According to the income statement last quartal includes:
Income: 104,622.45 BTC (mining: 33,020.91 BTC, hardware sales: 71,601.54 BTC)
Expenses: 20,109.31 BTC
Net income: 84,513.14 BTC
It's not all that clear which time span the report covers, so let's say 13 - 15 weeks to include all possibilities. This results in the following weekly averages:
Income per week: 6,974.83 - 8,047.88 BTC
Expenses per week: 1,340.62 - 1,546.87 BTC
Net income per week: 5,634.21 - 6,501.01 BTC
Mining a block rewards 25 BTC and 6 - 7 blocks are mined hourly, depending on the increase of the hashrate.
So there are 150 - 175 BTC mined each hour, 3,600 - 4,200 BTC each day and 25,200 - 29,400 BTC each week.
Or in total 327,600 - 382,200 BTC are mined in 13 weeks and 378,000 - 441,000 BTC in 15 weeks.
This means:
ASICMINER generated an income which equals 23.72 - 31.94 % of all mined coins in this quartal.
Subtracting the expenses (i.e. electricity and hardware cost) results in a net income of 19.16 - 25.80 % of all mined coins in this time frame.
The balance sheet shows that there are 5,484.66 BTC, 393,202.00 USD and 15,318,262.72 RMB in assets, whereby 5,484.66 BTC and 4,480,310.50 RMB are in form of cash.
With an exchange rate of 6.087 RMB/USD and 198.28 USD/BTC this equals:
ASICMINER owns assets with a BTC value of 20,159.64 BTC (with 9,196,81 BTC in cash)
Or converted to their USD value: 3,997,254.14 USD (with 1,823,544.13 USD in cash)
Or converted to their RMB value: 24,331,285.96 RMB (with 11,099,913.17 RMB in cash)
(104622-20109)*3/53 = 4876 BTC per week
which is 0.012 BTC per week per share, which is what we saw more or less.
This is an effective share of 15% of the network over the last quarter.
Not clear on the time period (which is very important) but this would indicate a quarter.
But, I'm having trouble reconciling it with the cashflow statement.
Notice also that expenses go down in BTC terms since the recent price rise.
Of course, past performance is no guarantee of future performance.
