Imagine you are a sell-sider and you have 18 companies in your coverage universe. To review 18 annual reports would be incredibly time consuming. You can score huge points with a nice email summary of highlights (i.e. new items, items taken out, subsequent events, etc.). Here is an example.
The objective of this resource is to give your sell-side community a listing of highlights within your 10-K to make it easy for them to find information. You can include a disclaimer in the first para that it is not intended to be every change. But, it should be the material changes. We promise this communication will be appreciated.
