Combined Statement
  
Like when all the bankrupt countries of the world get together and decry, "We can't pay our bills!" That's a combined statement.
Ok ok. It's really a simplified look at your banking activity. A bank can provide a combined statement of all your financial transactions...all deposits, all withdrawals, all checks received or sent, any interest earned, etc.
The combined statement includes all accounts. For individuals, this might consist of a checking and a savings account. It can also include things like mortgage details or retirement savings accounts, if those are processed through the same bank.
Companies tend to have a more complicated network of accounts than individuals. They use these for various activities (payroll, checking, credit card receivables, etc.). The combined statement is very useful in these cases, providing a consolidated view of financial transactions, useful for producing P/L statements or for preparing taxes.
