This is a petition for review of an Interstate Commerce Commission (ICC) order brought by the Illinois Terminal Railroad Company. It challenges an order of the ICC requiring specific use of "incentive per diem" (IPD) funds received by petitioner from other railroads as rental for its boxcars. In 1966 Congress authorized the ICC to establish incentive per diem rates to be charged on certain railroad car rentals. See 49 U.S.C. § 1(14)(a) (1966). The legislation arose from the long history of a national boxcar shortage. Since under the prior rate-setting system it was often cheaper for railroads to rent cars than to own them, the IPD charges were intended to encourage purchasing, building, or rebuilding of boxcars.1

Pursuant to § 1(14)(a), the ICC promulgated an order determining the IPD rates; the duration of the charges (initially only during peak use periods (6 of the 12 months), but in 1973, during the Russian wheat sales, extended to cover the entire year); and that the IPD income had to be "earmarked" and segregated into a fund which could be drawn on by the owner railroad, under certain conditions, to purchase, rebuild, or maintain the cars.2

The IPD receipts are considered as gross income for federal income tax purposes and must be reported as such by creditor-railroads. Since the IPD receipts are subject to federal income tax, the ICC ruled that only IPD amounts received less taxes created and paid as a result of IPD revenue are to be earmarked. 49 C.R.F. § 1036.3.

Illinois Terminal Railroad Co. has paid into the IPD fund incentive amounts received for rental of its cars. Between 1962-65 and 1967-69 petitioner suffered net operating losses (NOL) which, under Int.Rev.Code of 1954, § 172(b) (1)(C), can be carried forward and offset against future income for seven years. In the years 1970-73, petitioner had income of $3,060,510 for federal income tax purposes, and $2,664,321 for ICC reporting purposes. Of the latter figure, $1,295,910 was directly attributable to IPD receipts. In the later years, petitioner utilized its NOL carry forward cancelling all tax liability on its current year's income, including income from IPD receipts. Thus, there was no reduction of earmarked IPD amounts due to federal income tax payments. Petitioner, however, reported a transfer of $673,958.48 from its IPD account to general corporate funds. That amount represented the income taxes which properly would have been charged to the IPD funds had no NOL carryover been available. The ICC Bureau of Accounts disallowed the transfer. On petition for modification of that order the Commission affirmed the reimbursement order finding that the deduction from the IPD account for income taxes not payable because of petitioner's NOL carryover, did not come within the meaning of a deduction for income taxes paid. Ex Parte No. 252 (Sub-No. 1) (Feb. 10, 1975).

The railroad in its petition for review urges that the ICC lacks statutory authorization to require earmarking of IPD funds. Alternatively, it contends that, if the Commission has the power to require earmarking, the order depriving them of the deduction for NOL carryover benefits from IPD funds violates the statute, ICC regulations, and petitioner's constitutional rights.

The statute in question, § 1(14)(a) of the Interstate Commerce Act, reads:

The Commission may, after hearing, on a complaint or upon its own initiative without complaint, establish reasonable rules, regulations, and practices with respect to car service by common carriers by railroad subject to this chapter, including the compensation to be paid and other terms of any contract, agreement, or arrangement for the use of any locomotive, car, or other vehicle not owned by the carrier using it (and whether or not owned by another carrier), and the penalties or other sanctions for nonobservance of such rules, regulations, or practices. In fixing such compensation to be paid for the use of any type of freight car, the Commission shall give consideration to the national level of ownership of such type of freight car and to other factors affecting the adequacy of the national freight car supply, and shall, on the basis of such consideration, determine whether compensation should be computed solely on the basis of elements of ownership expense involved in owning and maintaining such type of freight car, including a fair return on value, or whether such compensation should be increased by such incentive element or elements of compensation as in the Commission's judgment will provide just and reasonable compensation to freight car owners, contribute to sound car service practices (including efficient utilization and distribution of cars), and encourage the acquisition and maintenance of a car supply adequate to meet the needs of commerce and the national defense. The Commission shall not make any incentive element applicable to any type of freight car the supply of which the Commission finds to be adequate and may exempt from the compensation to be paid by any group of carrier such incentive element or elements if the Commission finds it to be in the national interest.

Petitioner argues that Congress, through this statute, authorized the ICC only to encourage car ownership through the use of incentive rates and no authority to require earmarking was given. We must disagree. We find the earmarking requirement to be "a legitimate, reasonable, and direct adjunct to the Commission's explicit statutory power" to authorize IPD rates. See United States v. Chesapeake & Ohio Ry., --- U.S. ----, 96 S. Ct. 2318, 49 L. Ed. 2d 14 (1976).4

The Congress has charged the Commission with the task of determining whether the rates proposed by the carriers are "just and reasonable." 49 U.S.C. § 1(5). In fulfilling this obligation, the Commission must assess the proposed rates not only against the backdrop of the National Transportation Policy, 54 Stat. 897, 49 U.S.C. preceding § 1, but also with specific reference to the statutory criteria set forth by the Congress to guide the ratesetting process. These provisions, in short, require the Commission to ensure that the rate imposed on the traveling or the shipping public will support both an economically sound and efficient rail transportation system.

These same principles must guide the Commission in establishing the incentive per diem rates under § 1(14)(a). The background leading to Congressional approval of the IPD rates is well-known. The opinion of Judge Prettyman in Palmer v. United States, 75 F. Supp. 63 (D.D.C.1947), pointed out that an incentive rate is "regulatory," not "compensatory," and found no authority for such a rate under the pre-1966 statute. The 1966 amendment cured that problem by expressly allowing the Commission to consider the national level of ownership and other factors in determining "whether compensation should be computed solely on the basis of elements of ownership expense . . . or whether such compensation should be increased by such incentive element or elements of compensation as in the Commission's judgment will provide just and reasonable compensation to freight car owners, contribute to sound car service practices . . . and encourage the acquisition and maintenance of a car supply. . . ." 49 U.S.C. § 1(14)(a) (1966). Under the statute, before the Commission can establish a rule, regulation, or practice aimed at alleviating car shortage it must investigate and find that there is indeed an inadequate car supply. See United States v. Allegheny-Ludlum Steel Corp., 406 U.S. 742, 92 S. Ct. 1941, 32 L. Ed. 2d 453 (1971). Section 1(14)(a) expressly states that the Commission cannot make an incentive element applicable to any type of car where it finds the supply adequate. Thus, it is obvious that the IPD charges are regulatory and not compensatory. The IPD income represents compensation above and beyond the base costs of freight car ownership. Under these circumstances the adjunct power to earmark such funds for a specific use, insuring that there will not be "profiteering" as Judge Prettyman feared,5 is implicit in the Congressional mandate authorizing use of the IPD charge when necessary to alleviate the shortage.6

Analogous to the Supreme Court holding in Chesapeake, we find the Commission's order requiring earmarking of IPD funds directly related to the reasonableness of the use of incentive rates. It is the authorized means to accomplish the end sought. As the Court observed in Fla. E. Coast Ry. v. United States, 368 F. Supp. 1009, 1017 (M.D.Fla.1973), "the earmarking of funds provision of the ICC regulation, which provides the heart and soul of the entire plan, is also rationally supported as a method helping to alleviate the shortage." (Emphasis added).

Further support for the Commission's earmarking order can be found in the express authority given the ICC to "establish reasonable rules, regulations, and practices with respect to car service," 49 U.S.C. § 1(14)(a), in light of the definition of "car service" in 49 U.S.C. § 1(10) to include car supply.7

We turn now to the railroad's attack on the Commission's ruling regarding its NOL deduction offsetting IPD earnings during 1970-73. The Commission gave early notice that the earmarked IPD accounts could be reduced for any increase in taxes resulting from incentive per diem earnings so that general corporate funds would not have to be depleted. 343 I.C.C. 49, 65 (1973). By reason of petitioner's NOL carry-forward its IPD income during 1970-73 was offset and no tax was paid on the IPD funds. The railroad claims that this use will cause early exhaustion of its NOL resulting in increased income tax liability in future years. Thus, petitioner argues, it is being denied the benefit of its NOL deduction without receiving any benefit in return, thereby receiving arbitrary and unequal treatment. We do not agree.

The regulation provides, in part: "The earmarked funds shall be reduced by the amount of the additional income tax paid as the result of increasing taxable income by inclusion of net incentive per diem earnings." 49 C.F.R. § 1036.3 (emphasis added). The language is clear, a deduction is permitted for taxes paid. The purpose of the provision is to prevent a reduction in the general corporate account because of increased tax liability created by IPD income. IPD funds are to be reduced to cover for general corporate funds expended. When no taxes are paid there is no reduction in funds in the general corporate account.

Here the railroad offset IPD income for the years 1970-73 with deductions for NOL carryovers, thus avoiding paying any taxes. The savings to the railroad can be used by them for investment in its own car fleet. Avoidance of taxes on IPD income through the use of NOLs is not equivalent to the payment of taxes on IPD income with general corporate funds, within the meaning of the regulation.8

Furthermore, petitioner's claim that the application of its NOL carryovers against IPD income, causing early exhaustion of its NOL and increased income tax liability in future years, violates its Fifth Amendment right to be justly compensated for the taking of its property is not well-founded. The government concedes that the taxpayer cannot be arbitrarily deprived of this property right. However, even assuming petitioner would earn sufficient taxable income to make use of the NOL carryovers in the future, an assumption which petitioner itself conceded to be unlikely, no arbitrary taking of property will result. Under the Commission's ruling, as the government observes, petitioner will be permitted "to reduce its IPD account to the extent that (the) carrier is forced to pay taxes in future years which could have been avoided but for the use of NOL carryovers to offset IPD income." Joint Brief of United States and Interstate Commerce Commission at 28.

Given the validity of the earmarking provision and the IPD program's objective of augmenting the national car fleet, the Commission's treatment of the taxation of IPD income is just and reasonable.

The order of ICC is affirmed.
