Intel Corp's orders and billing patterns so far in the second quarter have been slightly better than expected, Chief Executive Paul Otellini said on Tuesday.

We are halfway through Q2, Otellini told investors. In terms of our order pattern and our billing pattern, it's a little better than expected, he said.

Otellini added that second-quarter sales are dependent on the month of June, but so far, so good.

Shares of Intel rose 4 percent to $15.80 in after-hours trading, from their Nasdaq close of $15.21.
