During the quarter ended September 30, 2014, HCA recorded two changes in estimates which had the net effect of increasing revenues $26 million. The Company recorded $94 million of Medicare revenues as the estimated settlement amount for certain claims denied by Recovery Audit Contractors (“RAC”) entities conducting reviews on behalf of the Centers for Medicare & Medicaid Services (“CMS”) and currently in the pending appeals process. CMS is offering an administrative agreement to providers willing to withdraw their pending appeals in exchange for a timely partial payment (generally 68 percent of the claim amount, subject to certain adjustments). The Company also recorded a $68 million reduction to Medicaid revenues related to the Texas Medicaid Waiver Program. On October 1, 2014, the Texas Health and Human Services Commission (“THHSC”) issued a notice to hospitals participating in the Texas Medicaid Waiver Program. According to the notice, a review conducted by CMS identified certain local government/hospital affiliations it believes may be inconsistent with the waiver. As a result of these findings, CMS notified THHSC that it is deferring the federal portion of the Medicaid payments associated with these affiliations while it completes its review.

Same facility revenue per equivalent admission increased 3.8 percent in the third quarter of 2014 compared to the third quarter of 2013, reflecting improved payor mix and growth in case mix, or acuity, of 2.0 percent on a same facility basis in the quarter.

Same facility equivalent admissions increased 4.1 percent in the third quarter of 2014 compared to the prior year period. Same facility admissions increased 2.8 percent compared to the prior year period. Same facility emergency room visits increased 7.3 percent in the third quarter of 2014, compared to the prior year period. Same facility inpatient surgeries increased 1.4 percent, while same facility outpatient surgeries increased 1.9 percent in the third quarter of 2014 compared to the same period of 2013.

During the third quarter of 2014, salaries and benefits, supplies and other operating expenses totaled $7.438 billion, or 80.7 percent of revenues, compared to $6.937 billion, or 82.0 percent of revenues, in the third quarter of 2013.

Nine Months Ended September 30, 2014

Revenues for the nine months ended September 30, 2014 totaled $27.282 billion compared to $25.346 billion in the same period of 2013. Net income attributable to HCA Holdings, Inc. was $1.348 billion, or $2.98 per diluted share, compared to $1.132 billion, or $2.44 per diluted share, for the first nine months of 2013.

Balance Sheet and Cash Flows from Operations

As of September 30, 2014, HCA Holdings, Inc.’s balance sheet reflected cash and cash equivalents of $515 million, total debt of $28.470 billion, and total assets of $29.825 billion. During the third quarter of 2014, capital expenditures totaled $569 million, excluding acquisitions. Cash flows provided by operating activities in the quarter totaled $1.128 billion compared to $900 million in the third quarter of 2013. The $228 million increase in cash flows from operating activities related primarily to the combined impact of a $144 million increase in net income and a $58 million benefit from changes in income taxes for the third quarter of 2014 compared to the third quarter of 2013.

As of September 30, 2014, HCA’s leverage ratio as measured by Total Debt/Adjusted EBITDA was 3.96x, compared to 4.32x as of December 31, 2013. As of September 30, 2014, HCA operated 165 hospitals and 113 freestanding surgery centers.

In October 2014, HCA Inc. completed a $2 billion bond offering consisting of $1.4 billion 5.25% senior secured notes due 2025 and $600 million 4.25% senior secured notes due 2019. Net proceeds will be used to redeem the Company’s existing $1.4 billion 7.25% senior secured notes due 2020, to pay related fees and expenses and for general corporate purposes.

Today, the Company also announced the signing of an agreement to acquire CareNow, a privately-held company with 24 urgent care centers in the Dallas – Fort Worth area. Terms of the agreement were not disclosed. HCA expects to complete the transaction in the fourth quarter of this year.
