I didn’t expect to enjoy reading about accounting. I picked up this book thinking I’d slog through another dry technical manual, but Christopher Nobes writes with the kind of enthusiasm you’d expect from someone who finds satisfaction in reconciling accounts. His passion for the subject came through, and I found myself smiling at his obvious delight in the details.
The book explores accounting not as a set of rigid rules but as a practice shaped by history, judgment, and the messy realities of standardizing across different countries. Nobes goes beyond the mechanics to show how accounting has evolved and why so many decisions rely on judgment calls rather than strict formulas. One example stuck with me: valuing assets. Should you use selling price, market price, original cost, or business worth? There’s no single right answer, and the choice depends on context. This is where accounting becomes an art.
The historical perspective helped me understand why accounting practices look the way they do today. Knowing the evolution behind IFRS and how it compares to GAAP made sense of the inconsistencies I’ve encountered working with financial data. The global view also highlighted the challenges of achieving consistency across cultures and economies. Standards exist, but interpretation and application vary widely.
One idea I’m still wrestling with is the treatment of employee training as an expense rather than an asset. I understand the reasoning. You don’t control your employees the way you control physical assets. But in a knowledge-driven economy, investing in people feels more like building something durable than incurring a cost. The distinction feels too clean to me. The line between assets and expenses is blurrier than the book suggests.
I also appreciated the section on budgeting. Nobes frames it not only as a financial tool but as a way to force executives to think through their plans in detail and hold themselves accountable. This framing shifts budgeting from tedious busywork to a strategic exercise.
If you work in business or with financial data and want to understand accounting beyond the surface level, read this book. If you’re looking for a how-to guide on bookkeeping, skip it. This book is for people who want to think about accounting, not just do it.
Nobes quotes, “lies, damned lies, statistics, and financial statements.” It’s a reminder that accounting aims for objectivity but remains subject to interpretation. The book doesn’t shy away from this tension, and I respect that honesty.

The book of rules of International Financial Reporting Standards is over 3,600 pages long this year; and the equivalent book of US rules is much longer.
Financial accounting is the use of accounting data in order to calculate and report the cash flows, profit and financial position of an entity.
In much of the world, various forms of law impose ‘accounting standards’ on companies, particularly on listed companies. The standards are written by committees of accountants; the most important being the International Accounting Standards Board (IASB).
In some countries (e.g. Germany and Italy), tax and accounting are very closely linked, so that expertise in one field automatically implies expertise in the other. In other countries (e.g. the USA and the UK), the main purpose of accounting is to give useful financial reports to investors.
Another field related to accounting is finance, which is concerned with the raising of money and how to best use it. Finance addresses such questions as: If a company wishes to expand, should it borrow money or should it get more money from its owners? If a company has spare money, should it invest in new projects, pay dividends to the shareholders, buy back its own shares, or pay off its debts?
This book focusses on the central areas of accounting (financial reporting and management accounting) and does not have space to examine the areas of insolvency, tax, consultancy, and finance.
Each time a shop sells something, a bank lends money or a manufacturer pays the wages, a record must be kept. The process of recording all the transactions is called bookkeeping. […] the technique used is nearly always ‘double-entry bookkeeping’, which is an Italian invention of the thirteenth century. It is famous for its debits and credits. […] Financial accounting information is prepared in summarized form for people outside of the entity, such as shareholders. The process of sending such information is called financial reporting. […] The financial reports include an income statement and a balance sheet.
One major reason for needing to keep account is so that the stewards of resources can later give an account to the owner of what they did with the resources. Originally, this was the high officials giving account to temple complexes or kings. Now, it is the directors of a company giving account to its shareholders.
Debits and credits are the positive and negative elements of the double-entry system but they pre-date it.
At some point in the thirteenth century, it became clear that all transactions could be seen as having two aspects. However, this involved inventing accounts for increasingly abstract things, such as sales or wages.
When the profit is added to the owner’s interest, the balance sheet will balance. This is a very satisfying result, rather like finishing a Sudoku or a crossword.
There were different versions of double entry, notably a Tuscan one and a Venetian one. The latter had the clearer two-sided presentation.
Bristol is a good English analogy for Genoa; they were both important trading ports. Boats were going between the cities throughout the four and a half centuries that it took for double entry to pass from Genoa town hall to Bristol town hall.
[S]ome company failures involved massive losses, for example the City of Glasgow Bank in 1878. This led to the requirement for audit by outside experts, initially for banks, and then for all companies from 1900. Britain had invented the widespread publication of audited financial statements.
A balance sheet is a document designed to show the state of affairs of an entity at a particular date. Its official International Financial Reporting Standards (IFRS) name is ‘statement of financial position’.
One modern definition of ‘asset’ is that used by the International Accounting Standards Board (IASB): An asset is a resource controlled by the entity as a result of past events and from which future economic benefits are expected to flow to the entity.
The IASB defines a liability as: a present obligation of the entity arising from past events, the settlement of which is expected to result in an outflow from the entity of resources embodying economic benefits.
[G]iving primacy to the definition of ‘expense’ (and ‘income’), was the traditional way of doing accounting. It concentrates on transactions in a period. It leaves assets (and changes in their values) as a secondary consideration. However, from the 1970s onwards there have been moves towards […] giving primacy to the definition of ‘asset’ (and ‘liability’).
It is important to note that a cash increase and profit are not the same things. As noted immediately above, some transactions involve a change in cash with no profit, and some involve a profit with no change in cash.
A large majority of listed companies in the world follow International Financial Reporting Standards (IFRS) or US ‘generally accepted accounting principles’ (US GAAP) when preparing their consolidated statements.
[A]ssets have limited useful lives: they wear out because of usage (e.g. machines) or because time passes (e.g. patents). The obvious exception is land, which can last forever.
Generally, accountants use a really simple method for calculating depreciation: they charge equal amounts to each year. This is called straight-line depreciation.
Inventories do not normally wear out over time because an entity hopes to sell them quickly, so accountants do not depreciate them. However, in the case of damage or obsolescence, some immediate recognition of the loss is needed.
Research costs might well meet the definition of asset, but accountants are so unsure about the future benefits that such costs are treated as expenses.
A liability is defined in IFRS as: a present obligation caused by a past event expected to lead to future outflows.
Why would trained and loyal staff not be ‘assets’ of their employing company? The company is probably expecting future benefits from staff, and has had transactions with them in the past. However, staff can resign—often with little notice. […] So, staff are not ‘controlled’. For this reason, they are not treated as assets. This also means that training courses and other costs related to staff are treated as expenses rather than assets.
Some of the income and expenses are regarded as so far from cash or so removed from the control of the directors that they are shown separately as ‘other comprehensive income’ (OCI). Unfortunately, there is no clear principle to explain which these items are, only some complicated rules.
The income statements could be seen as being divided into three types of item: operating, financial, and other. However, there is no clear definition of any of these terms. So, practice varies somewhat between companies.
A liquidity ratio assesses whether a firm can meet its current obligations from its current assets. That is, can the company pay off its debts as they arise in the short-term? […] There is no particular good or bad size for this ratio. It depends on which type of industry the company is in. However, a danger signal would be if the ratio is falling, or if it is much lower than that of other companies in the same industry.
A financial structure ratio measures how much the firm is funded by equity capital and how much by debt capital, in other words, what proportion of the funds comes from the owners and what proportion from outside lenders (such as the banks). This ratio is known as ‘gearing’ or ‘leverage’.
To extend the continuum of ability to mislead (attributed to Disraeli), there are lies, damned lies, statistics, and financial statements. However, that does not mean that statistics and financial statements cannot be useful. It means that they must be interpreted carefully.
The basic reason for international differences in accounting is that the main purpose of accounting has varied by country and over time. For example, by the last quarter of the twentieth century, the purpose for listed companies in the USA was to give useful information to investors to help them to predict cash flows in order to make economic decisions. By contrast, the purpose for most German companies was to calculate taxable income and prudently distributable profit.
IFRS is required for the consolidated statements of listed companies in the EU. The same applies in Australia, Canada, Hong Kong, New Zealand, South Africa, and several other countries. In China, listed companies use a set of Chinese accounting standards based approximately on IFRS. In Japan and Switzerland, IFRS is allowed but not required.
What effects on the balance sheet and the profit will be caused if the accountants assume LIFO rather than first-in first-out (FIFO)? The answer is that it would make the balance sheet look worse (older, cheaper inventory) and the profit worse (using up newer, dearer inventories in the calculation of profit). Why might a company want those effects? One possibility is that, if the tax calculation is tied to the income statement, then a lower profit will be useful.
The culmination of the audit process is the publication of an ‘opinion’ on whether the financial statements give a ‘true and fair view’ (UK) or ‘fair presentation’ (USA) of the company’s cash flows, financial position and profit or loss, in the context of the prevailing law and accounting rules.
The idea of ‘fairness’ reflects the fact that accounting is not an exact science and that there may be a number of different ways in which to present broadly similar information. The term conveys the idea that the financial statements have been honestly prepared to reflect the facts, and are not misleading to readers.
Naturally, investors who will have no active part in the management of the company, and may not even know those who are running it, deserve some protection from unscrupulous and incompetent managers. […] An important safeguard is the right to receive financial statements from the directors showing the profit of the company and its state of affairs, together with quite a lot of detailed information as required by various regulations.
[Financial accounting] The information is designed to make managers accountable to owners, and to assist investors with economic decisions. Typical financial documents produced under this category are: the income statement, the balance sheet, and the cash flow statement.
[Management accounting] The information is designed to assist managers with internal decisions and to help them control organizations. Typical financial documents produced under this category are: costing reports, break-even reports, and budgets (e.g. cash budgets).
Any costs that cannot be directly related to particular units of output are collected together in ‘cost centres’ (e.g. a production line or the head office) and then allocated down to a cost centre nearer to the level of the individual output. The head office costs get spread amongst the production lines; the production line costs get spread amongst the units produced on that line. Eventually, all the costs can be allocated to a particular unit of output.
Another approach, called activity-based costing (ABC), can be better. With ABC, the fundamental cost object is not a unit of product but an organizational activity, such as an event, task or unit of work. The costs of these activities are then used to allocate costs to products, customers, or services.
[S]ix aspects of budgeting: planning, motivation, delegation, communication/coordination, control, and performance evaluation.
Without the budgeting process, managers might just carry on with their routine tasks, and then engage in crisis management. By getting managers to think ahead, they foresee problems and are in a better position to prevent them arising.
[T]here are various aspects of staff behaviour that should be considered. For example, if any unspent part of a travel cost budget is taken away at the end of each year, staff will be tempted to make unnecessary journeys near the end of the year because they like travel or because they fear that next year’s budget will be reduced if the present one is underspent.
[A]n organization […] might forget to ask whether particular activities are really needed or whether certain activities could be done more cheaply or done completely differently. Consequently, there is a good argument for demanding that managers should start from scratch each year, with ‘zero-base budgeting’.
Once the accountants have calculated the variance, they need to consider whether the variance is favourable (F) to the firm, or unfavourable (U). Some companies use the word ‘adverse’ (A) instead of unfavourable.
Quis custodiet ipsos custodes?
There are two main high-level purposes of budgeting. The first is to optimize the use of the economic resources within the firm in order to maximize profit. […] The second purpose is to help the firm to achieve its overall strategic objectives.
Any differences between budgeted and actual figures are called variances and this method of comparison is called ‘variance analysis’, […] Managers need to investigate the differences (variances) and to identify the causes. These might include the original estimates being poorly thought out and incorrectly calculated; or possible overspending on materials.
