问题如下：
1. Using the economic balance sheet approach, the Laws’ economic net worth is closest to:
选项：
A.$925,000.
B.$1,425,000.
C.$1,675,000.
解释：
A is correct.
The Laws’ economic net worth is closest to $925,000. An economic balance sheet includes conventional financial assets and liabilities, as well as extended portfolio assets and liabilities that are relevant in making asset allocation decisions. The economic balance sheet for the Law family is shown in the following exhibit.
Economic net worth is equal to total economic assets minus total economic liabilities
($2,675,000 – $1,750,000 = $925,000).
请问这道题，之前记的笔记是Economic Net Worth=Financial Asset-Financial Liability Only, 而Economic Net Wealth才是含Extended Wealth的？
是我的笔记记错了吗，这个知识点具体在讲义哪里呢也没有找到。
求解答。
