Let's calculate the equivalent annual cost (EAC) for both machines. What’s the first step for defender?

Student 1
Student 1

We need to convert the initial cost to an annualized cost.

Teacher
Teacher

Right! For defender, we take the current market value of ₹22,50,000. Using the formula for EAC, what do we do next?

Student 2
Student 2

We apply the capital recovery factor to find it.

Teacher
Teacher

Exactly! After calculations, we find the defender's EAC to be ₹5,93,550. Now what about operating costs?

Student 3
Student 3

That remains as is since it's already annualized.

Teacher

Defender vs. Challenger Equipment Costs

Unlock Audio Book

So, this is all about your defender that is the current equipment. Now let us discuss about the challenger, that is a proposed equipment. The challenger's annual operating and maintenance cost is 90,000. So, you can see that it is lesser than your old equipment, so lesser than your defender. So, the defender operating and maintenance cost is 1,35,000 but your challenger operating cost is 90,000, so it is lesser.

Detailed Explanation

In this chunk, we start by discussing two pieces of equipment: the defender, which is currently used, and the challenger, which is proposed as a replacement. The key point here is about the operating and maintenance costs. The defender has an annual cost of 1,35,000, while the challenger has a lower cost of 90,000. This is significant because lower costs typically lead to savings over time, making the challenger an attractive option to consider for replacement.

Examples & Analogies

Imagine you're considering two cars: your current car costs you $1,350 a year for maintenance, while a newer car would only cost $900 a year. Choosing the newer car means you save $450 every year, which could be significant over time.

Salvage Value and Investment Cost

And the salvage value for the challenger is 12,00,000 after 5 years. So, the life of the challenger we are considering is for 5 years, investment cost is 10% per year.

Detailed Explanation

This chunk highlights the salvage value associated with the challenger equipment. After five years, the estimated salvage value of the challenger is set at 12,00,000. This means if the equipment is sold at the end of its useful life, it can still fetch a good price. Additionally, it mentions an investment cost of 10% per year, indicating that the company should consider this rate when evaluating the total costs of owning and operating the equipment over time.

Examples & Analogies

Think of it like buying a smartphone that costs $1,000. After two years, you can sell it for $400; that $400 is akin to the salvage value. If you invested that $1,000 at a 10% return annually, you'd also need to consider the interest you could have earned instead of spending it.

Replacement Analysis Considerations

Now we are supposed to compare the challenger and the defender, find out whether the defender should be retained or replaced with the challenger using time value or annual worth method.

Detailed Explanation

This chunk sets the stage for the critical analysis process. The task is to compare the costs associated with both the defender and challenger to determine if the defender should be kept or replaced by the challenger. The analysis will utilize methods such as time value of money and annual worth calculations to ensure that comparisons consider not only costs but also the timing of those costs.

Examples & Analogies

It's similar to deciding whether to keep an old laptop or buy a new one. You'd evaluate the costs of maintaining the old laptop versus the cost of a new one, factoring in how much more efficient and useful the new laptop might be.

Ignoring Irrelevant Estimates

Unlock Audio Book

Signup and Enroll to the course for listening the Audio Book

As I told you, your initial estimates should be ignored or neglected, they are not relevant. Your initial purchase price 35,00,000 should not be considered in the replacement analysis, nor should the initial estimate of salvage value 7,00,000 or the estimated current book value using your depreciation accounting method 23,80,000.

Detailed Explanation

This chunk discusses the importance of focusing on relevant data in the replacement analysis. The speaker emphasizes that previous estimates regarding the initial purchase price, salvage value, and book value should not influence the current analysis because they do not represent the current market conditions. The goal is to assess only cost factors true to the present time.

Examples & Analogies

It’s like deciding not to include the price you paid for your house ten years ago when assessing its current value. Instead, you should focus on similar homes in your area that have sold recently to get an accurate view of what your home is worth today.

Understanding Sunk Costs

Also, as I told you, your sunk cost, so what is sunk cost? It is an estimated book value of the machine, currently 3,80,000. But your current trading value is only 22,50,000. This difference cannot be recovered. This difference is called as the sunk cost.

Detailed Explanation

This portion clarifies the concept of sunk cost, which refers to costs that have already been incurred and cannot be recovered. In this case, the estimated book value of the defender equipment is 3,80,000, but the current trading value is significantly higher at 22,50,000. The difference is a cost that cannot be recovered if the equipment is sold, and as such, it should not factor into the decision-making process for replacement.

Examples & Analogies

Imagine you spent $500 on concert tickets, but now you feel unwell and can't go. The money spent is a sunk cost—whether you go or not, it’s lost. You shouldn't let that cost influence your decision about attending another concert in the future.

Relevant Cost Considerations

For the replacement analysis of the existing equipment that is defender, the relevant factors include the current market value is 22,50,000, the estimated salvage value is 6,00,000, and the annual operating and maintenance cost is 1,35,000.

Detailed Explanation

In this chunk, we focus on the relevant costs to be included in the replacement analysis for the defender. The current market value is important as it reflects what the defender can sell for now. The salvage value of 6,00,000 noted for the end of five years also matters, as does the annual operating cost of 1,35,000, which represents a recurring expense that needs to be considered when evaluating total costs.

Examples & Analogies

Think about a treadmill you may want to sell. To decide if you should keep it or buy a new one, you’d look at what similar treadmills are selling for now (current market value), consider what it could be worth when you sell it in a few years (salvage value), and account for the yearly costs of maintenance and electricity it consumes.
