that they both offer higher speeds than the RFP for the NBN requires. Following Telstra's exclusion from the National Broadband Network bidding process Telstra's share price suffered the biggest one-day percentage fall in its history. NBN Co Limited signed a definitive agreement with Telstra on , estimated to be worth post-tax net present value, building upon the signing of a financial heads of agreement a year beforehand. Telstra agreed to "disconnect" its Internet customers from the copper and hybrid fibre-coaxial networks in areas where FTTP has been installed, and agreed to lease dark fibre, exchange space and ducts to NBN Co. As part of the agreement, Telstra would not be able to market their mobile network as an alternative to the NBN for a number of years. Telstra remains the owner of its networks. On 18 October 2011, Telstra shareholders overwhelmingly approved the deal. On 14 December 2014 it was announced that in a A$11b renegotiated deal Telstra will transfer ownership of its copper and hybrid fibre-coaxial (HFC) networks to NBN while disconnecting premises from these networks. This ownership allows NBN Co to use these networks "where it sees fit in for its multi-technology NBN rollout." David Thodey era (2010–2015) Under the leadership of David Thodey, Telstra embarked upon a transformation agenda to become more sales and service focused. As part of that, an ambitious customer service agenda was defined. In 2014, Telstra was named "most respected company" by the Australian Financial Review newspaper. Market share recovery Early in 2010, Telstra announced the creation of a $1 billion "fighting fund" to be used in a concerted effort to win back market share in key product categories. This effort seems to have paid off with strong sales momentum announced in February 2011. Customer service recovery As part of its new strategy, Telstra announced that its "goal is for customer service to be fundamental to everything we do". In August 2011, Telstra Digital announced expansion of customer service into social media with 24/7 coverage. By November 2012, Telstra claimed 140,000 live chats for the month and a growth rate of this service of 600% p.a. In October 2013, Telstra announced that it had grown its Live Chat workforce to 600 and its social media workforce to 30.
