Q

Price Elasticity

A

% change in quantity demanded / % change in price; note that the absolute value of the calcuation is considered when elasticity problems are posed on the CPA exam, as it is assured that price elasticity is negative for a normal demand curve when the price elasticity of demand is less than 1.0 it is considered inelastic.

25
Spending variance or labor rate variance

27

28

Ks = (D1/P0) + expected growth rate
29
Cost of new common stock
Kx = [D1 / (P0 - F)] + expected growth; F= floating cost per share
30
Economic value added
Step 1: calculate required rate of return; Step 2: anything above rate of return is economic value added
31
Average collection period
1. calc receivables turnover = sales / average receivables; 365 days / receivables turnover
32
Gross domestic product (expenditures approach)
government purchases + gross domestic investments + personal consumption +/- net exports (exports - imports)
33
Gross domestic product (income approach)
Income of proprietors + corporate profits + net interest + rental income + adj for net foreign inc + indirect business taxes + employee wages + depr.
34
Capital budgeting
cash inflos b/4 tax - depr on investment = increase in taxable income - tax = increase in acctg net income cash inflows b/4 tax - tax = after tax net cash inflow; or increase in acctg net income + depr on investment = after-tax net cash inflows
35
Cost of bond issue
interest rate x (1-effective rate)
36
Traditional costing (application of overhead)
Step 1: calculate overhead rate = budgeted overhead cost / estimated cost driver (DL $, DLH, MH); step 2: applied overhead = actual cost driver x overhead rate (from step 1)
37
Prime cost
direct labor + direct marketing
38
Conversion cost
direct labor + manufacturing overhead
39
Cost accounting systems are designed to meet the goal of measuring cost objectives or objectives. The most frequent objectives include
Product costing (inventory and cost of goods manufactured and sold); Income determination (profitability); Efficiency measurements (comparisons to standards)
40
Absorption approach - Product
COGS = DM + DL + O/H (fixed & variable)
41
Contribution approach
all fixed factory overhead is treated as a period cost and is expensed in the period incurred. Inventory values include only the variable manufacturing costs, so cost of goods sold includes only variable manufacturing costs.
42
Variable (Direct) Costing
Direct material + director labor + variable manufacturing overhead; fixed manufacturing overhead is a period costs
43
Cost accumulation systems
are used to assign costs to products. If the cost object is a custom order, job costing is used. IF the cost oject is a mass-produced homogeneous product (e.g. steel), process costing is used.
44
Job-order costing
Is the method of product costing that identifies the job (or individual units or batches) as the cost objective and is used when there are relatively few units produced and when each unit is unique or easily identifiable. Cost is allocated to a specific job as it moves through the manufacturing process.
45
Process costing
Process costing is a method of product costing that averages costs and applies the to a large number of homogeneous items.
46
Inventory: raw materials
Beginning inventory of raw materials + purchases of raw materials - raw materials used * = ending inventory of raw materials
47
Inventory: work in process
Beginning inventory of work in process + *raw materials used plus direct labor and overhead used - inventory transferred to finished goods* = ending inventory of work in process
48
Inventory: finished goods
Beginning inventory of finished goods + *inventory transferred from work in process - cost of goods sold = ending inventory of finished goods
49
DM price variance
Actual quantity pruchased x (actual price - standard price)
50
DM quantity usage variance
Standard price x (actual quantity used - standard quantity allowed)
51
DL rate variance
Actual hours worked x (actual rate - standard rate)
52
DL efficiency variance
Standard rate x (actual hours worked - standard hours allowed)
53
Four types of variances for raw materials and direct labor
Price variance (for DM; Usage (quantity) variance (for DM); Rate variance (for DL); Efficiency variance (for DL) memorize DADS with PURE DA Difference x Actual; DS Difference x Standard; DA Difference x Actual; DS Difference x Standard
54
VOH rate (spending) variance
Actual hours x (Actual rate - Standard rate)
55
VOH efficiency variance
Standard rate x (actual hours - standard hours allowed for actual production volume)
56
FOH budget (spending) variance
Actual fixed overhead - budgeted fixed overhead
57
FOH volume variance
Budgeted fixed overhead - Standard fixed overhead cost allocated to production* ; (*based on actual production x standard rate)
58
Sales price variance
[(actual sp/unit) - budgeted sp/unit)] x actual sold units
59
Sales volume variance
[(actual sold units - budgeted sales unit)] x standard contribution margin per unit
60
Discounted cash flow is the basis for net present value methods:
Step 1: calculate after-tax cash flows = annual net cash flow x (1-tax rate); Step 2: add depreciation benefit = depreciation x tax ate; Step 3: multiply results by appropriate present value of an annuity; Step 4: subtract initial cash outflow; Result: net present value
61
Profitability Index
Present value of net future cash inflow / present value of net initial investment
62
Present Value
FV / (1+r)^n
63
DOL
% change in EBIT / % change in sales
64
% change in operating income
% change sales x DOL
65
DFL
Asset/Equity
66
DTL
DOL x DFL or % change EPS / % change in sales
67
Cost of debt (after tax)
Interest rate x (1-tax rate)
68
Debt
carries the lowest cost of capital and is tax deductible; the higher the tax rate, the more incentive exists to use debt financing.
69
Cost of preferred stock
Preferred stock dividends / net proceeds of preferred stock or preferred stock dividends / selling price - flotation cost
70
ROA
Net income / Average total assets
71
ROI
NI / (D+E)
72
ROE
Net income / total equity
73
DuPont ROE
Net profit margin x asset turnover x financial leverage or (net income/sales) x (sales/average total assets) x (average total assets/equity) or net income/total equity
74
Extended DuPont ROE
Tax burden x Interest burden x Operating income margin x asset turnover x financial leverage; (net income/pretax income) - (pretax income/EBIT) x (EBIT/sales) x (sales/average total assets) x (average total assets/equity) or NI/sales x sales/average total assets x average total assets/equity
75
ROE (DuPont and extended DuPont)
Produces the same result however, management can get a better understanding of what factors are driving ROE and how those factors compare relative to competing companies and to the industry overall.
76
Economic value added
NOPAT - WACC
77
Debt to total capital ratio
total debt/total capital; the lower the ratio, the greater the ability of firm to pay debt. The debt-to total capital ratio is alternatively expressed as the debt-to asset ratio.
78
Debt to total asset ratio
total debt/total assets; indicates long-term debt -paying ability. The lower the ratio, the better protection afforded to creditos.
79
Debt-to-equity ratio

80
Times interest earned

81
Quick (Acid Test) Ratio
(cash + marketable securities + receivables)/current liabilities
82
Drafts
The use of drafts or checks serves to delay cash disbursements. Using drafts instead of checks increases the payable float.
83
