Debt includes the accounts receivable securitization program, Senior Notes, revolving credit facilities and other indebtedness as described in Note 10, Debt. We also have letters of credit of $5.9 million and $10.6 million outstanding for December 31, 2016 and 2015, respectively. Letters of credit are provided by our debt facility.

We have future obligations under certain operating leases. The operating leases, which include facilities, data processing and other equipment, have remaining lease terms ranging from 1 to 10 years excluding options to extend the leases for various lengths of time. Certain leases have clauses that call for the annual rents to be increased during the term of the lease. Such lease payments are expensed on a straight-line basis. We also lease certain facilities from unconsolidated real estate affiliates.

The following rental costs were incurred (in millions):



	Year Ended December 31,
	2016		2015		2014
Rent expense	$	22.2	$	23.6	$	26.8
Occupancy expenses included in above amounts that were charged by unconsolidated real estate affiliates	5.9		6.8		11.4

Obligations under software license agreements generally relate to purchase obligations under maintenance agreements that support the software license.

We have entered into agreements with certain officers whereby upon defined circumstances constituting a change in control of the Company, certain benefit entitlements are automatically funded and such officers are entitled to specific cash payments upon termination of employment. Additionally, we have adopted the DST Systems, Inc. Executive Severance Plan which provides certain benefits to participants in the event of a qualifying termination under the plan.

We are involved in various legal proceedings arising in the normal course of our business. While the ultimate outcome of these legal proceedings cannot be predicted with certainty, it is the opinion of management, after consultation with legal counsel, that the final outcome in such proceedings, in the aggregate, would not have a material adverse effect on our consolidated financial condition, results of operations and cash flows.

Other contractual commitments

In the normal course of business, to facilitate transactions of services and products and other business assets, we have agreed to indemnify certain parties with respect to certain matters. We have agreed to hold certain parties harmless against losses arising from a breach of representations or covenants, data and confidentiality obligations, or out of intellectual property infringement or other claims made by third parties. These agreements may limit the time within which an indemnification claim can be made and the amount of the claim. At December 31, 2016, except for certain immaterial items, there were no liabilities for guarantees or indemnifications as it is not possible to determine either the maximum potential amount under these indemnification agreements or the timing of any such payments due to the limited history of prior indemnification claims and the unique facts and circumstances involved in each particular agreement. Historically, payments made under these agreements have not had a material impact on our consolidated financial position, results of operations or cash flows.
