选项：
A. $11.85 million.
B. $12.75 million.
C. $12.87 million.
解释：
B is correct.
Total fees paid to all funds (underlying funds and Ash Lawn) are $12.75 million, consisting of underlying fund fees of $9.26 million and Ash Lawn fees of $3.49 million, calculated as follows:
Underlying fund fees:
Management fee = $133 million × 0.02 = $2.66 million.
Incentive fee = ($133 – $100) million × 0.20 = $6.60 million.
Total underlying fund fees ($2.66 + $6.60) million = $9.26 million.
Ash Lawn fees:
AUM at end of year, net of underlying fund fees = $133 million – $9.26 million = $123.74 million.
Ash Lawn management fee = $123.74 million × 0.01 = $1.24 million (rounded).
AUM net of underlying fund fees and Ash Lawn management fee = ($123.74 – $1.24) million = $122.50 million(rounded).
Ash Lawn incentive fee = ($122.50 – $100) million × 0.10 = $2.25 million (rounded).
Total Ash Lawn fees = ($1.24 + $2.25) million = $3.49 million (rounded).
Total fees of underlying funds and Ash Lawn:
($9.26 + $3.49) million = $12.75 million (rounded).
计算FoF总费用就要分别计算两层基金的费用：
底层基金管理费=年底AUM*对应管理费率=$133 million × 0.02 = $2.66 million
绩效奖是单独计算的，因此直接在年底AUM基础上计算绩效奖=($133 – $100) million × 0.20 = $6.60 million
所以底层总的费用=($2.66 + $6.60) million = $9.26 million。
对于母基金来说，扣除完底层总费用后的年底AUM净值=$133 million – $9.26 million = $123.74 million
所以母基金管理费=$123.74 million × 0.01 = $1.24 million
母基金的绩效奖是按扣除完管理费净额计算=($123.74 – $1.24 - $100) *0.1=2.25million
所以母基金总费用=($1.24 + $2.25) million = $3.49 million
所以两层基金的总费用=($9.26 + $3.49) million = $12.75 million
133是母基金获得的？还是底层基金？
