Conservatism

Choosing the accounting treatment that is least likely to overstate assets or income or understate liabilities or expenses.

It is believed that following this principle will ultimately lead to bias in the financial statements and to overstating financial performance in later periods. Accounting statements are supposed to be neutral, free from bias, so most CPAs no longer adhere to this principle.
