As the volume of consumer and commercial lending applications has steadily increased, banks and credit unions have focused on coping with their disparate lending systems and the need to improve the speed of decisions. Investments in a new generation of loan origination systems are now a key area of strategic focus for financial institutions as they look to reduce costs and grow revenue.

In the Webinar, "Emerging Trends and Best Practices in Enterprise Lending," featuring Cornerstone Advisors' Steve Williams, attendees will learn how to strategically impact lending operations through:

--Real-world examples of how institutions are beginning to re-engineer their lending environments to take advantage of new technological capabilities.

--Key factors that financial institutions are using to select loan origination technology.

--Best practices being employed to get a tangible return on these technology investments.

In addition to the main presentation, S1 will highlight its new consumer and commercial lending solutions. At the conclusion, both speakers will be available to respond to questions from attendees in a live Q&A session.
