This is an appeal by the Montana Department of Revenue (DOR) from a judgment entered in the district court, Lewis and Clark County, affirming a final decision of the State Tax Appeal Board (STAB). The STAB decision ordered a recomputation of the deficiency assessment levied by DOR against American Smelting and Refining Company (ASARCO).

In 1972 the auditors of the Multistate Tax Commission conducted an audit of ASARCO's records for the tax years 1967-1970. Subsequent to this audit, additional corporation license taxes were assessed against ASARCO by DOR. The amount of this deficiency assessment is the underlying issue upon appeal.

ASARCO is a New Jersey corporation engaged in national and international operations in the business of mining, smelting, refining, manufacturing, buying and selling nonferrous metals and minerals. ASARCO basically engages in two separate, but related areas of operation. The first is a primary metal operation consisting of the mining, milling, smelting and refining of nonferrous metals. The second is a nonferrous alloy operation consisting of the manufacture and sale of alloy products.

For the tax years in question ASARCO owned mines in Colorado, Washington, Arizona, New Mexico and Idaho in addition to mines in Canada and other foreign countries. It operated smelters and refineries in Texas, Maryland, Colorado, Montana, Missouri, Arizona, Nebraska, New Jersey, Washington and California for the years in question. Alloy manufacturing plants were located in Texas, New Jersey, California, Oklahoma and Indiana. ASARCO sales offices were located in New York, Baltimore, Boston, Cincinnati, Cleveland, Detroit, Milwaukee, Philadelphia, Rochester and St. Louis.

ASARCO owns and operates a smelter in East Helena which is its principal operation in Montana. This smelter receives lead ores and concentrates from company mines as well as unrelated suppliers. This smelted, but unrefined lead product is then shipped to other units of ASARCO for further treatment and eventual sale. Anaconda Company purchased various by-products of the East Helena smelter for the years in question. In addition to the East Helena smelter ASARCO owns certain active and inactive mining properties in Montana.

Prior to 1962 ASARCO reported its income from its Montana properties by separate accounting, pursuant to section 84-1503, R.C.M.1947. Under that method ASARCO determined the gross receipts from its Montana properties and deducted all expenses incurred by or attributable to such properties to arrive at Montana income. Where overhead expenses such as the cost of transportation were attributable to more than one state, they were apportioned to determine the Montana portion.

In 1962 ASARCO recognized that its business was unitary in nature and it could no longer use separate accounting for its income. Pursuant to section 84-1503 it requested permission from DOR to change from separate accounting to the unitary method of accounting. Permission was granted by DOR and a "hybrid" system of reporting income was instituted. Under this hybrid system, all but a negligible amount of total company income from rents, royalties, dividends, interest and sales of tangible and intangible properties was allocated to sources outside Montana. After deductions for the allocated income, ASARCO's operating net income was apportioned to Montana sources by the use of a three factor formula.

An in-depth examination of ASARCO's hybrid system indicates the following procedure was used to compute tax liability for the years in question. ASARCO classified the income listed below as nonbusiness income under DOR's 1967 regulations, deducted it from its apportionable income, and allocated it as indicated:

(a) Income from mine royalties paid by the lessees of ASARCO's Keystone Mine previously operated by ASARCO and located in the State of Colorado was allocated to the State of Colorado;

(b) Income from patents and copyrights on items developed by ASARCO's research department and used in ASARCO's operations and licensed to others, was allocated to commercial domicile;

(c) Income from rental of housing units on mining properties and rented to employes was allocated to the state where such rental units are located (d) Interest income from United States obligations, customers notes and bonds, notes on the sale of a plant and General Cable stock, from state and municipal bonds, time certificates, bankers acceptances, and commercial paper was allocated to the state of commercial domicile;

(e) Gains from the sales of tangible properties were allocated to the state of sale;

(f) Dividends paid on stocks were allocated to state of commercial domicile;

(g) Gains from the sale of stock were allocated to the state of commercial domicile; and

(h) Income from securities deposited with Montana state agencies and from money deposited in Montana was allocated to Montana.

The percentage of apportionable income or loss attributable to Montana sources was calculated by the use of this formula:

                Montana property k   Montana Payroll k   Montana Sales
                -------------------  ------------------  -------------
                   Total ASARCO         Total ASARCO     Total ASARCO
                     Property             Payroll            Sales
                                                            =____%
                ------------------------------------------------------
                                Averaged by dividing by 3
                

The percentage obtained was then multiplied by ASARCO's total apportionable income to determine the Montana contribution.

DOR contends the hybrid system used by ASARCO to calculate its Montana income incorrectly interpreted section 84-1503, R.C.M.1947. That section at the time in question, stated:

"If the income of any corporation from sources within the state cannot be properly segregated from income without the state, then, in that event, the amount of the net income returned shall be that proportion of the taxpayer's total net income which the taxpayer's gross business done in the state of Montana bears to the total gross business of the taxpayer, and apportionment shall be made under the rules and regulations prescribed by the state board of equalization, giving consideration to sales, property and payroll and such other factors as may be deemed applicable; provided, however, that the state board of equalization shall, upon the presentation of satisfactory evidence, determine that the income from sources within the state of Montana may be properly segregated from income from sources without the state of Montana and shall allow separate accounting. The board shall publish not less than once a year, all rules and regulations pertaining to this section. All decisions by the board under this section shall be subject to judicial review in an action prosecuted by the corporation in the district court of Lewis and Clark county. The taxpayer cannot change from one method of accounting to another method of accounting without first obtaining permission from the board."

DOR interprets the above statute as creating only two methods of determining income from sources within Montana separate accounting or apportionment of total net income. Separate accounting is available only if income from sources within the state may be segregated from sources without the state. In the absence of the above conditions, total business net income must be apportioned.

DOR determined that the income classified by ASARCO as nonbusiness income was, in fact, business income as defined by DOR's 1967 regulations. DOR therefore restored this income to apportionable net income. In addition, DOR included in apportionable net income the net income of six of ASARCO's wholly owned subsidiaries. DOR contends that ASARCO and the six subsidiary corporations were engaged in a unitary business and therefore the combination was merely an extension of the apportionment method of taxation dictated by section 84-1503.

Pursuant to DOR's calculations of ASARCO's Montana income additional corporate license taxes were assessed. Protest was made by ASARCO and a hearing was held before the director of DOR. The director's decision affirmed the deficiency assessment. Thereafter ASARCO appealed to STAB which reversed the director's decision. DOR then petitioned the district court, Lewis and Clark County, requesting a review of the STAB order. On December 17, 1975, the district court entered judgment affirming the decision of STAB. DOR appeals the district court judgment.

Three issues are before the Court upon appeal:

1) Whether DOR had the authority, pursuant to sections 84-1503 and 84-1508, R.C.M. 1947, to adopt its Regulations 1001-1020 (Chapter 10) concerning rules for the apportionment of corporate net income?

2) Whether ASARCO was correct in its deduction of alleged nonbusiness income from apportionable net income prior to apportionment?

3) Whether the income from six of ASARCO's wholly owned subsidiaries was properly included in apportionable net income?

On December 30, 1966, DOR adopted its Regulations 1001-1020 (Chapter 10). These regulations were effective with respect to tax years beginning on and after January 1, 1967. Included within these regulations are specific rules for allocation and apportionment of corporate income derived from sources both within and without Montana. In addition key terms are specifically defined as to their application...
