Disgraced coal miner Bumi (BUMI) has finally published its 2012 financial results after a messy period trying to find missing money from its Indonesian subsidiaries. Yet the shares remain suspended until it can tighten up internal systems. Once they do resume trading, we wouldn't be surprised to see a large fall in the share price as the results make horrible reading. It has incurred a $1.369 billion write-down on one subsidiary; and a $815 million impairment on another unit. The price at which it sold coal in the first three months of 2013 was 19% down year-on-year, although there's some joy in a 27% rise in production.

Industrial conglomerate Smiths (SMIN) ticked down 0.9% to £13.78 after confirming it had received a preliminary approach for its Smiths Medical business.

North Sea heavy oil play Xcite Energy (XEL:AIM) gained 2.2% to 105.8p after it cancelled a rig contract to explore other options for the development of its Bentley field. Chief executive officer Rupert Cole says alternatives could 'further enhance the economics' of the project.

A substantial $1 million order from its Indian partner wasn't enough to shift the market's attention away from weak financial results from wireless controls microcap Cyan (CYAN:AIM). It reported declining sales and a £3.1 million operating loss. The shares fell 6% to 0.53p as the market fretted about Cyan's future which appears to be living on borrowed time given last year's £2.8 million cash outflow and just £1.6 million left in the bank.

Wasabi Energy (WAS:AIM) jumped 5% to 0.52p after securing a complicated $3.59 million funding deal for a new Asian market venture. Key plans to build 25 megawatt output from its patented Kalina Cycle power packs remain a distant hope, 2015 at the earliest.

Shares in micro cap beverages business Blavod Wines & Spirits (BES:AIM) were flat at 0.9p, despite positive news flow from the premium drinks play.

Furthermore, the £2.75 million cap flagged a three-year distribution deal with Hi-Spirits for BlackWood's, RedLeg Rum and Blavod Black Vodka across the UK and Ireland, a move which will enable management to focus on developing and marketing its owned brand portfolio.
