Financial Accounting I is specially designed as an undergraduate textbook for the first year B Com (Hons and Gen.) students of University of Calcutta (CU). The book seeks to provide a comprehensive coverage of the basic principles of financial accounting, incorporating the latest accounting norms and standards. The book begins with an introduction to accounting, double-entry book-keeping system, basis of accounting, and basic concepts and conventions of accounting. It moves on to accounting theory and accounting standards, followed by the concepts of revenue recognition, inventories, depreciation, reserves and provisions, provisions on debtors and creditors, capital and revenue transactions, adjustment entries, and rectification of errors. It then delves deep into the concept of preparing final accounts including final accounts of sole proprietorship trading concerns, of manufacturing concerns, from incomplete records, and of non-profit organizations. It then proceeds to describe the concepts of accounting for consignment, and for sales on approval basis, self-balancing and sectional balancing system, and insurance claims for loss of stock and loss of profit. Written in a crisp and easy-to-understand style, the book also incorporates a large number of worked-out problems, solutions to relevant problems set by CU B Com (Hons & Gen.) and professional examinations such as CA, CS, and CWA, thereby making it ideal for self-study.
