I believe our digital business model, strong capital position, and robust funding channels will allow us to operate effectively during the downturn and position us well for the recovery.”

Actions taken in response to COVID-19:

• Enabled nearly 100% of employees to work from home

• Enhanced employee support programs

• Funded incremental community support

• Established "Skip-a-Payment" programs for impacted customers

• Implemented actions to mitigate impact of pandemic on future credit performance

• Identified $400 million of planned expense reductions

• Suspended share repurchase program

Segment Results:

Direct Banking

Direct Banking pretax loss of $161 million for the quarter was $1.0 billion lower than pretax income for the prior year period driven by an increase in the provision for credit losses and higher operating expenses partially offset by higher net interest income.

Total loans ended the quarter at $93.0 billion, up 5% year-over-year. Credit card loans ended the quarter at $73.8 billion, up 4% year-over-year. Personal loans increased $223 million, or 3%, year-over-year. Private student loans increased $355 million, or 4%, year-over-year. The organic student loan portfolio, which excludes purchased loans, increased $719 million, or 9% year-over-year.

Net interest income for the quarter increased $93 million, or 4%, from the prior year period, primarily driven by higher average loans slightly offset by net interest margin compression. Net interest margin was 10.21%, down 25 basis points versus the prior year period. Card yield was 12.90%, a decrease of 52 basis points from the prior year period primarily driven by prime rate

decreases partially offset by favorable portfolio mix. Interest expense as a percent of total loans decreased 39 basis points from the prior year period, primarily as a result of lower market rates.

The 30+ day delinquency rate for credit card loans was 2.62%, up 17 basis points year-over year and flatfrom the prior quarter. The credit card net charge-off rate was 3.65%, up 15 basis points from the prior year and up 24 basis points from the prior quarter. The student loan net charge-off rate was 0.68%, up 2 basis points from the prior year and down 34 basis points from the prior quarter. The personal loans net charge-off rate of 3.59% was down 94 basis points from the prior year and down 67 basis points from the prior quarter. The overall net charge-off rate was higher primarily due to the seasoning of recent years' loan growth.

Provision for credit losses of $1.8 billion increased $998 million from the prior year period driven by the impact of a higher reserve build and higher net charge-offs. The reserve build for the first quarter of 2020 was $1.1 billion, compared to a reserve build of $94 million in the first quarter of 2019. The company adopted CECL on January 1st of this year, and this quarter’s reserve build reflects the CECL reserve methodology, and an updated macroeconomic outlook.

Total operating expenses were up $129 million year-over year primarily as a result of increases in employee compensation, marketing, professional fees and information processing. Employee compensation increased as a result of higher average salaries and headcount. Marketing expenses increased as a result of higher investment in brand awareness and consideration. Professional fees increased primarily in connection with achieving a higher level of recoveries and information processing increased due to investments in technology capabilities and infrastructure.

Payment Services

Payment Services pretax income was $83 million in the quarter, up $32 million year-over-year, primarily driven by a one-time gain on the sale of an equity investment.

Payment Services volume was $63.9 billion, up 5% year-over-year. PULSE dollar volume was up 4% year-over-year, which reflects the impact of growth from existing issuers and acquirers, as well as new issuing and acquiring relationships. Network Partners volume increased by 23% year-over-year driven by AribaPay.

Share Repurchases

During the first quarter of 2020, the company repurchased approximately 4.7 million shares of common stock for $343 million. The company suspended the share repurchase program in March. Shares of common stock outstanding declined by 1.2% from the prior quarter.

Adoption of Accounting Standard for Measurement of Credit Losses

The company’s results for the first quarter 2020 reflect the January 1, 2020 effectiveness of Accounting Standards Update No. 2016-13, Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments for the Company (the “ASU”). For purposes of calculating the company’s regulatory capital, the company has elected to defer recognition of the estimated impact of the ASU on regulatory capital for two years in accordance with the interim final rule adopted by federal bank regulatory agencies on March 27, 2020. Pursuant to the interim final rule, the estimated impact of the ASU on regulatory capital will be phased in over a three year period beginning in 2022.
