Year 0 – year 1:
Rate of return, r1 = (Closing price + Dividend + Opening price)/ Opening price Rate of return,
r1= ($16.93 + $0.15- $14.75)/ $14.75
Rate of Return = 0.1580
Year 1 – Year 2.
Rate of Return, R2 = (Closing price + Dividend – Opening price) / Opening price
Rate of Return, R2 = ($17.93 + 0.24 – $16.93), / $16.93
Rate of Return = 0.0732
Year 2 – Year 3.
Rate of Return, R3 = (Closing price + Dividend – Opening price) / Opening price
Rate of Return, R3 = ($16.43 + 0.28 – $17.93), / $17.93
Rate of Return = -0.0680
Year 3 – Year 4.
Rate of Return, R4 = (Closing price + Dividend – Opening price) / Opening price
Rate of Return = r4 = ($18.77 + 0.29 – $16.43)/ $16.43
Rate of Return = 0.1601
Year 4 – Year 5.
Rate of Return, R5 = (Closing price + Dividend – Opening Price)/Opening Price
Rate of Return, R5 = (21.88 + $0.34- $18.77)/ $18.77
Rate of Return, R5 = 0.1838
Arithmetic Return = [r1+r2+r3+r4+r5] / 5.
Arithmetic Return = [0.1580+ 0.0732 + (+0.0680) + (0.1601 + 0.1838]/ 5.
Arithmetic Return = 0.5071/5
Arithmetic Return = 0.1014 / 10.14%
Geometric Return = (1+r1) * (1+r2)* (1+r3) * (1)+r4) * (1+r4) • (1+r5 1/5)
Geometric Return = [1+0.1580] * (1+0.0732) * (1+0.1601) * (1+0.1601) * (1+0.1680) * (1+0.1601) – 1
Geometric Return = 1.5906656 (1/5) – 1
Geometric Return = 1.0973-1
Geometric Return = 0.0973 / 9.73%

Answer: One of the benefits is an increase in image rating if the company has meaningful social responsibilities that are sustained over a long period of time.
Explanation: CSR is a term that refers to the activities of corporations to promote a positive image of themselves in the minds of consumers. This can lead to customers choosing to purchase products from companies that are csr-operating.
Example: P&G products have been reported to contribute to education and other social development. In such cases, even though the price of some products may be higher, customers don’t mind this as they feel the increase in amt will help at least some of the society’s development.
