Our objective is to ensure that we have the right products from the leading manufacturers to build the end-in solutions for these systems. We seek new manufacture partners, there could also be complementary acquisitions and organic growth opportunities for [inaudible] profiteer products units which designs and manufactures the unmet needs. In addition to expanding the systems we support and products we offer, we focus on deepening and broadening our relationship with our manufacturing partners. During the last few months new opportunities with two important partners have emerged. Our largest vendor ComScore has reduced its wireless distribution phase naming Tessco as its one of four preferred US wireless distributing partners. We expect this to present us with the opportunity to gain share from those distributors who no longer offer ComScore products. In addition Samsung selected Tessco as its primary partner to market and offer their mobile device accessories to our enterprise customers. These growing relationships demonstrate the value we provide to both our customers and our manufacturing partners and we expect them to yield long term benefits. The last initiative I want to review is the expansion and enhancement of our digital marketing system which includes Tessco and Ventiv.Com and the one to one communications and opportunity creation in the sales guidance system.
This entire system is improving customer experience and providing Tessco with new opportunities and enhance productivity. Results from the system are emerging and we expect to see increasing benefits from this initiative on a daily basis. To better execute our digital and online efforts as well as traditional marketing we reorganized this digit-marketing group and appointed Craig Owen Vice-President as the group’s head and as a member of our senior leadership executive team reporting directly to me. Craig has brought leadership to the marketing organization and gain momentum in transforming our digital experiences and capabilities. He has a proven track record developing e-commerce platforms within integrated marketing and advertising programs built on customer insights and competitive differentiators. Craig joined Tessco in March 2014 and has an extensive experience of telecommunications, insurance and financial services industry, having served previously at Sprint PCS Ameritech now AT&T, Zurich financial services and American Red Cross. So I will now turn it over to Eric to continue the discussion. Eric!
Eric: Thanks Bob. As Bob mentioned the public carriers revenue is way down this quarter. But excluding that market overall revenue is still increased 5%. Although along with the softness in the carrier space, we saw declines in gross profit and operating margin. Gross profit margin was down compared to last year’s third-quarter, declining from 24.9% to 24.1%. We experienced higher trading cost this quarter primarily associated with out ventiv products. These costs resulted from labor incapacity issues with the west coast ports as well as a constraint supply by iPhone connectors that are used in our chargers. The increase in inventory write-off reserves is due in parts to some aging inventory relating to the carrier slow-down and cell phone cases associated with older phone models.
