Some liabilities are not contingent liabilities but are estimated liabilities. For example, the electricity consumed, property taxes, worker compensation insurance premiums, repairs, etc. are absolutely owed because the services or goods were delivered. There is nothing contingent about these. However, the precise amounts may not be known at the time that the financial statements are prepared. Therefore, these liabilities had to be recorded by using estimated amounts. I suspect that many of the accrual-type adjusting entries involve estimated liabilities.
