Confusion regarding classification accuracy calculation and result
You might want to take a look at the confusion matrix  wiki page.

Accuracy = (TP + TN) / (P + N) = (26 + 1473)/1500 = 99.9%

I guess, if you want the break down by the class, it would have been:
1473/1473
and
26/27, but you have 1500 as the denominator in both classes.

Even though I think conventionally most people report on the entire model rather than just on a particular class.
