Introduction

The Grand Historian records: Just as the ancient kingdoms each maintained their own systems of weights and measures — creating chaos at every border — so too have the nations of the modern world maintained their own accounting standards. The result is a Babel of financial reporting, where the same transaction may be recorded differently in New York, London, Tokyo, and Taipei.

Two great standards now dominate the financial world: US GAAP (Generally Accepted Accounting Principles), the law of the American financial empire, and IFRS (International Financial Reporting Standards), adopted by over 140 countries worldwide. Understanding both — and their differences — is essential for any accountant who operates beyond a single border.

What Are Accounting Standards?

Accounting standards are authoritative rules that dictate how transactions and events should be recognized, measured, presented, and disclosed in financial statements. They exist to ensure:

  • Comparability: Investors can compare financial statements of different companies.
  • Consistency: Companies apply the same methods from period to period.
  • Transparency: Financial information is clear and understandable.
  • Reliability: Users can trust that the numbers reflect economic reality.

US GAAP: The American Standard

US GAAP is set by the Financial Accounting Standards Board (FASB), a private-sector body established in 1973. The SEC has delegated the authority to establish accounting standards to the FASB, making its pronouncements effectively law for all US public companies.

Key Characteristics of GAAP

  • Rules-based: Highly specific and detailed, with extensive guidance for specific industries and transactions.
  • Codified: Organized in the Accounting Standards Codification (ASC), with topics numbered from ASC 105 to ASC 860.
  • US-focused: Required for companies listed on US stock exchanges and filing with the SEC.
  • Conservative: Generally prefers historical cost and has stricter rules about asset revaluation.

IFRS: The International Standard

IFRS is set by the International Accounting Standards Board (IASB), based in London. Over 140 countries require or permit IFRS for their listed companies, making it the most widely used set of accounting standards in the world.

Key Characteristics of IFRS

  • Principles-based: Provides broad principles rather than detailed rules, relying on professional judgment.
  • Flexible: Allows revaluation of certain assets to fair value.
  • Global scope: Used in the EU, Australia, Canada, Japan (permitted), Taiwan (adopted), and most of Asia, Africa, and South America.
  • Evolving: Continuously updated as the IASB issues new standards (IFRS 1 through IFRS 17 and counting).

Key Differences Between IFRS and GAAP

Area US GAAP IFRS
Approach Rules-based Principles-based
Inventory LIFO allowed LIFO prohibited
Asset revaluation Generally prohibited Allowed for certain assets
Development costs Expensed as incurred Capitalized if criteria met
Impairment reversal Not allowed Allowed (except goodwill)
Income statement Single-step or multi-step No prescribed format, but requires certain line items
Extraordinary items Prohibited (since ASU 2015-01) Prohibited
Lease classification Finance vs. operating (ASC 842) Single model — most leases on balance sheet (IFRS 16)

Other Important Standard-Setters

  • GASB (Governmental Accounting Standards Board): Sets standards for US state and local governments.
  • IPSASB (International Public Sector Accounting Standards Board): Sets standards for public sector entities internationally.
  • AICPA: The American Institute of Certified Public Accountants provides guidance and ethics codes for the CPA profession.
  • SEC: While not a standard-setter per se, the SEC has the ultimate authority over financial reporting for US public companies and can override FASB.

The Quest for Global Convergence

For decades, the FASB and IASB have worked toward converging GAAP and IFRS into a single global standard. Significant progress has been made — revenue recognition (ASC 606 / IFRS 15) and leases (ASC 842 / IFRS 16) were joint projects. However, full convergence remains elusive:

  • The US has not adopted IFRS for domestic companies, despite considering it multiple times.
  • Cultural, legal, and political differences across countries create resistance to a single standard.
  • The rules-based vs. principles-based philosophical divide persists.

For the foreseeable future, accountants who work internationally must be fluent in both frameworks — a bilingual requirement in the language of business.

Key Takeaways

  • US GAAP (set by FASB) is rules-based and used primarily in the United States.
  • IFRS (set by IASB) is principles-based and used in over 140 countries worldwide.
  • Key differences include inventory methods (LIFO), asset revaluation, development costs, and impairment reversal.
  • Convergence efforts have produced aligned standards (revenue, leases) but full unification is unlikely soon.
  • Accountants operating internationally must understand both frameworks.

概述

  • 學習目標:主要會計準則(IFRS 和 GAAP)、準則制定機構(FASB 和 IASB)、框架間的關鍵差異,以及全球趨同之路。
  • 先決條件:第 7 課——內部控制與倫理
  • 預計閱讀時間:15 分鐘

簡介

太史公曰:古之列國各有度量衡——每至邊界則混亂叢生——今之世界各國亦各有會計準則。結果是財務報告之巴別塔,同一交易在紐約、倫敦、東京、台北可能記錄方式迥異。

兩大準則今主宰財務世界:US GAAP(美國一般公認會計原則),美國金融帝國之法典;IFRS(國際財務報導準則),全球超過 140 個國家採用。

US GAAP:美國準則

  • 規則導向:高度具體且詳細。
  • 由 FASB 制定:1973 年設立之私部門機構。
  • 適用於美國上市公司。

IFRS:國際準則

  • 原則導向:提供廣泛原則而非詳細規則。
  • 由 IASB 制定:設於倫敦。
  • 全球超過 140 國採用,包括歐盟、澳洲、加拿大、台灣。

IFRS 與 GAAP 之主要差異

領域 US GAAP IFRS
方法 規則導向 原則導向
存貨 允許 LIFO 禁止 LIFO
資產重估 一般禁止 允許特定資產
開發成本 發生時費用化 符合條件時資本化
減損迴轉 不允許 允許(商譽除外)

全球趨同之路

FASB 與 IASB 多年來致力於將 GAAP 與 IFRS 趨同為單一全球準則。已有重大進展——收入認列(ASC 606 / IFRS 15)與租賃(ASC 842 / IFRS 16)為聯合專案。然完全趨同仍遙不可及。

重點摘要

  • US GAAP(FASB 制定)為規則導向,主要用於美國。
  • IFRS(IASB 制定)為原則導向,全球超過 140 國使用。
  • 主要差異包括存貨方法、資產重估、開發成本、減損迴轉。
  • 國際營運之會計師須通曉兩種框架。

概要

  • 学習内容:主要な会計基準(IFRSとGAAP)、基準設定機関(FASBとIASB)、フレームワーク間の主要な違い、グローバル・コンバージェンス。
  • 前提条件:レッスン7——内部統制と倫理
  • 推定読了時間:15分

はじめに

太史公曰く:古の列国がそれぞれ独自の度量衡を維持し、国境ごとに混乱を招いた如く、現代の国家もそれぞれ独自の会計基準を維持している。結果は財務報告のバベルの塔——同じ取引がニューヨーク、ロンドン、東京、台北で異なる記録方法を取る。

二つの大基準が今日の財務世界を支配する:US GAAPIFRS

US GAAP:アメリカの基準

  • ルールベース:高度に具体的かつ詳細。
  • FASBが策定:1973年設立の民間機関。
  • 米国上場企業に適用。

IFRS:国際基準

  • 原則ベース:詳細なルールではなく広い原則を提供。
  • IASBが策定:ロンドンに本拠。
  • 140カ国以上で採用。日本では任意適用。

IFRSとGAAPの主要な違い

分野 US GAAP IFRS
アプローチ ルールベース 原則ベース
棚卸資産 LIFO許容 LIFO禁止
資産再評価 原則禁止 特定資産で許容
開発費 発生時に費用化 基準を満たせば資産計上
減損の戻入 不可 可能(のれん除く)

グローバル・コンバージェンスの道

FASBとIASBは数十年にわたりGAAPとIFRSの統合に取り組んできた。収益認識とリースは共同プロジェクトとして成果を上げたが、完全統合はなお遠い。

重要ポイント

  • US GAAP(FASB策定)はルールベースで、主に米国で使用。
  • IFRS(IASB策定)は原則ベースで、140カ国以上で使用。
  • 主要な違いは棚卸資産方法、資産再評価、開発費、減損の戻入。
  • 国際的に活動する会計士は両フレームワークを理解する必要がある。
