5 band resistor - value, watt and tolerance
This looks like a 0.15 ohm resistor with a 5% tolerance and a 20ppm/K temperature coefficient. But I'm not 100% certain due to the range of resistor coding systems.
From the size I estimate it to have a 2 watt rating.
As it looks in pretty bad shape, don't just replace the resistor - try and find out what caused this.
