixed overhead rate = $200,000 = $2
100,000
2. Determine
the fixed overhead spending variance
Fixed overhead spending variance = Actual Fixed Overhead – Budgeted
Fixed Overhead
=
$200,000 - $196,000
=
$4000 U
3. Determine
the variable overhead spending variance
Variable overhead spending variance
= Actual variable overhead – (AH x
SVOR)
=
$310,000 – $302,004
=
$7,996 U
4. Determine
the standard hours allowed per unit of product
Standard hours allowed per unit
product = 0.2667 hour per unit
