Quantitative Government Support Overlay for Local Government Financing Vehicles (LGFVs) 1.0

Highlights

An Overlay Model Specializing in the Analysis of LGFVs in the China Domestic Market

Introduction

In China, most local and regional governments (LRGs) are not allowed to raise debt directly from the bond market.[1] As a result, they set up LGFVs as separate entities to engage in public service mandates, such as infrastructure and land development, and to perform related financing functions. Most of the infrastructure investments cannot generate enough profit to cover the cost in the short term, or even in the long term, thus LGFVs rely heavily on the LRG’s support, ultimately the LRG’s revenue. However, the support may be selective depending on many factors, such as the availability of resources and the number of peers in the same region. To evaluate the overall credit risk profile of an LGFV, it is necessary to assess the credit quality of the LRG and the likelihood of extraordinary government support.[2]

An LGFV is a special type of government-related entity (GRE), or an entity potentially affected by extraordinary government intervention in an economic or financial stress scenario. There are some differences between LGFVs and Non-LGFV GREs:

  • LGFVs have much closer linkages with the corresponding LRGs.
  • The main business of an LGFV is public service.
  • LGFVs’ debts are non-self-supporting.
  • LGFVs typically do not have cross-region business.
  • LGFVs are smaller in size.
  • LGFVs enjoy stronger support from governments.

Because of these differences and the importance of LGFVs in the China credit market, S&P Global Market Intelligence developed a quantitative support overlay model to assess the credit risk of LGFVs in an automated and scalable way.[3]

Extraordinary Government Support

The assessment of the likelihood of extraordinary government support for a particular LGFV starts with the assessment of two major dimensions: the importance of an LGFV’s role to the government and the strength of the link between the government and an LGFV.

The importance of an LGFV’s role to the LRG is classified into one of three categories:

  • Critical
  • Very Important
  • Important

The strength of the link between an LGFV and the LRG is classified into one of two categories:

  • Integral
  • Very Strong

Once these two factors are assessed, the likelihood of extraordinary government support can be obtained with a Role-Link Matrix in line with the S&P Global Ratings’ rating criteria.

Purpose and Scope of the Model

The goal of the quantitative overlay is to use a standardized, automated, transparent, and consistent process to assess the importance of the LGFV’s role to the underlying LRG, the strength of the link between the LGFV and the underlying LRG, and the likelihood of extraordinary government support.

The overlay applies to entities that are classified as LGFVs based on the following criteria:

  • Controlled by local governments.
  • Primarily deliver public services.
  • Not financially self-supportive or dependent on subsidies from the LRG.

Methodology

A decision tree algorithm is employed for this overlay because of the simple classification rules, robust performance, and high interpretability. A decision tree is a hierarchical model composed of decision rules, which are applied recursively to partition the feature space of a dataset into pure, single-class subspaces. Decision tree algorithm is used to discover features and extract patterns that are important for discrimination and predictive modeling. Moreover, decision tree algorithm is easy to understand with intuitive interpretation.

Final Credit Score Adjustment

The credit quality of an LGFV is not linked to the credit quality of a central government directly but with an LRG, since the central government's support for LGFV sector is a system-wide phenomenon, rather than entity specific. The assessments of government support for LGFVs therefore focus on the credit quality of an LRG instead of a central government.

The overlay implements the Role-Link Matrix (shown in Table 1) for mapping the “importance” and “link” to the likelihood of support, and then adjusts the LGFV’s credit score based on the estimated likelihood and the credit quality of the corresponding LRG.

For most cases, the impact of government is positive but, in some rare cases, the impact of government can be negative when an LRG has poorer credit qualities than an LGFV. Under a situation of financial stress, an LRG may intervene to redirect an LGFV’s resources to the government and weaken the LGFV's credit quality.

Performance

The overlay model, trained on S&P Global Ratings, aims to assess a potential uplift or downgrade of the stand-alone credit score of an entity due to potential extraordinary government support. One of the most intuitive measures of relative model performance is obtained by looking at the difference between the model outcome and S&P Global Ratings credit ratings. To validate the model performance, we compared the results of applying the overlay on the stand-alone credit scores generated by CreditModelTM 3.0 (CM 3.0) with the issuer credit ratings from the S&P Global Ratings’ research database.

Table 2 reports the percentage notch difference between the estimated scores and the actual ratings, based on the model training sample. The table shows that adding the government support overlay significantly enhances the ratings agreement for LGFVs.

Case Study

Company X is an LGFV in Beijing providing a range of public services, including metro investment and operation, land development, and toll road investment and operation. According to an S&P Global Ratings report, the strength of the link between the company and the Beijing government is integral because of robust government control over the business and the important public services being provided. The role of the company to the Beijing government is critical, since its infrastructure project is “too big to fail”.

Table 3 below compares the government support assessment between S&P Global Ratings and the quantitative LGFV overlay.

We see that the outcomes of the quantitative LGFV overlay model match well with the S&P Global Ratings assessment for this specific case.

Conclusion

S&P Global Market Intelligence has built a quantitative government support overlay model for the LGFV sector in the China domestic market. The model was trained on S&P Global Ratings data. It aims to produce differentiated credit score outputs and to offer an automated and scalable solution for gauging the credit risk of LGFVs, some of the largest bond issuers in China.
