Let's get rolling here, and I won't spend any time on the forward-looking statement. You all know that very well. We are going to cover a number of topics today, and we've done this before. A number of times, we've talked about our vision and strategy. We will get into some detail about our assets and well we are positioned we'll talk about our track record and commitment to disciplined growth and we'll talk about our proven ability to create value for all of our stakeholders.
Touching on our vision, we over the past decade, whether it's through internal projects or acquisitions have been the result of executing our vision. Two main points about our vision, we have re-bundled services across the value chain to provide our customers with premium services. We have also applied our capabilities as a natural gatherer, transporter and marketer and distributor to other products in particular natural gas liquids and crude oil. We do this while providing non-discretionary services to our producers, our processor customers, which means the services are required to get their products to market. We'll talk about that here in a bit more detail and what I mean by non-discretionary services.
Our key strategies include growing ONEOK Partners, which is our primary growth engine and we are two-thirds of each incremental EBITDA dollar at ONEOK Partners is return to ONEOK's cash, enabling ONEOK to continue to grow it's free cash flow. For opportunities such as potentially growing the ONEOK dividend by 40% from 2012 to 2014, and buying back ONEOK shares and we'll talk some more about that here in a moment.
We've successively improved our returns at ONEOK's three regulated utilities and continue to shrink our contracted transportation and storage capacity at our energy services business while rebasing our cost structure there. We continue to evaluate acquisition opportunities that either of the entities and we do this while maintaining a strong balance sheet and investment grade credit ratings at both, ONEOK and ONEOK Partners.
