X. Only After-Tax Gains Considered
The OIR proposed that any rule we develop here apply only to after-tax gains. In this way, if a sale caused a taxable gain, we would only allocate the net proceeds after taxes were paid.
The comments do not address the taxation issue, with one exception. ORA/TURN note that SCE includes the entire pre-tax gain in its "Other Operating Revenue" (OOR) account: "The inclusion of the entire gain in other operating revenue generates a reduction to the utility's taxable income that offsets the tax paid at the time of the gain . . . ."63
SCE states that it believes ORA, TURN and SCE share a mutual understanding and agreement with regard to the treatment of taxes in the allocation of gains and losses. SCE clarifies that tax treatment of gains/losses depends on whether the Commission adopts "flow-through" or "normalized" tax accounting.64
The California Supreme Court in Southern California Gas Company v. Public Utilities Commission, 23 Cal. 3d 470, 475-76 (1979) noted that the Commission's ordinary policy is to require flow-through, or cash-basis, tax accounting:
[T]he commission [has] generally taken the position that rates . . . should reflect only actual costs incurred. As taxes are treated as part of a utility's cost of service, any tax savings should not be retained by the utility but should be immediately passed on to the utility's customers. Accordingly, since 1960 the commission has required utilities to charge as operating expenses only the amount of taxes actually paid. Any savings acquired through the use of accelerated depreciation or the investment tax credit is to be immediately flowed through to the ratepayers.
Where flow-through tax accounting is used, SCE states that the Commission's gain on sale policy should "ensure that any tax benefits or detriments . . . passed along in rates to ratepayers are essentially `recaptured' by ratepayers before allocating the gains or losses to shareholders."65 SCE continues: "To accomplish this [recapture], shareholders' allocated gain or loss should be equal to the pre-tax gain or loss, minus the product of the composite income tax rate times the pre-tax gain or loss."
The rules we develop here apply to after tax gains and losses. No party opposes such a rule, and it makes sense since taxes reduce or alter the actual gains or losses available for allocation to shareholders and ratepayers.
The mechanism for the distribution of gains through OOR described by ORA/TURN and SCE derives from D.87-12-06666 and applies to the sales of land and timber. The distribution of the gain through this mechanism depends, among other things, on the amount of time the property was included in rate base. However, SCE's OOR from the sale of non-tariffed products and services is distributed in an entirely different manner through D.99-09-070.67
The distribution of OOR varies widely among the other utilities. It is beyond the scope of this proceeding to specify the precise method for distributing the gains to particular accounts such as OOR; our purpose here is to provide guidelines to help determine the amount of gain to allocate to each of the parties. This decision does not supersede D.87-12-066, nor does it recommend its mechanisms for the distribution of OOR to other utilities. It would not be prudent to impose the mechanism currently used by SCE to distribute a specific type of OOR on all utilities. Further, a tax treatment designed for a specific OOR distribution method should not be imposed on all methods. There is nothing in the statements of either SCE or ORA/TURN that would suggest we should apply these rules to anything other than after tax gains.

64 There are two methods to account for income tax expense for regulatory purposes. Under the flow-through method, the income tax expense recognized for regulatory purposes during a given period is equal to the taxes that are assessed and paid during the period. Under the normalization method, the income tax expense for a given period is based on the net income recognized for regulatory accounting purposes during the period, regardless of when the taxes associated with the accounting income are actually paid. The flow-through method can be viewed as cash-basis accounting, while the normalization method reflects accrual accounting.
