Alright, so a great internal control over cash is the use of bank reconciliation. This is where the company takes the monthly bank statement that they receive from the bank and checks it against the company's records to ensure that everything is okay between the two.
Cash is the most liquid asset, right? When we talk about liquidity, liquidity is how quickly it can be converted to cash. Well, cash is already cash, so it's extremely liquid and easy to steal, right? Anyone who gets their hands on the cash might have an incentive to actually steal it. So, we're going to need specific internal controls over cash, and one is the bank reconciliation. Like I said, this is where we compare the bank statement that we get every month to the company records.
What we're going to notice is that the bank statement is generally not going to be the same as what we see in our company records, and this difference is due to a time lag. Think about it: for a company that's constantly receiving money from customers, buying stuff, having all sorts of expenses, there's all sorts of activity in the account. If we were to stop at a certain point in time, there would still be things that hadn't been processed on either end.
For instance, back in the day, you might receive a check on payday and it wouldn't clear immediately. You'd have to go to the bank, deposit it, and then wait for it to clear. There's this time lag. You might have recorded something in your books that the bank hasn't recorded yet, or the bank might have recorded something that you didn't know about until you got the monthly bank statement. Let's see how this bank reconciliation works.
The goal of the bank reconciliation is to get to an adjusted balance. We're going to have a number from the bank that represents the amount of cash in our bank account as of that date, and we'll have our accounting records that show us some amount as well, and we're going to adjust those numbers for different items to end up at the same number in both accounts.
Let's start with the bank column of the reconciliation. This is when there are events recorded by the company but not yet by the bank. For example, first, we have deposits in transit. This is where the company has received a check. Think about it: the customer had mailed a check to the company, the company received the check and they're like "Sweet, we got this money" and they made an entry. They received cash, credit accounts receivable. They got money from a customer and then they go deposit it in the bank, but the bank hasn't cleared the check yet. So, we need to add the deposits in transit to the bank side of the reconciliation because we recorded it in our books, but the bank has not recorded it yet.
The opposite situation is an outstanding check. This is where we receive an invoice from a supplier, and we write a check. So, we write a check to say, "Okay, we're going to pay the supplier," so we wrote that check and made a journal entry to decrease our cash because we were going to pay cash to our supplier. But at this point in time, that check hasn't cleared yet; maybe the supplier hasn't deposited it in their account yet, or maybe the bank is still waiting to clear it. For whatever reason, the bank balance does not show that we paid this check yet. So we need to subtract this amount from the bank balance to ensure that we get to the correct adjusted balance.
And the last one for banks, well, those are the two big ones: deposits in transit and outstanding checks. You're pretty much always going to see these when you do a bank reconciliation. They're always on the bank side of the reconciliation. There's nothing that's going to be done on the book side for those. The last category here is bank errors; banks sometimes just love to make errors especially in accounting problems. So, when an error occurs, we need to remove its effects. Unfortunately, this could be anything, often something like confusing the numbers, for example, they were supposed to make a $150 payment, but they made a $510 payment instead.
That's the bank side of the reconciliation. Let's pause, and then we'll go over the book side of the reconciliation.
