Essentials of Corporate Finance, 4/e by Ross, Westerfield, and Jordan is written to convey the most important concepts and principles of corporate finance at a level that is approachable for a wide audience. The authors retain their modern approach to finance, but have distilled the subject down to the essential topics in 18 chapters. They believe that understanding the "why" is just as important, if not more so, than understanding the "how," especially in an introductory course. Three basic themes emerge as their central focus:1. An emphasis on intuitionżseparate and explain the principles at work on a common sense, intuitive level before launching into specifics. Underlying ideas are discussed first in general terms, then followed by specific examples that illustrate in more concrete terms how a financial manager might proceed in a given situation2. A unified valuation approachżNet Present Value is treated as the basic concept underlying corporate finance. Every subject the authors cover is firmly rooted in valuation, and care is taken to explain how decisions have valuation effects.3. A managerial focusżStudents learn that financial management concerns management. The role of financial manager as decision maker is emphasized and they stress the need for managerial input and judgment.
