Overnight Publishing Company (OPC) has $3.8 million in excess cash. The firm plans to use this cash either to retire all of its outstanding debt or to repurchase equity. The firm’s debt is held by one institution that is willing to sell it back to OPC for $3.8 million. The institution will not charge OPC any transaction costs. Once OPC becomes an all-equity firm, it will remain unlevered forever. If OPC does not retire the debt, the company will use the $3.8 million in cash to buy back some of its stock on the open market. Repurchasing stock also has no transaction costs. The company will generate $1,430,000 of annual earnings before interest and taxes in perpetuity regardless of its capital structure. The firm immediately pays out all earnings as dividends at the end of each year. OPC is subject to a corporate tax rate of 23 percent and the required rate of return on the firm’s unlevered equity is 12 percent. The personal tax rate on interest income is 30 percent and there are no taxes on equity distribution. Assume there are no bankruptcy costs. a. What is the value of OPC if it chooses to retire all of its debt and become an unlevered firm? (Do not round intermediate calculations and enter your answer in dollars, not millions of dollars, rounded to the nearest whole number, e.g., 1,234,567.) b. What is the value of OPC if it decides to repurchase stock instead of retiring its debt? (Hint: Use the equation for the value of a levered firm with personal tax on interest income from Problem 9 in the textbook.) (Do not round intermediate calculations and enter your answer in dollars, not millions of dollars, rounded to the nearest whole number, e.g., 1,234,567.) c. What is the value of OPC if the expected bankruptcy costs have a present value of $800,000? (Do not round intermediate calculations and enter your answer in dollars, not millions of dollars, rounded to the nearest whole number, e.g., 1,234,567.)

The Australian economy is "weak",with households weighed down by slow wages growth and higher taxes,the OECD has declared in a report that backs lower interest rates,calls for more government spending and paves the way for unconventional monetary policies.

In its six-monthly review of the global economy,the Paris-based think tank has sharply downgraded its expectations for Australia while raising serious concerns about the level of debt being carried by households.

The Morrison government this week announced $3.8 billion of infrastructure projects would be pulled forward or given additional funding over the next four years. The decision followed calls from the Reserve Bank of Australia (RBA),which has sliced official interest rates to a record low 0.75 per cent,for a lift in public spending plus productivity-enhancing structural reforms.

But economists have warned the new spending will equate to less than 0.1 per cent of gross domestic product (GDP),arguing much more needs to be done to get the economy growing fast enough to bring down the national unemployment rate.

The Organisation for Economic Co-operation and Development (OECD),which noted the global economy was now growing at its slowest rate since the global financial crisis,said it expected Australian GDP to expand by 2.3 per cent this year and next,well short of the federal

government's forecast.

It also expects private consumption,which accounts for about 60 per cent of total economic activity,to barely grow faster than inflation over the next two years.

In March,the OECD was expecting unemployment to start edging down. It has now lifted its forecasts,tipping unemployment to average 5.3 per cent in 2020.

"Economic activity has been weak," the OECD said about Australia. "Private consumption spending has been sluggish,weighed down by slow wage growth and an increase in taxes paid by households."

While the government has argued its recent tax cuts will help households offset slow wages growth,the OECD and other organisations such as the RBA have noted overall tax levels are increasing as the budget returns to surplus.

Research this week from National Australia Bank found Australian household debt was now at a record high of 202 per cent of annual income.

The OECD said high household indebtedness could "exacerbate" any economic shock that hit Australia.

It said with the RBA likely to cut interest rates further,which in turn could feed into a lift in house prices,lending standards might have to be tightened to protect households.

"High household indebtedness means that the authorities should stand ready to tighten macro- prudential policy settings if lower interest rates fuel house price inflation through a sharp pick- up in credit," the OECD found.

While expecting further rate cuts,the organisation said the Morrison government should "loosen fiscal policy" to help get the economy growing faster.

"Fiscal policy is expected to provide little support to economic growth,in accordance with the federal government's commitment to future budget surpluses," it said. "A more expansionary fiscal stance may be warranted given that the economy is growing well below its potential and the relatively low public debt burden.

"At the same time,growth-enhancing tax reforms should be prioritised. These include shifting the tax mix away from direct taxes and inefficient taxes like real estate stamp duty to the GST and land taxation."

Treasurer Josh Frydenberg said the nation's economic fundamentals remained sound,with the country now in its 29th consecutive year of growth.

He said there were "headwinds",particularly due to trade policy tensions that have hit confidence and business investment globally since May,but "the government's focus on productivity-enhancing reform will ensure our economy remains resilient".

"The international challenges are a stark reminder of why we must stick to our economic plan which has delivered lower taxes so you can keep more of what you earn,more infrastructure to boost productivity and which will return the budget back to surplus so we can meet the challenges that lie ahead," he said.

Englehart Company sells two types of pumps. One is large and is for commercial use. The other is smaller and is used in residential swimming pools. The following inventory data is available for the month of March.

Accounting
(a) Assuming Englehart uses a periodic inventory system, determine the cost of inventory on hand at March

31 and the cost of goods sold for March under first-in, first-out (FIFO).

(b) Assume Englehart uses dollar-value LIFO and one pool, consisting of the combination of residential and commercial pumps. Determine the cost of inventory on hand at March 31 and the cost of goods sold for March. Assume Englehart’s initial adoption of LIFO is on March 1. Use the double-extension method to determine the appropriate price indices. (Hint: The price index for February 28/March 1 should be 1.00.) (Round the index to three decimal places.)

Analysis
(a) Assume you need to compute a current ratio for Englehart. Which inventory method (FIFO or dollar-

value LIFO) do you think would give you a more meaningful current ratio?

(b) Some of Englehart’s competitors use LIFO inventory costing and some use FIFO. How can an analyst compare the results of companies in an industry, when some use LIFO and others use FIFO?

Principles

Can companies change from one inventory accounting method to another? If a company changes to an inventory accounting method used by most of its competitors, what are the trade-offs in terms of the conceptual framework discussed in Chapter 2 of the textbook?
