Home equity – Home equity lending includes both home equity loans and lines-of-credit.
This type of lending, which is secured by a first-lien or junior-lien on the borrower’s residence, allows customers to borrow against the equity in their home or refinance existing mortgage debt.
Products include closed-end loans which are generally fixed-rate with principal and interest payments, and variable-rate, interest-only lines-of-credit which do not require payment of principal during the 10-year revolving period.
The home equity line of credit may convert to a 20-year amortizing structure at the end of the revolving period.
Applications are underwritten centrally in conjunction with an automated underwriting system.
The home equity underwriting criteria is based on minimum credit scores, debt-to-income ratios, and LTV ratios, with current collateral valuations.
The underwriting for the floating rate lines of credit also incorporates a stress analysis for a rising interest rate.
Residential mortgage – Residential mortgage loans represent loans to consumers for the purchase or refinance of a residence.
These loans are generally financed over a 15-year to 30-year term, and in most cases, are extended to borrowers to finance their primary residence.
Applications are underwritten centrally using consistent credit policies and processes.
All residential mortgage loan decisions utilize a full appraisal for collateral valuation.
Huntington has not originated or acquired residential mortgages that allow negative amortization or allow the borrower multiple payment options.
RV and marine finance – RV and marine finance loans are loans provided to consumers for the purpose of financing recreational vehicles and boats.
Loans are originated on an indirect basis through a series of dealerships across 26 states.
The loans are underwritten centrally using an application and decisioning system similar to automobile loans.
The current portfolio includes 60% of the balances within our core footprint states.
Other consumer – Other consumer loans primarily consists of consumer loans not secured by real estate, including personal unsecured loans, overdraft balances, and credit cards.
The table below provides the composition of our total loan and lease portfolio: Table 9 - Loan and Lease Portfolio Composition (dollar amounts in millions)

In consumer lending, credit risk is managed from a segment (i. e. , loan type, collateral position, geography, etc. )
and vintage performance analysis.
All portfolio segments are continuously monitored for changes in delinquency trends and other asset quality indicators.
We make extensive use of portfolio assessment models to continuously monitor the quality of the portfolio, which may result in changes to future origination strategies.
The ongoing analysis and review process results in a determination of an appropriate ALLL amount for our consumer loan portfolio.
The independent risk management group has a consumer process review component to ensure the effectiveness and efficiency of the consumer credit processes.
Collection actions by our customer assistance team are initiated as needed through a centrally managed collection and recovery function.
We employ a series of collection methodologies designed to maintain a high level of effectiveness, while maximizing efficiency.
In addition to the consumer loan portfolio, the customer assistance team is responsible for collection activity on all sold and securitized consumer loans and leases.
Collection practices include a single contact point for the majority of the residential real estate secured portfolios.
AUTOMOBILE PORTFOLIO Our strategy in the automobile portfolio continues to focus on high quality borrowers as measured by both FICO and internal custom scores, combined with appropriate LTVs, terms, and profitability.
Our strategy and operational capabilities allow us to appropriately manage the origination quality across the entire portfolio, including our newer markets.
Although increased origination volume and entering new markets can be associated with increased risk levels, we believe our disciplined strategy and operational processes significantly mitigate these risks.
We have continued to consistently execute our value proposition and take advantage of available market opportunities.
Importantly, we have maintained our high credit quality standards while expanding the portfolio.
RESIDENTIAL REAL ESTATE SECURED PORTFOLIOS The properties securing our residential mortgage and home equity portfolios are primarily located within our geographic footprint.
Huntington continues to support our local markets with consistent underwriting across all residential secured products.
The residential-secured portfolio originations continue to be of high quality, with the majority of the negative credit impact coming from loans originated in 2006 and earlier.
Our portfolio management strategies associated with our Home Savers group allow us to focus on effectively helping our customers with appropriate solutions for their specific circumstances.
