Accounts receivable securitization program

DST securitizes certain of its domestic accounts receivable through an accounts receivable securitization program with a third-party bank. The maximum amount that can be outstanding under this program is $150.0 million. The facility will expire by its terms on May 15, 2014, unless renewed.

The outstanding amount under the program was $150.0 million at both March 31, 2014 and December 31, 2013. During the three months ended March 31, 2014 and 2013, total proceeds from the accounts receivable securitization program were approximately $240.8 million and $226.5 million, respectively, and total repayments were approximately $240.8 million and $226.5 million, respectively.

Revolving credit facilities

The Company has a syndicated line of credit facility which provides for a revolving unsecured credit facility in an aggregate principal amount of up to $630.0 million. On April 17, 2014, the Company amended the syndicated line of credit facility to, among other items, allow for certain additional dispositions of non-operating assets, the proceeds of which are to be used to repurchase outstanding shares owned by the Argyros Family Trust and certain of its affiliates (collectively, "Argyros Group") which beneficially owned approximately 9.2 million shares or 22% of DST common shares as of March 23, 2014.

Senior Notes

DST has $370.0 million of outstanding privately placed senior notes (collectively, the "Senior Notes") at both March 31, 2014 and December 31, 2013. On April 17, 2014, the Company received a consent from the holders of a majority of the Senior Notes whereby the noteholders consented to the Company's proposed repurchase of DST common stock by the Company from the Argyros Group and other related matters.

Fair value

Based upon the borrowing rates currently available to the Company and its subsidiaries for indebtedness with similar terms and average maturities, the carrying value of long-term debt, with the exception of the Senior Notes, is considered to approximate fair value. The estimated fair values of the Senior Notes were derived principally from quoted prices for similar financial instruments (Level 2 in the fair value hierarchy).

As of March 31, 2014 and December 31, 2013, the carrying and estimated fair values of the Senior Notes were as follows (in millions):



	March 31, 2014				December 31, 2013
	Carrying Value		Estimated Fair Value		Carrying Value		Estimated Fair Value
Senior notes - Series A	$	40.0	$	40.7	$	40.0	$	40.6
