Item 2. PROPERTIES

At February 2, 2019, we operated a total of 1,717 stores, of which 1,480 were Ross stores in 38 states, the District of Columbia, and Guam, and 237 were dd’s DISCOUNTS stores in 18 states. All stores are leased, with the exception of two locations which we own.

During fiscal 2018, we opened 75 new Ross stores and closed four existing stores. The average approximate Ross store size is 28,000 square feet.

During fiscal 2018, we opened 24 new dd’s DISCOUNTS stores and closed no existing stores. The average approximate dd’s DISCOUNTS store size is 23,000 square feet.

During fiscal 2018, no one store accounted for more than 1% of our sales.

We carry fire, flood, wind, and earthquake insurance to help mitigate the risk of financial loss that may result from such events.

Our real estate strategy in 2019 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 2019. 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 2, 2019 and February 3, 2018.

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 2, 2019, 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 20 years if renewal options are included. See Note E of Notes to Consolidated Financial Statements.

The following table summarizes the location and approximate sizes of our distribution centers, warehouses, and office locations as of February 2, 2019.
