Some of the significant updates and new material include: Discussion of the significance of shale and unconventional production as it relates to accounting principles. New definitions of reserves from the Securities and Exchange Commission, and the impact on accounting processes. All citations and references align with the updated authoritative literature from the Financial Accounting Standards Board. A new chapter discussing specific issues previously unaddressed regarding property valuation in the industry. New, and updated, end-of-chapter problems.
