(Sharecast News) - RPC's director of finance opted on Thursday to play it safe, selling a large packet of shares in the packaging supplier the day before Berry Group told the market that it would not be tabling a higher takeover offer, unless the company received a better bid from someone else.Earlier in March, Berry had offered 793p a share for the UK plastics manufacturer - which the RPC board went on to recommend to its shareholders - beating out a previous bid from US private equity giant Apollo, that was made on 23 January and which was worth 782p a share.Kesterton, who had been the company's finance chief since May 2013, sold 65,000 shares - at 796p each - on Thursday for a total transaction amount of £516,868.Top Director BuysRestore (RST)Director name: Skinner,CharlesAmount purchased: 16,802 @ 298.50pValue: £50,153.97Duke Royalty Limited (DUKE)Director name: Cannon-Brookes,CharlesAmount purchased: 100,000 @ 43.60pValue: £43,600.00Renishaw (RSW)Director name: Lee,William Amount purchased: 1,000 @ 3,793.00pValue: £37,930.00Alba Mineral Resources (ALBA)Director name: Frangeskides,GeorgeAmount purchased: 8,333,333 @ 0.30pValue: £25,000.00Alba Mineral Resources (ALBA)Director name: Nott,MichaelAmount purchased: 6,666,667 @ 0.30pValue: £20,000.00Zambeef Products (ZAM)Director name: Mwanza,JacobAmount purchased: 173,333 @ 10.50pValue: £18,199.96Zambeef Products (ZAM)Director name: Mwanza,JacobAmount purchased: 100,000 @ 10.50pValue: £10,500.00Jpmorgan American Inv Trust (JAM)Director name: Collins,Alan Amount purchased: 2,271 @ 437.48pValue: £9,935.17Cropper (james) (CRPR)Director name: Maddock,IsabelleAmount purchased: 968 @ 973.00pValue: £9,418.64Zambeef Products (ZAM)Director name: Mwanza,JacobAmount purchased: 26,296 @ 10.50pValue: £2,761.08Sse (SSE)Director name: Pibworth ,Martin Amount purchased: 36 @ 1,215.11pValue: £437.44Sainsbury (j) (SBRY)Director name: Rogers,JohnAmount purchased: 49 @ 234.99pValue: £115.15Top Director SellsRpc Group (RPC)Director name: Kesterton,SimonAmount sold: 65,000 @ 795.18pValue: £516,867.64Greggs (GRG)Director name: Hutton,RichardAmount sold: 1,150 @ 1,861.00pValue: £21,401.50Greggs (GRG)Director name: Hutton,RichardAmount sold: 1,100 @ 1,861.00pValue: £20,471.00Cropper (james) (CRPR)Director name: Maddock,IsabelleAmount sold: 1,113 @ 966.00pValue: £10,751.58Cropper (james) (CRPR)Director name: Maddock,IsabelleAmount sold: 162 @ 972.00pValue: £1,574.64
