The matching principle is a core accounting concept that dictates that expenses should be recognized in the same period as the revenues they help to generate. By matching revenues and costs, the financial statements provide a more accurate representation of the company's profitability during a specific reporting period.

Terminal bonuses are designed to reward policyholders for maintaining their policies over a long period. Consequently, the amount of the terminal bonus is directly correlated with the duration of the policy; the longer the policy remains in force, the higher the accumulated terminal bonus tends to be.

Accounting conventions are customs or traditions used as a guide in preparing financial statements. Consistency, full disclosure, and materiality are widely recognized accounting conventions. Secrecy is not an accounting convention; in fact, accounting principles emphasize transparency and the disclosure of relevant financial information to stakeholders rather than maintaining secrecy.

Accounting principles are the fundamental rules that guide financial reporting. They are broadly divided into accounting concepts, which are the basic assumptions or postulates underlying the accounting process, and accounting conventions, which are the customs or traditions adopted as a guide in the preparation of financial statements.

Accounting principles are developed to ensure that financial reporting is useful, consistent, and reliable. Practicability is a core criterion because accounting standards must be implementable in real-world business environments. If a principle is theoretically sound but impossible to apply efficiently, it fails the test of utility. Therefore, accounting standards are designed to balance theoretical accuracy with the practical requirements of business operations and financial reporting.

Revenue is recognized when the performance obligation is satisfied, which typically occurs when the sale is effected (i.e., ownership and risk are transferred to the buyer). It is not dependent on the actual receipt of cash, which relates to the cash basis of accounting.

Accounting policies are selected based on principles such as Prudence, Substance over form, and Materiality. 'Accountancy' is a broad field of study or practice rather than a specific accounting principle or convention used to guide the selection of accounting policies in financial reporting.

The matching concept requires that expenses incurred to generate revenue must be recognized in the same accounting period as the revenue itself. This ensures that the profit or loss for a specific period is accurately determined by matching costs against the related income.

Tangible assets are physical assets that have a material existence and are used in the production or supply of goods and services. Land, buildings, and machinery are classic examples of property, plant, and equipment (PP&E), which are long-term, non-current assets that provide economic benefits to the company over multiple accounting periods.

Bookkeeping is the foundational aspect of accounting that focuses on the systematic recording of financial transactions. It involves maintaining daily records, such as journal entries and ledger postings, to ensure all business operations are documented. While accounting involves the broader scope of summarizing, interpreting, and analyzing data, bookkeeping is strictly limited to the initial record-keeping phase of the financial cycle.
