STAHL, Circuit Judge.

On September 18, 1990, a federal grand jury returned a multiple count indictment against defendant-appellant J. Edward McHugh, a former senior vice-president and loan officer of the Cambridgeport Savings Bank ("CSB"), and defendant-appellant James F. Brennan, a borrower of large sums of money from CSB. The indictment charged both defendants with one count of conspiracy to commit bank fraud and to willfully misapply bank funds; McHugh with one count of bank fraud, six counts of willful misapplication of bank funds, and four counts of making false entries in bank records; and Brennan with two counts of making false statements to a lending institution, one count of aiding and abetting McHugh's bank fraud, and six counts of aiding and abetting McHugh's willful misapplication of bank funds. After a twenty-day trial, a jury returned verdicts of guilty against both defendants on most of the counts. It did, however, acquit McHugh on two counts of willful misapplication and Brennan on one count of aiding and abetting a willful misapplication of bank funds.

Following the verdict, the trial judge issued a comprehensive, twenty-seven page memorandum and order denying Brennan's pending motion for acquittal on all counts charged, but granting McHugh's pending motion for acquittal insofar as it related to the four counts for making false entries in bank records. After a two-day sentencing hearing, Brennan was sentenced to forty-one months in prison and McHugh was sentenced to a year and a day in prison.

On appeal, McHugh and Brennan raise a host of challenges to the trial proceedings. Their complaints can be loosely divided into two categories: (1) there was insufficient evidence to support certain of their convictions, and (2) a number of decisions of the trial judge regarding the parameters of the trial, the admissibility of certain disputed evidence, and the jury instructions constituted reversible error. Brennan also advances miscellaneous arguments that he was victimized by constitutionally infirm legal representation at trial and that his sentence was unlawful. After carefully reviewing the voluminous record in the light of appellants' contentions, we affirm.

I. BACKGROUND

Because attempting to recount the evidence in this case would be both unnecessary and inherently Sisyphean, we cut to the heart of the matter. McHugh was hired by CSB on May 24, 1987, as a senior vice-president and senior loan officer in charge of commercial lending. At the time of McHugh's hiring, CSB had a relatively small commercial lending department. Among other things, McHugh was charged with increasing the volume of commercial loans. To that end, CSB's Board of Investment ("the Board") provided McHugh with a personal lending authority of up to $500,000 per borrower. Commercial loans in excess of $500,000 to any single borrower could not, however, be made without prior Board approval.

On June 5, 1987, Brennan met with McHugh and requested a $70,000 unsecured loan from CSB. In connection with the requested loan, Brennan provided CSB with a signed Personal Financial Statement ("PFS"). The PFS contained a preamble indicating that the borrower would notify the bank of material changes in his/her financial condition. Evidence introduced at trial revealed that Brennan made statements on his PFS pertaining to his income, real estate holdings, notes payable to others, and contingent liabilities that were false both at the time they were submitted and throughout Brennan's relationship with CSB. McHugh approved the loan and, in accordance with the agreed upon procedures, presented it to the Board. The Board subsequently signed off on it. On the term sheet which was required for each loan made, McHugh noted that the purpose of the $70,000 loan was "[t]o assist in the purchase of stock in Harbor Group, Inc." Evidence suggested, however, that Brennan used the loan to cover overdrafts he had written at the Yankee Bank.

So began a relationship that, throughout the remainder of 1987, led to the extension of nine additional loans by McHugh to Brennan, persons closely affiliated with Brennan, or Brennan-controlled entities. The dates, amounts, and persons/entities who received these subsequent loans we summarize as follows:

1. A July 17, 1987, loan to Brennan for approximately $250,000;

2. A July 20, 1987, loan to Brennan for approximately $100,000;

3. An August 3, 1987, loan to Brennan for approximately $500,000;

4. An August 11, 1987, loan to JoAnn Brennan, the defendant's wife, for approximately $332,000;

5. A September 1, 1987, loan to Charles White, a friend of Brennan, for approximately $400,000;

6. A September 2, 1987, loan to Joseph Hoffman, a business associate of Brennan, for approximately $500,000;

7. A September 22, 1987, loan to the Harbor Group for approximately $500,000;

8. An October 30, 1987, loan to the Harbor Group for approximately $550,000; and

9. A December 31, 1987, loan to Brennan for approximately $225,000.

Evidence at trial revealed that Brennan used the proceeds of many of these loans to pay off debts, both to CSB and elsewhere, rather than for the purposes recorded on the relevant term sheets. The evidence also indicated or tended to indicate (1) that many of Brennan's repayment checks bounced but were redeposited at McHugh's direction; (2) that McHugh did not bring these loans and their interconnected nature to the attention of either the Board or James Keegan, CSB's president; (3) that McHugh took affirmative steps to conceal from others at the bank Brennan's problems repaying the loans; (4) that McHugh exceeded his loan authority in making some of these loans; (5) that McHugh made and structured some of these loans in order to circumvent his lending authority, and so that he would not have to bring them to the Board's attention; (6) that no loan file or term sheet was created for the JoAnn Brennan loan; (7) that the loans to JoAnn Brennan and Charles White were made with little or no inquiry into or knowledge of the named debtors' actual abilities to repay the loans; (8) that McHugh knowingly caused false purposes for the White and Hoffman loans to be recorded on their respective term sheets; (9) that McHugh was aware that JoAnn, Brennan, White, and Hoffman expected James Brennan to repay the loans taken out in their names; (10) that the $550,000 loan to the Harbor Group, which was guaranteed by Brennan, was made to disguise the fact that certain loans to Brennan and Brennan-controlled interests were delinquent; (11) that, with regard to the White loan, McHugh directed that Brennan funds be used to make an overdue interest payment; and (12) that, with regard to the White loan, Brennan furnished CSB with a PFS, purportedly on White's behalf, which was riddled with false statements.

During the first week in March of 1988, Keegan became aware that many of the aforementioned loans were both interconnected and delinquent, ordered internal and external audits, and instructed McHugh to send letters to the named borrowers demanding payment. McHugh was terminated on March 11, 1988. The financial loss to CSB exceeded $2,200,000.

II. DISCUSSION

[11] A. Sufficiency of the Evidence

McHugh argues that there was insufficient evidence to support any of his convictions. Brennan contends that there was insufficient evidence to support his convictions on the counts charging conspiracy and making false statements to a lending institution. As we have noted, after the conclusion of the trial, the district court issued a comprehensive, twenty-seven page memorandum and order which, among other things, responded to these very arguments. The memorandum and order surveyed authority pertinent to each of the defendants' arguments, reviewed the evidence in the manner mandated by the appropriate legal standard, and clearly articulated both its conclusions and its reasons therefore. We have carefully reviewed the record and, having employed a standard of review which mirrors that applied by the district court to defendants' motions for acquittal, see, e.g., United States v. St. Michael's Credit Union, 880 F.2d 579, 584 (1st Cir. 1989) ("[T]he standard of review for a judgment of acquittal notwithstanding the verdict is identical to the test employed to measure the sufficiency of evidence supporting a guilty verdict.") (brackets in original) (quoting McNatt, 813 F.2d at 502), find ourselves in complete agreement with the conclusions reached by the district court. We therefore reject defendants' sufficiency challenges substantially on the basis of the district court's opinion. We pause to address only one issue.

In arguing that there was insufficient evidence to support his convictions for willful misapplication of bank funds arising out of the October 30, 1987, $550,000 loan to the Harbor Group and the loans extended to White, Hoffman, and JoAnn Brennan, McHugh contends that our previous opinion in Gens, see supra note 9, mandates a ruling in his favor. After careful consideration, we do not agree.

In Gens, several bank officers were convicted of willful misapplication under 18 U.S.C. § 656 for making loans to certain individuals while aware that the proceeds would be turned over to a borrower who, because he had reached the bank's lending limit, could not be loaned any more money. In surveying the indictment and charge to the jury in that case, we first determined that the jury had been instructed to find defendants guilty "if it . . . found that [defendants] granted the loans to the named debtors knowing that the proceeds would be turned over to [the off-limits borrower]." Id. at 221. We then reversed the convictions, noting that "such a finding by itself is not sufficient to constitute willful misapplication under § 656." Id. (Emphasis supplied). In so doing, we made clear that "where the named debtor is both financially capable and fully understands that it is his responsibility to repay, a loan to him cannot — absent other circumstances — properly be characterized as sham or dummy [and therefore illegal], even if bank officials know he will turn over the proceeds to a third party." Id. at 222. (Emphasis supplied). Although we did not specifically say so, clearly underpinning our holding was the belief that, without more, a rational factfinder cannot infer an intent to defraud the bank on the part of a bank official who simply makes a loan to a financially capable party who understands his/her repayment obligation. See generally id. at 222-23.

The facts here are considerably different from those in Gens. As we have stated, there was evidence from which a rational jury could have concluded that JoAnn Brennan, White, and Hoffman did not themselves expect to repay CSB. Moreover, there was evidence suggesting that, with regard to the JoAnn Brennan and White loans, McHugh made little or no effort to determine the actual financial capabilities of the named debtors. Thus, with regard to the JoAnn Brennan, White, and Hoffman loans, the jury could have concluded that this was not a situation where, at the time the loans were extended, McHugh knew that the named debtors were both financially capable and fully understood their obligations to repay the loans. See id. at 222.

More importantly, this also is a case where there were "other circumstances," see id., which serve to render the reasoning of Gens inapposite. There was evidence from which the jury could have inferred, among other things, (1) that McHugh knowingly caused false purposes for the loans to Charles White and Joseph Hoffman to be recorded on their respective term sheets; (2) that McHugh failed to follow customary bookkeeping procedures in extending the loan to JoAnn Brennan; (3) that McHugh exceeded his loan authority in making the loan to the Harbor Group; and (4) that the loan to the Harbor Group was made for the purpose of disguising the fact that certain loans to Brennan and Brennan-controlled interests were delinquent. Moreover, there was evidence from which a jury could have found that McHugh structured these loans so that he would not have to present them to the Board for prior approval. In our view, these are precisely the types of circumstances that could have led the jury to conclude that McHugh, in extending these loans, exhibited "a reckless disregard" of CSB's interests. See Cyr, 712 F.2d at 732; Fusaro, 708 F.2d at 21. Accordingly, we decline to upset McHugh's convictions on the misapplication counts.

[17] B. Pretrial and Trial Issues

As we have stated, McHugh and Brennan raise a number of challenges to decisions the district court made regarding the parameters of the trial, the admissibility of certain evidence, and the jury instructions. We discuss each argument in turn.

1. Severance

McHugh contends that the district court committed reversible error in denying his motion for severance. More particularly, McHugh asserts (1) that the number of counts in the indictment created jury confusion; (2) that there was a prejudicial spill-over of evidence, particularly "Rule 404(b) evidence," that was admitted solely against Brennan; and (3) that the defendants were asserting such inconsistent defenses that severance was warranted. We do not agree.

A trial court will grant severance "only upon a strong showing of prejudice." E.g., United States v. Tejeda, 974 F.2d 210, 219 (1st Cir. 1992). A district court's denial of a motion for relief from prejudicial joinder, see Fed.R.Crim.P. 14, is reviewed only for an abuse of discretion, e.g., United States v. Tracy, 989 F.2d 1279, 1283 (1st Cir.), cert. denied ___ U.S. ___, 113 S.Ct. 2393, 124 L.Ed.2d 294 (1993), and we will reverse only if the district court's decision "'deprived defendant of a fair trial, resulting in a miscarriage of justice.'" Tejeda, 974 F.2d at 219 (quoting United States v. McLaughlin, 957 F.2d 12, 18 (1st Cir. 1992)).

Briefly stated, we can perceive no abuse of discretion resulting in a miscarriage of justice here. Although this was a complicated case, McHugh has provided us with absolutely no basis for concluding that the jury was confused. Rather, the discriminating verdict suggests to us that the jury was fully able to follow the court's instructions and differentiate between the counts and defendants. See United States v. Boylan, 898 F.2d 230, 246 (1st Cir.), cert. denied, 498 U.S. 849, 111 S.Ct. 139, 112 L.Ed.2d 106 (1990). Moreover, we are persuaded that the district court's vigilant and persistent use of limiting instructions throughout the trial, when taken with its final charge instructing the jury to consider the defendants and the counts separately, adequately protected McHugh from the possible effects of prejudicial spillover. See Tejeda, 974 F.2d at 219. Finally, to the extent that McHugh raised any defenses that were inconsistent with the ones presented by Brennan, McHugh has not articulated, nor can we discern, how the inconsistencies were "so prejudicial and the defenses so irreconcilable that the jury unjustifiably . . . infer[red] that this conflict alone demonstrates that both are guilty." United States v. Luciano Pacheco, 794 F.2d 7, 8 (1st Cir. 1986) (quoting United States v. Bautista, 731 F.2d 97, 100 (1st Cir. 1984)). Accordingly, we find that the district court did not abuse its discretion in refusing to grant McHugh's severance motion.

2. Evidence Relating to Brennan's Dealings with Other Banks and Persons

Brennan generally argues that "the Government was permitted to introduce excessive evidence relating to other transactions that were not a basis for the indictment." He goes on, however, to specify only three examples of such "excessive" evidence: (1) the testimony of Gloria Campobasso regarding an outstanding promissory note Brennan had given her, (2) the testimony of Donald Moscone regarding an outstanding promissory note Brennan had given him, and (3) the testimony of K. Dun Gifford regarding a certain loan he had taken out at the First American Bank on Brennan's behalf. At trial, Brennan neither objected to the introduction of any of this evidence nor did he request a limiting instruction. Thus, the admission of this evidence can serve as a basis for reversal only if plainly erroneous. Gonzalez-Torres, 980 F.2d at 791. After carefully reviewing the entire record, we discern no plain error in the district court's admission of this evidence. Accordingly, we reject Brennan's argument for reversal on this ground.

3. Gifford's Testimony Characterizing Brennan's Actions Towards Him as "Illegal, Unlawful and Fraudulent"

Brennan's next argument, that K. Dun Gifford's testimony that Brennan's dealings with him were "illegal, unlawful and fraudulent" prejudiced him, suffers a similar fate. Even if we construe the admission, of this statement as erroneous, Brennan's failure to object to it at trial limits our review to the now-familiar plain error rubric. Id. Once again, our review persuades us that the district court's admission of this evidence did not rise to the level of plain error. Accordingly, we decline to reverse on this ground.

4. Prosecutorial Misconduct

Brennan makes two separate arguments that prosecutorial misconduct requires a reversal of his conviction. He first claims that he is entitled to a new trial because the prosecutor asked him on cross-examination, without a good faith basis for the question, whether he was terminated from prior employment as a stockbroker at Tucker, Anthony, and Day. The record reveals, however, that George Downey and Brian O'Rourke, who were interviewed by the Federal Bureau of Investigation prior to trial, stated to the interviewing agents that Brennan had been terminated from his employment at Tucker, Anthony, and Day for unauthorized trading. Brennan has not presented us with any evidence suggesting that the Government knew, or should have known, that these statements were false. Accordingly, there is no reason for us to conclude that the question posed to Brennan on cross-examination was not asked in good faith.

Second, Brennan contends that the Government acted improperly in putting into issue, both in its cross-examination of Brennan and in its rebuttal argument, the fact that Brennan did not introduce into evidence any records corroborating certain aspects of his testimony. In Brennan's view, such actions apparently were tantamount to making a comment on Brennan's failure to testify and thereby shifted the burden of proof from the Government to Brennan. Again, we do not agree.

Without question, clearly it is impermissible for a prosecutor to comment, either directly or by implication, on a defendant's failure to take the stand during a trial. Griffin v. California, 380 U.S. 609, 615, 85 S.Ct. 1229, 1233, 14 L.Ed.2d 106 (1965). However, when a defendant does take the stand, a prosecutor may attack as weak the evidentiary foundation upon which a defendant's testimony rests. See United States v. Garcia, 818 F.2d 136, 143-44 (1st Cir. 1987); United States v. Savarese, 649 F.2d 83, 87 (1st Cir. 1981). Moreover, we previously have held that a prosecutor's comments regarding a defendant's failure to produce documents corroborating a defense theory are proper if they are limited to assailing the strength or plausibility of the proffered theory. See United States v. Glantz, 810 F.2d 316, 321-22 (1st Cir.), cert. denied, 482 U.S. 929, 107 S.Ct. 3214, 96 L.Ed.2d 701 (1987).

Having reviewed the questions and comments at issue here, we are persuaded that they were made solely for the purpose of calling into question the strength and plausibility of certain of Brennan's testimony. Moreover, we are convinced that the jury could not have drawn an improper inference from them. Accordingly, we reject Brennan's request for a new trial insofar as it is based upon these questions and comments.

5. Deposition Testimony of Non-Testifying Codefendant

Brennan also argues that the district court's admission against him, pursuant to Fed.R.Evid. 801(d)(2), of certain deposition testimony given by the non-testifying McHugh during the course of a civil case in 1989 entitles him to a new trial. In Brennan's view, the admission of this material infringed on his Sixth Amendment right to conduct adequate cross-examination of an adverse witness and resulted in reversible error. We do not share Brennan's belief that reversible error was committed.

As an initial matter, we agree with Brennan that because the disputed deposition testimony was not given "during the course and in furtherance of the conspiracy," it was not admissible under Fed.R.Evid. 801(d)(2)(E). See United States v. Carper, 942 F.2d 1298, 1301 (8th Cir.) (statement made to officer after arrest of coconspirator not admissible under Fed.R.Evid. 801(d)(2)(E) because it was not made in furtherance of conspiracy), cert. denied, ___ U.S. ___, 112 S.Ct. 614, 116 L.Ed.2d 636 (1991). However, even if we construe the admission of the statement as erroneous, our review of the entire record persuades us that the error was harmless beyond a reasonable doubt. See Chapman v. California, 386 U.S. 18, 22-24, 87 S.Ct. 824, 826-28, 17 L.Ed.2d 705 (1967); Manocchio v. Moran, 919 F.2d 770, 783-84 (1st Cir. 1990) (subjecting material which creates Sixth Amendment Confrontation Clause problems to harmless error analysis), cert. denied, ___ U.S. ___, 111 S.Ct. 1695, 114 L.Ed.2d 89 (1991); see also Carper, 942 F.2d at 1301-02 (admission of statement to officer under Fed.R.Evid. 801(d)(2)(E) held to be harmless error).

Simply put, we do not believe, as Brennan contends, that McHugh's testimony tended to prove that "Brennan was fabricating the purposes of the loans." McHugh's deposition testimony was that McHugh did not know why Brennan was seeking the loans; it was not that Brennan provided him with false purposes for the loans. Thus, the testimony had little, if any, probative value. This fact, when coupled with the abundance of evidence, completely independent of the material here at issue, to support each of Brennan's convictions, convinces us beyond a reasonable doubt that the jury "would have reached the same verdict without having received the tainted evidence." Clark v. Moran, 942 F.2d 24, 27 (1st Cir. 1991) (quoting Milton v. Wainwright, 407 U.S. 371, 377, 92 S.Ct. 2174, 2178, 33 L.Ed.2d 1 (1972)); see also United States v. Hudson, 970 F.2d 948, 953-54 (1st Cir. 1992) (overwhelming independent evidence of guilt renders erroneous failure to admit certain exculpatory evidence harmless error). Accordingly, we decline Brennan's request for a new trial insofar as it is premised on the allegedly erroneous admission of the McHugh deposition testimony.

6. Jury Instructions

McHugh contends that, in three respects, the district court committed reversible error in its jury instructions. After carefully reviewing the record in light of McHugh's arguments, we do not agree.

a. Ratification of Board as a Defense

McHugh argues that the court erred in refusing to instruct the jury that ratification by the Board constitutes a complete defense to willful misapplication. In so doing, McHugh refers us to several cases which, without analysis, simply state that valid consent or ratification by the Board of Directors is a defense to a charge of misapplication. See, e.g., United States v. Gregory, 730 F.2d 692, 701 (11th Cir. 1984), cert. denied, 469 U.S. 1208, 105 S.Ct. 1170, 1171, 84 L.Ed.2d 321 (1985); United States v. Beran, 546 F.2d 1316, 1321 (8th Cir. 1976), cert. denied, 430 U.S. 916, 97 S.Ct. 1330, 51 L.Ed.2d 595 (1977).

In contrast, courts which recently have had occasion to address the issue specifically have concluded that, absent special circumstances, "knowledge, ratification and consent [of the Board] are not per se defenses to the charge [of willful misapplication]." United States v. Cauble, 706 F.2d 1322, 1353 (5th Cir. 1983) cert. denied, 465 U.S. 1005, 104 S.Ct. 996; 79 L.Ed.2d 229 (1984); see generally Villa, Banking Crimes, § 3.02[5][c]; accord United States v. Bailey, 859 F.2d 1265, 1279 (7th Cir. 1988), cert. denied, 488 U.S. 1010, 109 S.Ct. 796, 102 L.Ed.2d 787 (1989); United States v. Castro, 837 F.2d 441, 442 (11th Cir. 1988). Instead, they have determined that knowledge, ratification, and consent "are evidentiary matters that may be considered as part of the defense that there was either not willful misapplication or not intent to injure the bank." Cauble, 706 F.2d at 1353; see also United States v. Castro, 887 F.2d 988, 995 (9th Cir. 1989). We are in full agreement with the rule established by these courts.

In our view, the correctness of this recent line of authority is best demonstrated by a brief explication of the practical effects of its negation. If we were to adopt the absolute rule proposed by McHugh and hold that ratification by a Board of Directors per se exonerates a bank officer from charges of willful misapplication, then we would, for example, put beyond the reach of § 656 a bank officer who, in collusion with a rogue Board, provides bank funds to an otherwise unqualified personal friend. We simply cannot discern any rational justification for reaching such a result.

In the instant matter, the district court declined to instruct the jury that, as a matter of law, it could not convict McHugh of misapplication if it found that the Board had ratified the loans at issue. Instead, the court allowed McHugh to introduce evidence of ratification and to argue that this evidence suggested that McHugh had no intent to injure or defraud CSB. We believe that, in this case, the court's actions were entirely appropriate. Accordingly, we reject McHugh's claim of reversible error.

b. Reference to False Entries in Overt Act Instructions

McHugh next contends that because the district court entered a judgment of acquittal notwithstanding the verdict for McHugh on the false entry counts, it was reversible error for it to have allowed the jury to consider the incident underlying one of the false entries counts as an overt act in its conspiracy instruction. The error, in McHugh's view, arises from the fact that "the jury may have found [McHugh] guilty of conspiracy solely on the basis of an alleged act which was not criminal." However, it is well established that an overt act need not be a crime. Yates v. United States, 354 U.S. 298, 334, 77 S.Ct. 1064, 1085, 1 L.Ed.2d 1356 (1957), overruled on other grounds, Burks v. United States, 437 U.S. 1, 98 S.Ct. 2141, 57 L.Ed.2d 1 (1978); see also United States v. Medina, 761 F.2d 12, 15 (1st Cir. 1985). Accordingly, McHugh's argument, limited as it is to the statement quoted above, fails as a matter of well-established law.

c. Loan Authority Instruction

McHugh also takes issue with the district court's having instructed the jury: "In addition, with regard to these charges, you may also consider the evidence concerning Mr. McHugh's loan authority and question whether he acted with intent to injure [the CSB] in his dealings with Mr. Brennan." It is McHugh's opinion that this instruction improperly "focused the attention of the jury on resolution of one evidentiary issue as especially significant in their [sic] deliberations [concerning] whether [McHugh] acted with intent to injure and defraud." Our review of the record, however, persuades us that this instruction, far from being faulty, was an altogether proper exercise by the district judge of his authority to "assist the jury in arriving at a just conclusion by explaining and commenting upon the evidence, [and] by drawing their [sic] attention to the parts of it which he thinks important[.]" Querica v. United States, 289 U.S. 466, 469, 53 S.Ct. 698, 699, 77 L.Ed. 1321 (1933). Accordingly, we reject McHugh's characterization of this instruction as erroneous.

C. Miscellany

Brennan raises three final arguments. First, he asserts that his representation at trial and at sentencing was constitutionally deficient. Next, he contends that the district court abused its discretion in sentencing him to the high end of the relevant guideline range. Finally, he maintains that the court abused its discretion in adjusting his sentence upward for obstruction of justice. None of Brennan's arguments requires extended discussion.

1. Ineffective Assistance

Brennan claims that his representation at trial and at sentencing was ineffective and violated his Sixth Amendment rights. In so doing, Brennan points primarily to the failure of trial counsel to introduce certain documents into evidence and the failure of sentencing counsel to spend sufficient time preparing for the sentencing hearing. However, the appellate record does not indicate that either of these claims was properly raised before and/or addressed by the district court. Moreover, our review of the record persuades us that the record is not sufficiently developed for us to address the merits of Brennan's Sixth Amendment claim at this time. Accordingly, we do not reach it. See, e.g., United States v. Gray, 958 F.2d 9, 15 (1st Cir. 1992) ("Time and again we have held that a claim of inadequate representation will not be resolved on direct appeal when the claim has not been raised in the district court, unless the critical facts are not in dispute and a sufficiently developed record exists."); see also United States v. Hoyos-Medina, 878 F.2d 21, 22 (1st Cir. 1989) ("Fairness to the parties and judicial economy both warrant that, absent extraordinary circumstances, an appellate court will not consider an ineffective assistance claim where no endeavor was first made to determine the claim at the district court level.").

2. Sentence at High End of Guidelines Range

Brennan also contends that the district court abused its discretion in sentencing him to the high end of the relevant guideline range while departing downward in sentencing McHugh. The thrust of Brennan's argument is that the disparity between the sentences of McHugh and himself is unfair. Established caselaw, however, makes clear that we have no jurisdiction to review a sentence that is within the applicable guideline range. E.g., United States v. Aubin, 961 F.2d 980, 984 (1st Cir.), cert. denied, ___ U.S. ___, 113 S.Ct. 248, 121 L.Ed.2d 180 (1992). Accordingly, we do not reach the merits of Brennan's argument.

3. Enhancement for Obstruction of Justice

Finally, Brennan asserts that the district court abused its discretion by enhancing his sentence two levels for obstruction of justice for perceived perjurious testimony. See U.S.S.G. § 3C1.1 ("If the defendant willfully obstructed or impeded, or attempted to obstruct or impede, the administration of justice during the investigation, prosecution, or sentencing of the instant offense, increase the offense level by 2 levels.") (1991 version). A district court's application of this guideline provision is reviewable only for clear error. E.g., United States v. Batista-Polanco, 927 F.2d 14, 22 (1st Cir. 1991). Our review convinces us that the district court's application of U.S.S.G. § 3C1.1, far from being clearly erroneous, is amply supported by the record. Accordingly, we reject Brennan's claim that the enhancement at issue was an abuse of discretion.

III. CONCLUSION

Having rejected each of the arguments made on appeal by Brennan and McHugh, we affirm their convictions and sentences.

Affirmed.
