NMI Holdings Inc (NMIH)

A. Company Overview

NMI Holdings Inc. (NMIH), a Delaware corporation established in May 2011, primarily operates through its subsidiary National Mortgage Insurance Corporation (NMIC) to provide mortgage insurance (MI). The company began its start-up operations in 2012 and issued its first MI policy in 2013. With its headquarters in Emeryville, California, NMI Holdings has expanded its customer portfolio significantly, establishing relationships with a diverse range of mortgage lenders across the United States.

The company operates within a highly regulated environment, principally under the jurisdiction of the Wisconsin Office of the Commissioner of Insurance (Wisconsin OCI), where both NMIC and another subsidiary, National Mortgage Reinsurance Inc One (Re One), are domiciled. NMIC is recognized as the primary insurance provider and is licensed to write MI coverage in all 50 states and Washington D.C. Its core mission is to mitigate mortgage credit risk, allowing lenders to finance a broader spectrum of potential homebuyers, particularly those utilizing high loan-to-value (LTV) mortgages.

As of December 31, 2023, NMI Holdings reported having issued master policies to 1,974 customers, which include national and regional mortgage banks, credit unions, community banks, and other non-bank lenders. The company's insurance-in-force amounted to $197.0 billion with a primary risk-in-force of $51.8 billion, and it generated new insurance written (NIW) of $40.5 billion in the same period.

NMI Holdings employs a workforce of 238 full-time and part-time employees who collectively drive the company's strategic objectives revolving around customer service excellence, robust risk management, and competitive pricing strategies.

B. Business Model

NMI Holdings operates primarily in the mortgage insurance sector, aimed at protecting lenders from potential losses due to borrower defaults. The MI insurance model plays a pivotal role in the U.S. housing market, particularly for loans with high LTV ratios — those where borrowers make down payments of less than 20%. This protection allows lenders to transfer a portion of their credit risk to the insurance provider, facilitating further lending and access to financing for prospective homeowners.

Mortgage insurance serves two primary functions: it allows mortgage lenders to sell high-LTV loans in the secondary market and supports government-sponsored enterprises (GSEs), which include Fannie Mae and Freddie Mac. This involvement incentivizes private capital participation and provides liquidity to the housing finance system.

NMIH's strategy integrates customer-centric approaches, including responsive service and innovative technology solutions, such as its proprietary Rate GPS® pricing platform, which helps assess and price risk dynamically. The company prioritizes the establishment of long-term relationships with customers to foster loyalty and service satisfaction.

C. Products and Services

NMI Holdings offers two main types of mortgage insurance products: primary and pool insurance.

Primary Mortgage Insurance

Primary MI covers individual mortgage loans based on specified coverage percentages. Policies are generally written on a flow basis, which means they are insured one-by-one at the time of origination. For loans that are sold to GSEs, the coverage levels must comply with established GSE requirements.

Coverage and Terms

• The coverage levels vary from 6% to 35%, with higher coverage resulting in higher premiums.
• The issuance of coverage is governed by the Master Policies, which outline eligibility criteria, coverage conditions, premium obligations, exclusions, and claims processes. The current Master Policy was implemented in March 2020 to enhance coverage terms and ensure compliance with updated GSE guidelines.

The premium structures include options for borrower-paid and lender-paid mortgage insurance, accommodating various loan structures and customer preferences.

Pool Insurance

NMIH's pool insurance provides credit enhancement for certain secondary market transactions. This type of insurance covers losses on loans that default beyond the initial claims paid under primary MI coverage, thereby offering an additional layer of protection.

In recent years, NMI Holdings has also collaborated with GSEs to provide customized MI solutions, although specific agreements have time limits, such as its pool agreement with Fannie Mae that expired in August 2023.

Loan Review Services

NMI Services, Inc. (NMIS), a subsidiary of NMIH, offers outsourced loan review services to ensure compliance with underwriting guidelines through data analysis and documentation reviews. This service is available for loans requiring MI as well as for those that do not.

D. Market Dynamics

The U.S. residential mortgage market is robust and complex, amounting to approximately $13 trillion as of the close of 2023. This market comprises primary components (direct home loan origination) and secondary components (mortgage trading and securitization). The participation spans various player types, including private mortgage lenders, commercial banks, credit unions, and government agencies.

The competitive landscape for NMI Holdings includes several other private MI providers, each striving for market share based on terms of coverage, pricing structures, customer service experience, and technological advancements. Following the financial crisis of 2008, government MIs significantly increased their presence in the market, which subsequently impacted the share held by private insurers. Over time, the market has stabilized, and government MIs were estimated to hold around 55% of the market share as of 2023.

E. Regulatory Framework

NMI Holdings and its subsidiaries are subject to rigorous oversight under both state and federal regulations governing the insurance and mortgage industries. Key regulatory bodies include state insurance departments and the GSEs, which impose compliance obligations to ensure the prudent management of capital, risk, and operational integrity.

Regulatory frameworks such as the PMIERs (Private Mortgage Insurer Eligibility Requirements) dictate the minimum asset requirements and operational standards for mortgage insurers approved by the GSEs. Additionally, the company is compliant with various consumer protection laws that ensure fair practices throughout the mortgage origination and services process.

F. Technology and Risk Management

A significant aspect of NMI Holdings' operational strategy involves the use of advanced technology systems. The AXIS platform is employed for underwriting and servicing, while the Rate GPS® pricing tool provides dynamic risk assessment capabilities to adjust premiums according to the risk profile of insured loans.

The Company has instituted a comprehensive enterprise risk management framework that encompasses credit market risk and operational risk. This rigorous approach to risk management ensures adherence to established underwriting guidelines and the continual monitoring of portfolio performance, thus maintaining the organization’s financial health amid fluctuating market conditions.

G. Investment Strategy

NMI Holdings actively manages its investment portfolio to ensure adequate liquidity and capital preservation. It primarily invests in investment-grade fixed-income securities and other short-term instruments. The company engages third-party investment managers to oversee portfolio performance in alignment with its investment policy, which emphasizes diversification and risk mitigation.

H. Human Capital

NMI Holdings employs a strategic approach to human capital management focused on attracting, developing, and retaining talented professionals. The workforce is essential to its operating efficiency and effectiveness in delivering high-quality service. Employee development initiatives and a comprehensive benefits package support the company's goal of maintaining a skilled and committed team, which is instrumental to achieving its strategic objectives.
