DEBT

Short-Term Debt

On September 15, 2014, we entered into a five year credit agreement, which provides for a $300 million unsecured credit facility that will expire on November 1, 2019. On July 21, 2015, the total amount available under the credit facility was increased to $450 million. The company may use amounts borrowed under the facility for general corporate purposes. As of July 31, 2016, we had no borrowings outstanding under the credit facility. We were in compliance with the covenants of the credit facility during the nine months ended July 31, 2016.

As a result of the Anite acquisition, we have an overdraft facility of £25 million that expired on July 31, 2016, but by mutual agreement this facility continues to be available while a replacement short-term facility is negotiated. As of July 31, 2016, we had no borrowings outstanding under the facility. We were in compliance with the covenants of the facility during the nine months ended July 31, 2016.

Long-Term Debt

The following table summarizes the components of our long-term debt:



	July 31, 2016		October 31, 2015
	(in millions)
3.30% Senior Notes due 2019	$	500	$	499
4.55% Senior Notes due 2024	600		600
Total	$	1,100	$	1,099

The notes issued are unsecured and rank equally in right of payment with all of our other senior unsecured indebtedness. There have been no changes to the principal, maturity, interest rates and interest payment terms of the senior notes, detailed in the table above, during the nine months ended July 31, 2016 as compared to the senior notes described in our Annual Report on Form 10-K for fiscal year ended October 31, 2015.

In March 2016, we assumed approximately $1 million of long-term debt in connection with an acquisition. In May 2016, this debt was subsequently repaid in full.

As of July 31, 2016 and October 31, 2015, we had $16 million and $19 million, respectively, of outstanding letters of credit unrelated to the credit facility that were issued by various lenders.

The fair value of our long-term debt, calculated from quoted prices that are primarily Level 1 inputs under the accounting guidance fair value hierarchy, was above the carrying value by approximately $36 million and was below the carrying value by $8 million as of July 31, 2016 and October 31, 2015, respectively.
