delivered the Opinion of the Court.
¶1 Appellant Kristine Hawkins filed a complaint against Respondents Dr. Randolph T. Harney, Dr. Minott E. Pruyn, and Pruyn Veterinary Hospital in the Fourth Judicial District Court, Missoula County. Hawkins’ complaint alleged that the Respondents breached their implied contracts as veterinarians by failing to provide competent veterinary services. Hawkins’ complaint further alleged that the Respondents had been negligent in treating her dog Laddie. Finally, the complaint alleged that the Respondents’ treatment of Laddie caused Hawkins to suffer emotional distress. The District Court determined that Hawkins failed to comply with Rule 26, M.R.Civ.P., and dismissed the case. Hawkins appeals. We affirm in part and reverse in part the judgment of the District Court.
¶2 We restate the issues on appeal as follows:
¶3 1. Did the District Court abuse its discretion when it found that *386 Hawkins failed to comply with Rule 26, M.R.Civ.P.?
¶4 2. Were the sanctions imposed by the District Court proper?
¶5 3. Did the District Court abuse its discretion when it denied Hawkins’ motion to compel discovery?
¶6 4. Did the District Court abuse its discretion when it denied Hawkins’ motion for leave to file a second amended complaint?
¶7 5. Did the District Court abuse its discretion when it failed to reverse its judgment for costs against Hawkins?
BACKGROUND
¶8 Kristine Hawkins owned a Shetland sheepdog named Laddie. On June 10, 1993, Laddie was struck by a motor vehicle. Hawkins promptly transported Laddie to Pruyn Veterinary Hospital in Missoula, Montana, for treatment. During his stay at Pruyn Veterinary Hospital, Laddie was treated by Dr. Randolph T. Harney and Dr. Minott E. Pruyn. However, after Dr. Pruyn discovered that Laddie had a broken vertebra, he recommended that Hawkins transport Laddie to Washington State University’s School of Veterinary Medicine in Pullman, Washington, for surgery. Hawkins followed Dr. Pruyn’s advice, and veterinarians at Washington State University performed surgery on Laddie’s spine on June 12, 1993.
¶9 The injuries to Laddie’s spine left him partially paralyzed for the remainder of his life. On June 10, 1996, Hawkins filed a complaint against Dr. Harney, Dr. Pruyn, and Pruyn Veterinary Hospital (the Respondents). Hawkins also filed her complaint against Washington State University and two of its veterinarians, however the District Court later dismissed these additional defendants from the case. Hawkins’ complaint alleged that the Respondents breached their implied contracts as veterinarians by failing to provide competent veterinary services. The complaint further alleged that the Respondents were negligent in treating Laddie. Finally, the complaint alleged that the Respondents’ treatment of Laddie caused Hawkins to suffer emotional distress.
¶10 On November 20, 1998, Hawkins filed an amended complaint, requesting exemplary and punitive damages. On May 16, 2001, Hawkins filed a motion to compel discovery, in which she asserted that the Respondents neglected to properly respond to her discovery requests. On July 3,2001, the Respondents filed a motion for summary judgment, alleging that Hawkins had failed to obtain an expert witness to support her claims. The District Court conducted a hearing on the Respondents’ summary judgment motion on September 18, *387 2001. On September 27, 2001, the District Court: (1) denied Hawkins’ motion to compel discovery because it found that the additional discovery materials requested by Hawkins were either irrelevant or confidential; and (2) denied the Respondents’ motion for summary judgment because it found the motion premature.
¶11 On December 7, 2001, Hawkins filed a motion for leave to file a second amended complaint. Hawkins’ second amended complaint sought to add an additional claim for fraud. The District Court denied Hawkins’ motion on January 15,2002, because it determined that the statute of limitations on her fraud claim had expired. On January 15, 2002, the Respondents filed a motion, requesting that the District Court: (1) compel Hawkins to answer their interrogatoiy regarding her expert witness; and (2) impose sanctions on Hawkins for failing to answer their interrogatory. On March 12, 2002, the District Court issued an order, concluding that Hawkins failed to comply with Rule 37(d), M.R.Civ.P., when she neglected to answer the Respondents’ interrogatory. The District Court then sanctioned Hawkins by barring the testimony of her expert witness and dismissing the case.
¶12 On May 20, 2002, Hawkins filed a motion to alter or amend the District Court’s order. On July 18, 2002, the District Court issued a second order, stating that it had incorrectly applied Rule 37(d), M.R.Civ.P., to the instant case. That is, the District Court found that because Hawkins had in fact answered the Respondents’ interrogatory, Rule 37(d), M.R.Civ.P, was inapplicable. However, the District Court also noted that Hawkins’ interrogatory answer was deficient. Therefore, the District Court concluded that dismissal of the case was merited, as Hawkins’ deficient answer failed to comply with Rule 26, M.R.Civ.P. Accordingly, the District Court denied Hawkins’ motion to alter or amend its March 12, 2002, order. Hawkins appealed the District Court’s orders on July 30, 2002.
¶13 On December 5,2002, the Respondents filed a motion to strike the reply brief which Hawkins submitted in support of her appeal before this Court. The Respondents’ motion asserted that Hawkins’ reply brief contained factual material that was not a part of the record in this case. As such, the Respondents requested that Hawkins’ reply brief be stricken from the record in its entirety. In response, Hawkins filed a cross-motion on December 16, 2002. Hawkins’ cross-motion requested that this Court strike several misstatements of fact which appeared in the Respondents’ brief.
¶14 It is well stated that “parties on appeal are bound by the record and may not add additional matters in briefs or appendices.”

STANDARD OF REVIEW
¶15 This Opinion addresses multiple issues, and as such, the appropriate standard of review for each issue will be set forth immediately preceding discussion of that issue.
DISCUSSION
ISSUE 1
¶16 Did the District Court abuse its discretion when it found that Hawkins failed to comply with Rule 26, M.R.Civ.P.?
¶17 Our standard of review concerning a district court’s ruling on a discovery matter is whether the district court abused its discretion.
McKamey v. State
(1994),
¶18 Hawkins contends that the District Court erred when it found that her supplemental answer to the Respondents’ interrogatory was deficient, and therefore, failed to comply with Rule 26(e), M.R.Civ.P., or Rule 26(b)(4)(A)(i), M.R.Civ.P. The interrogatory at issue in this case is interrogatory number fourteen, which the Respondents initially submitted to Hawkins on August 2, 1999. Interrogatory number fourteen provided, ,in pertinent part:
Please state the name, telephone number and present address of each person you expect to call as an expert on your behalf at trial in this action. With respect to each expert, please set forth the following information:
(a) The qualifications of each such expert witness, showing his age, formal education, a chronological history of the occupations or jobs he has held, publications he has authored, and if he has *389 previously been a witness, the date, name of the jurisdiction and name of the action in which he was last a witness;
(b) State in detail, the subject matter on which each such expert is expected to testify;
(c) State in detail, the substance of the facts and opinions to which each such expert is expected to testify;
(d) State in detail a summary of the grounds for each opinion by each expert[.]
¶19 Hawkins answered interrogatory number fourteen with the following phrase: “Not determined at this point.” The Respondents were not satisfied with Hawkins’ answer, and requested that she provide a supplemental answer to interrogatory number fourteen. Hawkins failed to provide a supplemental answer. The District Court then issued a joint scheduling order on November 5, 2001, which required that Hawkins furnish information regarding her expert witnesses to the Respondents no later than December 31, 2001.
¶20 On December 28, 2001, Hawkins provided the name and address of a veterinarian in Oklahoma that she intended to use as an expert witness. The Respondents, dissatisfied with the brevity of this information, filed a motion to compel discovery on January 15, 2002. The Respondents also requested that the District Court sanction Hawkins for her failure to comply with their discovery request. On January 23, 2002, Hawkins submitted a supplemental answer to interrogatory number fourteen, which consisted of approximately one page of text. The District Court determined that Hawkins’ supplemental answer was deficient, and failed to comply with Rule 26(e), M.R.Civ.P., or Rule 26(b)(4)(A)(i), M.R.Civ.P. The District Court then sanctioned Hawkins by barring the testimony of her expert witness and dismissing the case.
¶21 Rule 26(b)(4)(A)(i), M.R.Civ.P., addresses expert witnesses. Rule 26(b)(4)(A)(i), M.R.Civ.P, provides:
A party may through interrogatories require any other party to identify each person whom the other party expects to call as an expert witness at trial, to state the subject matter on which the expert is expected to testify, and to state the substance of the facts and opinions to which the expert is expected to testify and a summary of the grounds for each opinion.
The underlying policies of Rule 26, M.R.Civ.P., are to eliminate surprise and to promote effective cross-examination of expert witnesses.
Smith v. Butte-Silver Bow County
(1996),
*390
¶22 We examined Rule 26(b)(4)(A)(i), M.R.Civ.P., in
Scott v. E. I. Dupont De Nemours & Co.
(1989),
¶23 This Court examined a situation similar to the one in
Scott
in
Montana Power Co. v. Wax
(1990),
¶24 While the facts from Scott and Wax were similar, this Court reached opposite results when the answers to the interrogatories were examined in light of their compliance with the underlying policies of Rule 26, M.R.Civ.P. Accordingly, we take our cue from Scott and Wax, and analyze Hawkins’ answers to the Respondents’ interrogatories in light of the underlying policies of Rule 26, M.R.Civ.P.
¶25 In the instant case, Hawkins’ supplemental answer to the Respondents’ discovery request listed one expert, Dr. John Collins. Hawkins’ answer identified Dr. Collins by listing his address, age,
*391
schooling, and past employment. Hawkins’ supplemental answer further stated that the subject matter of Dr. Collins’ testimony would be the manner in which the veterinary medical case was handled. Hawkins’ supplemental answer also included approximately twenty lines of text that identified the substance of the facts and opinions to which Dr. Collins was expected to testify. Finally, Hawkins’ supplemental answer addressed the grounds for Dr. Collins’ opinions with the following phrase: “standard veterinary teaching and practice.” ¶26 As we noted above, the underlying policies of Rule 26, M.R.Civ.P., are to eliminate surprise and to promote effective cross-examination of expert witnesses.
Smith,
¶27 We further note that while we do not condone Hawkins’ tardiness in answering the Respondents’ interrogatories, such tardiness did not prejudice the Respondents. At the time the Respondents received Hawkins’ supplemental answer, this case had yet to be scheduled for trial. Consequently, the Respondents would have had adequate time to prepare their cross-examination of Dr. Collins.
See Scott,
ISSUE 2
¶28 Were the sanctions imposed by the District Court proper?
¶29 This Court generally defers to the decision of a trial court regarding sanctions for failure to comply with discovery procedures because the trial court is in the best position to assess whether parties
*392
are disregarding the rights of opposing parties in the course of litigation and to determine which sanctions for such conduct are most appropriate.
Patterson v. State Dept. of Justice,
¶30 As we noted above, the District Court sanctioned Hawkins for her failure to comply with Rule 26, M.R.Civ.P., by barring the testimony of her expert witness, and dismissing the case. However, in light of our above conclusion that Hawkins’ supplemental answer was adequate, we conclude that the District Court abused its discretion when it sanctioned Hawkins and dismissed her case.
ISSUE 3
¶31 Did the District Court abuse its discretion when it denied Hawkins’ motion to compel discovery?
¶32 As we noted above, we review a district court’s ruling on a discovery matter to determine whether the district court abused its discretion.
McKamey,
¶33 Hawkins filed a motion to compel discovery on May 16, 2001, in which she asserted that the Respondents failed to properly respond to several of her interrogatories, requests for production, and requests for admission. The District Court determined that the additional information requested by Hawkins was either irrelevant or confidential, and denied Hawkins’ motion on September 27, 2001.
¶34 On appeal, Hawkins alleges that the Respondents were required to answer her additional discovery requests. However, Hawkins fails to support her allegations with
relevant
authority. That is, while Hawkins devotes over seven pages to this issue in her opening brief, she fails to cite any authority that is factually relevant to the instant case. This portion of Hawkins’ opening brief is also devoid of citations to the record. Rule 23(a)(4), M.R.App.P., requires that an appellant provide an argument which contains “the contentions of the appellant with respect to the issues presented, and the reasons therefor, with citations to the authorities, statutes and pages of the record relied on.” We have repeatedly held that we “will not consider unsupported issues or arguments.”
In re Custody of Krause,
¶35 A district court’s decision is presumed to be correct.
Matter of M. J. W.,
ISSUE 4
¶36 Did the District Court abuse its discretion when it denied Hawkins’ motion for leave to file a second amended complaint?
¶37 We review a district court’s decision regarding a motion to amend a complaint for abuse of discretion.
Lindey’s v. Professional Consultants
(1990),
¶38 Hawkins contends that the District Court abused its discretion when it denied her motion for leave to file a second amended complaint. The second amended complaint which Hawkins sought to file contained an additional claim for fraud.
¶39 Rule 15(a), M.R.Civ.P., addresses amendments to pleadings. Rule 15(a), M.R.Civ.P., provides, in pertinent part, that:
“A
party may amend the party’s pleading once as a matter of course ... Otherwise a party may amend the party’s pleading only by leave of court or by written consent of the adverse party; and leave shall be freely given when justice so requires.” However, while Rule 15(a), M.R.Civ.P., dictates that leave to amend shall be freely granted, this Court has previously held that leave to amend is properly denied when the amendment is futile or legally insufficient to support the requested relief.
Hobble-Diamond Cattle v. Triangle Irr.
(1991),
¶40 In the instant case, the District Court considered the merits of Hawkins’ second amended complaint and found that the statute of limitations on Hawkins’ fraud claim had expired. Therefore, the District Court concluded that Hawkins’ second amended complaint was futile. As a preliminary matter, we note that although Hawkins sought to file her second amended complaint on December 7, 2001, it is the date that Hawkins filed her original complaint which is germane to our analysis of this issue. That is, Rule 15(c), M.R.Civ.P., provides that: *394 “Whenever the claim or defense asserted in the amended pleading arose out of the conduct, transaction, or occurrence set forth or attempted to be set forth in the original pleading, the amendment relates back to the date of the original pleading.” Accordingly, we will analyze Hawkins’ fraud claim with regard to the date she filed her original complaint.
¶41 Section 27-2-203, MCA (1991), addresses actions for relief on grounds of fraud. Section 27-2-203, MCA (1991), provides that:
The period prescribed for the commencement of an action for relief on the ground of fraud or mistake is within 2 years, the cause of action in such case not to be deemed to have accrued until the discovery by the aggrieved party of the facts constituting the fraud or mistake.
¶42 Additionally, § 27-2-102, MCA (1991), provides, in pertinent part, that:
(3) The period of limitation does not begin on any claim or cause of action for an injury to person or property until the facts constituting the claim have been discovered or, in the exercise of due diligence, should have been discovered by the injured party if:
(a) the facts constituting the claim are by their nature concealed or self-concealing; or
(b) before, during, or after the act causing the injury, the defendant has taken action which prevents the injured party from discovering the injury or its cause.
¶43 This Court has interpreted the above two statutes to conclude that: “The statute of limitations for an action based on fraud begins when the fraud occurs unless the facts which form the basis for the allegation are, by their nature, concealed.”
Cartwright v. Equitable Life Assur.
(1996),
*395 ISSUE 5
¶44 Did the District Court abuse its discretion when it failed to reverse its judgment for costs against Hawkins?
¶45 We review a district court’s award of costs to determine whether the district court abused its discretion.
Mularoni v. Bing,
¶46 The District Court determined that the Respondents were entitled to recover $822 in costs from Hawkins. However, the Respondents later conceded that because they failed to file a timely Bill of Costs, they were not entitled to recover their costs from Hawkins. In light of the Respondents’ concession, Hawkins asserts that the District Court abused its discretion when it failed to reverse its judgment for costs. We agree. Accordingly, we reverse the District Court’s judgment for costs.
¶47 For the foregoing reasons, the judgment of the District Court is affirmed in part, reversed in part, and remanded for proceedings consistent with this Opinion.
