Item 2. PROPERTIES

At February 3, 2018, we operated a total of 1,622 stores, of which 1,409 were Ross stores in 37 states, the District of Columbia, and Guam, and 213 were dd’s DISCOUNTS stores in 16 states. All stores are leased, with the exception of two locations which we own.

During fiscal 2017, we opened 74 new Ross stores and closed five existing stores. The average approximate Ross store size is 28,200 square feet.

During fiscal 2017, we opened 22 new dd’s DISCOUNTS stores and closed two existing stores. The average approximate dd’s DISCOUNTS store size is 23,100 square feet.

During fiscal 2017, no one store accounted for more than 1% of our sales.

We carry earthquake insurance to help mitigate the risk of financial loss due to an earthquake.

Our real estate strategy in 2018 is to primarily open stores in states where we currently operate, to increase our market penetration and leverage overhead and advertising expenses as a percentage of sales in each market. We also expect to continue our store expansion in newer markets in 2018. Important considerations in evaluating a new store location in both newer and more established markets are the availability and quality of potential sites, demographic characteristics, competition, and population density of the local trade area. In addition, we continue to consider opportunistic real estate acquisitions.

The following table summarizes the locations of our stores by state/territory as of February 3, 2018 and January 28, 2017.

Where possible, we obtain sites in buildings requiring minimal alterations, allowing us to establish stores in new locations in a relatively short period of time at reasonable costs in a given market. At February 3, 2018, the majority of our stores had unexpired original lease terms ranging from three to ten years with three to four renewal options of five years each. The average unexpired original lease term of our leased stores is five years or 21 years if renewal options are included. See Note E of Notes to Consolidated Financial Statements.
