EXECUTIVE OVERVIEW
Summary of 2019 Third Quarter Results Compared to 2018 Third Quarter
For the quarter, we reported net income of $372 million, or $0.34 per common share, compared with $378 million, or $0.33 per common share, in the year-ago quarter (see Table 1).
Fully-taxable equivalent net interest income was $805 million, down $5 million, or 1%. This reflected a 12 basis point decrease in the FTE net interest margin to 3.20%, partially offset by the benefit from the $2.9 billion, or 3%, increase in average earning assets.
The provision for credit losses increased $29 million year-over-year to $82 million in the 2019 third quarter. Net charge-offs increased $44 million to $73 million. The increase was centered in two specific energy credit relationships, which made up nearly three-fourths of the total commercial net charge-offs. Consumer charge-offs have remained consistent over the past year. NCOs represented an annualized 0.39% of average loans and leases in the current quarter, up from 0.16% in the year-ago quarter.
Non-interest income was $389 million, up $47 million, or 14%, from the year ago quarter. Mortgage banking income increased $23 million, or 74%, primarily reflecting higher overall salable spreads, and $8 million of income from net MSR risk management-related activities. Capital markets fees increased $10 million, or 38%, driven by increased underwriting activity primarily associated with the Hutchinson, Shockey, Erley & Co. acquisition. Card and payment processing income increased $7 million, or 12%, and service charges on deposit accounts increased $5 million, or 5%, both reflecting increased account activity.
Non-interest expense was $667 million, up $16 million, or 2%, from the year-ago quarter. Personnel costs increased $18 million, or 5%, primarily reflecting a shift to colleagues supporting our core strategies and the implementation of annual merit increases in the 2019 second quarter. Outside data processing and other services increased $18 million, or 26%, primarily driven by higher technology investment costs. Deposit and other insurance expense decreased $10 million, or 56%, due to the discontinuation of the FDIC surcharge in the 2018 fourth quarter. Other expense decreased $9 million, or 16%, primarily as a result of operational losses in the third quarter 2018.
Common Equity Tier 1 risk-based capital ratio was 10.02%, up from 9.89% a year ago. The regulatory Tier 1 risk-based capital ratio was 11.41% compared to 11.33% at September 30, 2018. All capital ratios were impacted by the repurchase of 33.4 million common shares over the last four quarters.

Business Overview
General
Our general business objectives are:
Consistent organic revenue and balance sheet growth.
Invest in our businesses, particularly technology and risk management.
Deliver positive operating leverage.
Maintain aggregate moderate-to-low risk appetite.
Disciplined capital management.
Economy
Consumer confidence remains at a high level, and consumers continue to perform well. We experienced strong origination activity in our home lending and auto finance businesses, while maintaining our underwriting discipline. Consistent with recent economic data pointing toward slowing growth, compounded by uncertainty related to trade and tariffs, we have seen a shift in tone from some of our manufacturing customers, which has impacted certain of their investments and expansions. While our commercial loan pipeline remains consistent with a year ago, providing us near-term confidence, we have a more measured outlook for commercial loan growth over the medium term.
As we have stated the past few quarters, we do not foresee a recession in the near term. Our core earnings power, strong capital, aggregate moderate-to-low risk appetite, and long-term strategic alignment position us to withstand economic headwinds should they emerge.
DISCUSSION OF RESULTS OF OPERATIONS

2019 Third Quarter versus 2018 Third Quarter
FTE net interest income for the 2019 third quarter decreased $5 million, or 1%, from the 2018 third quarter. This reflected a 12 basis point decrease in the NIM to 3.20%, partially offset by the benefit from the $2.9 billion, or 3%, increase in average earning assets. The NIM compression reflected a 23 basis point increase in average interest-bearing liability costs, partially offset by a 5 basis point year-over-year increase in average earning asset yields and a 6 basis point increase in the benefit from noninterest-bearing funds. The increase in average interest-bearing liability costs primarily reflects higher interest bearing deposit costs (up 25 basis points). The increase in earning asset yields was primarily driven by higher consumer loan yields as securities yields were relatively flat (up 1 basis point) and commercial loans decreased modestly (down 5 basis points). Embedded within these yields and costs, FTE net interest income during the 2019 third quarter included $11 million, or approximately 4 basis points, of purchase accounting impact compared to $17 million, or approximately 7 basis points, in the year-ago quarter.
Average earning assets for the 2019 third quarter increased $2.9 billion, or 3%, from the year-ago quarter, primarily reflecting a $2.3 billion, or 3%, increase in average loans and leases. Average C&I loans increased $1.8 billion, or 6%, reflecting growth in corporate banking, asset finance, and dealer floorplan. Average residential mortgage loans increased $1.0 billion, or 10%, driven by the successful expansion of our home lending business within our existing markets and the lower rate environment. Average RV and marine loans increased $0.5 billion, or 17%, reflecting market share increases across our markets, while maintaining our commitment to super prime originations. Held-for-sale and other earning assets increased $0.7 billion, or 86%, primarily due to the inclusion of deposits in Federal Reserve Bank balances. These balances were treated as non-earning assets prior to the fourth quarter 2018. Partially offsetting these increases, average home equity loans and lines of credit decreased $0.5 billion, or 5%, reflecting a shift in consumer preferences.
Average total interest-bearing liabilities for the 2019 third quarter increased $2.3 billion, or 3%, from the year-ago quarter. Average total deposits increased $0.8 billion, or 1%, from the year-ago quarter, while average total core deposits increased $1.7 billion, or 2%. Average money market deposits increased $2.7 billion, or 13%, reflecting the shift in promotional pricing to consumer money market accounts in mid-2018. Average core certificates of deposit increased $0.8 billion, or 15%, reflecting consumer deposit growth initiatives in the third quarter of 2018. Savings and other domestic deposits decreased $1.8 billion, or 15%, primarily reflecting a continued shift in consumer product mix. Average brokered deposits and negotiable CDs decreased $0.9 billion, or 26%, as growth in core deposits reduced reliance on wholesale funding.
2019 Third Quarter versus 2019 Second Quarter
Compared to the 2019 second quarter, FTE net interest income decreased $13 million, or 2%, primarily reflecting the NIM compression of 11 basis points, partially offset by a 1% increase in average earning assets. The NIM contraction reflected a 14 basis point decrease in average earning asset yields and a 3 basis point decrease in average interest-bearing liability costs. The decrease in earning asset yields was primarily driven by the impact of lower LIBOR rates in the quarter on commercial loan yields. The decrease in average interest-bearing liability costs primarily reflects lower short-term borrowing costs. The purchase accounting impact on the NIM was approximately 4 basis points in the 2019 third quarter, down 1 basis point from the prior quarter.
Average earning assets increased $0.5 billion, or 1%, from 2019 second quarter. Average consumer loans were relatively unchanged, as modest increases in residential mortgage and RV and marine loans were largely offset by a decline in home equity loans.
Average total interest-bearing liabilities increased $0.2 billion, or less than 1%. Average total deposits increased $0.5 billion, or 1%, as the $1.0 billion, or 4%, increase in money market accounts more than offset the $0.4 billion, or 4%, decrease in savings deposits, primarily reflecting promotional money market pricing and a continued shift in consumer product mix. Reflecting changes in the wholesale funding mix, average long-term debt increased $0.6 billion, or 7%, due to the $0.8 billion senior note issuance in August, while average short-term borrowings decreased $0.8 billion, or 26%.
