2 Despite different home cultures and countries, international students' main overall motivation is the desire get out on their own, to carve out a new direction in their lives. "Foreign students" do not casually abandon the comforts of family and cultural ties; they have done their homework on Canadian schools. All their preparation, though, cannot prepare them for the loneliness and ongoing difficul- ties they face, from cold winters to financial issues related to the higher tuition fees they must pay. Some students, though, emigrate to escape those same tight- knit families and bonds that others find so painful to leave behind. A Macleans "On Campus" report notes that family expectations may be opposed to students' visions for themselves and lead them to reject accepted values and career paths in their hometowns and countries. Csilla, a web-design student at Waterloo admits, "I was always supposed to enter my family's restaurant business in Budapest, but I felt suf- focated even working part-time as a server. Web design is my passion, and I wanted 12: CAUSE OR EFFECT [- a completely fresh start, something that is completely my own ("International Stu- dents"). Finding independent paths to their own dreams is the key here, whether students choose those paths as a result of personal ideals or as a reaction to pre-set future plans.

Jenkins Resources Inc. has the following capital structure: Proportion of Capital Structure 27% Financing Source Debentures (9% coupon, $1,000 par value, 12 year maturity) Preferred stock ($2 dividend, $25 par value) Common equity Total 8 65 100% a Jenkins expects to raise future capital in the proportions currently indicated on the balance sheet. The current market price for Jenkins debentures is $1,075. If new debentures were sold, the issuance cost would be $20 per bond. The current market price for the preferred stock is $19. Issuance costs on new preferred stock would be $1 per share for a $25 par value issue. Issuance costs on new equity would be $2.50 per share. The current market price for Jenkins common stock is $40. The stock pays a current (Do) dividend of $3. This dividend is expected to grow at an annual rate of 7 percent. What is the weighted (marginal) cost of capital for Jenkins Resources, assuming new capital is raised in the proportions shown here and that all new equity comes from the sale of new shares, new debt comes from the sale of debentures, and new preferred comes from the sale of preferred stock? The firm's marginal tax rate is 40 percent.

@ 今天,小陳正在慶祝她的 40 歲生日。她的願望是希望在 65 歲退休時,退休後 的 20 年間,每年生日時都能從儲著帳戶中提出$240,000。第一次提款時間是她 的 66 歲生日。小陳打算參加兆豐銀行零存整付專案 (年利率 2%) ,每年生日 時都存入一筆等額現金到此專案帳戶 ,做為退休基金之用。 (1) 如果小陳從 40 歲開始存款,一直到 65 歲 (最後一筆存款是 65 歲生日) ,請問 她每年要存入多少錢才能支應她的退休需求 ? (可先找出以下條件:預計幾年後 退休 ? 退休後每年可領金額 ? 退休儲蓄金可使用年限? ) (2) 假設小陳剛剛很幸運地中了大樂透,所以她決定要改變計畫,不要每年存入等 額的現金,而是在40歲生日時直接存入一大筆可以滿足她退休計畫的錢。請問 大樂透獎金至少要多少錢才夠呢 ? 如果大樂透獎金為$1,500,000 , 請問足以支 應退休計畫嗎?若是可以,請問小陳退休後每年可提領的金額增加多少? 若是不 足以支應,請問小陳每年要再存入多少錢才能支應她的退休需求? ( 假設不考慮 稅賦等影響因素 ) (3) 假設小陳的公司提出員工分紅計畫 ,每年會有$12,500 元分紅直接存在她的儲蔡 帳戶。此外,小陳預期在她 55 歲生日時,可從一筆家族信託基金領到$120,000, 到時她也會把這筆基金直接存到她的退休金帳戶。請問,若有分紅計畫和家族 信託基金的幫助,小陳每年應該還要存入多少錢,來支應她的退休計畫呢?
