Cost accounting is a dynamic discipline that is constantly responding to the needs of man-agers in a highly competitive and global business world. While the primary use of cost accounting is to determine product costs for internal management and external financial reporting, managers also need cost accounting information to develop, implement, and evaluate strategy. The ninth edition of Cost Accounting Principles covers the fundamental cost accounting procedures and calculations as well as the more strategic cost management concepts needed for planning and decision making. A text is valuable only when students find the subject matter applicable to their busi-ness or personal lives. Through the use of a straightforward, readable approach, Cost Accounting Principles engages students by highlighting the real-world relevance of each topic. The text encourages students to expand their capabilities beyond merely computing answers to critically thinking about a variety of business issues.
