Exhaustive Cost Accounting & Decision Analytics Study Guide

Financial Accounting

Focuses on preparing historical, quantitative, and verifiable financial statements for external users under GAAP guidelines.

Management Accounting

Provides real-time, forward-looking financial and nonfinancial information to internal managers for planning, decision-making, and operational control.

Cost Accounting

Measures and analyzes product or service costs to support both financial accounting (inventory valuation) and management accounting (pricing and control).

Cost Leadership Strategy

A strategy aimed at gaining competitive advantage by becoming the lowest-cost producer in the industry.

Differentiation Strategy

A strategy aimed at offering unique, high-quality features that command premium pricing from customers.

Value Chain

The sequential set of business functions (R&D, Design, Supply, Production, Marketing, Distribution, Customer Service) through which an enterprise creates value.

Direct Cost

An expense that can be conveniently and economically traced to a specific cost object.

Indirect Cost

An expense that cannot be conveniently or economically traced to a specific cost object and must be allocated.

Relevant Range

The operational band of activity volume within which assumed cost behavior patterns remain linear and valid.

Variable Cost

A cost that changes in total direct proportion to changes in activity volume, but remains constant on a per-unit basis within the relevant range.

Fixed Cost

A cost that remains constant in total regardless of activity changes within the relevant range, but varies inversely on a per-unit basis.

Prime Costs

The sum of direct materials and direct labor costs ($\text{DM} + \text{DL}$).

Conversion Costs

The sum of direct labor and manufacturing overhead costs ($\text{DL} + \text{OH}$).

High-Low Method

A technique to separate mixed costs into fixed and variable components using the highest and lowest representative activity levels.

Sarbanes-Oxley Act (SOX)

Legislation holding CEOs and CFOs personally and criminally liable for the accuracy and completeness of corporate financial reports.

Sarbanes-Oxley Act (SOX)

Legislation holding CEOs and CFOs personally and criminally liable for the accuracy and completeness of corporate financial reports.

Sunk Cost

A cost incurred in the past that cannot be changed by any future action and is always irrelevant in decision-making.

Opportunity Cost

The benefit foregone when selecting one course of action over another alternative.

Incremental Cost

The difference in total cost between two decision alternatives.

Outsourcing Decision

An evaluation comparing internal production and opportunity costs against external purchase costs to determine whether to manufacture an item in-house or acquire it externally.

Scarce Resource Optimization Rule

The principle that products should be prioritized based on the highest contribution margin per unit of scarce resource to maximize total short-run profitability.

Special Order Decision

A decision process evaluating a one-time or non-routine customer request where the minimum acceptable price must cover variable production, variable selling, and any incremental fixed costs.

Segment Margin

The contribution margin of a specific business segment minus its avoidable direct fixed costs, used to evaluate whether to retain or drop the segment.

Linear Cost Estimating Equation

The mathematical formula $Y = a + bX$, where $Y$ is total cost, $a$ is total fixed cost, $b$ is variable cost per unit of activity, and $X$ is the activity level.

Mixed Cost

A cost containing both fixed and variable components, where total cost changes with activity volume but not in direct proportion.

Step Cost

A cost that remains constant over a narrow band of activity but shifts upward or downward in total by a discrete amount once activity crosses a specific threshold.

Coefficient of Determination ($R^2$)

A statistical metric ranging from $0$ to $1$ that measures the proportion of total variation in a dependent cost variable explained by an independent activity driver.

Incremental Unit Time Learning Curve Model

A cost estimation model where the labor time required to produce the single last unit is reduced by a constant percentage rate every time cumulative production quantity doubles.

Cumulative Average Time Learning Curve Model

A cost estimation model where the cumulative average labor time required per unit across all produced units is reduced by a constant percentage rate every time cumulative production quantity doubles.

Cost Object

Any item, unit, project, customer, or organizational segment for which management desires a separate measurement of costs.

Unexpired Cost

An asset balance on the balance sheet representing economic resources that have not yet been consumed to generate revenue.

Cost of Goods Manufactured (CGM)

The total product cost accumulated for units completed and transferred out of work-in-process inventory into finished goods inventory during an accounting period.

Overhead Allocation

The systematic assignment of indirect manufacturing costs to cost objects using a representative activity driver.

Four Types of Data Analytics

The framework consisting of Descriptive (what happened), Diagnostic (why it happened), Predictive (what will happen), and Prescriptive (what actions to take) analytics.

IMA Four Ethical Standards

The core professional standards established by the Institute of Management Accountants: Competence, Confidentiality, Integrity, and Credibility.
