This is an appeal from the judgment of the trial court dismissing the plaintiffs administrative appeal from an interim rate determination of the named defendant, the department of public utility control (department). The department’s decision that is the subject of the present appeal reduced electricity rates through a rate base reduction and amortization of regulatory assets. The outcome of this appeal hinges upon the interpretation of General Statutes § 16-19 (g),1 the [117]*117interim rate decrease statute. The plaintiff, the office of consumer counsel, claims on appeal that the trial court improperly: (1) substituted its judgment for that of the department when it determined that accelerating amortization of regulatory assets directly benefits ratepayers; (2) concluded as a matter oflaw that the interim rate decrease statute does not require a cash rate reduction in the absence of a showing of direct benefit to ratepayers; and (3) permitted amortization of regulatory assets instead of requiring an actual cash decrease in rates as mandated by statute. We disagree and we therefore affirm the judgment of the trial court.
The defendant Connecticut Light and Power Company (power company) is a public utility company regulated by the department. Pursuant to its statutorily mandated duty under General Statutes § 16-19a,2 the [118]*118department conducted a periodic review of the power company in 1997. The periodic review revealed that the power company would likely have substantial oveream-ings. The department, therefore, instituted a two-phase process. The first phase was an interim rate decrease hearing from which a decision was issued on February 25,1998. The second phase consisted of a full rate case, which was concluded on February 5, 1999. The final result of the full rate case is not at issue. In this appeal, only the result of the interim rate decrease hearing is at issue.
The interim rate decrease procedure, which was the procedure undertaken by the department, is set out in § 16-19 (g). Section 16-19 (g) requires the department to conduct a hearing on the need for an interim rate decrease when certain triggering events occur. The impetus for a hearing in this case was the department’s finding at the periodic review that the power company would be overearning by at least $141 million.3 “At the completion of such hearing, the department may order an interim rate decrease if it finds that such return on equity or rates exceed a reasonable rate of return or are more than just, reasonable and adequate as determined by the department. Any such interim rate decrease shall be subject to a customer surcharge if the interim rates collected by the company are less than the rates finally approved by the department or fixed at the conclusion of any appeal taken as a result of any finding by the department. Such surcharge shall be assessed against customers in such amounts and by [119]*119such procedure as ordered by the department.” General Statutes § 16-19 (g).
Pursuant to its mandate under General Statutes § 16-2a,4 the plaintiff participated in the interim rate decrease hearing. Among the department’s considerations at the hearing was the “tenuous” financial condition of the power company5 brought about by its nuclear operations that had cost it more than one billion dollars, which the department had not permitted the power company to collect from its ratepayers. At the close of the interim rate decrease hearing, the department allowed the power company to apply approximately [120]*120$110.5 million of its projected overeamings toward accelerated amortization of certain regulatory assets as part of an interim rate decrease.6 The department also, however, deleted approximately $30.5 million from the rate base that represented Millstone Unit I, resulting in a 1.4 percent cash rate reduction. The plaintiff objected only to the $110.5 million of accelerated amortization. This appeal followed.

We believe that a determination of whether the statutory authority to reduce rates on an interim basis provided by § 16-19 (g) is mandatory or discretionary is determinative of this appeal. We conclude that the statutory direction of § 16-19 (g) is discretionary in nature.
We begin our analysis with the text of the statute. Section 16-19 (g) provides that “[a]t the completion of [the interim rate decrease] hearing, the department may order an interim rate decrease if it finds that such return on equity or rates exceed a reasonable rate of return or are more than just, reasonable and adequate as determined by the department. ...” (Emphasis added.) “It is well established that [i]f . . . language ... is clear and unambiguous, we will interpret it in accordance with its plain meaning absent a compelling reason to the contrary. . . . State v. Angell, 237 Conn. 321, 327, 677 A.2d 912 (1996).” (Internal quotation marks omitted.) Richard Riggio & Sons, Inc. v. Galiette, 46 Conn. App. 63, 66, 698 A.2d 336, cert. denied, 243 Conn. 920, 701 A.2d 343 (1997), cert. denied, 522 U.S. 1115, 118 S. Ct. 1050, 140 L. Ed.2d 113 (1998). The statutory language of § 16-19 (g) is clear: “the department may order an [122]*122interim rate decrease . . . .” (Emphasis added.) “We have consistently held that ‘may’ is directory rather than mandatory. See, e.g., Seals v. Hickey, 186 Conn. 337, 345-47, 441 A.2d 604 (1982). The word ‘may,’ unless the context in which it is employed requires otherwise, ordinarily does not connote a command. Rather, the word generally imports permissive conduct and the conferral of discretion. See id., 345; Ridgeway v. Ridgeway, 180 Conn. 533, 540, 429 A.2d 801 (1980); see also A. Dubreuil & Sons, Inc. v. Lisbon, 215 Conn. 604, 611, 577 A.2d 709 (1990).” Commission on Human Rights & Opportunities v. Truelove & Maclean, Inc., 238 Conn. 337, 349, 680 A.2d 1261 (1996) (statutory language of General Statutes § 46a-86 [b], providing that hearing officer, upon finding discriminatory employment practices, “may order the hiring or reinstatement of employees, with or without back pay,” is discretionary [emphasis added]).
The legislature’s use of the word “shall” in other contexts in § 16-19 (g) further bolsters our interpretation.7 “The use of the word ‘shall’ in conjunction with the word ‘may’ confirms that the legislature ‘acted with complete awareness of their different meanings’; Hartford Principals’ & Supervisors’ Assn. v. Shedd, 202 Conn. 492, 506, 522 A.2d 264 (1987); and that it intended the terms to have different meanings. Hinchliffe v. American Motors Corp., 184 Conn. 607, 613, 440 A.2d 810 (1981) (use of different terms within same sentence of statute ‘plainly’ implies different meanings intended), aff'd, 192 Conn. 252, 470 A.2d 1216 (1984); see also Plourde v. Liburdi, 207 Conn. 412, 416, 540 A.2d 1054 (1988).” Angelsea Productions, Inc. v. Commission on Human Rights & Opportunities, 236 Conn. 681, 694-95, 674 A.2d 1300 (1996). The plain language of the statute [123]*123leaves to the discretion of the department whether to order any interim rate decrease at all.8
We also may consider the regulatory purpose articulated in General Statutes § 16-19e.9 Section 16-19e (a) provides in relevant part that “[i]n the exercise of its powers under the provisions of this title, the Department of Public Utility Control shall examine and regulate . . . the establishment of the level and structure [124]*124of rates in accordance with the following principles ... (4) that the level and structure of rates be sufficient, but no more than sufficient, to allow public service companies to cover their operating and capital costs, to attract needed capital and to maintain their financial integrity, and yet provide appropriate protection to the relevant public interests, both existing and foreseeable . . . .” The discretionary authority whether to decrease rates on an interim basis conforms to the legislative concern that both legitimate business concerns and the public interest be served.10
Finally, we cannot ignore the statutory scheme pursuant to which an interim rate decrease is, as the term suggests, temporary. An interim rate decrease hearing is to be followed by a full rate determination hearing.11 The fact that an interim rate hearing results in only temporary ratemaking until more information is available at a subsequent full rate case hearing indicates that the legislature vested the department with discretion to determine whether an interim rate adjustment was necessary at all. The mandatory surcharge to be levied against ratepayers if the department later determines the interim rate decrease to have been excessive is further evidence of the discretion afforded the department because the department must temper its decision with the consideration of the potential future impact on ratepayers of a temporary rate decrease.
These factors lead to the conclusion that the interim rate decrease authority is discretionary. That determination disposes of the plaintiffs claims, because those claims rest upon the implicit premise that an interim rate decrease is mandatory when a utility is oveream-ing.
[125]*125III
Each of the plaintiffs three specific claims implicitly presupposes that an interim rate reduction is mandatory when there are overearnings by a utility. Our conclusion that such rate reductions are, in fact, discretionary on an interim basis fatally undermines the plaintiffs position. Even if our conclusion were otherwise, however, we would reject the plaintiffs arguments.
A
The plaintiff claims that the trial court improperly concluded that accelerating the amortization of regulatory assets directly benefits ratepayers under § 16-19 (g). As we understand it, the plaintiffs argument is that the trial court improperly affirmed the decision of the department on the basis of a factual determination that the department did not make and that is not supported by the evidence in the record — namely, that the accelerated amortization directly benefits ratepayers under § 16-19 (g).12 We disagree with the plaintiff, because any such finding by the trial court, even if improper, was unnecessary and not dispositive.
Section 16-19 (g) requires that “the company . . . demonstrate to the satisfaction of the department that earning such a return on equity or collecting rates which are more than just, reasonable and adequate is directly beneficial to its customers. ...” (Emphasis added.)
The plaintiffs argument that the trial court improperly discerned a direct benefit to ratepayers miscon-[126]*126straes the statute. The department is not required to justify its action pursuant to § 16-19 (g) as a direct benefit to ratepayers. The “direct benefit” language refers to the utility’s justification for retaining oveream-ings, not to the department’s discretionary authority to order a rate decrease. Moreover, the plaintiffs contention that accelerated amortization must directly benefit ratepayers incorrectly presupposes that the amortization of regulatory assets is not a rate decrease.
Even if we assume that it were necessary to prove that the amortization was directly beneficial to ratepayers, it appears that the amortization does benefit ratepayers by reducing future liabilities as discussed in part III B of this opinion.
B
The plaintiff next claims that the trial court improperly determined as a matter of law that the asset amortizations are actually rate reductions. The plaintiff asserts that the trial court improperly permitted the department to adjust overearnings by writing down the power company’s regulatory assets while allowing it to maintain the same cash flow position. The department and the power company, on the other hand, contend that rate reduction is not synonymous with and does not require reduced cash flow. We agree with the department and the power company.
The accelerated amortization of regulatory assets is a real and tangible rate reduction, albeit less apparent and immediate than a cash rate reduction. A regulatory asset is a liability of a utility’s ratepayers. Utility companies may incur large expenses in various ways — storm damages, installation of new facilities, increased taxes and so forth. These expenses, if passed immediately on to ratepayers, could create havoc. An immediate recovery of such expenses could cause sudden upward increases in rates, commonly termed “rate shock.” In [127]*127order to avoid rate shock, commissions often will permit utility companies to recover their expenses from ratepayers on a deferred basis, listing the ratepayers’ debt as a “regulatory asset.” A regulatory asset is, therefore, a future debt of the ratepayers that can be passed on, together with interest, to the ratepayers. Accelerated amortization of a regulatory asset by the power company, therefore, necessarily reduces the future liability of its ratepayers. See L. Hyman, America’s Electric Utilities: Past, Present and Future (5th Ed. 1994) p. 243; National Conference of State Legislators, The States & Utility Regulation: Electric, Natural Gas, & Telecommunications: Collected Papers (1985).
For the plaintiff to maintain that there is no rate reduction in this instance is misleading. Certainly, there is no immediate cash rate reduction. Ratepayers continue to pay the same rate. Future rates, however, necessarily will be lower because of the write down of the regulatory assets that would constitute future liabilities.
C
The plaintiff finally claims that the trial court improperly determined as a matter of law that § 16-19 (g) does not require a cash rate reduction when the department fails to find a direct benefit to ratepayers. In other words, the plaintiff reads the statute to mandate an immediate cash rate reduction unless the department finds a direct benefit to ratepayers. We disagree.
There is no language in the statute to support this interpretation. Section 16-19 (g) simply provides that the department “may order an interim rate decrease . . . .” (Emphasis added.) Nothing in the text of the statute mandates that a decrease must be a cash reduction; or, as the trial court stated, nothing in the statute precludes a noncash rate adjustment. As discussed earlier, a noncash reduction can be a real and meaningful rate decrease.
[128]*128Moreover, contrary to the plaintiffs assertion, the legislative history of § 16-19 does not support its position. The plaintiff essentially argues that because § lb-19 (d), the interim rate increase statute, allows cash rate increases to utilities, the legislature intended § lb-19 (g) to provide analogous relief to ratepayers and that, therefore, the legislators intended § 16-19 (g) to provide only cash rate decreases. The legislative history of § 16-19 (g), however, indicates only that the legislature, recognizing the existence of a mechanism whereby utilities could petition for and obtain an interim rate increase, sought to provide a mechanism whereby the department could order an interim rate decrease to benefit ratepayers. The legislative history provides no support for the further conclusion that such a decrease must be a cash reduction.
The judgment is affirmed.
In this opinion the other justices concurred.
