How would you, as a job interviewer analyze a candidate`s potentials, capability, dedication, attention to details? I think these are factors that should be included during the interview and discussed with professional references. It is easy for someone to stretch the truth, so I think it would be difficult to rely on the self-evaluation of the interviewee. What other sources would you use to learn more about a job applicant?

A1 Systems Inc. is a U.S.-based company that prepares its consolidated financial statements in accordance with U.S. GAAP. The company reported income of $8,000,000 in 2014 and stockholders’ equity of $30,000,000 as of December 31, 2014.
The CFO of A1 Systems has learned that the U.S. Securities and Exchange Commission (SEC) is considering requiring U.S. public firms to use IFRS in preparing consolidated financial statements. The company wishes to determine the impact that a switch to IFRS would have on its financial statements and has engaged your team to prepare a reconciliation of income and stockholders’ equity from U.S. GAAP to IFRS. Your team has identified the following five major areas in which accounting principles based on U.S. GAAP differ from those of IFRS.
Inventory
At year-end 2014, inventory had a historical cost of $5,000,000, a replacement cost of 4,750,000, a net realizable value of $4,800,000, and a normal profit margin of $900,000.
Property, plant, and equipment
The company acquired a building on 1/1/2012 at a cost of $10,000,000. The building has an estimated useful life of 30 years, an estimated residual value of $1,000,000, and is being depreciated on a straight-line basis. On 1/1/2013, the building was appraised and determined to have a fair value of $11,150,000. There is no change in estimated useful life or residual value. In a switch to IFRS, the company would use the revaluation model to determine the carrying value of PP&E subsequent to acquisition.
Impairment of Assets
The company purchased a piece of equipment on 1/1/2014 at a cost of $1,000,000. The equipment is expected to have a useful life of 10 years and no residual value. The straight-line method of depreciation is used. Technological innovations took place in the industry during 2014. At year-end 2014, the equipment is determined to have a selling price of $800,000 with zero-cost to sell. Expected future cash flows from continued use of the equipment are $950,000, and the present value of the expected future cash flows is $825,000.

An insurance company sells a two-year term life insurance policy to
an 80-year-old woman. The woman pays a premium of $1,000 per year.
If she dies within one of the insured years, the insurance company
will pay $20,000 to her beneficiary. According to the US Centers
for Disease Control and Prevention, the probability that an
80-year-old woman will be alive one year later is 0.9516 and the
probability that an 80-year-old woman will be alive two years later
is 0.9512 Find the expected value for the insurance company for
that two year term policy.
