In a round-robin tournament, every two distinct players play against each other just once. For a round-robin tournament with no

tied games, a record of who beat whom can be described with a tournament digraph, where the vertices correspond to players and there is an edge x→yx→y iff xx beat yy in their game.
A ranking is a path that includes all the players. So in a ranking, each player won the game against the next lowest ranked player, but may very well have lost their games against much lower ranked players —whoever does the ranking may have a lot of room to play favorites.

Prove that every finite tournament digraph has a ranking. Thanks!

Steinberg's equity:

a-2.

Dietrich's debt:

Dietrich's equity:

b. Disagree as the values of the two companies are the same ( please see below Explanation for further clarification)

Explanation:

It is clear to determine that the value of debt and equity of the two firms is the present value of cash flow received in 1 year, discounted at 12%.

a-1.

In one year:

- Debt holder of Steinberg will receive $910,000 regardless of its EBIT. -=> Thus, Steinberg's debt present value = 910,000 / 1.12 = $812,500

- Given the probability of expansion and recession, Steinberg's shareholder will receive the amount equal EBIT -  amount paid to its debt holders: 0.8 x (3,700,000 - 910,000) + 0.2 x (1,100,000-910,000) = $2,270,000.

=> Thus, Steinberg's equity present value = $2,270,000/ 1.12 = $2,026,786

=> Value of Steinberg = D+E = 812,500 + 2,026,786 = $2,839,286 ( note: no tax applied)

a-2.

In one year:

- Debt holder of Dietrich will receive $1,200,000 when the business expands while only $1,100,000 when the business goes into recession (i.e business loss is 100,000):  0.8 x 1,200,000 + 0.2 x 1,100,000 = $1,180,000

=> Thus, Dietrich's debt present value = 1,180,000 / 1.12 = $1,053,571

- Given the probability of expansion and recession, Dietrich's shareholder will receive the amount equal EBIT -  amount paid to its debt holders: 0.8 x (3,700,000 - 1,200,000) + 0.2 x (1,100,000-1,100,000) = $2,000,000.

=> Thus, Dietrich's equity present value = 2,000,000 / 1.12 = $1,785,714

=> Value of Steinberg = D+E =$1,053,571+$1,785,714  = $2,839,286( note: no tax applied)

a-3.

From the calculation, it is clear that the values of the two companies are the same.

Which of the following is an example of a non-penalized religious observance?
tamaranim1 [39]

The correct answer would be option C.

Allowing employees to pray during work time.

Explanation:

Non penalized religious observance means, If someone practice his or her religion during the work hours, as it is compulsory in his/her religion to do so, at the place where he works.

So companies allow employees to pray during work hours which will be a non penalized religious observance for the employees.

For example, If there is a Muslim who works in an organization which is owned by the people of other religion, and if he offers his prayers during his work hours, then the company will respect his offerings and won't charge or penalize him on the observance of his religion during the office timings.

A subsidiary can pay only 50% of its profits to its parent company unless the subsidiary's accumulated retained earnings have be
Aleks [24]

Answer:

False

Explanation:

There is no restriction that prohibits the payment of dividends from a subsidiary to a parent company. The parent company has to report the subsidiary's profit as taxable income, so the subsidiary must pay its dividends to the parent company. To avoid multiple layers of taxation, parent companies can use the dividends-received deduction to reduce their taxes on the dividends received. Then the parent company must itself distribute dividends to its shareholders.

Why is the cost of goods sold account part of a trading business only? The cost of goods sold account is part of a trading busin
ELEN [110]

COGS is sometimes referred to as cost of sales and refers to the production costs for products manufactured and sold or purchased and re-sold by the company. These costs are an expense of the business, and they reduce the revenue the company makes from selling its products.

For example, say your business assembles a completed widget from various inventory parts and sells it online for $15. The parts of the widget and the direct labor required to assemble them cost $10.

The $10 cost is deducted from the widget's sale price to determine the gross profit it generates, and the taxes on that profit. The IRS allows you to include a variety of costs in this calculation.  

Cost of goods sold is determined annually by showing changes in the company's balance of "goods" or inventory, from the beginning to the end of the company's fiscal (financial) year, and it is included in the company's income statement. The income statement information is included on the business tax return and used to calculate adjusted gross income as well as net income for tax purposes.

What's Included in Cost of Goods Sold

Cost of goods sold includes the direct cost of producing the product or the wholesale price of goods resold and the direct labor costs to produce the product. Specifically, it can include:

Cost of raw materials.

Cost of items purchased for resale.

Cost of parts used to construct a product.

COGS also includes other direct costs such as labor to produce the product, supplies used in manufacture or sale, shipping costs, costs of containers, freight in, and overhead costs directly related to the manufacture or production activity (like rent and utilities for the manufacturing facility).

Finally, COGS includes indirect costs such as distribution costs and sales force costs that are also directly related to the products the company sells.
