1. [Public key revocation procedure] Suppose that a certain authority is running a (publicly accessible) database of users’ public keys. Let us define the following procedure for revoking a public key from the database. When a user Bob claims that the secret key sk_B corresponding to his public key pk_B was stolen, he sends to the authority the statement “Revoke Bob’s public key pk_B”
   which is signed using sk_B . Upon receiving such the statement, the authority revokes pk_B from the database.

Explain why it is not necessary for the authority to check Bob’s identity in this case.
In particular, explain why it is not a problem that an adversary who has stolen Bob’s secret key sk_B can forge signatures for this key.

Hint: Consider the following two cases:

1) Bob’s secret key sk_B was not stolen;

2) Bob’s secret key sk_B was stolen.

Suppose that a certain authority is running a (publicly accessible) database of users’ public keys. Let us define the following procedure for revoking a public key from the database. When a user Alice claims that the secret key skA corresponding to his public key pkA was stolen, she sends to the authority the statement “Revoke Alice’s public key pkA” which is signed using skA . Upon receiving such the statement, the authority revokes pkA from the database. Explain why it is not necessary for the authority to check Alice’s identity in this case. In particular, explain why it is not a problem that an adversary who has stolen Alice’s secret key skA can forge signatures for this key. Hint: Consider the following two cases: 1) Alice’s secret key skA was not stolen; 2) Aice’s secret key skA was stolen.

1-REVENUE/SALES- Based on economic conditions, she believes that the increase in sales for the current year should approximate the historical trend. (Revenues were 20x6: $11,814 20x5: $9,500, 20x4: $7,800) (Industry sales have been increasing by double digits for the last five years, competitor sales increases have ranges from 10-30% increases year over year for the last 5 years.) Using a reasonableness analytic estimate expected revenue for 2018 using the historical data provided.

2.Based on her knowledge of economic conditions, she is aware that the effective interest rate on the company's Long-term debt, less current maturity for 20X8 was approximately 11 percent. She is aware that the company pays little to no interest on the current portion of the long-term debt. Long-term debt, less current maturity is the company’s only debt, and source of interest expense. Using a reasonableness analytic estimate expected interest expense for 20X8. (Show your calculation, your answer, and if any differences noted are material or not, conclude whether you believe this account is misstated or appears reasonable.)

Managerial Epidemiology

Outbreak of Influenza in a Kentucky Nursing Home Assume that an outbreak of Influenza A occurred among 400 residents of a New York Nursing Home during December 2006 and January 2007, despite the vaccination of 375 of them between mid-October and mid-November of 2006. The residents, 70% of whom were female, had a mean age of 85 years and shared common recreational and dining areas. (Textbook Case Study 2.2) Case Questions: Base your reply upon this influenza outbreak case, research of influenza, and proposed solutions. You are to write a 2-3 page paper in APA formatting that addresses the following questions. Note: A minimum of two references should be used, which should include your textbook and the CDC, and others that support your responses in your paper. This is a paper, so your answer should not be numbered, but rather it should use titles and subtitles.

1. If 75 of the residents developed influenza-like illness (ILI), what proportion of the residents became sick?

2. Of those with ILI, 40 developed pneumonia, 25 required hospitalizations, and two died. What proportion of those with ILI developed pneumonia? What percent of those with ILI and pneumonia were hospitalized? What proportion of those with ILI died?

3. Of the 375 residents who were vaccinated, 60 developed ILI. Of the 25 residents who were not vaccinated, 20 developed ILI. What percent of vaccinated residents developed ILI? What percent of unvaccinated residents developed ILI? How many more times higher is the rate of ILI among those who were unvaccinated compared to those who were vaccinated?

4. Of the 375 vaccinated residents, 35 developed pneumonia following ILI compared to 15 residents among the 25 who were not vaccinated. What percent of vaccinated residents developed pneumonia following ILI? What percent of unvaccinated residents developed pneumonia following ILI? How many more times higher is the pneumonia following ILI among those who were unvaccinated compared to those who were vaccinated?

5. What was the vaccine efficacy for preventing LIL and pneumonia?

Case 19-7

Accounting for Contingent Payments to Employees or Selling Shareholders in a Business Combination

Company G (G), an SEC registrant, is a global financial advisory and asset management firm. Company P (P), a private company, offers advisory services for (1) mergers, acquisitions, and divestitures; (2) capital structure (including initial public offerings); (3) government advisory, including strategic, finance and capital markets related policy considerations; and (4) restructurings.

Case Facts

On September 18, 20X8, (the “Closing”), G and P executed an acquisition agreement (the “Agreement”) whereby G acquired 100 percent of the outstanding shares of P (the “Acquisition”). At the time of close, P had 10 employees that had over 200 combined years of financial and strategic advisory experience. Company P was owned as follows:

• Founder — 85 percent.

• Senior advisor — 10 percent.

• Other employees (four in total) — 5 percent.

  The purchase price was calculated using a revenue multiple that was established using market data at the midpoint and transferred in exchange for 100 percent of the outstanding shares to the Founder ÷ employees who owned 100 percent of P (collectively, the “Shareholders”) on a pro rata basis. The total purchase price comprised the following:

  • Cash = $1 million.

  • Shares = 100,000 shares in G (worth $3.3 million).

  • Delayed Consideration = 120,000 G shares, but issued to the Shareholders under the terms below (value assuming a 4-year vesting restriction = $5 million; assuming a 10-year vesting restriction = $4 million).

o Delayed consideration is held by an independent third party (Exchange Co) and on the fourth anniversary of the Closing, Exchange Co shall release the Delayed Consideration to the Shareholders, subject to the Shareholder being employed on such date.

o If a Shareholder is no longer employed on the fourth anniversary, the Delayed Consideration issued to such Shareholder will continue to be held by Exchange Co until the tenth anniversary of the Closing, at which point Exchange Co shall release the Delayed Consideration to the Shareholders.

Case 19-7: Accounting for a Contingent Payments to Employees or
Selling Shareholders in a Business Combination Page 2

• Earnout Consideration = Up to 600,000 shares (valued at total of $20 million).

o The Earnout Consideration will be contingent upon achievement of revenue hurdles over a period beginning on September 18, 20X8, and ending on December 31, 20X2 (“Earnout Period”).

o To the extent the performance targets below are achieved, Exchange Co shall deliver the relevant Earnout Shares to the Shareholders on a pro rata basis. However, if and to the extent certain performance targets described below are not achieved, in whole or in part, no Earnout Consideration will be paid.

•  First Earnout Consideration — If revenue exceeds $10 million in the Earnout Period, the Shareholders will be entitled to 200,000 shares.

•  Second Earnout Consideration — If revenue exceeds $20 million in the Earnout Period, the Shareholders will be entitled to an additional 200,000 shares.

•  Third Earnout Consideration — If revenue exceeds $30 million in the Earnout Period, the Shareholders will be entitled to an additional 200,000 shares.

o The Shareholders are still entitled to the Earnout Consideration in the event that targets are met, but they are not employees of G at the time the Earnout Consideration is earned.

Other Key Facts

• Company P meets the definition of a business under ASC 805.

• Each employment agreement executed by G and the Shareholders contains compensation that is commensurate with the service each respective Shareholder is providing to G.

• The Shareholders have at-will employment agreements with G.

• If the Shareholders were to leave, G would be able to replace them with an existing G investment banker; therefore, the Shareholders are not integral to the future success of the acquired business.

• The fair value of P was determined to be $24 million.

• The Earnout Consideration is not being treated as compensation expense for tax purposes.

Selling Shareholders in a Business Combination Page 3

Required:

If there was a change to the case facts, and the Shareholders were no longer entitled to the Earnout Consideration if they were not employees of G at the time the revenue targets were met, should the Earnout Consideration to the Shareholders be accounted for as purchase consideration in exchange for the Acquisition or as compensation for postcombination services?

Your elder brother Kazim has been hired as CFO in Sohar Power Company SAOG. Sohar Power
company SAOG owns and operates the largest power generation and water desalination plant in
the Sultanate. Sohar Power is incorporated in 2004. Since then, the company has built and owns
the 585 MW electricity generation and 33 MIGD seawater desalination plant. Sohar Power has a
history of research and development in the field of power generation and water purification. It has
a long established policy for the treatment of expenditure on research and development, on which
it spends huge amount annually.
Recently, Kazim becomes aware that an investment of OMR 100,000 which was made last year
for research and development programme, has not been properly evaluated. Although in aggregate
OMR 1 million has been spent, but Kazim thinks that the criteria for the investment was not fair
and clear. The director for the research committee did not assess properly and the output of the
investment was poor. Kazim enquires Mr. Abid, the director of research committee to justify the
investment. Abid replies by saying that they will satisfy the auditors in any way.
However, the financial year end is only two months away and OMR 1 million in write-off at this
late stage in the financial year would cause Kazim and his team in difficulties. The company has
to finalize the year-end report. Kazim called the meeting of directors and discussed the issue.
During the meeting they have serious reservations on research committee. One of the directors
suggested that this amount will be considered as an asset and it will be presented on the financial
statement for this year and it would be write off in the next financial year.
a. In your opinion, what decisions will be taken by Kazim to satisfy the auditors and board of
directors of the company? How this transaction would be reflected on financial statement of Sohar
Power?
b. Abid, working on a high position in a company thinks that auditors can be satisfied in an
unethical manner. How could such an unethical behavior be a learning experience for the rest of
the employees? In your opinion, who is to be blamed for this incident in Sohar Power and why?
