The income statement, also known as the profit and loss (P&L) statement, provides a snapshot of the financial performance of a company during a specified period of time. It reports a firm's gross income, expenses, net income, and the income that is available for distribution to its preferred and common shareholders. The income statement is prepared using the generally accepted accounting principles (GAAP) that match the firm's revenues and expenses to the period in which they were incurred, not necessarily when cash was received or paid. Investors and analysts use the information given in the income statement and other financial statements and reports to evaluate the company's financial performance and condition. Consider the following scenario: Green Caterpillar Garden Supplies Inc.'s income statement reports data for its first year of operation. The firm's CEO would like sales to increase by 25% next year. Green Caterpillar is able to achieve this level of increased sales, but its interest costs increase from 10% to 15% of earnings before interest and taxes (EBIT). The company's operating costs (excluding depreciation and amortization) remain at 60% of net sales, and its depreciation and amortization expenses remain constant from year to year. The company's tax rate remains constant at 40% of its pre-tax income or earnings before taxes (EBT). Complete the Year 2 income statement data for Green Caterpillar, then answer the questions that follow. Be sure to round each dollar value to the nearest whole dollar. Green Caterpillar Garden Supplies Inc. Income Statement For Year Ending December 31 Given the results of the previous income statement calculations, complete the following statements: In Year 2, if Green Caterpillar has 5,000 shares of preferred stock issued and outstanding, then each preferred share should expect to receive in annual dividends. If Green Caterpillar has 400,000 shares of common stock issued and outstanding, then the firm's earnings per share (EPS) is expected to change from in Year 1 to in Year 2. Green Caterpillar's before interest, taxes, depreciation and amortization (EBITDA) value changed from in Year 1 to in Year 2. It is to say that Green Caterpillar's net inflows and outflows of cash at the end of Years 1 and 2 are equal to the company's annual contribution to retained earnings. This is because ________

10. You are given a large unordered array of n integers a[1], a[2], a[n]. It is known that one of the integers in the array occurs (i.e., is duplicated) at least n/10 times and the remaining integers are all distinct. (a) Without writing any code, explain how could you find this integer in average time O(nlogn). (2 marks) (b) The function partition(a, L, U) returns the value p after permuting the elements of the subarray a[L], a[L+1], ..., a[U] so that, if the initial value of a[L] is t: a[k] ?t for L? k <p, a[p] = t, and a[k] ?t for p <k<U. By making use of this function and employing the cutoff idea used in the qsort4 version of Quicksort, or otherwise, without necessarily giving a detailed algorithm, explain how you could find the duplicated integer in average time O(n). Briefly explain why you think that the average time complexity of your algorithm will be O(n). (6 marks)

Blue Hamster Manufacturing Inc. is a small firm and several of its managers are worried about how soon the firm will be able to recover its initial investment from Project Omega's expected future cash flows. To answer this, net cash flows are assumed to be received evenly throughout each year. Complete the following table and compute the project's conventional payback period. Year 0: -4,500,000 Year 1: $1,800,000 Year 2: $3,825,000 Year 3: $1,575,000 Expected cash flow: Cumulative cash flow: Conventional payback period: The conventional payback period ignores the time value of money, and this concerns Blue Hamster's CFO. He has now asked you to compute Omega's discounted payback period, assuming the company has a 9% cost of capital. Complete the following table and perform any necessary calculations. Round the discounted cash flow values to the nearest whole dollar, and the discounted payback period to the nearest two decimal places. Year 0: -4,500,000 Year 1: $1,800,000 Year 2: $3,825,000 Year 3: $1,575,000 Cash flow: Discounted cash flow: Cumulative discounted cash flow: Discounted payback period: Which version of a project's payback period should the CFO use when evaluating Project Omega, given its theoretical superiority? - The regular payback period - The discounted payback period One theoretical disadvantage of the net present value method is that it fails to consider the value of the cash flows beyond the payback period. How much value does the theoretical deficiency have? $4,435,615 $1,586,991 $2,867,565 $1,216,189
