问题 问答题

某房地产开发公司对某一地块有两种开发方案。

A方案:一次性开发多层住宅45000m2建筑面积,需投入总成本费用(包括前期开发成本、施工建造成本和销售成本,下同)9000万元,开发时间(包括建造、销售时间,下同)为18个月。

B方案:将该地块分成东、西两区分两期开发。一期在东区先开发高层住宅36000m2建筑面积,需投入总成本费用8100万元,开发时间为15个月。二期开发时,如果一期销路好,且预计二期销售率可达100%(售价和销量同一期),则在西区继续投入总成本费用8100万元开发高层住宅36000m2建筑面积;如果一期销路差,或暂停开发,或在西区改为开发多层住宅22000m2建筑面积,需投入总成本费用4600万元,开发时间为15个月。

两方案销路好和销路差时的售价和销量情况汇总于表2-1。

根据经验,多层住宅销路好的概率为0.7,高层住宅销路好的概率为0.6。暂停开发每季损失10万元。季利率为2%,见表2-2。

问题:

试决定采用哪个方案。

(注:计算结果保留两位小数。)

答案

参考答案:

方案判定。

(1) 机会点①。

净现值的期望值:(3600×0.7+2580×0.3)×(P/A,2%,6)-9000 =(3600×0.7+2580×0.3)×5.601-9000 =9449.69万元

(2) 机会点②。

净现值的期望值: [10563.48×(P/F,2%,5)+3960×(P/A,2%,5)]×0.6+[4507.78×(P/F,2%, 5)+2520×(P/A,2%,5)]×0.4-8100 =(10563.48×0.906+3960×4.713)×0.6+4507.78×0.906+2520×4.713)×0.4-8100 =16940.40+6384.32-8100 =15224.72万元 1707.38万元

(3) 机会点③。

净现值的期望值:3960×(P/A,2%,5)×1.0-8100=3960×4.713×1.0-8100=10563.48万元

2241.35万元

(4) 机会点④。

净现值的期望值:-10×(P/A,2%,5)=-10×4.713=-47.13万元

万元

(5) 机会点⑤。

净现值的期望值:(2112×0.7+1513.6×0.3)×(P/A,2%,5)-4600=(2112×0.7+ 1513.6×0.3)×4.713-4600=4507.78万元

根据计算结果判断,B方案在一期开发高层住宅销路差的情况下,二期应改为开发多层住宅。 根据计算结果,应采用B方案,即一期先开发高层住宅,在销路好的情况下,二期继续开发高层住宅;在销路差的情况下,二期改为开发多层住宅。

She had been shopping with her Mom in Wal­Mart. She must have been 6 years old. It was 31 outside. We all stood just 32 the door of the Wal­Mart.
Her voice was so sweet for the 33 waiting.“Mom, let’s run through the rain,” she said.
“What?” Mom asked.
“Let’s run through the rain!” She 34 .
“No, honey. We’ll wait until it 35 down a bit,” Mom replied.
This young child waited about 36 minute and repeated,“Mom, let’s run through the rain.”
“We’ll get soaked if we do,” Mom said.
“No,we won’t, Mom. That’s not what you said this morning,” the young girl said as she 
 37 her Mom’s arm.
“This morning?When did I say we could run through the rain and not get 38 ?”
“Don’t you remember?When you were talking to Daddy about his cancer, you said,‘If God can get us 39 this, he can get us through anything!’”
The entire crowd became dead silent. I  40 you couldn’t hear anything but the rain. We all stood silently. Mom  41 and thought for a moment about what she would say.
“Honey, you are absolutely right. Let’s run through the rain. If we get wet, maybe we just need  42 ,” Mom said. Then off they ran.
We all stood watching, smiling and laughing as they  43 past the cars. They held their shopping  44 over their heads just in case. They got soaked. But they were  45 by a few who screamed and laughed like children all the  46 to their cars. And yes, I did. I ran. I got wet. I needed washing. Circumstances or people can take away your  47 possessions, they can take away your money, and they can take away your   48 .But no one can ever take away your precious  49 . So, don’t forget to  50 time and take the opportunities to make memories every day!
