Theory Base of Accounting Class 11 Financial Accounting 1 Notes

Generally Accepted Accounting Principles (GAAP)

To ensure that accounting information is useful, reliable, and comparable for everyone who uses it—from owners and managers to investors and banks—it's crucial to have a set of common rules. Imagine trying to compare two companies if each one recorded its finances in a completely different way; it would be impossible to tell which one was performing better. This is why a proper theory base for accounting is so important.

This theory base is built on what we call Generally Accepted Accounting Principles (GAAP). Think of GAAP as the grammar of accounting. It's a collection of rules, guidelines, concepts, and conventions developed over time that the accounting profession agrees upon. These principles bring uniformity and consistency to how business transactions are recorded and presented in financial statements.

These principles have evolved from past experiences, customs, and statements by professional bodies like the Institute of Chartered Accountants of India (ICAI). While they provide a stable foundation, they are not static; they change over time to adapt to new legal, social, and economic environments.

You might hear these rules called by different names like 'concepts', 'conventions', or 'assumptions'. In practice, these terms are often used interchangeably. For our purposes, we will refer to them as Basic Accounting Concepts.

Basic Accounting Concepts

Basic accounting concepts are the fundamental ideas or assumptions that guide all accounting activities. They are the broad working rules that ensure financial accounting is practiced correctly and consistently.

The most important concepts are:

Business entity
Money measurement
Going concern
Accounting period
Cost
Dual aspect (or Duality)
Revenue recognition (Realisation)
Matching
Full disclosure
Consistency
Conservatism (Prudence)
Materiality
Objectivity

Business Entity Concept

This concept states that a business is a separate and distinct entity from its owners. For accounting purposes, the business and its owner are treated as two different entities.

This is a very important idea. When an owner invests money (capital) into their business, the accounting records show this as a liability for the business. Why? Because the business (one entity) now owes that money back to the owner (a separate entity).

Example

If an owner invests ₹10,00,000 as capital, the business's books will show an increase in cash (an asset) and an increase in capital (a liability to the owner). Similarly, if the owner withdraws money for personal expenses (drawings), it's treated as a reduction of the owner's capital, decreasing the business's liability.

This separation means that the owner's personal assets, liabilities, and transactions are not mixed with the business's records unless the transaction involves an inflow or outflow of business funds.

Money Measurement Concept

The Money Measurement Concept says that only transactions that can be expressed in terms of money are recorded in the accounting books. Events or qualities that cannot be measured in monetary terms are not recorded, no matter how important they are.

For example, things like the skill of a manager, the creativity of a research team, or the company's public image are not recorded in financial statements because you can't assign a specific monetary value to them.

Furthermore, all records are kept in a monetary unit (like rupees), not in physical units.

Example

A business might have 2 acres of land, 10 office rooms, 30 computers, and 20 tons of raw material. You can't add these different units together. For accounting, each item is converted to its monetary value (e.g., land worth ₹2 crore, computers worth ₹15 lakh) so they can be added up to find the total worth of the business's assets.

A key limitation of this concept is that it ignores changes in the value of money over time due to inflation. A building bought for ₹2 crore in 1995 is still recorded at that price, even though its real value today might be much higher. This means the accounting data may not always show the true and fair view of the business.

Going Concern Concept

This concept assumes that a business will continue its operations for a long time into the future and will not be shut down or liquidated. This is a fundamental assumption that allows us to properly value assets.

An asset, like a computer, is essentially a bundle of future services. If you buy a computer for ₹50,000 with an expected life of five years, the Going Concern Concept allows you to spread its cost over those five years.

Example

Instead of treating the entire ₹50,000 as an expense in the year of purchase, you can charge ₹10,000 as an expense each year for five years. This is because the business is expected to 'go on' and benefit from the computer for its entire life. The remaining value is carried forward as an asset. Without this assumption, you would have to expense the full cost immediately, which wouldn't accurately reflect the year's profit.

Accounting Period Concept

While a business is assumed to have an indefinite life (Going Concern), its stakeholders need to know its financial performance at regular intervals. The Accounting Period Concept addresses this need by dividing the life of the business into shorter time spans, called accounting periods.

Financial statements are prepared at the end of each period to determine the profit or loss and the financial position (assets and liabilities). This allows users to make timely decisions.

Typically, an accounting period is one year. In India, both the Companies Act and the Income Tax Act require annual statements. However, sometimes interim statements are needed, such as when a partner retires or for companies listed on the stock exchange, which must publish quarterly results.

Cost Concept

The Cost Concept (also known as the historical cost concept) requires that all assets are recorded in the books of accounts at their original purchase price. This price includes not just the cost of acquisition but also all expenses incurred to make the asset ready for use, such as transportation, installation, and repairs.

Example

If a company buys a plant for ₹50 lakh and spends ₹10,000 on transport, ₹15,000 on repairs, and ₹25,000 on installation, the total cost recorded for the plant in the accounting books would be ₹50,50,000.

This cost is historical—it's what was paid at the time of purchase and does not change, even if the market value of the asset goes up or down. This brings objectivity to accounting because the purchase price can be verified from documents. However, a limitation is that it may not reflect the true current worth of the business's assets.

Dual Aspect Concept

This is the foundation of modern accounting. The Dual Aspect Concept states that every business transaction has a two-fold effect and is recorded in at least two places. For every benefit received (a debit), there is a benefit given (a credit).

This principle is the core of the Double Entry System of accounting and is expressed through the fundamental Accounting Equation:

Note

Assets = Liabilities + Capital

This equation means that the total assets of a business are always equal to the total claims against those assets. These claims come from two sources: outsiders (Liabilities) and owners (Capital or Owner's Equity).

Example

Ram starts a business with ₹50,00,000. The business's cash (Asset) increases by ₹50,00,000, and its Capital (Liability to the owner) also increases by ₹50,00,000. The equation remains balanced.
The business buys goods for ₹10,00,000 cash. One asset (stock of goods) increases by ₹10,00,000, while another asset (cash) decreases by the same amount. The equation remains balanced.
The business buys a machine for ₹30,00,000 on credit. An asset (machinery) increases by ₹30,00,000, and a liability (creditor) also increases by ₹30,00,000. The equation remains balanced.

Revenue Recognition (Realisation) Concept

This concept dictates when revenue should be recorded in the accounting books. Revenue is the inflow of cash from the sale of goods/services or from others using the enterprise's resources (e.g., interest, rent).

The rule is that revenue is recognized (or "realised") when the legal right to receive it arises, not necessarily when the cash is actually received. For sales, this is usually the point when goods have been sold or services have been rendered.

Example

If goods are sold on credit in March 2017, the revenue is recorded for the financial year ending March 31, 2017, even if the payment is received in April 2017. Similarly, rent for March, even if received in April, is considered revenue for March.

There are exceptions, such as in long-term construction projects where revenue may be recognized proportionally as the work is completed.

Matching Concept

To accurately calculate the profit or loss for a period, the expenses incurred during that period must be "matched" with the revenues earned during the same period. This is the essence of the Matching Concept.

This means that revenues and the expenses incurred to generate those revenues must belong to the same accounting period.

Example

To calculate profit for a year, you must deduct expenses like salaries, rent, and insurance that relate to that year, regardless of whether they were actually paid during that year. For the cost of goods sold, you only consider the cost of the goods that were actually sold during the year, not the cost of all goods purchased or produced. The cost of unsold goods is carried forward to the next period.

This concept works hand-in-hand with the accrual basis of accounting.

Full Disclosure Concept

Since financial statements are the primary way to communicate information to users like investors and lenders, the Full Disclosure Concept requires that all material and relevant facts about a company's financial performance and position must be completely disclosed.

This information is presented in the financial statements themselves or in the accompanying footnotes. The goal is to provide users with enough information to make informed decisions and a correct assessment of the firm's profitability and financial health. To ensure this, laws like the Indian Companies Act and regulatory bodies like SEBI mandate specific formats and disclosures for companies.

Consistency Concept

For accounting information to be useful, it must be comparable—both over different periods for the same company (inter-period) and between different companies in the same industry (inter-firm). The Consistency Concept makes this possible by stating that the accounting policies and practices followed by an enterprise should be uniform and consistent from one period to another.

Example

If a company uses a specific method for calculating depreciation or valuing stock, it should use the same method every year. If it changes the method, the profit figures for different years would not be comparable. Any change in policy must be fully disclosed, along with its likely effect on the financial results.

Conservatism Concept (Prudence)

The Conservatism Concept, also known as prudence, is a policy of "playing safe." It guides accountants to be cautious and not overstate profits or assets. The principle is: "Do not anticipate profits, but provide for all possible losses."

This means that profits should only be recorded when they are actually realised, but all losses, even those with a remote possibility, should be accounted for.

Example

Valuing closing stock at its cost price or market value, whichever is lower. If the market value has fallen, the loss is recognized. If it has risen, the gain is ignored until the stock is sold.
Creating a provision for doubtful debts to account for customers who may not pay.

This approach protects creditors and ensures that dividends are not paid out of capital. However, it should not be used to deliberately underestimate assets and create "secret reserves."

Materiality Concept

The Materiality Concept states that accounting should focus on material facts. An item is considered material if its knowledge would influence the decision of an informed user of the financial statements. Efforts should not be wasted recording facts that are immaterial or insignificant.

What is material depends on the nature of the item and the amount involved.

Example

Money spent on building a new wing for a theatre is a material fact because it will increase future earnings and should be disclosed. However, the cost of small stationery items like pencils and erasers is usually treated as an expense for the period in which they are bought, even if they are not fully consumed. The amount is so small that treating the remaining stock as an asset is not worth the effort and would not affect users' decisions.

Objectivity Concept

The Objectivity Concept requires that accounting transactions be recorded in an objective manner, free from the personal bias of accountants or management.

This is achieved by ensuring that every transaction is supported by a verifiable document or voucher.

Example

A cash purchase is supported by a cash receipt. A credit purchase is supported by an invoice and delivery challan. The purchase of a machine is verified by the payment receipt, which provides an objective basis for its historical cost. This is one of the main reasons the Cost Concept is used—the purchase price is verifiable, whereas the market value can be subjective and vary from person to person.

Systems of Accounting

There are two main systems for recording business transactions:

Double Entry System: This system is based on the Dual Aspect Concept. It recognizes that every transaction has two effects: a receiving aspect (debit) and a giving aspect (credit). Every transaction affects at least two accounts, and for every debit, there is a corresponding credit. This is a complete, accurate, and reliable system that helps minimize fraud and allows for checking arithmetic accuracy through a trial balance. It can be used by both large and small organizations.
Single Entry System: This is not a complete system. It does not record the two-fold effect of every transaction. Typically, only personal accounts and a cash book are maintained. Because it is incomplete and unsystematic, it is not considered reliable. However, its simplicity makes it popular with very small businesses.

Basis of Accounting

This refers to the timing of when revenues and costs are recognized in the accounts. There are two main bases:

Cash Basis: Under this system, transactions are recorded only when cash is actually received or paid. Revenue is recorded when payment is received from a customer, and expenses are recorded when they are paid. This method does not follow the matching principle and is generally considered inappropriate for most organizations because it doesn't accurately reflect the profit earned during a period.

Example

If office rent for December 2014 is paid in January 2015, under the cash basis, it is recorded as an expense of January 2015, not December 2014.

Accrual Basis: Under this system, revenues and costs are recognized in the period in which they occur, regardless of when cash is received or paid. Revenue is recorded when it is earned (e.g., when a sale is made), and expenses are recorded when they are incurred (e.g., when a service is used). This is a more appropriate basis for calculating profit as it adheres to the matching principle.

Example

Using the same rent example, under the accrual basis, the rent for December 2014 is recorded as an expense of December 2014, even though it was paid in January 2015.

Accounting Standards

Accounting Standards are written policy documents issued by professional bodies like the ICAI in India. They cover aspects of recognition, measurement, presentation, and disclosure of accounting transactions in financial statements.

The main objective of accounting standards is to bring uniformity to accounting policies and eliminate non-comparability of financial statements, thereby enhancing their reliability.

Benefits of Accounting Standards

They help eliminate variations in accounting treatments used by different businesses.
They may require disclosures of useful information not otherwise required by law.
They make it easier to compare the financial statements of different companies (inter-company) and of the same company over different periods (intra-company).

Limitations of Accounting Standards

They can be rigid and reduce flexibility by limiting the choice between different alternative treatments.
They cannot override laws or statutes. Standards must be framed within the boundaries of existing laws.

Goods and Services Tax (GST)

Goods and Services Tax (GST) is a comprehensive, destination-based tax levied on the consumption of goods and services. It is collected at every stage from manufacturing to final consumption, with credit available for taxes paid at previous stages. This means that only the "value addition" at each stage is taxed, and the final burden is borne by the end consumer.

GST in India has a dual structure to align with the country's federal system, where both the Centre and the States have powers to levy taxes. The main components are:

CGST (Central Goods and Services Tax): This is levied by the Central Government on intra-state (within the same state) transactions. The revenue goes to the Centre.
SGST (State Goods and Services Tax): This is levied by the State Government on intra-state transactions. The revenue goes to the respective state.

Example

If a dealer in Punjab sells goods worth ₹10,000 to another person in Punjab, and the GST rate is 18% (9% CGST + 9% SGST), then ₹900 goes to the Central Government (as CGST) and ₹900 goes to the Punjab Government (as SGST).

IGST (Integrated Goods and Services Tax): This is levied by the Central Government on inter-state (from one state to another) transactions and on imports. The revenue is then divided between the Centre and the destination state.

Example

If a dealer in Madhya Pradesh sells goods worth ₹1,00,000 to a dealer in Rajasthan, and the GST rate is 18%, the seller will charge ₹18,000 as IGST, which will go to the Central Government.

Characteristics of GST

It is a common law and procedure throughout the country.
It is a destination-based tax, meaning tax accrues to the state where consumption happens.
It is a comprehensive tax on both goods and services at the same rate.
It has eliminated multiple taxes like sales tax, entry tax, entertainment tax, etc.

Advantages of GST

Abolition of multiple types of taxes.
Increased revenue for the government and reduced administrative costs.
Reduced compliance costs for businesses.
Removal of the cascading effect (tax on tax).
Potential to increase manufacturing, economic efficiency, and exports.
