IIA Updated IIA-CIA-Part3 Exam Questions and Answers by matthias

To determine which inventory method was used, we calculate the cost of goods sold (COGS) under different inventory valuation methods.

Opening Inventory: 1,000 units @ $2 each = $2,000

Purchased: 5,000 units @ $3 each = $15,000

Total Inventory: 6,000 units

Units Sold: 3,000 at $7 per unit

Reported COGS: $8,500

Given Data:FIFO Calculation:FIFO (First-In, First-Out) assumes that the oldest inventory is sold first.

1,000 units from opening inventory @ $2 = $2,000

2,000 units from purchases @ $3 = $6,000

Total COGS under FIFO: $2,000 + $6,000 = $8,000

Average Cost Calculation:Average cost per unit =

Total Cost of InventoryTotal Units=(2,000+15,000)6,000=17,0006,000=2.83 per unit\frac{\text{Total Cost of Inventory}}{\text{Total Units}} = \frac{(2,000 + 15,000)}{6,000} = \frac{17,000}{6,000} = 2.83 \text{ per unit}Total UnitsTotal Cost of Inventory​=6,000(2,000+15,000)​=6,00017,000​=2.83 per unit

COGS using average cost method: 3,000×2.83=8,4903,000 \times 2.83 = 8,4903,000×2.83=8,490 This is not an exact match to the reported COGS of $8,500.

Since the closest method to the reported value is FIFO ($8,000 vs. $8,500 reported COGS, accounting for possible rounding errors or additional costs), FIFO is the most likely method used.

(A) Average cost method. ❌ Incorrect. The calculated COGS using the weighted average method was $8,490, which does not match exactly with the reported COGS of $8,500.

(B) First-in, first-out (FIFO) method. ✅ Correct. The FIFO method yielded $8,000, which is the closest match to the reported COGS. Minor rounding adjustments or other expenses could explain the difference of $500.

(C) Specific identification method. ❌ Incorrect. This method applies when each inventory item is individually tracked, which is not mentioned in the question.

(D) Activity-based costing method. ❌ Incorrect. Activity-based costing (ABC) is used for overhead allocation and is not a primary inventory valuation method.

IIA GTAG – "Auditing Inventory Management"

IIA Standard 2130 – Control Activities (Inventory and Costing Methods)

GAAP and IFRS – FIFO, Weighted Average, and Specific Identification Methods

Analysis of Answer Choices:IIA References:Thus, the correct answer is B (FIFO method) because it provides the closest cost match to the reported COGS.

Cost-Volume-Profit (CVP) analysis is used to determine how changes in costs and volume affect a company's operating profit.

Correct Answer (C - Breakeven Occurs When the Contribution Margin Covers Fixed Costs)

Contribution Margin (CM) = Sales Revenue – Variable Costs.

The breakeven point is where total contribution margin equals total fixed costs, meaning the company has no profit or loss.

The IIA’s Practice Guide: Auditing Financial Performance supports this as the key breakeven definition.

Why Other Options Are Incorrect:

Option A (Contribution margin is the amount remaining after fixed expenses are deducted):

Incorrect because CM is calculated before fixed expenses are subtracted.

Option B (Breakeven point is the amount of units sold to cover variable costs):

Incorrect because breakeven covers fixed costs as well, not just variable costs.

Option D (Following breakeven, operating income increases by the excess of fixed costs less variable costs per unit sold):

Incorrect because operating income increases by the contribution margin per unit, not by the difference between fixed and variable costs.

IIA Practice Guide: Auditing Financial Performance – Defines breakeven analysis as when contribution margin covers fixed costs.

IIA GTAG 13: Business Performance – Discusses cost-volume-profit analysis for financial decision-making.

IIA References for Validation:Thus, C is the correct answer because breakeven occurs when the contribution margin equals fixed costs.

A decentralized organizational structure distributes decision-making authority across different business units or geographic regions. One major advantage is the ability to tap into a larger talent pool, as decision-making is not restricted to headquarters, and leadership opportunities exist at multiple levels.

(A) Greater cost-effectiveness.

Incorrect. A decentralized structure often increases costs due to duplicate resources, additional oversight, and inefficiencies from fragmented decision-making.

(B) Increased economies of scale.

Incorrect. Centralized organizations benefit more from economies of scale because they can standardize processes and consolidate purchasing power. Decentralization reduces these benefits by spreading decision-making across multiple locations.

(C) Larger talent pool. ✅

Correct. Decentralization allows organizations to recruit, develop, and retain talent in different locations, rather than relying solely on headquarters for leadership roles.

This aligns with IIA Standard 2110 – Governance, which emphasizes the importance of leadership distribution and talent management in organizations.

(D) Strong internal controls.

Incorrect. Centralized structures typically have stronger internal controls, as decision-making and risk management are closely monitored. Decentralization increases the risk of inconsistent controls across different units.

IIA Standard 2110 – Governance

COSO Framework – Organizational Structure and Risk Management

IIA GTAG – "Auditing Business Strategy Alignment"

Analysis of Answer Choices:IIA References:Thus, the correct answer is C, as decentralization expands the talent pool by enabling local decision-making and leadership development.

Understanding the Accounting for Office Supplies:

The organization maintains an account for office supplies on hand, which represents unused office supplies at any given time.

The expense recorded during the year represents the cost of office supplies purchased.

At year-end, the adjusting entry is made to reflect the actual amount of supplies on hand and adjust the supplies expense accordingly.

Formula to Determine the Supplies Used:

Supplies Used=Beginning Balance+Purchases−Ending Balance\text{Supplies Used} = \text{Beginning Balance} + \text{Purchases} - \text{Ending Balance}Supplies Used=Beginning Balance+Purchases−Ending Balance

Plugging in the given values:

Supplies Used=9,000+45,000−11,500=42,500\text{Supplies Used} = 9,000 + 45,000 - 11,500 = 42,500Supplies Used=9,000+45,000−11,500=42,500

This amount ($42,500) represents the actual office supplies used and should be recorded as an expense.

The adjusting entry would include:

A debit to Office Supplies on Hand for $42,500

A credit to Office Supplies Expense for $42,500

Why Other Options Are Incorrect:

A. A debit to office supplies on hand for $2,500 – Incorrect, as this figure does not represent supplies used or purchased.

B. A debit to office supplies on hand for $11,500 – Incorrect, as this is the ending balance and not the adjustment amount.

C. A debit to office supplies on hand for $20,500 – Incorrect, as this does not align with the formula for calculating used supplies.

IIA’s Perspective on Financial Reporting and Adjusting Entries:

IIA Standard 1220 – Due Professional Care emphasizes accurate financial reporting and proper adjustments for year-end entries.

GAAP Accounting Principles require accrual-based adjustments to ensure that expenses are recognized in the period they are incurred.

COSO Internal Control Framework supports proper inventory and expense adjustments to avoid misstated financials.

IIA References:

IIA Standard 1220 – Due Professional Care (Financial Reporting Accuracy)

GAAP Accounting Standards – Adjusting Entries for Supplies and Inventory

COSO Internal Control – Accurate Expense Recognition

Thus, the correct and verified answer is D. A debit to office supplies on hand for $42,500.
