AI summary The document presents two depreciation procedures—Average Life Group (ALG) and Equal Life Group (ELG)—showing how depreciation accruals and balances vary over time. While total depreciation recovered is the same ($2,000), the distribution of accruals and accumulated depreciation differs significantly between the two methods.

In both figures the X-axis reflects years and the Y-axis reflects the calculated dollar value. Figure 10 – Madsen Example 1 Comparison of ALG vs ELG procedure accumulated depreciation As [Figure 9](#page-27-0) shows, the depreciation accru...

AI summary The text compares the ALG and ELG depreciation procedures, highlighting that the ELG method results in higher depreciation accruals in earlier years and lower in later years. This leads to higher customer payments initially and lower payments later. Experts argue that the ALG method provides a more balanced recovery of asset costs. Changes in asset life expectancy also affect depreciation calculations.

s. This change in life expectancy requires a depreciation analyst to recover the difference in the book versus calculated accumulated depreciation reserve over the remaining life of the assets so that there is not an over or under-recovery...

AI summary The text discusses the need to adjust depreciation calculations to account for changes in asset life expectancy, ensuring accurate recovery of asset value over their remaining life. This is done using the remaining life technique outlined by Gannett Fleming in its depreciation study.

Q: Please provide your concluding remarks on the results of the examples highlighted above. A: Regardless of the depreciation procedure employed, neither procedure will perfectly mirror the actual lives of the assets. This is because the a...

AI summary The response discusses the limitations of depreciation procedures in accurately reflecting asset lifespans and emphasizes the importance of a gradual and moderate depreciation expense. It argues that the ALG procedure is preferable as it better achieves the goal of not shifting costs unfairly between generations.

Q: Does reliance on simulated retirements have an impact on whether the ELG procedure should be relied upon? A: Yes. While the ELG procedure can still be used with simulated plant data, the ELG procedure, as explained earlier, places signi...

AI summary Reliance on simulated retirements impacts the ELG procedure's accuracy. The ELG method depends heavily on retirement data fitting the selected Iowa curve, with more reliable data leading to better results. Simulated data, as shown in the Gannett Fleming study, closely aligns with the curve, while real data from Concentric Energy Advisors shows more variation.

AI summary The text discusses differences in depreciation practices between NS Power and NB Power, highlighting variations in asset retirement data and proposed asset lives. It notes that NB Power uses actual aged data, while Gannett Fleming relies on simulated data, potentially leading to different conclusions. NS Power proposes more aggressive depreciation acceleration compared to NB Power.

1 For all these reasons, the use of the ELG procedure exacerbates the potential error when 2 simulated aged data is relied upon as the conclusions that are drawn are less likely to be 3 based on the actual history of retirements had they b...

AI summary The document discusses the ELG and ALG procedures for estimating depreciation expense, highlighting that while both are acceptable, the ALG procedure is more commonly used and preferred by regulators due to its gradual and moderate approach. The ELG procedure may exacerbate potential errors when relying on simulated aged data.

Q: What are the pros and cons of the ALG and ELG procedures? A: As discussed earlier it is impossible for any depreciation expert to conclude that one depreciation procedure will, with certainty, provide for a better and more accurate reco...

AI summary The response discusses the limitations of both ALG and ELG depreciation procedures, noting that neither can guarantee accurate recovery of depreciation expense over an asset's life. It suggests focusing on mechanical considerations and highlights the theoretical advantage of the ELG procedure in estimating depreciation expense.

• ELG procedure pros: - o Accuracy The ELG procedure is dependent on the selected survivor curve, which can significantly influence the amount of depreciation expense. For example, shifting a curve from a 15-R2.5 curve to a 15-R2.0 curve m...

AI summary The ELG procedure enhances accuracy by allowing more variation in depreciation expense through the use of different survivor curves. It also improves cash flows by accelerating the collection of depreciation expense during the construction of rate base investments, which benefits utilities in the short term.

• ELG procedure cons: o Variability – Differences in the selected survivor curve can have significant impact on the depreciation expense in a negative manner as well. Assuming a 15-year average life but selecting either an L1.0, S1.0 or R1...

AI summary The ELG procedure has two main drawbacks: variability in depreciation expense due to different survivor curves and complexity in implementation. While the procedure can improve accuracy, it may also increase inaccuracy if curves are not reflective of asset retirement patterns. The complexity of the procedure may hinder customer understanding, which is a key rate design criterion.

• ALG procedure pros: - o Simplicity The ALG procedure is simple to apply and understand. Complex models are not required to understand or perform the individual calculations. As explained earlier, if a 45-R1 or 45-L2 life curve is selecte...

AI summary The ALG procedure is praised for its simplicity and reduced volatility. It uses straightforward calculations and is less affected by year-to-year changes in retirement data unless there is a significant shift in average service life.

• ALG procedure cons: - o Lower cash flows – Cash flows under the ALG procedure will be lower as the non-cash depreciation charge is reduced as compared to the ELG procedure, at least in the earlier years of investment. In the later years...

AI summary The ALG procedure results in lower initial cash flows due to reduced depreciation charges compared to the ELG procedure, but higher depreciation charges in later years. The ALG procedure is less sensitive to survivor curve selections, making adjustments to depreciation expense more challenging. The choice between ALG and ELG procedures affects depreciation recovery timing, influencing investment incentives and financial strategies for utilities.

1 As a simple example, assume a utility has $1 billion in rate base and is recovering that rate 2 base through depreciation at a rate of $100 million per year. Under this scenario, in order 3 for the utility to make the same amount in retu...
