One of our fastest growing products is Easy Flex. It’s an alternative to the block and index product. It allows you to take advantage of the index market— and also lock in a fixed price for up to 100% of your usage, should you choose. This is accomplished through a price lock.

You can make multiple fixed-price percentage purchases as opposed to a single fixed-price purchasing decision. This approach is akin to “dollar-cost-averaging” in your 401K. Easy Flex allows you to “dollar-cost-average” your way into a fixed-price position, giving you the price certainty that you want.
