delivered the opinion of the Court.
This case presents the claim that the Maritime Commission exceeded its statutory authority under § 5 of the Merchant Ship Sales Act of 1946, 60 Stat. 43, as amended, 50 U. S. C. App. § 1738, by
(1) including in its contract with petitioners 1 for the bareboat charter of ships a sliding scale that required payment to the Government of more than 50% of certain excess profits and
(2) using the threat of termination of the charter arrangement to compel agreement to divide the calendar year 1947 into separate periods for the purpose of computing such profits.
I.
The Merchant Marine Act, 1936, 49 Stat. 1985, as amended, 46 U. S. C. §§ 1101-1294, provided for the charter of government vessels by the Maritime Commission to private enterprise. Section 709 (a) of that Act, 49 Stat. 2010, incorporated by reference in the 1946 Act, § 5 (c), 60 Stat. 43, provided:
“Every charter made by the Commission pursuant to the provisions of this title shall provide that whenever, at the end of any calendar year subsequent to the execution of such charter, the cumulative net voyage profits (after payment of the charter hire reserved in the charter and payment of the charterer’s fair and reasonable overhead expenses applicable to operation of the chartered vessels) shall exceed 10 per centum per annum on the charterer’s capital necessarily employed in the business of such chartered vessels, the charterer shall pay over to the Commission, as additional charter hire, one-half of such cumulative net voyage profit in excess of 10 per centum per annum: Provided, That the cumulative net profit so accounted for shall not be includedin any calculation of cumulative net profit in subsequent years.”
During World War II, operations of the private merchant marine were disrupted and its fleets reduced by losses and requisition. Meanwhile many vessels were constructed for government operations. Congress by means of the Merchant Ship Sales Act of 1946, supra, sought to ensure postwar rehabilitation of the private merchant marine by having the Maritime Commission sell or charter surplus war-built government vessels. The Commission was instructed “so far as practicable and consistent with the policies of this Act, [to] give preference to . . . applicants to purchase” over applicants to charter. 3 Section 5 (b), 60 Stat. 43, of the Act set out standards for the Commission to follow in chartering vessels:
“The charter hire for any vessel chartered under the provisions of this section shall be fixed by the Commission at such rate as the Commission determines to be consistent with the policies of this Act, but, except upon the affirmative vote of not less than four members of the Commission, such rate shall not be less than 15 per centum per annum of the statutory sales price (computed as of the date of charter). . . . [R]ates of charter hire fixed by the Commission on any war-built vessel which differ from the rate specified in this subsection shall not be less than the prevailing world market charter rates for similar vessels for similar use as determined by the Commission.”
As already indicated, § 5 (c) made the provisions of § 709 (a) of the Merchant Marine Act applicable to charters under the 1946 Act.
The Commission adopted a standard Ship Sales Act charter (“SHIPSALESDEMISE 303”) incorporating these provisions, and Eastern chartered 10 vessels under such a contract dated October 1,1946. Market conditions allowed high profits to be earned in the first eight months of 1947. The Commission decided to terminate existing charters, as it was privileged to do under the contract on 15 days’ notice, but agreed not to terminate if a charterer accepted an Addendum to its contract providing, among other things, for a separate calculation of profit-sharing
Eastern did not attempt to litigate its rights under the 1946 Act until it had completed all the payments required by the charter agreement. In 1955 it filed this
in personam
libel for recovery of money paid pursuant to the profit-sharing provisions and the 1947 “Foreign Trade Addendum.” It asserted that § 709 (a) sets a maximum as well as a minimum rate of profit sharing and precluded the Commission from altering that rate under § 5 (b). It claimed further that, even if such power existed, the Commission’s apparent reliance on § 709 (a) rather than § 5 (b) renders these charter provisions nugatory. Finally, it argued that the 1947 Addendum conflicted with the statutory mandate of § 709 (a) for calendar year accounting of statutory profits, and that the Commission abused its termination privilege by threatening to terminate the charter agreements of those refusing to accept the split-year profit-sharing arrangement. All of these contentions were rejected by the lower court, the Court of Appeals affirming the District Court,
Preliminarily we observe that in the view we take of that case we find it unnecessary to consider the Government’s alternative ground for affirmance: that the doctrine of waiver precludes Eastern from challenging the terms of its charter agreement because once having signed the agreement and benefited from the charter, Eastern cannot seek to overturn provisions of the contract that it regards as unfavorable. 4
The basic statutory question is whether the Commission, in light of § 709 (a), had authority under § 5 (b) to impose the sliding scale of additional hire, and, if so, whether its failure to articulate the particular statutory basis for its action vitiates the validity of the profit-sharing terms of the rate set. We approach this problem with three general interpretative guides, all of which point in the Government’s favor. Some weight is due to the consistent interpretation of the Maritime Commission, the agency entrusted with administration of the statute. See,
e. g., United States
v.
Zucca,
Further, in light of the congressional policy to encourage the sale of ships, contained in § 7 (a) of the 1946 Act, supra, there is an initial presumption that Congress intended that the Commission should have power to establish chartering terms commensurate with making more attractive purchase, instead of charter, of government vessels by private shipowners. Needless to say, these “interpretative aids,” neither singly nor in conjunction, could lead to an affirmance here if it were clear that the Commission’s action contradicted the requirements of the Merchant Ship Sales Act of 1946. However, they are consistent with, and lend support to, what we believe to be the most sensible view of the statutory framework.
According to § 709 (a) of the 1936 Act, as adopted by the 1946 statute:
“The charterer shall pay over to the Commission, as additional charter hire, one-half of such cumulative net voyage profit in excess of 10 per centum per annum . . . .” (Emphasis added.)
Section 5 (b) of the 1946 Act provides:
“The charter hire . . . shall be fixed by the Commission at such rate as the Commission determines to be consistent with the policies of this Act, but,... such rate shall not be less than 15 per centum per annum of the statutory sales price . . . .”
The position that § 709 (a) is the exclusive profit-sharing provision, that it prohibits what might otherwise be sustained as a proper exercise of power under § 5 (b), is somewhat more arguable. Eastern asserts that § 709 (a) was written as a maximum as well as minimum standard for the Commission’s share of excess profits and that its import was not altered by its adoption in the 1946 Act. Significance is placed on Congress’ use of the word “shall,” rather than a phrase such as “not less than,” in fixing the charterer’s obligation to pay 50% of its excess profits.
However, when § 709 (a) was passed, rates of charter hire were determined in most situations, under § 707 (a), 49 Stat. 2009, by competitive bidding in individual cases.

First, it may be noted that “shall” plainly denotes a minimum; one cannot pay 50% and at the same time pay less than 50%. On the other hand, the word does not of linguistic necessity denote a maximum; one can pay 50% and also pay 25% more. While, in recognizing this, we do not mean to suggest that standing alone the 50% standard of § 709 (a) would not be read as establishing a maximum as well as a minimum, it is significant that the section’s language is not inconsistent with a conclusion that higher percentages are permissible. Congress cannot be expected always to be absolutely precise in its statutory formulations. When it brings forward into a new enactment provisions drafted in a different statutory context and in response to other circumstances and policies, the likelihood of imprecision is increased. In light of the great breadth of discretion apparently given to the Commission under § 5 (b) and the expressed concern of Congress that charter rates not
We conclude, therefore, that the Commission had the power under § 5 (b) to impose the sliding scale and that § 709 (a) does not negate that authority. In passing, it may be noted that in addition to the courts below, four other lower courts have reached or assumed the same conclusion. See
Dichman, Wright & Pugh, Inc.,
v.
United States,
We next turn to the question whether § 5 (b) suffices to support the sliding scale for profit-sharing rentals adopted by the Commission, in the face of the assertion
No doubt is cast on the conclusion of the District Court by anything in § 5 (b) or § 709 (a). Section 5 (b) does not require a hearing or any particular kind of procedure (except when the rate is set below 15% of the sales price). Since § 709 (a) does not itself authorize deviations from the 50% rate on excess profits, that section provides, of course, no criteria for assessing the propriety of any such deviation. Section 5 (b) rates are supposed to be fixed “consistent with the policies of this Act” and (at least if lower than 15% of the statutory sales price) are not to be set at less than the prevailing world market charter rates. Since it is plain that the Commission instituted rates it believed to be consistent with the policies of the 1946 Act, it seems patently clear that its determination would have in no way varied had it paid particular attention to § 5 (b) in establishing the sliding scale.
In light of these factors we find inapposite here cases refusing to validate an exercise of administrative discre
tion
Eastern claims that if the sliding-scale charge is proper under § 5 (b), the Commission has not followed the statutory scheme for accounting. Section 709 (a) provides for equal division of profits after payment of the “charter hire reserved in the charter . . . .” Eastern equates this language with the “charter hire . . . fixed by the Commission” under § 5 (b). Without attempting the impossible task of reading into the charter contract the following method of accounting, Eastern argues that this procedure is required by the statute: In addition to the required percent of the statutory sales price, the “charter hire reserved in the charter” includes any charge above 50% of profits; after these charges are computed, the Commission is entitled to 50% of remaining excess profits. How this method would work is most easily seen if we hypothesize an attempt by the Commission to acquire 100% of all excess profits. Instead of achieving this goal, the Commission would have to compute the fixed hire plus 50% of the profits (the amount of charge above the 50% set by § 709 (a)). The Commission would then receive 50% of the remaining profits; as a consequence the
We are not compelled to accept this anomalous result. It is not necessary to read the reference in § 709 (a) to “charter hire reserved in the charter” as synonymous with “charter hire . . . fixed by the Commission” in § 5 (b). It is highly doubtful that the draftsmen intended such a result, particularly since § 709 (a) was brought forward without any attempt to spell out carefully its relationship to § 5 (b). A reading which does greater justice to the whole statutory framework is to limit “charter hire reserved in the charter” to any firm rather than contingent hire, regardless of whether § 5 (b) is'the source for imposing the hire. Even if Eastern’s interpretation of the language were acceptable, however, we see no reason why the Commission cannot reach under § 5 (b) what it would otherwise be paid under § 709 (a). If the sliding scale requires 90% of certain profits to be turned over to the Commission, it makes better sense to say that the Commission can take the full 90% under § 5 (b), thus rendering § 709 (a) superfluous, than to conclude that the Commission’s authority under § 5 (b) extends only to the incremental amount. According to Eastern’s argument § 709 (a) performs a dual function; it allocates that percent of profits which may be reached as “charter hire . . . fixed by the Commission” and it distributes the remaining profits. We think it clear that it was not intended in the context of the 1946 Act to perform the former role; therefore, even were any rate set under
III.
Because of the discouragement of sales resulting from the high profits earned by charterers in the first part of 1947, the Commission sent telegrams to Eastern and other charterers on August 15 informing them of the Commission’s intention to terminate the charter contracts, a privilege given to both parties under clause 14. The telegrams stated that the charterers would be able to continue use of the vessels if they agreed to new terms and conditions. On August 20, the Commission set out the new terms, including a provision that payment of additional charter hire under clause 13 be computed separately for voyages commencing'after September 1. Eastern agreed to the terms ysinte it suffered losses for its post-August voyages, it was required to pay to the Commission a greater amount than would have been the case had 1947 been treated as a unit for accounting purposes. Eastern claims that the “Foreign Trade Addendum” to its charter was invalid insofar as it purported to divide 1947 into two accounting periods. It argues that § 709 (a) required calendar year accounting, that agreement to the Addendum was insufficient to create a new charter contract, and that the Commission could not use its termination power to accomplish an improper result.
We find this position untenable. There was no explicit limitation on the Commission’s power to terminate existing charters, nor do we read § 709 (a), which provides for computation of"additional charter hire “at the end of any calendar year,” as indirectly imposing such

Notes
Hereafter “Eastern:
Compare the opinion below,
§ 7 (a), 60 Stat. 44, 50 U. S. C. App. § 1740.
The Government does not press the claims here that Eastern cannot recover because of the running of the statute of limitations or because of voluntary payments made to the Commission. It asserts that these defenses were pleaded below but were not considered during the hearing; it reserves the right to raise them on remand in the event of a reversal.
See 61 Stat. 190, 191; 62 Stat. 38; 63 Stat. 9; 63 Stat. 349. In 1950, Congress abolished the Maritime Commission and the function of chartering ships was transferred to the Secretary of Commerce, 64 Stat. 308; 64 Stat. 1276, 1277.
Hearings before the Subcommittee on Ship Sales, Charters, and Lay-ups, House Committee on Merchant Marine and Fisheries, 80th Cong., 1st Sess. (1947).
Section 714 of the 1936 Act, 49 Stat. 2011, as amended, 46 U. S. C. § 1204, does provide for negotiated rates of charter hire if essential trade routes cannot otherwise be successfully developed. It contains a firm minimum rate. Had this been the primary method of chartering envisioned in 1936, the section's similarity to § 5 (b) of the 1946 Act would have considerable bearing on any interpretation of the relevance of § 709 (a) in the later Act. The exception this provi sion makes to competitive bidding, however, does not alter the fact that the basic method of rate setting was entirely different under the 1936 Act from that contemplated in 1946. We intimate no view as to the relationship between § 714 and § 709 (a) under the 1936 Act.
Eastern’s contention that the legislative history of the 1946 Act confirms its position is not well taken. That Congress did not disapprove of charters and that it provided separate safeguards to encourage sales does not undermine the plainly expressed preference of sales to charters and the concern that charter rates not be so low as to make purchase less profitable than hire. That some legislators believed the 15% rate of § 5 (b) to be high is irrelevant, since the Commission’s power to raise rates under § 5 (b) is undisputed and the issue here concerns only the kind of rate structure permissible. Finally, the circumscription of Commission discretion, which Eastern believes was intended by Congress, had to do with the desirability of having set rates instead of individually negotiated charters, rather than with the kinds of rates that might be set.
