Explore how companies transition from local GAAP to IFRS under IFRS 1, including common adjustments, optional exemptions, and the impact on key financial ratios.
When an entity moves from local GAAP—or any other existing accounting framework—to International Financial Reporting Standards (IFRS), IFRS 1, “First-time Adoption of International Financial Reporting Standards,” provides the rules of the road. In essence, IFRS 1 guides first-time adopters in preparing an opening IFRS balance sheet and sets the stage for consistent, comparable financial statements going forward. This transition can involve quite a bit of heavy lifting: reevaluating the classification and measurement of assets and liabilities, dealing with new disclosures, adjusting for differences in revenue and expense recognition, and perhaps the most challenging part—explaining all these changes to investors, regulators, and other stakeholders.
Sometimes you’ll hear folks say, “Oh, IFRS 1, that’s just about re-labeling the financial statements.” Um, no, definitely not. I remember working alongside a colleague who was in charge of the IFRS transition for a mid-sized manufacturing firm. She spent weeks consulting with auditors, going back and forth on the optional exemptions for property, plant, and equipment (PPE) revaluation, not to mention the deferred tax nuances. It was basically a puzzle, and each piece had to fit just right for the opening IFRS balance sheet to tie out. And you know what? She said afterward that the biggest challenge wasn’t even the mechanical revaluations; it was ensuring that everyone—from the CFO to the operations managers—understood how and why the numbers were evolving. IFRS 1 is a big deal, as it sets the tone for future financial reporting clarity and credibility.
Below, we’ll walk through the fundamentals of IFRS 1, provide a structured example of what the reconciliation statements might look like, and highlight the optional exemptions that can drive material differences in the final outcome. We’ll also examine the effect on common financial ratios—like profit margins, coverage ratios, or leverage metrics—and discuss best practices for exam day and real-world application.
IFRS 1 requires a new IFRS adopter to present:
• An opening IFRS balance sheet at the date of transition.
• Reconciliations of equity under local GAAP to equity under IFRS (both for the date of transition and the end of the latest period reported under the previous framework).
• A reconciliation of total comprehensive income under local GAAP to IFRS for the latest annual or interim period.
• Explanations of the material adjustments made in restating local GAAP to IFRS.
The idea is that users of financial statements—investors, analysts, regulators—should see exactly how a company’s reported financial position and performance changed under the new recognition and measurement rules. And they shouldn’t have to guess: IFRS 1 prescribes explicit disclosure requirements so that no major differences go unexplained.
Let’s consider some typical areas where you might see big swings or reporting differences as a result of IFRS 1’s requirements:
Property, Plant, and Equipment (PPE).
Under local GAAP, an entity could use a certain depreciation method or might capitalize certain overhead costs differently. IFRS might mandate a revised approach to useful lives, or it might allow revaluation of assets to fair value (provided the entity elects that revaluation policy). So you end up with a different carrying amount for PPE on Day 1 of IFRS adoption, which in turn drives changes in depreciation expense going forward.
Deferred Taxes.
The fun never ends with deferred tax accounting. IFRS draws a line between temporary differences (those that arise from differences in tax bases of assets/liabilities and their carrying amounts) and permanent differences. The recognition of deferred tax assets might be more restrictive or more liberating, depending on your local GAAP. Then factor in IFRS standards on uncertain tax positions or tax effect from revaluation gains—these changes can alter both the statement of financial position (balance sheet) and the statement of profit or loss.
Financial Instruments.
Some frameworks classify financial instruments in a manner that is drastically different from IFRS 9 or IAS 39 (the older standard, if you still reference pre-IFRS 9 contexts). Under IFRS, classification and measurement revolve around the entity’s business model and contractual cash flow characteristics. This can lead to:
• Reclassifications from “held-to-maturity” or “available-for-sale” to IFRS categories such as “fair value through profit or loss” or “fair value through other comprehensive income.”
• Remeasurement of carrying values, plus the need to adjust for expected credit losses under IFRS 9, which can differ from any local “incurred loss” or alternative approach.
IFRS 1 acknowledges that a full, back-to-birth retrospective application of IFRS might be too complicated or even impossible. So it offers certain optional exemptions. Entities can choose some of these “one-time deals” to mitigate the cost or complexity of adopting IFRS for the first time. A few examples:
• Exemption for Business Combinations. Instead of restating all prior acquisitions to comply with IFRS 3’s measurement and recognition criteria (e.g., goodwill, intangible assets, etc.), an entity may choose to apply IFRS 3 prospectively from the date of transition.
• Deemed Cost Exemption. A company can elect to measure items of property, plant, and equipment, intangible assets, or investment property at fair value on the transition date. This becomes the “deemed cost” going forward, avoiding the need for retrospective calculations of depreciation or revaluation.
• Leases. Under IFRS 16, all leases are recognized on the balance sheet by the lessee (with limited exceptions). Numerous transitional reliefs or exemptions exist to simplify the measurement of lease liabilities and right-of-use assets upon first adoption.
To illustrate the logic of presenting an opening balance sheet, plus how local GAAP amounts shift into IFRS, consider the conceptual flow in the diagram below. This is a simple way to envision the transformation from local GAAP to IFRS for a hypothetical company, “ABC Manufacturing.”
flowchart LR A["Local GAAP Balance Sheet <br/> (Year-End 2025)"] --> B["Identify IFRS Adjustments <br/> (IFRS 1 Requirements)"] B --> C["Adjustments to: <br/>1. PPE <br/>2. Deferred Taxes <br/>3. Financial Instruments <br/>...etc"] C --> D["Opening IFRS Balance Sheet <br/> (Transition Date: Jan 1, 2026)"] D --> E["Comparative IFRS <br/> Financials for 2026"]
As you can see, the first step is identifying all relevant IFRS adjustments. Next, those adjustments feed into the opening IFRS balance sheet. Finally, the company moves forward preparing IFRS-based comparative financials.
Let’s do a simple numeric example where a company transitions on January 1, 2026. We’ll assume local GAAP had certain line items, and IFRS adjustments shift amounts at the transition date. You’ll see how the IFRS 1 reconciliation statement might look.
Here are the hypothetical local GAAP balances for “XYZ Corporation” on December 31, 2025 (the last reporting date under local GAAP), along with the IFRS 1 adjustments (in thousands of currency units):
Account | Local GAAP (12/31/25) | IFRS 1 Adjustments | IFRS Opening (1/1/26) |
---|---|---|---|
Property, Plant, and Equipment | 50,000 | +1,000 | 51,000 |
Accumulated Depreciation | (20,000) | +800 | (19,200) |
Deferred Tax Liability | (2,000) | -500 | (2,500) |
Financial Assets (Held-to-Maturity) | 5,000 | +300 (FV adj.) | 5,300 |
Share Capital | 10,000 | — | 10,000 |
Retained Earnings | 15,000 | +1,600 | 16,600 |
Explanations of Adjustments:
• Property, Plant, and Equipment: Under local GAAP, the entity had historically used straight-line depreciation but had not fully unbundled certain component parts. IFRS requires component depreciation for significant parts, which effectively lengthened the remaining useful life of some major components. That triggered a net increase in PPE’s carrying amount (and a partial reversal of accumulated depreciation).
• Deferred Tax: The partial reversal of depreciation also changed the temporary differences for tax bases, increasing deferred tax liabilities by 500.
• Financial Assets: Reclassified from “held-to-maturity” to “fair value through other comprehensive income” under IFRS, resulting in a 300 fair value gain.
• Equity Adjustments: The net effect of these adjustments (1,000 net increase in PPE minus 800 for accumulated depreciation plus 300 gain on financial assets minus 500 additional deferred tax liability) flows through to retained earnings, giving a net 1,600 boost there.
You might then see a formal statement such as:
• Equity Under Local GAAP (12/31/25): 25,000 (Share Capital of 10,000 + Retained Earnings of 15,000).
• Adjustments for IFRS Adoption: 1,600 (PPE + financial assets gains – deferred tax changes).
• Equity Under IFRS (1/1/26): 26,600.
After adoption, certain headline ratios will shift. If your depreciation expense is lower under IFRS, you might see a higher operating margin. If revaluation of PPE leads to a bigger asset base while you keep the same capital structure, your leverage (e.g., Debt-to-Equity) might go down. Meanwhile, changes to recognized deferred tax liabilities or intangible assets could impact the quick ratio or other coverage metrics.
These swings can be confusing to external stakeholders. That’s why IFRS 1’s robust reconciliation and disclosure requirements are so valuable. They give analysts the clarity they need to recast historical financial statements and evaluate trends more consistently.
When presenting an IFRS 1 reconciliation, keep in mind:
• Narrative Explanation: You’ll typically see footnotes or notes to the financial statements specifying exactly how the numbers changed, the rationale for adopting certain optional exemptions, and the method used to estimate fair values.
• Comparative Period: First-time adopters must generally produce at least one year of comparative IFRS financial statements. This includes restating local GAAP financials into IFRS for that prior period.
• Reconciliation Format: Entities often disclose a table that starts with local GAAP equity or profit, then columns reflecting adjustments for major items (e.g., intangible assets, leases, deferred taxes), culminating in the IFRS figure.
Selecting or foregoing certain IFRS 1 exemptions can dramatically change the opening balance sheet and future financial statements. A couple of real-world examples:
• Deemed Cost for PPE: If an airline opts to use fair value as deemed cost for its fleet, the carrying value of all aircraft might jump significantly, with an enormous offset to retained earnings. Alternatively, if the airline chooses not to revalue, it might retain lower historical costs.
• Business Combinations: If a holding company decides not to restate prior acquisitions, it can avoid re-recognizing intangible assets or adjusting goodwill. This approach can reduce complexity but might limit comparability with peers who adopt IFRS with more retrospective rigor.
I recall an instance—this was at a consumer goods firm—where an optional exemption significantly shaped the story investors saw. The management team elected the deemed cost exemption for a major property that had appreciated significantly. In local GAAP, that building was still recognized at a 1980s-era cost. Under IFRS, they took one look at the fair value and basically went, “Wow, that’s a major difference.” The revaluation soared by 75%, and the company’s opening IFRS equity jumped by about 25% overnight. The CFO told me that while it was great for the balance sheet optics, they also had to think carefully about future depreciation expense and the impact on key metrics. So making these elections is not just an accounting exercise but also a strategic one.
With IFRS 1 transitions generating reams of new data—adjustments to thousands of fixed assets or recalculations of intangible asset values—data analytics can be used to identify the biggest divergences. This is often done by scanning large asset registers for items that show massive measurement shifts between local GAAP and IFRS assumptions (e.g., different residual values, revalued intangible assets, etc.). If you’re preparing for the exam, it’s good to note that IFRS 1 is often tested in short item-set or mini-case scenarios that require knowledge of typical adjustments and the rationale behind them.
• Documentation: Document the reasons for each IFRS 1 adjustment. Not only is this essential for the external audit, but it also helps your finance teams replicate the logic in future years.
• Communication: Don’t forget the investor call or press release explaining major changes. IFRS 1 can be disorienting to non-accountants if left unexplained.
• Exemption Overload: Be cautious when adopting multiple exemptions. If you rely on too many short-cut approaches, you might hamper the comparability of your own financial statements over time.
• Tax Implications: Revaluation adjustments might trigger current or deferred tax liabilities. Always cross-check with local tax regulations to see if IFRS-based remeasurements create or dissolve any tax differences.
• Systems Upgrades: Make sure your accounting information systems are up to the challenge. IFRS can require more granular detail. “Component depreciation,” for instance, needs robust asset management software.
Occasionally, a CFO or controller might want to quickly confirm the net effect of IFRS adjustments. Below is a trivial Python snippet that sums up adjustments and prints the IFRS opening values, just to illustrate how some teams do a quick data check.
1local_gaap = {
2 'PPE': 50000,
3 'AccDep': -20000,
4 'DefTaxLiab': -2000,
5 'FinancialAssets': 5000,
6 'ShareCap': 10000,
7 'RE': 15000

16
17ifrs_opening = {}
18for item in local_gaap:
19 if item in adjustments:
20 ifrs_opening[item] = local_gaap[item] + adjustments[item]
21 else:
22 ifrs_opening[item] = local_gaap[item]
23
24adjustments_sum = sum(adjustments.values())
25ifrs_opening['RE'] = local_gaap['RE'] + adjustments_sum
26
27print("IFRS Opening Balances:")
28for key, val in ifrs_opening.items():
29 print(key, val)
If you run this snippet, you’d see IFRS opening PPE, accumulated depreciation, deferred tax liability, and so on. This is oversimplified, but it can be helpful for internal spot checks.
• Focus on the Mechanics: The exam will often give you local GAAP numbers, list a set of IFRS 1 adjustments, and ask for the IFRS opening equity or net income. Make sure you track each item carefully; watch for the offset in retained earnings.
• Identify IFRS 1 Optional Exemptions: If a question references a revaluation of PPE or intangible assets, that might be an IFRS 1 “deemed cost” type of scenario. Look for the practical reasons and the effect on the balance sheet.
• Watch Ratios and Trend Analysis: Keep your eye on how the IFRS changes affect solvency and profitability metrics. The exam could ask how these changes differ from local GAAP so you can identify if those changes are beneficial or detrimental to an analyst’s view of the company.
• Comprehensive Reconciliation: Practice a step-by-step approach: Start with local GAAP equity → sum the IFRS adjustments → verify the final IFRS equity. Then separately reconcile the statement of comprehensive income if needed.
• Keep an Eye on Disclosures: IFRS 1 requires robust disclosures explaining the nature and amounts of adjustments. Don’t forget that narrative explanations are a big deal in IFRS 1.
To drill deeper into IFRS 1 transitions and see real-life examples of first-time adoption, consider:
• The IFRS 1 Transition Examples on the official IFRS website (https://www.ifrs.org).
• Steven E. Shamrock’s “IFRS and US GAAP: A Comprehensive Comparison.”
• Historical SEC filings of companies that switched from local GAAP to IFRS—these can sometimes be found in cross-listed companies’ annual reports.
IFRS 1 transitions can initially feel like a labyrinth of asset revaluations, deferred tax recalculations, and recalibrated financial instruments. But once you understand the fundamental building blocks of first-time adoption—opening balance sheet, reconciliations of equity, and total comprehensive income (plus the optional exemptions)—it all starts to make sense. The result is a set of financial statements that align with IFRS standards and hopefully aid in cross-border comparability.
If you’re tackling this topic for the CFA exam or for a real business scenario, remember: bridging the gap between local GAAP and IFRS isn’t just about the mechanics. It’s about telling a coherent story of how the company’s financial position, performance, and risk profile have changed under IFRS. Clarity and transparency will always be your best allies.
