Updated: 
The FTSE 100 finished almost 84 points lower on last week as a whole, at 6,499. Persimmon was Friday's biggest winner by a large margin up +8.30% to 1188p with Randgold Resources behind, climbing +5.32% to 5150p. BAE Systems took the heaviest loss, down -1.15% to 437.40p.

Overnight, the NIkkei 225 is up +0.53% to 13,722.
We start with engineering group AMEC and confirmation that AMEC is readying a grab for rival Kentz. The confirmed proposed AMEC offer is at 565 to 580 pence per Kentz share, a premium to Kentz's current share price (which has appreciated since AMEC made an earlier approach to Kentz on 11 July).

Shares in Kentz closed around +2% higher at the end of last week, at 475.9p. AMEC boss Samir Brikho had signalled recently that he was looking to snap up new acquisitions in the oil and gas area in the second half of the year.

"AMEC believes this opportunity is consistent with AMEC's strategy, as it would extend AMEC's geographic footprint in the Growth Regions, increase the range of services offered to clients, and enhance AMEC's position in two of its core markets; oil & gas and mining."

Next, interim numbers for the six months up to 30 June from insurer Amlin. Profits before tax are cut to £161.4 million (H1 2012: £184.4 million) while the first half return on equity of reduces to 9.3% (H1 2012: 11.9%). Gross written premiums rise to £1,838.9 million (H1 2012: £1,814.7 million).

Earnings per share slip to 28.2 pence (H1 2012: 34.1 pence). Amlin expects the overall trading environment to remain "satisfactory" for the remainder of 2013. Margin potential remains it says and its market position remains "strong". Amlin should also benefit from the underlying improvements in its European businesses, it claims.

"These are a solid set of results which demonstrate a good level of underlying underwriting profitability," says chief exec Charles Philipps. "There are positive trends in a number of our businesses which will counteract downward pressure on catastrophe reinsurance rates and this reinforces the benefit of our diversification strategy."

Lastly, better half-year numbers from Bovis. Housing revenues climb +17% to £183.2m overall. while house operating profit soars +50% to £20.4m. Operating profit is up +17% to £20.5m. Earnings per share climb +26% to 10.8p while the dividend per share rises +33% to 4.0p.

"With market house price increases," the company claims, "estimated at 1% to 2% to date, average sales price increased by 15% to £188,500 (H1 2012: £164,400) primarily due to mix, modestly ahead of Group's expectations."

There were 963 legal completions (H1 2012: 944 homes) and average active sales outlets increased +11% to 91 in H1 2013 (2012: 82). There were 2,767 consented plots on 18 sites added to the land bank during H1 2013.
