Reporting Segment	REPORTING SEGMENT — On May 3, 2017, the company announced an enhanced organizational structure designed to provide greater focus on the company’s long-term strategic objectives, emphasize brand growth and innovation in line with a national branded food company, drive enhanced accountability, and reduce costs. The new organizational structure establishes two business units (“BUs”), Fresh Packaged Bread and Snacking/Specialty, and realigns key leadership roles. The new structure also provides for centralized marketing, sales, supply chain, shared-services/administrative, and corporate strategy functions, each with clearly defined roles and responsibilities. The company has concluded that under the new organizational structure the company has one operating segment based on the nature of products the company sells, intertwined production and distribution model, the internal management structure and information that is regularly reviewed by the chief executive officer (“CEO”), who is the chief operating decision maker, for the purpose of assessing performance and allocating resources. Capital allocations, such as building a new bakery or other investments, impact both BUs, as the two BUs are so intertwined in the production of products, sales, marketing and other functions. Beginning with the first quarter of 2019, the comparative periods are presented on a consolidated basis due to the change to a single operating segment.
Leases	Leases. Primarily, the company leases real estate for manufacturing and office use, along with production and IT equipment. The company applies the new guidance to individual leases of assets, except for certain leases that employ the portfolio method. See below for the company’s policy around application of the portfolio method. When the company receives substantially all the economic benefits from and directs the use of specified property, plant and equipment, transactions give rise to leases. See Note 4, Leases, of Notes to Condensed Consolidated Financial Statements of this Form 10-Q for further qualitative and quantitative information around the company’s lease portfolio. Our classes of assets include: land; buildings; machinery and equipment; furniture, fixtures and transportation equipment; and construction in progress. The company has elected the practical expedient within the guidance to not separate lease and non-lease components within lease transactions for the following classes of assets: land; buildings; and furniture, fixtures and transportation equipment. The company has elected the short-term lease exception (lessee only) for all classes of assets and does not apply the recognition requirements for leases of 12 months or less. Lease payments for short-term leases are recognized as expense either straight-line over the lease term or as incurred depending on whether the lease payments are fixed or variable. These elections are applied consistently for all leases. The company has elected to apply a portfolio approach for leases with similar terms and conditions, commencement dates, and executed at or near the same time as one another, as it is reasonably expected that application of the lease model to the portfolio would not differ materially from application to the individual leases. The company allocates consideration (i.e., lease payments) to the lease and non-lease components within a transaction on a relative stand-alone price basis to lease and non-lease components within a transaction. The company will use the applicable incremental borrowing rate at lease commencement to perform the lease classification tests on lease components and to measure the lease liabilities and right-of-use assets in situations when discount rates implicit in leases cannot be readily determined. We will also apply the “bright-line” thresholds within the guidance for lease classification for all classes of assets.

REPORTING SEGMENT — On May 3, 2017, the company announced an enhanced organizational structure designed to provide greater focus on the company’s long-term strategic objectives, emphasize brand growth and innovation in line with a national branded food company, drive enhanced accountability, and reduce costs.

The new structure also provides for centralized marketing, sales, supply chain, shared-services/administrative, and corporate strategy functions, each with clearly defined roles and responsibilities.

Leases

Leases. Primarily, the company leases real estate for manufacturing and office use, along with production and IT equipment. The company applies the new guidance to individual leases of assets, except for certain leases that employ the portfolio method. See below for the company’s policy around application of the portfolio method.

When the company receives substantially all the economic benefits from and directs the use of specified property, plant and equipment, transactions give rise to leases. See Note 4, Leases, of Notes to Condensed Consolidated Financial Statements of this Form 10-Q for further qualitative and quantitative information around the company’s lease portfolio. Our classes of assets include: land; buildings; machinery and equipment; furniture, fixtures and transportation equipment; and construction in progress.
