Technology and operations. Technology expenses consist primarily of personnel costs related to our programming staff who develop and deploy new marketplaces and continuously enhance existing marketplaces. These personnel also develop and upgrade the software systems that support our operations, such as sales processing. Because our marketplaces and support systems require frequent upgrades and enhancements to maintain viability, we have determined that the useful life for certain of our internally developed software is less than one year. As a result, we expense those costs as incurred. However, where we determine that the useful life of the internally developed software will be greater than one year, we capitalize development costs in accordance with ASC 350.
Operations expenses consist primarily of operating costs, including buyer relations, shipping logistics and distribution center operating costs.
Sales and marketing. Sales and marketing expenses include the cost of our sales and marketing personnel as well as the cost of marketing and promotional activities. These activities include online marketing campaigns such as paid search advertising.
General and administrative. General and administrative expenses include all corporate and administrative functions that support our operations and provide an infrastructure to facilitate our future growth. Components of these expenses include executive management and staff salaries, bonuses and related taxes and employee benefits; travel; headquarters rent and related occupancy costs; and legal and accounting fees. The salaries, bonus and employee benefits costs included as general and administrative expenses are generally more fixed in nature than our operating expenses and do not vary directly with the volume of merchandise sold through our marketplaces.
Amortization of contract intangibles. Amortization of contract intangibles expense consists of the amortization of our contract intangibles associated with the Jacobs Trading acquisition on October 1, 2011, and the NESA transaction on November 1, 2012. The intangible asset created in conjunction with the acquisition of Jacobs Trading was valued at $33.3 million and was being amortized over 55 months on a straight-line basis. The amortization period was correlated to the base term of the Wal-Mart contract from the acquisition date, exclusive of renewal periods. Upon the early termination of the Wal-Mart contract in December 2014, we expensed the remaining amount of unamortized expense of approximately $10.3 million during the three months ended December 2014. The vendor contract intangible asset created in conjunction with the NESA acquisition was valued at $3.9 million and was being amortized over 20 months, on a straight-line basis. The amortization period was correlated to the base term of the contract, from the acquisition date, exclusive of renewal periods.
Depreciation and amortization. Depreciation and amortization expenses consist primarily of the depreciation and amortization of amounts recorded in connection with the purchase of furniture, fixtures and equipment and amortization of intangible assets from our acquisitions.
Acquisition costs and related fair value adjustments and impairment of goodwill and long-lived assets. Acquisition costs and related fair value adjustments and impairment of goodwill and long-lived assets consist of expenses incurred to complete a business combination, adjustments to the fair value of earn-outs, and impairment of goodwill and long-lived assets.
Interest (income) expense and other expense, net. Interest (income) expense and other expense, net consists of interest income on the note receivable related to the sale of the Jacobs Trading Company, expenses related to our terminated credit facility, and impacts of foreign currency fluctuations.
Income taxes. For interim income tax reporting the Company estimates its annual effective tax rate and applies this effective tax rate to its year to date pre-tax (loss) income. The Companys effective income tax rate before discrete items was 28.6% and 22.8% for the six months ended March 31, 2016 and March 31, 2015, respectively. The 2016 effective tax rate differed from the statutory federal rate of 35.0% primarily as a result of the impact of foreign, state, and local income taxes and permanent tax adjustments. We expect our future years tax rates to be between 30% and 40%.
