254 Notes to the consolidated financial statements of Aegon N.V.  Note 42 The difference between the contractually required payment at maturity date and the carrying amount of the borrowings amount to  EUR 55 million (2012: EUR 67 million). There were no defaults or breaches of conditions during the period. The provisions mainly consist of provisions for contingent consideration relating to joint ventures (earn out) of EUR 57 million  (2012: EUR 187 million), restructuring provisions of EUR 39 million (2012: EUR 56 million), provisions for unearned commission of  EUR 33 million (2012: EUR 33 million) and litigation provisions of EUR 23 million (2012: EUR 10 milion).  The contingent consideration relating to joint ventures reflects earn out payments, which will be payable if specific targets, as set out  in the purchase agreements, are met in the future. The expected timing of resulting outflows vary between 2014 and 2017. In 2013, Disposals contain a release of an earn out provision in Spain of EUR 120 million as Aegon has finalized exiting its joint  venture with Unnim. In 2012 Disposals contain a release of an earn out provision in Spain of EUR 38 million relating to the disposal of  the Banca Civica joint venture. In 2012, Other reflects the release of earn out provisions relating to Caja Cantabria. Refer to note 25 for more details.
