achieved through limit setting by product type criteria, such as industry, and identification of credit concentrations. As part of its normal business activities, the Company offers a broad array of lending products. The Company categorizes its loan portfolio into two segments, which is the level at which it develops and documents a systematic methodology to determine the allowance for credit losses. The Company’s two loan portfolio segments are commercial lending and consumer lending.
The commercial lending segment includes loans and leases made to small business, middle market, large corporate, commercial real estate, financial institution,
non-profit
and public sector customers. Key risk characteristics relevant to commercial lending segment loans include the industry and geography of the borrower’s business, purpose of the loan, repayment source, borrower’s debt capacity and financial flexibility, loan covenants, and nature of pledged collateral, if any, as well as macroeconomic factors such as unemployment rates, gross domestic product levels, corporate bond spreads and long-term interest rates, all of which have been impacted by the
COVID-19
pandemic. These risk characteristics, among others, are considered in determining estimates about the likelihood of default by the borrowers and the severity of loss in the event of default. The Company considers these risk characteristics in assigning internal risk ratings to, or forecasting losses on, these loans, which are the significant factors in determining the allowance for credit losses for loans in the commercial lending segment.
The consumer lending segment represents loans and leases made to consumer customers, including residential mortgages, credit card loans, and other retail loans such as revolving consumer lines, auto loans and leases, home equity loans and lines, and student loans, a
run-off
portfolio. Home equity or second mortgage loans are junior lien
closed-end
accounts fully disbursed at origination. These loans typically are fixed rate loans, secured by residential real estate, with a
10-
or
15-year
fixed payment amortization schedule. Home equity lines are revolving accounts giving the borrower the ability to draw and repay balances repeatedly, up to a maximum commitment, and are secured by residential real estate. These include accounts in either a first or junior lien position. Typical terms on home equity lines in the portfolio are variable rates benchmarked to the prime rate, with a
10-
or
15-year
draw period during which a minimum payment is equivalent to the monthly interest, followed by a
20-
or
10-year
amortization period, respectively. At June 30, 2021, substantially all of the Company’s home equity lines were in the draw period. Approximately $1.2 billion, or 12 percent, of the outstanding home equity line balances at June 30, 2021, will enter the amortization period within the next 36 months. Key risk characteristics relevant to consumer lending segment loans primarily relate to the borrowers’ capacity and willingness to repay and include unemployment rates, consumer bankruptcy filings and other macroeconomic factors, customer payment history and credit scores, and in some cases, updated
(“LTV”) information reflecting current market conditions on real estate-based loans. These and other risk characteristics, including risk resulting from the
COVID-19
pandemic, are reflected in forecasts of delinquency levels, bankruptcies and losses which are the primary factors in determining the allowance for credit losses for the consumer lending segment.
The Company further disaggregates its loan portfolio segments into various classes based on their underlying risk characteristics. The two classes within the commercial lending segment are commercial loans and commercial real estate loans. The three classes within the consumer lending segment are residential mortgages, credit card loans and other retail loans.
The Company’s consumer lending segment utilizes several distinct business processes and channels to originate consumer credit, including traditional branch lending, mobile and
on-line
banking, indirect lending, alliance partnerships, correspondent banks and loan brokers. Each distinct underwriting and origination activity manages unique credit risk characteristics and prices its loan production commensurate with the differing risk profiles.
Residential mortgage originations are generally limited to prime borrowers and are performed through the Company’s branches, loan production offices, mobile and
on-line
services and a wholesale network of originators. The Company may retain residential mortgage loans it originates on its balance sheet or sell the loans into the secondary market while retaining the servicing rights and customer relationships. Utilizing the secondary markets enables the Company to effectively reduce its credit and other asset/liability risks. For residential mortgages that are retained in the Company’s portfolio and for home equity and second mortgages, credit risk is also diversified by geography and managed by adherence to LTV and borrower credit criteria during the underwriting process.
The Company estimates updated LTV information on its outstanding residential mortgages quarterly, based on a method that combines automated valuation model updates and relevant home price indices. LTV is the ratio of the loan’s outstanding principal balance to the current estimate of property value. For home equity and second mortgages, combined
(“CLTV”) is the
