What Is a SASB Loan and How Does It Work?

While the term “SASB loan” is not a formal, standardized financial product, it generally refers to a type of sustainability-linked financing where loan terms are connected to a borrower’s environmental, social, and governance (ESG) performance. These arrangements often leverage the Sustainability Accounting Standards Board (SASB) standards to define and measure sustainability progress.

Defining SASB-Linked Financing

SASB-linked financing is a form of sustainability-linked loan (SLL) where the financial terms, typically the interest rate, adjust based on the borrower’s achievement of predetermined sustainability performance targets (SPTs). Unlike green loans, which dictate how the loan proceeds must be used for specific environmentally friendly projects, SLLs offer flexibility, allowing funds to be used for general corporate purposes. This distinction makes SLLs accessible to a broader range of industries and companies.

Companies that meet or exceed their sustainability targets may benefit from lower interest rates, while failure to meet these targets can lead to increased rates. This financial incentive drives borrowers to embed sustainability deeper into their business models.

Sustainability Accounting Standards Board (SASB) standards play a significant role in this type of financing due to their focus on financially material sustainability issues. SASB provides industry-specific standards across 77 industries, identifying the most relevant environmental, social, and governance topics that can impact a company’s financial performance and enterprise value. By aligning with SASB standards, companies can demonstrate their commitment to measurable and transparent sustainability practices, which is increasingly valued by investors and lenders.

Key Structural Elements

Central to this structure are Key Performance Indicators (KPIs) and Sustainability Performance Targets (SPTs). These KPIs are measurable benchmarks, such as greenhouse gas emissions reduction, water usage efficiency, or improvements in diversity metrics. Lenders and borrowers collaboratively select typically two to three quantitative KPIs that are relevant, material, and measurable to the borrower’s core business.

Once KPIs are established, ambitious yet achievable SPTs are set for each, outlining the specific levels of improvement the borrower aims to reach within the loan’s duration. The loan agreement then incorporates a margin ratchet mechanism, where the interest rate adjusts based on whether these SPTs are met or missed. For instance, if a company achieves its targets, the interest rate may decrease, providing a financial reward. Conversely, if targets are not met, the interest rate can increase, creating a financial consequence.

Interest rate adjustments, often referred to as step-downs for achieving targets and step-ups for missing them, typically range from 5 to 25 basis points (0.05% to 0.25%). Some loan structures may include only a step-down, offering only upside potential, while others feature two-way adjustments with both incentives and penalties. The loan documentation specifies the frequency of performance assessment, often annually, and the corresponding interest rate changes.

External verification of the borrower’s performance against the agreed-upon KPIs and SPTs is a mandatory component of sustainability-linked loans. This verification is conducted by independent third parties, such as sustainability auditors or ESG rating agencies, to ensure credibility and transparency. The verification process typically involves assurance, attestation, or certification, confirming the accuracy of reported sustainability data. This independent review provides assurance to lenders and investors that the company’s sustainability claims are robust and its progress is genuine.

Preparing for SASB-Linked Financing

Companies considering SASB-linked financing must undertake thorough internal preparation to ensure a smooth process and successful outcome. A foundational step involves comprehensively assessing the company’s current sustainability performance. This assessment should identify existing environmental, social, and governance (ESG) efforts and benchmark them against relevant industry-specific SASB standards. Understanding the current state allows a company to pinpoint areas for improvement and realistically set future targets.

Establishing robust data collection and management systems is paramount. Sustainability-linked loans require consistent and accurate tracking of performance against chosen KPIs. Companies need to have reliable internal processes for gathering, monitoring, and reporting sustainability data, particularly those metrics aligned with SASB’s financially material issues. Investing in specialized software tools can significantly streamline this data collection and help ensure data quality and accuracy.

Developing strong reporting capabilities is also essential. Companies must be able to transparently report their sustainability performance to potential lenders. This includes not only the raw data but also clear explanations of methodologies and progress. Having internal expertise in sustainability reporting, potentially supported by external consultants, can enhance the credibility of these reports.

Identifying and setting ambitious yet achievable sustainability performance targets is a collaborative effort between the company and potential lenders. These targets should be integrated into the company’s overall business strategy and reflect meaningful improvements in its sustainability profile. The targets must be quantifiable and verifiable to be effective in the loan agreement.

Achieving internal alignment across various departments is a final, but important, preparatory step. Finance, sustainability, operations, and legal teams must work together to support data collection, target achievement, and reporting requirements. This cross-functional collaboration ensures that the company is fully prepared to commit to and deliver on the sustainability objectives tied to the loan.
