Section 1 – Conflict Minerals Disclosure

Item 1.01 Conflict Minerals Disclosure and Report

GENERAL

National Instruments Corporation (“NI”, “we”, “us” or “our”) designs, manufactures and sells tools to engineers and scientists that accelerate productivity, innovation and discovery. Our graphical system design approach to engineering provides an integrated software and hardware platform that speeds the development of systems needing measurement and control. NI is based in Austin, Texas, was incorporated under the laws of the State of Texas in May 1976 and was reincorporated in Delaware in June 1994.

In 2010 the US Congress enacted the conflict minerals provisions of the Dodd-Frank Financial Reform legislation. The law’s aim is to curb violence and human rights abuses in the Democratic Republic of the Congo (DRC), the Republic of Congo, the Central African Republic, South Sudan, Uganda, Rwanda, Burundi, Tanzania, Zambia and Angola (collectively, the “Covered Countries”) by requiring disclosure of certain information by public companies that use certain minerals which are necessary to the functionality or production of their products, which minerals include gold, columbite-tantalite (coltan), cassiterite and wolfamite, including their derivatives which are limited to tantalum, tin and tungsten (collectively, the “Conflict Minerals”).

COVERED PRODUCTS

NI offers an extensive line of measurement and control products to work either separately, as stand-alone products, or as an integrated solution. NI’s hardware products include Data Acquisition Hardware, PXI Modular Instruments, Modular Instruments, Machine Vision/Image Acquisition, Motion Control, and NI LabVIEW Reconfigurable I/O (RIO) Architecture, Industrial Communications Interfaces, and GPIB Interface products.

Most NI hardware products contain at least one of the Conflict Minerals and fall into the scope of the law’s requirements; thus, this disclosure includes information on a company level basis that includes general information for all NI products.

Reasonable Country of Origin Inquiry Description

For calendar year 2015, NI has undertaken in good faith a reasonable country of origin inquiry reasonably designed to determine the country of origin of Conflict Minerals necessary to the functionality or production of NI Products.  The objective of the inquiry was to collect accurate, complete, and actionable Conflict Minerals data and information in support of the conflict minerals due diligence process from  applicable direct suppliers of components used to build NI’s hardware products.  

In connection with its inquiry, NI surveyed its direct suppliers by collecting suppliers' Conflict Minerals policy statements and/or Electronic Industry Citizenship Coalition (EICC)/Global e-sustainability Initiative (GeSI) Conflict Free Smelter (CFS) declarations. This data collection process included research of supplier websites, directly contacting suppliers via email, phone or facsimile as needed, and following up on any missing data or non-responsive suppliers.  NI then performed quality inspection on documents and information received from suppliers and validated the responses by reviewing the completeness of the survey, obtaining additional responses if necessary, resolving discrepancies (such as metal type, address, and contact info), if any, between smelters as provided by the supplier and EICC standard smelter list, and determining which smelters are validated as conflict-free as part of the Conflict-Free Smelter Program.
