The sales of most of our products are subject to significant competition due to factors including product quality and taste, brand awareness among consumers, access to shelf space at retail customers' locations, price, advertising and promotion, innovation of on-trend snacks, variety of snacks offered, nutritional content, product packaging and package design. We compete in the snack food market against numerous multinational, regional and local companies, as well as emerging companies, including in the BFY product subcategory, principally on the basis of product taste and quality, but also brand recognition and loyalty, price, marketing, advertising and the ability to satisfy specific consumer dietary needs.
Due to the competitive landscape in the snack food industry, price increases for our products that we initiate or failure to effectively advertise and promote our products may negatively impact our financial results if not properly implemented or accepted by our customers, IOs, third-party distributors or consumers. Substantial advertising and promotional expenditures may also be required to maintain or improve our brands' market position or to introduce a new product to the market, and participants in our industry may be engaging in new advertising trends or channels which we are not. Historically, we have offered a variety of sales and promotion incentives to our customers, IOs, third-party distributors and consumers, such as price discounts, consumer coupons, volume rebates, cooperative marketing programs, product placement fees and in-store displays, often in connection with seasonal social events, holidays and sporting events. The promotional environment has intensified in recent years, including but not limited to robust promotional launches, and .we have been, and may in the future be, limited in our ability to increase prices or adjust product sizes sufficiently on a timely basis, or at all, in order to offset increased input costs, such as raw materials, packaging, energy, freight, labor, and overhead costs or other expenditures, such as advertising and promotion costs, which has the effect of reducing overall sales volume, revenue and operating profit. In addition, advertising and promotional expenditures may be ineffective if consumers prioritize price over other factors and purchase lower-cost alternatives, such as private label, generic or store branded products.
Our ability to compete may also be dependent on the availability of product category-appropriate snack aisles at our retail customers' locations and whether our products are placed in the appropriate snack aisle, such as the BFY snack food aisle or in the traditional snack food aisle. An increasing focus on BFY products and other specialty products in the marketplace will likely increase these competitive pressures within the category in future periods. Further, companies in the BFY product segment providing innovative or trendy snack foods often receive investments from private equity, venture capital or other investors, who may be more willing to accept lower product margins or sustained losses in order to gain market share. If such emerging companies are able to attract a loyal consumer base through more innovative or trendier snack foods or offer their snack food products at lower prices than us, our market share and results of operations may be materially and adversely affected.
If our advertising or promotional efforts do not increase brand awareness or sales of our products, our expenses may increase without a corresponding increase in revenue, and our operating profit may be reduced. Additionally, if market prices for certain inputs decline significantly, in some instances we may be required by contract to pay customers the difference or experience customer pressure to reduce the prices for our products, which could lower our revenue and operating profit.
There is continuing consolidation in the snack food industry and in retail outlets for snack foods by other market participants. Although we benefit from the execution of our own acquisition strategy within the snack food industry and with respect to snack distribution channels, ongoing consolidation in the snack food industry and retail outlets by others may prevent us from effectively competing if others in the industry that have greater resources than us or if retail customers or potential retail customers enter into long-term purchase contracts or promotional arrangements. Significant consolidation by others increases the possibility that we could lose one or more major customers, lose existing product authorizations or shelf space at customer locations, or lose market share. For example, our competitors vie for the same shelf placement and may offer incentives to retail customers that we cannot match, particularly as a result of consolidation. Even if we obtain shelf space or preferable shelf placement for any of our brands, our new and existing products may fail to achieve the sales expectations set by our retail customers, potentially causing these retailers to remove our products from the shelf or place them in less favorable locations. Additionally, an increase in the number and quality of private-label products in the product categories in which we compete has reduced available shelf space and could continue to hamper the placement for our branded products, which could adversely affect our sales. To obtain and keep shelf placement for our products, we may need to increase our marketing and advertising spending in order to create consumer awareness, protect and grow our existing market share or to promote new products, which could impact our operating results. We also consistently evaluate our product lines to determine whether it may be necessary to discontinue certain products. Discontinuing product lines may increase our profitability but could reduce our sales and hurt our brand and consumer loyalty, and a reduction in sales of certain of our products could result in a reduction in sales of other of our products.
