Electronic – Deep sleep mode consumption of PIC

I would like to know why my PIC which when I put in to deep sleep does consume more than what is specified by the datasheet. I have connected a precision current meter and found that when I load the code which makes the controller to enter deep sleep it consumes 0.27mA as to the 860nA rating given. I would like to have your insight for the problem. I have done the testing on a PCB with crystal for 16 MHz and for RTCC. Why is it showing this much consumption?
