Method of Accounting for ADFIT Related to NOL Carryforward

Southwestern Public Service Company ("SPS") has no Accumulated Deferred Federal Income Taxes ("ADFIT") related to a consolidated Net Operating Loss ("NOL") Carryforward. This ADFIT was historically derived from deductions claimed by SPS for losses sustained from claiming bonus depreciation as allowed by Rev. Proc. 2011-26 and charitable contributions for tax year 2012.

Internal Revenue Code Section 170 required this charitable contribution carryforward to convert to an NOL carryforward with the filing of the 2012 federal income tax return because the consolidated group's taxable income was completely offset by a separate NOL carryforward. SPS's NOL carryforward was utilized as the consolidated group recognized sufficient taxable income.

SPS accounts for ADFITs related to NOL carryforwards under Accounting Standards Codification 740. The ADFIT related to the small amounts of bonus depreciation and charitable contributions are recorded in the non-regulated sections of SPS's financial statements. Thus, it was not included in rate base calculations.

SPS accounts for ADFITs related to losses sustained from bonus depreciation in the regulated sections of SPS's financial statements.

The following iournal entrv is used to record the provision for NOL Carrvforwards:

Debit Current Tax Expense - Non-Operating (FERC Acct. 409.2);

Credit Taxes Payable (FERC Acct. 236);

Debit Accumulated Deferred Income Taxes -Non-Operating (FERC Acct. 190.24); and

Credit Provision for Deferred Income Taxes - Credit - Non-Operating (FERC Acct. 411,2).

The following journal entry is used to record the utilization ofNOL Carrvforwards: Debit Taxes Payable (FERC Acct. 236):

Credit Current Tax Expense - Non-Operating (FERC Acct. 409.2):

Debit Provision for Deferred Income Taxes - Non-Operating (FERC Acct. 410.2); and

Credit Accumulated Deferred Income Taxes -Non-Operating (FERC Acct. 190.24).
