The Sherriton Hotels chain embarked on a new customer loyalty programe in 2017. The 2017 year-end data have been collected, and it is now time for you to determine whether the loyalty program should be continued, discontinued, or perhaps altered to improve loyalty and profitability levels at Sherriton.

Sherriton’s loyalty programme consists of three different customer loyalty levels. All new customers can sign up for the Sherriton Bronze Card, which provides guests with a complimentary bottle of wine per night (at a cost to the chain of $5 per bottle) and $20 in restaurant coupons each night (at a cost to the chain of $10). Bronze customers also receive a 10% discount on the nightly rate. The programme enables the chain to track a member’s stays and activities. Once customers have stayed and paid for 20 nights at any of the chain’s locations worldwide, they are upgraded to Silver Customer status. Silver benefits include

the bottle of wine (costing the chain $5 per bottle per night), $30 in restaurant coupons per night (costing the chain $15), and 20% off every night from the 21st night onwards. A customer who reaches the 50-night level is upgraded to Gold Customer status. Gold status increases the nightly discount to 30% and replaces the $5 bottle of wine with a bottle

of champagne per night (costing the chain is $20 per bottle). Also, $40 in restaurant coupons per night are granted (costing the chain $20). Assume all bottles and coupons offered are used.

The average full price for one night’s stay is $200. The chain incurs variable costs of $65 per night, exclusive of loyalty programme costs. The total fixed costs for the chain are $140,580,000. Sherriton operates 10 hotels, with, on average, 500 rooms each. All hotels are open for business 365 days a year, and approximate an average occupancy rate of around 80%. The following are some loyalty programme characteristics:

Loyalty Number of      Average number of

Programme           customers       nights per customer

Gold 2,430 60

Silver 8,340 35

Bronze 80,300          10

No program 219,000          1

Note that a Gold Customer would have received the 10% discount for his or her first 20 stays, the 20% discount for the next 30 stay s, and the 30% discount only for the last 10 nights. Assume that all programme members signed on to the programme the first time they stayed with one of the chain’s hotels. Also, assume the restaurants are managed by a 100%-owned subsidiary of Sherriton.

Required:

a Calculate the programme’s contribution margin for each of the three programmes, as well as for the customers not subscribing to the loyalty programme. Which of the programmes is the most profitable? Which is the least profitable? Do not allocate fixed costs to individual rooms or specific loyalty programmes.

b Prepare an income statement for Sherriton for the year ended December 31, 201

c What is the average room rate per night? What are average variable costs per night inclusive of the loyalty programme? (

d Explain what drives the profitability (or lack thereof) of Sherriton’s loyalty programme.

Spartan Corporation manufactures quidgets at its plant in Sparta, Michigan. Spartan sells its quidgets to customers in the United States, Canada, England, and Australia.

Spartan markets its products in Canada and England through branches in Toronto and London, respectively. Title transfers in the United States on all sales to U.S. customers and abroad (FOB: destination) on all sales to Canadian and English customers. Spartan reported total gross income on U.S. sales of $11,400,000 and total gross income on Canadian and U.K. sales of $3,800,000, split equally between the two countries. Spartan paid Canadian income taxes of $456,000 on its branch profits in Canada and U.K. income taxes of $532,000 on its branch profits in the U.K. Spartan financed its Canadian operations through a $9 million capital contribution, which Spartan financed through a loan from Bank of America. During the current year, Spartan paid $540,000 in interest on the loan.

Spartan sells its quidgets to Australian customers through its wholly owned Australian subsidiary. Title passes in the United States (FOB: shipping) on all sales to the subsidiary. Spartan reported gross income of $2,040,000 on sales to its subsidiary during the year. The subsidiary paid Spartan a dividend of $703,500 on December 31 (the withholding tax is 0 percent under the U.S.- Australia treaty). Spartan was deemed to have paid Australian income taxes of $346,500 on the income repatriated as a dividend.

a. Compute Spartan’s foreign source gross income and foreign tax (direct and withholding) for the current year.

b. Assume 20 percent of the interest paid to Bank of America is allocated to the numerator of Spartan’s FTC limitation calculation. Compute Spartan Corporation’s FTC limitation using your calculation from question a and any excess FTC or excess FTC limitation (all of the foreign source income is put in the general category FTC basket). (Do not round intermediate calculations.)

Your neighborhood homeowners’ association (HOA) conducted a survey to collect data about people in your neighborhood. Based on the survey results, the HOA will decide what to spend money on. Here are the results of the survey:

• Between one-fourth and one-third of the people in your neighborhood are younger than eighteen years of age.

• Between one-half and two-thirds of the people are over the age of forty.

• Between one-sixth and one-fifth of the people in your neighborhood golf on Saturdays in the summer. Between two-thirds and three-fourths of the people in your neighborhood go to the pool on Saturdays in the summer. The rest prefer indoor activities.

• Your neighborhood has 120 people.

What are the greatest and least numbers of people who are between the ages of eighteen and forty and who prefer indoor activities?

At a certain coffee​ shop, all the customers buy a cup of coffee and some also buy a doughnut. The shop owner believes that the number of cups he sells each day is normally distributed with a mean of 340 cups and a standard deviation of 18 cups. He also believes that the number of doughnuts he sells each day is independent of the coffee sales and is normally distributed with a mean of 180 doughnuts and a standard deviation of 16.

a) The shop is open every day but Sunday. Assuming​ day-to-day sales are​ independent, what's the probability​ he'll sell over 2000 cups of coffee in a​ week?

Data Table

(Determining the Operating Model of a Multi-Profile Company) MultiCorp is a diversified, multi-profile company. Essentially, it is a conglomerate company consisting of three diverse strategic units acting as independent businesses under separate brands in different industry sectors: Unit Alpha, Unit Beta and Unit Gamma. MultiCorp is governed from the central head office, which oversights the three subsidiary business units and their financial performance indicators, though without any operational interventions. Each strategic business unit has its own managing director with full discretion and responsibility over its competitive strategy, investment priorities, budget allocation and ensuing yearly profits. Unit Alpha is in the food manufacturing business. The unit produces and distributes a variety of goods including, but not limited to, vegetables, groceries, meat and dairy products. Each of these product lines requires unique production processes, storage arrangements, transportation approaches and underlying equipment and is organizationally implemented by a separate specialized product department. However, these products are delivered largely to the same circle of customers, including both major retailers and local food shops. All product lines are also served by a number of common unit-wide functions, e.g. HR, finance, accounting, logistics, legal, marketing and sales support. Unit Beta competes in the restaurant business. Specifically, the unit controls a chain of small fastfood restaurants occupying the low-cost market niche. In total, the chain includes more than 80 restaurants located in different geographies and more restaurants are planned to be opened in the foreseeable future. All restaurants offer same interiors, menus, prices, meals and services to their customers and imply standardized policies, working procedures and supporting equipment. However, each restaurant is run separately by a chief manager responsible for its overall financial well-being and all necessary business processes, e.g. recruiting, training, procurement, cooking, servicing, cleaning and complaints management. With the exception of Unit Beta’s lean central office, where chain-wide branding, marketing and other strategic decisions are made, the Page | 7 Asia Pacific International College Pty Ltd. Trading as Asia Pacific International College 55 Regent Street, Chippendale, Sydney 2008: 02-9318 8111 PRV12007; CRICOS 03048D Approved: 14/02/2019, Version 1 restaurants operate independently from each other and even have their own profit and loss statements. Finally, Unit Gamma runs a chain of resort hotels. These hotels gravitate towards the high-end price segment and offer premium-quality services to their customers. Unit Gamma’s competitive strategy implies improving its brand recognition and achieving consistent customer experience. For this purpose, the unit’s leadership plans to standardize all customer-facing and, to a lesser extent, backoffice processes across all hotels of the chain as well as all its suppliers and service providers. Moreover, Unit Gamma also intends to become “closer” to its customers and build lifelong customer relationships. This strategy requires collecting more information about customers, their individual preferences and transaction histories, aggregating this information globally and leveraging it for providing customized services, launching loyalty programs, developing special offers and promoting personalized discounts.
