I need to do presentation of summary in the document attached. But Its hard to organize my thought on main points and not sure if im even understanding it correctly. Is there anyone who can help me summarize this by main points and to prepare for presentation?

Below is the document that Im doing an presentation 

https://docplayer.net/1397800-Court-awards-of-damages-for-loss-of-future-earnings-an-empirical-study-and-an-alternative-method-of-calculation.html

Im doing presentation explaining by each sections so, I am hoping to have main points summerized by each sections. For instance,

1. INTRODUCTION

2. THE METHOD USED BY THE COURTS TO ASSESS DAMAGES FOR LOSS OF FUTURE EARNINGS IN ENGLAND AND WALES

3. THE ASSESSMENT OF LOSS OF FUTURE EARNING IN THE UNITED STATES OF AMERICA

1. Wage Growth

2. Expected Working Life

4. AN ALTERNATIVE METHOD OF CALCULATION

5. A CASE STUDY APPLICATION OF THE ALTERNATIVE METHODOLOGY

I would need to address important aspects of each section and explain what it means. 

Thank you!
