FFO，AFFO的完整公式能给一下吗？

问题如下：

 Method 1 Net asset value

 Method 2 Discounted cash flow valuation using a two-step dividend model

 Method 3 Relative valuation using property subsector average P/FFO multiple

 Method 4 Relative valuation using property subsector average P/AFFO multiple

Based upon Exhibits 1 and 2, the value per share of REIT A using valuation Method 4 is closest to:

选项：

A.$58.32. B.$74.12. C.$103.40.

解释：

The value per share is $74.11, calculated as:

Funds from operations (FFO) = $316,965

Less: Non-cash rents: $25,991

Less: Recurring maintenance-type capital expenditures: $63,769

Equals: AFFO: $227,205

Shares outstanding = 56,100 shares

AFFO/share = $227,205/56,100 shares = $4.05.

Applying the property subsector average P/AFFO multiple of 18.3x yields a value per share of:$4.05 × 18.3 = $74.12.
