Cost behaviour; scatter plot Polar Bear Ski Wear is a shop that sells skiwear at a ski resort. Its cost accountant developed the following scatter plot for the cost of electricity for lights, heating, and cooling against retail sales revenue.                             Required (a)          In a business such as retail sales, what usually causes the cost of electricity to vary? (b)          In what time of year would most skiwear be sold at a ski resort? (c)           In the scatter plot, the cost of electricity appears to be related to volume of retail sales. If this shop specialised in selling swimwear, would the scatter plot look different? Explain what would change. (d)          Identify and explain another cost that is similar in nature to the cost of electricity. When you plot the cost against a cost driver, a relationship becomes apparent. However, the cost varies with something other than the cost driver. (Think of other situations where this type of relationship might occur.)

Wilton, Inc. had net sales in 2014 of $1,400,000. At December 31, 2014, before adjusting entries, the balances in selected accounts were: Accounts Receivable $250,000 debit, and Allowance for Doubtful Accounts $2,400 credit. If Wilton estimates that 2% of its net sales will prove to be uncollectible, prepare the December 31, 2014, journal entry to record bad debt expense.

14   Sustainability threats and opportunities The World Coal Institute claims that coal provides over 26.5 per cent of global primary energy needs and generates over 41.5 per cent of the world’s electricity. Coal is one of the cheapest forms of fuel available on the planet. However, burning fuel produces carbon dioxide which contributes to excessive greenhouse gas emissions and global warming. Rather than change energy sources, Clean Coal Technologies (CCTs) have been promoted as a means of reducing emissions, reducing waste as well as increase the efficiency (or amount of energy) gained from coal.72   Required Referring to the information in this problem and drawing on comprehensive example 2, discuss some of the sustainability management threats and opportunities for the future of Australian coal producers.

Roundtree Manufacturing Co. is preparing its year-end financial statements and is considering the accounting for the following items. 1. The vice president of sales had indicated that one product line has lost its customer appeal and will be phased out over the next 3 years. Therefore, a decision has been made to lower the estimated lives on related production equipment from the remaining 5 years to 3 years. 2. The Hightone Building was converted from a sales office to offices for the Accounting Department at the beginning of this year. Therefore, the expense related to this building will now appear as an administrative expense rather than a selling expense on the current year’s income statement. 3. Estimating the lives of new products in the Leisure Products Division has become very difficult because of the highly competitive conditions in this market. Therefore, the practice of deferring and amortizing preproduction costs has been abandoned in favor of expensing such costs as they are incurred. Identify and explain whether each of the above items is a change in principle, a change in estimate, or an error.
