Reclassifications, adjustments and other includes the exchanges of wireless licenses in 2015 and 2014 as well as $0.3 billion of Wireless licenses that are classified as Assets held for sale on our consolidated balance sheets at December 31, 2015 and 2014, respectively. See Note 2 for additional details.

At December 31, 2015 and 2014, approximately $10.4 billion and $0.4 billion, respectively, of wireless licenses were under development for commercial service for which we were capitalizing interest costs. The increase is primarily due to licenses acquired in the AWS-3 auction.

The average remaining renewal period of our wireless license portfolio was 5.6 years as of December 31, 2015. See Note 1 for additional details.

As a result of the acquisition of AOL in the second quarter of 2015, we recognized preliminary Goodwill of $1.9 billion, which is included within Other (see Note 2 for additional details). We also allocated $0.6 billion of goodwill on a relative fair value basis from Wireline to Other as a result of an internal reorganization. This increase was partially offset by a decrease in Goodwill in Wireline primarily due to the reclassification of $1.3 billion of Goodwill to Non-current assets held for sale on our consolidated balance sheet at December 31, 2015 as a result of our agreement to sell our local exchange business and related landline activities in California, Florida and Texas to Frontier (see Note 2 for additional details). The amount of Goodwill reclassified was based on a relative fair value basis.
