How much is the return on Sony Group's dividends?
If you bought Sony Group's shares a year ago and continued to hold them, you can receive two dividends for the interim and year-end of the fiscal year ending March 2022.
Assuming that the return is confirmed at the dividend record date.
In this verification, the following assumptions are made.
- Share acquisition date: August 23, 2021
- Share acquisition price: 0.01 million 1000 yen (closing price on acquisition date)
- Interim dividends for the fiscal year ending March 2022: 30 yen
- Year-end dividends for the fiscal year ending March 2022: 35 yen
- Return on dividends on a basis of 100 shares: 6,500 yen
Next, we will calculate the return on shareholder benefits.
What is the return on shareholder benefits for the Sony Group?
Sony Group provides electronic coupons for discounts that can be used on Sony's official online store "Sony Store" and Sony Store outlets in each region to shareholders who own 100 shares or more listed on the shareholder register as of the end of March each year.
AV products receive a 15% discount and VAIO main units receive a 5% discount.
For example, when you view a Sony LCD television, the "BRAVIA X90J Series," at the Sony Store, the price is listed as 1.87 million yen~, and in this case, the discount amount would be 180,500 yen.
Therefore, the return on shareholder benefits is 180,500 yen.
