A na lys is o f Fo recasting M ethods

Analysis of Linear Trending Method:

If the linear trending results yielded acceptable R-squared statistics, the historical trend and the forecast results were evaluated to determine if linear trending was the appropriate forecasting method for the development o f the test year forecast. However, based on the retirement o f both Units 2 & 3 at SONGS, using a linear trending forecast method would yield an inaccurate forecast and, therefore, was not selected.

Analysis of Averaging Method:

Averaging was used if historical operating expenses showed significant annual fluctuations from year to year. Although labor and non-labor expenses have fluctuated over the last five years, the averaging method was not selected as the estimating method. The averaging method is based on historical information that is not indicative o f the future. The last recorded year forecasting method more accurately reflects current operations and is the appropriate forecast base to determine the expenses required to support activities in the test year.

Analysis of Last Recorded Year (2012):

Last recorded year was selected as the primary estimating method for SONGS 2&3 O&M accounts as it more accurately reflects current business expenses and activities. O ther factors considered in the selection of the last recorded year forecasting method were stable or consistent historical trends and acceptable R-squared statistics. Although labor and non-labor expenses have fluctuated over the last five years, the last recorded year was selected as the forecasting method because it reflects the most accurate base O&M from which future year adjustments were made. Using the 2012 Base Year as a forecast base, labor (headcount reduction) and non-labor expenses were subtracted to reflect the estimated base O&M in the test year. These adjustments are described in our testimony and in our workpapers.

Analysis of Itemized Forecast Method:

A na lys is o f Fo recasting M ethods

Analysis of Linear Trending Method:If the linear trending results yielded acceptable R-squared statistics, the historical trend and the forecast results were evaluated to determine if linear trending was the appropriate forecasting method for the development of the test year forecast. However, based on the retirement of both Units 2 & 3 at SONGS, using a linear trending forecast method would yield an inaccurate forecast and, therefore, was not selected.

Analysis of Averaging Method:Averaging was used if historical operating expenses showed significant a nnual fluctuations from year to year. Although labor and non-labor expenses have fluctuated over the last five years, the averaging method was not selected as the estimating method. The averaging method is based on historical information that is not indicative of the future. The last recorded year forecasting method more accurately reflects current operations and is the appropriate forecast base to determine the expenses required to support activities in the test year.

Analysis of Last Recorded Year (2012):Last recorded year was selected as the primary estimating method for SONGS 2&3 O&M accounts as it more accurately reflects current business expenses and activities. Other factors considered in the selection of the last recorded year forecasting method were stable or consistent historical trends and acceptable R-squared statistics. Although labor and non-labor expenses have fluctuated over the last five years, the last recorded year was selected as the forecasting method because it reflects the most accurate base O&M from which future year adjustments were made. Using the 2012 Base Year as a forecast base, labor (headcount reduction) and non-labor expenses were subtracted to reflect the estimated base O&M in the test year. These adjustments are described in our testimony and in our workpapers.

Analysis of Itemized Forecast Method:Not applicable.

Analysis of Linear Trending Method:

If the linear trending results yielded acceptable R-squared statistics, the historical trend and the forecast results were evaluated to determine if linear trending was the appropriate forecasting method for the development o f the test year forecast. However, based on the retirement o f both Units 2 & 3 at SONGS, using a linear trending forecast method would yield an inaccurate forecast and, therefore, was not selected.

Analysis of Averaging Method:

Averaging was used if historical operating expenses showed significant annual fluctuations from year to year. Although labor and non-labor expenses have fluctuated over the last five years, the averaging method was not selected as the estimating method. The averaging method is based on historical information that is not indicative o f the future. The last recorded year forecasting method more accurately reflects current operations and is the appropriate forecast base to determine the expenses required to support activities in the test year.

Analysis of Last Recorded Year (2012):

Last recorded year was selected as the primary estimating method for SONGS 2&3 O&M accounts as it more accurately reflects current business expenses and activities. O ther factors considered in the selection of the last recorded year forecasting method were stable or consistent historical trends and acceptable R-squared statistics. Although labor and non-labor expenses have fluctuated over the last five years, the last recorded year was selected as the forecasting method because it reflects the most accurate base O&M from which future year adjustments were made. Using the 2012 Base Year as a forecast base, labor (headcount reduction) and non-labor expenses were subtracted to reflect the estimated base O&M in the test year. These adjustments are described in our testimony and in our workpapers.

Analysis of Itemized Forecast Method:

Not applicable.
