What is the company's current return on invested capital
 Investor Day event on March 23 in which we unveiled several growth initiatives that we believe will help us continue our track record of above-market growth through a combination of organic and inorganic opportunities. Our organic opportunities are focused on expansion into new markets within our core competencies of wood and concrete products. Our inorganic opportunities will be focused on licensing, purchasing IP and traditional M&A.
As a reminder, our growth initiatives focused on the following markets, which I'll list in no particular order of priority: OEM, original equipment manufacturers; repair remodel, the do-it-yourself market; mass timber, concrete and structural steel. In order to appropriately grow in the first three markets that being OEM, retail -- R&R as well as the DIY and mass timber, we aspire to be a leader in engineered load-rated construction fastener solutions, given that each of these markets have a broader product opportunity within the fastener solutions.
In addition, we're striving to be a stronger leader in customer-facing technology, which has been a focus of ours for a number of years. Here I'm referring to software that helps our customers better run their business by providing them with the proper tools to design, select and specify the right Simpson solutions for the job. We expect technological advancements will drive enhanced growth in all of our key growth initiatives as well as across all of Simpson Manufacturing in general.
We believe our business model will support our ability to be successful throughout each of these areas, given our engineering expertise, our deep-rooted relationship with top builders, engineers, contractors, code officials and distributors, along with our ongoing commitment to testing, research and innovation. Importantly, we currently have existing products, test results, distribution and manufacturing capabilities for all five of our growth initiatives. This is also important to note that these initiatives are currently in different stages of development.
Our successful growth in these areas will ultimately be a function of expanding our sales and marketing functions to promote our products to different end-users and distribution channels, expanding our customer base, and potentially introducing new products in the future. We will keep you appraised of significant updates regarding our key growth initiatives as they arise.
I'd also like to highlight our five-year Company ambitions that we unveiled at our Analyst Investor Day. First, we want to strengthen our values-based culture. Barclay Simpson founded our Company on the nine principles of doing business, which continue to guide our organization today. Our Simpson Strong-Tie employees are our most important asset. So we spend a significant amount of time communicating with them to ensure a relentless customer focus, involving them in leadership programs and instilling a safety-first culture.
Second, we want to be the partner of choice. This ambition takes on many meanings. It means we want to be your solution provider, your trusted brand to provide you a solution and quickly get that product out to your job site and we want to make it easy to do business with us. We aspire to be the partner of choice in all aspects of our business.
Third, we strive to be an innovative leader in product categories. If we can accomplish this, we have no doubt we will be able to accomplish ambition Number 4, which is to continue our above-market growth relative to U.S. housing starts. This we will continue to expand our operating income margin to remain within the top quartile of our proxy peers. And finally, we will continue expanding our return on invested capital to remain in the top quartile of those peers. After building our strong foundation through the 2020 plan, we look forward to an even stronger future ahead.
Before I close today, I'd like to briefly touch on our capital allocation strategy. As our business continues to generate strong cash flows, we remain focused on appropriately balancing our growth and stockholder
