Nowadays organizations and funds use two or even more formats for their annual reports. For instance, you can send a postcard with essential report information to all stakeholders and partners, offering them the opportunity to go online to learn more thoroughly about your content on a mini-site or to go and watch the video.
If you create a traditional thick printed report, you can consider sending it only to selected key persons. Then make it available in a user-friendly digital publication version for others. You can email it to the people you want to target, and thereby make an emphasis on the value of your report.
