Completing the Accounting Cycle and Internal Control

TL;DR

Completing the accounting cycle involves steps like adjusting entries, closing temporary accounts, and preparing financial statements to ensure accurate reporting. Internal controls are crucial policies and procedures designed to protect assets, ensure reliable financial data, and promote operational efficiency. Together, they form the backbone of trustworthy financial record-keeping and business operations.

1. The Mental Model

Think of the accounting cycle as a continuous loop that keeps a business's financial picture clear and accurate, much like a regular health check-up. Internal controls are the safeguards and good habits you put in place to ensure that check-up process is honest and that no one messes with the results.

2. The Core Material

After recording transactions throughout an accounting period, there are several crucial steps to finalize the books and prepare for the next period. This is "completing the accounting cycle." Alongside this, businesses must implement "internal controls" to protect their assets and ensure their financial data is reliable.

The Accounting Cycle: The Final Steps

The accounting cycle typically has 10 steps, but we'll focus on the closing steps after the initial recording and trial balance.

1. Adjusting Entries: These are made at the end of an accounting period to record revenues in the period they are earned and expenses in the period they are incurred (accrual accounting). They ensure that the financial statements reflect the true financial position and performance. Examples include depreciation, accrued salaries, and using up supplies.
2. Adjusted Trial Balance: After posting adjusting entries, a new trial balance is prepared. This ensures that debits still equal credits and that all accounts are ready for financial statement preparation.
3. Financial Statement Preparation: From the adjusted trial balance, you prepare the main financial statements:
   • Income Statement: Shows revenues and expenses over a period, resulting in net income or loss.
   • Statement of Retained Earnings: Shows changes in retained earnings over a period.
   • Balance Sheet: Presents assets, liabilities, and equity at a specific point in time.
   • Statement of Cash Flows: Details cash inflows and outflows.
4. Closing Entries: These entries transfer the balances of all temporary accounts (revenues, expenses, dividends) to a permanent account, usually Retained Earnings. This resets the temporary accounts to zero for the next accounting period.
5. Post-Closing Trial Balance: This final trial balance lists only permanent accounts (assets, liabilities, equity) and verifies that debits equal credits after closing entries have been posted. This confirms the balance sheet accounts are ready for the next period.

Internal Control: Guarding Your Business

Internal control is a process designed and implemented by management to provide reasonable assurance about the achievement of objectives in three areas:
* Effectiveness and efficiency of operations: Are things running smoothly and profitably?
* Reliability of financial reporting: Is the financial data accurate and trustworthy?
* Compliance with applicable laws and regulations: Is the business following the rules?

Key principles of internal control include:

• Segregation of Duties: No single employee should be responsible for all parts of a transaction (e.g., authorizing, recording, and custody of assets). This reduces opportunities for fraud or error.
• Physical Controls: Securing assets, like locked cash registers, safes, and security systems.
• Documentation: Proper records (pre-numbered documents, invoices, receipts) provide an audit trail.
• Independent Internal Verification: Regular reviews and reconciliations performed by someone not involved in the original transactions.
• Human Resource Controls: Background checks, regular vacations for employees, and clear job descriptions.

3. Worked Example

Let's trace a simple adjusting entry and its effect.

Imagine on December 31, a company, "Fresh Flowers Inc.," has an Unadjusted Trial Balance showing Supplies on hand of \$2,000. During the month, they estimate they used \$1,200 worth of supplies.

1. Adjusting Entry (December 31):
   To recognize the supplies used as an expense:

   • Debit: Supplies Expense \$1,200 (Increases an expense account)
   • Credit: Supplies \$1,200 (Decreases an asset account)

   This entry moves the value of the consumed supplies from the asset account (Supplies) to an expense account (Supplies Expense), reflecting that they've been used up.

2. Effect on Accounts:

   • Supplies (Asset): Starting balance \$2,000. After credit of \$1,200, the new balance is \$800. This correctly shows the value of supplies still on hand.
   • Supplies Expense (Expense): Starting balance \$0. After debit of \$1,200, the new balance is \$1,200. This correctly shows the cost of supplies used during the period.

3. Impact on Financial Statements:

   • The Income Statement will now include \$1,200 in Supplies Expense, accurately reducing net income for the period.
   • The Balance Sheet will show Supplies as an asset at \$800, accurately reflecting the remaining asset value.

4. Closing Entry (Year-end):
   Later, when closing temporary accounts, the \$1,200 balance in "Supplies Expense" will be debited to Retained Earnings and credited to Supplies Expense, making the Supplies Expense account balance zero for the start of the next period.

This ensures both the income statement and balance sheet are accurate after adjustments.

4. Key Takeaways

• Adjusting entries are vital for accurate financial reporting, aligning revenues with when they're earned and expenses with when they're incurred.
• The adjusted trial balance is a critical checkpoint to ensure debits still equal credits after adjustments and before financial statement preparation.
• Financial statements (Income Statement, Balance Sheet, etc.) are compiled directly from the adjusted trial balance, offering a comprehensive view of the company's performance and position.
• Closing entries zero out temporary accounts (revenues, expenses, dividends), preparing them for the next accounting period and transferring their net effect to Retained Earnings.
• The post-closing trial balance confirms that only permanent accounts carry balances forward, ensuring a clean slate for the new period.
• Internal controls are proactive measures designed to protect assets, prevent errors and fraud, and ensure the reliability of financial data.
• Segregation of duties is a cornerstone of effective internal control, preventing one person from having too much power over a transaction.

Common Mistakes to Avoid:
- Forgetting to make necessary adjusting entries, which leads to misstated financial statements.
- Not performing a post-closing trial balance, missing potential errors in the closing process.
- Neglecting to implement or review internal controls, leaving a business vulnerable to fraud or error.
- Confusing temporary accounts (which get closed) with permanent accounts (which carry balances forward).

5. Now Try It

Imagine your company, "TechGadget Co.," paid \$6,000 for one year of insurance on October 1.
1. Calculate: How much insurance expense should be recognized by December 31?
2. Journalize: Record the adjusting entry needed on December 31.
3. Explain: What would be the impact on the Income Statement and Balance Sheet if this adjusting entry was not made?

Success means you've correctly calculated the expense, journalized the entry, and can clearly describe the consequences of its omission for both financial statements.
