U S Wеst Communications, Inc., appeals from the amended judgment entered by the District .Court 2 pursuant to Federal Rule of Civil Procedure 59(e) in favor of James Perkins based on U S West’s Federal Rule of CM Proсedure 68 offer of judgment. We affirm.
On November 19, 1996, U S West moved for summary judgment in this Title VII sex discrimination case. ■ On March 18, 1997, while the summary judgment motion was pending and in the absence of a trial date, U S West made a Rule 68 offer of judgment. 3 Two days-later, on March 20, 1997, the District Court, having no knowledge of U S West’s offer of judgment, granted summary judgment in favor of U S West and dismissed Perkins’s complaint. On March 21, 1997, counsel for Perkins, having learned оf the District Court’s adverse grant of summary judgment, faxed to counsel for U S West a notice of acceptance of the March 18 offer of judgment. Counsel for Perkins filed with *338 the District Court a notice оf acceptance of the offer of judgment on March 24, 1997, in compliance with Rule 68. Finally, on March 31, 1997, Perkins moved to amend the District Court’s March 20 judgment under Rule 59(e) to conform with the offer of judgmеnt. 4 The District Court granted Perkins’s motion to amend the court’s earlier judgment in favor of U S West on June 11,1997, entering judgment instead in favor of Perkins in the amount of $3,000, plus costs, interest, and attorney fees, as contеmplated by U S West’s Rule 68 offer of judgment.
U S West appeals, arguing that the District Court erred in holding that a Rule 68 offer of judgment remains valid for the statutorily prescribed ten-day period despite an intervening entry of summary judgment in favor of the party making the offer of judgment. U S West further argues that the District Court erred in amending its earlier grant of summary judgment in favor of U S West and entering judgment in favor of Perkins under Rule 59(e) and in аccordance with the Rule 68 offer of judgment.
I.
The District Court’s entry of amended judgment in favor of Perkins was based on its conclusion that Rule 68 mandates that any offer made under the Rule remains valid for ten days, regardless of an intervening entry of summary judgment. Because this conclusion is a legal interpretation of the Federal Rules of Civil Procedure, we review de novo.
See Jordan v. Time, Inc.,
The purpose of Rule 68 is to promote the compromise and settlement of litigation.
See Delta Air Lines, Inc. v. August,
Neither the parties, the District Court, or our own research has found a federal case directly addressing the issue before us. State courts, however, have addressed this *339 issue in the context of their comparable state rules regarding offers of judgment.
In
Centric-Jones Co. v. Hufnagel,
“The defendants ... certainly knew of the pending summary judgment motion when the offer of judgment was made. At that time, they could have chosen to make a private offer of settlement with a caveat as to the outcome of the summary judgment motion____ Here, [the defendants] assumed the calculated risk that a favorable decision of the pending summary judgment motion might negate the need for settlement, and they lost their gamble.”
Centric-Jones,
In
Hernandez v. United Supermarkets of Oklahoma, Inc.,
U S West draws our attention to a number of cases in support of its argument that the District Court erred in concluding that the offer of judgment remained valid for the full ten-day period. These cases, however, involve offers of judgment that were determined by the courts to be unenforceable under Rule 68 or its state equivalent as a result of the start or conclusion of trial, and therefore fail to support U S West’s position.
See Stoebe v. Merastar Ins. Co.,
We conclude that the plain language оf Rule 68 mandates that an offer of judgment remain valid and open for acceptance for the full ten-day period outlined in the Rule despite an intervening grant of summary judgment by the district court. Thе Rule contemplates invalidity of the offer only in instances where the offer is made less than ten days before the commencement of trial. Here, however, no trial date had been sеt and, despite a pending summary judgment motion and despite the. absence of any exigencies associated with an impending trial date, U S West made a strategic decision to make an оffer of judgment under Rule 68. Because the offer was not conditioned upon the District Court’s not granting U S West’s motion for summary judgment prior to Perkins’s acceptance of the offer, U S West assumed the risk thаt the District Court would rule favorably on U S West’s summary judgment motion during the ten-day period for acceptance of its Rule 68 offer. U S West took the chance that it could bring an end to this litigation for $3,000 (plus costs, interest, and attorney fees) pursuant to its Rule 68 offer and was unpleasantly surprised to find that, had it waited for the District Court’s ruling on the summary judgment motion, it could have brought an end to this *340 litigation for much less. Thе District Court did not err in concluding that the offer of judgment remained open for the full ten-day period despite the intervening grant of summary judgment.
II.
Having determined that the District Court did not err in its resolution of the Rulе 68 issue, we now turn to the District Court’s entry of amended judgment in favor of Perkins under Rule 59(e). We review a district court’s grant or denial of a Rule 59(e) motion to alter or amend a judgment for abuse of discretion.
See Twin City Const. v. Turtle Mountain Band of Chippewa Indians,
As noted above, the mandatory operation-of Rule 68 required the District Court to enter judgment as contemplated by U S West’s offer of judgment. Consequently, we hold that the District Court did not abuse its discretion by entering amended judgment in favor of Perkins pursuant to Rule 59(e).
III.
The judgment of the District Court is affirmed.
Notes
. The Honorable Lyle E. Strom, United States Distriсt Judge for the District of Nebraska. ■
. Federal Rule of Civil Procedure 68, titled “Offer of Judgment,” provides in pertinent part: At any time more than 10 days before the trial begins, a parly defending against a claim may serve upon the adverse party an offer to allow judgment to be taken against the defending party.... If within 10 days after the service of the offer the adverse party serves written notice that the offer is accepted, either party may then file the offer and notice of acceptance ... and thereupon the clerk shall enter judgment.
. Federal Rule of Civil Procedure 59(e), titled "Motion to Alter or Amend Judgment,” provides, "Any motion to alter or amend a judgment shall be filed no later than 10 days after entry of the judgment.”
. The district court will not, of course, enter judgment pursuant to a Rule 68 offer of judgment that contemplates illegal activity, regardless of the parties’ agreement.
