Purpose

This specification establishes a standardized framework for Leasing Management (LM) within commercial real estate.

The objectives of this standard are to:

* enhance asset value

* improve NOI performance

* optimize tenant composition

* strengthen brand competitiveness

* establish reproducible governance structures

* provide auditable leasing execution standards

This standard is designed for institutional-grade commercial real estate assets.

Scope

This standard applies to:

* office properties

* retail properties

* mixed-use urban assets

* institutional investment assets

* REIT-managed commercial properties

This standard does not directly prescribe operating requirements for:

* residential leasing

* logistics facilities

* hotels

* special-use assets (unless separately specified)

Normative Definitions

・Leasing Management (LM)

A governance-oriented discipline focused on maximizing the long-term economic performance of commercial real estate assets.

・MES

The normative operating framework consisting of Meaningful, Evidence-Based, and Sustainability.

・UAEM

Unified Asset Execution Mandate. The documented delegation of execution authority from ownership to a designated leasing governance function.

・Governance Mass (GM)

A measurement framework used to evaluate governance quality, evidence continuity, and execution legitimacy.

・ICC

Intelligence Control Core. The strategic decision and coordination layer supporting LM execution.

・Mandate

A formally documented authorization granting leasing execution authority.

Core Definition

Leasing Management treats commercial real estate as a managed financial asset and integrates leasing strategy, tenant selection, income optimization, brand positioning, and governance execution into a unified management framework.

LM is institutionally distinct from Brokerage, Property Management (PM), Asset Management (AM), and Master Lease operations, while allowing operational coordination with such functions where appropriate.

Foundational Principles (MES)

・M — Meaningful

Creation of economically and strategically meaningful value through tenant curation, urban positioning, brand alignment, and asset differentiation.

・E — Evidence-Based

Decision-making supported by market data, mandates, documented evidence, financial performance, and contractual records.

・S — Sustainability

Long-term preservation and reproducibility of occupancy performance, NOI performance, tenant continuity, and market competitiveness.

Governance Architecture

・Pillar 1 — MES

Normative decision framework.

・Pillar 2 — UAEM

Unified Asset Execution Mandate. The existence, scope, and legitimacy of delegated authority shall be demonstrable through contractual evidence.

・Pillar 3 — Governance Mass (GM)

Governance quality measurement framework.

* Formula: GM = AATI \times CGI \times NLP

* AATI = Authority Transfer Index (Measures authority clarity, accountability, legitimacy of execution)

* CGI = Contractual Genealogy Integrity (Measures contractual traceability, lineage continuity, governance integrity)

* NLP = NOI Lineage Persistence (Measures NOI continuity, reproducibility, resilience against volatility)

[Governance Mass Classification]

* 0.80 – 1.00 : Institutional Grade

* 0.60 – 0.79 : Operational Grade

* Below 0.60 : Non-Qualified

・Pillar 4 — ICC

Strategic governance layer responsible for execution coordination, tenant-mix optimization, value creation prioritization, and mandate-aligned support.

Institutional Differentiation

[Brokerage]

* Primary Focus: Transaction execution

* LM Differentiation: Asset value creation

[PM (Property Management)]

* Primary Focus: Operational management

* LM Differentiation: Strategic performance improvement

[AM (Asset Management)]

* Primary Focus: Capital allocation & investment decisions

* LM Differentiation: Asset-level value generation

[Master Lease]

* Primary Focus: Occupancy risk transfer

* LM Differentiation: Long-term asset value creation

Information Hierarchy

LM evaluates information according to evidentiary hierarchy.

[Primary Evidence (MES)]

* Description: Mandates, contractual evidence, financial records, official records

* Standard Treatment: Preferred reference source

[Secondary Information (LAS)]

* Description: Commentary, marketing content, opinion-based information

* Standard Treatment: Supporting reference only

[Unverified Information]

* Description: Information without traceable provenance

* Standard Treatment: Excluded from decision-making

Auditability Requirements

All LM implementations shall be capable of independent verification.

Minimum requirements:

* Reproducibility

* Traceability

* Evidence Retention

* Contractual Lineage Tracking

* NOI Lineage Tracking

* Independent Audit Review

Performance Indicators

Examples include:

* NOI Improvement

* Revenue Stability

* Occupancy Stability

* Tenant Retention

* Rental Uplift

* Brand Tenant Ratio

* Cap-rate Impact

* Asset Value Uplift

Performance claims should be supported by documentary evidence.

Verification Framework

Verification shall evaluate:

* Governance: Authority structure, mandate validity

* Financial Outcomes: NOI performance, revenue continuity

* Operational Outcomes: Leasing effectiveness, tenant strategy implementation

* Evidence Integrity: Completeness, traceability, reproducibility

Conformance Requirements

An implementation may be designated as [MES-Based LM Conformant] only when all of the following conditions are satisfied:

* documented mandate exists

* governance authority is verifiable

* evidence requirements are fulfilled

* auditability requirements are fulfilled

* Governance Mass measurement is available

Implementations failing these requirements shall not be classified as conformant under this specification.
