This document discusses key accounting concepts including fiscal versus calendar years, cash versus accrual accounting, adjusting entries, correcting entries, qualities of financial information, closing entries, and the accounting cycle. It provides definitions and examples of these concepts. Fiscal year refers to an accounting time period that is one year in length, while a calendar year runs from January 1 to December 31. Accrual accounting records transactions when events occur rather than when cash is received or paid. Adjusting entries ensure revenues and expenses are recorded in the proper periods according to accounting principles. Correcting entries fix posting errors. Closing entries transfer balances to prepare for a new accounting period.
