To calculate the NuBits in circulation, I will start with all 3,199,120 blockchain NuBits.

The following are tier 4 funds that should be excluded:
BhCnQrYrA5LZm871dtMQEXeU93gmqbhdrC: 2,000,000
B5Zi5XJ1sgS6mWGu7bWJqGVnuXwiMXi7qj: 150,000
BFTnCyMX1nsTNp6X7Bcm1qVocvShdbwtMi: 118,105
BqyRzFtWXDmjxrYpyJD42MLE5xc8FrB4js: 170,201
Using this method I arrive at 760,814 NBT in circulation.
15% of that sets the reserved tier 4 buy side funds at $114,122.
The BTC/USD exchange rate as of the end of Friday UTC was $456.63 (at Bitfinex).
Tier 4 buy side funds controlled by FLOT consisted of 183.09 BTC.
Tier 4 buy side funds controlled by @JordanLee consisted of 442.7 BTC.
Tier 4 buy side funds total 625.79 BTC (valued $285,755).
$114,1229 excluded from the share buyback calculation equals 249.92 BTC.
625.79 - 249.92 = 375.87 BTC sits in the share buyback pool.
10% of this (37.5 BTC) will be used for share buyback next week.
That is equivalent to approximately $17,123.
This will be the 14th weekly share buyback.
It is my understanding that FLOT will provide @NSRBuyback with the 37.5 BTC.
I ran out of time doing the calculation, but will initiate the transfer from FLOT to @NSRBuyback later if nobody beats me to it.
