Merchandise.
The merchandising strategy for Walmart International is similar to that of our operations in the U. S.  in terms of the breadth and scope of merchandise offered for sale.
While brand name merchandise accounts for a majority of our sales, we have both leveraged U. S.  private brands and developed market specific private brands to serve our customers with high quality, low priced items.
Along with the private brands we market globally, such as "Equate," "George," "Great Value," "Holiday Time," "Mainstays," "Marketside," and "Parent's Choice," our international markets have developed market specific brands including "Aurrera," "Cambridge," "Lider," "Myntra," "Jabong," "PhonePe," and "Extra Special. "
In addition, we have developed relationships with regional and local suppliers in each market to ensure reliable sources of quality merchandise that is equal to national brands at low prices.
Operations.
The hours of operation for operating units in Walmart International vary by country and by individual markets within countries, depending upon local and national ordinances governing hours of operation.
Operating units in each country accept a variety of payment methods.
Seasonal Aspects of Operations.
Walmart International's business is seasonal to a certain extent.
Historically, the segment's highest sales volume and operating income have occurred in the fourth quarter of our fiscal year.
The seasonality of the business varies by country due to different national and religious holidays, festivals and customs, as well as different weather patterns.
Competition.
Walmart International competes with omni-channel retailers who operate department, drug, discount, variety and specialty stores, supermarkets, hypermarkets and supercenter-type stores, wholesale clubs, home-improvement stores, specialty electronics stores, cash & carry operations and convenience stores, and eCommerce retailers, as well as catalog businesses.
Our ability to develop, open and operate units at the right locations and to deliver a customer-centric omni-channel experience largely determines our competitive position within the retail industry.
We believe price leadership is a critical part of our business model and we continue to focus on moving our markets towards an EDLP approach.
Additionally, our ability to operate food departments effectively has a significant impact on our competitive position in the markets where we operate.
Distribution.
We utilize a total of 226 distribution facilities located in Argentina, Canada, Central America, Chile, China, Japan, Mexico, South Africa, India and the United Kingdom.
Through these facilities, we process and distribute both imported and domestic products to the operating units of the Walmart International segment.
During fiscal 2019, approximately 83% of Walmart International's purchases passed through these distribution facilities.
Suppliers ship the balance of Walmart International's purchases directly to our stores in the various markets in which we operate.
We ship merchandise purchased by customers on our eCommerce platforms by a number of methods from multiple locations including from our 90 dedicated eCommerce fulfillment centers, as well as more than 1,900 eCommerce sort centers in India.12 Sam's Club Segment Sam's Club operates in 44 states in the U.

The Retail Industry We operate in the highly competitive omni-channel retail industry in all of the markets we serve.
We face strong sales competition from other discount, department, drug, dollar, variety and specialty stores, warehouse clubs and supermarkets, as well as eCommerce businesses.
Many of these competitors are national, regional or international chains or have a national or international omni-channel or eCommerce presence.
We also compete with a number of companies for attracting and retaining quality employees ("associates").
We, along with other retail companies, are influenced by a number of factors including, but not limited to: catastrophic events, weather, competitive pressures, consumer disposable income, consumer debt levels and buying patterns, consumer credit availability, cost of goods, currency exchange rate fluctuations, customer preferences, deflation, inflation, fuel and energy prices, general economic conditions, insurance costs, interest rates, labor costs, tax rates, the imposition of tariffs, cybersecurity attacks and unemployment.
Further information on the factors that can affect our operating results and on certain risks to our Company and an investment in its securities can be found herein under "Item 1A.
Risk Factors," and under "Cautionary Statement Regarding Forward-Looking Statements. "32 Company Performance Metrics We are committed to helping customers save money and live better through everyday low prices, supported by everyday low costs. ?
At times, we adjust our business strategies to maintain and strengthen our competitive positions in the countries in which we operate. ?
We define our financial framework as: ?
strong, efficient growth; ?
consistent operating discipline; and ?
strategic capital allocation.
As we execute on this financial framework, we believe our returns on capital will improve over time.
Strong, Efficient Growth Our objective of prioritizing strong, efficient growth means we will focus on the most productive growth opportunities, increasing comparable store and club sales, accelerating eCommerce sales growth and expansion of omni-channel initiatives while slowing the rate of growth of new stores and clubs.
At times, we make strategic investments which are focused on the long-term growth of the Company.
Comparable sales is a metric that indicates the performance of our existing stores and clubs by measuring the change in sales for such stores and clubs, including eCommerce sales, for a particular period over the corresponding period in the previous year.
The retail industry generally reports comparable sales using the retail calendar (also known as the 4-5-4 calendar).
To be consistent with the retail industry, we provide comparable sales using the retail calendar in our quarterly earnings releases.
However, when we discuss our comparable sales below, we are referring to our calendar comparable sales calculated using our fiscal calendar, which may result in differences when compared to comparable sales using the retail calendar.
Calendar comparable sales, as well as the impact of fuel, for fiscal 2019 and 2018, were as follows:
