12.	Sales of Intangible Assets

During fiscal year 2015, we sold two blocks of non-strategic IPv4 addresses to two buyers for a total of $737. These blocks of IPv4 addresses, which were recorded at $0 book value, have not been a material part of our ongoing operations. The aggregate gain on the sales of these IPv4 addresses of $664 is net of broker fees of $73 incurred to consummate the transaction.

During fiscal year 2013, we sold certain non-strategic patents and patent applications (collectively known as “intellectual property”) for $2,750 in cash. We originally acquired this intellectual property in the purchase of Everstream, Inc. (“Everstream”) but did not expect to use the technology associated with this intellectual property as part of our ongoing or planned operations. As a result, this intellectual property was originally valued at $0 upon our acquisition of Everstream. The gain on the sale of the intellectual property of $2,381 is net of $369 of commissions and legal fees that were incurred as a result of the sale, and would not have been incurred otherwise.
