An audio commentary is an additional audio track, usually digital, consisting of a lecture or comments by one or more speakers, that plays in real time with a video. Commentaries can be serious or entertaining in nature, and can add information which otherwise would not be disclosed to audience members.[1]
In accounting terms, operating expenses, or OE, and cost of goods sold, or COGS, are both considered expense accounts. In short, they measure different ways in which resources are spent in the process of running a business.
For example, inventory is an asset. Expenses are the cost of bringing in revenues. They were needed to bring in the revenues and profits that you reported this year. Expenses appear on the income statement. For example, just as inventory is an asset, âcost of goods soldâ is an expense. This is the cost of inventory that was sold during the year. The difference is really one of timing. An asset is expected to bring in a benefit sometime in the future. When the benefit comes in, then the asset becomes an expense. As it is sold, inventory is moved out of the inventory account on the balance sheet, and into the cost of goods sold account on the balance sheet.
