We typically locate and engage third party property management service providers at our own expenses to provide services such as security, property maintenance, cleaning and other ancillary services to our tenants (the "Ancillary Services"). We generally enter into service agreements with these service providers with a term of one to three years. We usually renew such service agreements upon their expiration and we have never encountered any difficulty in finding such service providers in the past. We believe that such service providers are readily available in the market as the property management services industry is competitive. We also provide overall management of the operation of our integrated commercial complexes, including identifying the target customers and creating the image of the shopping malls, organizing the marketing campaigns and overseeing the overall operation (the "Overall Management Services").
