Revenue	Note 2—Revenue The Company disaggregates its consolidated revenues by reportable segment, as Management evaluates the nature, amount, timing and uncertainty of the Company’s revenues by segment. Refer to Note 12—Segment Information herein as well as the information below regarding the Company’s reportable segments. Housekeeping Housekeeping accounted for approximately 48.5%, or $734.2 million, and 53.7%, or $733.7 million, of the Company’s consolidated revenues for the nine months ended September 30, 2018 and 2017, respectively. The services provided under this segment include managing clients’ housekeeping departments, which are principally responsible for the cleaning, disinfecting and sanitizing of resident rooms and common areas of the clients’ facilities, as well as the laundering and processing of the bed linens, uniforms, resident personal clothing and other assorted linen items utilized at the clients’ facilities. Upon beginning service with a client facility, the Company will typically hire and train the employees previously employed by such facility and assign an on-site manager to supervise and train the front-line personnel and coordinate housekeeping services with other facility support functions in accordance with client requests. Such management personnel also oversee the execution of various cost and quality control procedures including continuous training and employee evaluation, and on-site testing for infection control. Dietary Dietary services represented approximately 51.5%, or $778.2 million, and 46.3%, or $633.0 million, of the Company’s consolidated revenues for the nine months ended September 30, 2018 and 2017, respectively. Dietary services consist of managing clients’ dietary departments which are principally responsible for food purchasing, meal preparation and professional dietitian services, which include the development of menus that meet the dietary needs of residents. On-site management is responsible for all daily dietary department activities, with regular support being provided by a District Manager specializing in dietary services, as well as a registered dietitian. The Company also offers clinical consulting services to facilities which if contracted is a service bundled within the monthly service provided to clients.

Revenue Recognition Substantially all of the Company's revenues are derived from contracts with customers. The Company accounts for revenue from contracts with customers in accordance with ASC 606, and as such, the Company recognizes revenue to depict the transfer of promised goods and services to customers in amounts that reflect the consideration to which the Company expects to be entitled in exchange for those goods and services. The Company’s costs of obtaining contracts are not material. The Company performs services and provides goods in accordance with contracts with its customers. Such contracts typically provide for a renewable one year service term, cancelable by either party upon 30 to 90 days' notice, after an initial period of 60 to 120 days. A performance obligation is a promise in a contract to transfer a distinct good or service to the customer and is defined as the unit of account under ASC 606. The Company’s Housekeeping and Dietary contracts relate to the provision of bundles of goods, services or both, which represent a series of distinct goods and services and that are substantially the same and that have the same pattern of transfer to the customer. Accordingly, the Company accounts for the series as a single performance obligation satisfied over time, as the customer simultaneously receives and consumes the benefits of the goods and services provided. Revenue is recognized using the output method, which is based upon the delivery of goods and services to the clients’ facilities. In limited cases, the Company provides goods, services or both, before the execution of a written contract. In these cases, the Company defers the recognition of revenue until a contract is executed. The amount of such deferred revenue was not material as of September 30, 2018 and December 31, 2017. The transaction price is the amount of consideration to which the Company expects to be entitled in exchange for transferring promised goods or services to its customers. The transaction price does not include taxes assessed or collected. The Company’s contracts detail the fees that the Company charges for the goods and services it provides. For certain contracts which contain a variable component to the transaction price, the Company is required to make estimates of the amount of consideration to which the Company will be entitled, based on variability in resident and patient populations serviced, product usage or quantities consumed. The Company recognizes revenue related to such estimates only when Management determines that there will not be a significant reversal in the amount of revenue recognized. The Company’s contracts generally do not contain significant financing components, as the contracts contain payment terms that are less than one year. The Company allocates the transaction price to each performance obligation, noting that the bundle of goods, services or goods and services provided under each Housekeeping and Dietary contract represents a single performance obligation that is satisfied over time. The Company recognizes the related revenue when it satisfies the performance obligation by transferring a bundle of promised goods, services or both to a customer. Such recognition is on a monthly or weekly basis, as goods are provided and services are performed. In some cases, the Company requires customers to pay in advance for goods and services to be provided. As of September 30, 2018 and December 31, 2017, the value of the associated contract liabilities was not material. Transaction Price Allocated to Remaining Performance Obligations The Company recognizes revenue as it satisfies the performance obligations associated with contracts with customers, which due to the nature of the goods and services provided by the Company, are satisfied over time. Contracts may contain transaction prices that are fixed, variable or both. The significant majority of the Company’s contracts with customers have an initial term of one year or less, with renewable one year service terms, cancelable by either party upon 30 to 90 days’ notice after an initial period of 60 to 120 days. For the purpose of disclosing the transaction price allocated to remaining performance obligations, the Company elected to apply practical expedients available under the guidance in ASC 606 to exclude from the calculation future revenues expected for the performance of services under contracts with variable consideration that are for a term of one year or less. Although only a small portion of the Company’s contracts have an original expected duration that exceeds one year, the Company has historically had, and expects to continue to have, favorable client retention rates. As of September 30, 2018, the revenue expected to be recognized with the fixed transaction price associated with the remaining performance obligations under the Company’s existing contracts with a term greater than one year is $67.9 million for the remainder of 2018, $271.7 million for 2019, $271.7 million for 2020, $271.7 million for 2021, $271.7 million for 2022 and $339.6 million thereafter.
