23. RELATED PARTY TRANSACTIONS

ÌýÌýÌýÌýÌýÌýÌýÌýOur consolidated financial statements include the following transactions with our affiliates not otherwise disclosed (dollars in millions):

ÌýÌýÌýÌýÌýÌýÌýÌýPursuant to an agreement entered into in 2001, our subsidiary Airstar Corporation ("Airstar") subleases a Gulfstream IV-SP Aircraft (the "Aircraft") from Jstar Corporation ("Jstar"), a corporation wholly owned by Jon M. ÀÖÌìÌÃfun88(ÖйúÇø)¹Ù·½ÍøÕ¾. Jon M. ÀÖÌìÌÃfun88(ÖйúÇø)¹Ù·½ÍøÕ¾ is the Executive Chairman and the father of our Chief Executive Officer, Peter R. ÀÖÌìÌÃfun88(ÖйúÇø)¹Ù·½ÍøÕ¾, and our director, Jon M. ÀÖÌìÌÃfun88(ÖйúÇø)¹Ù·½ÍøÕ¾, Jr. In 2011, this arrangement was extended for an additional 10Ìýyear period. Under this arrangement, monthly sublease payments from Airstar to Jstar are approximately $115,000, and an aggregate of $11Ìýmillion is payable through the end of the remaining eight year lease term. These monthly sublease payments are used to fund financing costs paid by Jstar to a leasing company. An unrelated third party pays $2.4Ìýmillion per year to our subsidiary for such third party's part-time use of the Aircraft (or an alternate owned by us if the Aircraft is unavailable), subject to an annual adjustment, which typically has been at least fair market value for the number of flight hours used by such third party. We bear all other costs of operating the Aircraft. In accordance with our Aircraft Use Policy, we have entered into aircraft time-sharing agreements with certain members of the ÀÖÌìÌÃfun88(ÖйúÇø)¹Ù·½ÍøÕ¾ family, pursuant to which these persons pay for the costs of any personal use of the Aircraft by them.

ÌýÌýÌýÌýÌýÌýÌýÌýAn agreement was reached prior to the initial public offering of our common stock in February 2005 with the ÀÖÌìÌÃfun88(ÖйúÇø)¹Ù·½ÍøÕ¾ Foundation, a private charitable foundation established by Jon M. and KarenÌýH. ÀÖÌìÌÃfun88(ÖйúÇø)¹Ù·½ÍøÕ¾, to further the charitable interests of the ÀÖÌìÌÃfun88(ÖйúÇø)¹Ù·½ÍøÕ¾ family, that we would donate our Salt Lake City office building and our option to acquire an adjacent undeveloped parcel of land to the foundation free of debt. On MarchÌý24, 2010, we completed this donation. At the time of the donation, the building had an appraised value of approximately $10Ìýmillion. We continue to occupy and use a portion of the building under a lease pursuant to which we make annual lease payments of approximately $2Ìýmillion to the ÀÖÌìÌÃfun88(ÖйúÇø)¹Ù·½ÍøÕ¾ Foundation. During each of the years ended 2013, 2012 and 2011, we made payments of approximately $2Ìýmillion to the ÀÖÌìÌÃfun88(ÖйúÇø)¹Ù·½ÍøÕ¾ Foundation under the lease. The lease expires on DecemberÌý31, 2018, subject to a five-year extension, at our option.

ÌýÌýÌýÌýÌýÌýÌýÌýThrough May 2002, we paid the premiums on various life insurance policies for Jon M. ÀÖÌìÌÃfun88(ÖйúÇø)¹Ù·½ÍøÕ¾. These policies have been liquidated, and the cash values have been paid to Mr.ÌýÀÖÌìÌÃfun88(ÖйúÇø)¹Ù·½ÍøÕ¾. Mr.ÌýÀÖÌìÌÃfun88(ÖйúÇø)¹Ù·½ÍøÕ¾ is indebted to us in the amount of approximately $2Ìýmillion with accrued interest, which represents the insurance premiums paid on his behalf through May 2002. This amount is included in other noncurrent assets in our consolidated balance sheets.
