To calculate the NuBits in circulation, I will start with all 3,047,774 blockchain NuBits. The following are tier 4 funds that should be excluded:
BhCnQrYrA5LZm871dtMQEXeU93gmqbhdrC: 2,000,000
B5Zi5XJ1sgS6mWGu7bWJqGVnuXwiMXi7qj: 150,000
BFTnCyMX1nsTNp6X7Bcm1qVocvShdbwtMi: 134,100
Using this method I arrive at 763,674 NBT in circulation. 15% of that sets the reserved tier 4 buy side funds at 114,551.
The BTC/USD exchange rate as of the end of Friday UTC was $363.70. Tier 4 buy side funds consisted of 714 BTC valued at $259,698. $114,551 excluded from the share buyback calculation equals 315 BTC. 399 BTC sits in the share buyback pool. 10% of this (39.9 BTC) will be used for share buyback next week. That is equivalent to approximately $14512. This will be the 11th weekly share buyback.
It is my understanding that FLOT will provide @NSRBuyback with the 39.9 BTC.
