administrative officers acting within their powers. Mere error or
unwisdom is not equivalent to abuse of discretion. P.

2. Statements made in argument by counsel for the Government in
behalf of the Federal Communications Commission, which were reduced
to writing and filed in the case at the suggestion of the Court,
and which declared the meaning of certain of the regulations
prescribed by the Commission as part of a uniform system of
accounts for telephone companies under the Communications Act of
1934
held an administrative construction binding upon the
Commission in its future dealings with the companies. P.
299 U. S.
241.
3. Rules in a uniform system of accounts for telephone companies
subject to the Communications Act of 1934 require that the property
investments of an accounting company shall be entered in balance
sheet accounts under the general title of "Investments" at
"original cost," a term which, as applied to plant, franchise,
patent rights, etc., is defined to mean the cost, actual or
estimated, of the property at the time when it was first dedicated
to the public use, whether by the accounting company or a
predecessor public utility; the differences between the amounts
actually paid by the accounting company in acquiring property from
predecessor utilities
Page 299 U. S. 233
and this "original cost" (actual or estimated) of the property
shall be recorded in another account entitled "Telephone Plant
Acquisition Adjustment," and shall be disposed of, written off, or
amortized in such manner as the Commission may direct.
Held:
(1) That, in the light of administrative construction, the
regulation does not mean that the differences entered in the
Adjustment Account must be written off completely; on the contrary,
amounts in the Adjustment Account which represent investment by the
accounting company in assets of continuing value are to be retained
in the account until such assets cease to exist or are retired, and
provision is to be made for their amortization. Pp.
299 U. S. 237,
299 U. S.
240.
(2) Reservation of ultimate disposition of items in this
Adjustment Account to await further inquiry and direction by the
Commission does not render the classification arbitrary, or amount
to a departure from the statutory power to prescribe the "forms" of
accounts for classes of carriers, rather than for individuals. P.
299 U. S.
242.
(3) As to property acquired from other utilities, the companies
are not prevented from recovering depreciation expense which they
actually incur, on their actual investment, nor required to base
depreciation charges on cost to prior owners. The provisions of the
regulations as to depreciation or amortization comply with § 220(b)
of the Act. P.
299 U. S.
242.
(4) The requirement that an estimate of the original cost to a
predecessor utility shall be recorded when the actual cost is
unknown is not arbitrary; nor does it expose the accounting company
to the hazard of criminal prosecution. P.
299 U. S.
244.
(5) To subject an accounting company or its officers to criminal
prosecution for violation of the Act, the violation must have been
knowing and willful. Communications Act, §§ 501, 502. P.
299 U. S.
245.
(6) Should duties imposed by the rules on an accounting company
be uncertain, it may obtain clarifying instructions from the
Commission. P.
299 U. S.

4. Another of the instructions in the system of accounts above
mentioned declares:
"All charges to the accounts prescribed in this classification
for telephone plant, income, operating revenues, and operating
expenses shall be just and reasonable, and any payments by the
company in excess of such just and reasonable charges shall be
included in account 323, 'Miscellaneous income charges.'"
Held:
(1) The purpose of this requirement is to prevent the padding of
the accounts by charges knowingly and willfully entered in excess
of what is just and reasonable. Only if knowingly and willfully so
entered is any penalty prescribed by the Act. P.
299 U. S.
246.

(2) The requirement is not arbitrary. P.

5. The rules require that property "used in telephone service at
the date of the balance sheet" go into one account, property "held
for imminent use in telephone service" under a definite plan for
such use into another, and other property held for future use not
imminent or definite into a third account which covers
"miscellaneous physical property."
Held not open to
objection on the ground of vagueness. Property held for imminent
use in telephone service and under a definite plan will include
spare plants kept in reserve as a measure of prudent
administration. Property held in present telephone use comes very
near to defining itself. If particular situations shall develop
ambiguity or doubt, the Commission will be available for clarifying
instructions. P.

6. The evidence does not show that the order of the Commission,
by requiring revision of accounts, lays an unreasonable burden of
expense upon the telephone companies.

Supp. 121 affirmed.
Appeal from a decree which dismissed in part a bill brought
against the United States and the Federal Communications Commission
by numerous telephone companies to set aside an order of the
Commission prescribing a uniform system of accounts. Other
telephone companies intervened as plaintiffs, and the National
Association of Railroad and Utilities Commissioners intervened as
defendant. There was no cross-appeal from that part of the decree
which was favorable to the plaintiffs.
Page 299 U. S. 235
MR. JUSTICE CARDOZO delivered the opinion of the Court.
This suit was brought in the United States District Court for
the Southern District of New York to set aside an order of the
Federal Communications Commission prescribing a uniform system of
accounts for telephone companies subject to the Communications Act
of 1934. Act of June 19, 1934, c. 652, 48 Stat. 1064, 47 U.S.C. §
151
et seq.. The plaintiffs are forty-four telephone
companies, thirty-seven of them members of the Bell system, and
seven of them members of another group. The defendants are the
United States and the Federal Communications Commission, with whom
the National Association of Railroad and Utilities Commissioners
was afterwards joined, intervening as the representative of the
regulatory commissions of forty-six states in support of the
contested order.
The Communications Act of 1934 provides (section 220) that "the
Commission may, in its discretion, prescribe the forms of any and
all accounts, records, and memoranda" to be kept by carriers
subject to the act, "including the accounts, records, and memoranda
of the movement of traffic, as well as of the receipts and
expenditures of moneys." This is a power that had previously been
lodged with the Interstate Commerce Commission (Interstate Commerce
Act, § 20(5)), which framed a set of rules for telephone companies
to take effect January 1, 1913, and a revised set of rules
effective January 1, 1933.
Page 299 U. S. 236
After the transfer of jurisdiction over telephone companies from
the Interstate Commerce Commission to the Federal Communications
Commission in 1934, the new Commission prepared a "draft of a
Uniform System of Accounts," which was considered at a conference
with representatives of the companies and of the state commissions.
The outcome of the conference was the order of June 19, 1935, to
take effect January 1, 1936, which is the subject of this suit.
The plaintiffs having moved for an interlocutory injunction, the
cause was heard, in accordance with the requirement of the statute
(47 U.S.C. § 402(a); 28 U.S.C. § 47), by a District Court of three
judges, the affidavits in support of the motion and against it
being also submitted for and against the final decree. Five
provisions of the order were attacked as arbitrary. The District
Court sustained two objections of minor importance, which are not
in controversy now, and overruled the others. One of these was
directed to the "original cost" rule; the second to a provision as
to "just and reasonable" charges; the third to a classification
dividing plants in present use from those held for use thereafter.
The court dismissed the bill as to the objections overruled,
stating in an opinion the reasons for its action.
14 F.
Supp. 121. The case is here upon appeal. 48 Stat. 1064, 1093, §
402(a), 47 U.S.C. § 402(a); 38 Stat. 219, 220, 28 U.S.C. §§ 47,
47a.
This Court is not at liberty to substitute its own discretion
for that of administrative officers who have kept within the bounds
of their administrative powers. To show that these have been
exceeded in the field of action here involved, it is not enough
that the prescribed system of accounts shall appear to be unwise or
burdensome or inferior to another. Error or unwisdom is not
equivalent to abuse. What has been ordered must appear to be "so
entirely at odds with fundamental principles of correct
Page 299 U. S. 237
accounting" (
Kansas City Southern Ry. Co. v. United
States, 231 U. S. 423,
231 U. S. 444)
as to be the expression of a whim, rather than an exercise of
judgment.
Norfolk & Western Ry. Co. v. United States,
287 U. S. 134,
287 U. S. 141;
Kansas City Southern Ry. Co. v. United States, supra, p.
231 U. S. 456.
Then too, in gauging rationality, regard must steadily be had to
the ends that a uniform system of accounts is intended to
promote.
"The object of requiring such accounts to be kept in a uniform
way, and to be open to the inspection of the Commission, is not to
enable it to regulate the affairs of the corporations not within
its jurisdiction, but to be informed concerning the business
methods of the corporations subject to the act, that it may
properly regulate such matters as are really within its
jurisdiction."
Interstate Commerce Comm'n v. Goodrich Transit Co.,
224 U. S. 194,
224 U. S. 211;
cf. Kansas City Southern Ry. Co. v. United States, supra,
p.
231 U. S. 445.
With these principles in mind, we proceed to consider separately
the regulations and instructions now challenged as unlawful.
First:
The Original Cost Provisions.
Four new balance sheet accounts, each of them a subtitle of the
general title of "Investments," must be kept under the new system.
The first (100.1) is described as Telephone Plant in Service; the
second (100.2), Telephone Plant under Construction; the third
(100.3), Property held for Future Telephone Use, and the fourth
(100.4), Telephone Plant Acquisition Adjustment. Account 100.1
"shall include the original cost [defined by Instruction 3 (S. 1)]
of the company's property used in telephone service at the date of
the balance sheet." Account 100.2 "shall include the original cost
(as so defined) of construction of telephone plant not completed
ready for service" at such date. Account 100.3 "shall include the
original cost [so defined] of property owned and held for imminent
use in telephone service under a definite plan for such use." The
term "original cost" as
Page 299 U. S. 238
appearing in these rules receives under Instruction 3 (S. 1) a
special definition.
"'Original cost,' or 'cost,' as applied to telephone plant,
franchises, patent rights, and right-of-way, means the actual money
cost of (or the current money value of any consideration other than
money exchanged for) property at the time when it was first
dedicated to the public use, whether by the accounting company or
by a predecessor public utility."
If actual costs are unknown, estimates are to take their place.
Instruction 21(B). From all this it follows that the sum of the
three accounts which represent the original cost of property
acquired by the accounting company from other telephone utilities
may be less or greater than the investment in such property by the
accounting company itself. The difference is taken care of by
account 100.4, Telephone Plant Acquisition Adjustment.
* The same rule
provides in a subdivision designated (C) that
"the amounts recorded in this account [
i.e., 100.4]
with respect to each property acquisition shall be disposed of,
written off, or provision shall be made for the amortization
thereof in such manner as this Commission may direct."
Before explaining the appellants' objections to these provisions
as to cost, we may pause to indicate the reasons that led to their
adoption. To a great extent, the telephone business as conducted in
the United States is
Page 299 U. S. 239
that of a far-flung system of parent, subsidiary, and affiliated
companies. The Bell system is represented in this case by
thirty-seven companies, the American Telephone & Telegraph
Company at their head. Seven other companies, intervening as a
group, represent a second and smaller system. Purchases are
frequently made by a member or members of a system from affiliates
or subsidiaries, and with comparative infrequency from strangers.
At times, obscurity or confusion has been born of such relations.
There is widespread belief that transfers between affiliates or
subsidiaries complicate the task of ratemaking for regulatory
commissions and impede the search for truth. Buyer and seller in
such circumstances may not be dealing at arm's length, and the
price agreed upon between them may be a poor criterion of value.
Dayton Power & Light Co. v. Public Utilities Comm'n of
Ohio, 292 U. S. 290,
292 U. S. 295;
Western Distributing Co. v. Public Service Comm'n of
Kansas, 285 U. S. 119;
Smith v. Illinois Bell Telephone Co., 282 U.
S. 133. Even if the property has been acquired by treaty
with an independent utility or a member of a rival system, there is
always a possibility that it is nuisance value only, and not market
or intrinsic value for the uses of the business, that has dictated
the price paid. Accordingly, the work of the Commission may be
facilitated by spreading on the face of the accounts a statement of
the cost as of the time when the property to be valued was first
acquired by a utility or dedicated to the public use. The same
considerations show why the regulations do not direct that the
inquiry as to original cost shall be carried even farther back, so
as to cover, for illustration, the cost to manufacturers who may
have sold to the first utility. In the process of analysis, inquiry
is halted at the point where it ceases to be fruitful.
With this explanatory background, we can now go forward with
understanding to a statement of the objections to the order and a
determination of their weight.
Page 299 U. S. 240
(a) The companies object that, by the "original cost" provisions
of the order, they are prevented "from recording their actual
investment in their accounts." with the result that the accounts do
not fairly exhibit their financial situation to shareholders,
investors, tax collectors, and others.
The argument is that account 100.4, representing the difference
between original and present cost, is not to be reckoned, either
wholly or in part, as a statement of existing assets, but must be
written off completely. The Commission is charged, we are told,
with a mandatory duty to extinguish the entire balance recorded in
that account, its presence under the title of "investments" having
the effect of a misleading label. To give support to that
conception of official duty, they rely on subdivision (C), which
provides, as we have seen, that
"the amounts recorded in this account with respect to each
property acquisition shall be disposed of, written off, or
provision shall be made for the amortization thereof in such manner
as this Commission may direct."
If subdivision (C) had the meaning thus imputed to it, there
would be force in the contention that the effect of the order is to
distort in an arbitrary fashion the value of the assets. But the
imputed meaning is not the true one. The Commission is not under a
duty to write off the whole or any part of the balance in 100.4, if
the difference between original and present cost is a true
increment of value. On the contrary, only such amount will be
written off as appears, upon an application for appropriate
directions, to be a fictitious or paper increment. This is made
clear, if it might otherwise be doubtful, by administrative
construction. Thus, the Commission's chief accountant testified
that, by the proper interpretation of account 100.4, amounts
therein
"would be disposed of, after the character of the item had been
determined, in a manner consistent with the general rules
underlying the uniform
Page 299 U. S. 241
system of accounts for the distribution of expenditures,
according to their character, to operating expenses, income,
surplus, or remain an investment."
Other witnesses gave testimony in substance to the same effect.
But even more decisive are statements made by counsel appearing for
the Government and arguing the case before us. To avoid the chance
of misunderstanding and to give adequate assurance to the companies
as to the practice to be followed, we requested the Assistant
Attorney General to reduce his statements in that regard to writing
in behalf of the Commission. He did this, and informs us that
"the Federal Communications Commission construes the provisions
of Telephone Division Order No. 7-C, issued June 19, 1935,
pertaining to account 100.4"
as meaning
"that amounts included in account 100.4 that are deemed, after a
fair consideration of all the circumstances, to represent an
investment which the accounting company has made in assets of
continuing value will be retained in that account until such assets
cease to exist or are retired, and, in accordance with paragraph
(C) of account 100.4, provision will be made for their
amortization."
We accept this declaration as an administrative construction
binding upon the Commission in its future dealings with the
companies.
Hicklin v. Coney, 290 U.
S. 169,
290 U. S. 175;
Addy Co. v. United States, 264 U.
S. 239,
264 U. S. 245.
The case in that respect is sharply distinguished from
New York
Edison Co. v. Maltbie, 244 App.Div. 685, 281 N.Y.S. 223; 271
N.Y. 103, 2 N.E.2d 277, where, under rules prescribed by the Public
Service Commission of New York, there was an inflexible requirement
that an account similar in some aspects to 100.4 be written off in
its entirety out of surplus, whether the value there recorded was
genuine or false. The administrative construction now affixed to
the contested order devitalizes the objection that the difference
between
Page 299 U. S. 242
present value and original cost is withdrawn from recognition as
a legitimate investment.
We are not impressed by the argument that the classification is
to be viewed as arbitrary because the fate of any item, its
ultimate disposition, remains in some degree uncertain until the
Commission has given particular directions with reference thereto.
By being included in the adjustment account, it is classified as
provisionally a true investment, subject to be taken out of that
account and given a different character if investigation by the
Commission shows it to be deserving of that treatment. Such a
reservation does not amount to a departure from the statutory power
to fix the forms of accounts for "classes" of carriers, rather than
for individuals. The forms of the accounts are fixed, and fixed by
regulations of adequate generality. What disposition of their
content may afterwards be suitable upon discovery that particular
items have been carried at an excessive figure must depend upon
evidentiary circumstances, difficult to define or catalogue in
advance of the event. If once there was any need for explanation
more precise than that afforded by the order, it is now supplied,
we think, by an administrative construction, which must be read
into the order as supplementary thereto.
(b) The companies object that, by the provisions as to "original
cost," they are prevented "from recovering depreciation expense,
which they actually incur, on their actual investment," and are
required "to base depreciation charges on the cost to a prior
owner."
This objection, like the one last considered, has its origin in
the belief that what is recorded in "telephone plant acquisition
adjustment" must inevitably be written off, and is not subject to
the treatment appropriate to genuine assets.
Here again, the construction of the regulations by the
Commission itself is enough to dispel the fear that, in their
practical operation, they will become instruments
Page 299 U. S. 243
of hardship. Without dwelling on the testimony, we content
ourselves with a quotation from the statement filed by counsel at
the conclusion of the argument. The Commission there informs us
that,
"when amounts included in account 100.4 are deemed, after a fair
consideration of all the circumstances, to be definitely
attributable to depreciable telephone plant, provision will be made
for amortization of such amounts through operating expenses,
through the medium of either account 613 [which covers the
amortization of intangible property] or account 675 [which includes
all operating expenses not properly chargeable to other
accounts]."
Obviously, account 675 was inserted as a catch-all to cover
previous omissions. We do not need to inquire whether, under an
ideal system of accounting, the amounts to be amortized would be
chargeable to an account entitled in some other way. It is enough
that, by the ruling of the Commission, they will find a lodgement
here, with an appropriate entry betokening their meaning. A system
of accounts may be awkward or imperfect, and yet not so "arbitrary
and outrageous" (
Norfolk & Western Ry. Co. v. United
States, supra, p.
287 U. S. 143)
as to justify a court in restraining its enforcement.
Appellants insist that amortization is an afterthought as
applied to the account in controversy, and that there must be an
amendment of the rules if the Commission is to resort to such a
process. We read the record otherwise. In setting up the
amortization reserve account (172), the rules expressly provide
that
"it shall also be credited with any amounts which the Commission
may authorize under a plan to amortize the balance in account
100.4, Telephone Plant Acquisition Adjustment."
In the same connection, the point is made that § 220(b) of the
Act requires more specific directions as to depreciation or
amortization than the Commission has supplied. By that section,
"the Commission shall, as soon as practicable, prescribe . . .
the classes of property for
Page 299 U. S. 244
which depreciation charges may be properly included under
operating expenses."
No objection is made that the directions are not sufficiently
specific as to account 100.1, Telephone Plant in Service. The
objection is confined to account 100.4. But one of the very reasons
for establishing that account is that, in advance of inquiry by the
Commission as to the property there included, it is impracticable
to determine what portion of it may properly be subjected to
charges of this nature. When that inquiry has been completed, the
Commission will be in possession of the necessary data. Provision
will then be made for amortization of any amounts in the account
that may properly be classified as investment in depreciable
property. The label is unimportant, whether depreciation or
amortization, if the substance of allowance is adequately
preserved.
(c) The companies object that, by the "original cost" provisions
of the order, they are required, where the actual cost is unknown,
to record an estimate of cost, and that this requirement is an
arbitrary one, mutilating their accounts and exposing them to the
hazard of criminal prosecution.
What was ordered by the Commission in that behalf is expressly
authorized by the statute, with the result that to invalidate the
order will be to invalidate the statute also. By § 213(c) of the
Communications Act of 1934, it is provided that,
"if any part of such cost cannot be determined from accounting
or other records, the portion of the property for which such cost
cannot be determined shall be reported to the Commission and, if
the Commission shall so direct, the original cost thereof shall be
estimated in such manner as the Commission may prescribe."
In the vast majority of cases, original cost will be
ascertainable from the records of the previous owners. If these
have been lost, or are not available or trustworthy, the order
makes provision for the substitution of an estimate. Difficulties
in the making of such an estimate are
Page 299 U. S. 245
indicated by the companies. We doubt whether, in any instance,
they will be found to be insuperable, but, if they shall ever prove
to be so, means will be at hand whereby an avenue of escape from
injustice will be opened without resort to the drastic remedy of
declaring the order void. Estimates are at times inevitable in any
system of accounts. Even under the system previously in vogue, the
total purchase price, which was entered in an account known as
"telephone plant," was subdivided into a series of accounts
covering respectively pole lines, cable, aerial wire, and other
classes, and distributed among them. If the price was a lump sum,
there was need to resort to estimates in the process of
subdivision. So also, estimates were always necessary upon the
retirement of plant or equipment acquired at varying dates, unless
the articles retired were so clearly identified that the dates of
acquisition and the prices then paid for each of them were
susceptible of ascertainment upon the face of the accounts
themselves. All that can be said of the present regulations is that
they make the occasion for estimates more frequent than in former
years, and the process more involved. The difference in degree is
not proved to be so great as to drag nullity in its train. If
instances shall occur in which a company is unable to make an
intelligent estimate with even approximate correctness, that
exceptional event will justify resort to the Commission for
particular instructions. In no event is there a substantial hazard
of criminal prosecution. To subject the company or its officers to
prosecution for a crime the violation of the Act must have been
knowing and willful. Communications Act of 1934, §§ 501, 502;
Hygrade Provision Co. v. Sherman, 266 U.
S. 497,
266 U. S.
502-503;
United States v. Murdock, 290 U.
S. 389. Penalties do not follow upon innocent
mistakes.
(d) The companies object also that, even when property recorded
in the adjustment account (100.4) is recognized by the Commission
as a continuing investment,
Page 299 U. S. 246
there will be difficulty in determining the amount to be written
out of that account when the property is withdrawn. No reason is
apparent why this difficulty should be any greater than it would be
if the same property had been recorded in a single plant account
without separation of the original cost from the cost at later
dates. However that may be, there is ample provision in the rules
for clarifying instructions whenever duty is uncertain.
Second:
The Provisions for Just and Reasonable
Charges.
The companies object to the following instructions, described as
2(B.1):
"All charges to the accounts prescribed in this classification
for telephone plant, income, operating revenues, and operating
expenses shall be just and reasonable, and any payments by the
company in excess of such just and reasonable charges shall be
included in account 323, 'Miscellaneous income charges.'"
The purpose of this requirement is to prevent the padding of the
accounts by charges knowingly and willfully entered in excess of
what is just and reasonable. Only if knowingly and willfully so
entered is any penalty prescribed therefor.
United States v.
Murdock, supra. There is surely nothing arbitrary in
establishing a standard of behavior so consistent with good morals.
On the contrary, the need for such a standard has been made
manifest for years as the result of intercorporate relations that
are matters of common knowledge.
Dayton Power & Light Co.
v. Public Utilities Comm'n of Ohio, supra; Lindheimer v. Illinois
Bell Telephone Co., 292 U. S. 151.
"The Commission must have power to prevent evasion of its orders
and detect in any formal compliance or in the assignment of
expenses a 'possible concealment of forbidden practices.'"
Smith v. Interstate Commerce Commission, 245 U. S.
33,
245 U. S. 45. In
such a context, the standard of the "just and reasonable" is not
unduly vague.
Nash v. United States, 229 U.
S. 373,
229 U. S. 377;
International Harvester Co. v. Kentucky, 234 U.
S. 216,
Page 299 U. S. 247
234 U. S. 223;
United States v. Cohen Grocery Co., 255 U. S.
81,
255 U. S. 92;
United States v. Wurzbach, 280 U.
S. 396,
280 U. S. 399;
People v. Mancuso, 255 N.Y. 463, 470, 175 N.E. 177.
"Moreover, . . . since the statutes require a specific intent to
defraud in order to encounter their prohibitions, the hazard of
prosecution which appellants fear loses whatever substantial
foundation it might have in the absence of such a requirement."
Hygrade Provision Co. v. Sherman, supra.
Third:
The Classification of Plant as Used in Present
Service or Held for Use Thereafter.
Property "used in telephone service at the date of the balance
sheet" goes into account 100.1; property "held for imminent use in
telephone service" under a definite plan for such use goes into
account 100.3, and other property held for future use not imminent
or definite goes into still another account, 103, which covers
"miscellaneous physical property."
The companies object that this classification is so vague as to
be arbitrary. We do not look at it that way. Property held for
imminent use in telephone service and under a definite plan will
include spare plants kept in reserve as a measure of prudent
administration. Such uses had consideration by this Court in a
recent opinion.
Columbus Gas & Fuel Co. v. Public Utilities
Comm'n of Ohio, 292 U. S. 398.
Property held in present telephone use comes very near to defining
itself. If particular situations shall develop ambiguity or doubt,
the Commission will be available for clarifying instructions.
Fourth: the evidence does not show that the expense of revising
the accounts will lay so heavy a burden upon the companies as to
overpass the bounds of reason.
The decree should be affirmed, and it is so ordered.
Affirmed.
MR. JUSTICE STONE took no part in the determination or decision
of this case.
*
"This account shall include the difference between (a) the
amount of money actually paid (or the current money value of any
consideration other than money exchanged) for telephone plant
acquired, plus preliminary expenses incurred in connection with the
acquisition, and (b) the original cost (note instruction 3-S. 1) of
such plant, governmental franchises and similar rights acquired,
less the amounts of reserve requirements for depreciation and
amortization of the property acquired, and amounts of contributions
to the predecessor company or companies for construction and
acquisition of such property. If the actual original cost is not
known, the entries in this account shall be based upon an estimate
of such cost."
