Fair Value Disclosures [Abstract]
Employee Loans	The housing loans are measured using the Level 3 inputs within the fair value hierarchy under FASB ASC Topic 820, Fair Value Measurement because they are valued using significant unobservable inputs. The fair value of employee housing loans is estimated using information on the rates of return that market participants in Belarus would require when investing in unsecured U.S. dollar-denominated government bonds with similar maturities (a “risk-free rate”), after taking into consideration any applicable credit and liquidity risk. They are subsequently carried at amortized cost less allowance for loan losses, which have been minimal since the commencement of the program as participants go through a rigorous approval and screening process. Any difference between the carrying value and the fair value of a loan upon initial recognition is charged to expense.
