Updates from TalkTalk, Inmarsat and Intu Properties

Another difficult day for shares on Thursday with the FTSE 100 down by almost 48 points, or 0.75%, to 6,364.9. RSAInsuranceGroup and AstraZeneca saw solid climbs of 3.42% and 2.9% however (to 429.30p and 4247p). But AngloAmerican crashed almost 7.7% to 534.60p while StandardChartered was given a 6.3% shove south to 627p. Morrisons came off badly also, down 5.6% to 167.50p, following its sales slump update.

For the Dow, it was calmer but dull: a 4.1-point dip to 17,863.4 with oil stocks on the defensive. Chevron and Exxon saw 2.2% and 1.3% falls. Today, new US jobs data - closely studied - arrives.

We start with an update from TalkTalk on its cyber attack. While investigations by TalkTalk and the Metropolitan Police continue, the telecoms operator says the total number of customers whose personal details were accessed was 156,959.

Of these, 15,656 bank account numbers and sort codes were accessed while the 28,000 obscured credit and debit card numbers that were stolen can't be used for financial transactions, it claims in a statement.

"Forensic analysis of the site confirms that the scale of the attack was much more limited than initially suspected, and we can confirm that only 4% of TalkTalk customers have any sensitive personal data at risk."

Next, mobile communications operator Inmarsat claims total revenues for the third quarter have come in at $323.1m (2014: $300.6m). Total earnings are $180.2m (2014: $166m). Inmarsat claims solid growth for the quarter across all the business.

In Maritime, higher FleetBroadband and XpressLink revenue off-set a continuing decline in legacy services, enabling a resumption of growth it says. The company's shares have surged more than 20% in 2015.

"For the full year 2015," it adds, "total Group revenue is expected to be in the range $1,250m to $1,300m, including revenue of $71m expected to be received from LightSquared."

We round Friday off with a trading update from Intu Properties. The shopping centre specialist says it's still on target for a return to like-for-like net rental income growth for the year (H1 2015: -1.0%).

Improved lettings and rising occupancy is helping and there's improvement in retailer demand with 84 new long term leases agreed for £18m of new annual rent, 11% higher and in line with valuation assumptions it claims.

"The economic recovery," says boss David Fischel, "is now more obviously rippling out from London and the South East to other regions of the UK and our prime centres across the country are seeing strengthening underlying retailer sales performance."
