And before we get started, a few words about forward-looking statements. In the course of this teleconference, management may make forward-looking statements. Forward-looking statements involve assumptions, risk and uncertainties that could cause actual results to differ materially from those statements. For more information and a discussion of such assumptions, risks and uncertainties, please see the press release and filings made by Harris with the SEC.
In addition, in our press release and on this teleconference and the related presentation, we will discuss certain financial measures and information that are non-GAAP financial measures. A reconciliation to the comparable GAAP measures is included in tables of our press release and on the Investor Relations section of our website, which is www.harris.com.

And with that, Bill, I turn the call over to you.
William M. Brown
Thank you, Pam, and welcome to our Third Quarter Fiscal 2012 Earnings Call. I'll quickly review some of the highlights of our third quarter results, turn it over to Gary to walk through the details of the financials and then come back to you with a few comments before opening the call to questions.
Turning to Slide 3 and 4 in the presentation. Harris posted solid third quarter results with orders, revenue and non-GAAP earnings all higher compared to prior year. Revenue increased 4% to $1.48 billion and book-to-bill was greater than 1. Non-GAAP EPS of $1.39 increased 18% over the prior year and was driven by operating income growth at RF and government communications, nonrecurring royalty income and a lower share count from first quarter repurchases.
In the last call, I say we are going to be conservative on cash deployment with a focus on rewarding shareholders. We resolved a significant financial drag from the cyber hosting facility, and completed a thorough review of our business portfolio, and we've made good progress on all 3 fronts. The company continues to generate strong free cash flow and at the end of February, we increased our dividend by 18% and raised our target payout ratio from 20% to 25%. We also announced in the third quarter that we are exiting the underutilized cyber hosting facility, and the process to divest the assets is progressing quickly. Our business portfolio review was well underway and today, we're announcing the decision to divest Broadcast Communications, which we believe is no longer aligned with the company's long-term strategy. The combination of a lack of effective integration by the company over the last decade, coupled with the market outlook that is not as promising today as once believed, led us to conclude that the best -- that the business is best owned by another party. Although broadcast is no longer core to our company, we believe the business has the potential for strong growth and margin expansion, is led by a solid leadership team and has long-term value for someone who brings a focused approach to the broadcast and media market. It's our intention to use the proceeds to return cash to shareholders and invest in growing our core businesses.
