Oct 10 (Reuters) - The following bids, mergers, acquisitions and disposals were reported by 1115 GMT on Monday:
** The asset management arm of insurer Swiss Life SLHN.S is buying Mayfair Capital, a London-based property investment and management company with a portfolio valued at around 1 billion pounds ($1.24 billion), Mayfair said. Saudi Arabia Fertilizers Co 2020.SE and Saudi Basic Industries Corp 2010.SE have hired investment banks to advise on the potential sale of a stake in the Ibn Al-Baytar fertilizer company. Private equity firm HabourVest HVPEa.L offered to buy smaller rival SVG Capital's SVI.L investment portfolio, providing an alternative to its $1.35 billion cash offer for the company, as it looks to trump an already accepted offer from Goldman Sachs (NYSE:GS) GS.N and the Canada Pension Plan Investment Board. French tycoon Vincent Bollore said his investment company had raised its stake in Vivendi VIV.PA to above 20 percent, further tightening his hold on the French media group. Swedish buyout firm EQT, which acquired 69 percent of BSN medical in 2012 for 1.8 billion euros ($2.02 billion), hired JP Morgan earlier this year to handle the sale, in a deal expected to be worth more than 2 billion euros ($2.24 billion). Canadian online gambling company Amaya Inc AYA.TO AYA.O and British bookmaker William Hill Plc WMH.L said they were in talks to combine in a merger of equals.
