Advanced Technology Ltd is considering the various benefits that may result from a shortening of its production cycle time by changing from the company’s present manual system to a computer-aided manufacturing design/computer-aided manufacturing (CAD/CAM) system. The annual cash expense of maintaining the current manual system is $300,000.

The annual cash expense of maintaining the new CAD/CAM system is estimated to be $180,000, with the initial investment of $445,000. The estimated life of the new CAD/CAM system for taxation purposes is 5 years with zero salvage value.

The taxation rate is 30% and Advanced Technology will use straight-line depreciation method for both accounting and tax purposes. Advanced Technology requires a minimum after-tax rate of return of 14 per cent.

Required:

1. Calculate the following:
   1. After-tax cash flow and after-tax profit.
   2. Payback period.
   3. Net present value.
   4. Internal rate of return.
   5. Accounting rate of return.
2. Beyond the above financial concerns, what other factors should the firm take into account when review this proposal?
3. Overall, should the investment go ahead and why?

You are approaching the end of your time supporting Sifers-Grayson. Your team leader has asked you to prepare a 2 page research and analysis brief ("briefing paper") for the company's executives in which you identify the five most important technologies which the company should adopt in order to improve its security posture.

Provide specific details as to why each technology is required (what is the vulnerability or weakness that the technology will address). Then, make a recommendation for how the company should implement that technology. You must provide specific, actionable information. Your recommendations must also be based upon recognized best practices. Include the following steps in your research and analysis as you select and evaluate technologies, products, and services that will help improve the company's security posture:

• Identify Candidate Technologies
• Research Products and Services which implement the technologies
• Identify Vendors
• Evaluate Products & Services (use existing market research)

Cite the sources of information used in your research and analysis (document where you obtained your information from). Use a professional citation format and provide a reference list at the end of your briefing paper.

The Mizkhan Museum recently deployed the Quuppa positioning system, powered by Bluetooth technology, to improve the interactive visitor experience and gain valuable information on visitor movement throughout the museum. The app-based solution that guides visitors through the museum from the moment they enter the facility, providing highaccuracy location information. Mizkan can use this information to analyse the pattern of visitor flow and gain insight into which exhibits are the most popular. Deployment of the Quuppa system took only a single day and has allowed Mizkan to create a wholly unique experience based on how visitors move throughout the museum.

Walkin Inc. is considering the write-down of its long-term plant because of a lack of profitability. Explain to the management of Walk-in how to determine whether a write-down is permitted.​

Jones, Incorporated acquires 15% of Anderson Corporation on January 1, 2020, for $105,000 when the book value of Anderson was $600,000. During 2020 Anderson reported net income of $150,000 and paid dividends of $50,000. On January 1, 2021, Jones purchased an additional 25% of Anderson for $200,000. Any excess cost over book value is attributable to goodwill with an indefinite life. The fair-value method was used during 2020 but Jones has deemed it necessary to change to the equity method after the second purchase. During 2021 Anderson reported net income of $200,000, and reported dividends of $75,000.
