tially argues that the affidavits submitted by French and Myers sufficed to defeat a motion for summary judgment. This argument, however, was considered, and in our view properly rejected by the district court. Consequently, Mays’ appeal was frivolous within the meaning of Federal Rule of Appellate Procedure 38.
Having determined that petitioner’s appeal was frivolous, we must next determine whether sanctions are appropriate in this case. Sanctions are appropriate if “the appeal was prosecuted with no reasonable expectation of altering the district court’s judgment and for purposes of delay or harassment or sheer obstinacy.” Reid v. United States, 715 F.2d 1148, 1155 (7th Cir.1983). Moreover, Rule 38 sanctions may be assessed against either an appellant or an appellant’s attorney. See Hill v. Norfolk and Western Ry. Co., 814 F.2d 1192, 1201 (7th Cir.1987).
In this case, the district court’s opinion cogently explained why plaintiff’s affidavits were not sufficient to defeat a motion for summary judgment. Given the incisive nature of the district court’s opinion, appellant’s attorney could not have had a reasonable expectation that the same arguments would prevail in this court and merely delayed the inevitable by filing this appeal. Consequently, we find that Rule 38 sanctions are appropriate in this case.
Finally, we must determine what sanctions to impose and against whom. Rule 38 serves two purposes. First, it compensates victorious parties in the district court for the expense and delay of defending against meritless arguments in the court of appeals. Second, it attempts to deter mer-itless appeals and preserve the appellate court calendar for cases worthy of consideration. Ruderer v. Fines, 614 F.2d 1128, 1132 (7th Cir.1980) (per curiam). After evaluating plaintiff’s appeal with these considerations in mind we conclude that the most appropriate sanction in this case is to assess the costs of this appeal against appellant’s attorney. Accordingly, appellees are ordered to file with this court within fifteen days of the date of this opinion a statement of the costs they incurred in defending the appeal of the district court’s grant of summary judgment.

We also believe that statements contained in appellant’s brief violate Rule 11 of the Federal Rules of Civil Procedure and thus warrant the imposition of sanctions pursuant to Rule 46(c) of the Federal Rules of Appellate Procedure. Rule 11 provides in pertinent part:
Every pleading, motion, and other paper of a party represented by an attorney shall be signed by at least one attorney of record in the attorney’s individual name.... The signature of an attorney or party constitutes a certificate by the signer that the signer has read the pleading, motion or other paper; that to the best of the signer’s knowledge, information, and belief formed after reasonable inquiry it is well grounded in fact and is warranted by existing law or a good faith argument for the extension, modification, or reversal of existing law, and that it is not interposed for any improper purpose, such as to harass or to cause unnecessary delay or needless increase in the cost of litigation.... If a pleading, motion, or other paper is signed in violation of this rule, the court, upon motion or its own initiative, shall impose upon the person who signed it, a represented party, or both an appropriate sanction. ...
Although Rule 11 “is not incorporated by reference or otherwise in any rule of this court, its requirements help to define conduct becoming a member of the bar [under Federal Rule of Appellate Procedure 46].” In Re Kelly, 808 F.2d 549, 551 (7th Cir.1986). Accordingly, Federal Rule of Appellate Procedure 46 authorizes this court to impose sanctions on an attorney whose conduct violates Rule 11.3
In arguing that summary judgment in favor of the Union was improperly granted, appellant’s brief states: “The union, in fact, has been cited by this court for its disgraceful hiring and employment

Rule 46(c) of the Federal Rules of Appellate Procedure provides in pertinent part: In this case, the brief submitted by the Union requested sanctions based on the misrepresentations contained in appellant’s brief. Therefore, appellant’s counsel was on notice that disciplinary action might be forthcoming. Appellant's counsel was afforded the opportunity to explain why he should not be sanctioned for the statements in his brief at oral argument where we repeatedly questioned him about the veracity of these statements. Finally, appellant's counsel did not request a hearing on possible sanctions. Consequently, Rule 46 sanctions may be imposed in this case.
