从表中查询出的内容创建新表显示无效怎么办

有可能是查询出的内容不符合新表的字段规则导致无法创建。您可以尝试以下步骤：

1.检查查询语句是否正确，确保每个字段都有相应的别名并且各个别名之间有正确的逗号分隔。

2.检查新表的字段规则是否和查询出的内容匹配，例如数据类型、长度等，必须严格一致。

3.尝试手动创建新表，确保新表的字段规则正确可行，再将查询出的内容插入到新表中。

4.如果以上步骤都没有解决问题，可以贴出具体的SQL语句和错误提示，我们一起来看看原因所在。

What is the cost of equity for Buzz?

Group of answer choices

1.6%

4.5%

5.6%

6.5%

The cost of equity for Buzz can be calculated using the CAPM formula:

Cost of Equity = Risk-Free Rate + Beta x Market Risk Premium

Risk-Free Rate = 2.5%
Beta = 1.2
Market Risk Premium = 5%

Cost of Equity = 2.5% + 1.2 x 5%
Cost of Equity = 2.5% + 6%
Cost of Equity = 8.5%

Therefore, the cost of equity for Buzz is 8.5%. The correct answer is not provided in the options.

What is the equity beta for Bite if we assume that the debt has a beta of zero?

Group of answer choices

0.8

1.6

2.4

3.2

To calculate the equity beta for Bite, we can use the following formula:

Unlevered Beta = Equity Beta / (1 + (1 - Tax Rate) x (Debt/Equity))

Since we are assuming that the debt has a beta of zero, the unlevered beta for Bite will be equal to its equity beta.

So, if we can calculate the unlevered beta of Bite first, we can then get its equity beta by re-levering the unlevered beta using the company's current capital structure. We are given that the unlevered beta of comparable firms is 1.2.

Unlevered Beta = 1.2
Tax Rate = 40%
Debt/Equity = 0.6/1

Unlevered Beta = Equity Beta / (1 + (1 - Tax Rate) x (Debt/Equity))
1.2 = Equity Beta / (1 + (1 - 0.4) x (0.6))
1.2 = Equity Beta / 1.56
Equity Beta = 1.2 x 1.56
Equity Beta = 1.872

Therefore, the equity beta for Bite is 1.872, which is not provided in the options.

The stock price of company A is consistent with a cost of capital of 6%, whereas that of company B is consistent with a cost of capital of 8%. Based upon your analysis, you believe that the risk and return prospects for both companies are identical. If your analysis is correct then relative to company B, company A is:
Group of answer choices

Overvalued

Fairly valued

Undervalued

Impossible to say

If the risk and return prospects for both companies are identical, then the expected return on investment should be consistent with the risk level of the investment. Since the expected return on investment for both companies is identical, but the cost of capital for company B is higher, then company A must be less risky than company B.

Therefore, relative to company B, company A is undervalued. Its stock price is consistent with a cost of capital of 6%, which suggests that investors are not fully valuing the company's lower risk level. If investors were to correctly account for the lower risk level of company A, the cost of capital would be even lower and the stock price would rise, making the stock undervalued.

Assume that an appropriate Capital Asset Pricing Model Beta for James Halstead is 0.43, that the relevant equity risk premium is 5.8%, and the relevant risk-free rate of interest is 3.6%.
REQUIRED:
Using the assumptions stated above, and information from the annual report provided, calculate showing all workings:
a)
i)	The cost of equity for James Halstead
ii)	Return on equity over the financial year to 30th June 2022				
iii)	Debt to asset ratio
iv)	Debt to equity ratio
v)	Equity to asset ratio
vi)	Cost of debt
vii)	Weighted average cost of capital (WACC)

soluation form article Report & Accounts 2022

a) 
i) The cost of equity for James Halstead:
Cost of equity = Risk-free rate + Beta * Equity Risk Premium
Cost of equity = 3.6% + 0.43 * 5.8%
Cost of equity = 6.22%

ii) Return on equity over the financial year to 30th June 2022: 
Return on equity can be calculated using net income and average equity.
Return on equity = Net income / Average equity
From the annual report, net income is £64.8 million and average equity is £455.5 million. 
Return on equity = 64.8 / 455.5 = 14.2%

iii) Debt to asset ratio:
Debt to asset ratio = Total debt / Total assets
From the balance sheet in the annual report, total debt is £71.4 million and total assets are £602.9 million.
Debt to asset ratio = 71.4 / 602.9 = 0.118

iv) Debt to equity ratio:
Debt to equity ratio = Total debt / Total equity
Total equity can be calculated from the balance sheet in the annual report as total assets minus total debt. 
Total equity = 602.9 - 71.4 = 531.5 million
Debt to equity ratio = 71.4 / 531.5 = 0.134

v) Equity to asset ratio:
Equity to asset ratio = Total equity / Total assets
Equity to asset ratio = 531.5 / 602.9 = 0.881

vi) Cost of debt:
The cost of debt is not provided in the annual report. However, it can be estimated using the interest expense and total debt. From the income statement in the annual report, interest expense is £4.3 million. 
Cost of debt = Interest expense / Total debt
Cost of debt = 4.3 / 71.4 = 6.03%

vii) Weighted average cost of capital (WACC):
WACC = Cost of equity * (Equity / (Equity + Debt)) + Cost of debt * (Debt / (Equity + Debt))
From the calculations above, 
WACC = 0.0622 * (531.5 / (531.5 + 71.4)) + 0.0603 * (71.4 / (531.5 + 71.4))
WACC = 6.05%

a)	Assume that all purchases are credit purchases and that all sales are credit sales. Then using the annual report provided for James Halstead, and showing all your workings calculate using the average balance sheet method, of each of the following where applicable:
i)	Net working capital (NWC) over the most recent financial year
ii)	Accounts payables period
iii)	Raw materials inventory period
iv)	Work in progress period
v)	Finished goods inventory period
vi)	Receivables period
vii)	Cash conversion period.
 soluation from article Report & Accounts 2022

a)
i) Net working capital (NWC) over the most recent financial year:
NWC = Current assets - Current liabilities
From the balance sheet in the annual report, the average current assets are £222.2 million and the average current liabilities are £95.9 million.
NWC = 222.2 - 95.9 = £126.3 million

ii) Accounts payables period:
Accounts payables period = (Accounts payables / Cost of sales) * 365 days
From the income statement in the annual report, the cost of sales is £300.3 million. From the balance sheet, the average accounts payables are £39.1 million.
Accounts payables period = (39.1 / 300.3) * 365 = 47.6 days

iii) Raw materials inventory period:
Raw materials inventory period = (Raw materials inventory / Cost of sales) * 365 days
From the balance sheet in the annual report, the average raw materials inventory is £9.2 million.
Raw materials inventory period = (9.2 / 300.3) * 365 = 11.2 days

iv) Work in progress period:
Work in progress period = (Work in progress / Cost of sales) * 365 days
From the balance sheet in the annual report, the average work in progress is £20.2 million.
Work in progress period = (20.2 / 300.3) * 365 = 25.7 days

v) Finished goods inventory period:
Finished goods inventory period = (Finished goods inventory / Cost of sales) * 365 days
From the balance sheet in the annual report, the average finished goods inventory is £31.9 million.
Finished goods inventory period = (31.9 / 300.3) * 365 = 33.8 days

vi) Receivables period:
Receivables period = (Accounts receivable / Sales) * 365 days
From the income statement in the annual report, the total sales revenue is £357.4 million. From the balance sheet, the average accounts receivable is £62.7 million.
Receivables period = (62.7 / 357.4) * 365 = 64.1 days

vii) Cash conversion period:
Cash conversion period = Raw materials inventory period + Work in progress period + Finished goods inventory period + Receivables period - Accounts payables period
Cash conversion period = 11.2 + 25.7 + 33.8 + 64.1 - 47.6 = 87.2 days
