OPINION AND ORDER
Shira A. Scheindlin, U.S.D.J.:This is an appeal from an order entered in the jointly administered chapter 11 *678bankruptcy cases of appellees Genco Shipping & Trading Limited and related entities (together, “Genco”) disallowing the claims of appellants Fisher Brothers Management Co. LLC (“Fisher Management”) and Fisher-Park Lane Owner LLC (“Fisher-Park”). For the reasons set forth below, the Bankruptcy Court’s order disallowing appellants’ claims is VACATED and this matter is REMANDED to the Bankruptcy Court for further proceedings consistent with this Opinion and Order.
I. BACKGROUND
A. The Lease Documents
The facts relevant to this appeal are undisputed. Pursuant to a Master Lease dated September 22, 2005, Genco leased office space on the twentieth floor of 299 Park Avenue from Fisher-Park.1 In January 2012, Genco vacated the twentieth floor and moved its headquarters to the twelfth floor of the same building.2 Under a Sublease dated November 1, 2013, Genco subleased the twentieth-floor office space to Fisher Management. The annual rent payable to Genco under the Sublease was less than the annual rent Genco paid to Fisher-Park under the Master Lease.3
Section 5.1 of the Sublease provides that, “[i]f the [Master Lease] shall terminate for any reason this Sublease shall also terminate as of the date of termination of the [Master Lease], unless [Fisher-Park] otherwise agrees, and in no event shall [Genco] be liable therefor.” Section 5.1 also states that:
Notwithstanding the foregoing, [Genco] may otherwise voluntarily terminate the [Master Lease] without [Fisher Management’s] consent if [Fisher-Park] agrees to assume and accept this Sublease in order to permit [Fisher Management] to remain in possession of the Subleased [premises as a direct tenant for the remainder of the term of the Sublease or pursuant to- a new direct lease between [Fisher-Park] and [Fisher Management].
The same day the Sublease was executed, Genco, Fisher-Park, and Fisher Management entered into a consent to the Sublease (the “Consent”) and a Subordination, Nondisturbance, and Attornment Agreement (the “SNDA Agreement”; together with the Master Lease, Sublease, and Consent, the “Lease Documents”). Recital 3 of the SNDA Agreement states that Fisher Management “was unwilling to enter into the Sublease absent [Fisher-Park’s] execution of [the SNDA Agreement] and [the C]onsent ... pursuant to which [Fisher-Park] has consented to the Sublease.” Section 2(b) of the SNDA provides that:
In the event the [Master] Lease terminates for any reason other than (i) the occurrence of a casualty or condemnation that results in the exercise by [Fisher-Park] of a termination right under the [Master] Lease or (ii) a default by [Fisher Management] or breach of [Fisher Management’s] obligations under the Sublease, then so long as [Fisher Management] is not then in default in the performance of any of its obligations under the Sublease ....
[Fisher Management’s] subleasehold estate in the [twentieth floor] shall not be terminated or disturbed and the Sublease shall continue in full force and effect with respect to the Subleased Premises as a direct lease between *679[Fisher Management] and [Fisher-Park] upon all of the same terms, covenants, conditions and obligations of the Sublease (subject, however, to the other provisions of this Agreement) relative to the [twentieth floor] only, for the balance of the term thereof with the same force as if the Sublease were a direct lease between [Fisher-Park] and [Fisher Management]; provided, however, that, commencing oh the [date on which Fisher Management attorns to Fisher-Park and Fisher-Park recognizes the tenancy of Fisher Management], [Fisher Management] shall pay the greater of (x) the fixed annual rent and additional rent as provided in the Sublease, or (y) the fixed annual rent and additional rent as provided in the [Master Lease],
B. Appellants’ Claims
On April 21, 2014, Genco commenced a chapter 11 bankruptcy case. That same day, Genco filed a motion to reject the Lease Documents.4 After a hearing, the Bankruptcy Court entered an order approving the rejection (the “Lease Rejection Order”).5 This order was entered on consent of appellants.6
On May 20, 2014, Fisher-Park filed a proof' of claim seeking an unspecified amount of unpaid rent as a consequence of the rejection of the Master Lease. That same day, Fisher Management filed a proof of claim seeking $1,614,130.33 in damages based on the additional rent it was required to pay following Genco’s rejection of the Sublease.7 Genco filed an objection to appellants’ claims.
The Bankruptcy Court issued a decision disallowing appellants’ claims in their entirety.8 It held that Fisher-Park had not suffered any damages because it had continued to receive — from Fisher Management — the full rental amount previously paid by Genco.9 It further held that Fisher Management did not have a claim for damages because it had received what it had bargained for under the Lease Documents — “the benefit of undisturbed occupancy, rather than [having to] face potential eviction .... ”10
II. LEGAL STANDARD
A district court functions as an appellate court in. reviewing orders entered by bankruptcy courts.11 Findings of fact are reviewed for clear error, whereas findings that involve questions of law, or mixed questions of fact and law, are reviewed de novo.12
III. APPLICABLE LAW
A. Lease Rejection and Claim Allowance
Under section -365(a) of the Bankruptcy Code, “subject to the court’s *680approval, [the debtor-in-possession] may assume or reject any executory contract or unexpired lease of the debtor.” Subsection (g) states that “the rejection of an executo-ry contract or unexpired lease of the debt- or constitutes a breach of such contract or lease ... [which is deemed to occur] immediately before the date of the filing of the petition —” As explained by. the Second Circuit:
Rejection gives rise to a remedy for breach of contract in the non-debtor party. The claim is treated as a pre-petition claim, affording creditors their proper priority. Under sections 365(g) and 502(g), the date of breach is set as the date immediately prior to the debtor’s filing for bankruptcy. See also 4 Collier § 502.08[2], The Bankruptcy Code treats rejection as a breach so that the non-debtor party will have a viable claim against the debtor. However, the Code does not determine parties’ rights regarding the contract and subsequent breach. To determine these rights, we must turn to state law.13
Section 502(g)(l)states that:
A claim arising from the rejection, under section 365 of this title or under a plan under chapter 9, 11, 12, or 13 of this title, of an executory contract or unexpired lease of the debtor that has not been assumed shall be determined, and shall be allowed under subsection (a), (b), or (c) of this section or disallowed under subsection (d) or (e) of this section, the same as if such claim had arisen before the date of the filing of the petition.
Section 101(5)(A) of the Bankruptcy Code defines “claim” as a “right to payment, whether or not such right is reduced to judgment, liquidated, unliquidated, fixed, contingent, matured, unmatured, disputed, undisputed, legal, equitable, secured, or unsecured ....” Under section 501(a), “a creditor ... may file a proof of claim,” and under section 502(a), such claim will be deemed allowed unless an objection is filed.14 One basis for sustaining an objection and disallowing a claim is that “such claim is unenforceable against the debtor and property of the debtor, under any agreement or applicable law for a reason other than because such claim is contingent or unmatured .... ”15 “Applicable law” most often refers to state law.16
B. Contract Interpretation
Under New York law, “[t]he court’s function in interpreting a contract *681is to apply the meaning intended by the parties, as derived from the language of the contract in question;”17 “[T]he best evidence of what parties to a written agreement intend is what they say in their writing. Thus, a written agreement that is complete, clear and unambiguous on its face must be enforced according to the plain meaning of its terms.”18
“The question of whether a written contract is ambiguous is a question of law for the court.”19 “Contract language is unambiguous when it has a definite and precise meaning, unattended by danger of misconception in the purport of the contract itself, and concerning which there is no reasonable basis for a difference of opinion.”20 However, contract language is ambiguous if “the terms of the contract could suggest more than one meaning when viewed objectively by a reasonably intelligent person who has examined the context of the entire integrated agreement and who is cognizant of the customs, practices, usages and terminology as generally understood in the particular trade or business.”21
IY. DISCUSSION
Appellants argue that because (1) section 365(g)(1) states that a rejection constitutes a breach and (2) it is axiomatic that a breach entitles the non-breaching party to a remedy (whether or not the governing contract specifically provides for such remedy), they are entitled to damages.22 Appellants concede “that common law damages for breach of contract are not recoverable where the contract at issue anticipates the possible occurrence of such breach and provides for a specific remedy in the event of such occurrence.”23 According to appellants, however, “there is nothing contained in any of the Lease Documents that even remotely contemplates a unilateral breach by Genco of the Sublease or disclaims damages therefor in the event such unilateral breach ever occurred.”24
According to the Bankruptcy Court, two provisions of the Lease Documents “compelled] the conclusion that Genco is not obligated to pay any amounts sought in the two Claims.”25 The Bankruptcy Court believed that “[s]ection 2 of the SNDA specifically addresses the exact circumstances now before the Court. It makes clear that, where the Master Lease is terminated, but the subtenant [ ] stays in the premises, the subtenant must pay the full amount of the *682rent.”26 The Bankruptcy Court also relied on section 5.1 of the Sublease, which provides that “[i]f the [Master Lease] shall terminate for any reason this Sublease shall also terminate as of the date of the termination of the [Master Lease], unless [Fisher-Park] otherwise agrees, and in no event shall [Genco] be liable therefor.”
However, the Second Circuit explains that “[w]hile rejection [under section 365(g)(1)] is treated as a breach, it does not completely terminate the contract. Thus, rejection merely frees the estate from the obligation to perform; it does not make the contract disappear.”27 It follows that the Master Lease (and the other Lease Documents) were not “terminated” solely by virtue of Genco’s rejection of those agreements. Accordingly, the Bankruptcy Court has either erred by equating rejection with termination or by failing to make a finding of fact that Genco terminated either the Master Lease or the Sublease. As a consequence, it is unclear whether or not the termination language in section 2 of the SNDA and section 5.1 of the Sublease apply to this case. Likewise, the Bankruptcy Court failed to address “breach” under section 365(g)(1) and whether and to what extent the Lease Documents contemplated a breach by Gen-co.
Because it is unclear from the Bankruptcy Court Opinion, and from the order itself, to what extent the Bankruptcy Court relied on erroneous legal conclusions or findings of fact in ruling on the claim objections, the Bankruptcy Court’s order must be vacated.28 On remand the Bankruptcy Court is directed to address appellants’ arguments — based on section 365(g)(1) and the Lease Documents — that the rejection of the Lease Documents “constituted .... a breach of the Sublease by Genco, thereby entitling [ ] Fisher Management to damages arising from' such breach.”29 In so doing, the Bankruptcy Court should consider the meaning of “breach” in section 365(g)(1), the interplay between such a breach and determining a claim under section 502(g)(1), and the defenses to liability for breach of a lease under New York law. The Bankruptcy Court is further directed to determine the damages, if any, arising from Genco’s breach of the parties’ agreements. In addition to the above, the Bankruptcy Court may address any other issues it deems necessary to resolving the claims objections,
V. CONCLUSION
Accordingly, the Bankruptcy Court’s order disallowing appellants’ claims is VACATED and this matter is REMANDED to the Bankruptcy Court, for further proceedings consistent with this Opinion and Order. The Clerk of the Court is directed to close this appeal.
