 So cost variances, cost variances, the difference between the actual and standard costs. So remember, whenever you see this word variance, it's going to basically mean the difference. And whenever we consider the difference, we're typically comparing what actually happened to what we budgeted to happen. When we're talking about variance analysis, the thing that we predicted to happen kind like what we budgeted in essence, the predictions that we had are going to be the standards. So remember, if you see standard, that's going to be what we expected to happen, what we had calculated and estimated that would happen, what we think should happen. And then the actual cost, anytime you see actual, that's what actually did happen. So you got to put your mindset and say, hmm, this is the standard. That's what we must have come up with before the time period had passed. And anytime you see actual, you got to say, ah, well now the time period must be over and we have the actual numbers and we can compare what we had thought would happen back way back when, before the time period had passed to the time period that had passed and figure out those difference. That's typically the way you want to kind of consider what would happen. The standards, I mean, we could think of the standards as we're going to make the standard what we think should have happened at this point in time, at the same point in time, but it's easier to think of the standards as a similar to a budgeting process. This is what we think should happen. Then here's what the time period has passed and then figure out anytime we have the actual versus the standard, what those differences will be.
