Me. Chief Justice Hughes
delivered the opinion of the Court.
This is an appeal from a final decree of the District Court, composed of three judges as required by section 266 of the Judicial Code, enjoining the enforcement of an order of the Illinois Commerce Commission which prescribed rates for telephone service in the City of Chicago, upon the ground that the order was confiscatory and hence was in violation of the due process clause of the Fourteenth Amendment (38 F. (2d) 77). The order of the. Commission wg.s made on August 16, 1923, to be effective October 1, 1923. It reduced rates for four classes of coin box service and thus applied to a large part of the intrastate service of the complainant, the Illinois Bell Telephone Company.
An interlocutory injunction, restraining the enforcement of the rates, was granted on December 21,1923, and the order was affirmed by this Court-on October 19, 1925. 269 U. S. 531. This interlocutory order was made upon the condition that, if the injunction were dissolved, the complainant should refund to its subscribers the amounts paid by them in excess of the sums chargeable under the Commission’s order. The suit was not brought to a final hearing until April, 1929, and the court found that at the time of its decision (January 31, 1930) the amount thus reserved for refunds exceeded $11,000,000. The court said that the delay in bringing the case to trial was attributable to-the City of Chicago and that the complainant had been ready at all times to proceed. But the decree enjoining the rates speaks from its date, and the question is necessarily presented, not only whether the order of the Commission was confiscatory when made, but also as to its validity during the period that has intervened, and as to the respective rights of the complainant and’ its subscribers in relation to the fund thus accumulated.

v.
Duluth South Shore & Atlantic Railway Company,
250 U. S. 607, 609.
The court found that ninety-nine per cent, of the stock of the complainant, the Illinois Company, is owned by the American Telephone & Telegraph Company which also owns substantially the same proportion of the stock of the Western Electric Company; that the Illinois and American companies unite in rendering long distance service under an arrangement for a division of tolls; that at the time to which the inquiry related, in October, 1923, there was in effect an agreement by which the Illinois Company paid to the American Company 4% per cent, of its gross revenues for rent of instruments and as compensation for enginering, executive, financial and other services; that a large part of the materials entering’ into the construction of the plant and equipment of the Illinois Company were purchased from the Western Electric Company and much of its operating expense consisted of payments made under a contract with that company for apparatus and supplies. The court further found that the American Company owned a controlling interest in fifteen telephone companies which, in connection with other companies controlled by those subsidiaries and some companies in which its interest was not controlling, were operated as a system with the avowed purpose of rendering a nation-wide and unified telephone service; that the American Company had stated that “ the associated companies are specialists in local service problems, with local operating-forces, identified and familiar with the needs of the communities they serve ”; that “ the parent company undertakes the solution of the problems that- are common to all,” and in this way there was provided a central authority equipped to perform adequately general functions, leaving to the local companies responsibility for local affairs.
Upon these facts the City attacked the standing of the Illinois Company as the real plaintiff in the case.' The
court overruled this contention, holding that the ownership of stock by the American Company, and its power to control the Illinois Company, did not destroy the distinct corporate identity of the Illinois Company. The court pointed out that the order of the Commission was directed against the Illinois. Company, and that it was treated as a corporation for the purpose of compelling it to establish the prescribed rates for service furnished by the operation of the property to which it had legal title. No ground appears for assailing this ruling. The fact that the relation of the Illinois Company to the American Company may demand close scrutiny, in dealing with certain questions which bear upon the validity of the rate order, cannot obscure the essential basis of that order, that is, that the Commission was imposing its requirement upon a corporate organization engaged in an intrastate public service arid, as such, amenable to a valid exercise of the Commission’s authority.
The Commission, in its -final order of August 16, 1923, made the following findings with respect to the value of the property of the Illinois Company: That the original cost as of December 31, 1922, of the property used and useful in the rendering of telephone service in the City of Chicago and exclusive of working capital, materials and supplies, work in progress arid going value, but including overhead, was $90,687,816; that the reproduction cost new of that property, with the same exceptions, wás $128,-769,000; that the property.as it.then existed was “in at least 90 per cent condition ”; that the amount of construction work then in progress, which would eventually be included in capital account, was riot more than $4,250,000; that the amount necessary to provide a sufficient cash working capital and to permit the carrying of .sufficient materials and supplies was $3,000,000; that -the going value of the Chicago property of the Illinois Company was. $4,196,872; that the Chicago division of the Illinois
Company had a depreciation reserve of $26,000,000 which had been contributed by the subscribers of the Company and had been used by the Company for extensions and additions to its property, and that these extensions and additions should not be considered in arriving at a base upon which to compute rates for telephone service; and that the fair rate-making base for the Chicago property of the Illinois Company, “including physical property, overhead, working capital, going value and work in .progress” as thus found was $96,000,000, which was “ exclusive of the $26,000,000 of money taken for depreciation reserve and put into plant and equipment.” The Commission also found that on a readjustment of the account of operating expenses, and on making a fair allowance to take care of maintenance and retirement charges, the existing rates, if permitted to remain in effect'for the ensuing year (1923) would afford a return of nine per cent, upon the rate-base above stated; that this was an excessive rate and that the reduced rates prescribed by the Commission would enable the Company to obtain a return of seven and one-half per cent, upon that rate base.
The court found that the original cost of the property, taking the Commission’s finding of cost as of December 31, 1922, with net additions to June 30, 1923, was $101,-626,014; that the reproduction cost new, as of the latter date, was at least $145,000,000; that the finding'that the property was in 90 per cent, condition was supported by the evidence, and that on this basis the reproduction .cost new, less depreciation, was $130,500,000; that the amount allowed by the Commission, $4,196,067, was the minimum allowance that could be made for going value; that the valuation, or rate basis, of $96,000,000, found by the Commission as of December 31, 1922, or $106,000,000, if the net additions to June 30, 1923, were added, was clearly insufficient, and that the valuation should be not less than $125,000,000, estimating the depreciation at ten per cent.
The court held that the exclusion from the rate base of extensions and additions to the amount of $26,000,000, for which payment had been made from fhe Company's depreciation reserve, was erroneous; that the customers had paid for service, not for the property used to render it, that in paying for service they had not acquired any intérest in the property of the Company, and that profits of the past could not be used to sustain confiscatory rates for the future, citing
Board of Public Utilities Commissioners
v.
New York Telephone Company,
271 U. S. 23, 31, 32.
The court further found that the readjustment made by the Commission of. the Company’s account of operating expenses involved a reduction of $360,000 from the payment made to the American Company under the license contract, and a reduction of $1,800,000 from the annual' allowance for depreciation; that the amount available for return in 1923 on the value of the property under the rates in force was $6,280,000; that if to this amount were added the above deductions on the license contract - and for depreciation there would have been available'for such return the sum of $8,440,000; that the reduction for the entire year under thé rates established by the Commission would have been $1,700,000, thus leaving a return of $6,740,000, or less than five and one-half per cent., whieh was held to be confiscatory under conditions existing in 1923.
At the threshold of the discussion, we are met with the fact that, in these findings, the Commission and the court made no distinction between the intrastate an4 the interstate property and business of the Company. It appears that the property of the Company in Chicago is used to render (1) what is called exchange service, all of which is intrastate, (2) .-intrastate toll service over its own lines and under arrangements with companies other than the American Company, and (3) interstate toll serv
ice, which includes all the toll service rendered under arrangements with the American Company. The Company introduced evidence separating the intrastate, and interstate business and also the intrastate exchange business. While the court regarded these computations as correct, and approved the method in which they had been made, still the court made no specific findings based on a separation of the intrastate and interstate property, revenues and expenses, bujt. determined the. issue on the basis of the total Chicago property of the Company.
The court stated that this was done because that basis was less favorable to the Company than that of its total intrastate property or of its intrastate exchange property. In support of this view, the court, said that according to the computations of the company, one-half of one per cent, of calls originated by subscribers resulted in interstate toll calls; that 3.62 per cent of the Company’s property in Chicago was used in furnishing interstate toll service, and 2.54 per cent, of its property,was used in furnishing intrastate toll service; that both on the reproduction cost new, as claimed by the Company, and on the original cost, the percentage of return was greater for the total Chicago business than for the total intrastate business, and that the return for the latter was greater than for the intrastate exchange business. Considering that the difference would not affect the result, the court deemed it to be more convenient to pass upon the order of the Commission without recasting the figures in order to make allowance for interstate or intrastate toll property and earnings.
The appellants challenge this conclusion.
They insist that the American Company used in its long distance service, without properly reimbursing the Illinois Company, the Chicago local exchange plant, and other facili
ties of the latter company, and that the additional net income to which the Illinois Company wps properly entitled in connection with the long distance service, or that suitably taking into account the value, of
the property used and the expenses incurred in the lorfg distance service and not deducted from the Chicago property and expenses, would affect the result. It is apparent that this contention can not be dismissed simply on the basis of the number of interstate calls originated by subscribers of the Illinois Company in Chicago, without considering other factory of time and labor entering into the. relative use. Nor can the question be disregarded by assuming a rate of. return from the total Chicago bjusiness, as compared with a rate of return from the intrastate business .or the intrastate exchange business, as such an assumption would beg the point in issue.
The. separation, of the intrastate and interstate prop-, erty, revenues and expenses of the Company is important not simply as a theoretical allocation to two branches of the business. It is essential to the appropriate recognition of the competent governmental authority in each field of regulation. In .disregarding the distinction between the interstate and intrastate business of' the Company, the court found it necessary to pass upon the fairness of the division of interstate tolls between the American and Illinois companies. The court held that the division was reasonable and the appellants contest this iuling*. But the interstate tolls are the rates applicable to interstate commerce, and neither these interstate rates nor the division of the revenue arising from interstate rates was a matter for the determination either of the Illinois Commission of of the court in dealing with the order of that Commission. The Commission, would have had no authority. to impose intrastate rates, if as such they would be confiscatory, on the theory that the interstate revenue of the Company was too small and could be increased to
make good the loss. The interstate service of the Illinois Company, as well as that of the American Company,, is subject to the jurisdiction of the Interstate Commerce Commission, which has been empowered to pass upon the rates, charges and practices relating to that service (Interstate Commerce Act, section 1 (1) (c), (3), (5); section 15 (1); section 20 (5)). In the exercise of this.jurisdiction the Interstate Commerce Commission has authority to estimate the value of the property used in the interstate service and to determine the amount of the revenues and the expenses properly .attributable thereto. By section 20 (5) of the Interstate Commerce Act, that Commission is also charged with the duty of prescribing, as soon as practicable, the classes of property for which depreciation charges may properly be included in operating expenses, and the percentages of depreciation which shall be charged'with respect to each of such classes of property. The proper regulation of rates can be had only by maintaining the limits of state and federal jurisdiction, and this cannot be accomplished unless there are findings of fact underlying the conclusions reached with respect to the exercise of each authority. In view of the questions presented in this case, the validity of the order of the state commission can be suitably tested only by an appropriate determination of the value of the property employed in the-intrastate business and of. the compensation receivable for the intrastate service under the rates prescribed.

Railroad Commission
v.
Maxcy,
281 U. S. 82, 83.
.The court found that the Illinois Company owns and operates all the property in the City of Chicago used in interstate calls and connects with the property owned by
the American Company at the city limits. In the method used by the Illinois Company in separating its interstate and intrastate business, for the purpose of the computations which were submitted to the court, what is called exchange property, that is, the property used at the subscriber’s station and from that station
to'
the toll switchboard, or to the toll trunk lines, was attributed entirely to the intrastate service. This method was adopted as a matter of convenience, in view- of the practical difficulty of dividing the property between the interstate and intrastate services.
The appellants insist that this method is erroneous,' and they point the indisputable fact that the subscriber’s station, and the other facilities of the Illinois Company which are used in connecting with the ’long distance toll board, are employed in the'interstate transmission and reception of messages.
While the difficulty in making an exact apportionment of the property is apparent, and extreme nicety is not required, only reasonable measures being essential
(Rowland
v.
Boyle,
244 U, S. 106, 108;
Groesbeck
v.
Duluth South Shore & Atlantic Railway,
250 U. S. 607, 614) it is quite another
matter to ignore altogether the actual uses to which the property is put. It is obvious that, unless an apportionment is made, the intrastate service to which the exchange property is allocated will bear an undue burden — to what extent is a matter of controversy.
We think that this subject requires further consideration, to the end that by some, practical method the different uses of the property may be recognized and the return properly attributable to the intrastate service may be ascertained accordingly.
Other questions are presented growing out of the relation of the Illinois Company to the Western Electric Company and to the American Company. While the Illinois Company is a distinct corporate organization, it has the advantage of being a component part of a large system to which the benefits of its operations accrue. Through this relation the Illinois Company obtains the cooperation of the manufacturing, research, engineering and financing departments of the American Company. This does not alter the fact that the Illinois business is to be treated as a segregated enterprise. If a single individual or corporation, having a number of technical staffs, engaged directly in local public services within several States, each State would be entitled to regulate the transactions within its own domain according to its own conception of public pol
icy, provided there were no infringement of the fundamental rights guaranteed by the Federal Constitution, and, if the latter were invoked by reason of the action of any State, it would still be necessary to consider the local enterprise separately and to make, whatever apportion-ments were necessary in that view. The corporate organization of the Illinois Company not only created a legal person amenable as such to governmental authority, but facilitates the examination of the particular , transactions subject to that authority. The question presented in the present case is not one of the abuse of intercorporate relations, or of domination or control affecting the integrity of the direction of the affairs of the Illinois Company, but of alleged confiscation through prescribed intrastate rates.
Contentions of the appellants in this relation are directed to- the purchases from the Western Electric Company and to the' payments to the. American Company under what is called its “ license contract.” It appears that the Illinois Company has purchased practically all its equipment from the Western Electric Company. The state commission in laying the basis for its rate order made no finding as to the fairness of the prices on such purchases. On the record in this suit, the court concluded that the City had failed to support its contention that these prices were exorbitant. The court said that it appeared that for the past fourteen years the average profit of the Western Electric Company on its total business had not been
“
in excess of seven per cent, and never above ten per cent.” That fact has evidentiary value but the finding does not go far enough. The Western Electric Company not only manufactured apparatus for the licensees of the Bell system but engaged in other large operations and it cannot be merely assumed or conjectured that the net earnings on the entire busiriess represent the net earnings
from the sales to the Bell licensees generally or from those to the Illinois Company. Nor is the argument of the appellants answered by a mere comparison of the prices charged by the Western Electric Company to the Illinois Company with the higher prices charged by other manufacturers for comparable material, or by the Western Electric Company to independent telephone companies. The point of the appellants’ contention is that the Western Electric Company, through the organization and control of the American Company, occupied a special position with particular advantages in relation to the manufacture and sale of equipment to the licensees of the Bell system, including the Illinois Company, that is, that it was virtually the manufacturing department for that system, and the question is as to the net earnings of the Western Electric Company realized in that department and the extent to which, if at all, such profit figures in the estimates upon which the charge of confiscation is predicated. We think that there should be findings upon this point.
At the time to which the evidence was primarily directed (1923), there was in force a
“
license contract ” between the Illinois Company and the American Company, granting a license under the patents owned or controlled by the American Company and providing for the payment to the latter of 4% per cent, of the gross revenues of .the Illinois Company covering the rental for the use of instruments and for engineéring, financial and advisory services. The total amount sought to be charged by the Illinois Company to operating expenses, in 1923, for payments under this contract in relation to the Chicago business was about $1,724,000. The order of the Public Utilities Commission of Illinois, made in December, 1920, which fixed the rates charged in 1923 (the rates still in force under the interlocutory injunction in
this suit) had provided that an allowance of $1.13 was reasonable solely for the use of each telephone instrument, that the services of the American Company were of great value to the Illinois 'Company, that the annual payment under the license contract then averaged $2.10 per station for the City of Chicago, and that this payment was not excessive.
The Illinois Commerce Commission, in the order now under attack, continued this allowance of
$2.10 per station as sufficient to cover the rental and the services in question.
The Illinois Company, in its evidence before the court, presented an estimate ¿lowing that it would have cost that Company the sum of $709,000, or $1.07 per station, during the year 1923 to provide its own supply of instruments, purchasing them in the open market and providing for a return of eight per cent, on the investment. The appellants urge that this amount is too large by $120,000, and that, in any event, the remainder of the total charge of $1,724,000 for payments under the license contract, that is, $1,015,000, treating this amount as compensation for services in addition to rentals, should be rejected. The court overruled this contention. The court found that the case for the allowance of the entire amount for services was a strong one; that on the basis of a total charge of $2.10 per station, as allowed by the state commission, there would be a reduction of $360,000 in the amount chargeable to operating expenses by virtue of the payments under the license contract, and that there was
no warrant for any further reduction.' Without approving the reduction, the court accepted the ruling of ..the Commission for the purpose of determining the issue of confiscation.
It further appears that in the early part of the year 1926, the payment under the license contract was reduced from 4%■ per cent, of the gross earnings to 4 per cent. This reduction was made effective as of January 1, 1926, and the reduced rate was applied in the years 1926 and 1927.
At the end of the year 1927, the conditions of the license contract were again changed by providing for the sale by the American Company to. the Illinois Company of the telephone instruments (receivers, transmitters and. induction coils) and the American Company was relieved from its obligation with respect to their replacement and repair. It is said that the price paid was substantially the current price less 20 per cent. At the. same time the payment under the license contract by the Illinois Company to the American Company was reduced from 4 per cent, to 2 per cent, of the gross earnings.
On January 1, 1929, the
rate of payment was further reduced from 2 per cent, to 1% per cent., of the gross earnings.
There is evidence that the payment under the license contract in the year 1924 exceeded the amount allowed by the state commission by $358,952; in 1925, by $387,284; in 1926, by $223,249; and in 1927, by $251,964. We find no similar statement for the subsequent period under the reductions of rate then applicable. In view of the findings, both of the state, commissions: and of the court, we see no reason ,to doubt that valuable services were rendered by the American Company, but there should be specific findings by the statutory court with regard to the cost of these services to the American Company' and the reasonable amount which should be allocated in this respect to the operating expenses of the intrastate business of the Illinois Company in the years covered by the decree.
There is also the question of. the annual allowancé for depreciation. The Illinois Commission concluded that the accumulation of a large reserve ($26,000,000) despite the fact that the property had been maintained."in at least 90 per cent, condition,” showed that the-reserve had been bup.t up by annual additions that were in excess of the amounts required. The Commission by its order pro
vided for a “combined maintenance and replacement allowance” which it deemed to be adequate “to fully protect the investment in this property and permit the Company to accrue a reserve in the anticipation of property retirements.” The court found that by this method the amount as charged by the Company to operating expenses in 1923 with respect to depreciation had been reduced by the Commission to the extent of about $1,800,-000. It was on the assumption of this reduction, that the court, without making any finding as to the proper, annual allowance for depreciation, reached its conclusion as to the inadequacy of the rates.
While it has beenlield by this Court that property paid, for out of moneys received for past services belongs to the Company, and that the property represented by the credit balance in the reserve for depreciation cannot be used to support the imposition of a confiscatory rate
(Board of Commissioners
v.
New York Telephone Company, supra),
it is evident that past experience is an indication of the Company’s requirements for the future. The recognition of the ownership of the property represented by the reserve does not make it necessary to allow similar accumulations to go on if experiénce shows that these are excessive. The experience of the Illinois Company, together with a careful analysis of the results shown, under comparable conditions, by other companies which.are part of the Bell system, and thus enjoy the advantage of the continuous and expert, supervision of a central technical organization,
should afford a sound basis for judgment as to the amount which in fairness
both to public and private interest should be allowed as an annual charge for depreciation.
The Company urges that, as Congress has granted jurisdiction to the Interstate Commerce Commission over the depreciation rates of telephone companies doing an interstate business (Interstate Commerce Act, section 20 (5) as amended by Transportation Act, 1920) this subject is now completely withdrawn from the power of the State. It is said that two rates of depreciation cannot be charged on the same property. The Interstate Commerce Commission has had the matter under consideration (Telephone and Railroad-Depreciation Charges, 118 I. C. C; 328-333) but, so far as we aré advised, a final determination has not yet been made. The Interstate Commerce Commission has its accounting rules with reference to depreciation charges and, pending its order under section 20 (5) of the Interstate Commerce Act, telephone companies, as well as others subject to the Act, have been directed to continue to observe these requirements. The Company argues that, although the Interstate Commerce Commission has not finally ruled, the action taken by Congress excludes the jurisdiction of state tribunals under familiar principles
(Northern Pacific Railway Company
v.
Washington,
222 U. S. 370, 378;
Pennsylvania Railroad Company
v.
Public Service Commission,
250 U. S. 566, 569;
Oregon-Washington Railroad & Navigation Company
v.
Washington,
270 U. S. 87, 102). We are unable to assent to this view. As the Interstate Commerce Commission has not acted finally in the matter,, we are not now called upon to consider the scope of its authority in relation to depreciation charges, fe¡üt we are of the opinion that, in any event, until action has- been
taken which could be deemed-validly to affect the amount to be charged to depreciation in connection with intrastate business so as to affect intrastate rates, the prerogative of the State to prescribe such rates, and the jurisdiction and duty of the statutory court in considering, their validity to determine the amount properly allowable for depreciation in connection with intrastate business, are not to be gainsaid. Compare
Board of Commissioners
v.
Great Northern Railway
Company, 281 U. S. 412. Accordingly, the court should make appropriate findings with respect to the amount, to be allowed in this case as an annual charge for depreciation in connection with the intrastate business.
Upon the hypotheses adopted by the statutory court, the return to the Illinois Company was found to be inadequate, but what would be a proper rate of return was not determined. In determining what is a confiscatory regulation of .rates, it is necessary to consider the actual effect of the rates imposed in the light of the utility’s situation, its requirements and opportunities. As was said in
United Railways
v.
West,
280 U. S. 234, 249, 250, a rule as to rate of return can not be laid down which would apply uniformly to all sorts of utilities; “what may be a fair return for one may be inadequate for another, depending upon circumstances, locality and risk.” In that case the Court restated the general rule in the language of the opinion in
Bluefield Company
v.
Public Service Commission,
262 U. S. 679, 692, 693, as follows: “What annual rate will constitute just compensation depends upon many circumstances and must be determined by the exercise of a fair and enlightened judgment, having regard to all relevant facts. A public utility is entitled to such rates as will permit it to earn a return on the value of the property which it employs for the convenience of the public equal to that generally being made at the same time and in the same general part of the country
on investments in other business undertakings which are attended, by corresponding risks and uncertainties; but it has no constitutional right to profits such as are realized or anticipated in highly profitable enterprises or speculative ventures. The return should be reasonably sufficient to assure confidence in the financial soundness of the utility and should be adequate, under efficient and .economical management, to maintain and support its credit and enable it to raise the money necessary for the proper discharge of its public duties.”
It is evident that in the present cáse we are not dealing with an ordinary public utility company, but with one that is part of a large system organized for the purpose of maintaining the credit of the constituent companies and securing their efficient and economical management. The record of the Illinois Company shows that for many years.it has been able to expand its business so as to meet increasing demands, to pay its operating expenses including interest on money borrowed, to. pay dividends of. eight per cent, upon its capital stock, and to accumulate a surplus. It was found by the court that the reduction in revenue caused by the rates in question, as applied to the entire business for the year 1923, would amount to about $1,700,000, and the question is whether the loss when ascertained . with respect to the intrastate business would cause confiscation under the applicable standard as above set forth in the
Bluefield
case,
supra.
In order to determine this question, the court should find the rate .of return which was realized from the intrastate business and the rate of return which it is fair to'conclude would have been realized from that business under the prescribed rates. .
The conclusion reached by the court as to confiscation had particular referefice to the evidence bearing upon the business of the year 1923. The court said that this finding applied “with increasing force to the succeeding
years.” But no findings were made as to the value of the property and the revenues and expenses in these years. A rate order which is confiscatory when made may cease tó be confiscatory, or one which is valid when made may become confiscatory at a later period. Des

Commission, supra. In view of this fact, and as the disposition of the amount withheld by the Company under the conditions of the interlocutory injunction will depend on the final decree, there should be appropriate findings as to the results of the intrastate business in Chicago and the effect of the rates in question for each of the years since the date of the Commission’s order.
In order that the necessary findings may be made, and such additional evidence as may be required for that pui^ pose may be received, the decree is set aside and the cause is remanded to the District Court, specially constituted as provided by the statute, for further proceedings in conformity with this opinion, the restraining order entered in this suit to be continued pending further action of the District Court.
It is so ordered
