Katherine A. Zotos appeals from the district court’s grant of summary judgment on her age discrimination claims under the Age Discrimination in Employment Act (ADEA), 29 U.S.C. §§ 621-34, in favor of the Lindbergh School District and two school officials (collectively referred to as District). She also appeals from the district court’s order granting in part the District’s bill of costs. We affirm the district court’s order granting summary judgment. As to the order regarding costs, we affirm the award of costs as hereinafter modified.
Zotos, who was born in 1937, began working as a primary school teacher in the District in 1965. In 1985, Zotos began teaching in the District’s program for gifted and talented students. On March 27,1990, she was notified that she was being transferred from the program into a regular classroom. On July 19, 1990, Zotos filed a charge of age discrimination relating to the transfer with the Equal Employment Opportunity Commission (EEOC). By letter dated November 14, 1990, the EEOC informed Zotos that she had to file suit within two years of the alleged discrimination, or three years in eases of a willful violation.
In March 1991, Zotos was transferred back to the gifted program, but two weeks later she was assigned to a third grade class. By letter dated June 21, 1991, Zotos informed the district that she was exercising her right to take early retirement effective July 1, 1991. She then filed a second age discrimination charge with the EEOC, asserting a constructive discharge. By letter dated January 23, 1992, the EEOC issued a right-to-sue letter. In relevant part the letter stated:
A lawsuit under the [ADEA] ordinarily must be filed within two years of the date of the discrimination alleged in the charge. On November 21, 1991, the ADEA was amended to eliminate this 2 year limit. An ADEA lawsuit must now be filed any time from 60 days after a charge is filed until 90 days after receipt of notice that EEOC has completed action on the charge. Because it is not clear whether this amendment applies to *360 instances of alleged discrimination occurring before November 21, 1991, a lawsuit should be brought within two years of the date of the alleged discrimination and within 90 days of receipt of notice that EEOC has completed action on your charge, whichever is earlier, in order to assure your right to sue.
Emphasis in original.
On June 26, 1992, Zotos filed a complaint in the district court, asserting her transfer and alleged constructive discharge violated the ADEA; she also asserted pendent state law claims. In an amended answer, among other things, the District asserted that Zotos’ “claims are barred by the applicable statutes of limitations.” In a summary judgment motion, the District argued that Zotos’ transfer claim was barred by the two-year statute of limitations of the pre-amended ADEA and that her retirement was voluntary and did not constitute a constructive discharge. Zotos, among other things, responded that her transfer claim was timely because it fell within the three-year limitations period for willful violations.
On October 3, 1995, the district court notified the parties that in order to resolve the statute of limitations issue, it needed additional information, including copies of EEOC letters. The court also allowed Zotos to submit an affidavit concerning the dates she had received the EEOC notices. On October 10, 1995, Zotos filed an affidavit stating that she had received the January 23,1992 EEOC letter advising her to file suit within 90 days of receipt of the letter. Athough Zotos could not recall the date of receipt, she noted that she had been out of town until January 28, 1992. Aso on October 10, the District submitted a supplemental memorandum in support of its motion for summary judgment, pointing out that the Eighth Circuit had held that “the [90-day] limitation period from the Civil Rights Act of 1991 applies to cases filed after November 21, 1991, the effective date of the new limitations period, even if the claim accrued before that date.”
Garfield v. J.C. Nichols Real Estate,
On October 11, 1995, relying on
Garfield, Anderson
and
Littell v. Aid Ass’n for Lutherans,
On appeal, Zotos renews her argument that the court improperly raised a statute of limitations issue sua sponte. She notes that Fed.R.Civ.P. 8(c) requires that a statute of limitations defense must be raised in a responsive pleading or it is deemed waived. Zotos acknowledges that in its amended answer the District asserted that her claims were barred by the “applicable statutes of limitations,” but argues that the district court erred in granting leave to amend the answer. We disagree. It is well settled that “leave shall be freely given when justice so requires.” Fed.R.Civ.P. 15(a). “[T]he district court had the discretion ... to grant [the District] leave to amend its answer to include this omitted Rule 8(c) defense.”
Sanders v. Department of the Army,
Zotos next argues that the District failed to plead the defense with sufficient specificity. Her argument is without merit. “[W]hile a limitations defense must ‘be asserted in a responsive pleading,’ it ‘need not be articulated with any rigorous degree of specificity,’ and is ‘sufficiently raised for purposes of Rule 8 by its
bare assertion.’” Daingerfield Island Protective Soc’y v. Babbitt,
Zotos also argues that the District waived application of the 90-day limitation period by relying on the two-year statute of limitations in its memorandum in support of its summary judgment motion. Again, we disagree. In
Garfield,
this court stated that “there is an implied waiver of a defense ... only where a party’s conduct is ‘so consistent with and indicative of an intent to relinquish [the defense] and so clear and unequivocal that no other reasonable explanation of the conduct is possible.’ ”
Garfield,
We also reject Zotos’ argument that the district court was bound to apply the law as briefed by the parties.
See id.
Rather, as the district court explained, a federal court is bound to apply “the law in effect at the time it renders its decision, unless doing so would result in manifest injustice.... ”
Bradley v. School Bd. of City of Richmond,
Zotos argues that even if her discharge claim is untimely under this circuit’s ease law, the precedents are inapplicable to her transfer claim because in the previous cases the EEOC had informed the plaintiffs of the possible application of the 90-day limitations period and this court did not “address the situation where Congress replaces a statute
*362
of limitations with a shorter one that, if applied to a claim filed after the statute became effective, cuts off a plaintiffs right to sue without providing h[er] an opportunity to comply with the new period.”
Vernon v. Cassadaga Valley Cent. Sch. Dist.,
Zotos’ arguments are persuasive. Indeed, the District appears to agree with her that it would be unjust to apply the 90-day limitations period to the transfer claim. District’s Br. at 6 n.4. However, we need not decide these issues or decide the question whether her transfer claim is subject to equitable tolling. It is well settled that we may affirm the district court’s judgment “on any basis supported by the record.”
Sawdon v. Uniroyal Goodrich Tire Co.,
In the district court Zotos argued that her transfer claim was timely filed under the three-year limitations period for willful violations, asserting that the transfer was part of a continuing violation, which culminated in her discharge. Her argument is without merit. Zotos’ transfer was “a discrete, adverse employment action, such as a discharge, layoff, or failure to promote, [and] ‘constitute[d] a completed act at the time it occurred.’”
Gipson v. KAS Snacktime Co.,
A discriminatory act which is not made the basis for a timely charge is the legal equivalent of a discriminatory act which occurred before the statute was passed. It may constitute relevant background evidence in a proceeding in which the status of a current practice is at issue, but separately considered, it is merely an unfortunate event in history which has no present legal consequence.
Gipson,
We also remind Zotos that “although [a] willful act violate[s] the ADEA, that is not the same as a willful violation of the statute.”
Jarvis v. Sauer Sundstrand Co.,
We now turn to Zotos’ challenge regarding the district court’s order awarding certain costs to the District. Although the District requested $17,119.04 in costs, the
*363
court granted $5,145.64 for costs in connection with deposition transcripts ($4690.34), copying medical records ($415.30), and an expert witness fee in connection with a medical examination ($40.00).

Zotos does not contest that “[t]he district court has substantial discretion in awarding costs to a prevailing party under 28 U.S.C. § 1920 ... and Fed.R.Civ.P. 54(d)[,]”
Richmond v. Southwire Co.,
In particular, Zotos challenges the award of costs as to her 1994 deposition and the depositions of Margaret Mills and Vicki Newman. The court found that Zotos’ deposition was “necessarily obtained” for use in the ease, stating that it had reviewed the “deposition in detail in connection with” its ruling on the summary judgment motion.
See Bathke,
Zotos goes on to argue that because the district court did not rely on the depositions of Newman and Mills in ruling on the summary judgment motion and that the depositions were only relevant to her state law claims, the court erred in awarding costs because, as a matter of law, the depositions were not “necessarily obtained” for the case. We disagree. “ ‘[T]he determination of necessity must be made in light of the facts known at the time of the deposition, without regard to intervening developments that later render the deposition unneeded for further use.’”
Barber v. Ruth,
The district court found that at the time the Newman and Mills depositions were taken, they were reasonably necessary. The court noted that Zotos had listed Newman
*364
and Mills. as trial witnesses and that the District had to prepare for trial prior to the court’s order granting summary judgment.
See Manildra,
We also find no abuse of discretion in the district court’s award of costs incurred in 1994 for copying Zotos’ medical records. However, we do find an abuse of discretion in the court’s award of $40.00 in costs in connection with a court-ordered July 24, 1995 medical examination of Zotos, which the District had requested on July 11, 1995, several months after our decisions in Anderson and Garfield. In the facts of this case, we do not believe the costs incurred in connection with the examination were “necessarily obtained” for use in the case.
Accordingly, we affirm the district court’s order granting summary judgment in favor of the District. The award of costs is hereby reduced by $40.00 and as so modified is affirmed.
