JUSTICE MORRIS
delivered the Opinion of the Court.
¶1 Appellant Allianz Global Risks US Insurance Company (Allianz) appeals the decision of the Nineteenth Judicial District Court, Lincoln County. The District Court entered summary judgment in favor of Appellee Lincoln County Port Authority (Port) on the issue of whether the Port qualified as an insured under the Allianz insurance policy. The District Court also granted the Port’s motion to dismiss Allianz’s counterclaim that had sought to reform the insurance policy. We affirm in part, reverse in part, and remand.
¶2 We address the following issues on appeal:
1. Whether the Port is an “insured” as contemplated by the Allianz policy.
2. Whether sufficient collateral evidence entitles Allianz to reformation of the policy.
[62]*62
3. Whether the District Court correctly valued the Plywood Plant Building.
4. Whether prejudgment interest began to accrue on the date of the fire at the Plywood Plant Building.
PROCEDURAL AND FACTUAL BACKGROUND
¶3 The Montana Association of Counties (MACo) is a nonprofit corporation that acts on behalf of Montana’s 56 counties. MACo represents the interests of county governments before the Montana legislature, administrative agencies, and the federal government.
¶4 MACo created a property and liability self-insured risk pool, the Montana Association of Counties Joint Powers Insurance Authority (MACo/JPIA), in the 1980s. Through MACo/JPIA, MACo self-insures its member counties and related entities. MACo/JPIA obtained catastrophic property insurance to supplement its pooled fund of public monies used for self-insurance. The catastrophic insurance serves as excess insurance designed to mitigate MACo’s loss on large claims that exceed a designated amount. MACo/JPIA purchased the catastrophic insurance from Allianz to cover damages over $100,000.
¶5 Lincoln County is a MACo member. Lincoln County created the Port as a separate public body pursuant to § 7-14-1104, MCA. The Port seeks to foster economic development in Lincoln County through its operation of an industrial facility in Libby, Montana. The industrial facility consists of several buildings associated with a former lumber mill. The lumber mill includes a Plywood Plant Building. The Port insured the Plywood Plant Building, along with its other buildings at the lumber mill, through the MACo/JPIA self-insured risk pool.
¶6 Part of the roof of the Port’s Plywood Plant Building collapsed from heavy snow during the winter of 2007-2008. The Port submitted an insurance claim for damages caused by the collapse of the roof. Allianz assessed the damage to the Plywood Plant Building at 29% of its value. Allianz paid the Port over $3 million for the loss of this portion of the Plywood Plant Building consistent with its coverage obligations under the catastrophic insurance policy with MACo/JPIA.
¶7 MACo/JPIA thereafter informed the Port in a June 24,2008, letter that it no longer would insure the Plywood Plant Building. The 2009-2010 schedule ofinsured locations omitted the Plywood Plant Building. This omission coincided with the Port’s decision to demolish the part of the Plywood Plant Building that had collapsed due to the heavy snowfall. The Port intended to renovate the part of the Plywood Plant [63]*63Building that remained standing after the roof collapsed.
¶8 The Port was in the process of demolishing the damaged part of the Plywood Plant Building when a fire destroyed the building entirely on February 25, 2010. The Port submitted an insurance claim for damages caused by the fire to the Plywood Plant Building. MACo/JPIA and Allianz refused to cover this loss. The Port filed this suit against Allianz.
¶9 The District Court granted summary judgment in favor of the Port. The District Court determined that the Allianz policy insures the Port and ordered the parties to conduct appraisal proceedings. The District Court also granted the Port’s motion to dismiss Allianz’s counterclaim that had sought to reform Allianz’s policy to exclude coverage of the Plywood Plant Building.
¶ 10 During the following appraisal, the parties disagreed whether the valuation provision in Allianz’s policy limited the Port’s recovery for that portion of the Plywood Plant Building that had been slated for demolition to the increased cost of demolition. The District Court issued an order on May 22, 2012, that clarified that the valuation provision did not apply in appraisal proceedings.
¶11 The District Court entered its final judgment on July 31, 2012. The District Court awarded a principal amount of $6,060,980 based on the findings of the appraisal panel and the parties’ stipulation to the value of certain other damages, $1,474,560 in prejudgment interest beginning on the date of the fire, and $2,511,847 in attorneys’ fees and costs. The total award with fees and interest now exceeds $10 million.

DISCUSSION
¶13 Whether the Port is an “insured” as contemplated by the Allianz policy.
¶14 The Port argues that it qualifies as an insured under the Allianz [64]*64policy’s definition. The Port claims that the policy’s definition of “insured” includes the MACo counties and any other entities that receive insurance through MACo/JPIA. Allianz argues that it intended this language to cover only MACo and MACo/JPIA.
¶ 15 We begin our analysis by examining the insurance contract’s plain language. We will not rewrite clear and explicit language in an insurance contract. Monroe v. Cogswell Agency, 2010 MT 134, ¶ 15, 356 Mont. 417, 234 P.3d 79. We interpret an insurance contract’s terms “according to their usual, common sense meaning,” that is, how they would be understood by “a reasonable consumer of insurance products.” Steadele v. Colony Ins. Co., 2011 MT 208, ¶ 18, 361 Mont. 459, 260 P.3d 145.
¶16 The Allianz policy defines the “insured” as MACo “and its subsidiary, associated or allied company, corporation, firm, organization.” All of the terms used by Allianz describe one single entity, not multiple entities. The language of the contract would lead us to believe that the policy’s definition of “insured” covers only MACo and one other entity, presumably MACo/JPIA. Steadele, ¶ 18.
¶17 This understanding of “insured,” however, cannot be reconciled with other provisions in the Allianz policy. We construe an insurance policy in accordance with the entirety of its terms and conditions. Lambert Well Serv. u. Wellington Specialty Ins. Co., 2008 MT 212, ¶ 11, 344 Mont. 204, 186 P.3d 1255. In other words, we read the Allianz policy as a whole and attempt to reconcile its various parts to give the entire policy meaning and effect. Lambert, ¶ 11.
¶18 The Allianz policy defines “insured property” to include real property and personal property. The personal property covered by the policy includes personal property of the following type: (1) “owned by the Insured,” (2) “of officers and employees of the Insured,” and (3) “of others in the Insured’s custody.” The substitution of “MACo and MACo/JPIA” for the term “insured” in each of these provisions would undermine the policy’s definition of “insured property.” MACo counties and other associated entities owned the personal property insured by the policy. MACo or MACo/JPIA did not own the personal property in question. MACo’s or MACo/JPIA’s employees did not own the personal property in question. And none of the personal property contemplated by the policy resided in the custody of MACo or MACo/JPIA.
¶ 19 We note further that portion of the policy that sets forth the action to be taken in the event of a loss. The policy obligates the insured to protect the subject property from further loss or damage. The insured [65]*65also must provide an inventory of lost, destroyed, or damaged items. MACo lacks the ability to undertake the protection of the insured’s properties or to prepare inventories of lost, destroyed, or damaged items. The owner of the property in question undertakes these duties.
¶20 The use of “insured” under the policy’s discussion of “insured property” and “requirements in case of loss” conflict with Allianz’s claim that only MACo and MACo/JPIA qualify as insureds under the policy. These provisions of the policy raise ambiguities. We must reconcile these seemingly contradictory provisions to give meaning and effect to the entire policy. Lambert, ¶ 11. The disconnect between the policy’s definition of “insured” and its definition of “insured property” and “requirements in case of loss” creates ambiguity regarding the policy’s definition of “insured.” This ambiguity requires us to look beyond the plain language of the Allianz policy’s definition of “insured.”
¶21 We consider extrinsic evidence to interpret this ambiguous provision and determine who qualifies as an intended “insured” under the policy. Estate of Irvine v. Oaas, 2013 MT 271, ¶ 22, 372 Mont. 49, 309 P.3d 986 (allowing a court to consider extrinsic evidence when it interprets a contract that contains ambiguous terms). The extrinsic evidence demonstrates that MACo exists for the express purpose of serving as a single entity to represent Montana’s counties, including Lincoln County, before the Montana legislature, administrative agencies, and the federal government. MACo has no existence separate from the collection of Montana counties that comprise its membership.
¶22 Lincoln County created the Port pursuant to § 7-14-1104, MCA. Section 7-14-1104 provides thatthe Port’s purpose involves “public and governmental functions.” These governmental functions include promoting economic development. Section 7-14-1104(1), MCA. Subsection 2 further authorizes the Port to use any property that it owns as security to issue bonds “for an essential public and governmental purpose.” Section 7-14-1104(2), -1133(4), MCA. This statute indicates that the Port, as a subunit of Lincoln County, exists in “association] or alli[ance]” with Lincoln County.
¶23 The fact that the Port qualified for insurance through the MACo/JPIA insurance pool in the first place further suggests an “association] or alli[ance]” between the Port and MACo. The Port submitted its insurance applications, information, and premium payments to MACo/JPIA, similar to any other MACo/JPIA-member county. MACo/JPIA processed the Port’s application and readily [66]*66accepted its premium payment. MACo/JPIA, one of MACo’s insurance pools, serves as an extension of MACo. The Port’s interactions with MACo/JPIA support the Port’s claim of its “association] or alli[ance]” with MACo pursuant to the terms of the Allianz policy.
¶24 Additionally, MACo/JPIA admitted to having adopted the language for its own property insurance policy form directly from the Allianz insurance policy form. MACo/JPIA and Allianz used insurance policy forms with identical language. MACo/JPIA conceded that it insured the Port’s property. The Port’s satisfaction of the definition of “insured” under MACo/JPIA’s policy suggests that the Port also would satisfy the definition of “insured” under the same language as used in the Allianz policy.
¶25 “Associated” as used in insurance policies often connotes entities closely joined with others in a common purpose. Old Colony Ins. Co. v. Jeffery’s Mill & Warehouse, Inc., 146 F. Supp. 277, 279 (N.D. Cal. 1956). “Associated” further implies “participation by each of the individuals ... in the achievement of a common purpose.” Old Colony Ins. Co., 146 F. Supp. at 279. The Port performs public and governmental functions that include economic development in Lincoln County. Section 7-14-11Ó4, MCA. Lincoln County, a political subdivision of Montana, created the Port to allow it to pursue these public and governmental functions related to economic development in Lincoln County. The Port and Lincoln County share the common purpose of performing public and governmental functions directly for the benefit of the residents of Lincoln County. The Port and Lincoln County each participate in the achievement of this common purpose.
¶26 The Port operates under the auspices of Lincoln County. Section 7-14-1104, MCA. Lincoln County, along with other counties in Montana, in turn, created MACo to represent the interests of its member counties. MACo, too, operates under the auspices of Lincoln County and its other member counties as MACo performs its functions directly for the benefit of Lincoln County and its other member counties. These relationships comport with the common purpose and participation contemplated by the Court in Old Colony Ins. Co., 146 F. Supp. at 279.
¶27 The Court in Travelers Indem. Co. v. United States, 543 F.2d 71, 76 (9th Cir. 1976), explained that “affiliated” and “associated” as used in an insurance policy should be interpreted “to make them applicable to persons, things, or entities of the same general nature or class” as those entities owned or controlled by the insured. The court relied on [67]*67this analysis to reject a claim by the United States, acting through the Bonneville Power Administration (BPA), that a subrogation waiver clause in an insurance contract shielded it from subrogation efforts by an insurer for a private electric power company. Travelers, 543 F.2d at 73. The insurer sought subrogation from BPA following an explosion at a power generation facility operated by BPA that had destroyed the private company’s property. Travelers, 543 F.2d at 73-74. The Court determined that, as a governmental entity, BPA had “objectives and responsibilities apart from those of private power companies.” Travelers, 543 F.2d at 76.
¶28 The Port and Lincoln County perform public and governmental functions. Section 7-14-1104, MCA. MACo promotes the effective operation of its members-local political subdivisions. Entities of the same general nature possess similar responsibilities as contemplated by subrogation waiver clauses. Travelers, 543 F.2d at 76. Extrinsic evidence leads us to conclude that the Port and Lincoln County would fit within the scope of entities of the same general nature as MACo as all three exist to promote county governmental functions.
¶29 Further analysis of the policy also leads us to conclude that the Allianz policy does not constitute reinsurance. A policy of reinsurance with the Port, as an “original insured,” generally would bar the Port from bringing a direct claim against Allianz as a mere “reinsurer.” See Steven Plitt, Daniel Maldonado & Joshua D. Rogers, Couch on Insurance vol. 1A, § 9:30 (3d ed., West 2010) [hereinafter Couch on Insurancy]. The evidence instead suggests that Allianz simply provided an excess carrier high-deductible plan for the MACo/JPIA self-insurance pool.
¶30 MACo/JPIA’s authorizing statute provides that political subdivisions that elect to procure insurance pursuant to the section “may obtain excess coverage from a surplus lines insurer.” Section 2-9-211(1), MCA (emphasis added). The statute indicates that the political subdivisions themselves would be the insured under any excess coverage policy. The joint powers agreement that established MACo/JPIA further supports this proposition. The agreement provides that member counties decided to create a joint risk-sharing pool to self-insure and “to purchase catastrophe, excess and/or aggregate stop loss insurance when deemed prudent.” Section 2-9-211(1), MCA, authorizes this type of insurance arrangement.
¶31 The operation of the joint-insurance pool also supports the notion [68]*68that Allianz provided excess insurance. MACo/JPIA listed Allianz as an insurer on the declarations page of the Port’s policy. The Port negotiated directly with Allianz in handling an earlier claim. All of these items of extrinsic evidence offer further indicia that Allianz served as an excess insurance carrier, rather than as a reinsurer. Allianz’s status as an excess insurance carrier normally would allow the Port to bring a claim directly against Allianz as an insured. See Tex. Dept. of Ins. v. Am. Nat’l Ins. Co., 55 Tex. Sup. J. 705 (Tex. 2012) (providing that excess insurance represents “an agreement to indemnify against any loss that exceeds the [insured’s] amount of primary or other coverage”).
¶32 The Port would not necessarily be precluded from bringing a claim against Allianz even if Allianz had served as a reinsurer. The record indicates that the Port dealt directly with Allianz when the Plywood Plant Building’s roof collapsed. Consistent direct contact between an original insured (the Port) and a reinsurer (Allianz) may waive a reinsurer’s right to immunity from being sued by an original insured. Allstate Ins. Co. v. Administratia Asigurarilor De Stat, 948 F. Supp. 285, 307-08 (S.D.N.Y. 1996); Couch on Insurance at § 9:30.
¶33 We must construe ambiguous language in a contract against the contract’s drafter. Mary J. Baker Revocable Trust v. Cenex Harvest States, Coops., Inc., 2007 MT 159, ¶ 34, 338 Mont. 41, 164 P.3d 851. Allianz drafted the policy. We construe against Allianz the Allianz policy’s use of “associated or allied” when combined with the policy’s discussion of “insured property” and “requirements in case of loss.” Mary J. Baker, ¶ 34. We agree with the District Court’s determination that the Port qualifies as an insured under the terms of the Allianz policy.
¶34 Whether sufficient collateral evidence entitles Allianz to reformation of the policy.
¶35 Allianz argues that Allianz and the Port both understood that the Allianz policy would not cover the Plywood Plant Building. Allianz relies primarily upon the notice from MACo/JPIA to the Port that the Plywood Plant Building no longer would be insured. Allianz seeks to reform the contract to conform to what it describes as the parties’ original intent. Allianz seeks to add language to the Allianz policy that specifically would exclude the Plywood Plant Building from any coverage.
¶36 The District Court determined that § 33-15-302, MCA, prohibits reformation of insurance policies. The Port suggests that we need not [69]*69determine whether § 33-15-302, MCA, bars reformation of an insurance contract as reformation cannot be used to correct an unforeseen legal effect of an insurer’s policy. The Port underscores that the Allianz policy provides insurance for any “location” listed on the latest schedule. The policy also provides that “[i]nsured [l]ocation(s) includes the area within one thousand (1,000) feet of such ‘location.’ ” The Plywood Plant Building sat within 1,000 feet of an insured building included on the schedule of insured locations.
¶37 We will revise a contract when, through fraud, mutual mistake of the parties, or a mistake of one party which the other at the time knew or suspected, a written contract does not truly express the intention of the parties. Thibodeau v. Bechtold, 2008 MT 412, ¶ 22, 347 Mont. 277, 198 P.3d 785 (citing § 28-2-1611, MCA). To obtain judicial reformation, the parties must have reached a mutual understanding and executed a written contract in furtherance of that understanding, but made a mistake incorporating the understanding that they had reached into the contract that they executed. Thibodeau, ¶ 22.
¶38 The record makes Allianz’s and the Port’s intent clear: to exclude the Plywood Plant Building, and only the Plywood Plant Building, from coverage under the 2009-2010 Allianz policy. Allianz had paid coverage for the Plywood Plant Building following the collapse of the roof in 2008. Allianz canceled coverage for the Plywood Plant Building after the roofs collapse.
¶39 The Trust Administrator for MACo/JPIA attested that “MACo/JPIA [had] sent a letter to Tom Wood, the local insurance agent, cancelling property coverage and premise liability coverage for the Plywood Plant Building.” (Emphasis added). MACo/JPIA subsequently informed the Port in writing on June 24, 2008, that the “[p]roperty and [liability coverage for the Plywood [P]lant [B'iuilding for the Lincoln Port Authority ... is cancelled effective July 1, 2008.” (Emphasis added). This letter mentions only the Plywood Plant Building.
¶40 Thomas Wood (Wood), the owner of the insurance agency that had helped the Port obtain insurance coverage, forwarded another copy of MACo/JPIA’s letter to the Port with his own cover letter on June 26, 2008. Wood attested in his affidavit that his letter had “advis[ed the Port] that there were no other insurance markets that would insure the Plywood Plant Building.” (Emphasis added). Wood further attested that the Port prepared a “revised S.O.V. [Statement of Values] removing the Plywood Plant Building” that was “[b]ased on [70]*70MACo/JPIA’s advisement that it would no longer insure the Plywood Plant Building.” (Emphasis added).
¶41 The Port understood that no coverage existed for the Plywood Plant Building, and acted accordingly. The Port submitted a Statement of Values following the notice of canceled coverage under the 2009-2010 Allianz Policy. The Port’s Statement of Values included each building that had been in the prior Statement of Values with the specific omission of the Plywood Plant Building. This sole omission clarified the Port’s understanding of the canceled coverage under the 2009-2010 Allianz Policy.
¶42 Publicity surrounding the fire that destroyed the Plywood Plant Building is further informative. The Missoulian reported the Port’s belief on February 26, 2010, that “the building itself was not insured ... ‘ever since the snow collapsed parts of the roof, the insurance company dropped us.’ ” (Emphasis added). Libby’s The Western News reported the industrial site manager’s statement on March 8, 2010, that “the industrial site’s insurance on the building had been dropped when the company paid a $3.2 million settlement after the roof collapsed two years ago.” (Emphasis added). The record makes clear that the parties mutually understood that coverage for the Plywood Plant Building, and only the Plywood Plant Building, no longer existed. Thibodeau, ¶ 22.
¶43 The parties created a revised contract based upon their shared understanding. The 2009-2010 Allianz policy incorporated the Port’s revised Statement of Values, which specifically had excluded the Plywood Plant Building from the schedule of covered properties. The revised schedule of covered properties in the 2009-2010 Allianz policy represents the parties’ incorporation of their mutual understanding into the writing. Thibodeau, ¶ 22. Allianz now claims, however, that both parties also intended the Allianz policy to exclude coverage of the area within the 1,000 foot radius of other buildings. We disagree.
¶44 The record contains no indication that either Allianz or the Port intended to exclude coverage of the area within the 1,000 foot radius of other covered buildings, regardless of what that area contained. The parties agreed that the Plywood Plant Building itself would no longer be covered. They did not agree that any salvage materials located within 1,000 feet of other covered buildings would not be covered. The parties reached a mutual understanding that Allianz no longer would cover the Plywood Plant Building, and only the Plywood Plant Building. The parties committed that understanding to writing in the [71]*712009-2010 Allianz policy.
¶45 The evidence in the record upon which Allianz relies to argue for reformation to exclude the 1,000 foot radius fails to indicate any intent to exclude that radius. Allianz relies heavily upon the facts that the Port did not include the Plywood Plant Building in the Statement of Values and that the Port did not pay any premium to Allianz for the Plywood Plant Building. The Port undertook both of these actions, however, in furtherance of its understanding that Allianz would not provide coverage for the Plywood Plant Building in the 2009-2010 Allianz policy.
¶46 Allianz does not identify any other evidence in the record that would indicate the parties’ mutual intent to exclude the 1,000 foot radius. Allianz has failed to establish that the 2009-2010 insurance policy expressed anything other than what the parties mutually had intended. We decline to reform the 2009-2010 Allianz policy.
¶47 We need not reach Allianz’s arguments that Montana law allows reformation of an insurance policy. Reformation as a contract remedy remains available only in those situations where a discrepancy exists between the understanding that parties reached and the contract that they executed. Thibodeau, ¶ 22. The absence of a discrepancy eliminates reformation as a remedy. Thibodeau, ¶ 22.
¶48 In the absence of a discrepancy, “the language of a contract governs its interpretation if that language is clear and explicit.” Heggem v. Capitol Indem. Corp., 2007 MT 74, ¶ 22, 336 Mont. 429, 154 P.3d 1189 (citing § 28-3-401, MCA). The Port and Allianz each agreed to a contract that specified that “[i]nsured [l]ocation(s) include[] the area within one thousand (1,000) feet of such “location,”’ referring to any location listed in the 2009-2010 schedule of coverage. The Port paid a premium to Allianz in order to receive this 1,000-foot coverage under Allianz’s policy. Neither party disputes that the remnants of the Plywood Plant Building fall squarely within the 1,000-foot radius covered by Allianz’s policy. The language in the 2009-2010 Allianz policy clearly and explicitly indicates that Allianz will provide coverage to the area within 1,000 feet of any covered location. Allianz must provide that coverage. The language of the Allianz policy provides the Port with coverage for the remnants of the Plywood Plant Building. ¶49 The Dissent posits that the parties never intended for the general provision that insures property within 1,000 feet of an insured location to cover locations deleted from coverage. (J. Rice Dissenting, ¶ 73.) Allianz would not need to seek reformation if the policy clearly stated [72]*72as. much. The fact that Allianz seeks reformation of the policy represents a tacit acknowledgment that the policy as written covers the Plant remnants. The Dissent further maintains that under this Court’s interpretation, coverage for a particular property never could be deleted unless the parties rewrote the policy. Any required rewrite would be simple and easily applied along the following lines: “Insured Location(s) includes the area within one thousand (1,000) feet of such ‘location,’ unless the location for which recovery is sought specifically has been deleted from coverage. ”
¶50 Perhaps Allianz neglected to change its policy to reflect its apparent belief that the Plywood Plant Building would not be covered under any circumstances. Equity does not require us “to reform a contract to correct an error ... when due diligence would have uncovered and corrected the error.” Martin v. Crown Life Ins. Co., 202 Mont. 461, 469, 658 P.2d 1099, 1104 (1983). The defendant in Martin, an insurance company, waited more than a year to correct an error that it had made in its insurance policy and certificate of insurance. Martin, 202 Mont. at 469, 658 P.2d at 1103. We refused to reform the contract to correct the insurance company’s mistake in the absence of its own due diligence. Martin, 202 Mont. at 469, 658 P.2d at 1104. ¶51 Allianz, too, waited more than a year to modify its policy to eliminate any ambiguity whether it covered the Plywood Plant Building as being located within 1,000 feet of an insured building. Allianz’s exercise of due diligence should have discovered any error in the content of its insurance policy. Allianz has failed to establish that its insurance policy expressed something other than what the parties mutually had intended.
¶52 Whether the District Court correctly valued the Plywood Plant Building.
¶53 The District Court ordered Allianz and the Port each to select an appraiser to determine how much Allianz owes the Port under the policy. Allianz argues that the adjustment procedure in the valuation section of its policy should have guided the appraisers in determining the amount of loss that the Port should receive. The adjustment procedure in section 10(f) addresses property scheduled for demolition. Allianz maintains that section 10(f) limits the Port’s recovery to the “increased cost of demolition” for the portion of the Plywood Plant Building that the Port had slated for demolition.
¶54 The section of Allianz’s policy that addresses appraisal does not require appraisers to follow Allianz’s valuation scheme. Indeed, the [73]*73section provides no limitations on the valuation of property scheduled for demolition. The valuation provision for property scheduled for demolition applies only when the parties agree on the amount of loss. The valuation provision has no relevance when the parties agree to submit their valuation to an appraiser.
¶55 The fact that the appraisers do not have to follow the Allianz policy’s adjustment procedures does not relieve their valuation of the Plywood Plant Building of all restrictions. Allianz’s policy stipulates that appraisers will determine the amount of loss based upon “actual cash value” and “replacement cost.” Allianz’s policy defines “actual cash value” as the cost of replacement minus depreciation. Allianz’s policy dictates that the insured shall receive “actual cash value” if an insured fails to repair or replace its damaged property within two years. An insured receives “replacement cost” only if the insured repairs or replaces within two years.
¶56 The parties disagree whether the Port should receive “replacement costs” for those portions of the Plywood Plant Building that the Port had slated for demolition. This disagreement revolves around the $1,925,000 that the appraisers have determined represents the “replacement cost” for those portions of the Plywood Plant Building that had been slated for demolition.
¶57 The District Court allowed the Port to choose “replacement cost” even for those portions of the Plywood Plant Building that the Port had slated for demolition. The District Court waived the requirement in the policy that the Port had to repair or replace the damaged building within two years. This two-year repair window had lapsed since the 2010 fire. The District Court relied on the fact that Allianz’s wrongful denial of coverage had stymied any efforts by the Port to rebuild.
¶58 The District Court cited numerous cases to support its determination. The cases focus on the fact that insurers’ refusals to pay recovery to their insureds prevented the insureds from repairing or replacing as the insureds lacked sufficient money for such efforts. See Zaitchick v. American Motorists Ins. Co., 554 F. Supp. 209, 217 (S.D.N.Y. 1982), aff'd, 742 F.2d 1441 (2d Cir. 1983); Columbia Mut. Ins. Co. v. Sanford, 920 S.W.2d 28, 30 (Ark. App. 1996); Pollock v. Fire Ins. Exch., 423 N.W.2d 234, 236-37 (Mich. App. 1988). In two of the cited cases—Conrad Bros. v. John Deere Ins. Co., 640 N.W.2d 231, 242 (Iowa 2001) and Bailey v. Farmers Union Coop. Ins. Co., 498 N.W.2d 591, 598-99 (Neb. App. 1992)-courts determined that the insured parties would have rebuilt, but for repudiation of their policies by their [74]*74insurers.
¶59 The Port never intended to rebuild the damaged portions of the Plywood Plant Building before the 2010 fire. The Port received over $3 million for the damage to the Plywood Plant Building after the roof collapsed during the winter of2007-2008. The Port in fact affirmatively intended to demolish those portions of the Plywood Plant Building that had been damaged from the roof collapse before the 2010 fire.
¶60 The Port apparently did not replace or repair any portions of the Plywood Plant Building that had been slated for demolition within two years of the fire. The Port would receive far more for the Plywood Plant Building than it had contemplated under the policy if we allow the Port to elect to receive “replacement cost” for those portions of the Plywood Plant Building that it had not intended to repair or replace.
¶61 Property insurance serves to place the insured in the same position in which he would have been had there been no loss. See Lee v. Providence Wash. Ins. Co., 82 Mont. 264, 276, 266 P. 640, 644 (1928). The Port would land in a better place than it would have without the fire if we allow the Port to receive “replacement cost” for those portions of the Plywood Plant Building that it had slated for demolition. The Port should receive only “actual cash value” for those portions of the Plywood Plant Building that it had slated for demolition. Most likely “actual cash value” for those portions of the Plywood Plant Building that the Port had slated for demolition will amount only to salvage value as these portions of the building have depreciated greatly. We reverse the District Court’s determination that the Port should receive “replacement cost” for the portions of the Plywood Plant Building that had been slated for demolition.
¶62 Whether prejudgment, interest began to accrue on the date of the fire at the Plywood Plant Building.
¶63 The Port seeks to recover interest, pursuant to § 27-1-211, MCA, from the date of the fire that destroyed the Plywood Plant Building. Section 27-1-211, MCA, allows an insured party to recover interest under certain circumstances. A party must fulfill three prerequisites: (1) “an underlying monetary obligation must exist,” (2) “the amount of recovery must be capable of being made certain,” and (3) “the right to recover must vest on a particular day.” Mont. Petroleum Tank Release Comp. Bd. v. Crumleys, Inc., 2008 MT 2, ¶ 99, 341 Mont. 33, 174 P.3d 948.
¶64 Conversely, an award of prejudgment interest would not be available “when the amount of a party’s damages is uncertain or [75]*75disputed.” Crumleys, ¶ 99. The insurer in Crumleys had breached its duty to indemnify its insured’s loss that had resulted from a leak in an underground diesel tank. Crumleys, ¶ 1. The parties could not ascertain the amount of damages that had occurred as a result of the breach until the date that the jury returned a verdict and awarded damages. Crumleys, ¶ 100. Under those circumstances, “no interest can run until a fixed amount of damages has been arrived at, either by agreement, appraisal, or judgment.” Crumleys, ¶ 100 (quoting Northern Mont. Hosp. v. Knight, 248 Mont. 310, 321, 811 P.2d 1276, 1282 (1991)).
¶65 Allianz disputed whether it insured the Plywood Plant Building from the time that the Port submitted its claim. The amount of damages remains uncertain. The complexity of this case prevents the Port from invoking § 27-1-211, MCA, in order to argue that prejudgment interest should have begun to accrue on the date of the fire.
¶66 The Port argues alternatively that § 27-1-312, MCA, not § 27-1-211, MCA, controls the outcome. Section 27-1-312, MCA, provides that the “detriment caused by the breach of an obligation to pay money only is deemed to be the amount due by the terms of the obligation with interest thereon.” The “amount due by the terms of the obligation” in this case remains, however, far from clear.
¶67 We agree that Allianz must pay interest. The language of both § 27-1-211, MCA, and § 27-1-312, MCA, indicates that Allianz must pay interest on the amount that it owes the Port. Section 27-1-312, MCA, remains silent as to the date on which interest should begin to accrue. Section 27-1-312, MCA, refers to “the amount due by the terms of the obligation.” Section 27-1-312, MCA, provides no guidance regarding timing. On the other hand, § 27-1-211, MCA, entitles a party to recover damages once they are “certain or capable of being made certain by calculation.” We must rely on § 27-1-211, MCA, to determine when interest began to accrue on the amount of damages that Allianz must pay to the Port.
¶68 The date of the fire cannot mark the date that interest began to accrue. See Crumleys, ¶ 99. The amount of damages remained incapable of being made certain by calculation at the time of the fire. A numerical amount for damages actually must be calculated, or be capable of calculation, before interest can begin to accrue. Section 27-1-211, MCA; see also, Northern Mont. Hosp., 248 Mont. at 320-21, 811 P.2d at 1282. For example, in Northern Montana Hospital we [76]*76determined that the right to recover interest vested only on the date that the jury returned a verdict for the monetary amount of $1,750,000. Northern Mont. Hosp., 248 Mont. at 321, 811 P.2d at 1282. Here, the parties could not agree on how the appraisers should calculate the damages. No amount could be assigned for the damages to the portion of the Plywood Plant Building that the Port had slated for demolition.
¶69 The District Court on remand will determine the amount of damages that Allianz owes the Port for those portions of the Plywood Plant Building that had been slated for demolition. The damages at that point will be “capable of being made certain by calculation.” Section 27-1-211,'MCA. The Port will receive “actual cash value” for the portions of the Plywood Plant Building that it had slated for demolition. The appraisers can calculate this value. The District Court’s adoption of the appraiser’s new valuation on remand will mark the point at which interest shall begin to accrue. The Port’s loss entitles it to post-judgment interest, but not prejudgment interest for those portions of the Plywood Plant Building that had been slated for demolition. Section 27-1-211, MCA.
CONCLUSION
¶70 We affirm the District Court’s determination that Allianz’s policy provides coverage for the Plywood Plant Building based upon its location within 1,000 feet of a covered building. We also affirm the District Court’s refusal to reform the Allianz policy. We reverse, however, the District Court’s award of “replacement cost” for those portions of the Plywood Plant Building that the Port had slated for demolition. We further remand to allow the District Court to calculate post-judgment interest owed to the Port for the damages owed under the policy.
¶71 Affirmed in part, reversed in part, and remanded for further proceedings consistent with this opinion.
