Where to Start When Reading the Notes to Financial Statements
Use major changes in the primary statements to find relevant accounting policies and detailed notes. Borrowing and receivable examples show how to select disclosures and frame useful questions.
The notes are part of the financial statements and explain the composition, measurement methods, estimates, and risks behind the primary figures. Rather than reading every note at the same pace from start to finish, identify important movements in the statements and follow the relevant note references. Reading the accompanying explanations reveals how the same account can have different meanings.
Turn questions about the statements into search terms for the notes
If trade receivables grow faster than revenue, look for their composition, loss allowances, and credit risk explanations. If borrowings fall but interest expense rises, check interest rates, balances during the period, currencies, and funding terms. Starting with one question makes the relevant tables easier to locate in lengthy notes. After reading a note, return to the primary statement and reconcile the totals. An item split into current and non-current portions in the statement may appear as a combined total in the note; comparing only one portion can create a false impression of a discrepancy.
Record policies, estimates, and outcomes separately
Accounting policies explain the principles used to account for transactions; estimates explain the assumptions used to measure uncertain amounts. Information that appears similar, such as depreciation methods, useful lives, and recoverability assumptions, may differ in nature. When current-period figures change, record whether the cause is a business change, an accounting policy change, or an estimate change. Correcting a past error and changing an estimate in light of new information affect comparative figures differently and should not both be described as the same type of correction.
Keep conclusions within the scope of the disclosures
Insufficient detail in a note does not establish that hidden losses exist. Conversely, the absence of a line in the primary statements does not establish that there are no guarantee or covenant risks. Check disclosures of significant commitments, collateral, and contingencies, and distinguish disclosed facts from your inferences. For items you plan to track, retain the source location and reporting date so you can compare changes in the next report. Quarterly notes may not repeat every explanation in the annual report, so keeping the latest annual notes alongside them is useful.
Worked example
Hypothetical example: All amounts below are in units of KRW 100 million. Current borrowings of 80 and non-current borrowings of 120 in the primary statement reconcile to a note total of 200, establishing that the scope agrees. Suppose the note then explains that 150 of the 200 bears floating interest rates and 50 bears fixed rates. To investigate exposure to rising interest rates, start with the floating-rate 150 rather than total liabilities. Checking for hedging contracts brings the analysis closer to net interest rate exposure; one number from a note cannot establish the entire interest expense.
What to check
- Turn one movement in the primary statements into a question.
- Reconcile the relevant note total and its current and non-current scope.
- Distinguish policy changes, estimate changes, and error corrections.
- Connect annual notes with explanations of changes in the latest quarter.
