Accounting Policies [Abstract]
Fair Value Transfer Policy	Fair value is the price that would be received from selling an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. In determining fair value for assets and liabilities required or permitted to be recorded at fair value, the Company considers the principal or most advantageous market in which it would transact and also considers assumptions that market participants would use when pricing the asset or liability. The Company applies fair value measurements for both financial and non-financial assets and liabilities. The Company does not have any non-financial assets or liabilities that are required to be measured at fair value on a recurring basis as of October 31, 2015. The fair value of the Company’s financial instruments, including cash and cash equivalents, accounts receivable, restricted cash, accounts payable and accrued liabilities, approximate cost because of their short maturities. The fair value accounting guidance permits companies to elect fair value measurement for many financial instruments and certain other items that are not required to be accounted for at fair value. The Company did not elect fair value measurement for any eligible financial instruments or other assets. Fair Value Hierarchy The Company utilizes a fair value hierarchy that maximizes the use of observable inputs and minimizes the use of unobservable inputs when measuring fair value. A financial instrument’s categorization within the fair value hierarchy is based upon the lowest level of input that is significant to the fair value measurement. There are three levels of inputs that may be used to measure fair value: Level 1 Observable inputs that reflect quoted prices in active markets for identical assets or liabilities. Brocade’s assets utilizing Level 1 inputs include money market funds. Level 2 Inputs that reflect quoted prices for similar assets or liabilities in active markets, quoted prices for identical assets or liabilities in less-active markets, or model-derived valuations in which significant inputs are observable or can be derived principally from, or corroborated by, observable market data. Brocade’s assets and liabilities utilizing Level 2 inputs include derivative instruments. The Company uses observable market prices for comparable instruments to value its derivative instruments. Level 3 Unobservable inputs that reflect the Company’s own assumptions incorporated in valuation techniques used to determine fair value. These assumptions are required to be consistent with market participant assumptions that are reasonably available. Brocade has no assets or liabilities utilizing Level 3 inputs. During the fiscal year ended October 31, 2015, the Company had no transfers between levels of the fair value hierarchy of its assets and liabilities measured at fair value.

Fair Value Hierarchy

The Company utilizes a fair value hierarchy that maximizes the use of observable inputs and minimizes the use of unobservable inputs when measuring fair value. A financial instrument’s categorization within the fair value hierarchy is based upon the lowest level of input that is significant to the fair value measurement. There are three levels of inputs that may be used to measure fair value:

Level 1

Observable inputs that reflect quoted prices in active markets for identical assets or liabilities. Brocade’s assets utilizing Level 1 inputs include money market funds.

Level 2

Inputs that reflect quoted prices for similar assets or liabilities in active markets, quoted prices for identical assets or liabilities in less-active markets, or model-derived valuations in which significant inputs are observable or can be derived principally from, or corroborated by, observable market data. Brocade’s assets and liabilities utilizing Level 2 inputs include derivative instruments. The Company uses observable market prices for comparable instruments to value its derivative instruments.

Level 3

Unobservable inputs that reflect the Company’s own assumptions incorporated in valuation techniques used to determine fair value. These assumptions are required to be consistent with market participant assumptions that are reasonably available. Brocade has no assets or liabilities utilizing Level 3 inputs.

During the fiscal year ended October 31, 2015, the Company had no transfers between levels of the fair value hierarchy of its assets and liabilities measured at fair value.
