- Mortgage Segment: Delivered $221 million in underwriting income, with credit quality remaining strong despite modest growth in mortgage originations.
- Investment Income: Contributed $408 million or $1.13 per share, with a decline attributed to lower cash yields and seasonal compensation payouts.
